In amdvgpu_bo_free(), when the reference count drops to 0, vdrm_flush()
is called before removing the bo from the handle_to_vbo hash table.
Since vdrm_flush() is a time-consuming operation and is executed outside
of the handle_to_vbo_mutex lock, another thread calling amdvgpu_bo_import()
can concurrently find this bo in the hash table, increment its refcount,
and attempt to use it. Once vdrm_flush() finishes, amdvgpu_bo_free()
proceeds to remove the bo and call free(), leaving the importing thread
with a dangling pointer, which leads to a use-after-free or double free
crash.
To fix this race condition, we must remove the bo from the hash table
under the lock first. After the bo is safely unlinked and the lock is
released, we can then perform the time-consuming vdrm_flush() and the
actual memory release.

Currently the code handling deferred RTA clears cannot handle them for
secondary command buffers within render passes, because the code
immediately configures the transfer command for the deferred clear
operation, but the specific attachment image view isn't known when
recording secondary command buffers to be executed inside render passes.
Add code to record parameters for deferred RTA clears in secondary
command buffers when the attachment is unknown, and bind the recorded
clears to the attachment's image view when executing the secondary
command buffer inside a render pass.
Fixes many dynamic rendering random tests.

The code that adds deferred RTA clear transfer commands checks whether
the newly allocated transfer command is NULL. However the list_addtail
call is before the check, which means that the check does not prevent
NULL dereference.
Reorder the code to ensure no NULL transfer commands would ever be added
to the deferred clear list.
In addition, pvr_transfer_cmd_alloc() has already set the command
buffer's error status when it returns NULL, so it's not needed to set it
again.

For 2D array views of 3D images, the layer of the view corresponds to

Deferred RTA clear will happen after the current graphics subcommand is
executed, which may override rendered image in the graphics subcommand.
In addition, the active render targets do not need "emulated" clear --
they can be really cleared by drawing rectangles.
Skip set up deferred RTA clear for active render target layers, and
continue to do immediate clear for these layers.
Fixes a few dynamic rendering random CTS tests, but the issue should
also exist in legacy renderpasses RTA clears.

of maxPerStageDescriptorUniformBuffers,
maxPerStageDescriptorStorageBuffers, maxPerStageDescriptorSampledImages,

As maxPerStageDescriptorStorageBuffers is previously increased, the
