The post-migration recovery needs to be fully implemented for a specific platform in order to make continuation of workloads possible. New platforms introduce changes which affect the recovery procedure, and without a clear verification of support this leads to errors with no straight forward error message explaining the cause. This patch fixes that issue - it introduces a message to be logged when the current driver is known to not support the current platform. Wedging the driver immediately also decreases the amount of additional errors which would come afterwards if the driver continued operation. v2: Show the message during probe as well as during recovery; do not perform any recovery steps if the recovery is bound to fail v3: Use SRIOV-specific logging, fix typos v4: XE_DEBUG_SRIOV to XE_DEBUG check switch, to make testing more straightforward Signed-off-by: Tomasz Lis <tomasz.lis@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Acked-by: Michał Winiarski <michal.winiarski@intel.com> Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Link: https://lore.kernel.org/r/20250519230035.3143966-1-tomasz.lis@intel.com
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
