Now version 8 Note that linux-kernel@xxxxxxxxxxxxxxx and x86@xxxxxxxxxx are still dropped from the distribution. Time to get some internal agreement on these changes before bothering the x86 maintainers with yet another version. So I'm still 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 v7 Parts 1 & 2: Added "Reviewed-by" tag from Jarkko (Thanks!!!) Part 3: Jarkko had many good questions about the debugfs interface that was included to display addresses of pages on the SGX poison list. I don't have good answers to them all. While this was a useful hook while I was testing these patches (check that all the thousands of SGX pages that into which I had injected errors showed up on the list) it isn't needed for basic recovery. So I dropped the debugfs bits from the patch. We can revisit later when there is a clear use case for what should be provided. Parts 4-7: Unchanged. Tony Luck (7): x86/sgx: Add new sgx_epc_page flag bit to mark in-use 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/main.c | 104 +++++++++++++++++- arch/x86/kernel/cpu/sgx/sgx.h | 6 +- drivers/acpi/apei/einj.c | 3 +- drivers/acpi/apei/ghes.c | 2 +- include/linux/mm.h | 14 +++ mm/memory-failure.c | 19 +++- 9 files changed, 168 insertions(+), 11 deletions(-) base-commit: 5816b3e6577eaa676ceb00a848f0fd65fe2adc29 -- 2.31.1
