drm/amdgpu: set completion status as preempted for the resubmission

The driver's CSA buffer is shared by all the ibs. When the high priority ib
is submitted after the preempted ib, CP overrides the ib_completion_status
as completed in the csa buffer. After that the preempted ib is resubmitted,
CP would clear some locals stored for ib resume when reading the completed
status, which causes gpu hang in some cases.

Always set status as preempted for those resubmitted ib instead of reading
everything from the CSA buffer.

drm/ssd130x: Allocate buffer in the plane's .atomic_check() callback

Drivers are not allowed to fail after drm_atomic_helper_swap_state() has
been called and the new atomic state is stored into the current sw state.

Since the struct ssd130x_device .data_array is allocated in the encoder's
.atomic_enable callback, the operation can fail and this is after the new
state has been stored. So it can break an atomic mode settings assumption.

Fix this by having custom helpers to allocate, duplicate and destroy the
plane state, that will take care of allocating and freeing these buffers.

drm/omapdrm: Use GEM mmap for fbdev emulation

The fbdev emulation currently uses fbdev's default mmap code, which
has been written for I/O memory. Provide an mmap that uses GEM's mmap
infrastructure.

Utilize fine-grained fbdev macros to initialize struct fb_ops. The
macros set the read/write and the draw callbacks for DMA memory. Set
the fb_mmap callback to omapdrm's new mmap helper. Also select the
correct Kconfig token for fbdev's DMA helpers. Note that the DMA
helpers are the same as for system memory.

15 months agodrm/omapdrm: Set VM flags in GEM-object mmap function
Thomas Zimmermann [Fri, 7 Jul 2023 08:31:59 +0000 (10:31 +0200)]
drm/omapdrm: Set VM flags in GEM-object mmap function

Use the mmap callback in struct drm_gem_object_funcs to set the
VM flags. Replace a number of mmap helpers in omapdrm with their
GEM helper counterparts. Generate DRM's file-operations instance
with GEM's DEFINE_DRM_GEM_FOPS.

The omapdrm driver uses DRM's drm_gem_mmap() helper to prepare
the VMA structure. It then modifies the resulting VMA state in
its own helper omap_gem_mmap_obj(). The patch improves this by
setting up the VMA in the mmap callback in drm_gem_object_funcs,
which is called from within drm_gem_mmap().

Omapdrm's omap_gem_mmap() and omap_gem_mmap() can then be removed
from the driver. A call to drm_gem_mmap() is sufficient for the
mmap operation.

Finally, with the omap functions gone, the drivers file_ops in
omapdriver_fops can be generated with DEFINE_DRM_GEM_FOPS, which
sets DRM's default helpers.
