Subject: [uml-devel] [PATCH 0/3] um: Add support for extended processor state
Date: Sun, 6 Mar 2016 22:36:24 +0800 [thread overview]
Message-ID: <1457274987-20078-1-git-send-email-elicooper@gmx.com> (raw)
This series adds support for the extended processor state (XSTATE) for
x86_64 UML, especially the YMM registers used by AVX/AVX2 instructions.
Modern userspace programs built with AVX can now run inside x86_64 UML
without YMM registers getting corrupted.
Eli Cooper (3):
um: extend _fpstate to _xstate
um: add extended processor state save/restore support
um: fix ptrace PTRACE_GETFPREGS and PTRACE_SETFPREG support
