Importing external semaphore not working under linux

[Snektron]

Attempting to import an external semaphore always returns hipErrorInvalidValue under Linux:

#include <hip/hip_runtime.h>
#include <iostream>
#include <cstdlib>

int main(int argc, char* argv[]) {
    hipExternalSemaphoreHandleDesc desc = {};
    desc.type = hipExternalSemaphoreHandleTypeOpaqueFd;
    desc.handle.fd = 0;

    hipExternalSemaphore_t external_sem;
    hipError_t result = hipImportExternalSemaphore(&external_sem, &desc);
    if (result != hipSuccess) {
        std::cerr << "error: " << hipGetErrorString(result) << std::endl;
        return EXIT_FAILURE;
    }

    std::cout << "success" << std::endl;

    hipDestroyExternalSemaphore(external_sem);

    return EXIT_SUCCESS;
}

$ hipcc -oexternal_semaphore external_semaphore.hip
$ ./external_semaphore
error: hipErrorInvalidValue

Note: This is not caused by the external fd being incorrect, as the code path executed by hipDestroyExternalSemaphore hits NullDevice::importExtSemaphore:

$ gdb ./external_semaphore
$ b NullDevice::importExtSemaphore
$ r
Breakpoint 1 at 0x7ffff70d6da0: file /nix/store/v954yk0ng3hz50ppmf8ax1jfxhcfzgxq-rocclr-5.2.3/cmake/../device/rocm/rocdevice.hpp, line 237.

Here is a more complete example (but im not sure if its correct) that attempts to construct a proper semaphore fd:
external_semaphore.txt

$ hipcc -oexternal_semaphore ./external_semaphore.hip -I /usr/include/drm -ldrm
$ ./external_semaphore  /dev/dri/renderD128 
error: hipErrorInvalidValue
