Linux kernel source tree

Some users of KVM have emulated devices (typically added to private forks of QEMU) that execute AVX instructions on PCI BARs. Whenever the guest OS tries to do that, an illegal instruction exception or emulation failure is triggered. Add the Avx flag to move instructions: - (66) 0f 10 - MOVUPS/MOVUPD from memory - (66) 0f 11 - MOVUPS/MOVUPD to memory - 66 0f 6f - MOVDQA from memory - 66 0f 7f - MOVDQA to memory - f3 0f 6f - MOVDQU from memory - f3 0f 7f - MOVDQU to memory - (66) 0f 28 - MOVAPS/MOVAPD from memory - (66) 0f 29 - MOVAPS/MOVAPD to memory - (66) 0f 2b - MOVNTPS/MOVNTPD to memory - 66 0f e7 - MOVNTDQ to memory - 66 0f 38 2a - MOVNTDQA to memory Co-developed-by: Keith Busch <kbusch@kernel.org> Signed-off-by: Keith Busch <kbusch@kernel.org> Link: https://lore.kernel.org/kvm/BD108C42-0382-4B17-B601-434A4BD038E7@fb.com/T/ Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Link: https://patch.msgid.link/20251114003633.60689-11-pbonzini@redhat.com Signed-off-by: Sean Christopherson <seanjc@google.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
