libv, right, I couldn't figure out which clock to add to get it working
<paulk-collins>
libv, also, could you put me in touch with the person I have to give the MIPI tablet (ICOU Fatty I) to at XDC, if you're still interested?

wingrime1: if you have a Cubietruck, then I would appreciate feedback about whether 600MHz DRAM clock speed was working for you or not :)
<wingrime1>
ssvb: sweet
<wingrime1>
Some time ago I have problems with uboot strangnes
viccuad has quit [Read error: Connection reset by peer]
<wingrime1>
I hope it should work now
<wingrime1>
ssvb: thats should work with manline or sunxi 4?
<ssvb>
wingrime1: it works with both of them

looking at the xorg man page, trying to workout how to fix this mouse cursor off set. I have callibated the lcd and tested it with ts_test and that works fine. but the mouse cursor is off set and the offset distance var's depending on where you tap.
<astr>
off set from where you tap
<astr>
tap and drag
<ssvb>
astr: are you using screen rotation?

Maybe i am asking on a wrong channel, but does anybody know where i can get linux/kernel26 which used to stay on anoncvs.handhelds.org before they got shut
<astr>
could what I want be the mouse cursor acceleration options?

<libv>
i have another graphics devroom
<paulk-collins>
libv, that would fit
<wens>
that is a lot of devrooms, 10~15 each day
<libv>
wens: only 4 two day devrooms though :)
<wens>
still i think i'll be running around the place
<wens>
that's not counting the main track stuff
<libv>
the main tracks have been dwindling for years
<libv>
devrooms is where it is at

wingrime: do you have mali module disabled in your kernel config?
<ssvb>
wingrime: just try to run the test program and see what happens
<ssvb>
wingrime: or has it failed already?
<wingrime>
Failed to 'modprobe mali'
<ssvb>
wingrime: no mali kernel module in your system?
<wingrime>
Oh, I should do some more actions ...
<ssvb>
are you running the test program as root?
<wingrime>
ssvb: Will test work with build in mali driver?
<wingrime>
ssvb: I need copy new modules or make mali builin
deasy has quit [Remote host closed the connection]
<ssvb>
hmm, I have not tried this, and afaik mali is only supported as a module
<wingrime>
ssvb: ok
<ssvb>
what is the problem with copying the kernel modules to the device?
<wingrime>
ssvb: remove mmc , connect to pc , mount system , copy , umount , reboot
<ssvb>
yeah, but that's straightforward :)
<ssvb>
and isn't it supposed to be already done in a proper system setup?
<wingrime>
ssvb: yes, I too lazy make nfs boot

ssvb: please make program not fail when modprobe is not success\
<wingrime>
ssvb: I have strange issue with modprobe, but insmod worked fine
konradoo77 has joined #linux-sunxi
<ssvb>
wingrime: what kind of issue? maybe you have not installed the modules properly?
<wingrime>
ssvb: maybe
<wingrime>
ssvb: still not see hung / reboots and test runst normaly
<ssvb>
wingrime: if the test can run fine for half an hour or so, then it is likely that you don't have any dram reliability problems :) but if you can keep it running overnight, that would be perfect
<wingrime>
ssvb: I stoped test and see 2 READ FAILURE
<ssvb>
wingrime: hmm, the READ FAILURE is not good, it means that the test failed
<ssvb>
wingrime: was the background also flashing red?
<wingrime>
ssvb: yep
<wingrime>
ssvb: slowly
<wingrime>
ssvb: I see single bit fail
<ssvb>
wingrime: this all means that the dram config on your device needs some adjustments
<wingrime>
ssvb: yes, one bit always in a same place
<wingrime>
0x54555555 != 0x55555555
<wingrime>
ssvb: Thats means I need aditional phase shift on that signal line?
<ssvb>
wingrime: 600MHz dram clock speed is quite high and we don't expect it to be perfectly stable everywhere
<ssvb>
wingrime: my CT is a bit different from jemk's, yours might be a bit different too
<ssvb>
wingrime: I basically would prefer to run tests at high dram clock speeds to explore the the limits of the hardware and then settle with something more conservative, like 528MHz
philippe_fouquet has quit []
<ssvb>
wingrime: could you try to change 'zq' to 0x10d3900 and run the test again?
<wingrime>
ssvb: seems first bit too have problem
_cajg has joined #linux-sunxi
akaizen has joined #linux-sunxi
<ssvb>
wingrime: if it fails even for one bit, then we know that it is already unreliable
<ssvb>
wingrime: a bit more detailed data is presented in the colored tables in the wiki, but getting these results needs a bit more efforts to setup and run
cajg_ has quit [Ping timeout: 272 seconds]
<wingrime>
ssvb: indeed, but how frequency it can make bug?
<ssvb>
wingrime: nobody knows for sure, but even failing let's say once per week would be rather bad
<ssvb>
wingrime: if the test finds problems, it is already a bad news
<ssvb>
wingrime: if the test can't find any problems, we can't be totally sure either
<wingrime>
ssvb: change zq possible only with uboot rebuild ?
<ssvb>
wingrime: yes, u-boot needs to be recompiled
<wingrime>
ssvb: I hoped there better way, like spl use failsave , than uboot/ kernel reinstall new parameters
<ssvb>
wingrime: sorry about this, we should definitely make this stuff easier to use
<wingrime>
ssvb: we still not have autodetection or total universal config?
<ssvb>
wingrime: we do have a universal dram config, but it only works reliable for low clock speeds
<ssvb>
wingrime: anyway, if we can find the dram config tweaks, which allow all Cubietruck boards pass the lima-memtester test at ~600MHz (or ~576MHz), then stepping down to 528MHz is likely going to be safe
<wingrime>
ssvb: thats should be better done by tom on development stage :p
<wingrime>
ssvb: not sure we here have enought ct to have some reliable statistics , not even talking about revisions
<ssvb>
wingrime: yes, this work should be preferably done by board manufacturers (CubieTech, OLIMEX, ...), but we need to provide them with tools and instructions :)
arend has quit [Remote host closed the connection]
<ssvb>
wingrime: we, as a community, can probably do it for a single board (Cubietruck?) as an example, but this needs a bit of coordination from maybe ~5 board owners to get relevant statistics
<wingrime>
ssvb: + .zq = 0x10d3900,
<wingrime>
ssvb: not helped
<ssvb>
wingrime: thanks for trying
<wingrime>
ssvb: and now stange , memtester write many messages about reducing memblock?
<ssvb>
wingrime: reducing memblock errors probably means that the block is too large or you don't run it as root
<ssvb>
wingrime: that's a memory buffer allocation problem (no free space left or no permissions)
<ssvb>
wingrime: "not helped" means that you get memory corruption errors reported again?
<wingrime>
ssvb: oh , newer thinked about that root have special privileges about memory allocatation
<wingrime>
ssvb: looks like error presed, but not so freqently
<wingrime>
ssvb: *present
<wingrime>
ssvb: interesting ... with root , cube not redish even one minute passed...
syeekick has joined #linux-sunxi
<ssvb>
wingrime: to improve reliability, you can step down to 576MHz or tweak tpr3 (change it to 0?)
