07:34 <dramforever> I think I've 'found' an undocumented Vivante GC300 on the SoC on a RISC-V board, specifically JH7100 on the VisionFive. Maybe it's just completely broken, but I thought to give it a try. If anyone is interested here's what I tried:

07:35 <dramforever> First I just made up a device tree node and booted with clk_ignore_unused so the GPU clock would be running. The etnaviv driver seems to initialize fine:

07:36 <dramforever> [ 27.950261] etnaviv-gpu 10100000.gpu: model: GC300, revision: 4635

07:36 <dramforever> [ 27.964005] [drm] Initialized etnaviv 1.3.0 20151214 for etnaviv on minor 0

07:37 <dramforever> But etnaviv_2d_test from libdrm fails in kernel space with a VM_BUG_ON in gfp_zone, seemingly because it's trying to allocate from one of the 'bad zones' (I have no idea about this area in Linux at all)

07:38 <dramforever> The trace is like this: https://fars.ee/ZixM

10:25 <shoragan> dramforever, is that board in stock somewhere?

10:44 <dramforever> shoragan: Vendor gives links here https://forum.rvspace.org/t/how-to-purchase-visionfive/37

10:45 <dramforever> I don't see if they have any in stock in the 'global' link: https://shop.allnetchina.cn/collections/starfive/products/starfive-visionfive-ai-single-board-computer

10:45 <dramforever> But the Mainland China link says 105 in stock https://www.iceasy.com/10210/1022722251.shtml

10:45 <dramforever> *104 in stock

10:46 <shoragan> dramforever, ah, thanks

10:48 <dramforever> It's... not a particular great value. I'm not sure what you'll need it for, but it's kinda obvious now that the VisionFive V2 is coming kinda soon, e.g. the box design they just shared https://redd.it/w53ju6

10:49 <dramforever> So might be a good idea to wait for that

10:49 <dramforever> shoragan: ^

10:50 <shoragan> ah :)

10:52 <dramforever> This is just what I gathered reading news and docs and whatnot, but the JH7100 was AFAIK meant to be a sort of 'beta' version to go into the BeagleV Starlight

10:52 <dramforever> The 'real' Starlight is meant to have the JH7110, i.e. what this V2 (presumably) has

10:58 <dramforever> Well, getting back on topic, the V2 has an Imagination Tech GPU, so you're also probably not going to see what I mentioned. See post on vendor forum: https://forum.rvspace.org/t/img-bxe4-32-gpu-open-source-plan/600
