This patch adds code to inject hwpoison into SGX memory. The SGX memory is processor reserved memory that cannot be directly accessed by system software. Changes since v2: - As suggested by Naoya Horiguchi <naoya.horiguchi@xxxxxxx>, add a new mf_action_page_type MF_MSG_SGX and use action_result() to show the page type and the action taken. - Rewrite hwpoison.rst to show the output from dmesg after injection. - Add reinette.chatre@xxxxxxxxx to the email list. Sorry that I mistyped the email address in the previous emails. - v2 Reviewed-by: Jarkko Sakkinen <jarkko@xxxxxxxxxx> Changes since v1: - Add a comment in hwpoison_inject as suggested by Miaohe - v1: Reviewed-by: Tony Luck <tony.luck@xxxxxxxxx> - v1: Reviewed-by: Miaohe Lin <linmiaohe@xxxxxxxxxx> Thomas Tai (1): x86/sgx: Add code to inject hwpoison into SGX memory Documentation/mm/hwpoison.rst | 24 ++++++++++++++++++++++++ include/linux/mm.h | 1 + include/ras/ras_event.h | 1 + mm/hwpoison-inject.c | 4 ++++ mm/memory-failure.c | 5 ++++- 5 files changed, 34 insertions(+), 1 deletion(-) -- 2 .31.1
