A second-level user mode trap handler can be installed. The CWSR trap
handler jumps to the secondary trap handler conditionally for any
conditions not handled by it. This can be used e.g. for debugging or
catching math exceptions.

When CWSR is disabled, the user mode trap handler is installed as
first level trap handler.

This hardware feature allows the GPU to preempt shader execution in
the middle of a compute wave, save the state and restore it later
to resume execution.

Memory for saving the state is allocated per queue in user mode and
the address and size passed to the create_queue ioctl. The size
depends on the number of waves that can be in flight simultaneously
on a given ASIC.

The trap handler is like an interrupt handler running on the GPU
compute unit. It is needed for supporting CWSR (compute wave
save/restore).

This file defines an array with the pre-compiled GFXv8 shader ISA.
The assembly code is included for reference in #if 0 ... #endif.

Add wptr and mm parameters to hqd_sdma_load and pass these parameters
from device_queue_manager through the mqd_manager.

SDMA doesn't support polling while the engine believes it's idle. The
driver must update the wptr. The new parameters will be used for looking
up the updated value from the specified mm when SDMA queues are resumed
after being disabled.

validate_fbc never fails a modeset. It's simply used to decide whether
to use FBC or not. Calling it validate_fbc might be confusing to some so
rename it to should_enable_fbc.

With that let's also remove the DC_STATUS return code and return bool
and make enable_fbc a void function since we never check it's return
value and probably never want to anyways.
