[PATCH v2 0/2] drm/xe/nvm: add survivabilty partiton
From: Alexander Usyskin
Date: Wed Sep 16 2026 - 09:58:59 EST
One of the reasons for the CRI to enter survivability mode
is corrupted storage.
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.

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@xxxxxxxxx
