Add support for damage handling and deferred I/O to fbdev-dma. This enables fbdev-dma to support all DMA-memory-based DRM drivers, even such with a dirty callback in their framebuffers. The patch adds the code for deferred I/O and also sets a dedicated helper for struct fb_ops.fb_mmap that support coherent mappings. v3: - init fb_ops with FB_GEN_DEFAULT_DEFERRED_DMAMEM_OPS() (Javier) Signed-off-by:

Thomas Zimmermann authored
Add an fbdev emulation for SHMEM-based memory managers. The code is similar to fbdev-generic, but does not require an additional shadow buffer for mmap(). Fbdev-shmem operates directly on the buffer object's SHMEM pages. Fbdev's deferred-I/O mechanism updates the hardware state on write operations. The memory pages of GEM SHMEM cannot be detected by fbdefio. Therefore fbdev-shmem implements the .get_page() hook in struct fb_deferred_io. The fbdefio helpers call this hook to retrieve the page directly from fbdev-shmem instead of trying to detect it internally. v3: - clarify on get_page mechanism in commit description (Javier) v2: - use drm_driver_legacy_fb_format() (Geert) Signed-off-by:

Thomas Zimmermann authored
Add a callback for drivers to provide framebuffer pages to fbdev's deferred-I/O helpers. Implementations need to acquire a reference on the page before returning it. Returning NULL generates a SIGBUS signal. This will be useful for DRM's fbdev emulation with GEM-shmem buffer objects. v2: - fix typo in commit message (Javier) Signed-off-by:

Thomas Zimmermann authored
Unconditionally call get_page() after looking up a page from the framebuffer memory. Guarantees that we always hold a reference. This change also refactors the code such that it can support a driver-supplied get_page helper. This will be useful for DRM's fbdev emulation. Signed-off-by:

Thomas Zimmermann authored
Clean up the pageref state as part of the lastclose helper. This only requires to clear the page's mapping field. The pageref and page can stay in place for the next opened instance of the frame- buffer file. With the change in the clean-up logic, there's no further need to look up pages during the lastclose cleanup. The code instead uses the existing pagerefs in its look-up table. It also avoids using smem_len, which some driver might not set correctly. v2: - fix typos in commit message (Javier) Signed-off-by:

Thomas Zimmermann authored
Set up struct fb_deferred_io_pageref in the new helper function fb_deferred_io_pageref_lookup(), which runs when the pageref is first taken. Remove the setup code from the rest of the code. At first, the code allocates the memory of all pageref structs. The setup of the various fields happens when the pageref is required. v2: - fix typo in commit message (Javier) Signed-off-by:

Thomas Zimmermann authored
Framebuffer memory is allocated via vzalloc() from non-contiguous physical pages. The physical framebuffer start address is therefore meaningless. Do not set it. The value is not used within the kernel and only exported to userspace on dedicated ARM configs. No functional change is expected. v2: - refer to vzalloc() in commit message (Javier) Signed-off-by:

Having conditional around the of_node pointer of the drm_bridge structure is not necessary anymore, since drm_bridge structure always has the of_node member since the commit d8dfccde ("drm/bridge: Drop conditionals around of_node pointers"). So drop the conditional, please also note that this patch is following the convention used by driver core, see commit c9e358df ("driver-core: remove conditionals around devicetree pointers").

Merge tag 'drm-intel-gt-next-2024-04-26' of https://anongit.freedesktop.org/git/drm/drm-intel into drm-next UAPI Changes: - drm/i915/guc: Use context hints for GT frequency Allow user to provide a low latency context hint. When set, KMD sends a hint to GuC which results in special handling for this context. SLPC will ramp the GT frequency aggressively every time it switches to this context. The down freq threshold will also be lower so GuC will ramp down the GT freq for this context more slowly. We also disable waitboost for this context as that will interfere with the strategy. We need to enable the use of SLPC Compute strategy during init, but it will apply only to contexts that set this bit during context creation. Userland can check whether this feature is supported using a new param- I915_PARAM_HAS_CONTEXT_FREQ_HINT. This flag is true for all guc submission enabled platforms as they use SLPC for frequency management. The Mesa usage model for this flag is here - https://gitlab.freedesktop.org/sushmave/mesa/-/commits/compute_hint - drm/i915/gt: Enable only one CCS for compute workload Enable only one CCS engine by default with all the compute sices allocated to it. While generating the list of UABI engines to be exposed to the user, exclude any additional CCS engines beyond the first instance *** NOTE: This W/A will make all DG2 SKUs appear like single CCS SKUs by default to mitigate a hardware bug. All the EUs will still remain usable, and all the userspace drivers have been confirmed to be able to dynamically detect the change in number of CCS engines and adjust. For the smaller percent of applications that get perf benefit from letting the userspace driver dispatch across all 4 CCS engines we will be introducing a sysfs control as a later patch to choose 4 CCS each with 25% EUs (or 50% if 2 CCS). NOTE: A regression has been reported at https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/10895 However Andi has been triaging the issue and we're closing in a fix to the gap in the W/A implementation: https://lists.freedesktop.org/archives/intel-gfx/2024-April/348747.html Driver Changes: - Add new and fix to existing workarounds: Wa_14018575942 (MTL), Wa_16019325821 (Gen12.70), Wa_14019159160 (MTL), Wa_16015675438, Wa_14020495402 (Gen12.70) (Tejas, John, Lucas) - Fix UAF on destroy against retire race and remove two earlier partial fixes (Janusz) - Limit the reserved VM space to only the platforms that need it (Andi) - Reset queue_priority_hint on parking for execlist platforms (Chris) - Fix gt reset with GuC submission is disabled (Nirmoy) - Correct capture of EIR register on hang (John) - Remove usage of the deprecated ida_simple_xx() API - Refactor confusing __intel_gt_reset() (Nirmoy) - Fix the fix for GuC reset lock confusion (John) - Simplify/extend platform check for Wa_14018913170 (John) - Replace dev_priv with i915 (Andi) - Add and use gt_to_guc() wrapper (Andi) - Remove bogus null check (Rodrigo, Dan) .

After IGT migrating to dynamic sub-tests, the pipe prefixes in the expected fails list are incorrect. Lets drop those to accurately match the expected fails. In addition, update the xfails list to match the current passing list. This should have ideally failed in the CI run because some tests were marked as fail even though they passed but due to the mismatch in test names, the matching didn't correctly work and was resulting in those failures not being seen. Here is the passing pipeline for apq8016 with this change: https://gitlab.freedesktop.org/drm/msm/-/jobs/57050562Signed-off-by:

This reverts commit 8a91b29f. The regulator_disable() added by the original commit solves one kind of regulator imbalance but adds another one as it allows the regulator to be disabled one more time than it is enabled in the following scenario: 1. Start video pipeline -> sn65dsi83_atomic_pre_enable -> regulator_enable 2. PLL lock fails -> regulator_disable 3. Stop video pipeline -> sn65dsi83_atomic_disable -> regulator_disable The reason is clear from the code flow, which looks like this (after removing unrelated code): static void sn65dsi83_atomic_pre_enable() { regulator_enable(ctx->vcc); if (PLL failed locking) { regulator_disable(ctx->vcc); <---- added by patch being reverted return; } } static void sn65dsi83_atomic_disable() { regulator_disable(ctx->vcc); } The use case for introducing the additional regulator_disable() was removing the module for debugging (see link below for the discussion). If the module is removed after a .atomic_pre_enable, i.e. with an active pipeline from the DRM point of view, .atomic_disable is not called and thus the regulator would not be disabled. According to the discussion however there is no actual use case for removing the module with an active pipeline, except for debugging/development. On the other hand, the occurrence of a PLL lock failure is possible due to any physical reason (e.g. a temporary hardware failure for electrical reasons) so handling it gracefully should be supported. As there is no way for .atomic[_pre]_enable to report an error to the core, the only clean way to support it is calling regulator_disabled() only in .atomic_disable, unconditionally, as it was before.
