Merge tag 'drm-msm-next-2021-07-28' of https://gitlab.freedesktop.org/drm/msm into drm-next

2021-07-30T06:24:01+00:00

An early pull for v5.15 (there'll be more coming in a week or two), consisting of the drm/scheduler conversion and a couple other small series that one was based one. Mostly sending this now because IIUC danvet wanted it in drm-next so he could rebase on it. (Daniel, if you disagree then speak up, and I'll instead include this in the main pull request once that is ready.) This also has a core patch to drop drm_gem_object_put_locked() now that the last use of it is removed.

drm/vma: Add a driver_private member to vma_node.

2021-06-11T08:53:18+00:00

This allows drivers to distinguish between different types of vma_node's. The readonly flag was unused and is thus removed. This is a temporary solution, until i915 is converted completely to use ttm for bo's.

drm: Set vm_ops to GEM object's values during mmap

2021-01-18T09:37:26+00:00

The GEM mmap code relies on the GEM object's mmap callback to set the VMA's vm_ops field. This is easily forgotten and already led to a memory leak in the CMA helpers. Instead set the vm_ops field in the DRM core code to the GEM object's value. Drivers with different needs can override this in their mmap callback. v2: * support (vm_ops == NULL) if mmap is given; required by VRAM helpers Signed-off-by: Thomas Zimmermann Fixes: f5ca8eb6f9bd ("drm/cma-helper: Implement mmap as GEM CMA object functions") Reviewed-by: Daniel Vetter Reported-by: Kieran Bingham Tested-by: Kieran Bingham Cc: Maxime Ripard Cc: Maarten Lankhorst Cc: David Airlie Cc: Daniel Vetter Cc: Eric Anholt Cc: dri-devel@lists.freedesktop.org Link: https://patchwork.freedesktop.org/patch/msgid/20210115093038.10345-1-tzimmermann@suse.de
