2019-03-28drm/virtio: rework resource creation workflow.Gerd Hoffmann6-91/+83
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.

2019-03-28drm/virtio: use struct to pass params to virtio_gpu_object_create()Gerd Hoffmann4-34/+35
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.

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.

2019-03-28drm: rcar-du: lvds: Fix post-DLL divider calculationLaurent Pinchart1-1/+1
The PLL parameters are computed by looping over the range of acceptable M, N and E values, and selecting the combination that produces the output frequency closest to the target. The internal frequency constraints are taken into account by restricting the tested values for the PLL parameters, reducing the search space. The target frequency, however, is only taken into account when computing the post-PLL divider, which can result in a 0 value for the divider when the PLL output frequency being tested is lower than half of the target frequency. Subsequent loops will produce a better set of PLL parameters, but for some of the iterations this can result in a division by 0. Fix it by clamping the divider value. We could instead restrict the E values being tested in the inner loop, but that would require additional calculation that would likely be less efficient as the E parameter can only take three different values.

This is valid for the LVDS and HDMI outputs, but the DPAD outputs can be connected directly to a panel, in which case no bridge is available.
