While video streaming when we try to do XO-SD using the command "echo mem > /sys/power/state command" , device is not entering to suspend state and from interconnect summary seeing votes for venus0-ebi Corrected this by voting for venus0-ebi path in venus_runtime_resume() and unvote during venus_runtime_suspend(). suspend") Fixes: 07f8f22a33a9e ("media: venus: core: remove CNOC voting while device Signed-off-by: Mansur Alisha Shaik Reviewed-by: Stephen Boyd Signed-off-by: Stanimir Varbanov Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Sasha Levin --- drivers/media/platform/qcom/venus/core.c | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-) diff --git a/drivers/media/platform/qcom/venus/core.c b/drivers/media/platform/qcom/venus/core.c index 52a3886..fa363b8 100644 --- a/drivers/media/platform/qcom/venus/core.c +++ b/drivers/media/platform/qcom/venus/core.c @@ -363,7 +363,18 @@ static __maybe_unused int venus_runtime_suspend(struct device *dev) ret = icc_set_bw(core->cpucfg_path, 0, 0); if (ret) - return ret; + goto err_cpucfg_path; + + ret = icc_set_bw(core->video_path, 0, 0); + if (ret) + goto err_video_path; + + return ret; + +err_video_path: + icc_set_bw(core->cpucfg_path, kbps_to_icc(1000), 0); +err_cpucfg_path: + pm_ops->core_power(dev, POWER_ON); return ret; } @@ -374,6 +385,10 @@ static __maybe_unused int venus_runtime_resume(struct device *dev) const struct venus_pm_ops *pm_ops = core->pm_ops; int ret; + ret = icc_set_bw(core->video_path, 0, kbps_to_icc(1000)); + if (ret) + return ret; + ret = icc_set_bw(core->cpucfg_path, 0, kbps_to_icc(1000)); if (ret) return ret; -- 2.7.4
