Hi, Thanks to all of Ian, Hajimu, Tino ! Hajimu UMEMOTO wrote > Yes, it is implemented already in the kernel, and it should be done by > the ACPI passive cooling. I guess "ACPI passive cooling" means ACPI is supposed to turn down CPU frequency ? & maybe turn off anything else possible (I need to read http://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface & URLs beyond (PS I added one to FreeBSD page). > It seems to me that your ACPI BIOS has it, and when the temperature of > your CPU become over 90.0C, it will effect. 90 sounds terribly hot, so I compared with my Toshiba Satelite hw.acpi.thermal.tz0._PSV: 107.9C hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 108.9C The plastic under my new HP notebook is too hot to comfortably hold. with top 75% idle hw.acpi.thermal.tz0.temperature: 68.0C kern.acct_chkfreq: 15 kern.timecounter.tc.i8254.frequency: 1193182 kern.timecounter.tc.ACPI-safe.frequency: 3579545 kern.timecounter.tc.HPET.frequency: 14318180 kern.timecounter.tc.TSC.frequency: 1596012059 net.inet.sctp.sack_freq: 2 machdep.acpi_timer_freq: 3579545 machdep.tsc_freq: 1596012059 machdep.i8254_freq: 1193182 dev.cpu.0.freq: 696 dev.cpu.0.freq_levels: 1592/100000 1393/87500 1194/75000 995/62500 796/35457 696/31024 597/26592 497/22160 398/17728 298/13296 199/8864 99/4432 dev.acpi_throttle.0.freq_settings: 10000/-1 8750/-1 7500/-1 6250/-1 5000/-1 3750/-1 2500/-1 1250/-1 dev.powernow.0.freq_settings: 1592/100000 796/35457 dev.powernow.1.freq_settings: 1592/100000 796/35457 > However, I'm not sure why your notebook keeps over heating & crashing.

Please elaborate on 'crashing'? and at what sort of TCP failed, rdist & remote xterms & NFS fail, local mousepad fails. I didnt bother to try for a crash dump. I guessed damage was about to occur. > temperature this occurs? Low 80s I recall. Not sure, I thought that was so high damage would occur, so I just turned off & put an external fan under. I've reverted to default values & started a remote xterm with while (1) sysctl -a | grep temp ; date ; echo ; sleep 10 ; end Before with sysctl -a | grep temp I just got hw.acpi.thermal.tz0.temperature: 68.0C dev.acpi_hp.0.hdd_temperature: 4 after kldload amdtemp I get a lot more temperatures: dev.acpi_hp.0.hdd_temperature: 4 dev.amdtemp.0.%desc: AMD K8 Thermal Sensors dev.amdtemp.0.%driver: amdtemp dev.amdtemp.0.%parent: hostb4 dev.amdtemp.0.sensor0.core0: 51.0C dev.amdtemp.0.sensor0.core1: 49.0C dev.amdtemp.0.sensor1.core0: 58.0C dev.amdtemp.0.sensor1.core1: 56.0C dev.cpu.0.temperature: 57.0C dev.cpu.1.temperature: 57.0C hw.acpi.thermal.tz0.temperature: 66.0C > > dmesg & sysctl etc diagnostics at > > http://berklix.com/~jhs/hardware/hp/pavilion/dm3-1155ea/ > > CPU: AMD Athlon(tm) Neo X2 Dual Core Processor L335 (1595.96-MHz K8-class CPU) > > Origin = "AuthenticAMD" Id = 0x60fb2 Family = f Model = 6b Stepping = 2 > > Almost too much info :) esp. with sysctl -a including the verbose dmesg, > but I noticed a couple of things on a quick skim.

I was when it crashed too often to be useful. accepting values from /etc/defaults/rc.conf but it crashed too much, so my rc.conf is now set to give: /usr/sbin/powerd -a adaptive -b minimum -n minimum > When running on battery can you > monitor power use with acpiconf -i0 to see the actual effect on power > usage of running at various lower freqs? Wow what a nice command ! Design capacity: 57276 mWh Last full capacity: 55544 mWh Technology: secondary (rechargeable) Design voltage: 11100 mV Capacity (warn): 5554 mWh Capacity (low): 0 mWh Low/warn granularity: 555 mWh Warn/full granularity: 555 mWh Model number: 5160 Serial number: Li4402A Type: Li OEM info: Hewlett-Packard State: high Remaining capacity: 100% Remaining time: unknown Present rate: unknown Present voltage: 12375 mV Yes I could do that. I dont see anything that's going to give me instantaneous consumption readings above though, & battery state prediction is generaly not accurate. However, I can do better, I can connect a power meter between wall supply & transformer (battery will be irrelevant if full, not charging) & see how much power is going in. & a temperature probe underneath. (OK, heat emitted by screen I don't care about, (just any heat in chassis, from inefficiency converting for screen), I'll see if I can turn off screen with keys or BIOS) But I guess another way is to hack the ACPI to turn the fan on at lower threshold. ? Maybe I'll have to tweak what I got from acpidump -dt http://berklix.com/~jhs/hardware/hp/pavilion/dm3-1155ea/jhs-hp-pPavilion-dm3-1155ea.asl per: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/acpi-debug.html > I see dev.powernow.0.freq_settings: 1592/100000 796/35457 ie just two > speeds, with dmesg showing: > acpi_throttle0: <ACPI CPU Throttling> on cpu0 > acpi_throttle0: P_CNT from P_BLK 0x410 > powernow0: <PowerNow!

No I haven't. but thanks for tip I found http://people.freebsd.org/~mav/power.pdf In Russian (or some kind of Cyrillic) I only have E & German & French. I'll page through & look at syntax :-) http://people.freebsd.org/~mav/power.prd file power.prd: CDF V2 Document, Little Endian, Os 0, Version: 1.0, Code page: -535 viewed with OpenOffice. whhatever it is, not useful for this. > I also notice only C1 states, but using machdep.idle: amdc1e so I wonder > if you're getting benefit from that? Are there BIOS settings re that? I didnt know what C1 was. Found it: http://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface sysctl -a | grep machdep.idle machdep.idle: amdc1e machdep.idle_available: spin, amdc1e, hlt, acpi, sysctl -d machdep.idle machdep.idle: currently selected idle function sysctl -d machdep.idle_available machdep.idle_available: list of available idle functions Where are you seeing the C1 ? Wkipedia does make C1E sound more desirable.
