2024-04-22drm/buddy: Implement tracking clear page featureArunpravin Paneer Selvam
- Add tracking clear page feature. - Driver should enable the DRM_BUDDY_CLEARED flag if it successfully clears the blocks in the free path. On the otherhand, DRM buddy marks each block as cleared. - Track the available cleared pages size - If driver requests cleared memory we prefer cleared memory but fallback to uncleared if we can't find the cleared blocks. when driver requests uncleared memory we try to use uncleared but fallback to cleared memory if necessary. - When a block gets freed we clear it and mark the freed block as cleared, when there are buddies which are cleared as well we can merge them. Otherwise, we prefer to keep the blocks as separated. - Add a function to support defragmentation. v1: - Depends on the flag check DRM_BUDDY_CLEARED, enable the block as cleared. Else, reset the clear flag for each block in the list(Christian) - For merging the 2 cleared blocks compare as below, drm_buddy_is_clear(block) != drm_buddy_is_clear(buddy)(Christian) - Defragment the memory beginning from min_order till the required memory space is available. v2: (Matthew) - Add a wrapper drm_buddy_free_list_internal for the freeing of blocks operation within drm buddy. - Write a macro block_incompatible() to allocate the required blocks. - Update the xe driver for the drm_buddy_free_list change in arguments. - add a warning if the two blocks are incompatible on defragmentation - call full defragmentation in the fini() function - place a condition to test if min_order is equal to 0 - replace the list with safe_reverse() variant as we might remove the block from the list. v3: - fix Gitlab user reported lockup issue. - Keep DRM_BUDDY_HEADER_CLEAR define sorted(Matthew) - modify to pass the root order instead max_order in fini() function(Matthew) - change bool 1 to true(Matthew) - add check if min_block_size is power of 2(Matthew) - modify the min_block_size datatype to u64(Matthew) v4: - rename the function drm_buddy_defrag with __force_merge. - Include __force_merge directly in drm buddy file and remove the defrag use in amdgpu driver. - Remove list_empty() check(Matthew) - Remove unnecessary space, headers and placement of new variables(Matthew) - Add a unit test case(Matthew) v5: - remove force merge support to actual range allocation and not to bail out when contains && split(Matthew) - add range support to force merge function. v6: - modify the alloc_range() function clear page non merged blocks allocation(Matthew) - correct the list_insert function name(Matthew).

2024-04-19drm/i915/dp: Fix DSC line buffer depth programmingImre Deak
Fix the calculation of the DSC line buffer depth. This is limited both by the source's and sink's maximum line buffer depth, but the former one was not taken into account. On all Intel platform's the source's maximum buffer depth is 13, so the overall limit is simply the minimum of the source/sink's limit, regardless of the DSC version. This leaves the DSI DSC line buffer depth calculation as-is, trusting VBT. On DSC version 1.2 for sinks reporting a maximum line buffer depth of 16 the line buffer depth was incorrectly programmed as 0, leading to a corruption in color gradients / lines on the decompressed screen image.

2024-04-15drm/panic: Add drm panic lockingDaniel Vetter
Rough sketch for the locking of drm panic printing code. The upshot of this approach is that we can pretty much entirely rely on the atomic commit flow, with the pair of raw_spin_lock/unlock providing any barriers we need, without having to create really big critical sections in code. This also avoids the need that drivers must explicitly update the panic handler state, which they might forget to do, or not do consistently, and then we blow up in the worst possible times. It is somewhat racy against a concurrent atomic update, and we might write into a buffer which the hardware will never display. But there's fundamentally no way to avoid that - if we do the panic state update explicitly after writing to the hardware, we might instead write to an old buffer that the user will barely ever see. Note that an rcu protected deference of plane->state would give us the the same guarantees, but it has the downside that we then need to protect the plane state freeing functions with call_rcu too. Which would very widely impact a lot of code and therefore doesn't seem worth the complexity compared to a raw spinlock with very tiny critical sections. Plus rcu cannot be used to protect access to peek/poke registers anyway, so we'd still need it for those cases. Peek/poke registers for vram access (or a gart pte reserved just for panic code) are also the reason I've gone with a per-device and not per-plane spinlock, since usually these things are global for the entire display. Going with per-plane locks would mean drivers for such hardware would need additional locks, which we don't want, since it deviates from the per-console takeoverlocks design. Longer term it might be useful if the panic notifiers grow a bit more structure than just the absolute bare EXPORT_SYMBOL(panic_notifier_list) - somewhat aside, why is that not EXPORT_SYMBOL_GPL ... If panic notifiers would be more like console drivers with proper register/unregister interfaces we could perhaps reuse the very fancy console lock with all it's check and takeover semantics that John Ogness is developing to fix the console_lock mess. But for the initial cut of a drm panic printing support I don't think we need that, because the critical sections are extremely small and only happen once per display refresh. So generally just 60 tiny locked sections per second, which is nothing compared to a serial console running a 115kbaud doing really slow mmio writes for each byte. So for now the raw spintrylock in drm panic notifier callback should be good enough. Another benefit of making panic notifiers more like full blown consoles (that are used in panics only) would be that we get the two stage design, where first all the safe outputs are used. And then the dangerous takeover tricks are deployed (where for display drivers we also might try to intercept any in-flight display buffer flips, which if we race and misprogram fifos and watermarks can hang the memory controller on some hw). For context the actual implementation on the drm side is by Jocelyn and this patch is meant to be combined with the overall approach in v7 (v8 is a bit less flexible, which I think is the wrong direction): https://lore.kernel.org/dri-devel/20240104160301.185915-1-jfalempe@redhat.com/ Note that the locking is very much not correct there, hence this separate rfc. Starting from v10, I (Jocelyn) have included this patch in the drm_panic series, and done the corresponding changes. v2: - fix authorship, this was all my typing - some typo oopsies - link to the drm panic work by Jocelyn for context v10: - Use spinlock_irqsave/restore (John Ogness) v11: - Use macro instead of inline functions for drm_panic_lock/unlock (John Ogness) Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Jocelyn Falempe <jfalempe@redhat.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: "Peter Zijlstra (Intel)" <peterz@infradead.org> Cc: Lukas Wunner <lukas@wunner.de> Cc: Petr Mladek <pmladek@suse.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: John Ogness <john.ogness@linutronix.de> Cc: Sergey Senozhatsky <senozhatsky@chromium.org> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: David Airlie <airlied@gmail.com> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240409163432.352518-2-jfalempe@redhat.com Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2024-04-11drm: Introduce plane SIZE_HINTS propertyVille Syrjälä
Add a new immutable plane property by which a plane can advertise a handful of recommended plane sizes. This would be mostly exposed by cursor planes as a slightly more capable replacement for the DRM_CAP_CURSOR_WIDTH/HEIGHT caps, which can only declare a one size fits all limit for the whole device. Currently eg. amdgpu/i915/nouveau just advertize the max cursor size via the cursor size caps. But always using the max sized cursor can waste a surprising amount of power, so a better strategy is desirable. Most other drivers don't specify any cursor size at all, in which case the ioctl code just claims that 64x64 is a great choice. Whether that is actually true is debatable. A poll of various compositor developers informs us that blindly probing with setcursor/atomic ioctl to determine suitable cursor sizes is not acceptable, thus the introduction of the new property to supplant the cursor size caps. The compositor will now be free to select a more optimal cursor size from the short list of options. Note that the reported sizes (either via the property or the caps) make no claims about things such as plane scaling. So these things should only really be consulted for simple "cursor like" use cases. Userspace consumer in the form of mutter seems ready: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3165 v2: Try to add some docs v3: Specify that value 0 is reserved for future use (basic idea from Jonas) Drop the note about typical hardware (Pekka) v4: Update the docs to indicate the list is "in order of preference" Add a a link to the mutter MR v5: Limit to cursors only for now (Simon) Cc: Jonas Ådahl <jadahl@redhat.com> Cc: Sameer Lattannavar <sameer.lattannavar@intel.com> Reviewed-by: Sebastian Wick <sebastian.wick@redhat.com> Reviewed-by: Simon Ser <contact@emersion.fr> Acked-by: Daniel Stone <daniels@collabora.com> Acked-by: Harry Wentland <harry.wentland@amd.com> Acked-by: Pekka Paalanen <pekka.paalanen@collabora.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240318204408.9687-2-ville.syrjala@linux.intel.com

2024-03-28drm/display: Make DisplayPort CEC-over-AUX Kconfig name consistentMaxime Ripard
While most display helpers Kconfig symbols have the DRM_DISPLAY prefix, the DisplayPort CEC tunnelling implementation uses CONFIG_DRM_DISPLAY_DP_AUX_CEC. Since the number of users is limited, we can easily rename it to make it consistent.

2024-03-26drm/dp: Clarify that wait_hpd_asserted() is not optional for panelsDouglas Anderson
In response to my patch removing the "wait for HPD" logic at the beginning of the MSM DP transfer() callback [1], we had some debate about what the "This is an optional function" meant in the documentation of the wait_hpd_asserted() callback. Let's clarify. As talked about in the MSM DP patch [1], before wait_hpd_asserted() was introduced there was no great way for panel drivers to wait for HPD in the case that the "built-in" HPD signal was used. Panel drivers could only wait for HPD if a GPIO was used. At the time, we ended up just saying that if we were using the "built-in" HPD signal that DP AUX controllers needed to wait for HPD themselves at the beginning of their transfer() callback. The fact that the wait for HPD at the beginning of transfer() was awkward/problematic was the whole reason wait_hpd_asserted() was added. Let's make it obvious that if a DP AUX controller implements wait_hpd_asserted() that they don't need a loop waiting for HPD at the start of their transfer() function. We'll still allow DP controllers to work the old way but mark it as deprecated.
