Kano: Host/Kernel/OS "Kanotix" running Linux 2.6.30-4-generic i686 [ Kanotix Excalibur 20090506-17:27 ]
Kano: CPU Info (1) Intel Core2 Duo E8400 @ clocked at [ 1999.000 MHz ]
Kano: (2) Intel Core2 Duo E8400 @ clocked at [ 2999.000 MHz ]
Kano: Videocard ATI Mobility Radeon HD 3450 X.Org 1.4.2 [ 1680x1050 ]
Kano: Processes 143 | Uptime 5min | Memory 258.1/1977.9MB | HDD Size 1000GB (6%used) | GLX Renderer ATI Radeon HD 3450 | GLX Version 2.1.8591 | Client Konversation 1.1 | Infobash v2.67.1
Kano: got fglrx running, but needed one additional export in the kernel
maligor_: Kano, does it spam dmesg with errors?
Kano: well it does ;)
Kano: you have got a better fix for this
maligor: the internal corruption?
maligor: I was hoping you might've found one :P
Kano: [fglrx:firegl_find_any_map] *ERROR* Invalid map handle!<3>[fglrx:drm_vm_close] *ERROR* map not found -> inconsistent kernel data!!! vma_start:0xb7f7a000,handle:0xd0100000
Kano: thats what you mean i think
maligor: that's the reason I'm using 2.6.28
Kano: it doesnt happen always it seems
Kano: only when 3d is used, then 2 lines or so
maligor: I'd love to switch to 2.6.30 since it supports the monitor chip on this asus board
maligor: or rather the acpi junk that controls the chip
Kano: buy nvidia ;)
Kano: i fixed all drivers
Kano: pretty simple patch btw
maligor: you mean the acpi fix for fglrx?
Kano: no, all legacy nvidia ;)
maligor: oh, right
maligor: I'll probably just move to opensource driver once it runs s2
Kano: i want to see an oss driver that run gl2benchmark + zero ballistics
Kano: those require glsl
maligor: might have to wait for the famous gallium3d then
Kano: do you know what fglrx do the whole day? as i heard that 9-5 will not even support 2.6.29...
Kano: http://nvnews.net/vbulletin/showthread.php?t=131872
Kano: hat patch for 96.11.43 works with any legacy driver btw. i just did a similar patchwith kernel version checking instead of removing code
Kano: maligor: i would go for 2.6.30, the dmesg errors does not seem to affect speed
Kano: only 2 on 3d game start, 1 at end...
evocallaghan: michaellarabel: Hi, btw, AuroraUX is using llvm-gcc as its default compiler. So, yes a number of projects are switching over, DragonflyBSD can compile using clang/llvm as well.
Rooster99991: anyone here work in the datacenter/hosting field? Looking for tips on what to know/study for an interview
peppo: how to load maps in Sauerbraten?
peppo: I can't type in console...
Lightkey: peppo: ask in #freegamer
peppo: -lMAP
elena09: hi
elena09: no one here?
mether: elena09: if you got something to say or ask, just do that
elena09: a second please, I did a test...
elena09: phoronix-test-suite default-benchmark graphics-magick c-ray unigine
elena09: sorry
elena09: phoronix-test-suite default-benchmark graphics-magick c-ray unigine
elena09: what does this test exactly?
mether: michaellarabel: would know elena09
elena09: I mean, the temperature of my GPU reached 61 Celsius, but the rest of components stayed pretty cool
elena09: I installed lm sensors in Ubuntu
michaellarabel: elena09: It runs two CPU and a GPU test
elena09: is there a more complete test, around 1 hour length , which could test CPU, GPU, Sound, cooling system and HDD and which really overheats the laptop?
Ivanovic: elena09: how to test if sound overheats the laptop?
Ivanovic: sure, cpu has sensors, so (maybe) has the gpu
gzed: heh
Ivanovic: *some* hdds might have strange sensors, though most likely not temperature
Ivanovic: (at least not in normal laptops i'd guess)
elena09: I was reffering to the test, it should overheat the laptop and also test everything else, including sound
Ivanovic: elena09: if your laptop overheats you should remove dust from it
Ivanovic: (that is a *very* common issue for laptops!)
Azerthoth: or buy something other than an HP
elena09: I don't have any laptop, I want to buy one, but before of that I had to test it
elena09: HP? Why?
Ivanovic: ugh, this is *difficult* as hell...
Azerthoth: mine ran hot from the day I bought it, only a cool pad has helped keep it alive
elena09: do you have a HP?
Ivanovic: is really satisfied with his lenovo x60t (though it is probably more expensive than many are willing to pay)
elena09: Ivanovic, do you run Ubuntu on it?
Ivanovic: that is: i can easily handle the fan myself (and yeah, i "reimplemented" fancontrol via a bashscript
Ivanovic: no, i run gentoo on it
Ivanovic: (for my taste the fan was starting at too low temperatures, so i wrote a (very simple) check for cpu temp and set the fan to "auto" if the temperature value i wanted as max is broken, once temperature is below the threashols again, fan is turned off)
elena09: http://ubuntuforums.org/showthread.php?t=311158
elena09: That's a real test
Ivanovic: this way the fan is completely off while i just surf, read, whatever and only when doing something more demanding it is activated
elena09: It made a friend's laptop to shutdown, like 75 Celsius
Ivanovic: muhaha, the kernel is rather harmless, there are wrose things than the kernel
Ivanovic: especially as described in this howto since it only uses one thread at compiling
Ivanovic: (in modern multicore systems it would only use one cpu, lots of wasted time is the result since compiling the kernel is easy to parallize)
Ivanovic: "The kernel will now compile for 1-3 hours, depending on the speed of your processor"
Ivanovic: that is a joke, right?
Ivanovic: (IIRC on my system (yeah, even the laptop) it only takes about 10 to 20 mins to build the kernel)
Ivanovic: lets run the PTS test for building the kernel on my desktop machine...
Ivanovic: (though this is unfair to run >1 time since ccache will destroy the results in run 2 and 3)
Azerthoth: and it's oh so hard to turn ccache back off
Azerthoth: *grin*
Ivanovic: Azerthoth: it ends in work since in my path the ccache "gcc" is as extra folder and i would have to hack around in my $PATH settings which is work
Ivanovic: useless work that is
Azerthoth: odd, guess I never needed that level of tweaking, I just remove it from FEATURES and it magically fails
Ivanovic: Azerthoth: ehm, i am running pts in my user account
Azerthoth: ran into a few times where ccache caused me issues
Ivanovic: and i also compile outside of portage
Ivanovic: ;)
Ivanovic: (that is where i mainly use ccache, eg for compiling wesnoth, where it *really* helps)
Azerthoth: ah, I solved the wesnoth problem a different way
Azerthoth: then ran into a subsequent world of goo problem to replace the wesnoth one
Ivanovic: the "wesnoth problem" is no problem, it is just that i am a dev and compile a little differently than a normal "gentoo enduser"
Ivanovic: ;)
Azerthoth: I had to stop playing, I was never getting anything done
Ivanovic: elena09: okay, i just checked with the 2.6.25 kernel, extracting it, running a plain "make menuconfig" to generate a config and then benchmarked compile time via "time { make -j5; }" (before this i ran "ccache -C" to make sure that nothing is cached)
Ivanovic: here is the output from time:
Ivanovic: real 1m42.113s
Ivanovic: user 4m54.138s
Ivanovic: sys 0m42.950s
Ivanovic: a benchmark running only 2mins on a "modern era" system is not too much stress to really be able to *overheat* the box
Ivanovic: yes, it places some stress and is able to get temperatures up for a short time, but to make it really unstable you most likely need more
Ivanovic: Sysinfo for 'rechner1': Linux 2.6.29.1 running , CPU: Intel(R) Core 2 Quad CPU Q9300 @ 2.50GHz at 2000 MHz (4999 bogomips), HD: 463/1162GB, RAM: 2351/3952MB, 158 proc's, 4.29h up
elena09: good night
