2020-03-18drm: convert .debugfs_init() hook to return void.Wambui Karuga2-3/+2
As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.

The plan is use have both shmem and virtual "vram" running side-by-side in virtio-gpu. It looks like we'll eventually use struct drm_gem_object as a base class, and we'll need to convert to shmem and vram objects on the fly. As a first step, add a virtio_gpu_is_shmem helper.

Drop the virtio_gpu_{disable,enable}_notify(). Add a new virtio_gpu_notify() call instead, which must be called whenever the driver wants make sure the host is notified needed. Drop automatic notification from command submission. Add virtio_gpu_notify() calls after each command query instead. This allows more fine-grained control over host notification and can move around the notify calls in subsequent patches to batch command submissions. With this in place it is also possible to make notification optional for userspace ioctls.

2020-02-12drm/virtio: add drm_driver.release callback.Gerd Hoffmann5-17/+27
Split virtio_gpu_deinit(), move the drm shutdown and release to virtio_gpu_release(). Drop vqs_ready variable, instead use drm_dev_{enter,exit,unplug} to avoid touching hardware after device removal. Tidy up here and there. v4: add changelog. v3: use drm_dev_*().

2020-02-10drm/virtio: move virtio_gpu_mem_entry initialization to new functionGerd Hoffmann3-50/+60
Introduce new virtio_gpu_object_shmem_init() helper function which will create the virtio_gpu_mem_entry array, containing the backing storage information for the host. For the most path this just moves code from virtio_gpu_object_attach().

2020-02-10drm/virtio: move mapping teardown to virtio_gpu_cleanup_object()Gerd Hoffmann3-50/+12
Stop sending DETACH_BACKING commands, that will happening anyway when releasing resources via UNREF. Handle guest-side cleanup in virtio_gpu_cleanup_object(), called when the host finished processing the UNREF command.

2020-02-07drm/virtio: fix ring free checkGerd Hoffmann4-0/+8
If the virtio device supports indirect ring descriptors we need only one ring entry for the whole command. Take that into account when checking whenever the virtqueue has enough free entries for our command.

2020-02-06drm/virtio: remove incorrect ENOSPC checkChia-I Wu1-13/+6
The handling of virtqueue_add_sgs ENOSPC error is incorrect because it can result in out-of-order virtqueue_add_sgs and break fences. We never get ENOSPC anyway because the caller waits until there is enough space (the other caller that did not wait was removed in commit 32d6c2c5b522 ("drm/virtio: Rewrite virtio_gpu_queue_ctrl_buffer using fenced version.")). Remove the incorrect and unnecessary error path. This also adds a WARN_ON(ret) until we properly handle errors.
