clover: what kind of devkit? You got a second hand snapdragon devkit?
<icecream95>
robclark: Do you know why Freedreno's storage_8bit setting doesn't work on X1-85, when the Windows driver does expose VK_KHR_8bit_storage?
chrisl has joined #aarch64-laptops
<icecream95>
Does the blob just emulate the feature using 16-bit operations, or do GPUs older than a7xx_gen3 have a different way of encoding 8-bit instructions?
<icecream95>
(I've written a SPIRV-Tools opt pass which can emulate it in some cases, but am wondering whether I didn't need to bother.)

icecream95: hmm, we thought that was new in a750.. but I can double check. You could try setting `storage_8bit = True` in freedreno_devices.py and see if the deqp tests pass?
chrisl has quit [Ping timeout: 480 seconds]
<icecream95>
robclark: I haven't tried with deqp, but if I set that then 8-bit instructions seem to still be 16-bit... or at least the offset is still shifted left one bit
<robclark>
maybe blob emulates it somehow, I guess?
chrisl has joined #aarch64-laptops
chrisl has quit [Ping timeout: 480 seconds]
<icecream95>
I wonder if the compiler should check if 8-bit loads/stores are being used when it won't work, because otherwise applications not checking the feature bit looks like miscompilation
chrisl has joined #aarch64-laptops
<robclark>
I guess in theory validation layers would check that (but not sure if they do much spirv checking)
<leezu>
jglathe: have you tried installing linux alongside windows as in the chenguokai/tutorial-dev-kit-linux.md linked in your linux_ms_dev_kit repo? If I read your comments on Github right you usually install to external disk? I've got at 1TB Lenovo Ideapad 5 2-in-1 14Q8X9 (83GH) and curious to hear if you have any suggestions. I'm also wondering how you built your
<leezu>
Ubuntu_Desktop_24.10_Lenovo_Ideapad_5_2in1_6.16rc.img.xz. I assume you take upstream image and add kernel and dtbs? Anything else?

robclark: I guess I should have thought of that earlier... "SPIR-V contains an 8-bit OpVariable with StorageBuffer Storage Class, but storageBuffer8BitAccess was not enabled."
<icecream95>
Thanks for the reminder that validation layers are a thing...
<robclark>
heheh, np

leezu: All devices here have an install alongside Windows, only one from the Ubuntu Concept ISO. The image I use is for first bringup outside of the ISO, still fighting with the toolchain from time to time. I have an Ideapad 5 83GH (512GB) too, with manual install alongside Windows. Got sound activated there, still wrestling with the OLED display a bit.
<JensGlathe[m]>
I took the pre-installed desktop image for raspi and derived from there, many moons ago. Would need to redo for 25.10 (I guess) but hesitant to do so because its tedious. The only way for a real installer would be an ISO because they use Casper.
<JensGlathe[m]>
There will be a new image for the 83GH this weekend, I guess. And a wiki documentation on how to install on the local nvme.

<JensGlathe[m]>
If you want to help: Can you provide the hwinfo64 log for your device? A dmesg and lsusb might be useful after the new Image is up.

Yeah, it's a used project volterra devkit. Its like a x13s in a mac mini / intel nuc form factor

I will probably end up following Jens Glathe's kernel, but gonna try putting arch on it 😉

Hello, can you please tell me which steps I need to follow in order to enable microphone + internal speakers + webcam on my Dell XPS 9345 - running Kubuntu 25.04 with 6.16.0-12-qcom-x1 at the moment, but I have no idea how to add the patches from alexVinarskis. Looking forward to your help :-)
