2016-03-03drm/omap: fix suspend/resume handlingTomi Valkeinen4-67/+44
For legacy reasons omapdss handles system suspend/resume via PM notifier callback, where the driver disables/resumes all the outputs. This doesn't work well with omapdrm. What happens on suspend is that the omapdss disables the displays while omapdrm is still happily continuing its work, possibly waiting for an vsync irq, which will never come if the display output is disabled, leading to timeouts and errors sent to userspace. This patch moves the suspend/resume handling to omapdrm, and the suspend/resume is now done safely inside modeset lock. Signed-off-by: Tomi Valkeinen <[email protected]>
2016-03-03drm/omap: check if rotation is supported before commitTomi Valkeinen3-0/+15
omapdrm is missing a check on the validity of the rotation property. This leads to omapdrm possibly trying to use rotation on non-rotateable framebuffer, which causes the overlay setup to fail. This patch adds the necessary check to omap_plane_atomic_check(). Signed-off-by: Tomi Valkeinen <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]>
2016-03-03drm/omap: fix crtc->plane property delegationTomi Valkeinen1-18/+40
Before universal planes we had to have plane specific properties for the crtc too, as on the hardware level a crtc uses a plane. In other words, e.g. 'zorder' property was added to both planes and crtcs, and omap_crtc.c would delegate the property set/get to the primary plane. However, the delegation was a bit too generic, delegating all property set/get calls to planes. Thus it's possible to set, say, FB_ID, on a crtc, which gets redirected to the primary plane. This is not standard, and shouldn't be allowed. To keep backward compatibility, we still need to redirect the properties we supported earlier for crtcs, namely 'zorder' and 'rotation'. This patch redirects only the allowed properties from crtcs to planes. Signed-off-by: Tomi Valkeinen <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]>

2016-03-03drm/omap: verify that fb plane pitches are the sameTomi Valkeinen1-0/+8
The DSS hardware uses the same ROW_INC value for both Y and UV planes for NV12 format. This means that the pitches of the Y and UV planes have to match. omapdrm doesn't check this at the moment, and this can lead into a broken NV12 fb on the screen. This patch adds the check.

On OMAP4 and OMAP5 ES1.0 the HDMI_WP_VIDEO_TIMING_H:HSW field is set directly to the HSW value. On later SoCs the field needs to be programmed with the value of HSW-1. Currently the driver always programs the field with the HSW value. Most videomodes seem to work fine with that, but at least low resolution interlaced modes don't work at all.

2016-03-03drm/omap: increase vblank wait timeoutTomi Valkeinen1-1/+5
omap_crtc_wait_pending() waits until the config changes have been taken into use, usually at next vblank. The wait-timeout used is 50ms, which usually is enough, but in some rare cases not. As time wait-timeout is just a safety measure for cases where something is broken, we can just as well increase the timeout considerably. This patch makes the timeout 250ms.

2016-03-03drm/omap: gem: Clean up GEM objects memory flagsLaurent Pinchart1-32/+25
The driver assumes that only objects backed by shmem need to be mapped through DMM. While this is true with the current code, the assumption won't hold with dma_buf import support. Condition the mapping based on whether the buffer has been allocated using the DMA mapping API instead and clean up the flags to avoid having to check both flags and GEM object filp field to decide how to process buffers. Flags are not the authoritative source of information regarding where the buffer memory comes from, and are renamed to make that clearer.

2016-03-03HACK: drm/omap: always use blocking DMM fillTomi Valkeinen1-0/+15
The current driver uses non-blocking DMM fill when releasing memory. This gives us a small performance increase as we don't have to wait for the fill operation to finish. However, the driver does not have any error handling for non-blocking fill. In case of an error, the fill operation may silently fail, leading to leaking DMM engines, which may eventually lead to deadlock if we run out of DMM engines. This patch makes the DMM driver always use blocking fills, so that we can catch the errors. A more complex option would be to allow non-blocking fills, and implement proper error handling, but that is left for the future. This patch is a HACK, as the proper fix is to either decide to always use sync fills and remove all the async related code, or fix the async code.

2016-03-03drm/omap: HDMI: change enable/disable to avoid sync-lostsTomi Valkeinen3-16/+21
We occasionally see DISPC sync-lost errors when enabling and disabling HDMI. Sometimes we get only a few, which get handled (ignored) by the driver, but sometimes there's a flood of the errors which doesn't seem to stop. The HW team has root caused this to the order in which HDMI and DISPC are enabled/disabled. Currently we enable HDMI first, and then DISPC, and vice versa when disabling. HW team's suggestion is to do it the other way around. This patch changes the order, but this has two side effects as the pixel clock is produced by HDMI, and the clock is not running when we enable/disable DISPC: * When enabling DISPC first, we don't get vertical sync events * When disabling DISPC last, we don't get FRAMEDONE event At the moment we use both of those to verify that DISPC has been enabled/disabled properly. Thus this patch also needs to change the omapdrm and omapdss which handle the DISPC side. Signed-off-by: Tomi Valkeinen <[email protected]> Acked-by: Laurent Pinchart <[email protected]>
