Subject: [PATCH RFCv2 00/15] xen/arm: mm: Remove open-coding mappings
Date: Sun, 25 Apr 2021 21:13:03 +0100 [thread overview]
Message-ID: <20210425201318.15447-1-julien@xen.org> (raw)
From: Julien Grall <jgrall@amazon.com>
Hi all,
This series was originally sent as "xen/arm: mm: Add limited support
for superpages" [1] and finally has grown enough to remove most of
the open-coding mappings in the boot code.
This will help to:
1) Get better compliance with the Arm memory model
2) Pave the way to support other page size (64KB, 16KB)
This is not fully finished (only boot tested on Arm64) but I sent it
early to get more testing and also unblock some of the on-going work
to support static memory allocation for dom0less (see [2]).
There are still a few TODOs:
- Add support for setting the contiguous bits
- Remove 1GB alignment in setup_xenheap_mappings()
- Decide whether we want to provide a common PMAP
Cheers,
[1] <20201119190751.22345-1-julien@xen.org>
