Subject: [PATCH 0/9] introduce mirrored memory support for arm64
Date: Sat, 26 Mar 2022 14:46:23 +0800 [thread overview]
Message-ID: <20220326064632.131637-1-mawupeng1@huawei.com> (raw)
From: Ma Wupeng <mawupeng1@huawei.com>
Commit b05b9f5f9dcf ("x86, mirror: x86 enabling - find mirrored memory ranges")
introduced mirrored memory support for x86. This support rely on UEFI to
report mirrored memory address ranges. See UEFI 2.5 spec pages 157-158:
http://www.uefi.org/sites/default/files/resources/UEFI%202_5.pdf
Arm64 can support this too. So mirrored memory support is added to support
arm64.
Patch #1-#2 introduce efi_fake_mem support for arm64.
Patch #3-#4 introduce mirrored memory support form arm64.
Patch #5-#7 fix some bugs for arm64 if memory reliable is enabled.
Patch #8 disable mirror feature if kernelcore is not specified.
Patch #9 remove some redundant code in ia64 efi_init.
Ma Wupeng (9):
efi: Make efi_print_memmap() public
arm64: efi: Add fake memory support
efi: Make efi_find_mirror() public
arm64/mirror: arm64 enabling - find mirrored memory ranges
mm: Ratelimited mirrored memory related warning messages
mm: Demote warning message in vmemmap_verify() to debug level
mm: Calc the right pfn if page size is not 4K
efi: Disable mirror feature if kernelcore is not specified
ia64/efi: Code simplification in efi_init
