2023-06-09drm/amdkfd: Update context save handling for multi XCC setup (v2)Mukul Joshi1-0/+1
Context save handling needs to be updated for a multi XCC setup: - On a multi XCC setup, KFD needs to report context save base address and size for each XCC in MQD. - Thunk will allocate a large context save area covering all XCCs which will be equal to: num_of_xccs in a partition * size of context save area for 1 XCC. However, it will report only the size of context save area for 1 XCC only in the ioctl call. - Driver then setups the MQD correctly using the size passed from Thunk and information about number of XCCs in a partition. - Update get_wave_state function to return context save area for all XCCs in the partition. v2: update the get_wave_state function for mqd manager v11 (Morris) 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: Morris Zhang <Shiwu.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2023-06-09drm/amdkfd: Introduce kfd_node struct (v5)Mukul Joshi1-4/+4
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>

2021-10-28drm/amdkfd: Add an optional argument into update queue operation(v2)Lang Yu1-1/+2
Currently, queue is updated with data in queue_properties. And all allocated resource in queue_properties will not be freed until the queue is destroyed. But some properties(e.g., cu mask) bring some memory management headaches(e.g., memory leak) and make code complex. Actually they have been copied to mqd and don't have to persist in queue_properties. Add an argument into update queue to pass such properties, then we can remove them from queue_properties. v2: Don't use void *.

2021-08-26drm/amdkfd: Account for SH/SE count when setting up cu masks.Sean Keely1-0/+1
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.

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.
