A corrupted storage partition table can make recovery impossible. A new partition with a pre-defined size, covering the entire storage, should replace partitions detected from the storage when the card is in survivability mode to allow a full memory update. This series intended to be merged via drm tree for consistency and requires ack from MTD maintainer. Signed-off-by: Alexander Usyskin --- Changes in v2: - Replace usual partitions with survivability one instead of adding addition partition to avoid problems with two partitons pointing to the same memory area. - The change is in the mtd part; Miquel, I feel that this requires re-review/ack from your side. - Link to v1: https://lore.kernel.org/r/20260715-cri_surviv-v1-0-61763a6f1076@intel.com --- Alexander Usyskin (2): mtd: mtd_intel_dg: add survivability partition drm/xe/nvm: define survivabilty partition drivers/gpu/drm/xe/xe_nvm.c | 13 ++++++-- drivers/mtd/devices/mtd_intel_dg.c | 66 +++++++++++++++++++++++++++++--------- include/linux/intel_dg_nvm_aux.h | 1 + 3 files changed, 61 insertions(+), 19 deletions(-) --- base-commit: baafc300cd079a5210c1e70e5ea3d93518e40b38 change-id: 20260715-cri_surviv-5a6faf7586f1 Best regards, -- Alexander Usyskin ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
