People like this one are the reason why I'm considering deleting the sm7150-mainline chat and doing development just for myself. I'm so sorry for not being at feature and stability parity with an Android OEM worth billions of dollars. I'm just one guy having fun tinkering on this, and you come to insult my work that was done in my free time, for you, for free? That's so fucked up

okay, I have the entire camera pipeline powering up fine on SM7150 now, but trying to get an image from the sensor with v4l2-ctl hangs... I'm way too sleepy to debug this further and also don't really know what to do

TL;DR: Microsoft locked Rust to 1.89 in GitHub Actions because some user reported that his code (with warnings configured as error, which is not the default) now errors because a new warning was introduced

One more U-Boot port done and fully working 🥳
Since SM8150 is supported upstream already, this was quite literally just writing a rather simple devicetree :)

TIL: Ever wanted to compress data or use cryptographic algorithms but you don't want to link to C libraries or you're just plain lazy?
The Linux kernel has you covered! Create a socket of type AF_ALG, bind to your favorite algorithm, send() in your data and recv() it back!
This seems to support deflate, SHA, RSA and some more on ppc64le and additionally even zstd, chacha, lzo, hmac and more on ARM!

@npub1w2v…20de and me had some time today to continue our work on U-Boot + Mainline for the RK3588S2 Radxa CM5 IO - it now boots to system with EFI and the only proprietary component on the way there being the DRAM init. Way to go!

sooo our sm7150-mainline kernel (and therefore also U-Boot) currently supports:
- Xiaomi Mi 9T / Redmi K20
- Xiaomi POCO X3 NFC
- Xiaomi Redmi Note 10 Pro
- Xiaomi Mi Note 10
- Xiaomi Mi Note 10 Lite
- Google Pixel 4a
and will soon also support:
- Xiaomi Mi 11 Lite 4G
- Xiaomi Redmi Note 12 Pro 4G
- Samsung Galaxy A71
- Samsung Galaxy A80
not gonna lie, seeing people take this and adapt it to their own devices makes me so happy :3

update: only the first boot is painfully slow, second one onwards is actually quite okay. Still wouldn't recommend ^^

postmarketOS booted from a USB stick on the Mi 9T - how can you tell? Because the internal UFS storage is only 128GB large. Don't do this at home though, it's USB 2 and booting takes AGES

overall I think your criticism is rather unfounded and I think the more constructive version of the comment about the GTK situation would be expressing hope for e.g. the pinephone pro perhaps seeing bugfixes for GLES 3.1 due to ecosystem adoption of the standard? I still don't really get your original intent...

2025-03-31 01:00:56 UTC

"Device X has driver issues but the hardware is capable" (be it bugs or just no driver at all yet in the case of your Asahi example) IMO is not valid criticism of GTK's choice of target APIs. Most importantly, the devices have the capability to run the newer APIs, so it reinforces the case for choosing them; second of all some specific devices having bugs is an exception to the rule and those shouldn't be reason hold back the ecosystem from adopting decade-old standards

your take regarding OpenGL ES 2.0 is weird, that's a standard from 2007, now 18 years old. It's definitely not anything from "relatively new hardware". Qualcomm Adreno and ARM Mali GPUs have supported OpenGL ES 3.0 since 2013, if anything "relatively new" doesn't support it, the hardware simply isn't "relatively new", it's just dead on arrival

- This should probably become a more regular thing, I'm considering turning one open evening at CCCAC every month into a "Mainlining Evening" for people interested in hacking together
- We need more beginner friendly, accessible documentation for Mainlining, my presentations are hopefully an OK entrypoint, but I can do better
- https://wiki.mainlining.org needs love
- Oh and I forgot: We got an msm8916 device booting lk2nd and hopefully Mainline soon!
This is only the beginning!

- Udev rules and pmbootstrap didn't play well for one person and we couldn't figure it out in time, that sucked
- MSM8996 needs a lot of work but I didn't have the time to look after them too much :(
- It is damn hard to explain this to people with almost no technical knowledge in this area, but we tried our best and they learnt a lot
- Not everyone had success, but everyone went away with new knowledge and hopefully excitement to keep going

Initial workshop afterthoughts and notes, will write something more in depth later on the soon-to-come mainlining.org blog:
- 1 Xiaomi tablet now boots mainline quite well and can boot to system from UFS
- 1 Xiaomi phone can now boot mainline but fails early for yet unknown reasons
- 1 Samsung phone now has a uniloader port and can boot mainline but crashes early (on first try!)
- Motorola milestone is a long term project that research has been started on

I made #PostmarketOS boot on PowerPC! And discovered a bunch of bugs in pmb v3 and a circular dependency on the way here. If it weren't so late I'd build some GUI as well, but that's for another day.

That's a way different chipset, plus I don't own one :( It's Mediatek though and the manufacturer sadly ceased operations, so I think your hopes of getting anything usable in the near future are probably slim unless someone finds a used one and decides to work on it (you never know!)

2024-08-18 20:49:19 UTC

they were! The best part about these is that they have secure boot disabled so we can use lk1st (I wanted UART for debugging lk1st)! And potentially other stuff, at some point I wanna try looking into patching some firmware to "enable" EL2 for us, sadly MSM8953 makes this much less trivial than MSM8916, but I have some hopes
