The call to virtio_gpu_modeset_fini() in the unregister
code path needs this too.
Otherwise the patch looks good to me, so with that fixed:

I am not sure if Tiles is appropriate usage here. Since MTL does not have the
concept of tiles.
Shouldn't we be using gt instead of tile in our usage?

Using DEFINE_SIMPLE_ATTRIBUTE macro with the debugfs_create_file()
function adds the overhead of introducing a proxy file operation
functions to wrap the original read/write inside file removal protection
functions. This adds significant overhead in terms of introducing and
managing the proxy
A call to platform_get_irq() already prints an error on failure within
its own implementation. So printing another error based on its return
value in the caller is redundant and should be removed. The clean up
also makes if condition block braces unnecessary. Remove that as well.

Implement fbdev emulation that is optimized for drivers that use
DMA helpers. The buffers may no tbe moveable, may not require damage
handling and have to be located in system memory. This allows fbdev
emulation to operate directly on the buffer and mmap it to userspace.
Besides those
Add fbdev emulation that is optimized for DMA helpers, as used by most
drivers. It operates directly on GEM DMA buffers in system memory.
Memory pages are mmap'ed directly to userspace. No implicit shadow
buffers need to be allocated; as can happen with the generic fbdev
emulation. Convert drivers

dma_fence_wait_timeout (along with a host of other jiffies-based
timeouting functions) returns zero both in case of timeout and when
the wait completes during the last jiffy before timeout. As such,
we can't rely on it to distinguish between success and timeout.

There are two reasons why mutex is better here:
1. There's a critical section relatively long, where in
certain scenarios (e.g., multiple VM allocations) taking a spinlock
might cause noticeable performance degradation.
2. It will remove the incorrect usage of mutex under

The PDMA/EDMA is_idle routines didn't check the correct CORE register
in order to get the accurate idle state.
Moreover, it's better to make the is_idle routine more robust by adding
additional checks (IS_HALTED) before announcing that the core is idle.
