Subject: [PATCH v2 00/10] x86/resctrl: Misc cleanup
Date: Thu, 30 Apr 2020 18:03:50 +0100	[thread overview]
Message-ID: <20200430170400.21501-1-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, but not arch_needs_linear.

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 v5.7-rc3.

Thanks,

James
