2021-03-24drm/rockchip: Remove unused variableMaxime Ripard
Commit 977697e20b3d ("drm/atomic: Pass the full state to planes atomic disable and update") added the old_state variable instead of what used to be a parameter, but it also removed the sole user of that variable in the vop_plane_atomic_update function leading to an usused variable. Remove it.

2021-02-25drm: Use state helper instead of the plane state pointerMaxime Ripard
Many drivers reference the plane->state pointer in order to get the current plane state in their atomic_update or atomic_disable hooks, which would be the new plane state in the global atomic state since _swap_state happened when those hooks are run. Use the drm_atomic_get_new_plane_state helper to get that state to make it more obvious.

2021-02-24drm: Rename plane->state variables in atomic update and disableMaxime Ripard
Some drivers are storing the plane->state pointer in atomic_update and atomic_disable in a variable simply called state, while the state passed as an argument is called old_state.

2021-02-23drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpersThomas Zimmermann
The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting, but currently located next to framebuffer helpers. Move it to GEM atomic helpers, rename it slightly and adopt the drivers. Same for the rsp simple-pipe helper. Compile-tested with x86-64, aarch64 and arm. The patch is fairly large, but there are no functional changes. v3: * remove out-comented line in drm_gem_framebuffer_helper.h (Maxime) v2: * rename to drm_gem_plane_helper_prepare_fb() (Daniel) * add tutorial-style documentation Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maxime Ripard <mripard@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210222141756.7864-1-tzimmermann@suse.de
2020-12-15drm: automatic legacy gamma supportTomi Valkeinen
To support legacy gamma ioctls the drivers need to set drm_crtc_funcs.gamma_set either to a custom implementation or to drm_atomic_helper_legacy_gamma_set. Most of the atomic drivers do the latter. We can simplify this by making the core handle it automatically. Move the drm_atomic_helper_legacy_gamma_set() functionality into drm_color_mgmt.c to make drm_mode_gamma_set_ioctl() use drm_crtc_funcs.gamma_set if set or GAMMA_LUT property if not.

2020-06-17drm/rockchip: Add per-pixel alpha support for the PX30 VOPPaul Kocialkowski
Compared to its predecessors, the PX30 VOP has a different register layout for enabling per-pixel alpha. Instead of src_alpha_ctl and dst_alpha_ctl, there is a single alpha control register. This register takes some fields from src_alpha_ctl, but with a different layout. Add support for the required fields to the PX30 VOP window descriptions, which makes per-pixel-alpha formats behave correctly.

2019-10-11drm/rockchip: Add optional support for CRTC gamma LUTEzequiel Garcia
Add an optional CRTC gamma LUT support, and enable it on RK3288. This is currently enabled via a separate address resource, which needs to be specified in the devicetree. The address resource is required because on some SoCs, such as RK3288, the LUT address is after the MMU address, and the latter is supported by a different driver. This prevents the DRM driver from requesting an entire register space. The current implementation works for RGB 10-bit tables, as that is what seems to work on RK3288.

2019-10-09drm/rockchip: Round up _before_ giving to the clock frameworkDouglas Anderson
I'm embarassed to say that even though I've touched vop_crtc_mode_fixup() twice and I swear I tested it, there's still a stupid glaring bug in it. Specifically, on veyron_minnie (with all the latest display timings) we want to be setting our pixel clock to 66,666,666.67 Hz and we tell userspace that's what we set, but we're actually choosing 66,000,000 Hz. This is confirmed by looking at the clock tree. The problem is that in drm_display_mode_from_videomode() we convert from Hz to kHz with: dmode->clock = vm->pixelclock / 1000; ...and drm_display_mode_from_videomode() is called from panel-simple when we have an "override_mode" like we do on veyron_minnie. See commit 123643e5c40a ("ARM: dts: rockchip: Specify rk3288-veyron-minnie's display timings"). ...so when the device tree specifies a clock of 66666667 for the panel then DRM translates that to 66666000. The clock framework will always pick a clock that is _lower_ than the one requested, so it will refuse to pick 66666667 and we'll end up at 66000000. While we could try to fix drm_display_mode_from_videomode() to round to the nearest kHz and it would fix our problem, it wouldn't help if the clock we actually needed was 60,000,001 Hz. We could alternatively have DRM always round up, but maybe this would break someone else who already baked in the assumption that DRM rounds down. Specifically note that clock drivers are not consistent about whether they round up or round down when you call clk_set_rate(). We know how Rockchip's clock driver works, but (for instance) you can see that on most Qualcomm clocks the default is clk_rcg2_ops which rounds up. Let's solve this by just adding 999 Hz before calling clk_round_rate(). This should be safe and work everywhere. As discussed in more detail in comments in the commit, Rockchip's PLLs are configured in a way that there shouldn't be another PLL setting that is only a few kHz off so we won't get mixed up. NOTE: if this is picked to stable, it's probably easiest to first pick commit 527e4ca3b6d1 ("drm/rockchip: Base adjustments of the mode based on prev adjustments") which shouldn't hurt in stable.

2019-09-19drm: Measure Self Refresh Entry/Exit times to avoid thrashingSean Paul
Currently the self refresh idle timer is a const set by the crtc. This is fine if the self refresh entry/exit times are well-known for all panels used on that crtc. However panels and workloads can vary quite a bit, and a timeout which works well for one doesn't work well for another. In the extreme, if the timeout is too short we could get in a situation where the self refresh exits are taking so long we queue up a self refresh entry before the exit commit is even finished. This patch changes the idle timeout to a moving average of the entry times + a moving average of exit times + the crtc constant. This patch was tested on rockchip, with a kevin CrOS panel the idle delay averages out to about ~235ms (35 entry + 100 exit + 100 const). On the same board, the bob panel idle delay lands around ~340ms (90 entry + 150 exit + 100 const). WRT the dedicated mutex in self_refresh_data, it would be nice if we could rely on drm_crtc.mutex to protect the average times, but there are a few reasons why a separate lock is a better choice: - We can't rely on drm_crtc.mutex being held if we're doing a nonblocking commit - We can't grab drm_crtc.mutex since drm_modeset_lock() doesn't tell us whether the lock was already held in the acquire context (it eats -EALREADY), so we can't tell if we should drop it or not - We don't need such a heavy-handed lock for what we're trying to do, commit ordering doesn't matter, so a point-of-use lock will be less contentious Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link to v1: https://patchwork.freedesktop.org/patch/msgid/20190917200443.64481-2-sean@poorly.run Link: https://patchwork.freedesktop.org/patch/msgid/20190918200734.149876-2-sean@poorly.run Changes in v2: - Migrate locking explanation from comment to commit msg (Daniel) - Turf constant entry delay and multiply the avg times by 2 (Daniel)

2019-06-16drm/rockchip: Base adjustments of the mode based on prev adjustmentsDouglas Anderson
In vop_crtc_mode_fixup() we fixup the mode to show what we actually will be able to achieve. However we should base our adjustments on any previous adjustments that were made. As an example, the dw_hdmi driver may wish to make some small adjustments to clock rates in its atomic_check() function. If it does, it will update the adjusted_mode. We shouldn't throw away those adjustments. NOTE: the version of the dw_hdmi driver upstream doesn't _actually_ make such adjustments, but downstream in Chrome OS it does. It is plausible that one day we'll figure out how to cleanly make that happen in an upstream-friendly way, so we should prepare by using the right mode.

2019-06-16drm/rockchip: Properly adjust to a true clock in adjusted_modeDouglas Anderson
When fixing up the clock in vop_crtc_mode_fixup() we're not doing it quite correctly. Specifically if we've got the true clock 266666667 Hz, we'll perform this calculation: 266666667 / 1000 => 266666 Later when we try to set the clock we'll do clk_set_rate(266666 * 1000). The common clock framework won't actually pick the proper clock in this case since it always wants clocks <= the specified one. Let's solve this by using DIV_ROUND_UP.

2019-06-04drm/rockchip: fix fb references in async updateHelen Koike
In the case of async update, modifications are done in place, i.e. in the current plane state, so the new_state is prepared and the new_state is cleaned up (instead of the old_state, unlike what happens in a normal sync update). To cleanup the old_fb properly, it needs to be placed in the new_state in the end of async_update, so cleanup call will unreference the old_fb correctly. Also, the previous code had a: plane_state = plane->funcs->atomic_duplicate_state(plane); ... swap(plane_state, plane->state); if (plane->state->fb && plane->state->fb != new_state->fb) { ... } Which was wrong, as the fb were just assigned to be equal, so this if statement nevers evaluates to true. Another details is that the function drm_crtc_vblank_get() can only be called when vop->is_enabled is true, otherwise it has no effect and trows a WARN_ON(). Calling drm_atomic_set_fb_for_plane() (which get a referent of the new fb and pus the old fb) is not required, as it is taken care by drm_mode_cursor_universal() when calling drm_atomic_helper_update_plane().

2019-05-20drm: Remove users of drm_format_(horz|vert)_chroma_subsamplingMaxime Ripard
drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling are basically a lookup in the drm_format_info table plus an access to the hsub and vsub fields of the appropriate entry. Most drivers are using this function while having access to the entry already, which means that we will perform an unnecessary lookup. Removing the call to these functions is therefore more efficient. Some drivers will not have access to that entry in the function, but in this case the overhead is minimal (we just have to call drm_format_info() to perform the lookup) and we can even avoid multiple, inefficient lookups in some places that need multiple fields from the drm_format_info structure. This is amplified by the fact that most of the time the callers will have to retrieve both the vsub and hsub fields, meaning that they would perform twice the lookup.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

Add the KMS plane rotation property to the DRM rockchip driver, for SoCs RK3328, RK3368 and RK3399. RK3288 only supports rotation at the display level (i.e. CRTC), but for now we are only interested in plane rotation. This commit only adds support for the value of reflect-y and reflect-x (i.e. mirroring). Note that y-mirroring is not compatible with YUV. The following modetest commands would test this feature, where 30 is the plane ID, and 49 = rotate_0 + relect_y + reflect_x.
