2022-06-24drm: shmobile: Use backlight helperStephen Kitt1-5/+1
This started with work on the removal of backlight_properties' deprecated fb_blank field, much of which can be taken care of by using helper functions provided by backlight.h instead of directly accessing fields in backlight_properties. This patch series doesn't involve fb_blank, but it still seems useful to use helper functions where appropriate. Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes.

2022-06-24drm/panel: panel-asus-z00t-tm5p5-n35596: Use backlight helperStephen Kitt1-6/+1
backlight_properties.fb_blank is deprecated. The states it represents are handled by other properties; but instead of accessing those properties directly, drivers should use the helpers provided by backlight.h. Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes.

Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes. Instead of setting the power state by manually updating fields in struct backlight_properties, use backlight_enable() and backlight_disable(). These also call backlight_update_status() so the separate call is no longer needed.

2022-06-24drm/panel: sony-acx565akm: Use backlight helpersStephen Kitt1-10/+2
Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes. Instead of manually checking the power state in struct backlight_properties, use backlight_is_blank(). While we're at it, drop .fb_blank from the initialisation function; it is deprecated, and this helps make progress towards enabling its removal. This change makes no functional difference since FB_BLANK_UNBLANK is the default value.

2022-06-23Revert "drm/amd/display: ignore modifiers when checking for format support"Bas Nieuwenhuizen1-46/+7
This reverts commit 5089c4a8ebea3c3ad9eedf038dad7098ebc06131. This breaks validation and enumeration of display capable modifiers. The early return true means the rest of the validation code never gets executed, and we need that to enumerate the right modifiers to userspace for the format. The modifiers that are in the initial list generated for a plane are the superset for all formats and we need the proper checks in this function to filter some of them out for formats with which they're invalid to be used. Furthermore, the safety contract here is that we validate the incoming modifiers to ensure the kernel can handle them and the display hardware can handle them. This includes e.g. rejecting multi-plane images with DCC. Note that the legacy swizzle mechanism allows encoding more swizzles, and at fb creation time we convert them to modifiers and reject those with no corresponding modifiers. If we are seeing rejections I'm happy to help define modifiers that correspond to those, or if absolutely needed implement a fallback path to allow for less strict validation of the legacy path. However, I'd like to revert this patch, since any of these is going to be a significant rework of the patch, and I'd rather not the regression gets into a release or forgotten in the meantime.

When the last reference of a gem object is removed it is added to the mm.free_list list and mm.free_work is queued to actually free the object. So gem objects that had their last reference removed by display during drm_atomic_helper_shutdown() are added to mm.free_list what could cause that mm.free_work is executed at the same time as intel_runtime_pm_driver_release() causing raw-wakerefs warning. So here only calling i915_gem_suspend() and by consequence i915_gem_drain_freed_objects() only after display is down making sure all display gem objecs are freed when intel_runtime_pm_driver_release() is executed.

2022-06-23drm/msm/dpu: Increment vsync_cnt before waking up userspaceStephen Boyd1-1/+2
The 'vsync_cnt' is used to count the number of frames for a crtc. Unfortunately, we increment the count after waking up userspace via dpu_crtc_vblank_callback() calling drm_crtc_handle_vblank(). drm_crtc_handle_vblank() wakes up userspace processes that have called drm_wait_vblank_ioctl(), and if that ioctl is expecting the count to increase it won't. Increment the count before calling into the drm APIs so that we don't have to worry about ordering the increment with anything else in drm. This fixes a software video decode test that fails to see frame counts increase on Trogdor boards.

2022-06-22drm/i915/gt: Re-do the intel-gtt splitLucas De Marchi9-734/+714
Re-do what was attempted in commit 7a5c922377b4 ("drm/i915/gt: Split intel-gtt functions by arch"). The goal of that commit was to split the handlers for older hardware that depend on intel-gtt.ko so i915 can be built for non-x86 archs, after some more patches. Other archs do not need intel-gtt.ko. Main issue with the previous approach: it moved all the hooks, including the gen8, which is used by all platforms gen8 and newer. Re-do the split moving only the handlers for gen < 6, which are the only ones calling out to the separate module. While at it do some minor cleanups: - Rename the prefix s/gen5_/gmch_/ to be more accurate what platforms are covered by intel_ggtt_gmch.c - Remove dead code for gen12 out of needs_idle_maps() - Remove TODO comment leftover - Re-order if/else ladder in ggtt_probe_hw() to keep newest platforms first v2: Add minor cleanups (Matt Roper) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Acked-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220617230559.2109427-2-lucas.demarchi@intel.com

2022-06-22drm/amdgpu: Adjust logic around GTT size (v3)Alex Deucher1-6/+14
Certain GL unit tests for large textures can cause problems with the OOM killer since there is no way to link this memory to a process. This was originally mitigated (but not necessarily eliminated) by limiting the GTT size. The problem is this limit is often too low for many modern games so just make the limit 1/2 of system memory. The OOM accounting needs to be addressed, but we shouldn't prevent common 3D applications from being usable just to potentially mitigate that corner case. Set default GTT size to max(3G, 1/2 of system ram) by default. v2: drop previous logic and default to 3/4 of ram v3: default to half of ram to align with ttm v4: fix spelling in comment (Kent) Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1942 Reviewed-by: Marek Olšák <marek.olsak@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
