2019-05-24drm/amdkfd: Introduce asic-specific mqd_manager_init functionOak Zeng1-0/+2
Global function mqd_manager_init just calls asic-specific functions and it is not necessary. Delete it and introduce a mqd_manager_init interface in dqm for asic-specific mqd manager init.

2018-01-04drm/amdkfd: Add dGPU support to the device queue managerFelix Kuehling1-0/+56
GFXv7 and v8 dGPUs use a different addressing mode for KFD compared to APUs (GPUVM64 vs HSA64). And dGPUs don't support MTYPE_CC. They use MTYPE_UC instead for memory that requires coherency.

2017-11-01drm/amdkfd: Cleanup DQM ASIC-specific opsYong Zhao1-13/+7
Remove empty initialize function. Rename register_process to update_qpd to avoid confusion with the non-ASIC-specific register_process. Shorten ops_asic_specific to asic_ops.

2017-08-15drm/amdkfd: Handle remaining BUG_ONs more gracefully v2Felix Kuehling1-1/+1
In most cases, BUG_ONs can be replaced with WARN_ON with an error return. In some void functions just turn them into a WARN_ON and possibly an early exit. v2: * Cleaned up error handling in pm_send_unmap_queue * Removed redundant WARN_ON in kfd_process_destroy_delayed Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2017-08-15drm/amdkfd: Remove BUG_ONs for NULL pointer argumentsFelix Kuehling1-2/+0
Remove BUG_ONs that check for NULL pointer arguments that are dereferenced in the same function. Dereferencing the NULL pointer will generate a BUG anyway, so the explicit check is redundant and unnecessary overhead.

2017-08-15drm/amdkfd: Consolidate and clean up log commandsKent Russell1-1/+1
Consolidate log commands so that dev_info(NULL, "Error...") uses the more accurate pr_err, remove the module name from the log (can be seen via dynamic debugging with +m), and the function name (can be seen via dynamic debugging with +f). We also don't need debug messages saying what function we're in. Those can be added by devs when needed Don't print vendor and device ID in error messages. They are typically the same for all GPUs in a multi-GPU system. So this doesn't add any value to the message. Lastly, remove parentheses around %d, %i and 0x%llX. According to kernel.org: "Printing numbers in parentheses (%d) adds no value and should be avoided."

2015-07-30drm/amdkfd: fix bug when initializing sdma vmOded Gabbay1-1/+1

2015-05-19drm/amdkfd: Use new struct for asic specific opsOded Gabbay1-1/+1
This patch creates a new structure for asic specific operations, instead of using the existing structure of operations. This is done to make the code flow more logic, readable and maintainable.

2015-02-23drm/amdkfd: Initialize only amdkfd's assigned pipelinesOded Gabbay1-1/+1
This patch fixes a bug in the initialization of the pipelines. The init_pipelines() function was called with a constant value of 0 in the first_pipe argument. This is an error because amdkfd doesn't handle pipe 0. The correct way is to pass the value that get_first_pipe() returns as the argument for first_pipe. This bug appeared in 3.19 (first version with amdkfd) and it causes around 15% drop in CPU performance of Kaveri (A10-7850). v2: Don't set get_first_pipe() as inline because it calls BUG_ON() Signed-off-by: Oded Gabbay <oded.gabbay@amd.com> Cc: stable@vger.kernel.org Tested-by: Michel Dänzer <michel.daenzer@amd.com>
2015-01-12drm/amdkfd: Add initial VI support for DQMBen Goz1-0/+135
This patch starts to add support for the VI APU in the DQM module. Because most (more than 90%) of the DQM code is shared among AMD's APUs, we chose a design that performs most/all the code in the shared DQM file (kfd_device_queue_manager.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 <ben.goz@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com>
