drm/v3d: fix a missing check of pm_runtime_get_sync

2019-04-01T17:45:59+00:00

pm_runtime_get_sync could fail and thus deserves a check. The patch adds such a check and return its error code upstream if it indeed failed.

drm/v3d: Rename the fence signaled from IRQs to "irq_fence".

2019-04-01T17:44:34+00:00

We have another thing called the "done fence" that tracks when the scheduler considers the job done, and having the shared name was confusing. Signed-off-by: Eric Anholt Link: https://patchwork.freedesktop.org/patch/msgid/20190313235211.28995-2-eric@anholt.net Reviewed-by: Dave Emett

drm/v3d: Add a note about OOM vs FLDONE, which may be racing on v3.3.

2019-04-01T17:44:27+00:00

We deref v3d->bin_job in the work handler, but v3d->bin_job doesn't actually hold a ref on the job. v2: typo fix FRDONE -> FLDONE Signed-off-by: Eric Anholt Link: https://patchwork.freedesktop.org/patch/msgid/20190313235211.28995-1-eric@anholt.net Reviewed-by: Dave Emett

drm/v3d: fix a NULL vs error pointer mixup

2019-04-01T16:33:38+00:00

The drm_gem_shmem_create() returns error pointers and v3d_bo_create() is also supposed to return error pointers.

drm/v3d: Use the new shmem helpers to reduce driver boilerplate.

2019-03-14T19:06:44+00:00

The new shmem helpers from Noralf and Rob abstract out a bunch of our BO creation and mapping code. v2: Use the new sgt getter, and flag pages as dirty before freeing. v3: Remove the mismatched put_pages.

drm/v3d: Add support for V3D v4.2.

2019-03-08T23:09:56+00:00

No compatible string for it yet, just the version-dependent changes. They've now tied the hub and the core interrupt lines into a single interrupt line coming out of the block. It also turns out I made a mistake in modeling the V3D v3.3 and v4.1 bridge as a part of V3D itself -- the bridge is going away in favor of an external reset controller in a larger HW module. v2: Use consistent checks for whether we're on 4.2, and fix a leak in an error path. v3: Use more general means of determining if the current 4.2 changes are in place, as apparently other platforms may switch back (noted by Dave). Update the binding doc. v4: Improve error handling for IRQ init.
