Use new_*_state and old_*_state for their respective new/old DRM object states. Reviewed-by:
-
Leo (Sunpeng) Li authored
To conform to DRM's new API, we should not be accessing a DRM object's internal state directly. Rather, the DRM for_each_old/new_* iterators, and drm_atomic_get_old/new_* interface should be used. This is an ongoing process. For now, update the DRM-facing atomic functions, where the atomic state object is given. Reviewed-by:

Use the correct for_each_new/old_* iterators instead of for_each_* The following functions were considered: amdgpu_dm_find_first_crtc_matching_connector: use for_each_new - Old from_state_var flag was always choosing the new state amdgpu_dm_display_resume: use for_each_new - drm_atomic_helper_duplicate_state is called during suspend to cache the state - It sets 'state' within the state triplet to 'new_state' amdgpu_dm_commit_planes: use for_each_old - Called after the state was swapped (via atomic commit tail) amdgpu_dm_atomic_commit: use for_each_new - Called before the state is swapped amdgpu_dm_atomic_commit_tail: use for_each_old - Called after the state was swapped dm_update_crtcs_state: use for_each_new - Called before the state is swapped (via atomic check) amdgpu_dm_atomic_check: use for_each_new - Called before the state is swapped v2: Split out typo fixes to a new patch. v3: Say "functions considered" instead of "affected functions". The latter implies that changes are made to each. [airlied: squashed with my hacks] Reviewed-by: -

Initially we configured the PAD_CTRL1 register at probe/bind time. However it seems the HDMI controller will modify some of the bits in this register by itself. On the A10 it is particularly annoying as it toggles the output invert bits, which inverts the colors on the display output. The U-boot driver this driver is based on sets this register twice, though it seems it's only needed for actual display output. Hence we move it to the mode_set function. Signed-off-by:

While debugging inverted color from the HDMI output on the A10, I found that the lowest 3 bits were set. These were cleared on A20 boards that had normal display output. By manually toggling these bits the mapping of the color components to these bits was found. While these are not used anywhere, it would be nice to document them somewhere. Signed-off-by:

Many of the backend's layer configuration registers have undefined default values. This poses a risk as we use regmap_update_bits in some places, and don't overwrite the whole register. At probe/bind time we explicitly clear all the control registers by writing 0 to them. This patch adds a more detailed explanation on why we're doing this. Signed-off-by:

Commit 4636ce93 ("drm/fb-cma-helper: Add drm_fb_cma_get_gem_addr()") adds a new helper, which covers fetching a drm_framebuffer's GEM object and calculating the buffer address for a given plane. This patch uses this helper to replace our own open coded version of the same function. Signed-off-by:

The backend has various clocks and reset controls that need to be enabled and deasserted before register access is possible. Move the creation of the regmap to after the clocks and reset controls have been configured where it makes more sense. Signed-off-by:

Even though the components framework can handle duplicate entries, the extra entries cause a lot more debug messages to be generated, which would be confusing to developers not familiar with our driver and the framework in general. Instead, we can scan the relatively small queue and check if the component to be added is already queued up. Since the display pipelines are symmetrical (not considering the third display pipeline on the A80), and we add components level by level, when we get to the second instance at the same level, any shared downstream components would already be in the queue.

Most notable addition this time is the support for the GPU performance counters by Christian. This has been in the making for some time and it has matured a lot. Since this is adding UAPI, the corresponding WIP userspace can be found at [1] mesa/libdrm repos. I expect that Christian sends out the final userspace patches for this once you have pulled the kernel bits. Philipp optimized the probe path, so etnaviv gets out of the way for systems that want to boot real quick. I've done mostly cleanups, disentangling etnaviv from the IOMMU API, with some MMUv1 optimizations on the way. * 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux: (36 commits) drm/etnaviv: remove unnecessary clock stabilization delay drm/etnaviv: reduce reset delay drm/etnaviv: remove unused function etnaviv_gem_new drm/etnaviv: remove stale comment drm/etnaviv: submit supports performance monitor requests drm/etnaviv: enable debug registers on demand drm/etnaviv: need to disable clock gating when doing profiling drm/etnaviv: add MC perf domain drm/etnaviv: add TX perf domain drm/etnaviv: add RA perf domain drm/etnaviv: add SE perf domain drm/etnaviv: add PA perf domain drm/etnaviv: add SH perf domain drm/etnaviv: add PE perf domain drm/etnaviv: add HI perf domain drm/etnaviv: use 'sync points' for performance monitor requests drm/etnaviv: clear alloced event drm/etnaviv: add 'sync point' support drm/etnaviv: add performance monitor request processing drm/etnaviv: copy pmrs from userspace ...

Core drm shouldn't depend on anything in drm-kms-helper, or the drm module will fail to load. insmod drm fails with [ 6087.674390] drm: Unknown symbol drm_panel_bridge_remove (err 0) which is defined in drm_kms_helper.ko This call was added by commit c70087e8 ("drm/drm_of: add drm_of_panel_bridge_remove function"), and the fix is defining it in the drm_of.h header, to break the circular dependency.
