hwpstate0: set freq failed, err 6 The cpufreq works as I can seen in kernel messages with hwpmc.ko loaded: hwpstate0: going to fetch info from acpi_perf hwpstate0: <Cool`n'Quiet 2.0> on cpu0 hwpmc: TSC/1/64/0x20<REA> K8/4/48/0x1ff<INT,USR,SYS,EDG,THR,REA,WRI,INV,QUA> and I get the sysctl variables: dev.cpu.0.freq: 1400 dev.cpu.0.freq_levels: 3100/14210 2800/12250 2450/10718 2300/8677 2012/7592 1900/5431 1662/4752 1425/4073 1400/3558 1225/3113 1050/2668 875/2223 700/1779 525/1334 350/889 175/444 I also test to set "hint.acpi_throttle.0.disabled=1" in boot/loader.conf, but this only reduce the frequency dev.cpu.0.freq_levels: 3100/14210 2800/12250 2300/8677 1900/5431 1400/3558 that's exactly the same what dev.hwpstate.0.freq_settings: 3100/14210 2800/12250 2300/8677 1900/5431 1400/3558 have. But the error is still there. So I try "debug.hwpstate_verbose=1" and get now hwpstate0: setting P1-state on cpu0 hwpstate0: result P0-state on cpu0 hwpstate0: error: loop is not enough. hwpstate0: setting P1-state on cpu1 hwpstate0: result P1-state on cpu1 hwpstate0: setting P1-state on cpu2 hwpstate0: result P0-state on cpu2 hwpstate0: error: loop is not enough. hwpstate0: setting P1-state on cpu3 hwpstate0: result P1-state on cpu3 hwpstate0: setting P1-state on cpu4 hwpstate0: result P0-state on cpu4 hwpstate0: error: loop is not enough. hwpstate0: setting P1-state on cpu5 hwpstate0: result P1-state on cpu5 hwpstate0: setting P1-state on cpu6 hwpstate0: result P0-state on cpu6 hwpstate0: error: loop is not enough. hwpstate0: setting P1-state on cpu7 hwpstate0: result P1-state on cpu7 hwpstate0: set freq failed, err 6 and so on. Then I try to increase the loop in "src/sys/x86/cpufreq/hwpstate.c" without success. I don't have any Idee now to fix. May something is missing in the hwpmc code for the CPU or is this only a result from a buggy bios with incomplete acpi cpu code? Can anybody confirm that the powerd is working correctly with this CPU on an other Mainboard than the MSI 870A-G54 (FX)? >How-To-Repeat: Start powerd with an AMD 8 Core FX 8120 CPU >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
