drm/virtio: move virtio_gpu_object_{attach, detach} calls.

2019-03-28T11:11:55+00:00

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.

drm/virtio: remove set but not used variable 'vgdev'

2019-03-28T11:11:47+00:00

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/virtio/virtgpu_ttm.c: In function 'virtio_gpu_init_mem_type':
drivers/gpu/drm/virtio/virtgpu_ttm.c:117:28: warning:

It is never used since introduction in dc5698e80cf7 ("Add virtio gpu driver.")

drm/ttm: Remove file_page_offset parameter from ttm_bo_device_init()

2019-03-19T20:03:53+00:00

The parameter file_page_offset is a constant shared by all drivers. Just
replace it with the constant itself.

drm/ttm: Define a single DRM_FILE_PAGE_OFFSET constant

2019-03-19T20:03:53+00:00

Most TTM drivers define the constant DRM_FILE_PAGE_OFFSET of the same
value. The only exception is vboxvideo, which is being converted to the
new offset by this patch. Unifying the constants in a single place
simplifies the driver code.

drm/ttm: initialize globals during device init (v2)

2018-11-05T19:21:21+00:00

Make sure that the global BO state is always correctly initialized.

This allows removing all the device code to initialize it.

v2: fix up vbox (Alex)

drm/ttm: use a static ttm_mem_global instance

2018-11-05T19:21:18+00:00

As the name says we only need one global instance of ttm_mem_global.

Drop all the driver initialization and just use a single exported
instance which is initialized during BO global initialization.

drm/ttm: Rename ttm_bo_global_{init,release}() to ttm_bo_global_ref_{,}()

2018-11-05T19:20:52+00:00

The functions ttm_bo_global_init() and ttm_bo_global_release() do not
receive an argument of type struct ttm_bo_global. Both take a struct
drm_global_reference that contains points to a struct ttm_bo_global_ref.
Renaming them reflects this.

drm/virtio: drop resource_id argument.

2018-10-29T21:50:55+00:00

We pass the obj anyway, so obj->hw_res_handle can be used instead
in virtio_gpu_object_attach() and virtio_gpu_cmd_create_resource().
