Now version 6 (what I actually meant to post as v5). Note that I've dropped linux-kernel@xxxxxxxxxxxxxxx and x86@xxxxxxxxxx from the distribution. Time to get some internal agreement on these changes before bothering the x86 maintainers with yet another version. So I'm looking for Acked-by: or Reviewed-by: on any bits of this series that are worthy, and comments on the problems I need to fix in the not-worthy parts. Changes since v4 (I'm going to ignore the bogus v5 I posted): Jarkko Sakkinen: + Add linux-sgx@xxxxxxxxxxxxxxx to Cc: list + Remove explicit struct sgx_va_page *va_page type from argument and use in sgx_alloc_va_page(). Just use "void *" as this code doesn't do anything with the internals of struct sgx_va_page. + Drop the union of all possible types for the "owner" field in struct sgx_epc_page (sorry Dave Hansen, this went in last time from your comment, but it doesn't seem to add much value). Back to "void *owner;" + rename the xarray that tracks which addresses are EPC pages from "epc_page_ranges" to "sgx_epc_address_space". Dave Hansen: + Use more generic names for the globally visible functions that are needed in generic code: sgx_memory_failure -> arch_memory_failure sgx_is_epc_page -> arch_is_platform_page + Commit comment on space used by xarray to track EPC pages. Tony Luck: + Found that ghes code spits warnings for memory addresses that it thinks are bad. Add a check for SGX pages. Tony Luck (7): x86/sgx: Provide indication of life-cycle of EPC 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/include/asm/processor.h | 8 + arch/x86/include/asm/set_memory.h | 4 + arch/x86/kernel/cpu/sgx/encl.c | 5 +- arch/x86/kernel/cpu/sgx/encl.h | 2 +- arch/x86/kernel/cpu/sgx/ioctl.c | 2 +- arch/x86/kernel/cpu/sgx/main.c | 137 ++++++++++++++++-- arch/x86/kernel/cpu/sgx/sgx.h | 7 +- drivers/acpi/apei/einj.c | 3 +- drivers/acpi/apei/ghes.c | 2 +- include/linux/mm.h | 14 ++ mm/memory-failure.c | 19 ++- 12 files changed, 196 insertions(+), 26 deletions(-) base-commit: e4e737bb5c170df6135a127739a9e6148ee3da82 -- 2.31.1
