Instead of relying on pm.mutex it's better to keep metrics lock so that multiple clients can read data without waiting on other APIs that use pm.mutex.[Quan, Evan] If I understand it correctly, what you wanted to express is touse fine-grained lock instead of cross-grained one to avoid chasing for the same lock.Yes, that was what we did before and that's why we have so many types oflocks. Below are my considerations for this:1. We actually do not have such issue that many APIs/clients chasing for thesame lock. Thus fine-grained locks cannot bring much benefits.Take the metrics_lock here for example. The data protected bymetrics_lock are for those pm sysfs interfaces. Those sysfs interface are not so frequently called. And almost all the time, they are called one after one. So, it's rarely they will chase for the same lock.It's not just sysfs, there are other interfaces like sensors, hwmons etc. Basically, metrics table provides data like GFX activity or throttler status that may be continuously monitored by app layer. So other APIs could suffer. My thought is to just keep metrics under a separate lock and not tie with pm.mutex.[Quan, Evan] I doubt about the guess that "other APIs could suffer if metrics data is continuously polled by app layer". Since according to my previous test(watch -n 0.1 "cat /sys/kernel/debug/dri/0/amdgpu_pm_info") which polled the metrics data every 0.1 second, the smu busy percent was almost not affected.
May be try close to real cases like running some videos/changing resolution and run radeon profile or some monitoring app in the background?
So, even the metric data is polled every second by app layer, that should not enforce much loading on the CPUs and SMU cores. Also, keeping a separate lock for metrics data does not help much with the issue mentioned here(even if there is such). As they(app layer and other APIs) will still chase for another lock(message_lock which is kept) for interaction with SMU.
Yes, only the subsequent steps related to reading table data from VRAM. Other APIs don't need to wait for this. Only thinking about profiling cases, may be I'm overthinking.
Thanks, Lijo
BR EvanThanks, Lijo2. Cross-grained lock can simplify our implementations. It's hard to believe,there is 10+(actually 13 as I counted) different types of locks used in our existing power code.By the cross-grained lock, we can simplify the code and protect us fromsome unintentional dead-locks(I actually run into that several times and it's really tricky).BR EvanThanks, LijoSigned-off-by: Evan Quan <evan.quan@xxxxxxx> Change-Id: Ic75326ba7b4b67be8762d5407d02f6c514e1ad35 --- drivers/gpu/drm/amd/pm/swsmu/amdgpu_smu.c | 1 - drivers/gpu/drm/amd/pm/swsmu/inc/amdgpu_smu.h | 1 - .../gpu/drm/amd/pm/swsmu/smu11/arcturus_ppt.c | 14 +-- .../amd/pm/swsmu/smu11/cyan_skillfish_ppt.c | 10 +- .../gpu/drm/amd/pm/swsmu/smu11/navi10_ppt.c | 112 +++++-------------.../amd/pm/swsmu/smu11/sienna_cichlid_ppt.c | 27 ++--- .../gpu/drm/amd/pm/swsmu/smu11/vangogh_ppt.c | 28 ++--- .../gpu/drm/amd/pm/swsmu/smu12/renoir_ppt.c | 14 +-- .../drm/amd/pm/swsmu/smu13/aldebaran_ppt.c | 23 ++-- .../drm/amd/pm/swsmu/smu13/yellow_carp_ppt.c | 10 +- drivers/gpu/drm/amd/pm/swsmu/smu_cmn.c | 21 +--- drivers/gpu/drm/amd/pm/swsmu/smu_cmn.h | 4 - 12 files changed, 70 insertions(+), 195 deletions(-) diff --git a/drivers/gpu/drm/amd/pm/swsmu/amdgpu_smu.c b/drivers/gpu/drm/amd/pm/swsmu/amdgpu_smu.c index ecbc768dfe2f..f0136bf36533 100644 --- a/drivers/gpu/drm/amd/pm/swsmu/amdgpu_smu.c +++ b/drivers/gpu/drm/amd/pm/swsmu/amdgpu_smu.c @@ -956,7 +956,6 @@ static int smu_sw_init(void *handle) bitmap_zero(smu->smu_feature.allowed, SMU_FEATURE_MAX);
