Subject: [PATCH v4 00/13] Introduce Xe Uncorrectable Error Handling
Date: Fri, 17 Apr 2026 14:28:12 +0530 [thread overview]
Message-ID: <20260417085812.4013309-15-riana.tauro@intel.com> (raw)
This series adds support for XE Uncorrectable Error Handling
The first four patches implement PCI error recovery callbacks for AER events.
On fatal errors, the device is wedged in error_detected and a Secondary
Bus reset (SBR) is requested from PCI core by returning
PCI_ERS_RESULT_NEED_RESET.
On non-fatal errors, the mmio_enabled callback is invoked to query the
error and attempt the required recovery.
This series adds support for handling Uncorrectable core compute,
SoC internal and device memory errors.
Core Compute Errors: Uncorrectable Core-Compute errors are classified
into Global and Local errors.
Global error is an error that affects the entire device requiring
a reset to recover. When an AER is reported and error_detected is invoked
return PCI_ERS_RESULT_NEED_RESET.
A Local error is confined to a specific component or context like a
engine. These errors can be contained and recovered by resetting
only the affected part without distrupting the rest of the device.
SoC Internal errors: Most of the uncorrectable SoC internal errors
are recovered using a SBR apart from CSC firmware and Punit errors.
CSC firmware errors requires a firmware flash to be recovered whereas
Punit error requires cold-reset.
Device memory errors: Most of the uncorrectable memory errors are
recovered using a SBR. However, Double-bit ECC error requires page
offlining for containment. Add helpers to instruct firmware to offline
page. Also add helpers to get pages offlined by firmware on module load.
The page offlining patch will be integrated after the patch
https://patchwork.freedesktop.org/series/161473/ is merged.
Rev2: Add support for SoC internal errors
fix review comments
Rev3: remove in_recovery flag for disconnect error
prevent sysctrl flooding
use minimal logging
simplify soc structures
add error_count to GT structures
Rev4: add device memory errors
add helpers for memory errors
fix cosmetic review comments
