libv: the exynos people were seeing ~100ms runs when mixing framebuffer and ion or framebuffer and ump allocations, don't remember now the specifics :P

If I'm trying to run the a10 in qemu, what -cpu ? should I use? Cortex-A8?
avernos has joined #arm-netbook

Is this the right place to get help with making rootfs on SDcard for working with a10 devices? Or is there a seperate channel for that purpose? mnemoc?
<Turl>
ManoftheSea: yeah
<Turl>
ManoftheSea: you won't be able to run the kernel on qemu though
<Turl>
ManoftheSea: I suggest you use a chroot + binfmt with qemu-static-arm
<ManoftheSea>
thanks turl. I will attempt to figure out what you said, but it looks useful.
<ManoftheSea>
(what's binfmt?)

has found info on the internet. Will have more questions tomorrow
<ManoftheSea>
ok, I think I got debootstrap --second-stage running in a qemu chroot.
<ManoftheSea>
Tomorrow, I find out if my uboot and kernel match correctly. MK802 mk. II here.
<Turl>
ManoftheSea: I was suggesting debootstrap with --foreign, then installing qemu-user-static on your pc (sets up binfmt by itself even), then copy /usr/bin/qemu-arm-static yourchroot/usr/bin
<Turl>
then chroot to the arm install and run the second step (debootstrap --second-stage or so)
<ManoftheSea>
Yep. Thanks, turl, I found all that just from your mention of the programs. I have completed the second stage, and an finalizing the debootstrap now.
<Turl>
I think there's even a guide of it on the wiki
<libv>
Turl: could be that not all buffers are mapped in the range where the display engine might directly accept the
<libv>
them
<libv>
then you need to revert to a copy

Turl, MALI apparently have a static region it's allowed to DMA to, other regions apparently gets copied by the CPU.. Saw some post in developer.arm.com forum about performance issues and ARM pointed to possible kernel/userspace mismatch in allowed direct access memory region.

Quarx: need to test hwcomposer, it wasn't loading due to bad version
<Turl>
Quarx: we are affected by the same mali issues as the exynos people
<Turl>
maybe need to adjust mountpoints, haven't checked what's the new ones on 4.2
<RaYmAn>
mountspoints need fixing, otherwise android crashes
<Quarx>
on razr we didn't change anything
<Quarx>
after 4.1
<Quarx>
but on defy i still can't get work sd-ext
<RaYmAn>
you didn't add that silly patch that just hacks around having to change mountpoints?
<Turl>
RaYmAn: well it didn't crash for me o.O
<RaYmAn>
a lot of people decided to fix the symptom rather than fix the cause
<Turl>
unless CM merged that patch
<RaYmAn>
they might have I guess
<Turl>
RaYmAn: what's the new mountpoints btw?
<Turl>
we have internal+external vfats
<Quarx>
on defy i can browse sdcard only via adb, android didn't see files and sd%)
<Quarx>
but it's mounted
<RaYmAn>
Turl: well, not mount points per say I guess, but the mount stuff in init.<device>.rc: http://pastebin.com/0gkkvSnA
<Turl>
RaYmAn: well I've been using /storage/sdcardX since 4.1
<Turl>
I didn't add any of the other emulated crap though
<Turl>
where do you mount stuff with vold?
<RaYmAn>
Turl: of course, that was required in 4.1. This is required in 4.2
<Turl>
/storage/sdcard0 is a symlink, where do you mount it then? :p
<RaYmAn>
I mount internal eMMC data on /data as always
<Turl>
yeah but that's not internal vfat
<Turl>
:)
<RaYmAn>
yeah, there's not really any place for internal vfat anymore :P
<Quarx>
RaYmAn: any changes for sd-ext?
<Quarx>
defy doesn't have internal vfat
<jinzo>
Motorola Defy is using an A10?
<Turl>
no, it has an OMAP3 CPU
<RaYmAn>
this channel might have become mostly a10, but it is still a generic channel ;)
<jinzo>
ah ok, sorry - I loked at your android github repo and had to ask
<jinzo>
RaYmAn, I actually tought because of "Repo entries for CM7/9/10 Nightly builds, Motorola Defy,Defy+,Bravo. Ainol Novo7 Aurora(A10) "
<Turl>
cpu wise it should be roughly equivalent on performance
<Turl>
both are cortex a8 and the clocks are fairly similar
<jinzo>
but it's very nice to see someone is working on a A10 CM (and I quite like ainol as a company)
hipboi has joined #arm-netbook
<Quarx>
i wonder why they no release official 4.1
<jinzo>
(and they're quite interesting, every new product "line" they out has a new processor - and everything in there has the same on - A10 for previous, AML8726-M6 for current ad ATM7029)
<jinzo>
probably because they wish to make money off the new ones - they're pumping new products at high pace and like I said - newer the same platform
<jinzo>
I really don't know why underdogs like them don't go with CM all the way
<Quarx>
but almost all sources available for 4.1 (from allwinner)

hipboi: regarding your last email, why A31 and not A20? :)
<hipboi>
A31 first
<hipboi>
A20 later
<hipboi>
just like A10 and then A13
<Turl>
so allwinner doesn't have A20 chips yet?
<hipboi>
sorry, i don't know
<hipboi>
i only know the time order
<Turl>
A20 is pin compatible with A10 and has Mali GPU
<hipboi>
yes
<Turl>
personally I think it would be a better fit (lima hint hint :) ) and faster to make for you guys
<Turl>
and I think it has sata so you don't need to lose features
<hipboi>
yes
<hipboi>
plus sata and 1000M ethernet

Good morning guys

I'm messing with a MK802 mkII, and I think I got my root fs all set up and qemu-debootstrapped. I see some reference to "issue 46", but the page doesn't load.
<ManoftheSea>
When I try to boot, no output.
<Turl>
did you flash uboot to your card and set up kernel properly?
<Turl>
also, what output are you expecting?
<ManoftheSea>
I have an 8 GB SDcard, with SPL at 8k and uBoot at 32k, then a 32MB partition formatted vfat with uImage and script.bin, then a root partition.
<ManoftheSea>
Turl: I have the MK802v2 hooked up to HDMI. I thought I'd get a console. no?
hipboi has left #arm-netbook ["Leaving"]
<Turl>
ManoftheSea: did you enable fbcon? your best bet is to use uart though
<Turl>
there's a lot of stuff that could go wrong
<Turl>
and you cannot catch it with hdmi
<Turl>
you probably need an uboot environment/uEnv.txt to add rootwait btw
<ManoftheSea>
hmm... I like your suggestions, but I have no idea what you're actually saying. uart requires taking the case off the stick and connecting to JTAG?
<Turl>
s/to JTAG/to an UART to USB adapter/

so, not serial.

Where does "mkimage" come from?

some uboot tools package iirc
rz2k has joined #arm-netbook

so, "first-steps" doesn't say what to do with boot.scr. Does it go on the boot partition?
<Turl>
yes, together with script.bin and uImage
<ManoftheSea>
and you mentioned using fbcon. That goes in /etc/modules?
<Turl>
possibly, don't know for sure
* Turl
prefers =y instead of =m if he is going to use the feature, =n otherwise
<ManoftheSea>
ok, I'll check the .config
<ManoftheSea>
I don't have the module, it seems
<ManoftheSea>
says no. Guess I need a toolchain and a recompile. Whee! Thanks again, Turl

ManoftheSea, for small changes to the boot procedure uEnv.txt is simpler.
<techn_>
hno: finally I found trigger for that boot problem :/

If I comment out sunxi_gpio_set_cfgpin(SUNXI_GPB(22), SUN4I_GPB22_UART0_TX); \ sunxi_gpio_set_cfgpin(SUNXI_GPB(23), SUN4I_GPB23_UART0_RX); , device boots
<techn_>
I'm wondering why it's so.. and why lichee u-boot doesn't have those lines :/
<ManoftheSea>
hno, it looks like I shouldn't be expecting HDMI out, right? So, I need to get the usb->uart before I can do more.
