v2: individually allocate chain array, since chain node is free independently. v3: all existing points must be already signaled before cpu perform signal operation, so add check condition for that. v4: remove v3 change and add checking to prevent out-of-order v5: unify binary and timeline Signed-off-by:Chunming Zhou <david1.zhou@amd.com> Signed-off-by:

points array is one-to-one match with syncobjs array. v2: add seperate ioctl for timeline point wait, otherwise break uapi. v3: userspace can specify two kinds waits:: a.

Lockless container implementation similar to a dma_fence_array, but with only two elements per node and automatic garbage collection. v2: properly document dma_fence_chain_for_each, add dma_fence_chain_find_seqno, drop prev reference during garbage collection if it's not a chain fence. v3: use head and iterator for dma_fence_chain_for_each v4: fix reference count in dma_fence_chain_enable_signaling v5: fix iteration when walking each chain node v6: add __rcu for member 'prev' of struct chain node v7: fix rcu warnings from kernel robot Signed-off-by: -

The RK3066 HDMI TX serves as interface between a LCD Controller and a HDMI bus. A HDMI TX consists of one HDMI transmitter controller and one HDMI transmitter PHY. The interface has three (3) 8-bit data channels which can be configured for a number of bus widths (8/10/12/16/20/24-bit) and different video formats (RGB, YCbCr). Features: HDMI version 1.4a, HDCP revision 1.4 and DVI version 1.0 compliant transmitter. Supports DTV resolutions from 480i to 1080i/p HD. Master I2C interface for a DDC connection. HDMI TX supports multiple power save modes. The HDMI TX input can switch between LCDC0 and LCDC1. (Sound support is not included in this patch) Signed-off-by:

This patch moves the virtio_gpu_cmd_create_resource() call (which notifies the host about the new resource created) into the virtio_gpu_object_create() function. That way we can call virtio_gpu_cmd_create_resource() before ttm_bo_init(), so the host already knows about the object when ttm initializes the object and calls our driver callbacks. Specifically the object is already created when the virtio_gpu_ttm_tt_bind() callback invokes virtio_gpu_object_attach(), so the extra virtio_gpu_object_attach() calls done after virtio_gpu_object_create() are not needed any more. The fence support for the create ioctl becomes a bit more tricky though. The code moved into virtio_gpu_object_create() too. We first submit the (fenced) virtio_gpu_cmd_create_resource() command, then initialize the ttm object, and finally attach just created object to the fence for the command in case it didn't finish yet.

Add format, width and height fields to the virtio_gpu_object_params struct. With that in place we can use the parameter struct for virtio_gpu_cmd_create_resource() calls too. Signed-off-by:

Gerd Hoffmann authored
Create virtio_gpu_object_params, use that to pass object parameters to virtio_gpu_object_create. This is just the first step, followup patches will add more parameters to the struct. The plan is to use the struct for all object parameters. Drop unused "kernel" parameter for virtio_gpu_alloc_object(), it is unused and always false. Also drop "pinned" parameter. virtio-gpu doesn't shuffle around objects, so effecively they all are pinned anyway. Hardcode TTM_PL_FLAG_NO_EVICT so ttm knows. Doesn't change much for the moment as virtio-gpu supports TTM_PL_FLAG_TT only so there is no opportunity to move around objects. That'll probably change in the future though. Signed-off-by:

Gerd Hoffmann authored
Drop the dummy ttm backend implementation, add a real one for TTM_PL_FLAG_TT objects. The bin/unbind callbacks will call virtio_gpu_object_{attach,detach}, to update the object state on the host side, instead of invoking those calls from the move_notify() callback. With that in place the move and move_notify callbacks are not needed any more, so drop them. Signed-off-by: -

Looks like EDID_QUIRK_FIRST_DETAILED_PREFERRED never did anything. Its counterpart in f86EdidModes.c is properly hooked up but somehow that functionality was lost when it was copied into the kernel. The concensus seems to be that this quirk is a bit misguided anyway so let's nuke the leftovers.

Remove the unused DRM_DISPLAY_INFO_LEN from the uapi headers. I presume the original plan was to expose the display name via getconnector, but looks like that never happened. So we have the define for the length of the string but no string anywhere. A quick scan didn't seem to reveal userspace referencing this so hopefully we can just nuke it. Signed-off-by:

This changes the fb name from "nouveaufb" to "nouveaudrmfb". Aside: I wonder whether the in_interrupt() check is good enough for the nouveau acceleration. Cargo-cult says drm_can_sleep() is needed, which isn't actually working if you pick a .config without PREEMPT. For the generic fbdev defio support we've gone with offloading everything to a worker. For the non-accel callbacks (set_par, blank and friends) checking for oops_in_progress is good enough to catch all the evil calling contexts. v2: Rebase Acked-by:
