Wow that took alot of tweaking! finally got updated to kernel 3.4.67+, not sure if I lost or gained anything by doing so tho or shot myself in the foot lol
<brain__>
Running everything from nand and have my sd card installation for doing maint. work or rescue system.
<brain__>
i need food and then its back to work!

hmm. I have a little problem.
<[7]>
UART2 on my olinuxino A20 doesn't want to work.
<[7]>
TX output just stays high all the time no matter what I do
<[7]>
is there an easy way to check if the pin multiplexing worked right, i.e. what's the configured function of a pin at runtime?

gah, the more i try to fix things up properly on the mesa side, the more fbturbo mangles my renders
<hramrach>
that's because fbturbo has broken buffer management to suit the mali blob most likely
<libv>
yes, definitely, but it's quite the mangled mess which does things in the wrong places
<libv>
and i have no idea what the proper usage of dri2 should be, as every pair of graphics drivers seems to have a different idea
<hramrach>
do you have the option to render on framebuffer without X?
<libv>
hramrach: that doesn't help me demoing mesa in any way
<hramrach>
hmm
<libv>
since ssvb seems not really interested in fixing fbturbo, i have to go and hack it to bits...
<libv>
it has no swapbuffers, it has no invalidate...
<hramrach>
if you look at the X server they expect that you allocate whole set of buffers every time
<libv>
and even then, how should i use swapbuffers?
<libv>
i get to allocate front and back, but nobody seems to swap them around
<libv>
it's just wasted cycles talking to X and ump
<libv>
and wasted memory of course
<hramrach>
yes, looks like Chinese design
<hramrach>
seriously, swapbuffers should happen but maybe not with mali/fbturbo because the blob has so disparate idea from X about buffer management that you simply cannot swap buffers when the two are talking together
<libv>
they're all too busy playing political games and reinventing things so they can shout loudly about it, but they never ever do anything solid
<hramrach>
they do dri3 which now includes swapping buffers in the spec :p
<libv>
hramrach: you do know why dri3 is happening, right?
<hramrach>
because dri1/dri2 is a fail, presumably
<libv>
no
<libv>
because then dri3 would've happened in 2009

the mesa/X11 ios really behind so I would not be surprised if they just found that a feature that has been in silicone since like 2007 cannot be implemented with the current dri architecture without bending over backwards
<libv>
hramrach: /msg :)
<libv>
no, has absolutely nothing to do with it
<libv>
this buffer handling stuff needs to be just the same on an ancient voodoo
mkutsevol has joined #linux-sunxi
<libv>
well, at least resize works, because i have put an explicite invalidate in the viewport hook

according to product page it's rgb only?

rgb or 'cpu'

is there an easy way to check if the pin multiplexing worked right, i.e. what's the configured function of a pin at runtime?
<oliv3r>
TheSeven: check the registers?
<TheSeven>
which registers (where is that documented? can't seem to find it on the wiki), and how can I access them?
<libv>
heh, now that i nulled the dri2 structure of fbturbo, things suddenly become more predictable
<TheSeven>
does anyone how how the script parsing thing reacts if a pin appears multiple times, e.g. once as uart_tx and once as spi_mosi?
<TheSeven>
spi_used=0, so I'd expect it to ignore the spi_mosi one and use the uart_tx, but is it that clever?
<TheSeven>
I've tried commenting the unused one, but it didn't seem to have any effect, the uart still doesn't work
<libv>
TheSeven: it search for the section and the string, and retrieves the value
<libv>
the value in this case being the io pin
<libv>
if a section is marked unused, things should not be read any further
<libv>
but as with all things, this is of course not an absolute certainty
<TheSeven>
so the SPI driver initializes the GPIO if it is enabled? or is there something that collects all pin definitions and sets up the GPIOs prior to the drivers initializing?
<libv>
TheSeven: the spi driver should do this
<TheSeven>
I think I read some code somewhere that suggested the latter, but I might well be wrong
<TheSeven>
ok, that shouldn't be causing trouble then
<libv>
TheSeven: i believe there is something in sunxi-tools to show you the status of io pins
<libv>
hrm, pio, not sure whether that really is directly useful
<TheSeven>
I'll have a look
<libv>
ah, yes, it should be useful
<libv>
./pio print ought to do it
<TheSeven>
so now I'll just need to get that running on android

I believe I have gotten the sunxi-mali drivers working but don't really know what the best way to test it is.
<brain__>
the test does spit out the GL Vendor: "ARM" GL Renderer: "Mali-400 MP" GL Version: "OpenGL ES 2.0" tho
<brain__>
glxgears output kind of has me second guessing it.

@brain__ : you are lucky i got problems with mali drivers, impossible to launch an opengles app
<pacopad>
i got this message : LibEGL warning DRI failed to open lima
<pacopad>
no display master tonight ?
<brain__>
I havnt tried any apps other than demos and testing things, checking logfiles reports no errors and everything is loaded properly, i also noticed no more lcd tearing but my main concern is why such a low framerate on glxgears.
<brain__>
what application have you tried to launch pacopad that i can test?
<brain__>
also which kernel version are you on?
<pacopad>
i got ssvb kernel
<pacopad>
for r3p2-01rel1 mali support
FreezingCold has joined #linux-sunxi
<pacopad>
i just run the test app supplied with mali
<brain__>
i am using r3p0 on 3.4.67+ from the olimex olinuxino dev board and it solved alot of my issues. i am rebuilding it now using there .config as a base to see if i can trim down the bloat.
<brain__>
so i guess it works here since the test app does run and display the triangle..kinda a simple test tho?
<froese>
apropos bloat - is there a recent kernel for the A10 without all the android stuff? i looked at the experiment-3.10 tree and it has all this android code (binder, wakelocks, etc) in it.
<brain__>
but my glxgears only shows max 35fps, i think this might be an error on my part...multiple x instances
<pacopad>
i don't think glxgears use opengles
<pacopad>
try gl2mark
<brain__>
yes that is what i figured out but i cant find gl2mark anywere
<pacopad>
you can compile it
<brain__>
i may have to build it from source
<brain__>
ok i have been using irc for this long as still do not know how to direct my message to a particular person lol.

any reason I would run into issues using the 3.4.75 tree with the configuration pulled from the olinixino? running kernel 3.4.67+?
vrga has quit [Quit: Leaving]
<brain_>
this kernel is almost too perfect and id like to keep my builds as similar to this as possible.
<brain_>
mainly just gotta trim bloat, add drivers as modules for my external adapters and remove/add a few features. i usually build modules out of tree by extracting the symbols from the kernel....not working in this case.
