2019-04-10drm: switch drm_fb_xrgb8888_to_rgb565_dstclip to accept __iomem dstGerd Hoffmann1-3/+3
Not all archs have the __io_virt() macro, so cirrus can't simply convert pointers that way. The drm format helpers have to use memcpy_toio() instead. This patch makes drm_fb_xrgb8888_to_rgb565_dstclip() accept a __iomem dst pointer and use memcpy_toio() instead of memcpy(). The helper function (drm_fb_xrgb8888_to_rgb565_line) has been changed to process a single scanline.

This patch makes drm_fb_memcpy_dstclip() accept a __iomem dst pointer and use memcpy_toio() instead of memcpy(). With that separating out the memcpy loop into the drm_fb_memcpy_lines() helper isn't useful any more, so move the code back into the calling functins.

2019-04-01drm/i915: Split some PCI ids into separate groupsTvrtko Ursulin1-49/+124
This will enable the following patch to consolidate most device ids into i915_pciids.h. While cross-referencing the ids listed in i915_drv.h, with the ones listed in i915_pciids.h, and also the comments in the latter, a bug for bug approach was used. This means two things: 1. Some ids are only present in i915_drv.h - obviously this means those parts would not have been probed at all so they were not added to i915_pciids.h 2. Some part type comments in i915_pciids.h were in disagreement with i915_drv.h. For instance parts labeled as ULT or ULX were not considered as such in i915_drv.h. The existing behaviour takes precedence here.

2019-03-18drm: writeback: Add job prepare and cleanup operationsLaurent Pinchart2-1/+34
As writeback jobs contain a framebuffer, drivers may need to prepare and cleanup them the same way they can prepare and cleanup framebuffers for planes. Add two new optional connector helper operations, .prepare_writeback_job() and .cleanup_writeback_job() to support this. The job prepare operation is called from drm_atomic_helper_prepare_planes() to avoid a new atomic commit helper that would need to be called by all drivers not using drm_atomic_helper_commit(). The job cleanup operation is called from the existing drm_writeback_cleanup_job() function, invoked both when destroying the job as part of a aborted commit, or when the job completes. The drm_writeback_job structure is extended with a priv field to let drivers store per-job data, such as mappings related to the writeback framebuffer. For internal plumbing reasons the drm_writeback_job structure needs to store a back-pointer to the drm_writeback_connector. To avoid pushing too much writeback-specific knowledge to drm_atomic_uapi.c, create a drm_writeback_set_fb() function, move the writeback job setup code there, and set the connector backpointer. The prepare_signaling() function doesn't need to allocate writeback jobs and can ignore connectors without a job, as it is called after the writeback jobs are allocated to store framebuffers, and a writeback fence with a framebuffer is an invalid configuration that gets rejected by the commit check.

2019-03-18drm: writeback: Cleanup job ownership handling when queuing jobLaurent Pinchart1-1/+1
The drm_writeback_queue_job() function takes ownership of the passed job and requires the caller to manually set the connector state writeback_job pointer to NULL. To simplify drivers and avoid errors (such as the missing NULL set in the vc4 driver), pass the connector state pointer to the function instead of the job pointer, and set the writeback_job pointer to NULL internally.

The DRM bus flags convey additional information on pixel data on the bus. All current available bus flags might be of interest for a bridge. Remove the sampling_edge field and use bus_flags. In the case at hand a dumb VGA bridge needs a specific data enable polarity (DRM_BUS_FLAG_DE_LOW).

The DRM_BUS_FLAG_PIXDATA_(POS|NEG)EDGE and DRM_BUS_FLAG_SYNC_(POS|NEG)EDGE flags are deprecated in favour of the new DRM_BUS_FLAG_PIXDATA_(DRIVE|SAMPLE)_(POS|NEG)EDGE and new DRM_BUS_FLAG_SYNC_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags. Replace them through the code. This effectively changes the value of the .sampling_edge bridge timings field in the dumb-vga-dac driver. This is safe to do as no driver consumes these values yet.

2019-03-18drm: Clarify definition of the DRM_BUS_FLAG_(PIXDATA|SYNC)_* macrosLaurent Pinchart1-4/+32
The DRM_BUS_FLAG_PIXDATA_POSEDGE and DRM_BUS_FLAG_PIXDATA_NEGEDGE macros and their DRM_BUS_FLAG_SYNC_* counterparts define on which pixel clock edge data and sync signals are driven. They are however used in some drivers to define on which pixel clock edge data and sync signals are sampled, which should usually (but not always) be the opposite edge of the driving edge. This creates confusion. Create four new macros for both PIXDATA and SYNC that explicitly state the driving and sampling edge in their name to remove the confusion. The driving macros are defined as the opposite of the sampling macros to made code simpler based on the assumption that the driving and sampling edges are opposite.
