2012-06-16 12:59 <viric> lindi-: is that mips?
2012-06-16 13:00 <lindi-> no, armel
2012-06-16 13:01 <lindi-> but you probably have same bugs with unaligned accesses
2012-06-16 13:01 GNUtoo-desktop has joined #qi-hardware
2012-06-16 13:01 <viric> well, I was using webkit 1.4.0. Maybe a newer webkit works better. And the troubles were in the unaligned-access-emulation of mips.
2012-06-16 13:02 <viric> specifically.
2012-06-16 13:06 <viric> lindi-: and it's related to FPU, that the openmoko maybe does not have

2012-06-16 13:31 <mth> unaligned access emulation is a horrible thing anyway; it's much better to fix the program doing the access
2012-06-16 13:32 <viric> of course
2012-06-16 13:32 <viric> but it becomes a matter of performance, then. Not a matter of "the program does not run"
2012-06-16 13:33 <viric> and with an 'echo' to a debugfs file, you can make all programs sigbus, if you want, on unaligned access. It becomes up to the kernel user.

2012-06-16 13:41 compcube has quit [Quit: Leaving]
2012-06-16 13:43 <mth> yeah, but I think that trying to make broken programs run is not a good idea, because it decreases the chance of them getting fixed
2012-06-16 13:44 <mth> also, the resulting system is more complex, like you found out when there was a bug in the unaligned access emulation
2012-06-16 13:45 <viric> then maybe you'd like the sigbus behaviour to be the default, and the emulation not default
2012-06-16 13:45 <viric> but it should not be about not having that code in the kernel at all
2012-06-16 13:46 <viric> Imagine a super-complex package has unaligned accesses, and the producers of the package do not give a penny for your platform.
2012-06-16 13:46 <viric> (hypothetical case :)
2012-06-16 13:47 <mth> the emulation can be useful even if only for logging where in the program the unaligned accesses come from
2012-06-16 13:47 <mth> but indeed I wouldn't want it enabled by default
2012-06-16 13:48 <mth> same for floating point emulation: I'd rather have the program crash so that I know that softfloat support failed

2012-06-16 17:38 <larsc> Ayla: that's an interresting way to implement a msleep() ;)
2012-06-16 17:40 <Ayla> isn't it? :)
2012-06-16 17:40 <Ayla> I actually wasn't aware of msleep()...
2012-06-16 17:40 <Ayla> I know mdelay, not msleep
2012-06-16 17:41 <larsc> msleep sort of does what you just implemented
2012-06-16 17:42 <Ayla> ok, I'll edit it then
2012-06-16 18:01 <qi-bot> [commit] Paul Cercueil: ASoC: JZ4740: Use msleep() to wait before enabling the DAC. (jz-3.4) http://qi-hw.com/p/qi-kernel/5d267d6
2012-06-16 18:01 <Ayla> mth: that means we could replace all mdelay() by msleep() on the SLCD panels code
2012-06-16 18:02 <Ayla> so that the other threads can continue when the panel is initializing
2012-06-16 18:03 <Ayla> that was a request reported on the kernel bug tracker
2012-06-16 18:03 <mth> yes, sounds like a good idea
2012-06-16 18:08 <Ayla> at which point is it better to use msleep over mdelay, or the other way around?
2012-06-16 18:09 <Ayla> on some parts of the code, I waits only 10ms
2012-06-16 18:09 <Ayla> s/I/it
2012-06-16 18:09 <qi-bot> Ayla meant: "on some parts of the code, it waits only 10ms"
2012-06-16 18:09 <Ayla> msleep() probably introduces a higher delay
2012-06-16 18:10 <wpwrak> "only" 10 ms :-)
2012-06-16 18:10 <Ayla> but I'm not sure it's important whether it waits longer than 10ms or not
2012-06-16 18:10 <wpwrak> that's a pretty nasty delay, if you spend that time spinning
2012-06-16 18:11 <Ayla> well, the panel enable function spins for like one second total
2012-06-16 18:12 <Ayla> 510ms for the ili9325 panel
2012-06-16 18:12 <wpwrak> mdelay ? urgh
2012-06-16 18:12 <Ayla> yes :)
2012-06-16 18:13 <Ayla> IIRC we use HZ=250 on dingoo, so a msleep() will last 4ms minimum
2012-06-16 18:13 <Ayla> and msleep(10) will sleep 12 milliseconds
2012-06-16 18:14 <wpwrak> just hope you don't have anything remotely real-time-ish on that machine :)
2012-06-16 18:15 <Ayla> we do, sort of
2012-06-16 18:15 <Ayla> the sound output
2012-06-16 18:17 <larsc> which is taken care of by dma
2012-06-16 18:18 <mth> only for the span of the current period though
2012-06-16 18:18 <mth> the sound output is broken when the SLCD init happens
2012-06-16 18:19 <mth> when unblanking, for example
2012-06-16 18:19 <mth> Ayla: I think that even 1 ms is a lot of time for this CPU
2012-06-16 18:19 <Ayla> larsc: yes, but the app that produces sound is blocked
2012-06-16 18:20 <mth> and afaik the 4 ms time slices matter when there are multiple active threads, but it doesn't mean a single active thread has to wait for the next time slice
2012-06-16 18:20 <Ayla> ok
2012-06-16 18:20 <Ayla> I replaced all mdelays by msleeps, and it works good
2012-06-16 18:20 <Ayla> now the sound doesn't stop when I un-blank the screen on GMU
2012-06-16 18:21 <mth> zLoud will be so happy
2012-06-16 18:22 <Ayla> heheh
