Subject: [PATCH v2 0/5] eagerfpu patches for tip/x86/fpu
Date: Mon, 10 Sep 2012 11:11:00 -0700 [thread overview]
Message-ID: <1347300665-6209-1-git-send-email-suresh.b.siddha@intel.com> (raw)
v2 version of the previous patchset https://lkml.org/lkml/2012/9/7/548
that decouples eagerfpu into a synthetic cpuid feature.
changes from v1:
* Made "eagerfpu=" boot parameter tri-state
* removed the cpu_has_xmm check in the fx_finit (not related to eagerfpu
per-say, but this patchset touches that area of code).
Suresh Siddha (5):
x86, fpu: decouple non-lazy/eager fpu restore from xsave
x86, fpu: enable eagerfpu by default for xsaveopt
x86, fpu: move check_fpu() after alternative_instructions()
x86, fpu: make eagerfpu= boot param tri-state
x86, fpu: remove cpu_has_xmm check in the fx_finit()
