The feature allows the guest request an EDID blob (describing monitor capabilities) for a given scanout (aka virtual monitor connector). It brings a new command message, which has just a scanout field (beside the standard virtio-gpu header) and a response message which carries the EDID data. Signed-off-by:

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. Signed-off-by:

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:

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). Signed-off-by:

Fabrizio Castro authored
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.

The TPO TPG110 bindings were using the DPI bindings (popular in the fbdev subsystem) but this misses the finer points learned in the DRM subsystem. We need to augment the bindings for proper DRM integration: the timings are expressed by the hardware, not put into the device tree. I.e. this hardware is self-describing and can report the resolutions and timings needed. It should not be described in the device tree. Further the device was incorrectly modeled with GPIO lines instead of an SPI child, even though the device was using SPI. No known deployments of the device using device tree exist, so it should be fine to augment the bindings. Cc: devicetree@vger.kernel.org Reviewed-by:

When the execbuf call receives an in-fence it will get the dma_fence related to that fence fd and wait on it before submitting the draw call. On the out-fence side we get fence returned by the submitted draw call and attach it to a sync_file and send the sync_file fd to userspace. On error -1 is returned to userspace.

Add a new field called fence_fd that will be used by userspace to send in-fences to the kernel and receive out-fences created by the kernel. This uapi enables virtio to take advantage of explicit synchronization of dma-bufs. There are two new flags: * VIRTGPU_EXECBUF_FENCE_FD_IN to be used when passing an in-fence fd. * VIRTGPU_EXECBUF_FENCE_FD_OUT to be used when requesting an out-fence fd The execbuffer IOCTL is now read-write to allow the userspace to read the out-fence. On error -1 should be returned in the fence_fd field. Signed-off-by:

This patch adds support for the Primary Plane scaling. On the Amlogic GX SoCs, the primary plane is used as On-Screen-Display layer on top of video, and it's needed to keep the OSD layer to a lower size as the physical display size to : - lower the memory bandwidth - lower the OSD rendering - lower the memory usage This use-case is used when setting the display mode to 3840x2160 and the OSD layer is rendered using the GPU. In this case, the GXBB & GXL cannot work on more than 2000x2000 buffer, thus needing the OSD layer to be kept at 1920x1080 and upscaled to 3840x2160 in hardware. The primary plane atomic check still allow 1:1 scaling, allowing native 3840x2160 if needed by user-space applications. Signed-off-by:

The Amlogic Meson GX SoCs support an Overlay plane behind the primary plane for video rendering. This Overlay plane support various YUV layouts : - YUYV - NV12 / NV21 - YUV444 / 422 / 420 / 411 / 410 The scaler supports a wide range of scaling ratios, but for simplicity, plane atomic check limits the scaling from x5 to /5 in vertical and horizontal scaling. The z-order is fixed and always behind the primary plane and cannot be changed. The scaling parameter algorithm was taken from the Amlogic vendor kernel code and rewritten to match the atomic universal plane requirements. The video rendering using this overlay plane support has been tested using the new Kodi DRM-KMS Prime rendering path along the in-review V4L2 Mem2Mem Hardware Video Decoder up to 3840x2160 NV12 frames on various display modes.

Boris Brezillon authored
For the YUV conversion to work properly, ->x_scaling[1] should never be set to VC4_SCALING_NONE, but vc4_get_scaling_mode() might return VC4_SCALING_NONE if the horizontal scaling ratio exactly matches the horizontal subsampling factor. Add a test to turn VC4_SCALING_NONE into VC4_SCALING_PPF when that happens. The old ->x_scaling[0] adjustment is dropped as I couldn't find any mention to this constraint in the spec and it's proven to be unnecessary (I tested various multi-planar YUV formats with scaling disabled, and all of them worked fine without this adjustment).

Features such as dithering and pixel data edge configuration currently rely on the panel registered with the TCON driver. However, bridges are also supported in addition to panels for RGB setup. Instead of retrieving the connector from the panel, get it from the encoder with the dedicated helper. Even in the case of bridges, the connector is registered with the encoder from our driver and is accessible when iterating connectors. Signed-off-by:
