Subject: [PATCH] arm64: dts: qcom: kodiak: increase fastrpc compute-cb session slots
Date: Wed, 1 Apr 2026 15:33:45 +0800 [thread overview]
Message-ID: <20260401073345.478-1-jianping.li@oss.qualcomm.com> (raw)
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.
