[ Upstream commit 1ec06c2dee679e9f089e78ed20cb74ee90155f61 ]
On systems with multiple SH per SE compute_static_thread_mgmt_se#
is split into independent masks, one for each SH, in the upper and
lower 16 bits. We need to detect this and apply cu masking to each
SH. The cu mask bits are assigned first to each SE, then to
alternate SHs, then finally to higher CU id. This ensures that
the maximum number of SPIs are engaged as early as possible while
balancing CU assignment to each SH.
v2: Use max SH/SE rather than max SH in cu_per_sh.
v3: Fix comment blocks, ensure se_mask is initially zero filled,
and correctly assign se.sh.cu positions to unset bits in cu_mask.

Introduce a new mqd allocation interface and split the original
init_mqd function into two functions: allocate_mqd and init_mqd.
Also renamed uninit_mqd to free_mqd. This is preparation work to
fix a circular lock dependency.

Translate queue priority into pipe priority and write to MQDs.
The priority values are used to perform queue and pipe arbitration.

Wavefront context save data is of interest to userspace clients for
debugging static wavefront state. The MQD contains two parameters
required to parse the control stack and the control stack itself
is kept in the MQD from gfx9 onwards.
Add an ioctl to fetch the context save area and control stack offsets
and to copy the control stack to a userspace address if it is kept in
the MQD.

CU-masking allows a KFD client to control the set of CUs used by a
user mode queue for executing compute dispatches. This can be used
for optimizing the partitioning of the GPU and minimize conflicts
between concurrent tasks.

The mqd_manager module handles MQD data structures.
MQD stands for Memory Queue Descriptor, which is used by the H/W to
keep the usermode queue state in memory.
v3:
Removed new typedefs
Removed pragma pack 4
Remove cik_mqds.h file
Changed lower_32/upper_32 calls to use linux macros
Used new gart allocation functions
Added documentation
v4:
Added missing initialization of the addr field in init_mqd()
Setting the hqd persistent.preload_req bit ON so that when queues switches
on/off, their context will kept and read from the mqd when the cp reassign
them, and thus the dispatched workload context kept consistent without any
interrupts.
v5:
Move amdkfd from drm/radeon/ to drm/amd/
Change format of mqd structure to match latest KV firmware
Add support for AQL queues creation to enable working with open-source HSA
runtime.
