SDL_HINT_GPU_DRIVER vulkan unsupported

[mhnaufal]

Hi!
I tried to create an Android app that uses Vulkan from SDL3. I stumbled with the issue SDL_HINT_GPU_DRIVER vulkan unsupported when calling SDL_CreateGPUDevice().
I already installed vulkanCapsViewer app and built the vulkan android example (https://developer.android.com/ndk/guides/graphics/getting-started), and both are working on my phone, but not for the SDL3. Do you have any idea how to solve this? Thanks

I called SDL_GetGPUDriver() and get "vulkan" as result.

My repo code: SDL_CreateGPUDevice(SDL_GPU_SHADERFORMAT_SPIRV, false, temp_driver_name.c_str());

As per the wiki: https://wiki.libsdl.org/SDL3/CategoryGPU#system-requirements

Requires Vulkan 1.0 with the following extensions and device features:
- VK_KHR_swapchain
- VK_KHR_maintenance1
- independentBlend
- imageCubeArray
- depthClamp
- shaderClipDistance
- drawIndirectFirstInstance
- sampleRateShading

We recently merged a PR that allows some of these features to be turned off: #13016

So you could try disabling the features that your device does not support and making sure your app does not use the disabled features.

[mhnaufal]

Thanks! Is there an ETA for when that PR will be included in a Release?

[thatcosmonaut]

Probably some time next week.

[slouken]

This PR was merged for the 3.4.0 release which currently doesn't have an ETA. We could potentially backport it to 3.2.x if it's important, but we'd need to fix #13138 and http://github.com/libsdl-org/SDL/issues/13139 first.

[thatcosmonaut]

Ah my mistake, I didn't realize this wasn't backported.

[slouken]

Ah my mistake, I didn't realize this wasn't backported.

Do you think it's worthwhile to backport?

[thatcosmonaut]

I think it's fine to leave it until 3.4 honestly.
