into drm-next drm/imx: error path fixes and cleanups - Fix use after free issue in component bind error path by keeping memory allocated as long as the driver is bound. This will be replaced with drm managed memory in the next round. - Fix bus_flags overriding logic in parallel-display. - Disable regulator in imx-tve bind error path. - Drop unnecessary best_encoder callback. - Remove an unused enum in imx-ldb. - Bail out early on missing panel or bridge in parallel-display to speed up -EPROBE_DEFER path. - Disable both LDB channels in split mode. - Restore RGB32, BGR32 format support. - Fix tiled image conversion in case of out of order interrupts. - Remove a superfluous error message in imx-tve.

2020-07-20drm/imx: fix use after freePhilipp Zabel1-1/+2
Component driver structures allocated with devm_kmalloc() in bind() are freed automatically after unbind(). Since the contained drm structures are accessed afterwards in drm_mode_config_cleanup(), move the allocation into probe() to extend the driver structure's lifetime to the lifetime of the device. This should eventually be changed to use drm resource managed allocations with lifetime of the drm device. We also need to ensure that all componets are available during the unbind() so we need to call component_unbind_all() before we free non-devres resources like planes. Note this patch fixes the the use after free bug but introduces a possible boot loop issue. The issue is triggered if the HDMI support is enabled and a component driver always return -EPROBE_DEFER, see discussion [1] for more details.

Add a zpos property to planes. Call drm_atomic_helper_check() instead of calling drm_atomic_helper_check_modeset() and drm_atomic_check_planes() manually. This effectively adds a call to drm_atomic_normalize_zpos() before checking planes. Reorder atomic update to allow changing plane zpos without modeset. Note that the initial zpos is set in ipu_plane_state_reset(). The initial value set in ipu_plane_init() is just for show. The zpos parameter of drm_plane_create_zpos_property() is ignored because the newly created plane do not have state yet.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-3/+3
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.

2018-09-25drm/imx: Use drm_fbdev_generic_setup()Noralf Trønnes1-15/+4
The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. CONFIG_DRM_FBDEV_EMULATION wasn't honoured by the CMA helper, but it is by drm_fb_helper.

2017-03-16drm/imx: use PRG/PRE when possibleLucas Stach1-0/+5
Allow the planes to use the PRG/PRE units as linear prefetchers when possible. This improves DRAM efficiency a bit and reduces the chance for display underflow when the memory subsystem is under load. This does not yet support scanning out tiled buffers directly, as this needs more work, but it already wires up the basic interaction between imx-drm, the IPUv3 driver and the PRG and PRE drivers.

2017-03-15drm/imx: add deferred plane disablingPhilipp Zabel1-0/+18
The DP (display processor) channel disable code tried to busy wait for the DP sync flow end interrupt status bit when disabling the partial plane without a full modeset. That never worked reliably, and it was disabled completely by the recent "gpu: ipu-v3: remove IRQ dance on DC channel disable" patch, causing ipu_wait_interrupt to always time out after 50 ms, which in turn would trigger a timeout in drm_atomic_helper_wait_for_vblanks. This patch changes ipu_plane_atomic_disable to only queue a DP channel register update at the next frame boundary and set a flag, which can be done without any waiting whatsoever. The imx_drm_atomic_commit_tail then calls a new ipu_plane_disable_deferred function that does the actual IDMAC teardown of the planes that are flagged for deferred disabling, after waiting for the vblank.

Less code ftw. This converts all drivers except the tinydrm helper module. That one needs more work, since it gets the THIS_MODULE reference from tinydrm.ko instead of the actual driver module like it should. Probably needs a similar trick like I used here with generating the entire struct with a macro.

With the vblank hooks in struct drm_crtc_funcs, we do not need to maintain the CRTC specific vblank callbacks with struct imx_drm_crtc_helper_funcs any more. By moving the stuff that we currently do in imx_drm_add_crtc(), like of_node setting and drm_crtc_helper_add()/drm_crtc_init_with_planes() invoking, we can kill things like struct imx_drm_crtc, imx_drm_crtc_helper_funcs and related functions completely. Functions ipu_enable_vblank() and ipu_disable_vblank() are moved around without changes, only for saving the forward declarations.

2017-02-02drm: Rely on mode_config data for fb_helper initializationGabriel Krisman Bertazi1-2/+1
Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // <smpl> @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // </smpl> Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.
