2018-11-27drm/meson: Add support for VIC alternate timingsNeil Armstrong3-52/+89
This change is an attempt to handle the alternate clock for the CEA mode. 60Hz vs. 59.94Hz, 30Hz vs 29.97Hz or 24Hz vs 23.97Hz on the Amlogic Meson SoC DRM Driver pixel clock generation. The actual clock generation will be moved to the Common Clock framework once all the video clock are handled by the Amlogic Meson SoC clock driver, then these alternate timings will be handled in the same time in a cleaner fashion.

Our hardware requires the pitch to be an even number when using YUV formats with the frontend. Implement a driver-specific callback for GEM dumb allocation that sets the pitch accordingly.

2018-11-27drm/sun4i: frontend: Apply format sub-sampling to CH1 dimensionsPaul Kocialkowski1-8/+16
The frontend comes with two "channels", that can be configured independently. When used in YUV mode, the first channel (CH0) represents the luminance component while the second channel (CH1) represents the chrominance. In RGB mode, both have to be configured the same way. Use variables (with the YUV terminology) for each channel's dimensions, calculating the chroma dimensions from the luma dimensions and the sub-sampling factors from the format description. Since the configured size only has pixel precision, the fractional fixed-point part of the source size is dropped for both components to ensure that the scaling factors are accurate.

Before this patch, it is assumed that a plane is supported either through the frontend or through the backend alone. However, the DRM interface does not allow finely reporting our hardware capabilities and there are cases where neither are support. In particular, some plane formats are supported by the backend and not the frontend, so they can only be supported without scaling.

2018-11-27drm/sun4i: frontend: Replace ARGB with XRGB as supported formatPaul Kocialkowski2-4/+3
The frontend documentation (for the A33) mentions that ARGB is supported as output, but with the alpha component always set to 0xff. In practice, this means that the alpha component cannot be preserved when going through the frontend. Since the information is lost, ARGB is not properly supported. As a result, expose the matching format supported by the frontend (both for input and output) as XRGB instead of ARGB. Since ARGB was the selected format for connecting the frontend to the backend, change it to XRGB to reflect this as well. The A31 and A80 SoCs apparently have a bit to enable proper alpha, but this is not supported at this point (see the comment already in the code).

2018-11-23drm/atomic-helper: Complete fake_commit->flip_done potentially earlierVille Syrjälä1-0/+3
Consider the following scenario: 1. nonblocking enable crtc 2. wait for the event 3. nonblocking disable crtc On i915 this can lead to a spurious -EBUSY from step 3 on account of non-enabled planes getting the fake_commit in step 1 and we don't complete the fake_commit-> flip_done until drm_atomic_helper_commit_hw_done() which can happen a long time after the flip event was sent out. This will become somewhat easy to hit on SKL+ once we start to add all the planes for the crtc to every modeset commit for the purposes of forcing a watermark register programming [1]. To make the race a little less pronounced let's complete fake_commit->flip_done after drm_atomic_helper_wait_for_flip_done(). For the single crtc case this should make the race quite theoretical, assuming drm_atomic_helper_wait_for_flip_done() actually has to wait for the real commit flip_done. In case the real commit flip_done gets completed singificantly before drm_atomic_helper_wait_for_flip_done(), or we are dealing with multiple crtcs whose vblanks don't line up nicely the race still exists.

2018-11-21qxl: Make sure qxl_cursor memory is pinnedChristophe Fergeau1-1/+9
QEMU keeps a vram reference to the last QXLCursorCmd it received. This QXLCursorCmd command points to a QXLCursor instance (stored in vram too). However, while the QXLCursorCmd memory is pinned, the QXLCursor memory is not. When booting a recent Fedora to its login screen while monitoring the QXLCursorCmd QEMU holds, it's possible to see the QXLCursor memory becoming invalid shortly after boot. Pinning that memory ensures that that QXLCursor memory is not going to be moved by the guest kernel. Moving the pin/unpin to qxl_release_list_add()/qxl_release_free_list() would be a more generic fix. However, doing this quickly exhausts QXL video memory, so more fixing would be needed before this is workable.

v5: This is YUV444 packed format same as AYUV, but without alpha, as supported by i915. v6: Removed unneeded initializer for new XYUV format. v7: Added is_yuv field initialization according to latest drm_fourcc format structure initialization changes. v8: Edited commit message to be more clear about skl+, renamed PLANE_CTL_FORMAT_AYUV to PLANE_CTL_FORMAT_XYUV as this format doesn't support per-pixel alpha. Fixed minor code issues. v9: Moved DRM format check to proper place in intel_framebuffer_init. v10: Changed DRM_FORMAT_XYUV to be DRM_FORMAT_XYUV8888 v11: Fixed rebase conflict, caused by added new formats to drm-tip meanwhile.

This adds functionality to the CMA helper which ensures that the kernel virtual address is set on the CMA GEM object also for imported buffers.

2018-11-20drm/gem: Add drm_gem_object_funcsNoralf Trønnes3-34/+121
This adds an optional function table on GEM objects. The main benefit is for drivers that support more than one type of memory (shmem,vram,cma) for their buffers depending on the hardware it runs on. With the callbacks attached to the GEM object itself, it is easier to have core helpers for the the various buffer types. The driver only has to make the decision about buffer type on GEM object creation and all other callbacks can be handled by the chosen helper. drm_driver->gem_prime_res_obj has not been added since there's a todo to put a reservation_object into drm_gem_object. v3: Add todo entry v2: Drop drm_gem_object_funcs->prime_mmap in favour of drm_gem_prime_mmap() (Daniel Vetter) v1: - drm_gem_object_funcs.map -> .prime_map let it only do PRIME mmap like the function it superseeds (Daniel Vetter) - Flip around the if ladders and make obj->funcs the first choice highlighting the fact that this the new default way of doing it (Daniel Vetter) Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181110145647.17580-4-noralf@tronnes.org

2018-11-20drm/bridge/sii902x: Add missing dependency on I2C_MUXFabrizio Castro1-0/+1
kbuild test robot reports: >> ERROR: "i2c_mux_add_adapter" [drivers/gpu/drm/bridge/sii902x.ko] undefined! >> ERROR: "i2c_mux_alloc" [drivers/gpu/drm/bridge/sii902x.ko] undefined! >> ERROR: "i2c_mux_del_adapters" [drivers/gpu/drm/bridge/sii902x.ko] undefined! Quite obviously the driver depends on I2C_MUX, but adding a "depends on" introduces a recursive dependency, therefore this patch selects I2C_MUX instead.

2018-11-19drm/rockchip: fix for mailbox read sizeDamian Kos1-1/+1
Some of the functions (like cdn_dp_dpcd_read, cdn_dp_get_edid_block) allow to read 64KiB, but the cdn_dp_mailbox_read_receive, that is used by them, can read only up to 255 bytes at once. Normally, it's not a big issue as DPCD or EDID reads won't (hopefully) exceed that value. The real issue here is the revocation list read during the HDCP authentication process. (problematic use case: https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/gpu/drm/rockchip/cdn-dp-reg.c#1152) The list can reach 127*5+4 bytes (num devs * 5 bytes per ID/Bksv + 4 bytes of an additional info). In other words - CTSes with HDCP Repeater won't pass without this fix. Oh, and the driver will most likely stop working (best case scenario).

2018-11-15drm/bridge/sii902x: Fix EDID readbackFabrizio Castro1-69/+178
While adding SiI9022A support to the iwg23s board, it came up that when the HDMI transmitter is in pass through mode the device is not compliant with the I2C specification anymore, as it requires a far bigger tbuf, due to a delay the HDMI transmitter is adding when relaying the STOP condition on the monitor i2c side of things. When not providing an appropriate delay after the STOP condition the i2c bus would get stuck. Also, any other traffic on the bus while talking to the monitor may cause the transaction to fail or even cause issues with the i2c bus as well. I2c-gates seemed to reach consent as a possible way to address these issues, and as such this patch is implementing a solution based on that. Since others are clearly relying on the current implementation of the driver, this patch won't require any DT changes. Since we don't want any interference during the DDC Bus Request/Grant procedure and while talking to the monitor, we have to use the adapter locking primitives rather than the i2c-mux locking primitives.
