289e6850 - drm/amdkfd: Set per-process flags only once cik/vi

Tue, 14 Jan 2025 19:07:24 +0000

drm/amdkfd: Set per-process flags only once cik/viSet per-process static sh_mem config only once during processinitialization. Move all static changes from update_qpd() which iscalled each time a queue is created to set_cache_memory_policy() whichis called once during process initialization.set_cache_memory_policy() is currently defined only for cik and vifamily. So this commit only focuses on these two.

drm/amdkfd: Consolidate and clean up log commandsConsolidate log commands so that dev_info(NULL, "Error...") uses the moreaccurate pr_err, remove the module name from the log (can be seen viadynamic debugging with +m), and the function name (can be seen viadynamic debugging with +f). We also don't need debug messages sayingwhat function we're in. Those can be added by devs when neededDon't print vendor and device ID in error messages. They are typicallythe same for all GPUs in a multi-GPU system. So this doesn't add anyvalue 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 beavoided."Signed-off-by: Kent Russell Signed-off-by: Yong Zhao Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay List of files: /linux-6.15/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager_cik.c

Theinit_pipelines() function was called with a constant value of 0 in thefirst_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 theargument 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 Cc: stable@vger.kernel.orgTested-by: Michel Dänzer List of files: /linux-6.15/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager_cik.c

a22fc854 - drm/amdkfd: Add initial VI support for DQM

Mon, 12 Jan 2015 12:28:46 +0000

drm/amdkfd: Add initial VI support for DQMThis 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, wechose 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 theappropriate time. This requires that for every asic-specific extension functionthat is implemented in a specific ASIC, there will be an equivalentimplementation 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/functionsSigned-off-by: Ben Goz Signed-off-by: Oded Gabbay Reviewed-by: Alex Deucher List of files: /linux-6.15/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager_cik.c
