Original GitHub issue: https://github.com/gopher64/gopher64/issues/466

My apologies if this is an obvious user error of some sort. But for me Gopher64 will always be stuck with window not responding after I tried opening up any game:

I'm on a Raspberry Pi 5, Duckstation works flawlessly on this. Based on that, I expected Gopher64 to be usable as well, but something seems to be going wrong;

Affected hardware: Raspberry Pi 5 (ARM64)

Affected operating system: postmarketOS Edge based on Alpine Edge

Affected Gopher64 version: v1.0.18 installed via Flathub

I'll be honest, I've never tested gopher64 on a raspberry pi, or even on ARM for that matter.

I may get around one day to picking up a Pi and troubleshooting it, but for now I don't really have any advice, I'm not sure what the issue could be.

The GPU of the Raspberry Pi 5 is rather weak, so perhaps that could be a factor? I know it supports Vulkan, but probably not the latest modern extensions. KDE Plasma 6 runs perfectly fine with all the usual 3d effects though, so 3d acceleration definitely works.

I decided to test with my Pi 5, I was unable to launch it on the stock Raspberry Pi OS with Bookworm so I tested with Ubuntu 25.04 and the GUI appears to run fine but on launching a rom it appears to crash the same way. I'm not sure what else to do to get more detailed logging but am up to help out if I can.

I successfully compiled in a Raspberry pi 5 with Bookworm and I get a similar console output as above with gopher64 not launching properly.

Can someone try to run a debug build, or cargo build --profile=release-with-debug and run it with gdb to see exactly where it crashed?

Looks like it's getting stuck somewhere in the main function (line 78), hopefully this helps.

I think it is just the case that the video card doesn't support VK_EXT_external_memory_host

VK_EXT_external_memory_host not supported or failed, falling back to a slower path.

I know that it lists it as a warning in the logs, but in the readme for parallel-rdp it says:

For integration in emulators, VK_EXT_external_memory_host is currently required

I don't think it works without that extension.

Maybe it's a bug in parallel-rdp, or possibly in the Raspberry Pi v3d driver implementation. When running vulkaninfo it prints this:

It looks like the extension is available so I guess it's just not being detected for some reason.

Update: I was looking at the wrong device apparently. That list was for the llvmpipe device (software renderer). Unfortunately, V3D does not currently support the VK_EXT_external_memory_host extension.

I tried to run gopher64 with GRANITE_VULKAN_DEVICE_INDEX=1 set and it actually works! However, the FPS is quite low as could be expected from a software renderer.

Looks like there is an open issue regarding this here, so at least they are working on adding it:
