My company is willing to invest money in development around Allwinner chips and Linux support. Are there any interested parties for cooperation?

david00: free-electrons people, in particular mripard may be interested

Turl: thanks. I'm still new here so I don't get who is who yet. I will contact them
<Turl>
david00: if you have any specific proposals, you could also send an email to the linux-sunxi list, see http://linux-sunxi.org/Mailing_list
<david00>
Turl: yes, I will do that. In the meantime, anyone who is interested can email to info@bylapis.com

So I'm reading http://linux-sunxi.org/Mainlining_Effort , the MMC driver is under 'Left To Be Done' - does that mean that SD does not work with the mainline kernel yet?
<lunra>
Sorry to ask if it's a bad question

mnemoc: A20 and A31 are interesting for us as they have quite impressive power and abilities like hardware video decoding
<mnemoc>
due to the ugly PVR inside the A31 the community hasn't put much attention on it, but A20 is pretty decently supported
<mnemoc>
also the A31 includes a weird 5th openrisc core inside :\
<hno>
not sure it's weird.
<hno>
much better power efficiency than having one of the ARM cores doing deep suspend monitoring like done on the other chips.
<mnemoc>
true
<hno>
plus can keep running doing other stuff in the backgrond.
<mnemoc>
have you get own-code running in the ar100?
<mnemoc>
btw, thinking in a single-u-boot-bin, using soc-detection and a separated dd'ed board-specific data.... instead of using an dumped struct, or something needing a fat parser, what about just using a "fex" block?
<david00>
what is still TODO for making A20 decent chip for building Linux network media player?
<mnemoc>
or we actually CAN read a .dtb early enough?
<mnemoc>
david00: cedarx, the vpu, has already reverse engineered free hw accelerated mpeg2 and h264 decoders
<mnemoc>
david00: but there are armhf gpl-violating blobs too...

mnemoc: I see now. Would it be possible to render decoded video onto OpenGL texture, with mem copying, a.k.a. "slow path" rendering. I not sure if chip has enought power for that...

david00: libv is the right person to answer that
<mnemoc>
he is the one reverse engineering mali (the GPU)
<mnemoc>
and I bet he would be glad to be sponsored to finish the lima/mesa integration ;-)
<n01>
mnemoc: btw, we will see each other @ fosdem?
<david00>
mnemoc: I hope he will see this :) btw, sorry if I ask stupid questions, I'm more manager than hacker. But sometimes its required to merge those two to support community

torindel has quit [Ping timeout: 245 seconds]
<mnemoc>
david00: don't worry =)
<hno>
mnemoc, I know it doesn't scale. Partly why I want to get rid of them all... and size diff is amasing. would expect 3 different only (non-SPL, SPL without AXP, SPL with AXP)

oliv3r: ping
<mnemoc>
david00: there are basically two proprietary blobs in the sunxi world, VPU and GPU. and two possible GPUs. PVR on the A31, hated but usable using libhybris from linux. and mali-400 on all other known SoCs, been REed my libv. but we have linux blobs too
<wingrime>
hnoL ping
<wingrime>
hno: ping
<mnemoc>
hno: soc-detect + a dd'ed fex block might scale pretty well :) ... and dynamic enough to not be bound to a blessed struct
<wingrime>
david00: VPU blob not absolte nowdays
<wingrime>
david00: we have REd implemet for h264 and mpeg12
<mnemoc>
david00: the VPU in all is called cedar and it's been REed by jemk, wingrime and others. decoding mpeg2 and h264 with 100% free software
<mnemoc>
then I can only think in a corrupted uImage...

mnemoc, no space for a fex block, unless you can fit parser & data in 2KB.
<wingrime>
mnemoc: that looks something wrong with host system
deasy has quit [Quit: Nom d'un quark, c'est Edmonton !]

mnemoc, new u-boot do not read from different address, but SPL expects u-boot to be an uImage, not a raw binary. Unintentional upstream change for the beter.

I have problem with setting up X server. I try to use fbdev and fbturbo but both doesn't change anything on LCD. It is always lit up black screen
