01:30.27dullardsays hello from his htc universal
01:31.48dullardWould anyone in here know anything about the inner workings of titchy mobile?
01:33.52dullard...I think I lost my xserver in an apt-get upgrade and I have no idea where to find it again
01:35.45rainabbaYou talking xserver on an HTC phone? (new here)
01:36.46tcccpapropos
01:37.03tcccpI could try and see if the iPaq can have X easily

01:44.04dullard_<-- running debian on htc universal
01:44.55tcccpDebian on HP iPaq hw6915
01:47.30dullard_tcccp: do you know whether there is a generic name for the xservers running on debian handhelds? I want to find out if the server is still on my machine... xdm is doing nothing
01:48.11tcccperm..hu?
01:48.18tcccpThe package name should be xserver-xorg
01:51.38dullarddo you know what it would be called at the command line to do a quick check that it exists?
01:55.05tcccpuuh
01:56.07tcccpdpkg -s?
01:58.59dullardI mean hmmm... something like startx but the name of the actual xserver
01:59.44tcccpls -l /usr/bin/X
02:00.13dullardis that generally a symlink?
02:00.19tcccpaye
02:00.34dullardaah my symlink is missing
02:01.14dullardwhat does yours link to? that may or may not give me a clue
02:01.40tcccpXorg for example - same dir
02:03.37dullardwierd, I really think mine's gone missing. I don't know where.
02:06.17tcccpAnd I need to fire up my "development virtual machine" to have a new kernel

20:21.25martin__dcordes: I think I may have found another smd channel
20:22.01martin__look in your smem5 dump around 8220
20:22.29martin__looks like just a data channel of some kind
20:22.46jastadoes anyone have any tips on how i might go about introducing USB support to the HTC Vogue (MSM7500, with I believe a driver present in the android-msm kernel tree)
20:22.50jasta?
20:23.25martin__jasta: have you talked to dzo about it?
20:24.10jastayeah, but he is very busy and i feel bad bugging him about all my minutia.  i'm unfamiliar with haret and kernel dev in general, and am just looking for some direction to get started with my exploration.
20:24.47martin__hmm
20:25.17*** join/#htc-linux CVirus (n=GoD@82.201.174.159)
20:25.23jastafor example, how can i access printk output?
20:25.36martin__normally by seeing it on the framebuffer
20:25.50martin__if it's working :)
20:26.13jastabut it appears only briefly when booting Android
20:26.23martin__don't boot android, then. :)
20:26.40jastawell, that would be too obvious of course.
20:26.46jastahehe
20:26.52martin__i use a simple image that just boots to a shell
20:26.59martin__on kaiser
20:27.06martin__which i got off dcordes
20:27.08jastai am embarrassed i didn't think to do that :)
20:28.12martin__the one i'm using is from here: http://linuxtogo.org/~lgorris/images/
20:28.19jastacan i have what you have prepared already?  would be easier than creating my own simple initrd
20:28.23jastaahh, thanks.
20:28.38martin__i don't know for sure if that will work on the vogue but i think it should do.
20:28.57jastadzo wrote a soft keyboard driver as well, which i for some reason assumed was part of android and not the kernel image.
20:29.00jastaso that should work all the same.
20:29.46martin__oh, right, vogue doesn't have a keyboard
20:30.11*** join/#htc-linux Marex (n=marex@vasut.kolej.mff.cuni.cz)
20:30.27martin__well, i dunno anything about that soft keyboard stuff
20:30.30jastayes, but stil with the soft keyboard i could explore, even if very slowly.
20:30.51jastadzo wrote it.  it basically is just a hack on the framebuffer and touchscreen drivers.
20:31.11martin__nice, so it draws the keyboard on the framebuffer directly?
20:31.17jastaultimately i want USB up so i can access android's shell remotely and also the android log.
20:31.28jastayeah, essentially as an overlay.
20:31.58jastai've pined through the source code quite a bit, there just seems to be pieces that are quite magical to me, given that i have no experience developing on this sort of project.
20:32.45martin__in some ways you might be best off finding a device linux already works well on
20:32.58martin__and using that to play around with
20:33.03martin__to get an idea of how things work
20:33.34martin__e.g. putting debug messages in to help follow what happens as it starts up
20:33.45jastawell, i'm ultimately trying to work with Android and so only devices which have very similar processors will work
20:33.51jastaoh, i see what you mean
20:33.53martin__or deliberately breaking things and seeing what happens
20:34.14martin__there's good books on the kernel too that might help
20:34.16jastawhat device would you recommend for that?
20:35.09martin__one of the ipaqs maybe?
20:35.27martin__or one of the older htc devices?
20:35.47martin__but perhaps the best start is to read this: http://lwn.net/Kernel/LDD3/
20:37.28jastathanks, i will look through it.

21:10.33martin__6a2a0 could be one too
21:14.03dcordes_hi
21:15.43dcordes_yes there are plenty. It should be 7 iirc
21:17.29dcordes_martin__: 'brute forced' the at tx yet?
21:17.50martin__dcordes: i don't get where the gps guess comes from, unless that address fills with gps stuff when the gps is used
21:18.23dcordes_martin__: different dump
21:18.27martin__k
21:18.34dcordes_the one I sent has no gps activity
21:18.40dcordes_let me see where I got it
21:20.41*** join/#htc-linux pikapika_ (n=pikapika@mar75-8-88-164-227-147.fbx.proxad.net)
21:26.06dcordes_martin__: sent. so did you do that brute force code yet?
21:26.41martin__no, i'm looking at the dumps to figure out how best to do it
21:26.52martin__i'm not sure it'll really help with the at send stuff
21:26.59martin__the location of that seems pretty clear
21:27.19dcordes_you think correct how it is i the current state?
21:27.35martin__i think it's more likely we're missing something about how to get the arm9 to read it
21:27.57martin__i could try the head/tail swap i suppose
21:28.09martin__i thought that was likely not right because it isn't needed on the vogue
21:28.27martin__but then looking at the vogue addresses suggests the smem is a very different setup there
21:28.47dcordes_martin__: if there is nothing to to notify the arm9 about reading in the vogue code, why would we do need it?
21:29.19martin__the msm7500 might have made it automatic
21:29.30martin__the smem setup is clearly different
21:29.53dcordes_I see
21:29.54martin__e.g. with the vogue all the heads and tails are together in one place
21:30.29dcordes_so maybe we really need to throw an irq?
21:33.31martin__possibly
21:33.41martin__or we might need to write somewhere else
21:34.09martin__there's a couple of stray bits set just before the heads and tails of the smd buffers
21:34.18martin__they might be important
21:35.57martin__but no idea what they're for or what they mean
21:36.29dcordes_stray bits? can you give me a line number?
21:36.42martin__well, look at 000041f0
21:36.51martin__000041f0  02 00 00 00 00 01 00 00  00 00 00 00 df 1e 00 00  |................|
21:36.55martin__00004200  df 1e 00 00 00 00 00 00  40 53 59 53 54 45 4d 54  |........@SYSTEMT|
21:37.25martin__you've got the 02 ... 01 ... then the head and tail, then the block
21:37.45martin__now, search for 02 00 00 00
21:38.02martin__it comes up again at 8220
21:38.15martin__which also has what look like a head and tail
21:38.39martin__but now there's more bits set: 02 00 00 00 01 01 01 00
21:39.04dcordes_maybe they identify the fifo?
21:39.20martin__ah
21:39.31martin__they're always 32-bit aligned
21:39.49martin__so search for "  02 00 00 00" including the two spaces at the front
21:40.02martin__you'll see all the smd locations
21:40.23martin__and they've all either got:
21:40.29martin__02 00 00 00 00 01 00 00
21:40.42martin__02 00 00 00 00 01 00 00
21:40.51martin__02 00 00 00 01 01 01 00
21:40.53martin__sorry
21:40.56martin__just the last two
21:45.58dcordes_martin__: do you think we might need to write those bits with the send buffers?
21:46.09martin__possibly
21:47.03martin__i'll try printing out the state of those bits for the working smd
21:47.20dcordes_I have no dump from the vogue but I believe somehow it looks similar there
21:47.29martin__and maybe just wildly toggling them on the non-working one :)
21:48.15martin__anyway
21:48.18martin__got to go now
21:48.29dcordes_ok cya
