Gabe, I don't know anything about openSuSE, but I'm guessing you got a build error in acpi_walk_namespace. My patch is based on 2.6.33, and acpi_walk_namespace() grew an extra parameter. If my guess is right, then fixing the patch should be trivial. Just find where we're calling acpi_walk_namespace() and remove one of the three trailing NULL args so you only have 2 of them.

FYI and FWIW, I run openSuSE 11.2 and just about everything works. Here's my summary... - Thermal zone comes online if I have the thermal module load after boot finishes, not sure if ubuntu has the 3 different options for module loading - initrd, boot, and after fs mounted - no fan detected, but I'm guessing either there isn't a controllable fan, but even if there is, my fan regulates properly so I don't care - TurboBoost (I believe) is working, which requires a much longer explanation, which I'll be happy to post separately - multiple battery detection works fine Misc hardware - working w/o tweaks - fan adjusts with temp changes - batteries discharge and charge sequentially - sound card - web cam - microphone - card reader - HDMI audio and video - backlight control soft keys - volume soft keys - wifi/bluetooth soft keys - lock screen soft keys - productivity soft keys (vertically along the left) Misc hardware - working w/small tweak - trackpad works just fine, in fact better than with Windows, does require small hal policy for auto configuring - external display soft-key - works, not sure what the 3 different modes are that it cycles through though, or how to identify them Problems - can't get fglrx to work Seems as though the video card doesn't get reset properly and the /etc/ati/amdpscdb changes everytime the display is started and I can't ever get X to work more than once with fglrx installed. This seems to possibly be ACPI related. - can't get the volume mute soft-key LED to turn off DSDT - I've corrected the DSDT to compile and optimize, however it doesn't alleviate the parse errors. I believe this is due to the order the kernel goes through the DSDT. I theorize either reordering the DSDT will fix it or a patch to the kernel is necessary. -- No fans, thermalzone on HP Envy 15 and HP DV6T Quad https://bugs.launchpad.net/bugs/463940 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 463940] Re: No fans, thermalzone on HP Envy 15 and HP DV6T Quad
The reason is the max Hz in all of the kernel and user space tools is the max Hz while all cores are active. Turbo Boost only comes into effect when running un-parallelized code on only a fraction of the cores. So, I've seen my Envy 15 hit 3.0GHz in Windows, using Intel's Turbo Boost utility, but only during single threaded, heavy activity. Otherwise, if it's multithreaded, the system won't go above 1.6GHz, which is the max Hz as far as the Linux system can tell. So there's some catch-up to be played there. Another hint which leads me to this belief is that PowerTOP doesn't understand how to parse/represent TurboBoost, but the openSolaris version does, they patched it themselves. Running openSolaris, I saw all of the different speeds listed, top to bottom, slowest to fastest, with the last entry changing as demand changed. When I ran the linux version, I see the 931MHz state running at the bottom of the list of speeds, even though the speeds get higher going down the list. Therefor, I believe it to be working properly since my speeds vary, fans vary, etc.. -- No fans, thermalzone on HP Envy 15 and HP DV6T Quad https://bugs.launchpad.net/bugs/463940 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 463940] Re: No fans, thermalzone on HP Envy 15 and HP DV6T Quad
Gabe, I did some research too, and also think that TurboBoost works just fine on this machine. This paper explains why applications like powertop aren't telling the whole story. It's also why looking at /proc/cpuinfo is misleading: http://download.intel.com/design/processor/applnots/320354.pdf I don't think a kernel patch is the right answer. Making the kernel poll every second to show the user that TurboBoost is working seems both wasteful and silly, IMO. Patching powertop would be simple though, and much more appropriate. One final piece of confirmation that TurboBoost is enabled is to look at /proc/cpuinfo: $ cat /proc/cpuinfo | grep flags | grep ida | uniq The flag 'ida' tells you that TurboBoost is working. The formal name for the technology is Intel Dynamic Acceleration, which is what the flag stands for. http://www.lesswatts.org/projects/processor-power/dynamic- acceleration.php Finally, I don't know anything about fglrx.

[Bug 463940] Re: No fans, thermalzone on HP Envy 15 and HP DV6T Quad
Hi Alex, I remember getting 5 SSDTs aside from the DSDT. I think (think!) in one of them the _PPC method was populated with values from somewhere in the system memory. This code was repeated 8 times (for each virtual core). The theory is that CPUT dies early on because it relies on _PPC being defined, which it is not at that stage. Later, _PPC becomes initialized/defined (at least that's what I seem to remember) and CPUT gets parsed fine on subsequent calls. As for F.04, I can confirm the fans were on, stuck on low, but weren't throttling at all. When running with a fixed DSDT (so I could at least get a critical shutdown temperature and thermal zone sensor) the machine got so hot that the critical temperature was triggered and Ubuntu shut down the system. I'm sorry I can't help you anymore than this as I returned my Envy 15. -- No fans, thermalzone on HP Envy 15 and HP DV6T Quad https://bugs.launchpad.net/bugs/463940 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Ivo, Thank you for all the debugging work you've done so far. As of F.06, I can confirm that the fans seem to be throttling correctly. A -j8 kernel build on this machine takes about 15 minutes. Observing the value in /proc/acpi/thermal_zone/TZ01/temperature shows a peak of around 81 C which decreases to 58 C or so after the build is done. I can also physically hear the fans spin up rather high, and then throttle back after the build. I think it's normal for /proc/acpi/fan/ to be empty, so I'm not too concerned about that. I'll take a closer look at the parsing of CPUT and PSSC, as well as the C state oddity.

I'd like to confirm and elaborate on irwjager's recent findings. I allowed the computer to boot unplugged. I then connected the power after booting had completed. Not only are C-states available, but the laptop's CPU temperature at idle is considerably cooler. /proc/acpi/thermal_zone/TZ01/temperature reads 38 C at idle instead of 55 C when booted with the power connected.

It honestly seems like this BIOS was commissioned by a baboon. It should've never passed QA like this. I'm taking my Envy back for a refund. There is only so much time I can spend on debugging something that should just work. To recap our findings so far; * Fans not working (at least on F.04). * Thermal zone/sensors not working. * ACPI parsing aborts in several places due to initialization bugs (Linux does work around this) * CPU Powersaving (aka C-State switching) only works if you boot the machine without AC adapter attached. * No critical shutdown temperature returned for anything else but Windows. In short, this BIOS is a recipe for a cooked CPU: all cores are always awake, all of the time (generating copious amounts of heat). Heat which is insufficiently dissipated by the fans (they don't seem to throttle at any temperature). The OS can't shut down the machine if it gets too hot because it is kept in the dark about 1. the current temperature 2. what temperature is considered critical.

[Bug 463940] Re: No fans, thermalzone on HP Envy 15 and HP DV6T Quad
Abrahm, looking at your DSDT, firmware F.05 solves the thermal zone problem for OS's other than Windows. It also adds a couple of new devices but I'm not sure what they do. Hearing that your fans are actually throttling on F.05 sounds really encouraging. I got no such thing happening on F.04. I strongly suspect the missing _PPC object is due to a timing issue. I believe the SSDT, which loads the _PPC object into the namespace definitions, is loaded way after the parser encounters a reference to the _PPC object. It can't find it, because it doesn't know of it yet, so it throws that namespace error and aborts. It's very sloppy coding. One simple solution would be to put 'If CondRefOf (_PR.CPU0._PPC)' around the code in the DSDT that tries to access it. It basically checks if _PR.CPU0._PPC exists yet. If not, it won't execute the code. Ofcourse, this is only useful if the code is called again later, when the _PPC object has been loaded, at which point it will succeed. I'm thinking this is the case as the code seems to deal with P-States and throttling. Even without a fix, the buggy code in the DSDT is probably enough to make P-States work, as evidenced by Abrahm. As for C-states, it wouldn't surprise me if they simply aren't defined at all in this BIOS.

[Bug 463940] Re: No fans, thermalzone on HP Envy 15 and HP DV6T Quad
I just noticed this too in dmesg; ACPI: EC: Enabling special treatment for EC from MSI. corresponding to this bug; http://www.mail-archive.com/acpi-bugzi...@lists.sourceforge.net/msg26802.html Obviously our HPs aren't MSIs... Also, apologies for attaching the wrong DSDT. I think the one I attached was the first version that actually compiled on iasl (had to do a lot of cleaning up to get there). -- No fans, thermalzone on HP Envy 15 and HP DV6T Quad https://bugs.launchpad.net/bugs/463940 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 463940] Re: No fans, thermalzone on HP Envy 15 and HP DV6T Quad
Ok, instead of altering the DSDT, I modifed ec.c and thermal.c and built
a custom kernel.
I fixed the inappropriate MSI detection (by the way, this should be
fixed for all as of 2.6.32.rc3). I also forced the critical temperature
threshold to a fixed value (3702) which I gleaned from the DSDT, but
only if there is no valid value returned by the BIOS (on the Envy 15,
DV6T there isn't). Now the Thermal Zone init doesn't fail anymore.
Unfortunately, the MSI fix did nothing to get rid of the ACPI parse errors.
The critical temperature threshold fix brought the Thermal Zone on-line.
While looking at the DSDT some more, I noticed a flag called IOSS. I
strongly suspect this flag is set if the (Linux based) Instant-On OS is
booting. Indeed, looking at the ciritical temperature method, it returns
a value if this flag is set, not bothering with any other OS detection.
Method (_CRT, 0, Serialized)
{
If (LEqual (IOSS, One))
{
Return (0x0E76)
}
If (LLess (OSYS, 0x07D6))
{
If (LEqual (TJMX, 0x64))
{
If (LEqual (FSI1, One))
{
Return (0x0E30)
}
Else
{
Return (0x0E76)
}
}
}
}
Conclusion; HP/Insyde have made a special patch for the Linux-based IOS,
but any other Linux distro is screwed!
Does anyone have any ideas on what could be causing the
[\_PR_.CPU0._PPC] namespace lookup failure? What does it mean?
