2025-03-03drm/i915: relocate intel_plane_ggtt_offset() to intel_atomic_plane.cJani Nikula
With the primary goal of removing #include "i915_vma.h" from intel_display_types.h, move intel_plane_ggtt_offset() to a proper function in intel_atomic_plane.c. This reveals tons of implicit dependencies all over the place that we pulled in via i915_vma.h. Fix the fallout.

2025-03-02drm/rockchip: vop2: use devm_regmap_field_alloc for cluster-regsAndy Yan
Right now vop2_cluster_init() copies the base vop2_cluster_regs and adapts the reg value with the current window's offset before adding the fields to the regmap. This conflicts with the notion of reg_fields being const, see https://lore.kernel.org/all/20240706-regmap-const-structs-v1-1-d08c776da787@weissschuh.net/ for reference, which now causes checkpatch to actually warn about that. So instead of creating one big copy and changing it afterwards, add the reg_fields individually using devm_regmap_field_alloc().

In preparation for adding support for MT8195's HDMI reserved DPI, add calls to clk_prepare_enable() / clk_disable_unprepare() for the TVD clock: in this particular case, the aforementioned clock is not (and cannot be) parented to neither pixel or engine clocks hence it won't get enabled automatically by the clock framework. Please note that on all of the currently supported MediaTek platforms, the TVD clock is always a parent of either pixel or engine clocks, and this means that the common clock framework is already enabling this clock before the children. On such platforms, this commit will only increase the refcount of the TVD clock without any functional change.

2025-03-02drm/mediatek: mtk_dpi: Add support for DPI input clock from HDMIAngeloGioacchino Del Regno
On some SoCs, like MT8195 and MT8188, the DPI instance that is reserved to the HDMI Transmitter uses a different clock topology. In this case, the DPI is clocked by the HDMI IP, and this outputs its clock to the MM input of dpi_pixel_clk, which is essential to enable register access to the DPI IP. Add a `clocked_by_hdmi` member to struct mtk_dpi_conf, and check it to avoid enabling the DPI clocks in the mediatek-drm internal .start() callback (and avoid disabing in the .stop() component callback): this will make sure that the clock configuration sequence is respected during display pipeline setup by following the bridge ops between DPI and HDMI, where the HDMI driver is expected to enable the clocks in the bridge's pre_enable(), and DPI in the enable() cb.

In preparation for adding support for the DPI IP found in MT8195 and in MT8188 used for HDMI, move the code flow for calculation and setting of the DPI pixel clock to a separate function called mtk_dpi_set_pixel_clk().

2025-03-02drm/mediatek: mtk_dpi: Use an array for pixclk factor calculationAngeloGioacchino Del Regno
Setting the TVD PLL clock requires to multiply the target pixel clock by a specific constant factor to achieve the target PLL frequency, and this is done to reduce jitter to acceptable levels. On all MediaTek SoCs, the factor is not retrieved by any real kind of calculation but rather by checking if the target pixel clock is less than a specified frequency, hence assigning a function pointer for just a bunch of if branches does enlarge the code size for little reason. Remove all SoC-specific functions, add a structure `mtk_dpi_factor` that holds a clock frequency and corresponding PLL factor, and declare the constraints for each SoC in form of an array of said structure. Instead of function pointers, this structure (and its size) is then assigned to each SoC's platform data. The "calculation" is then performed with a new static function mtk_dpi_calculate_factor(dpi, mode_clk) that iterates through all of the entries of the aforementioned array and returns the right factor. If no factor is found, the lowest possible factor is returned, mimicking the same flow as all of the old per-SoC calculation functions. This commit brings no functional change.

2025-03-02drm/mediatek: mtk_dpi: Add support for Pattern Generator in debugfsAngeloGioacchino Del Regno
This IP includes a Pattern Generator which is useful for debugging and testing purposes: add the relevant register and bits to the mtk_dpi_regs.h header, and implement support for it in mtk_dpi. Adding this required to introduce a .debugfs_init() callback for the DPI bridge, which creates a "dpi_test_pattern" file in the directory of the appropriate connector. The pattern generator can generate various internal patterns and this submission includes support for: - 256 or 1024 shades of gray in a Vertical or Horizontal Pattern - Vertical Color Bars - Frame border - Dot Moire This generator also supports filling the entire screen with one custom color, but support for that is not included in this commit. Enabling and disabling this generator can be done by sending a string to the dpi_test_pattern debugfs file; the pattern is expected to be formatted as follows: <enable (1) or disable (0)> <pattern number> where the pattern number can be a number from 0 to 7, excluding 5. Of course 5 is excluded because that activates custom color fill which, again, is not supported in this commit.

2025-02-28drm/xe: Fix GT "for each engine" workaroundsTvrtko Ursulin
Any rules using engine matching are currently broken due RTP processing happening too in early init, before the list of hardware engines has been initialised. Fix this by moving workaround processing to later in the driver probe sequence, to just before the processed list is used for the first time. Looking at the debugfs gt0/workarounds on ADL-P we notice 14011060649 should be present while we see, before: GT Workarounds 14011059788 14015795083 And with the patch: GT Workarounds 14011060649 14011059788 14015795083 Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@igalia.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: stable@vger.kernel.org # v6.11+ Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250227101304.46660-2-tvrtko.ursulin@igalia.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>

2025-02-28drm/i915/display: Use explicit base values in POWER_DOMAIN_*() macrosGustavo Sousa
Although we have comments in intel_display_limits.h saying that the code expects PIPE_A and TRANSCODER_A to be zero, it doesn't hurt to add them as explicit base values for calculating the power domain offset in POWER_DOMAIN_*() macros. On the plus side, we have that this: * Fixes a warning reported by kernel test robot <lkp@intel.com> about doing arithmetic with two different enum types. * Makes the code arguably more robust (in the unlikely event of those bases becoming non-zero). v2: - Prefer using explicit base values instead of simply casting the macro argument to int. (Ville) - Update commit message to match the new approach (for reference, the old message subject was "drm/i915/display: Use explicit cast in POWER_DOMAIN_*() macros").

2025-02-28drm/i915/display: Use IP version check for Wa_14020863754Gustavo Sousa
Wa_14020863754 applies to the display IP, so we should be checking on display IP version instead of platform. So, let's replace display->platform.battlemage with the proper IP version check (14.01 for Xe2_HPD). Furthermore, for workarounds, we should be checking on full IP versions to avoid applying the workaround to some variant of the IP that could theoretically appear in the future (which is likely to have a different minor release number), since the issue addressed by the workaround could be fixed in such new release.

2025-02-28drm/xe/vf: Retry sending MMIO request to GUC on timeout errorSatyanarayana K V P
Add support to allow retrying the sending of MMIO requests from the VF to the GUC in the event of an error. During the suspend/resume process, VFs begin resuming only after the PF has resumed. Although the PF resumes, the GUC reset and provisioning occur later in a separate worker process. When there are a large number of VFs, some may attempt to resume before the PF has completed its provisioning. Therefore, if a MMIO request from a VF fails during this period, we will retry sending the request up to GUC_RESET_VF_STATE_RETRY_MAX times, which is set to a maximum of 10 attempts.

When both PF and VF devices are enabled on the host, they resume simultaneously during system resume. However, the PF must finish provisioning the VF before any VFs can successfully resume. Establish a parent-child device link between the PF and VF devices to ensure the correct order of resumption. V4 -> V5: - Added missing break in the error condition. V3 -> V4: - Made xe_pci_pf_get_vf_dev() as a static function and updated input parameter types. - Updated xe_sriov_warn() to xe_sriov_abort() when VF device cannot be found. V2 -> V3: - Added function documentation for xe_pci_pf_get_vf_dev(). - Added assertion if not called from PF.
