Subject: [Xen-devel] [PATCH v2 0/4] x86/microcode: Support builtin CPU microcode
Date: Wed, 18 Dec 2019 01:32:55 +0000	[thread overview]
Message-ID: <cover.1576630344.git.elnikety@amazon.com> (raw)

The main goal of this patch series is to add support for builtin microcode.
Towards that end, the series starts with a few improvements for the
documentation and parsing of the ucode= Xen command line parameter that
controls early loading of microcode (Patches 1--3), and follows with the
main builtin suppot (Patch 4).

Changes in v2:
- An earlier version of Patch 4 was submitted in isolation. Refer to the
  patch itself for details regarding the relevant changes.
- Patches 1--3 are additions.

Eslam Elnikety (4):
  x86/microcode: Improve documentation and parsing for ucode=
  x86/microcode: avoid unnecessary xmalloc/memcpy of ucode data
  x86/microcode: use const qualifier for microcode buffer
  x86/microcode: Support builtin CPU microcode
