Summary by Sourcery

Give the virtgpu remoting frontend more time to initialize API libraries and emit a warning on timeout rather than triggering a fatal error.

Enhancements:

  • Increase the API remoting library load timeout from 200ms to 500ms
  • Log a warning when the API remoting call times out instead of fatally aborting

Summary by CodeRabbit

  • Improvements
    • Increased the maximum wait time for remote call responses, reducing the likelihood of premature timeouts.
    • Added a warning message to notify users when a remote call times out.

File(s) Change Summary
ggml/src/ggml-remotingfrontend/virtgpu.cpp Increased remote call wait timeout; added warning log on timeout.

Poem

The timer ticks, the rabbit waits,
For answers from the distant gates.
Five seconds now, not just two—
More time for GPUs to come through!
If silence falls, a warning’s shown,
So bugs won’t burrow all alone.

Consider including more context in the timeout warning.

Including the total wait time or relevant parameters in the warning would make it more useful for debugging and monitoring.
