Having a fence linked to a virtio_gpu_framebuffer in the plane update sequence
would cause conflict when several planes referencing the same framebuffer

and those planes are updated concurrently. So it is needed to allocate
The patch "drm/virtio: new fence for every plane update" is to prevent a fence
synchronization problem when multiple planes are referencing a single large FB

One example of a possible problematic flow is

Hi all,
Today's linux-next merge of the drm-intel tree got a conflict in:
drivers/gpu/drm/i915/i915_drv.h
between commits:

The kernel produces a warning splat and the DSI device fails to register

Report the maximum number of IBs that can be pushed with a single
DRM_IOCTL_NOUVEAU_EXEC through DRM_IOCTL_NOUVEAU_GETPARAM.
While the maximum number of IBs per ring might vary between chipsets,
the kernel will make sure that userspace can only push a fraction of the
maximum number of IBs per ring
Use channel class definitions instead of magic numbers.

Same problem on powerpc CI tests, all boot target failed, most of them
with similar OOPS, see

Don't return early if one of the GT doesn't require
any flushing.

1) Keep the curly brace aligned.
2) No indentation by double tabs where single tab indentation is enough.

The mentioned second parameter is the 'u32 size', but it is not get used by
the etnaviv_gem_new_impl() function, so drop it. No functional change.

This patch make the code in the etnaviv_pdev_probe() less twisted, and it
also make it easier to drop the reference to device node after finished.
Before apply this patch, there is no call to of_node_put() when done. We
should call of_node_put() when done.

As in the etnaviv_gem_get_pages() function, the point to the drm_device
has already been cached to the 'dev' local variable. We can use it
directly, While at it, using 'unsigned int' type to count the number of
pages. As the drm_prime_pages_to_sg() function takes an unsigned int type

Sui Jingfeng (5):
drm/etnaviv: Drop the second argument of the etnaviv_gem_new_impl()
drm/etnaviv: Fix coding style
drm/etnaviv: Add helper functions to create and destroy platform

drm/etnaviv: Add a helper to get the first available GPU dev
The newly introduced functions are etnaviv_create_platform_device() and
etnaviv_destroy_platform_device(). Those two function are pure function
and can be shared for other use case. Currently, the benefit is that we
no longer need to call of_node_put() for three different cases, we only
need to cal

The MediaTek DRM driver implements GEM PRIME vmap by fetching the
sg_table for the object, iterating through the pages, and then
vmapping them. In essence, unlike the GEM DMA helpers which vmap
when the object is first created or imported, the MediaTek version
does it on request.
