[v1.03] Apply refactoring in src/common/udev.c

Latest versions of windows have support for the parsing VT100 escape
code sequences, allowing for terminal colors similar to Linux.

https://docs.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences#screen-colors

Here I have it get the console mode, set the
`ENABLE_VIRTUAL_TERMINAL_PROCESSING` flag, and then grab the console
mode again to both verify that VT100 escape sequences are supported and
that it is enabled after setting it to determine if the printer should
allow for fancy-color mode.

+
+## 1. cpufetch does not accept pull requests
+cpufetch is a small project, and I enjoy developing it. There are for sure some bugs and exciting features to add, but I prefer to make these
+changes myself. For that reason, you should always use the issues page to report anything related to cpufetch. In the rare case that there is
+a concise bug or feature that I am unable to implement myself, I will enable pull requests for this.
+
+## 2. Creating an issue
+
+### 2.1: I found a bug in cpufetch (the program provides incorrect / invalid information)
+In the github issue **you must include**:
+- Exact CPU model.
+- Operating system.
+- The output of `cpufetch`.
+- The output of `cpufetch --debug`.
+
+### 2.2: I found a bug in cpufetch (the program crashes / does not work properly)
+- Exact CPU model.
+- Operating system.
+- The output of `cpufetch`.
+- The output of `cpufetch --debug`.
+- A stacktrace (if program crashes):
+
+#### Stacktrace option 1 (best)
+1. Build cpufetch with debug symbols (`make clean; make debug`).
+2. Install valgrind (if it is not already installed)
+3. Run cpufetch with valgrind (`valgrind ./cpufetch`)
+4. Paste the complete output (preferably on a platform like pastebin)
+
+#### Stacktrace option 2 (use this option if option 1 does not work)
+1. Build cpufetch with debug symbols (`make clean; make debug`).
+2. Install gdb (if it is not already installed)
+3. Debug cpufetch with gdb (`gdb cpufetch`)
+3. Run cpufetch (just r inside gdb console)
+4. Paste the complete output (preferably on a platform like pastebin)
+
+### 2.3: I have an idea for a new feature in cpufetch / I want to suggest a change in cpufetch
+Just explain the feature in the issue and include references (links) to relevant sources if appropriate.

+                            Preamble
 
-The above copyright notice and this permission notice shall be included in all
-copies or substantial portions of the Software.
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
 
-THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
-IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,
-FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE
-AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER
-LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM,
-OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
-SOFTWARE.
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

-### Implementation
+## 4. Colors
+By default, `cpufetch` will print the CPU logo with the system colorscheme. However, you can set a custom color scheme in two different ways:
 
-`cpufetch` makes use of two techniques to fetch data:
-* __cpuid__: CPU name, number of threads per core and instructions features are fetched via _cpuid_. See [this](http://www.sandpile.org/x86/cpuid.htm) and [Intel  Processor Identification and the CPUID Instruction](https://www.scss.tcd.ie/~jones/CS4021/processor-identification-cpuid-instruction-note.pdf) for more information.
-* __udev__: Cache and frequency are fetched via _udev_, by looking at specific files from `/sys/devices/system/cpu`
+### 4.1 Specifying a name
 
-### Bugs or improvements
-Feel free to open a issue on the repo to report a issue or propose any improvement in the tool
+ By specifying a name, cpufetch will use the specific colors of each manufacture. Valid values are:
+
+- intel
+- intel-new
+- amd
+- ibm
+- arm
+
+```
+./cpufetch --color intel (default color for Intel)
+```
+
+### 4.2 Specifying the colors in RGB format
+
+5 colors must be given in RGB with the format: ``[R,G,B:R,G,B:R,G,B:R,G,B:R,G,B]``. These colors correspond to the CPU logo color (first 3 colors) and for the text colors (following 2).
+
+```
+./cpufetch --color 239,90,45:210,200,200:0,0,0:100,200,45:0,200,200
+```

+.SH LOGOS
+.TP
+cpufetch will try to adapt the logo size and the text to the terminal width. When the output (logo and text) is wider than the terminal width, cpufetch will print a smaller version of the logo (if it exists). This behavior can be overridden by \fB\-\-logo\-short\fR  and \fB\-\-logo\-long\fR, which always sets the logo size as specified by the user, even if it is too big. After the logo selection (either automatically or set by the user), cpufetch will check again if the output fits in the terminal. If not, it will use a shorter name for the fields (the left part of the text). If, after all of this, the output still does not fit, cpufetch will cut the text and will only print the text until there is no space left in each line 
+.SH EXAMPLES
+.TP
+Run cpufetch with Intel color scheme:

+.SH BUGS
+.TP
+Report bugs to https://github.com/Dr\-Noob/cpufetch/issues
+.SH NOTE
+.TP
+Peak performance information is NOT accurate. cpufetch computes peak performance using the max frequency of the CPU. However, to compute the peak performance, you need to know the frequency of the CPU running AVX code. This value is not be fetched by cpufetch since it depends on each specific CPU. To correctly measure peak performance, see: https://github.com/Dr\-Noob/peakperf

+### 2. Why ARM cpufetch works on Linux based systems?
+CPUID instructions (present in x86 architectures) [[1](#references)] allow user level applications to obtain information about the CPU. In ARM architectures, there are many registers (MIDR [[2](#references)], CCSIDR [[3](#references)]) that provide information about the CPU too. However, those registers can only be read from privilege mode (PL1 or higher). Therefore, any user level tool which can actually read information about the running CPU must use the operating system to do so. cpufetch uses some Linux kernel features (see the remaining sections). Therefore, cpufetch in ARM processors is limited to Linux kernel based systems, such as __GNU/Linux__ and __Android__
+
+### 3. How to get CPU microarchitecture?
+__Involved code: [get_midr_from_cpuinfo (udev.c)](https://github.com/Dr-Noob/cpufetch/blob/master/src/arm/udev.c), [midr.c](https://github.com/Dr-Noob/cpufetch/blob/master/src/arm/midr.c)__
+
+Microarchitecture information is acquired from the Main ID Register (MIDR) [[2](#references)]. Currently, cpufetch rebuilds this register using `/proc/cpuinfo` file. While this file does not contain the value of the register per se, it contains the following fields:
+- `CPU implementer`,
+- `CPU architecture`
+- `CPU variant`
+- `CPU part`
+- `CPU revision`
+
+The MIDR register can be built with this information. Another possible approach is to read MIDR directly from `/sys/devices/system/cpu/cpu*/regs/identification/midr_el1`
+
+With the MIDR available, the approach is the same as the one used in x86_64 architectures. cpufetch has a file that acts like a database that tries to match the MIDR register with the specific CPU microarchitecture.
+
+### 4. How to get CPU topology?
+__Involved code: [get_ncores_from_cpuinfo (udev.c)](https://github.com/Dr-Noob/cpufetch/blob/master/src/arm/udev.c), [midr.c](https://github.com/Dr-Noob/cpufetch/blob/master/src/arm/midr.c)__
+
+ARM provides a new interesting architecture feature: big.LITTLE architectures [[4](#references)]. An ARM CPU can be organized like a typical x86_64 CPU, where all cores share the same microarchitecture. However, ARM big.LITTLE architecture breaks this schema. In a big.LITTLE CPU, two or more CPUs microarchitecture live in the same chip.
+
+This means that cpufetch can't just read which microarchitecture is the first core and assume that the rest of them shares the same microarchitecture. To get the CPU topology, cpufetch first reads the number of CPU cores. This can be obtained from `/sys/devices/system/cpu/present`
+
+Then, for each core, cpufetch reads the MIDR and also the frequency (see section 5). Then, cpufetch assumes that two cores are different when their MIDR are different. This idea allows cpufetch to detect big.LITTLE architectures, and to know how many cores of each architecture the running CPU has.
+
+### 5. How to get the frequency?
+Frequency is read directly from `/sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq`
+
+### 6. How to get system on chip model?
+__Involved code: [soc.c](https://github.com/Dr-Noob/cpufetch/blob/master/src/arm/soc.c)__
+
+System on chip (SoC) model is obtained using the same idea as the microarchitecture. First, SoC string is read. Then, the string has to be matched against a database-like function (__parse_soc_from_string__). The SoC string of the running CPU can be obtained using two different approaches:
+
+- Using `/proc/cpuinfo`. This is the first thing to try. Linux kernel usually provides the string under the `Hardware` keyword. However, the Linux kernel may be unable to provide this information, or this string may not be found in the database-like function.
+- Using Android properties: This only works on Android systems. Android properties can be read using `__system_property_get` function. cpufetch tries to read two properties:
+  - `ro.mediatek.platform`
+  - `ro.product.board`
+
+  If any string is returned, cpufetch tries to find a match in the database (using the same database as in the case of `/proc/cpuinfo`).
+
+The expected strings have to be hardcoded. I found two ways of knowing which string should correspond to which SoC:
+
+  - Searching on the internet. Manufacturers __usually__ provide this information. For example, Qualcomm usually publishes the chip name along with other characteristics (under the `Part` or `Part number` keyword [[6](#references)]).
+  - "Hunting" for the strings. For example, finding smartphones with a given SoC and manually reading the `/proc/cpuinfo` or the `build.prop` file. A very good resource to do this is the SpecDevice webpage [[7](#references)]).
+
+### 7. How to get cache size and topology?
+ARM architecture supports reading the cache information via some registers (for example, the CCSIDR register  [[3](#references)]). As mentioned earlier, user level applications are not able to read these registers directly. The remaining option is to ask the operating system for this information. However, at the moment, the __Linux kernel does not provide cache information__. Therefore, cpufetch does not print any cache information on ARM CPUs at the moment. There are, however, other approaches to be explored:
+
+- Read the registers in kernel mode. This can be accomplished by running a kernel module [[4](#references)]. Unfortunately, running a custom kernel module is tricky, and sometimes impossible to do reasonably (for example, in Android devices). In any case, my decision is to run cpufetch on user level only.
+- Hardcode the cache information for each SoC: Sometimes, manufacturers publish technical information about the chips, where cache topology and size are shown. This method is impractical, since this kind of information is very hard (or impossible) to find online, and the number of SoC is huge.

+__Involved code: [get_uarch_from_pvr (uarch.c)](https://github.com/Dr-Noob/cpufetch/src/ppc/uarch.c)__
+
+Microarchitecture is deduced from the PVR register, which is read using the `mfpvr` instruction. The correspondence between the PVR and the specific microarchitecture has been implemented using the values in `arch/powerpc/kernel/cputable.c` in the Linux kernel. Some of them have been removed. The manufacturing process has been queried by searching on the internet.
+
+### 3. How to get CPU topology?
+__Involved code: [get_topology_info (ppc.c)](https://github.com/Dr-Noob/cpufetch/src/ppc/ppc.c)__
+
+The total number of cores is queried using `sysconf(_SC_NPROCESSORS_ONLN)`. Then, with the number of sockets and the number of physical cores, we can calculate the number of threads per core.
+
+The number of sockets is queried using `/sys/devices/system/cpu/cpu*/topology/physical_package_id`. Once this file has been read for all of the cores, a simple custom algorithm is used to determine the number of sockets.
+
+The number of physical cores is queried using `/sys/devices/system/cpu/cpu*/topology/core_id`. Again, a custom algorithm is used to determine the number of physical cores.
+
+### 4. How to get the frequency?
+Frequency is read directly from `/sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq`
+
+### 5. How to get cache size and topology?
+Cache size is retrieved directly from Linux (using `/sys/devices/system/cpu/cpu0/cache/index*/size`).
+
+To find the cache topology, the files `/sys/devices/system/cpu/cpu0/cache/index*/shared_cpu_map` are used, and a custom algorithm is used to determine how many caches are there at each level.
+
+_NOTE_: To avoid Linux dependencies at this point, it looks like it is possible to derive the cache size and topology from the microarchitecture. For example, in the POWER9 architecture, wikichip assumes that all the POWER9 CPUs have the same cache size for each core and topology [[1](#references)].

+### 2. Why differences between Intel and AMD?
+There are many different CPUID leaves [[1](#references)]. In some cases, a given leaf does the same thing in Intel and AMD processors, but in the majority of them, they don't. For example, leaf 0x4 gives you the caches information, but in AMD is a reserved (invalid) leaf! In the case of AMD, is more common to fetch information using extended levels than using the standard levels (the other way around with Intel).
+
+### 3. How to get the frequency?
+__Involved code: [get_frequency_info (cpuid.c)](https://github.com/Dr-Noob/cpufetch/blob/master/src/x86/cpuid.c)__
+
+CPUID leaf 0x16 is used.
+
+If the CPU does not support supports such level:
+- Linux: cpufetch will try to obtain this information using `/sys` filesystem in Linux. I think that Linux knows the frequency using model specific registers (MSRs), which you can't read at the user level.
+- Windows: cpufetch can't obtain CPU frequency. This means that peak performance can't be computed because the frequency is needed to compute it.
+
+### 4. How to get cache sizes?
+__Involved code: [get_cache_info (cpuid.c)](https://github.com/Dr-Noob/cpufetch/blob/master/src/x86/cpuid.c)__
+
+- Intel: CPUID leaf 0x4 is used (using __get_cache_info_general__). If the CPU does not support it, cpufetch can't get this information.
+- AMD: Extended CPUID leaf 0x1D is used (using __get_cache_info_general__). If the CPU does not support this level, cpufetch uses a fallback method, which uses extended leaves 0x5 and 0x6. This fallback method uses __get_cache_info_amd_fallback__.
+
+
+### 5. How to get CPU microarchitecture?
+__Involved code: [get_cpu_uarch (cpuid.c)](https://github.com/Dr-Noob/cpufetch/blob/master/src/x86/cpuid.c), [get_uarch_from_cpuid (uarch.c)](https://github.com/Dr-Noob/cpufetch/blob/master/src/x86/uarch.c)__
+
+CPUID leaf 0x1 is used. From there, we get:
+- Model
+- Extended Model
+- Family
+- Extended Family
+- Stepping
+
+Knowing this information, we can distinguish any CPU microarchitecture. Inside __uarch.c__ there is a function that behaves like a database or a lookup table. The function of this database is to find a match between the information obtained from 0x1 and what kind of microarchitecture the current CPU is. I got the data using and adapting the code from Todd Allen's cpuid program [[5](#references)]. Knowing the microarchitecture, we can obtain the manufacturing process (or technology, the size in nm of the transistors).
+
+### 6. How to get CPU topology?
+__Involved code: [cpuid.h](https://github.com/Dr-Noob/cpufetch/blob/master/src/x86/cpuid.h), [get_topology_info (cpuid.c)](https://github.com/Dr-Noob/cpufetch/blob/master/src/x86/cpuid.c), [apic.c](https://github.com/Dr-Noob/cpufetch/blob/master/src/x86/apic.c)__
+
+cpufetch aims to support the most complex systems, so it supports multi-socket CPUs and detailed SMT (Intel HyperThreading) information. The CPU topology is stored in the following struct:
+
+```
+struct topology {
+  int64_t total_cores;
+  uint32_t physical_cores;
+  uint32_t logical_cores;
+  uint32_t smt_available;
+  uint32_t smt_supported;
+  uint32_t sockets;
+};
+```
+
+This structure needs a bit of explanation, to know what are we looking for:
+- `physical_cores`: Number of physical cores. In a multi socket system, this field stores the number of cores for just one socket.
+- `logical_cores`: Number of logical cores. In a multi socket system, this field stores the number of logical cores for just one socket.
+- `total_cores`: Total number of logical cores. In a multi socket system, this field stores the number of logical cores for the entire system.
+- `sockets`: How many sockets the system has.
+- `smt_supported`: Stores if SMT (or Intel HT) is supported in the CPU, storing the number of threads per core. So, if `smt_supported == 1`, it means that there is 1 thread per core, and SMT is not supported. If SMT is supported, then `smt_supported >= 1`. Note this field tells if the CPU if supports it, but not if SMT is activated or not.
+- `smt_available`: The same idea as `smt_supported`, but it stores if SMT is available. If SMT is not supported, then `smt_available` is always `1`. The differentiation between supported and available lets cpufetch distinguish when a CPU has SMT capabilities, but are disabled (probably in the BIOS).
+
+Let's give two CPU examples and the values that `struct topology` would have in these CPUs.
+- Example 1: Dual Socket Intel Xeon 6248:
+
+```
+total_cores = 80
+physical_cores = 20
+logical_cores = 40
+smt_available = 2
+smt_supported = 2
+sockets = 2
+```
+
+- Example 2: Intel Core i7-4790K with SMT disabled in BIOS:
+
+```
+total_cores = 8
+physical_cores = 4
+logical_cores = 8
+smt_available = 1
+smt_supported = 2
+sockets = 1
+```
+
+Now that we know what data are we looking for, let's see how we get it:
+
+- __Intel__: The methodology used is explained in the Intel webpage [[2](#references)]. Intel explains how to do it and also gives an example source code. I used it and modified it to fit cpufetch style. The core of this methodology is the usage of the APIC id, so the code is inside __apic.c__.
+- __AMD__: Intel's algorithm using APIC does not work for AMD. To get the same information in AMD, I used the reference from OSdev [[3](#references)] and also ideas from lscpu [[4](#references)]. This uses:
+  - CPUID extended leaf 0x8: Fill `logical_cores`
+  - CPUID extended leaf 0x1E: Fill `smt_supported`
+  - CPUID standard leaf 0x1 (APIC): Fill `smt_available`
+
+  If any of these levels are not supported, these fields are just guessed. For example, if we are not able to know if SMT is supported, we guess it is not. With all of these data, we can calculate the rest of the fields:
+
+  ```
+  physical_cores = logical_cores / smt_available;  
+  if(topo->smt_supported > 1)
+    sockets = total_cores / smt_supported / physical_cores; // Idea borrowed from lscpu
+  else
+    sockets = total_cores / physical_cores;    
+  ```
+
+### 7. How to get cache topology?
+__Involved code: [get_cache_topology_amd (cpuid.c)](https://github.com/Dr-Noob/cpufetch/blob/master/src/x86/cpuid.c), [apic.c](https://github.com/Dr-Noob/cpufetch/blob/master/src/x86/apic.c)__
+
+The topology of a cache gives us information about how many caches we have at a given level. It usually follows the rule of:
+- L1: The same as the number of cores (one L1i and one L1d per core).
+- L2: If L2 is the last level cache, one L2. If not, the same as the number of cores (one L2 per core).
+- L3: One L3 cache per socket (shared among all cores).
+
+These assumptions are generally (but not always) true. For example, for the AMD Zen generation, or the Intel Xeon Phi KNL. Thus, cpufetch does not assume the topology but obtains it instead.
+
+- __Intel__: The idea is similar to the mentioned in CPU topology [[2](#references)](it also covers how to get cache topology using APIC id).
+
+- __AMD__: Again, we have to look for another path for AMD. This time, the way to do it is easier and (I think) more solid and future proof. The idea is to use extended CPUID leaf 0x1D. If the CPU does not support it, we can still guess the topology of the caches (as mentioned earlier). If it does, CPUID can give us how many cores shares a given level of cache. So, if we have the number of cores, we can guess how many caches are there for any given level (see __get_cache_topology_amd__).

+# cpufetch programming documentation (v0.98)
+This documentation explains how cpufetch works internally and all the design decisions I made. This document intends to be useful for me in the future, for everyone interested in the project, and for anyone who is trying to obtain any specific information from the CPU. In this way, this can be used as a manual or a page that collects interesting material in this area.
+
+### 1. Basics
+cpufetch works for __x86_64__ (Intel and AMD),  __ARM__ and __PowerPC__ CPUs. However, cpufetch is expected to work better on x86_64, because the codebase is older and has been tested much more than the ARM and PowerPC versions. Depending on the architecture, cpufetch choose certain files to be compiled. A summarized tree of the source code of cpufetch is shown below.
+
+```

+
+Source code is divided into four directories:
+
+- `common/`: Source code shared between all architectures
+- `arm/`: ARM source code
+- `ppc/`: PowerPC source code
+- `x86/`: x86 source code
+
+##### 1.1 Basics (x86_64)
+
+In x86, __cpufetch works using the CPUID instruction__. It is called directly using assembly (see `src/x86/cpuid_asm.c`). To understand how CPUID works, see [DOCUMENTATION_X86.md](https://github.com/Dr-Noob/cpufetch/blob/master/doc/DOCUMENTATION_X86.md).
+
+At the beginning of execution, cpufetch needs to know the max standard CPUID level and max CPUID extended level supported in the running CPU. We also need to know if the x86 CPU is Intel or AMD because sometimes, the way to obtain the information depends on the manufacturer. This information will be stored in:
+
+```
+struct cpuInfo {
+  ...
+  VENDOR cpu_vendor;
+  uint32_t maxLevels;  
+  uint32_t maxExtendedLevels;
+  ...
+};
+```
+
+To use any CPUID leaf, cpufetch always needs to check that it is supported in the current CPU.
+
+##### 1.2 Basics (ARM)
+In ARM, __cpufetch works using the MIDR register and Linux filesystem__. MIDR (Main ID Register) is read from `/proc/cpuinfo`. It allows the detection of the microarchitecture of the cores. Furthermore, Linux filesystem `/sys/devices/system/cpu/` is used to fetch the number of cores and other information. This is the main reason to explain __why `cpufetch` for ARM only works on Linux systems.__
+
+##### 1.3 Basics (PowerPC)
+In PowerPC, __cpufetch works using the PVR register and Linux filesystem__. PVR (Processor Version Register) is read using assembly and it is used to identify the microarchitecture of the CPU. Linux is also used to query the rest of the information, like the CPU topology, frequency, etc. This is the main reason to explain __why `cpufetch` for PowerPC only works on Linux systems.__
+
+##### 1.4 Documentation organization
+The rest of the documentation is divided in specific files for each architecture, since each one needs different implementations:

+ *              the color in ascii_logo->color_ascii[N]
+ * CR:          Color reset, gets replaced by the reset
+ *              color by printer.c
+ *
+ * Logos with replace_blocks=true are replaced by character
+ * blocks (actually, spaces with background color), so
+ * the color in the structure must be C_BG_XXX. When
+ * replace_blocks is true, the characters '#' are replaced
+ * by spaces printed with color_ascii[0], and '@' are
+ * printed with color_ascii[1]. If replace_blocks=true,
+ * color format specified in ASCIIs ($C1, $C2) are ignored.
+ *
+ * In any case, '$' is a illegal character to be used in
+ * the ascii logos because it is used to parse colors
+ *
+ * LONG_LOGOS will be printed only if the fit in the screen,
+ * otherwise SHORT_LOGOS will be used

+// and IA-32 Architectures Software Developer's Manual Combined Volumes: 1, 2A,
+// 2B, 2C, 2D, 3A, 3B, 3C, 3D, and 4" (the name changes from version to version
+// as more volumes are added).  The table moves around from version to version,
+// but in version 071US, was in "Volume 4: Model-Specific Registers", Table 2-1:
+// "CPUID Signature Values of DisplayFamily_DisplayModel".
+
+// MRG* is a table that forms the bulk of Intel Microcode Revision Guidance (or
+// Microcode Update Guidance).  Its purpose is not to list CPUID values, but
+// it does so, and sometimes lists values that appear nowhere else.
+
+// LX* indicates features that I have seen no documentation for, but which are
+// used by the Linux kernel (which is good evidence that they're correct).
+// The "hook" to find these generally is an X86_FEATURE_* flag in:
+//    arch/x86/include/asm/cpufeatures.h
+// For (synth) and (uarch synth) decoding, it often indicates
+// family/model/stepping value which are documented nowhere else.  These usually
+// can be found in:
+//    arch/x86/include/asm/intel-family.h
