Hi folks,
After a long time of evolution, the drivers/iommu/intel/iommu.c becomes a bit messy. This series tries to cleanup and refactor the driver to make it more concise.
It includes,
- Remove some unnecessary code, includes and prototypes; - Move creating per-device driver data from domain_attach to device_probe callback. - Use an array for global per-device driver data so that they could be searched repidly. - Use the rculist for per-domain device driver data and remove the existing spinlock. - Code style fix.
Your comments are very appreciated.
Best regards, baolu
Change log:
v1: initial post - https://lore.kernel.org/linux-iommu/20220207064142.1092846-1-baolu.lu@linux.intel.com/
v2: - Avoid migration of large amounts of code. - Split the cleanup patches into separated ones for convenient code review. - This version of series is available on github: https://github.com/LuBaolu/intel-iommu/commits/iommu-vtd-cleanup-v2
