[PATCH 0/3] Some SMMUv3 bug fixes

Posted by Eric Auger 3 years, 3 months ago

Hi,

This series fixes three issues:

- top SID computation overflow when handling SMMU_CMD_CFGI_ALL
- internal IOTLB handling (changes related to range invalidation)
  - smmu_iotlb_inv_iova with asid = -1
  - non power of 2 invalidation range handling.

Best Regards

Eric
