Cheers,
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() Wei Liu (1): xen/arm: add Persistent Map (PMAP) infrastructure xen/arch/arm/Kconfig | 1 + xen/arch/arm/acpi/lib.c | 2 + xen/arch/arm/include/asm/config.h | 6 - xen/arch/arm/include/asm/early_printk.h | 1 + xen/arch/arm/include/asm/fixmap.h | 48 +++ xen/arch/arm/include/asm/lpae.h | 8 + xen/arch/arm/include/asm/mm.h | 4 - xen/arch/arm/include/asm/page.h | 8 + xen/arch/arm/include/asm/pmap.h | 32 ++ xen/arch/arm/kernel.c | 1 + xen/arch/arm/mm.c | 494 +++++++++++++----------- xen/arch/arm/setup.c | 141 +++---- xen/common/Kconfig | 3 + xen/common/Makefile | 1 + xen/common/pmap.c | 72 ++++ xen/include/xen/acpi.h | 18 +- xen/include/xen/pmap.h | 16 + 17 files changed, 549 insertions(+), 307 deletions(-) create mode 100644 xen/arch/arm/include/asm/fixmap.h create mode 100644 xen/arch/arm/include/asm/pmap.h create mode 100644 xen/common/pmap.c create mode 100644 xen/include/xen/pmap.h
