Subject: [PATCH v3 0/2] Parse out event records
Date: Sat, 28 Sep 2024 00:51:41 +0000 [thread overview]
Message-ID: <20240928005143.2378938-1-praan@google.com> (raw)
Enhance the arm-smmu-v3 driver to parse out useful information from
event records into a structure for better event handling & logging.
v3
* Fixed a potential race and null pointer deref for arm_smmu_master
* Improved the logging approach by using multiple strings
* Added logs for STAG & STALL fields for relevant events
* Invoked the log function within `arm_smmu_handle_evt` routine
* Rebased the changes
v2
https://lore.kernel.org/linux-iommu/20240827193026.3993039-1-praan@google.com/
* Addressed review comments
* Introduced `struct arm_smmu_event` to hold relevant event fields
* Broke out helper functions to populate & dump event info
* Modified the event handler routines to use `struct arm_smmu_event`
v1
