Nov 05 18:13:44 <ben1066> Hello
Nov 05 18:13:51 <ben1066> Im looking to cross compile kexecboot for arm
Nov 05 18:13:58 <ben1066> Any pointers to getting started?
Nov 05 18:55:24 <Jay7> check http://kexecboot.org/documentation
Nov 05 19:03:19 <ben1066> I did but that's using OE
Nov 05 19:03:24 <ben1066> I figured it must be possible without...
Nov 05 19:13:43 <Jay7> sure
Nov 05 19:13:47 <Jay7> like any other software
Nov 05 19:14:12 <Jay7> but we are using OE as build env
Nov 05 19:14:30 <Jay7> I know kexecboot port exists in openwrt as well
Nov 05 19:15:52 <ben1066> Yeah, this device ships with android
Nov 05 19:15:59 <ben1066> So it doesnt fit into either category
Nov 05 19:33:46 <ben1066> Jay7: what does kexecboot depend on?
Nov 05 21:05:56 <Jay7> some *libc
Nov 05 21:06:00 <Jay7> nothing more
Nov 05 21:20:27 <ben1066> All good, it's now booting, though Im having oddities with the frame buffer
Nov 05 21:20:30 <ben1066> It's missing some initialization that the android recovery does and it doesnt
Nov 05 21:43:45 <ben1066> I have to start the recovery
Nov 05 21:43:47 <ben1066> it seg faults
Nov 05 21:43:54 <ben1066> Then I have to start another kexecboot
Nov 05 21:43:56 <ben1066> end that
Nov 05 21:44:01 <ben1066> well
Nov 05 21:44:04 <ben1066> killall kexecboot
Nov 05 21:44:08 <ben1066> then the original one shows
Nov 05 22:00:29 <ben1066> Well that hack works
Nov 05 22:00:31 <ben1066> Just force it to try and change the pixel mode
Nov 05 22:00:48 <ben1066> Actually results in me getting a 32bpp framebuffer too
Nov 05 22:18:56 <Jay7> ben1066: if you can debug that and provide some patch I'll mainline it
Nov 05 22:18:59 <Jay7> ant__: hi
Nov 05 22:19:22 <ben1066> Jay7: I think I need to select the framebuffer on boot
Nov 05 22:19:25 <ben1066> the nexus 7 has two
Nov 05 22:19:37 <ant__> hello Jay7
Nov 05 22:19:59 <ben1066> So I basically just need a stripped down version of the pixelmode change attempt
Nov 05 22:20:11 <ben1066> shouldnt be too hard
Nov 05 22:20:36 <Jay7> it would be great to have this in kexecboot out of the box
Nov 05 22:23:18 <ant__> Jay7: can you imagine a timeline for the kexecboot work now?
Nov 05 22:24:46 <ben1066> Yeah, I'll work on getting a tidier patch together
Nov 05 22:25:00 <ben1066> kexecboot is easier than I thought to port though
Nov 05 22:25:20 <ant__> have you tested kexec ?
Nov 05 22:25:40 <ben1066> Not yet :P But with tegra 3 it's apparently easy enough to get working
Nov 05 22:25:50 <ben1066> Someone's done it with the transformer prime
Nov 05 22:26:23 <ant__> hm, yes, there was an extra option for hard-rebooting iirc
Nov 05 22:26:28 <ben1066> But yeah I just built it under the linaro arm-linux-gnueabi and it runs just fine
Nov 05 22:26:46 <Jay7> ant__: well, I've signed contract with CEFW and will start this month :)
Nov 05 22:26:50 <ben1066> kexecboot at least
Nov 05 22:26:52 <Jay7> *CEWG
Nov 05 22:27:10 <ben1066> Also need to modify it to use androids stuff for rebooting and such
Nov 05 22:27:20 <ben1066> so I can reboot into recovery, bootloader or into itself for example
Nov 05 22:27:26 <Jay7> ben1066: btw, you can try with text-mode UI
Nov 05 22:27:36 <ben1066> I have no tty avaliable...
Nov 05 22:27:54 <Jay7> hm.. tty detection code is ugly
Nov 05 22:27:55 <ben1066> or is that text mode on a framebuffer?
Nov 05 22:28:04 <Jay7> no, real text mode on console
Nov 05 22:28:14 <ben1066> I dont think I have any easy way to get a console
Nov 05 22:28:17 <ben1066> Ubuntu people did it
Nov 05 22:28:24 <ben1066> not 100% sure how, havent looked into it
Nov 05 22:28:30 <ben1066> gui looks pretty anyway
Nov 05 22:28:36 <ben1066> Only thing it's missing is touch support...
Nov 05 22:29:34 <ant__> iirc couple of OpenMoko devices had it
Nov 05 22:31:18 <ant__> https://github.com/kexecboot/kexecboot/blob/master/evdevs.c#L294
Nov 05 22:31:57 <Jay7> touch support is still in todo list
Nov 05 22:32:06 <Jay7> in long term todo list :)
Nov 05 22:32:12 <ben1066> I might try and implement it similarly to cwm
Nov 05 22:32:16 <ben1066> Since it's also row based
Nov 05 22:32:22 <ben1066> They just split the touch into rows...
Nov 05 22:32:29 <Jay7> any patches are welcome :)
Nov 05 22:32:58 <Jay7> seems touch support is must have this time..
Nov 05 22:33:12 <ben1066> I still have volume buttons
Nov 05 22:33:12 <Jay7> but it's hard w/o calibration..
Nov 05 22:33:15 <ben1066> and a power button
Nov 05 22:33:18 <ben1066> they worked oob
Nov 05 22:33:23 <Jay7> ah, cool
Nov 05 22:34:00 <Jay7> sorry ppl, too late here
Nov 05 22:34:04 * Jay7 -> sleep
Nov 05 22:34:20 <ant__> gn
Nov 05 22:34:22 <Jay7> ant__: I'll be back to kexecboot soon :)
Nov 05 22:34:59 <ant__> we missed the 1.3 release, will be for 1.4
Nov 05 22:35:16 <ant__> (Yocto/oe metadata)
Nov 05 22:40:54 <ben1066> https://dl.dropbox.com/u/11197643/nexus7nearyou.jpg
Nov 05 22:43:50 <ant__> looks like you'd limit X and Y
Nov 05 22:44:45 <ant__>  --enable-fbui-width --enable-fbui-height
Nov 05 22:45:05 <ben1066> To stop it being so tiny?
Nov 05 22:45:08 <ben1066> Might do :)
Nov 05 22:56:21 <ant__> hola bluelightning
Nov 05 22:56:33 <bluelightning> ant__: hola!
Nov 05 22:56:35 <bluelightning> :)
