[PATCH V2 0/3] dmaengine: idxd: Error path fixes

Posted by Reinette Chatre 1 year, 4 months ago

Changes since v1:
- V1: https://lore.kernel.org/lkml/cover.1670005163.git.reinette.chatre@intel.com/
- Cover trimmed after obtaining needed information.
- Added Reviewed-by tags.
- cc stable team.
- Please see individual patches for patch specific changes.

Dear Maintainers,

I have been using the IDXD driver to experiment with the upcoming core
changes in support of IMS ([1], [2], [3]). As part of this work I
happened to exercise the error paths within IDXD and encountered
a few issues that are addressed in this series. These changes are
independent from IMS and just aims to make the IDXD driver more
robust against errors.

Your feedback is greatly appreciated.

Reinette
