Oak Zeng 16631afff2 drm/amdkfd: Delete alloc_format field from map_queue struct
Alloc format was never really supported by MEC FW. FW always
does one per pipe allocation.

Oak Zeng 1b4670f698 drm/amdkfd: Introduce XGMI SDMA queue type
Existing QUEUE_TYPE_SDMA means PCIe optimized SDMA queues.
Introduce a new QUEUE_TYPE_SDMA_XGMI, which is optimized
for non-PCIe transfer such as XGMI.

Felix Kuehling f6e27ff19d drm/amdkfd: Move packet writer functions into ASIC-specific file
This is in preparation for GFXv9 (Vega10) which uses incompatible PM4
packet formats from previous ASIC generations.

Ben Goz 6898f0a568 drm/amdkfd: Add initial VI support for KQ
This patch starts to add support for the VI APU in the KQ (kernel queue)
module.

Because most (more than 90%) of the KQ code is shared among AMD's APUs, we
chose a design that performs most/all the code in the shared KQ file
(kfd_kernel_queue.c). If there is H/W specific code to be executed,
than it is written in an asic-specific extension function for that H/W.

That asic-specific extension function is called from the shared function at the
appropriate time. This requires that for every asic-specific extension function
that is implemented in a specific ASIC, there will be an equivalent
implementation in ALL ASICs, even if those implementations are just stubs.

That way we achieve:

- Maintainability: by having one copy of most of the code, we only need to
  fix bugs at one locations

- Readability: very clear what is the shared code and what is done per ASIC

- Extensibility: very easy to add new H/W specific files/functions
