| |
Hi Joerg,
Please pull these Arm SMMU updates for 5.5. The main changes are support for the Qualcomm SMMUv2 implementation in the SDM845 SoC using the recently introduced "implementation hook" code, a bunch of preparatory work to expose TTBR1 via the io-pgtable code so that two (distinct) page tables can be attached to a domain at the same time and performance improvements relating to runtime power management on SMMUv2 during unmap() and general dispatch of the new TLB invalidation callbacks.
The Qualcomm patches necessitated some changes to their firmware interface code, but that has been Acked by Andy and Bjorn.
There were some conflicts with the fixes I sent you previously, so this branch has those same commits merged in because I didn't want to rebase.
Cheers,
Will
