Jacob He 460c484f24 drm/amdgpu: Initialize SPM_VMID with 0xf (v2) 
SPM_VMID is a global resource, SPM access the video memory according to
SPM_VMID. The initial valude of SPM_VMID is 0 which is used by kernel.
That means UMD can overwrite the memory of VMID0 by enabling SPM, that
is really dangerous.

Initialize SPM_VMID with 0xf, it messes up other user mode process at
most.

v2: squash in indentation fix

* CP.
* On CIK, gfx and compute now have independant command processors.

* GFX
* Gfx consists of a single ring and can process both gfx jobs and
* compute jobs. The gfx CP consists of three microengines (ME):
* PFP - Pre-Fetch Parser
* ME - Micro Engine
* CE - Constant Engine
* The PFP and ME make up what is considered the Drawing Engine (DE).
* The CE is an asynchronous engine used for updating buffer desciptors
* used by the DE so that they can be loaded into cache in parallel
* while the DE is processing state update packets.
*
* Compute
* The compute CP consists of two microengines (ME):
* MEC1 - Compute MicroEngine 1
* MEC2 - Compute MicroEngine 2
* Each MEC supports 4 compute pipes and each pipe supports 8 queues.
* The queues are exposed to userspace and are programmed directly
* by the compute runtime.
