Dr-Noob	4229e2c63b	[v1.01][X86] Do not assume that cach and topo structures are non-NULL, which may easily happen in VMs. Add protection against NULL fields in cpu structure	2021-12-03 23:15:23 +01:00

Dr-Noob	fe3bc6163c	[v1.01] Do not use FMA for frequency measurement. It is sufficient to run any other AVX instructions, and some CPUs support AVX but not FMA.	2021-11-20 10:25:36 +01:00
Dr-Noob	4b50740516	[v1.01] Remove useless frequency measurement (SSE and novector should report the same frequency!). Increase iterations to improve precision	2021-11-20 10:13:35 +01:00

Dr-Noob	bb12a2c276	[v1.00] Fix ambiguity in uarch detection with 0x806E9; it may be Amber/Kaby Lake (thanks to #122 for pointing this out!). We can differentiate by CPU name (hacky, but is there a better way?)	2021-10-07 22:37:29 +02:00

Dr-Noob	3928a9e3b6	[v1.00] Ice Lake is NOT a uarch; Sunny Cove is. But we need to check for codename in these cases since with the uarch is not enough to determine the number of VPUs	2021-09-25 22:03:22 +02:00
