i git pull build kernel with the same .config as before and now while botting i get Waiting for /dev to be fully populated...usb 2-1.4: device descriptor read/64, error -110
<razlept>
pfff

just poweroff board.. remove powersource.. powerit on again.. and now is working fine

anyone about the kernel build process failure?

is still half asleep
<razlept>
Turl: can you help me on that ?
<razlept>
i am trying to build a kernel without sound and video support.. and build is failed
<Turl>
razlept: turn more stuff off until it builds? dunno :)
<razlept>
Turl: basicaly alsa is the problem
<razlept>
Turl: if i have alsa enabled .. it compiles just fine.. if i disable alsa support it not
<libv>
razlept: do you really want Turl to waste time on fixing the build of your highly specific setup?
<razlept>
libv: i just ask if its easy to give a look
<libv>
razlept: just fix the issue yourself
<libv>
razlept: don't ask if it is easy to fix any issue.
<libv>
that's pointless
<libv>
just fix the issue, and then you can afterwards determine whether it was easy or not.
<razlept>
libv: easy for you or Turl
<razlept>
for its not
<razlept>
if it was i would solve it from yesterday till now
<libv>
razlept: so if you spent that long, why do you ask Turl directly whether it is easy to solve it?
<Turl>
razlept: I haven't even seen the build error for what it's worth
<razlept>
also you spend too much time to tell all that
<razlept>
i would learn from that
<libv>
razlept: that's just a mantra used by people who haven't learned how to ask proper questions and haven't learned to fix problems for themselves.
<libv>
razlept: have you heard about this tool called "grep"?
<libv>
Turl just used it.
<libv>
and so did i.
<razlept>
yes i know that tool called it grep
<libv>
razlept: good.

Turl: we really got quite lucky a few years ago with allwinner

but apart from the stability, the network, the driver support, 3d acceleration, extensibility... What have the xfree86/xorg ever done for us?
xinj has joined #linux-sunxi
<libv>
it never promised something radically new in the last two decades.
<juanfont>
i was using debian sid when the xfree86->xorg migration. that was quite radical xD
<Turl>
I still wonder why do some distros have xf86-* package names
<libv>
Turl: because i said so
<libv>
Turl: people wanted to name it xorg-, but every DDX symbol started with xf86
<libv>
xfree86, the organization, was dead, but the xfree86 codebase was very much alive
<libv>
and i was one of the few people actually developing xf86 drivers and further the infrastructure from Q3 2003 till Q2 2006
<libv>
my argument about the ddx symbols was the only thing that really stuck
<libv>
and we ended up with xf86-{video,input}-$name

people like keithp and anholt were working on kdrive (with k of course standing for keith).

and everyone was arguing about killing the xfree86 style DDX in a way not dissimilar of wayland vs x now
<libv>
it's amazing how people have forgotten about such things

akaizen: we run the player that use binaries blobs, to make traces of the registers access, we look at the traces and guess what is the function of the register
