Bring back a set of patches extracted from [1] per Abhinav's suggestion. Rework debugging overrides for the bandwidth and clock settings. Instead of specifying the 'mode' and some values, allow one to set the affected value directly. [1] https://patchwork.freedesktop.org/series/119552/#rev2 Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx> --- Changes in v5: - Fixed bps -> KBps in the comments (Abhinav) - Split the core_clk_rate changes into a separate commit (Abhinav) - Expanded commit message to note that debugfs bandwidth settings are not a subject to catalog thresholds (Abhinav) - Temporarily dropped the patches actually reworking the debugfs modes, they will be reposted separately. - Link to v4: https://lore.kernel.org/r/20250106-dpu-perf-rework-v4-0-00b248349476@xxxxxxxxxx Changes in v4: - Dropped core_perf: from patch subject (Abhinav) - Fixed indentation of _dpu_core_perf_crtc_update_bus() (Abhinav) - Expanded commit messages to reflect different questions (Abhinav) - Reworked existing files to specify max allowed average bandwidth (Abhinav) - Fixed u32 vs u64 and KBps vs Bps values in debugfs interface - Link to v3: https://lore.kernel.org/r/20240314-dpu-perf-rework-v3-0-79fa4e065574@xxxxxxxxxx --- Dmitry Baryshkov (8): drm/msm/dpu: extract bandwidth aggregation function drm/msm/dpu: remove duplicate code calculating sum of bandwidths drm/msm/dpu: change ib values to u32 drm/msm/dpu: make fix_core_ab_vote consistent with fix_core_ib_vote drm/msm/dpu: also use KBps for bw_ctl output drm/msm/dpu: rename average bandwidth-related debugfs files drm/msm/dpu: drop core_clk_rate overrides from _dpu_core_perf_calc_crtc drm/msm/dpu: handle perf mode in _dpu_core_perf_crtc_update_bus() drivers/gpu/drm/msm/disp/dpu1/dpu_core_perf.c | 140 ++++++++++++-------------- drivers/gpu/drm/msm/disp/dpu1/dpu_core_perf.h | 10 +- drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 5 +- 3 files changed, 71 insertions(+), 84 deletions(-) --- base-commit: ed58d103e6da15a442ff87567898768dc3a66987 change-id: 20240314-dpu-perf-rework-97fca999eb46 Best regards, -- Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>
