Nightwulf|work: hi all
yangman: libv: if you'd like commit history for my powerplay patch, I can put my repo up somewhere or push it myself
libv: yangman: commit history would be nice, you can also do this through git-format-patch
libv: and then send off the whole list
libv: or url for a git repo
yangman: right, git-format-patch. I knew git had something like that, but couldn't remember what it was called
yangman: libv: just packaging all the patch files into a tarball is fine?
libv: or you could just attach them as well, whatever suits you
libv: yangman: thanks
V4Nelle: guys can i have 3d accel on radeonhd?
Zajec: goole + radeonfeature + first result
zooko: Folks: my radeonhd 2400 fails to detect a connected monitor when I have only a DVI cable connecting it.
zooko: It works when I have an old analog cable, but then it looks crummy.
zooko: Also, my wife just borrowed my analog cable, so now I am in text mode. :-)
zooko: Does anyone know how to configure it differently so that it detects the monitor connected by DVI, or perhaps does someone know that this is a bug that has been fixed and I should try upgrading my radeonhd driver?
yangman: zooko: you should upgrading
yangman: *try upgrading
zooko: This is just generic advice, right? ;-)
zooko: Do you have any knowledge that there was such a bug in...
zooko: I think I'm running radeonhd 1.2.1.
zooko: Should I use git or something to get the latest version, and if so from what git URL?
yangman: if you're running 1.2.1 proper, that's definitely too old
zooko: Hm, " * Fixed several modesetting, RandR, save/restore, and connector table
zooko: Could a "connector table bug" explain my problem?
yangman: the URL in topic has instructions for fetching from git
yangman: I don't remember the exact bug, but it was reported and, iirc, fixed
zooko: Heh. Doesn't compile.
zooko: rhd_helper.c: In function 'RhdAssertFailed':
zooko: rhd_helper.c:209: error: implicit declaration of function 'kill'
ndim: zooko: Linux?
Zajec: i have sollution...
zooko: Hooray! Reverting to the radeonhd 1.1.0 that comes with ubuntu hardy fixed it!
Zajec: Anders just noticed that problem with kill function: http://lists.opensuse.org/radeonhd/2008-10/msg00017.html
zooko: Thanks for the help, folks!
zooko: Okay, back to work on Tahoe.
ndim: Tahoe? "Tattery Tahoe", the next Ubuntu release?
yangman: or.. the truck?
yangman: T is quite a way away ;)
ndim: Oh right. Rabid Rascal will be first.
Temujin_: hi, i tried to build the latest master branch code with sudo git pull and am now receiving errors when i try to make
Temujin_: rhd_helper.c:209: error: 'SIGSEGV' undeclared (first use in this function)
Temujin_: rhd_helper.c:209: error: implicit declaration of function 'kill'
Temujin_: the last sudo git pull i did (about a week ago) built fine
yangman: Temujin_: try rerunning autogen.sh
Zajec: Temujin_ http://lists.opensuse.org/radeonhd/2008-10/msg00017.html
Zajec: Temujin_: something about config :|
Temujin_: yangman, i just ran it before doing the make
Temujin_: but i'll try again
Temujin_: same errors
yangman: hm.. looks like it's because of the latest commit
yangman: if you just want to test the powerplay patch, an older master will actually work
Temujin_: yeah, Zajec's suggestion worked
Temujin_: no powerplay, i just like to keep the driver updated :)
Temujin_: and wanted to report the error
yangman: ah. I just saw a message to the ML. I guess it's not you, then :)
Zajec: yangman: thanks for explaining PowerPlay on ML
yangman: np. I was hoping someone else with a r600 could take up that portion, actually
yangman: but I guess we'll all jus thave to wait
yangman: from the register docs, though, R600+ PM looks way, way cleaner
yangman: it may just turn out to be turning on a few bits, and the hardware doing the rest
Zajec: I know quite nothing about low level programming...
Zajec: What does rhd_dump do?\
Zajec: Does it read just some part of memory? Am I right?
yangman: the driver has to map parts of the GPU to system memory so it can access it. rhd_dump does the same thing. it lets you read and write the mapped memory
yangman: and a portion of the map corresponds to registers that controls things
Zajec: Can I use it to map and read some not-GPU releated memrory?
Zajec: I wish to understand how WIndows driver decreases backlight
yangman: I don't think you can. it's a very specific tool
Zajec: Uhm, ok
Zajec: Is there something similar I could use?
Zajec: Something that reads ACPI-related memory?
yangman: I don't know much about how ACPI is implemented. I hear it's a huge mess, though
Zajec: Not optimistic
yangman: in any case, backlight for laptops tend to be a minefield.
yangman: it'll be not too hard, and someone's already figured out how, or near impossible
yangman: have you tried working with radeonhd's backlight code?
Zajec: what do you mean by this?
Zajec: does radeonhd provide something to controll backlight?
yangman: through xrandr
yangman: this was added way back because the way it initialized the hardware meant BIOS backlight control wouldn't work
yangman: if you do xrandr --prop you should see a BACKLIGHT property under the PANEL output
yangman: try adjusting this and see if it does anything
Zajec: i can see that in --prop
Zajec: Just tried xrandr --output PANEL --set BACKLIGHT 1
Zajec: doesn't work :|
Zajec: nor "100" or "200
yangman: yeah, it's not reliable
Zajec: should I report as bug?
Zajec: using 100% backlight eats my battery just great :P
yangman: the vt-switch trick might work for you
yangman: switch to a different VT, change the brightness there, then switch back to VT7
yangman: depends on your hardware, though
Zajec: how to switch in other VT? using xrandr or other method?
Zajec: *how to change in other VT
Zajec: sorry :)
yangman: 7 is the VT X starts on by default
Zajec: ctrl+alt+F1 and what then? xrandr?
yangman: no, hitting the brightness adjustments on your laptop
Zajec: something like Fn+F5/F6?
Zajec: doesn't work ;/
Zajec: also Fn+F5/F6 doesn't work at BIOS booting stage
yangman: in that case, you have a software-controlled backlight
yangman: so, you gotta figure out if it's even possible at all under linux
Zajec: any way doing that?
yangman: google :)
Zajec: it's quite new notebook, nobody solved that yet
Zajec: it was published about 1-2 months ago
yangman: what is it?
Zajec: Sony Vaio FW11
Zajec: sony-laptop kernel module doesn't support it
yangman: yeah, Sonys are... difficult, in general
Zajec: video acpi kernel module doesn't support also
Zajec: do you think it's possible to make dump of memory in Linux, switch to native Windows, change backlight, switch to Linux and compare dump with current state? is thath the way?
yangman: well, you have to reboot between those steps, which reinitializes the hardware
yangman: and you don't know what to map, much less if it's mappable
Zajec: damn ;/
yangman: just gotta wait until someone figures it out
Zajec: i'm afraid noone will
Obscene_CNN: heh, I just got back from the optician.... She is sick of everybody wanting Sarah Palin glasses
Obscene_CNN: she said its almost as bad as when everyone wanted Harry Potter glasses
lupine_85: :s :S
lupine_85: contact lenses, grasshopper
agd5f: there's an atom method for adjusting the backlight. the problem is, the backlight can be controlled by a number of methods depending on how the oem decides to wire up the backlight
agd5f: generally the best bet is acpi
