Subject: [PATCH v2 00/11] iommu/vt-d: Some Intel IOMMU cleanups
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
