[Intel-gfx] Sandy Bridge: Return of the running fan issue
Dear list, I've previously had an issue with my Dell Laptop (Latitude E5520) which has a i915 graphics card on a Sandy Bridge (2011-12-13 Fan running with Intel Graphics). The fan was running because apparently the GPU was not going into powersave mode. Now, by sheer stupidity on my part, I've lost my kernel configuration and the (working) kernel image. So I embarked on the journey to retrieve the latest git and see how it goes. Sadly, the running fan is back: I've checked out drm-intel-testing, rev. c3c3d4e9. My kernel command line looks like this: pcie_aspm=force i915.i915_enable_rc6=3 i915.lvds_downclock=1 i915.i915_enable_fbc=1 nomodeset Previously, I've always done echo 400 /sys/kernel/debug/dri/0/i915_max_freq but with this kernel revision, /sys/kernel/debug/dri/ is empty and there's no i915_max_freq node anywhere to be found within /sys. Should I update to a different branch? Should I change the kernel command line? Or are there other options? Any advice is greatly appreciated, All the best, Joe ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
[Intel-gfx] Stupid question: Latest GIT repository?
Hi list, sorry for this question, but I'm puzzled and cannot figure out the correct answer: What is actually the most recently updated GIT repository? I'd like to try a newer version (had previously issues with sleeping on Sandy Bridge). Keith's repository (which is referred to by the website) has on the drm-intel-fixes branch its latest commit from 2012-03-07. Eugeni's repository is on the 3.2-stable branch from 2012-02-08, on the rc6 branch (which is something I'm interested in, especially 1c9b22f81) from 2012-01-03. However on the mailing list I frequently see patches -- but I really have no clue where they go :-/ So again sorry for this stupid question, but could somebody please point out where the new stuff goes? Best regards, Johannes ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx

Also, note that by some weird reason intellinuxgraphics.org sometimes lists its pages as unchanged if you have it in your cache. So if it still shows Keith's repo there, just reload it with shift-reload :). Aaaah, indeed that was the problem. I'm very sorry for the confusion. Happily cloning the new repo now, the link now correctly points to Daniel's repository :-) Best regards, Joe ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx

I completely missed the drm-intel-next branch and wondered :-/ Now that I have it running and decelerated the graphics card speed, the system runs in perfect silence. Thank you SO much. It's absolutely fantastic that Intel is supporting Linux so beautifully. Finally Linux users aren't stuck to using solely Nvidia cards. Brings a tear to the eye!

And also check with powertop about what is using the most power out there? Well, temperature as read by coretemp is around 60°C for the CPU, which appears to be quite high for a completely idle device. There seems to be some second sensor that I'm unable to read out which controls the fan, however. powertop seems nice -- but I have no clue on how to read it actually. Or how to get to know what power which process actually draws. I can just see that by far the application with the highest Usage is the X server (around 10 times that of the second largest, which usually is 7,1 ms/s 50,2Process/usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none 453,5 µs/s 19,9Interrupt [6] tasklet(softirq) But since I have no clue on how to read those values, they mean next to nothing to me. On the Idle Stats page, the CPU is 99.8% of the time in C7 mode. The frequency stats show the CPU is clocked at 800Mhz (the lowest setting). The Device Stats also mean little to me: It looks like a part of lspci (with always 100% usage), i.e. 100,0%Radio device: btusb 100,0%USB Device: usb-device-8087-0024 100,0%USB device: DW375 Bluetooth Module (Dell Computer Corp) 100,0%PCI Device: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller 100,0%Radio device: dell-laptop 100,0%Radio device: dell-laptop 100,0%Radio device: iwlagn 100,0%PCI Device: Intel Corporation 2nd Generation Core Processor Family DRAM Controller 100,0%PCI Device: Intel Corporation Centrino Advanced-N 6205 100,0%PCI Device: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 100,0%PCI Device: O2 Micro, Inc.

[Intel-gfx] Fan running with Intel Graphics
Hi list, I hope that this is the right place to come. I have a Dell Latitude E5520 Laptop (Sandy Bridge, Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz) and I'm using the Intel graphics driver that ships with Ubuntu (3.0.0 kernel): joelaptop [~]: lspci -nn | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) joelaptop [~]: dpkg -l | grep xorg | grep int ii xserver-xorg-video-intel 2:2.15.901-1ubuntu2.1 X.Org X server -- Intel i8xx, i9xx display driver I have one problem with this setup, however: The fan is running all the time. It annoys the shit out of me. The reason why I suspect that something might be off with the graphics card driver is that in framebuffer mode, the fan is off. Only when I type in the password to my cryptofs (which leaves the framebuffer and starts Xorg) the fan starts running almost instantaniously. And it's not even doing *anything*, the CPUs are all at almost 0% (therefore I don't think there's much heat coming from there). I'm not doing heavy graphics (not even light graphics, not even moving the mouse!). How can I measure the graphics card load? Would it improve anything if I compiled a kernel myself and switched to 3.1? Is there anything at all I can do?
