[ Upstream commit 04ae3eb470e52a3c41babe85ff8cee195e4dcbea ] When lima_vm_map_bo fails, the resources need to be deallocated, or there will be memleaks.

drm/lima: Fix opp clkname setting in case of missing regulator

2022-11-14T11:08:21+00:00

Commit d8c32d3971e4 ("drm/lima: Migrate to dev_pm_opp_set_config()") introduced a regression as it may undo the clk_names setting in case the optional regulator is missing. This resulted in test and performance regressions with lima. Restore the old behavior where clk_names is set separately so it is not undone in case of a missing optional regulator.

drm/lima: Migrate to dev_pm_opp_set_config()

The OPP core now provides a unified API for setting all configuration types, i.e. dev_pm_opp_set_config(). Lets start using it. Signed-off-by: Viresh Kumar

OPP: Make dev_pm_opp_set_regulators() accept NULL terminated list

2022-07-08T05:56:44+00:00

Make dev_pm_opp_set_regulators() accept a NULL terminated list of names instead of making the callers keep the two parameters in sync, which creates an opportunity for bugs to get in.

dma-buf: specify usage while adding fences to dma_resv obj v7

2022-04-07T10:53:53+00:00

Instead of distingting between shared and exclusive fences specify the fence usage while adding fences. Rework all drivers to use this interface instead and deprecate the old one. v2: some kerneldoc comments suggested by Daniel v3: fix a missing case in radeon v4: rebase on nouveau changes, fix lockdep and temporary disable warning v5: more documentation updates v6: separate internal dma_resv changes from this patch, avoids to disable warning temporary, rebase on upstream changes v7: fix missed case in lima driver, minimize changes to i915_gem_busy_ioctl Signed-off-by: Christian König Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20220407085946.744568-3-christian.koenig@amd.com

dma-buf/drivers: make reserving a shared slot mandatory v4

2022-04-06T15:38:25+00:00

Audit all the users of dma_resv_add_excl_fence() and make sure they reserve a shared slot also when only trying to add an exclusive fence. This is the next step towards handling the exclusive fence like a shared one. v2: fix missed case in amdgpu v3: and two more radeon, rename function v4: add one more case to TTM, fix i915 after rebase Signed-off-by: Christian König Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20220406075132.3263-2-christian.koenig@amd.com
