Boris, I took this series out of lkml/x86 for a few revisions, I think the last one posted to lkml was v5. So much has changed since then that it might be easier to just look at this as if it were v1 and ignore the earlier history. First four patches add infrastructure within the SGX code to track enclave pages (because these pages don't have a "struct page" as they aren't directly accessible by Linux). All have "Reviewed-by" tags from Jarkko (SGX maintainer). Patch 5 hooks into memory_failure() to invoke recovery if the physical address is in enclave space. This has a "Reviewed-by" tag from Naoya Horiguchi the maintainer for mm/memory-failure.c Patch 6 is a hook into the error injection code and addition to the error injection documentation explaining extra steps needed to inject into SGX enclave memory. Patch 7 is a hook into GHES error reporting path to recognize that SGX enclave addresses are valid and need processing. -Tony Tony Luck (7): x86/sgx: Add new sgx_epc_page flag bit to mark free pages x86/sgx: Add infrastructure to identify SGX EPC pages x86/sgx: Initial poison handling for dirty and free pages x86/sgx: Add SGX infrastructure to recover from poison x86/sgx: Hook arch_memory_failure() into mainline code x86/sgx: Add hook to error injection address validation x86/sgx: Add check for SGX pages to ghes_do_memory_failure() .../firmware-guide/acpi/apei/einj.rst | 19 +++ arch/x86/Kconfig | 1 + arch/x86/include/asm/processor.h | 8 ++ arch/x86/include/asm/set_memory.h | 4 + arch/x86/kernel/cpu/sgx/main.c | 113 +++++++++++++++++- arch/x86/kernel/cpu/sgx/sgx.h | 7 +- drivers/acpi/apei/einj.c | 3 +- drivers/acpi/apei/ghes.c | 2 +- include/linux/mm.h | 13 ++ mm/memory-failure.c | 19 ++- 10 files changed, 179 insertions(+), 10 deletions(-) base-commit: 3906fe9bb7f1a2c8667ae54e967dc8690824f4ea -- 2.31.1
