Subject: [patch V2 00/30] x86/fpu: Preparatory cleanups for AMX support (part 1)
Date: Fri, 15 Oct 2021 03:15:53 +0200 (CEST) [thread overview]
Message-ID: <20211015011411.304289784@linutronix.de> (raw)
This is the rework of the V1 part-1 series of the effort to support the new
AMX feature:
https://lore.kernel.org/r/20211011215813.558681373@linutronix.de
This part cleans up existing mess. Historical leftovers, shortcomings and
especially the universal kitchen sink asm/fpu/internal.h which is included
all over the place for the wrong reasons.
This series has a value independent of AMX, but allows to make the
integration and conversion to the new world order of dynamically enabled
feature bits simpler.
The serries is based on:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86/fpu
and also available from git:
git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git x86/fpu-1
The full series which has the full AMX support included can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git x86/fpu
Changes vs. V1:
- Fixed the issue in the !XSAVE code path of the kvm UABI copy function -
Paolo
- Renamed the KVM functions - Boris, Paolo, Sean
- Fixed the comments and changelog issues - Boris
Thanks,
tglx
