2017-08-03drm: rcar-du: Repair vblank for DRM page flips using the VSPKieran Bingham3-5/+13
The driver recently switched from handling page flip completion in the DU vertical blanking handler to the VSP frame end handler to fix a race condition. This unfortunately resulted in incorrect timestamps in the vertical blanking events sent to userspace as vertical blanking is now handled after sending the event. To fix this we must reverse the order of the two operations. The easiest way is to handle vertical blanking in the VSP frame end handler before sending the event. The VSP frame end interrupt occurs approximately 50µs earlier than the DU frame end interrupt, but this should not cause any undue harm. As we need to handle vertical blanking even when page flip completion is delayed, the VSP driver now needs to call the frame end completion callback unconditionally, with a new argument to report whether page flip has completed. With this new scheme the DU vertical blanking interrupt isn't needed anymore, so we can stop enabling it.

2017-08-03drm: rcar-du: Fix race condition when disabling planes at CRTC stopLaurent Pinchart2-6/+60
When stopping the CRTC the driver must disable all planes and wait for the change to take effect at the next vblank. Merely calling drm_crtc_wait_one_vblank() is not enough, as the function doesn't include any mechanism to handle the race with vblank interrupts. Replace the drm_crtc_wait_one_vblank() call with a manual mechanism that handles the vblank interrupt race.

2017-08-03drm: rcar-du: Wait for flip completion instead of vblank in commit tailLaurent Pinchart1-1/+1
Page flips can take more than one vertical blanking to complete if arming the page flips races with the vertical blanking interrupt. Waiting for one vblank to complete the atomic commit in the commit tail handler is thus incorrect, and can lead to framebuffers being released while still being scanned out. Fix this by waiting for flip completion instead, using the drm_atomic_helper_wait_for_flip_done() helper.

2017-08-03drm: rcar-du: Setup planes before enabling CRTC to avoid flickerLaurent Pinchart3-29/+43
Commit 52055bafa1ff ("drm: rcar-du: Move plane commit code from CRTC start to CRTC resume") changed the order of the plane commit and CRTC enable operations to accommodate the runtime PM requirements. However, this introduced corruption in the first displayed frame, as the CRTC is now enabled without any plane configured. On Gen2 hardware the first frame will be black and likely unnoticed, but on Gen3 hardware we end up starting the display before the VSP compositor, which is more noticeable. To fix this, revert the order of the commit operations back, and handle runtime PM requirements in the CRTC .atomic_begin() and .atomic_enable() helper operation handlers.

2017-08-03drm: rcar-du: Restrict DPLL duty cycle workaround to H3 ES1.xLaurent Pinchart1-10/+27
The H3 ES1.x exhibits dot clock duty cycle stability issues. We can work around them by configuring the DPLL to twice the desired frequency, coupled with a /2 post-divider. This isn't needed on other SoCs and breaks HDMI output on M3-W for a currently unknown reason, so restrict the workaround to H3 ES1.x. From an implementation point of view, move work around handling outside of the rcar_du_dpll_divider() function by requesting a x2 DPLL output frequency explicitly. The existing post-divider calculation mechanism will then take care of dividing the clock by two automatically. While at it, print a more useful debugging message to ease debugging clock rate issues.

2017-05-22drm: rcar-du: Arm the page flip event after queuing the page flipLaurent Pinchart1-11/+11
The page flip event is armed in the atomic begin handler, creating a race condition with the frame end interrupt that could send the event before the atomic operation actually completes. To avoid that, arm the event in the atomic flush handler after queuing the page flip. This change doesn't fully close the race window, as the frame end interrupt could be generated before the page flip is committed to hardware but only handled after the event is armed. However, the race window is now much smaller.

2017-02-02drm: Rely on mode_config data for fb_helper initializationGabriel Krisman Bertazi1-1/+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.

Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not needed in the header. <drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.
