drm/amdkfd: Add initial VI support for KQ

2014-12-02T14:38:57Z

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 Signed-off-by: Ben Goz Signed-off-by: Oded Gabbay Reviewed-by: Alex Deucher
