notes

Dual Arc Pro B70 with P2P working; llama.cpp crashes in dev2dev_memcpy with DEVICE_LOST under --split-mode tensor, and a related issue (28778) records the DFlash2 draft model triggering a Windows GPU driver TDR reset (VIDEO_TDR_TIMEOUT_DETECTED) on the same dual-card setup. Companion issue 27168 records ur_die 'Experimental P2P feature is not implemented for OpenCL adapter', so the OpenCL runtime path lacks P2P entirely.
