Subject: [PATCH v3] arm64/mm: add fallback option to allocate virtually contiguous memory
Date: Wed, 14 Oct 2020 17:51:22 -0700 [thread overview]
Message-ID: <cover.1602722808.git.sudaraja@codeaurora.org> (raw)
V1: The initial patch used the approach to abort at the first instance of PMD_SIZE
allocation failure, unmaps all previously mapped sections using vmemmap_free
and maps the entire request with vmemmap_populate_basepages to allocate
virtually contiguous memory.
https://lkml.org/lkml/2020/9/10/66
V2: Allocates virtually contiguous memory only for sections that failed
PMD_SIZE allocation, and continous to allocate physically contiguous
memory for other sections.
https://lkml.org/lkml/2020/9/30/1489
V3: Addressed trivial review comments. Pass in altmap to vmemmap_populate_basepages.
