crash on AMD RADV TAHITI type DiscreteGpu #4

Closed aircable closed 2 years ago

aircable commented 2 years ago

Got an older Radon 7950 with the latest AMDGPU driver. But it crashes:

./run.sh stratum://0x76cB31Fdb28Ddf887AF3cA4A0f7786D02C86032a.worker1@us2.ethermine.org:4444

WARNING: radv is not a conformant Vulkan implementation, testing use only. Using device: AMD RADV TAHITI (type: DiscreteGpu) Using subgroup size: 64 Generating light cache (CPU)... Light cache generation done. thread 'main' panicked at 'called Result::unwrap() on an Err value: SpecViolation(1713)', src/main.rs:153:115

Any suggestion on what I can do here? I looked at your source code:

    let dag0_buf = DeviceLocalBuffer::<[u32]>::array(device.clone(), dag_words, BUFFER_USAGE, Some(queue_family)).unwrap();

but unfortunately I have no idea how to find or solve the issue.

You need 4.5GB or more VRAM. Zombie mode is not supported.

Thanks for your quick answer. Meaning the old Radeon HD7950 with 3G memory is not supported.
