From: Ray Wu <[email protected]> [Why] Users can access the replay residency to get PHY off percentage
[How] Start capture residency: sudo echo 1 /sys/kernel/debug/dri/0/eDP-1/replay_residency Stop and Get replay residency: sudo cat /sys/kernel/debug/dri/0/eDP-1/replay_residency Reviewed-by: ChiaHsuan (Tom) Chung <[email protected]> Signed-off-by: Ray Wu <[email protected]> Signed-off-by: Ivan Lipski <[email protected]> --- .../amd/display/amdgpu_dm/amdgpu_dm_debugfs.c | 34 ++++++++++++++++++- 1 file changed, 33 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c index 484691335fd6..f263e1a4537e 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c @@ -3106,6 +3106,35 @@ static int replay_get_state(void *data, u64 *val) return 0; } +/* + * Start / Stop capture Replay residency + */ +static int replay_set_residency(void *data, u64 val) +{ + struct amdgpu_dm_connector *connector = data; + struct dc_link *link = connector->dc_link; + bool is_start = (val != 0); + u32 residency = 0; + + link->dc->link_srv->edp_replay_residency(link, &residency, is_start, PR_RESIDENCY_MODE_PHY); + return 0; +} + +/* + * Read Replay residency + */ +static int replay_get_residency(void *data, u64 *val) +{ + struct amdgpu_dm_connector *connector = data; + struct dc_link *link = connector->dc_link; + u32 residency = 0; + + link->dc->link_srv->edp_replay_residency(link, &residency, false, PR_RESIDENCY_MODE_PHY); + *val = (u64)residency; + + return 0; +} + /* * Read PSR state */ @@ -3325,7 +3354,8 @@ DEFINE_DEBUGFS_ATTRIBUTE(dmcub_trace_event_state_fops, dmcub_trace_event_state_g dmcub_trace_event_state_set, "%llu\n"); DEFINE_DEBUGFS_ATTRIBUTE(replay_state_fops, replay_get_state, NULL, "%llu\n"); - +DEFINE_DEBUGFS_ATTRIBUTE(replay_residency_fops, replay_get_residency, replay_set_residency, + "%llu\n"); DEFINE_DEBUGFS_ATTRIBUTE(psr_fops, psr_get, NULL, "%llu\n"); DEFINE_DEBUGFS_ATTRIBUTE(psr_residency_fops, psr_read_residency, NULL, "%llu\n"); @@ -3503,6 +3533,8 @@ void connector_debugfs_init(struct amdgpu_dm_connector *connector) debugfs_create_file("replay_capability", 0444, dir, connector, &replay_capability_fops); debugfs_create_file("replay_state", 0444, dir, connector, &replay_state_fops); + debugfs_create_file_unsafe("replay_residency", 0444, dir, + connector, &replay_residency_fops); debugfs_create_file_unsafe("psr_capability", 0444, dir, connector, &psr_capability_fops); debugfs_create_file_unsafe("psr_state", 0444, dir, connector, &psr_fops); debugfs_create_file_unsafe("psr_residency", 0444, dir, -- 2.43.0
