Subject: [PATCH 00/20] Initial support for small BAR recovery
Date: Wed, 26 Jan 2022 15:21:35 +0000	[thread overview]
Message-ID: <20220126152155.3070602-1-matthew.auld@intel.com> (raw)

Starting from DG2 we will have resizable BAR support for device local-memory,
but in some cases the final BAR size might still be smaller than the total
local-memory size. In such cases only part of local-memory will be CPU
accessible, while the remainder is only accessible via the GPU. This series adds
the basic enablers needed to ensure that the entire local-memory range is
usable.

Patches 1-3 are taken directly from Arun' in-progress series[1], which reworks
part of the allocator, and for example, allows us to allocate memory within a
sub-range, and is needed when allocating mappable memory. These patches are only
included here for the benefit of CI testing.
