I am trying to setup a development environment for vulkan on my snapdragon x elite arm laptop and would like some advice as to how I should deal with the fact that the vulkan sdk is x64 and I want to compile an arm 64 c application that uses vulkan.
#Vulkan SDK on arm? (Snapdragon X Elite)

also it would be very helpful if someone could explain what kind of "emulation" is going on to cause this output in GPU enumeration, are all the GPUs virutal or just the last two in the list?

Funny you should ask, the latest release of the SDK apparently included a beta ARM version. #news message

hey thanks ill check it out right now

My guess is GPU0 is talking to the GPU directly.
GPU1 is using a vulkan->DX12 compatibility layer to talk to the GPU.
GPU2 is using a vulkan->DX12 compatibility layer to talk to the MS CPU implementation of DX12.

beta arm64 sdk seems legit, some of the binaries it ships with are still x64 but good enough for me

which binaries? I have a hand in the ARM sdk stuff so would like to know what else needs to be made arm64 native.

the vulkan capabilities is the only one i have found so far (so i was stretching the truth when i said "some of them"), i check with task manager so its harder to check some of the other binaries as they open and close so quick

dumpbin /headers should list arm64 (arm64X) if they are built with emulation in mind FYI (need to open up a developer command prompt to get dumpbin in the path)
maiden cape
yeah that

okay Ill run it and send output
looks like they are all arm64, so maybe i just have the old vulkan configurator from my previous sdk that I overwrote with the new arm one?
actually I think i ran the wrong command
river kayak
yeah that
okay, sorry i finally figured out how to use the command, its just the one executable:

seems like ONE thing is x64, rest is arm but not everything is arm64x...
river kayak
the x64 is the configurator
maiden cape
idk, I run the command one binary at a time
