https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209430 Bug ID: 209430 Summary: dev.cpu.0.freq_levels are completely bogus on AMD APU Product: Base System Version: 10.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: info@dressmaker.ca CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org For AMD APU A10-6800K powerd reports: dev.cpu.0.freq_levels: 4100/20802 3800/15963 3325/13967 3200/10235 2800/8955 2600/6400 2275/5600 2000/4015 1750/3513 1500/3011 1250/2509 1000/2007 750/1= 505 500/1003 250/501 In reality this APU only supports the following P-States: P-State FID 0x1C - VID 0x12 - IDD 19 (22.00x - ) P-State FID 0x1B - VID 0x18 - IDD 21 (21.50x - ) P-State FID 0x1A - VID 0x20 - IDD 19 (21.00x - ) P-State FID 0x19 - VID 0x26 - IDD 16 (20.50x - ) P-State FID 0x16 - VID 0x34 - IDD 13 (19.00x - ) P-State FID 0x10 - VID 0x46 - IDD 9 (16.00x - ) P-State FID 0xA - VID 0x58 - IDD 6 (13.00x - ) P-State FID 0x4 - VID 0x68 - IDD 4 (10.00x - )=20 i.e. the range of possible frequencies must be from 2000 Mhz to 4400 Mhz and the top 3 are turbo-boost so cannot be set in OS. So it is 4100, 3800, 3600, 3200, 2600, 2000. --=20 You are receiving this mail because: You are on the CC list for the bug.=
