[PATCH] arm64: dts: qcom: kodiak: increase fastrpc compute-cb session slots
From: Jianping Li
Date: Wed Apr 01 2026 - 03:43:03 EST
Some workloads on Kodiak can exhaust FastRPC sessions when multiple
compute clients open contexts concurrently, leading to -EBUSY failures.
Describe the compute context bank with qcom,nsessions = <5> so the
driver can provision enough session slots for the compute-cb instance.
