Subject: [PATCH v3 00/10] x86/resctrl: Misc cleanup
Date: Mon, 18 May 2020 14:19:13 +0100	[thread overview]
Message-ID: <20200518131924.7741-1-james.morse@arm.com> (raw)

Hello!

These are the miscellaneous cleanup patches that floated to the top of
the MPAM tree.

The only interesting thing are the patches to make the AMD/Intel
differences something resctrl understands, instead of just 'happening'
because of the different function pointers.
This will become more important once MPAM support is added. parse_bw()
and friends are what enforces resctrl's ABI resctrl. Allowing an
architecture/platform to provide a subtly different function here would
be bad for user-space.

MPAM would set arch_has_sparse_bitmaps and arch_has_empty_bitmap, but
not arch_needs_linear.


Since [v2], arch_has_empty_bitmap has been added, and some typos fixed.

Since [v1], I've picked up all the review feedback and collected the
tags.

Nothing in this series should change any behaviour.
This series is based on tip's x86/cache branch: v5.7-rc4-7-g0c4d5ba1b998
and can be retrieved from:
git://linux-arm.org/linux-jm.git mpam/cleanup/v3


Thanks,

James
