Gemini PDA - Linux / Current status of mainlining efforts

« on: February 18, 2020, 04:37:08 am »

Altough I am interested in booting mainline Linux on the Gemini, I have no prior experience in Linux kernel development and only rudimentary understanding of how drivers interact with the hardware. So, I don't think I can make reasonable contributions in that regard...

Also, looking at the MediaTek proprietary codebase in the Gemian 3.18 kernel makes me feel like there is a lot to port to even get close to a useful barely working system on mainline... especially concering the display driver, I guess, which leaves debugging only possible via USB UART cable.

Concering the MT6771 chipset of the Cosmo, I don't plan onto getting one, so I wouldn't be able to test things there.

Gemini PDA - Linux / Can I access the Debian fs offline?

Hi there!

Are you still able to boot into Android? Maybe you can get access to the Gemian root partition from there - it's just normal ext4, so it should work I guess.

I had a look at your email to the list (which I'm watching now to see if relevant patches hit it...) and also the discussion going on there in September 2019 [1]

As I understand it, one can already boot mainline 5.3 or 5.4 to a busybox shell over UART via USB but the device starts overheating. Your latest effort of mainlining can be found in the gemian linux repo [2] and enables thermal management of the CPUs. You posted that on the list but for some reason there was no feedback there. Did I get this right?

Does the implementation of thermal management mean that one can now safely boot a Gemini with mainline without overheating?
As far as I get it, the linux-mediatek list is operating on rather high volume... is there any chance your (understandably rather long) email just drowned in the load? It would be great to see more support going upstream!

Either way, thanks a lot for both your effort and the useful information!

Hi there!

I have had a look onto different pages of mainlining efforts, but all of them don't contain a lot of information on what is working, what is not working and what needs to be working to be able to run a mainline kernel.

Does anyone have an overview of the linux mainlining efforts?

Best regards,
Nimrod
