685967b3c1 drm/amdgpu: Put MODE register in wave debug info
Add the MODE register into the per-wave debug information.
This register holds state such as FP rounding and denorm
modes, which exceptions are enabled, and active clamping
modes.

a5504e9ad4 drm/amdgpu: Indirect register access for Navi12 sriov
This patch series are used for GC/MMHUB(part)/IH_RB_CNTL
indirect access in the SRIOV environment.

There are 4 bits, controlled by host, to control
if GC/MMHUB(part)/IH_RB_CNTL indirect access enabled.
(one bit is master bit controls other 3 bits)

For GC registers, changing all the register access from MMIO to
RLC and use RLC as the default access method in the full access time.

For partial MMHUB registers, changing their access from MMIO to
RLC in the full access time, the remaining registers
keep the original access method.

For IH_RB_CNTL register, changing it's access from MMIO to PSP.

a3bab32585 drm/amdgpu: move amdgpu_num_kcq handling to a helper
Add a helper so we can set per asic default values. Also,
the module parameter is currently clamped to 8, but clamp it
per asic just in case some asics have different limits in the
future. Enable the option on gfx6,7 as well for consistency.

825c91d090 drm/amd/amdgpu: Prepare implementation to support reporting of CU usage
[Why]
Allow user to know number of compute units (CU) that are in use at any
given moment.

[How]
Read registers of SQ that give number of waves that are in flight
of various queues. Use this information to determine number of CU's
in use.
