<fralle_> is it possible to skip all fel modes keys (except FEL button) from fex file?
<fralle_> boot 1 finds a key and enters fel mode... where does it look for the keys...

<oliv3r> fralle_: nope, i think it's hardwired
<oliv3r> fralle_: i think boot1 doesn't parse script.bin
<fralle_> ok
<fralle_> but when u create a live image it does something with the fex fil on the boot0&1
<fralle_> do u know which are the keys?
<fralle_> "keys"
<fralle_> for recovery...
<fralle_> which pins on the a10... (Turl spoke about lradc yesterday but are there other gpios interfaces where it looks?)
<speakman> Regaring CPU governors; will there be any problems running with "performance" at all time? I have no battery or anything. And since the CPU usage is mostly at 0% I guess the CPU will still be sleeping most of the time anyway?
<rm> it won't be sleeping
<rm> but it's no problem
<speakman> Won't be sleeping?

<mnemoc> damn secure boot! if I boot my laptop from a usb stick the sata port is disabled!
<mnemoc> *rage*
<speakman> mnemoc: it's for protecting you, remember?
<mnemoc> speakman: :)
<speakman> Btw, are there any "rule of thumbs" for optimizing CPU performance on sunxi? I need every single clock cycle available on my A20 :/
<rm> speakman, obviously it won't drop to lower MHz with the "performance" governor
<rm> but the difference in power consumption was measured to be not too significant
<speakman> rm: comparing to..?
<rm> between e.g. idle at 408 MHz and idle at 1000 Mhz

<speakman> Oh, I see. I just adjusted lowest CPU freq from 60MHz (default) to 408MHz in the kernel. I guess that's a good start?
<speakman> I just found this one. A good start: http://www.cubieforums.com/index.php?topic=24.0
<mnemoc> the cpufreq page was one of the first to be added to the linux-sunxi wiki long before lawrence created that forum
<speakman> mnemoc: oh, havn't seen that one. Gah.

<speakman> I've been cleaning up the kernel config (a lot) and now I get "Warning: unable to open an initial console". The console is (as it often is) on ttyS0. But I don't remember disabling sunxi serial. Hm.
<speakman> Are there any kernel debug options to enable to facilitate the search for the error source?

<alexvf> libv: you said you have used the sprite controller
<alexvf> libv: have you been able to draw different pixels in a sprite column?

<libv> ?

<alexvf> libv: i fill the memory with random bytes and all i see is random vertical lines

<alexvf> libv: maybe i don't understand how it works
<libv> alexvf: try filling it with something real
<alexvf> libv: do you have some code that i could look at?
<libv> alexvf: gimp will export to C
<libv> not yet
<alexvf> i made the following ioctls to show a sprite: DISP_CMD_SPRITE_OPEN, DISP_CMD_SPRITE_SET_FORMAT, DISP_CMD_SPRITE_BLOCK_REQUEST, DISP_CMD_SPRITE_BLOCK_SET_TOP, DISP_CMD_SPRITE_BLOCK_OPEN

<bfree> forgive my stupidity but just checking, with respect to the mainlining page is SPI==sd-card (/dev/mmcblk)?
<wens> bfree: no
<wens> bfree: mmc is a separate driver
<libv> alexvf: i am not using the disp ioctls.
<libv> alexvf: i am using a fresh bit of code which talks to the registers.
fralle_ has quit [Remote host closed the connection]
<alexvf> libv: ok, i think i'm not at that level at all :)
sehraf has joined #linux-sunxi
<bfree> wens: thanks. I'm probably being blind then ... where is it mentioned at linux-sunxi.org/Mainlining_Effort ?
<alexvf> libv: if sprites are a such rare functionality, sprites ioctls could even be buggy and that's why it's not working
<Turl> ccaione: ?
<libv> alexvf: quite likely, yes
<ccaione> Turl: np, you are op ;)
<Turl> bfree: look for mmc
<alexvf> libv: ok, thanks
<Turl> ccaione: not any longer :p
<ccaione> hahah
<bfree> Turl: mmc is not on that page anywhere?
<Turl> bfree: ah
<Turl> bfree: it's listed a SDIO
<Turl> leviathanch: ^
<bfree> Turl: ah ok, thanks, I was thinking it wasn't SDIO (as that's usually for "other" stuff running in sd)
rz2k has quit []
<leviathanch> Turl: hi
<leviathanch> has the patchset finally been merged or what? ^_^
<Turl> leviathanch: not yet afaik
<Turl> leviathanch: I'm just pointing bfree to the right person :)
<leviathanch> Turl: ok :-)
<leviathanch> Turl: what's the matter? does he wanna use SDIO functionality?
<leviathanch> that hasn't been tested yet
<leviathanch> since I didn't have a gadget with SDIO device in
<leviathanch> if you wanna donate a gadget with allwinner chipset and sdio device in it
<leviathanch> i can do development for it ;-)
<Turl> I dunno what bfree needed :p
<Turl> leviathanch: iirc cubietruck has a sdio wifi thingy that worked
<bfree> I was only trying to figure out what I might do for a ~mainline kernel to test that half of my "sunxi-boot" stuff properly. not looking for sdio
<Turl> leviathanch: talk to wens
<Turl> (or hans)

<wens> currently it doesn't work, not sure what the problem is
<wens> but it worked with the first version of the mmc patches
<wens> ccaione: looked at cubieboard / cubietruck designs, they don't use all of AXP209's outputs
<wens> leviathanch: the latest version (see hans' sunxi-devel branch) can enumerate the SDIO chip, but hangs somewhere during brcmfmac probe
<leviathanch> wens: ouch
<leviathanch> wens: hans did some fixing against IRQ bombs
<leviathanch> wens: maybe that broke the correct initialization of your device
<leviathanch> ...
<wens> IRQ bombs?
<leviathanch> yes
<leviathanch> wait a sec
<Turl> wens: bombs that request your permission before blowing up
* Turl hides
<leviathanch> lol
<leviathanch> I better don't talk about explosives here in IRC, otherwise I might get onto one or two additional agency watch lists >_>
<leviathanch> but anyway
<leviathanch> wens: these two patches might be the root of your problem
<leviathanch> otherwise I only changed minor stylistic details
<leviathanch> changing the defines from camel case into uppercase was the biggest change
<leviathanch> and this change didn't do any functional changes
<wens> well there were changes to brcmfmac during the previous window, so... I have no clue what happened :(
<leviathanch> wens: I will track this issue as soon as I'm back from the project again
<leviathanch> will be late at night I guess
<wens> I'm thinking it might be the wifi module isn't powered on when the probe occurs, but it's a wild guess
<wens> the thing is the worker thread just hangs there, load average at 1.0, and it sometimes blocks reboots :(
<wens> and mmc worker thread is shared, so it also blocks card detection on mmc0
<leviathanch> ok
<leviathanch> I will takkle this
<leviathanch> as soon as I've got some time between two projects
<leviathanch> ... actually
<leviathanch> I could work on it during my train trip later on
<leviathanch> :-)
<leviathanch> uhm
<leviathanch> but now I'm away
<leviathanch> for work
<leviathanch> I'll have a look
<leviathanch> promise
<leviathanch> :-)

<leviathanch2> try the last patch
<leviathanch2> it should fix your issue I assume
<leviathanch2> since hans has moved the irq and clock enable routines
<leviathanch2> it may very well be possible that the clocks aren't on at all
<leviathanch2> at the time when sdio irqs are enabled
<leviathanch2> which would lead to the timeout you describe
