Subject: [PATCH v4 13/13] drm/xe/xe_pci_error: Process errors in mmio_enabled
Date: Fri, 17 Apr 2026 14:28:25 +0530 [thread overview]
Message-ID: <20260417085812.4013309-28-riana.tauro@intel.com> (raw)
In-Reply-To: <20260417085812.4013309-15-riana.tauro@intel.com>
Query system controller when any non fatal error occurs to check
the type of the error, contain and recover.
The system controller is queried in the mmio_enabled callback.
Signed-off-by: Riana Tauro <riana.tauro@intel.com>

v2: use ras recovery enum (Raag)
v3: add comment for mapping
use const (Mallesh)
