vae.hpp: Replace free_compute_buffer with runner_done to fix memory not released - #1872
Merged
Conversation
free_compute_buffer does not seem to release all resources after the gen. Replaced free_compute_buffer() calls with runner_done() to fix subsequent generations failing due to insufficient memory that was not freed.

Upstream commits merged: - feat: support INT8 ConvRot safetensors (leejet#1857) - fix: fail with a message when MiniMax-H3 is run in img_gen mode (leejet#1863) - fix: preserve "token_refiner" token for MiniMax H3 LoRAs (leejet#1864) - fix: replace free_compute_buffer with runner_done in vae (leejet#1872) - sync: update ggml (leejet#1873) - fix(ci): trigger builds for ggml updates No conflicts. The local vae.hpp runner_done fix was byte-identical to leejet#1872. Local ClipProj/MiniMax-H3 support and server SSE streaming preserved.

Summary
In vae.hpp, free_compute_buffer() does not seem to release all resources after the gen. On some tight setups, this causes subsequent generations to fail due to insufficient memory that was not freed.
Replaced free_compute_buffer() calls with runner_done() to ensure all resources freed after a generation is done.
