Konstantin Belousov 32a1e9e4a5 Update print_INTEL_TLB() by the tag values from the Intel SDM ... rev. 55. The modern CPUs cache and TLB descriptions looked quite questionable without the update, e.g. Haswell i7 4770S reported: Data TLB: 4 KB pages, 4-way set associative, 64 entries L2 cache: 256 kbytes, 8-way associative, 64 bytes/line After the update, the report is: Data TLB: 1 GByte pages, 4-way set associative, 4 entries Data TLB: 4 KB pages, 4-way set associative, 64 entries Instruction TLB: 2M/4M pages, fully associative, 8 entries Instruction TLB: 4KByte pages, 8-way set associative, 64 entries 64-Byte prefetching Shared 2nd-Level TLB: 4 KByte/2MByte pages, 8-way associative, 1024 entries L2 cache: 256 kbytes, 8-way associative, 64 bytes/line Some tags were apparently removed from the table 3-21, Vol. 2A. Keep them around, but add a comment stating the removal. Update the format line for cpu_stdext_feature according to the bits from the SDM rev.55. It appears that Haswells do not store %cs and %ds values in the FPU save area. Store content of the %ecx register from the CPUID leaf 0x7 subleaf 0 as cpu_stdext_feature2 and print defined bits from it, again acording to SDM rev. 55.
