We're doing a great job for really simple drivers right now, but still a lot of boilerplate for the bigger ones. Acked-by:

[Why] In hdmi_mode_alternate_clock(), it adds an exception for VIC 4 mode (4096x2160@24) due to there is no alternate clock defined for that mode in HDMI1.4b. But HDMI2.0 adds 23.98Hz for that mode. [How] Remove the exception v2: Adjust the comment description of hdmi_mode_alternate_clock() due to there is no more exception for VIC 4 mode. Signed-off-by:

[Why] HDMI 2.0 adds aspect ratio attribute to distinguish different 4k modes. According to Appendix E of HDMI 2.0 spec, source should use VSIF to indicate video mode only when the mode is one defined in HDMI 1.4b 4K modes. Otherwise, use AVI infoframes to convey VIC. Current code doesn't take aspect ratio into consideration while constructing avi infoframe. Should modify that. [How] Inherit Ville Syrjälä's work "drm/edid: Prep for HDMI VIC aspect ratio" at https://patchwork.kernel.org/patch/11174639/ Add picture_aspect_ratio attributes to edid_4k_modes[] and construct VIC and HDMI_VIC by taking aspect ratio into consideration. v2: Correct missing initializer error at adding aspect ratio of SMPTE mode.

Add selftests for drm_rect. A few basic ones for clipped and unclipped cases, and a few special ones for specific bugs we had in the code. I'm too lazy to think of more corner cases to check at this time. Maybe later. Signed-off-by:

Now that we've constrained the clipped source rectangle such that it can't have negative dimensions doing the same for the dst rectangle seems appropriate. Should at least result in the clipped src and dst rectangles being a bit more consistent with each other.

Limit the scaled clip to only clip at most dst_w/h pixels. This avoids the problem with clip_scaled() not being able to return negative values.

Problem: Due to a race between drm_sched_cleanup_jobs in sched thread and drm_sched_job_timedout in timeout work there is a possiblity that bad job was already freed while still being accessed from the timeout thread. Fix: Instead of just peeking at the bad job in the mirror list remove it from the list under lock and then put it back later when we are garanteed no race with main sched thread is possible which is after the thread is parked. v2: Lock around processing ring_mirror_list in drm_sched_cleanup_jobs. v3: Rebase on top of drm-misc-next. v2 is not needed anymore as drm_sched_get_cleanup_job already has a lock there. v4: Fix comments to relfect latest code in drm-misc.

Udl's custom implementation for struct drm_gem_object_funcs.free_object unmaps perma-mapped memory buffer before freeing the buffer object.

Udl keeps a BO mapped for its entire lifetime if it has been used in a damage update at least once. The BO's free callback release the mapping before it frees the BO. Change this behaviour to unmap immediately after the damage update, so SHMEM's implementation of free can be used. Signed-off-by:

It's unused. 10 years ago, back when 32bit was still fairly common and trying to not exhaust vmalloc space sounded like a worthwhile goal, adding these to dma_buf made sense. Reality is that they simply never caught on, and nowadays everyone who needs plenty of buffers will run in 64bit mode anyway. Also update the docs in this area to adjust them to reality. The actual hooks in dma_buf_ops will be removed once all the implementations are gone. Acked-by:

No in-tree users left. Note that this is one of the few (if only) implementations of dma-buf that provided a kmap, but not a vmap implemenation. Given that the only real user (in-tree at least) of kmap was tegra, and it's impossible to buy a chip with tegra host1x and ompadrm on the same SoC, there's no problem here. Acked-by:

There's no callers in-tree anymore. For merging probably best to stuff this into drm-misc, since that's where the dma-buf heaps will land too. And the resulting conflict hopefully ensures that dma-buf heaps wont have a new ->kmap/unmap implemenation. Acked-by:

It doesn't have any callers anymore. Aside: The ->mmap/munmap hooks have a bit a confusing name, they don't do userspace mmaps, but a kernel vmap. I think most places use vmap for this, except ttm, which uses kmap for vmap for added confusion. mmap seems entirely for userspace mappings set up through mmap(2) syscall. Reviewed-by:

Daniel Vetter authored
A few reasons to drop kmap: - For native objects all we do is look at obj->vaddr anyway, so might as well not call functions for every page. - Reloc-processing on dma-buf is ... questionable. - Plus most dma-buf that bother kernel cpu mmaps give you at least vmap, much less kmaps. And all the ones relevant for arm-soc are again doing a obj->vaddr game anyway, there's no real kmap going on on arm it seems. Plus this seems to be the only real in-tree user of dma_buf_kmap, and I'd like to get rid of that. Reviewed-by:
