f178de98f3 Fix issue #104: Intel Coffee Lake and Kaby Lake
Add support for detecting Coffee Lake i[357]s. Test included.
Thanks to @X0rg for reporting and to @exdeus for the raw cpu data.

The detection here relies on Kaby and Coffee lakes having different
number of cores for the equivalent brand:

i3: 2 cores in Kaby, 4 in Coffee
i5 and i7: 4 cores in Kaby, 6 in Coffee.

Along with some interop changes, as the Intel/AMD bits were sometimes
very similar or totally coinciding.

a196e8d1bf Related to #91: Add detection of AMD APUs.
It is very simple detection - if the brand string contains " APU ",
the _APU_ bit in amd_code_and_bits_t::bits is set.

Simplify one other line as well.

779b403aa0 Matchtable refactoring for AMD (see previous commit). 2017-03-20 01:47:28 +02:00
Veselin Georgiev
8179882abb Major refactoring of the Intel match tables.
There were a lot of instances where there was additional code
written to detect certain features from the brand string
(e.g., does it have "Core (TM)"? if it has, does it have "i3"?).
It makes sense to only write code for detecting these features
in isolation, preventing the exponential blowup of possible
intel_code_t values (e.g. previously there were enum values
for CORE_{,IVY,HASWELL,BROADWELL,SKYLAKE}{,M}{3,5,7} - almost
20 separate enums items; these can now be expressed with the
respective bits (CORE_, _I_, _M_, _3, _5 and _7).

The change in matchtables is the addition of an extra field
after brand_code: it is called model_bits. The bits for each
vendor is defined in the beginning of recog_<<vendor>>.c

This is the first part of the overhaul, which handles the bits
detection and proper matchtables for Intel. Refactoring of
AMD detection code coming next...

e36a08deb9 Fixed issue #76: Skylake Core i5 badly recognized
Add support for detecting RDSEED and ADX instructions.
Use RDSEED instead of RTM to ascertain that the CPU is
Broadwell or later in recog_intel.c. This fixes
detection discrepancies on Linux, where RTM is not
made available (I guess there's no kernel support for it).

The two new flags are also now detected in the Broadwell
and Skylake tests. Update them as well.
