Nishanth' tech rambles

http://linux.omap.com/pub/kernel/2430sdp/source/ contains the source now.. :) the 2.6.10 code contains the new audio architecture. it works on SDP2430 and H4 (2420) too.. I guess I need to spend a bit of time to put it together for h3,h2,osk before pushing for it... :( and ofcourse.. lotsa fight coming up for the new dma apis for chaining...

to get hwdep running. SND_HWDEP does not get enabled in the kernel.. the reason is sound/core/Kconfig does not have a string with the tristate option. for a hack, i put in "hw dep" that explains why the following happend when i tried to compile btsco Building modules, stage 2. MODPOST *** Warning: "snd_hwdep_new" [/root/kernel-build/btsco-0.41/kernel/snd-bt-sco.ko] undefined! CC /root/kernel-build/btsco-0.41/kernel/snd-bt-sco.mod.o LD [M] /root/kernel-build/btsco-0.41/kernel/snd-bt-sco.ko most of my drivers are modules.. dunnot if it makes sense to load them up as staticly linked drivers???? just musing..i kind of get edgy thinking of installing the kernel again (i lost track of the number of re-compiles i have done so far :D).. restarting again....

http://www.exploits.org/v4l/ i had to recompile the kernel (sigh again) with v4l enabled. Then i compiled spcaview-20051212( http://mxhaard.free.fr/download.html ) since i had a creative webcam live once that was done a reboot later, i ran camorama and xawtv. both worked like a charm... geee.. this is good.. now i got a couple of issues. gnomemeeting does not seem to be able to open /dev/sound/dsp since kde is already controlling it.. mebbe try to get my bluetooth working??

mouse problem: evdev was compiled as a module(CONFIG_INPUT_EVDEV=m in my .config) . add: InputDevice "ALPS Touchpad" #InputDevice "Configured Mouse" in ServerLayout and now either make "CONFIG_INPUT_EVDEV=y" and recompile kernel OR modprobe evdev needs to run before kdm ran, and for this i hacked the /etc/rc5.d/S99kdm and added (lsmodgrep evdev)(modprobe evdev) This works... http://rtr.ca/dell_i9300/ has more details on kubuntu setup. the class is this: To get the Front-Panel media buttons working, it is necessary to map them to the standard XF86-Audio button symbols on X11 startup. A script to do that is here. To have it run automatically in KDE, place it (or a symlink to it) into your ~/.kde/Autostart/ directory. The volume up, down, and mute buttons are handled internally by kmilo (which you might need to install: apt-get install kmilo). To have xmms use the play, pause, prev, next, and stop buttons, I had to download and install the appropriate packag...

Bloddy well miss semagic!! One more of the Inspiron 9300 installation stories.. installed windows xp home edition first. then started with debian.. IMPORTANT: http://fluffi.info/inspiron9300/single/ gives a lot of info.. i'd try and fill the missing links.. I got the sarge dvds (both of them ) and installed a basic install - I just got a shell prompt with *no* audio/video/anyotherthing.. here is the saga so far: hmm.. anyways.. I have my debian useable level at least.. some interesting things: apt-get commands and learnings: http://homepage.mac.com/sao1/fink/commands.html I got the nvidia drivers, the ipw2200 drivers , interestingly these are valid for 2.6 kernel and above. Debian's Sarge installation is with 2.4.27 kernel!! this is painful. so the thing i did was to download 2.6.15-rc6, applied a patch to it, here is how to compile the kernel and create a .deb package - pretty nice to do a dpkg -i and apt-get remove package_name and play around.. libata patch: http://www.kern...
