Subject: [PATCH 00/16] xen/arm: mm: Remove open-coding mappings
Date: Fri, 20 May 2022 13:09:21 +0100	[thread overview]
Message-ID: <20220520120937.28925-1-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)

Cheers,

[1] <20201119190751.22345-1-julien@xen.org>

Julien Grall (15):
  xen/arm: mm: Allow other mapping size in xen_pt_update_entry()
  xen/arm: mm: Add support for the contiguous bit
  xen/arm: mm: Avoid flushing the TLBs when mapping are inserted
  xen/arm: mm: Don't open-code Xen PT update in remove_early_mappings()
  xen/arm: mm: Re-implement early_fdt_map() using map_pages_to_xen()
  xen/arm32: mm: Re-implement setup_xenheap_mappings() using
    map_pages_to_xen()
  xen/arm: mm: Allocate xen page tables in domheap rather than xenheap
  xen/arm: mm: Allow page-table allocation from the boot allocator
  xen/arm: Move fixmap definitions in a separate header
  xen/arm: mm: Clean-up the includes and order them
  xen/arm: mm: Use the PMAP helpers in xen_{,un}map_table()
  xen/arm32: setup: Move out the code to populate the boot allocator
  xen/arm64: mm: Add memory to the boot allocator first
  xen/arm: mm: Rework setup_xenheap_mappings()
  xen/arm: mm: Re-implement setup_frame_table_mappings() with
    map_pages_to_xen()
