commit b2a7e9735ab2864330be9d00d7f38c961c28de5d upstream.

The system reboot failed as some IP blocks enter power gate before perform
hw resource destory. Meanwhile use unify interface to set device CGPG to ungate
state can simplify the amdgpu poweroff or reset ungate guard.

[ Upstream commit 487eca11a321ef33bcf4ca5adb3c0c4954db1b58 ]

The system will be hang up during S3 suspend because of SMU is pending
for GC not respose the register CP_HQD_ACTIVE access request.This issue
root cause of accessing the GC register under enter GFX CGGPG and can
be fixed by disable GFX CGPG before perform suspend.

v2: Use disable the GFX CGPG instead of RLC safe mode guard.

commit 2960758cce2310774de60bbbd8d6841d436c54d9 upstream.

Make the fw_write_wait default case true since presumably all new
gfx9 asics will have updated firmware. That is using unique WAIT_REG_MEM
packet with opration=1.

commit 5bbc6604a62814511c32f2e39bc9ffb2c1b92cbe upstream.

The offset into the array was specified in bytes but should
be in terms of 32-bit words.  Also prevent large reads that
would also cause a buffer overread.

v2:  Read from correct offset from internal storage buffer.

[ Upstream commit 2ab7e274b86739f4ceed5d94b6879f2d07b2802f ]

The TDR will be randomly failed due to compute ring
test failure. If the compute ring wptr &amp; 0x7ff(ring_buf_mask)
is 0x100 then after map mqd the compute ring rptr will be
synced with 0x100. And the ring test packet size is also 0x100.
Then after invocation of amdgpu_ring_commit, the cp will not
really handle the packet on the ring buffer because rptr is equal to wptr.
