Subject: [PATCH 0/2] arch/x86: Enable MPK feature on AMD
Date: Wed, 06 May 2020 17:02:05 -0500 [thread overview]
Message-ID: <158880240546.11615.2219410169137148044.stgit@naples-babu.amd.com> (raw)
AMD's next generation of EPYC processors support the MPK (Memory
Protection Keys) feature.
AMD documentation for MPK feature is available at "AMD64 Architecture
Programmer’s Manual Volume 2: System Programming, Pub. 24593 Rev. 3.34,
Section 5.6.6 Memory Protection Keys (MPK) Bit".
The documentation can be obtained at the link below:
https://bugzilla.kernel.org/show_bug.cgi?id=206537
This series enables the feature on AMD and updates config parameters
to reflect the MPK support on generic x86 platforms.
