As I've said, 4.19.x is a nice kernel here. > > > grep -i sched .config_4.19-rc5 > CONFIG_HAVE_UNSTABLE_SCHED_CLOCK=y > CONFIG_CGROUP_SCHED=y > CONFIG_FAIR_GROUP_SCHED=y > CONFIG_RT_GROUP_SCHED=y > CONFIG_SCHED_AUTOGROUP=y > CONFIG_SCHED_OMIT_FRAME_POINTER=y > CONFIG_SCHED_SMT=y > CONFIG_SCHED_MC=y > CONFIG_SCHED_MC_PRIO=y > CONFIG_SCHED_HRTICK=y > # CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL is not set > # CONFIG_CPU_FREQ_GOV_SCHEDUTIL is not set > # IO Schedulers > CONFIG_IOSCHED_NOOP=y > CONFIG_IOSCHED_DEADLINE=y > CONFIG_IOSCHED_CFQ=y > CONFIG_CFQ_GROUP_IOSCHED=y > CONFIG_DEFAULT_IOSCHED="deadline" > CONFIG_MQ_IOSCHED_DEADLINE=y > CONFIG_MQ_IOSCHED_KYBER=y > # CONFIG_IOSCHED_BFQ is not set > CONFIG_NET_SCHED=y > # Queueing/Scheduling > CONFIG_USB_EHCI_TT_NEWSCHED=y > CONFIG_SCHED_INFO=y > CONFIG_SCHED_TRACER=y Really, how come you say "these are your settings"? The settings are, what is actually being used not what has ben compiled-in or I miss anything? What's the coincidence between CONFIG_DEFAULT_IOSCHED="deadline" + CONFIG_IOSCHED_DEADLINE=y and cat /sys/block/sda/queue/scheduler mq-deadline [kyber] bfq none Please see #139 - wee need a list of what is effectively used and not what is actually possible. Bare metal or not. Intel? AMD? hugepages or nor? -- You are receiving this mail because: You are watching the assignee of the bug.
