[PATCH v10 0/6] drm/imx: Introduce i.MX8qm/qxp DPU DRM
by Liu Ying 07 Apr '22

07 Apr '22

Hi, This is the v10 series to introduce i.MX8qm/qxp Display Processing Unit(DPU) DRM support. DPU is comprised of a blit engine for 2D graphics, a display controller and a command sequencer. Outside of DPU, optional prefetch engines can fetch data from memory prior to some DPU fetchunits of blit engine and display controller. The pre-fetchers support linear formats and Vivante GPU tile formats. Reference manual can be found at: https://www.nxp.com/webapp/Download?colCode=IMX8DQXPRM This patch set adds kernel modesetting support for the display controller part. It supports two CRTCs per display controller, several planes, prefetch engines and some properties of CRTC and plane. Currently, the registers of the controller is accessed without command sequencer involved, instead just by using CPU. DRM connectors would be created from the DPU KMS driver. Patch 1 ~ 3 add dt-bindings for DPU and prefetch engines. Patch 4 is a minor improvement of a macro to suppress warning as the KMS driver uses it. Patch 5 introduces the DPU DRM support. Patch 6 updates MAINTAINERS. Welcome comments, thanks. v9->v10: * Rebase the series upon v5.18-rc1. * Make 'checkpatch.pl --strict' happier for patch 5/6. * Add Rob's R-b tag on patch 3/6. * Add Laurentiu's R-b tag on patch 5/6. * Add Laurentiu's A-b tag on patch 6/6. v8->v9: * Use drm_atomic_get_new_plane_state() in dpu_plane_atomic_update() for patch 5/6. (Laurentiu) * Drop getting DPU DT alias ID for patch 5/6, as it is unused. * Reference 'interrupts-extended' schema instead of 'interrupts' for patch 3/6 to require an additional DPR interrupt(r_rtram_stall) because the reference manual does mention it, though the driver doesn't get/use it for now. Reference 'interrupt-names' schema to define the two DPR interrupt names - 'dpr_wrap' and 'r_rtram_stall'. Accordingly, patch 5/6 gets the 'dpr_wrap' interrupt by name. * Drop Rob's R-b tag on patch 3/6, as review is needed. v7->v8: * Rebase this series up onto the latest drm-misc-next branch, due to DRM plane helper functions API change(atomic_check and atomic_update) from DRM atomic core. So, dpu_plane_atomic_check() and dpu_plane_atomic_update() are updated accordingly in patch 5/6. Also, rename plane->state variables and relevant DPU plane state variables in those two functions to reflect they are new states, like the patch 'drm: Rename plane->state variables in atomic update and disable' recently landed in drm-misc-next. * Replace drm_gem_fb_prepare_fb() with drm_gem_plane_helper_prepare_fb() in patch 5/6, due to DRM core API change. * Improve DPR burst length for GPU standard tile and 32bpp GPU super tile in patch 5/6 to align with the latest version of internal HW documention. v6->v7: * Fix return value of dpu_get_irqs() if platform_get_irq() fails. (Laurentiu) * Use the function array dpu_irq_handler[] to store individual DPU irq handlers. (Laurentiu) * Call get/put() hooks directly to get/put DPU fetchunits for DPU plane groups. (Laurentiu) * Shorten the names of individual DPU irq handlers by using DPU unit abbrev names to make writing dpu_irq_handler[] easier. * Add Rob's R-b tag back on DPU dt-binding patch as change in v6 was reviewed. v5->v6: * Use graph schema in the DPU dt-binding. * Do not use macros where possible in the DPU DRM driver. (Laurentiu) * Break dpu_plane_atomic_check() into some smaller functions. (Laurentiu) * Address some minor comments from Laurentiu on the DPU DRM driver. * Add dpu_crtc_err() helper marco in the DPU DRM driver to tell dmesg which CRTC generates error. * Drop calling dev_set_drvdata() from dpu_drm_bind/unbind() in the DPU DRM driver as it is done in dpu_drm_probe(). * Some trivial tweaks. v4->v5: * Rebase up onto the latest drm-misc-next branch and remove the hook to drm_atomic_helper_legacy_gamma_set() from patch 5/6, because it was dropped by the newly landed commit 'drm: automatic legacy gamma support'. * Remove a redundant blank line from dpu_plane_atomic_update() in patch 5/6. v3->v4: * Improve compatible properties in DPU and prefetch engines' dt bindings by using enum instead of oneOf+const. * Add Rob's R-b tags on dt binding patches(patch 1/6, 2/6 and 3/6). * Add Daniel's A-b tag on patch 4/6. v2->v3: * Fix DPU DRM driver build warnings which are Reported-by: kernel test robot <lkp(a)intel.com>. * Drop DPU DRM driver build dependency on IMX_SCU, as dummy SCU functions have been added in header files by the patch 'firmware: imx: add dummy functions' which has landed in linux-next/master branch. * Add a missing blank line in include/drm/drm_atomic.h. v1->v2: * Test this patch set also with i.MX8qm LVDS displays. * Drop the device tree patches because we'll use new dt binding way to support i.MX8qm/qxp clocks. This depends on a not-yet-landed patch set to do basic conversions for the platforms. * Fix dt binding yamllint warnings. * Require bypass0 and bypass1 clocks for both i.MX8qxp and i.MX8qm in DPU's dt binding documentation. * Use new dt binding way to add clocks in the dt binding examples. * Address several comments from Laurentiu on the DPU DRM patch.

[PATCH] stm: ltdc: fix two incorrect NULL checks on list iterator
by Xiaomeng Tong 07 Apr '22

07 Apr '22

The two bugs are here: if (encoder) { if (bridge && bridge->timings) The list iterator value 'encoder/bridge' will *always* be set and non-NULL by drm_for_each_encoder()/list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the list is empty or no element is found. To fix the bug, use a new variable '*_iter' as the list iterator, while use the old variable 'encoder/bridge' as a dedicated pointer to point to the found element.

[PATCH] drm/atomic: Convert a warning to dbg atomic printk
by Zack Rusin 07 Apr '22

07 Apr '22

From: Zack Rusin <zackr(a)vmware.com> By default each flip times out after 0.1 sec and a warning about the time out is added to the kernel log. The warning is harmless because there's another flip coming right after but it can quickly fill up the log, e.g. missing 2 flips every second over a 24 hour span will add about 172 thousand lines to the log. Skip printing it by default and instead add it to the atomic drm debug category. It can be trivially enabled via drm.debug=0x10 and it avoids filling up logs by default. This is particularly important on vm's where presentation might be CPU bound and running multiple vm's or under a CPU heavy load can easily lead to missing mutliple flips and any actual errors are often blamed on this due to it being so prevalent in the logs. Fixes a bunch of bugs reported to RedHat (1792515, 1884401, 1896139 and 1884401) and SUSE (210123) where people complain about having their logs spammed by this message and blame various errors on it.

[PATCH] drm/i915: consider min_page_size when migrating

We can only force migrate an object if the existing object size is compatible with the new destinations min_page_size for the region.

[PATCH v4] drm/atomic-helpers: remove legacy_cursor_update hacks
by Maxime Ripard 07 Apr '22

07 Apr '22

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> The stuff never really worked, and leads to lots of fun because it out-of-order frees atomic states. Which upsets KASAN, among other things. For async updates we now have a more solid solution with the ->atomic_async_check and ->atomic_async_commit hooks. Support for that for msm and vc4 landed. nouveau and i915 have their own commit routines, doing something similar. For everyone else it's probably better to remove the use-after-free bug, and encourage folks to use the async support instead. The affected drivers which register a legacy cursor plane and don't either use the new async stuff or their own commit routine are: amdgpu, atmel, mediatek, qxl, rockchip, sti, sun4i, tegra, virtio, and vmwgfx. Inspired by an amdgpu bug report. v2: Drop RFC, I think with amdgpu converted over to use atomic_async_check/commit done in commit 674e78acae0dfb4beb56132e41cbae5b60f7d662 Author: Nicholas Kazlauskas <nicholas.kazlauskas(a)amd.com> Date: Wed Dec 5 14:59:07 2018 -0500 drm/amd/display: Add fast path for cursor plane updates we don't have any driver anymore where we have userspace expecting solid legacy cursor support _and_ they are using the atomic helpers in their fully glory. So we can retire this. v3: Paper over msm and i915 regression. The complete_all is the only thing missing afaict. v4: Rebased on recent kernel, added extra link for vc4 bug.
