Changelog:
v6:
- Don't optimise page range walk in the event of a double MMU fault
- Handle some minots and minor style changes
- Rebase patch series onto latest drm-misc-next
v5:
- Move devfreq record keeping further down job submission function to
keep busy count balanced in case of an early bail-out.
- In MMU page fault ISR, bail out when sgt for 2MiB page is not assigned,
rather than when the page array is populated. Add new commit for this.
- Add commit with myself as a new Panfrost maintainer
v4:
- Rebased older patch series onto latest drm-misc-next
- Added patch for renaming JM functions to reflect their actual role
- Fixed treatment of error code in perfcnt when enabling sample buffer AS
v3:
- Minor convenience fixes to patches 3 and 4 in the series
- Move unmapping of maped range of BO to the function's error path
in case of BO mapping failure, also for putting BO's pages
- Split patch 6/8 into two: one makes sure the Job IRQ enablement mask
isn't recalculated at every device reset and uses the same expression
everywhere in the driver, and another one that breaks the enablement
function into two stages.
v2:
- Removed commit that provided an explicit fence cleanup function
- Added commit for removing unused Panfrost device structure member
- Refactored how optional job interrupt reenabling during reset is handled
- Make the way errors and successful return values are delivered from inside
panfrost_mmu_as_get more according to standard.
- Simplify unmapping of already mapped area when mapping the pages of a BO
- Fixing management of runtime-PM reference counts when failing HW job
submission.
