Orangepi2/plus2/PC H3 Linux mainline support

pgauret

Happy to see progress on the mainline H3 support. We may finally have a proper kernel for our Orange PIs.

@faddat could you please post the results of a dmesg and cat /proc/cpuinfo so that we can get a sense of what works or not with these latest patches?

I am not @faddat, but if for you it's the same I can post it if you want.
No worry It's free!
dmesg and cpuinfo output


still a long way to go.

Jens has published the V4 series of his previous patches:

clk: sunxi: Let divs clocks read the base factor clock name from devicetree
clk: sunxi: Add H3 clocks support
pinctrl: sunxi: Add H3 PIO controller support
reset: sunxi: Add Allwinner H3 bus resets
dts: sunxi: Add Allwinner H3 DTSI
dts: sun8i: Add Orange Pi Plus support

This time patches applies cleanly, no manual intervention needed


For your info (copied from the linux-sunxi mailinglist):

This is v4 of my patch series introducing basic kernel support for Allwinner's
H3 SoC. It mainly adds basic clocks, resets and pinctrl. It also adds
interrupts, timers, watchdog, RTC, dmaengine, MMC and UARTs, which are mostly
compatible to those in earlier SoCs like A23 and A31, and can simply be reused.

Changes since v3:
- add a clock driver specific to the bus gates instead of listing parents in
  the DTSI
- skip the holes in the reset controller with of_xlate()

Ok guys i'm very new to Linux what does mainline mean?  Better GPU?

makama80

Nope. The GPU is as good (or bad) as it is. That cannot be changed. What could change is better support from the manufacturer of H3 SOC. Allwinner has a license to integrate the Mali, but Allwinner is obviously a hardware maker, not a software company.

So we depend on the community here and at linux-sunxi.org. Also Xunlong (manufacturer of the orange pi boards) seems to be focusing more on hardware than software development. Correct me if I'm wrong....

Okay, having another go at this.  Abandoning my old script, clearly it was doing something wrong.  In total, I got one boot, which I think was really only possible because I'd done some things outside of hte script.  So, here goes Sunday night....

@faddat
trash your script and do it by hand, at least you learn something.
tomorrow this wiil change with new patches and you need to modifiy your script.

@fritz:

That's the plan:

me, the source code, and the interwebs, should be able to tackle this challenge.  Once I'm done with that, I install Kubernetes on them, tell some folk to f-off, and thank others for their support, then make a necklace out of the kubernetes cluster using the ethernet cables that hold it together to use as a totem to ward off evil spirits.

mainline kernel support is needed for H3 chip as well as Mali400 GPU driver. Seems like an obstacle for us.

faddat

They're working on mainlining the H3, and progress seems quick.  as for mali.....
