Cover letter [PATCH 0/8] io-pgtable lock removal
Quoted 9 lines · Ray Jui
Hi Will/Robin,
Has anything functionally changed between PATCH v2 and v1? I'm seeing a very different L2 throughput with v2 (in general a lot worse with v2 vs. v1); however, I'm currently unable to reproduce the TLB sync timed out issue with v2 (without the patch from Will's email).
It could also be something else that has changed in my setup, but so far I have not yet been able to spot anything wrong in the setup.
There were fixes, and that initially involved a DSB that was found to be expensive. The patches queued in -next should have that addressed, so please use those (or my for-joerg/arm-smmu/updates branch).
Will
