drm/amdkfd: Introduce kfd_node struct (v5) Introduce a new structure, kfd_node, which will now represent a compute node. kfd_node is carved out of kfd_dev structure. kfd_dev struct now will become the parent of kfd_node, and will store common resources such as doorbells, GTT sub-alloctor etc. kfd_node struct will store all resources specific to a compute node, such as device queue manager, interrupt handling etc. This is the first step in adding compute partition support in KFD. v2: introduce kfd_node struct to gc v11 (Hawking) v3: make reference to kfd_dev struct through kfd_node (Morris) v4: use kfd_node instead for kfd isr/mqd functions (Morris) v5: rebase (Alex) Signed-off-by: Mukul Joshi <mukul.joshi@amd.com> Tested-by: Amber Lin <Amber.Lin@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Morris Zhang <Shiwu.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

drm/amdkfd: Support process XNACK mode dynamic change Update queue qpd is done for the first queue creation of the process, if the device support XNACK mode per process, update qpd setup sh_mem_config based on the process XNACK mode, to support the process destroy all queues, change XNACK mode, and then create queues. Add helper macro KFD_SUPPORT_XNACK_PER_PROCESS to remove duplicate code and add new ASICs support in future.

drm/amdkfd: add xnack enabled flag to kfd_process XNACK mode controls the SQ RETRY_DISABLE setting that determines, whether recoverable page faults can be supported on GFXv9 hardware. Only on Aldebaran we can support different processes running with different XNACK modes. On older chips all processes must use the same RETRY_DISABLE setting. However, processes not relying on recoverable page faults can work with RETRY enabled. This means XNACK off is always available as a fallback so we can use the same mode on all GPUs in a process.

drm/amdkfd: implement the dGPU fallback path for apu (v6) We still have a few iommu issues which need to address, so force raven as "dgpu" path for the moment. This is to add the fallback path to bypass IOMMU if IOMMU v2 is disabled or ACPI CRAT table not correct. v2: Use ignore_crat parameter to decide whether it will go with IOMMUv2. v3: Align with existed thunk, don't change the way of raven, only renoir will use "dgpu" path by default. v4: don't update global ignore_crat in the driver, and revise fallback function if CRAT is broken. v5: refine acpi crat good but no iommu support case, and rename the title. v6: fix the issue of dGPU initialized firstly, just modify the report value in the node_show().

drm/amdkfd: Consistently apply noretry setting Apply the same setting to SH_MEM_CONFIG and VM_CONTEXT1_CNTL. This makes the noretry param no longer KFD-specific. On GFX10 I'm not changing SH_MEM_CONFIG in this commit because GFX10 has different retry behaviour in the SQ and I don't have a way to test it at the moment.
