https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233693 Bug ID: 233693 Summary: [PowerPC64] Powerd unable to change cpu frequency Product: Base System Version: CURRENT Hardware: powerpc OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: sbruno@FreeBSD.org The Tyan Power8 machines seem to need some kind of tweak to allow any powerd functionality. Starting powerd simply emits this repeatedly on the console: pmcr0: set freq failed, err 22 pmcr1: set freq failed, err 22 pmcr2: set freq failed, err 22 pmcr3: set freq failed, err 22 pmcr0: set freq failed, err 22 pmcr1: set freq failed, err 22 pmcr2: set freq failed, err 22 pmcr3: set freq failed, err 22 pmcr(8) seems to be detecting the following: root@pylon.nyi:~ # sysctl dev.pmcr dev.pmcr.3.freq_settings: 4322/-1 4289/-1 4256/-1 4222/-1 4189/-1 4156/-1 4123/-1 4089/-1 4056/-1 4023/-1 3990/-1 3956/-1 3923/-1 3890/-1 3857/-1 382= 3/-1 3790/-1 3757/-1 3724/-1 3690/-1 3657/-1 3624/-1 3591/-1 3557/-1 3524/-1 349= 1/-1 3458/-1 3424/-1 3391/-1 3358/-1 3325/-1 3291/-1 3258/-1 3225/-1 3192/-1 315= 8/-1 3125/-1 3092/-1 3059/-1 3025/-1 2992/-1 2959/-1 2926/-1 2892/-1 2859/-1 282= 6/-1 2793/-1 2759/-1 2726/-1 2693/-1 2660/-1 2626/-1 2593/-1 2560/-1 2527/-1 249= 3/-1 2460/-1 2427/-1 2394/-1 2360/-1 2327/-1 2294/-1 2261/-1 2227/-1 2194/-1 216= 1/-1 2128/-1 2094/-1 2061/-1 dev.pmcr.3.%parent: cpu3 dev.pmcr.3.%pnpinfo:=20 dev.pmcr.3.%location:=20 dev.pmcr.3.%driver: pmcr dev.pmcr.3.%desc: Power Management Control Register dev.pmcr.2.freq_settings: 4322/-1 4289/-1 4256/-1 4222/-1 4189/-1 4156/-1 4123/-1 4089/-1 4056/-1 4023/-1 3990/-1 3956/-1 3923/-1 3890/-1 3857/-1 382= 3/-1 3790/-1 3757/-1 3724/-1 3690/-1 3657/-1 3624/-1 3591/-1 3557/-1 3524/-1 349= 1/-1 3458/-1 3424/-1 3391/-1 3358/-1 3325/-1 3291/-1 3258/-1 3225/-1 3192/-1 315= 8/-1 3125/-1 3092/-1 3059/-1 3025/-1 2992/-1 2959/-1 2926/-1 2892/-1 2859/-1 282= 6/-1 2793/-1 2759/-1 2726/-1 2693/-1 2660/-1 2626/-1 2593/-1 2560/-1 2527/-1 249= 3/-1 2460/-1 2427/-1 2394/-1 2360/-1 2327/-1 2294/-1 2261/-1 2227/-1 2194/-1 216= 1/-1 2128/-1 2094/-1 2061/-1 dev.pmcr.2.%parent: cpu2 dev.pmcr.2.%pnpinfo:=20 dev.pmcr.2.%location:=20 dev.pmcr.2.%driver: pmcr dev.pmcr.2.%desc: Power Management Control Register dev.pmcr.1.freq_settings: 4322/-1 4289/-1 4256/-1 4222/-1 4189/-1 4156/-1 4123/-1 4089/-1 4056/-1 4023/-1 3990/-1 3956/-1 3923/-1 3890/-1 3857/-1 382= 3/-1 3790/-1 3757/-1 3724/-1 3690/-1 3657/-1 3624/-1 3591/-1 3557/-1 3524/-1 349= 1/-1 3458/-1 3424/-1 3391/-1 3358/-1 3325/-1 3291/-1 3258/-1 3225/-1 3192/-1 315= 8/-1 3125/-1 3092/-1 3059/-1 3025/-1 2992/-1 2959/-1 2926/-1 2892/-1 2859/-1 282= 6/-1 2793/-1 2759/-1 2726/-1 2693/-1 2660/-1 2626/-1 2593/-1 2560/-1 2527/-1 249= 3/-1 2460/-1 2427/-1 2394/-1 2360/-1 2327/-1 2294/-1 2261/-1 2227/-1 2194/-1 216= 1/-1 2128/-1 2094/-1 2061/-1 dev.pmcr.1.%parent: cpu1 dev.pmcr.1.%pnpinfo:=20 dev.pmcr.1.%location:=20 dev.pmcr.1.%driver: pmcr dev.pmcr.1.%desc: Power Management Control Register dev.pmcr.0.freq_settings: 4322/-1 4289/-1 4256/-1 4222/-1 4189/-1 4156/-1 4123/-1 4089/-1 4056/-1 4023/-1 3990/-1 3956/-1 3923/-1 3890/-1 3857/-1 382= 3/-1 3790/-1 3757/-1 3724/-1 3690/-1 3657/-1 3624/-1 3591/-1 3557/-1 3524/-1 349= 1/-1 3458/-1 3424/-1 3391/-1 3358/-1 3325/-1 3291/-1 3258/-1 3225/-1 3192/-1 315= 8/-1 3125/-1 3092/-1 3059/-1 3025/-1 2992/-1 2959/-1 2926/-1 2892/-1 2859/-1 282= 6/-1 2793/-1 2759/-1 2726/-1 2693/-1 2660/-1 2626/-1 2593/-1 2560/-1 2527/-1 249= 3/-1 2460/-1 2427/-1 2394/-1 2360/-1 2327/-1 2294/-1 2261/-1 2227/-1 2194/-1 216= 1/-1 2128/-1 2094/-1 2061/-1 dev.pmcr.0.%parent: cpu0 dev.pmcr.0.%pnpinfo:=20 dev.pmcr.0.%location:=20 dev.pmcr.0.%driver: pmcr dev.pmcr.0.%desc: Power Management Control Register dev.pmcr.%parent: --=20 You are receiving this mail because: You are the assignee for the bug.=
