2013-10-06Add support for decoding cache information in cpuid.4HEADmasterSøren Sandmann Pedersen1-0/+59
When cpuid.2 reports a cache descriptor of 0xff, that means cpuid.2 doesn't contain any information about caches and that instead you are supposed to find this information in cpuid.4. This patch adds support for decoding that information.

This corresponds to an ITLB for 2M/4M pages with 8 entries.

2011-05-31lsmsr: Add support to show MSRs for which no description is providedAndreas Herrmann1-2/+6
Of course no verbose information but only the plain value of the register (if it's a valid MSR address) can be provided. Example: # lsmsr -r 0xdeadbeef -l warning: unknown MSR deadbeef unknown: 0xdeadbeef; (at your own risk) # lsmsr -r 0xdeadbeef warning: unknown MSR deadbeef could not read MSR 0xdeadbeef ((null)): Input/output error unknown = 0x0000000000000000 Artificial example (forcing use of family 0xf register description and showing PstateControl MSR on a family 0x10 CPU): # ./lsmsr -r 0xc0010062 -f 0xf warning: unknown MSR c0010062 unknown = 0x0000000000000003 Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com>

2011-04-05x86info, AMD: Update CPU revisionsAndreas Herrmann2-29/+16
Provide just a general model description for all family 10h CPUs. It's not possible to derive from model/family/stepping whether its an Phenom or Turion II etc. This information is provided in the processor name string. (It could be decoded from other CPUID information and with help of CPU revision guides but that's not yet implemented.) Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com>
2011-04-05x86info, AMD: powernow: Display boosted Pstate informationAndreas Herrmann2-14/+87
Fix output on systems with boosted Pstates. Indicate whether CPB is enabled. Display all Pstates (including the boosted ones). Example: Boosting enabled Number of boost states: 1 Pstate-Pb0: 3600MHz (boost state) Pstate-P0: 3200MHz (current) Pstate-P1: 2400MHz Pstate-P2: 1600MHz Pstate-P3: 800MHz In addition get rid of fid and vid information for HW Pstates. It's too CPU family specific. (Use lsmsr instead for this kind of information.) Note: this patch adds a new requirement to link x86info against libpci which usually is installed with pciutils (http://mj.ucw.cz/pciutils.html).

2011-04-05cpuid: Fix pointer arithmeticAndreas Herrmann1-4/+4
Commit 208fb9613c8c151b2885e89066a3eb22a977df6f (Fix up aliasing warnings.) changed pointer arithmetic in one part of cpuid function from - if (eax!=0) *eax = (*(unsigned *)(buffer )); - if (ebx!=0) *ebx = (*(unsigned *)(buffer+ 4)); - if (ecx!=0) *ecx = (*(unsigned *)(buffer+ 8)); - if (edx!=0) *edx = (*(unsigned *)(buffer+12)); + if (eax!=0) *eax = *(ptr)++; + if (ebx!=0) *ebx = *(ptr)++; + if (ecx!=0) *ecx = *(ptr)++; + if (edx!=0) *edx = *(ptr); The post-increment is not equal to what was used before. This causes generation of wrong cpuid information, e.g. lsmsr fails: $ ./lsmsr -a -l CPU not (yet) supported (vendor="(unknown)", family=16, model=10) Fix this by pre-incrementing the pointer before it is dereferenced.
