09:35 <karlp> xr829? what's that behind the scenes? is that going to be functional wifi+bt or xr819 style?

09:40 <karlp> oh dear, looks like xr819+bt. so... abort....

10:51 <neller123> Can anybody help me please with adding the new resolution to Android 7.0 for Orange PI 3? This image uses sunxi-3.10.65. I want to change one of default resolution to my. (For example: 720p to 1280x800). In which files in the kernel and in which files in the AOSP should I make changes? Driver page is

10:51 <neller123> https://github.com/orangepi-xunlong/OrangePiH6_kernel/tree/master/drivers/video/sunxi/disp2/hdmi2. Thanks a lot for advaces!

11:15 <karlp> neller123: this is _generally_ a channel for people working with mainline kernsl, not legacy vendor kernels. you might get help, but don't hold your breath...

11:59 <montjoie> neller123: 3.10.65 is so old and insecure...

12:00 <KotCzarny> you forgot buggy and crappy

12:02 <apritzel> well, 3.10.65 in itself is not bad per se, just old, but the monster that Allwinner made of it with their modifications ...

12:05 <neller123> Ok. May be anybody knows about locations of files in AOSP, where resolution stored?

15:55 <jernej> neller123: I only added new resolutions on BSP kernels for older SoCs, but this should be similar:

15:56 <jernej> you have to add appropriate line to this structure: https://github.com/orangepi-xunlong/OrangePiH6_kernel/blob/master/drivers/video/sunxi/disp2/hdmi2/hdmi_core/api/edid.c#L21

15:56 <anarsoul> jernej: :(

15:57 <wens> anarsoul: on the other hand it has a DSP?

15:57 <jernej> neller123: and somehow add new id for it. I'm not sure about this step, but this table has something to do with it: https://github.com/orangepi-xunlong/OrangePiH6_kernel/blob/master/drivers/video/sunxi/disp2/hdmi2/hdmi_core/hdmi_core.c#L25

15:57 <jernej> neller123: I can't help you more

15:58 <jernej> anarsoul: it's like v3 replacement

15:59 <jernej> maybe ARM doesn't want license mali to non-ARM SoCs

16:00 <jernej> only RISC-V SoC with GPU that I heard of, has PowerVR GPU

16:01 <apritzel> jernej: I guess it defeats Allwinner's purpose in using RISC-V: they want to save license fees ;-)

16:02 <anarsoul> jernej: they could license vivante, it used to be installed on ingenic SoCs

16:02 <apritzel> but I guess this particular SoC is for smart speakers anyway, which have little use for a 3D GPU?

16:03 kop316 has joined #linux-sunxi

16:03 <jernej> why is there video decoding core then? :)

16:03 <jernej> and deinterlace core

16:04 prefixcactus has quit [Ping timeout: 252 seconds]

16:05 <jernej> it has G2D core though...

16:05 gaston1980 has joined #linux-sunxi

16:07 <apritzel> maybe it's not meant to run Android?

16:07 lkcl has joined #linux-sunxi

16:10 <apritzel> or they just couldn't find a usable GPU solution in time for this release ...
