Graphics programming • How to configure Rpi5 Vulcan heap size?

I'm trying to get VkFFT to run on an 4GiB Rpi5 and am having a call to VkAllocateMemory fail when trying to allocate a 1GiB buffer.

Using vkGetPhysicalDeviceMemoryProperties2 I see that on my Rpi5 that I have a single memory heap of size 2023 MiB with flags 1 on the V3D 7.1.7 Device. So maybe I need more memory in that heap?

Is it possible for me to increase that size?

Thanks!
