[PATCH v10 10/10] sandbox: trace: Increase trace buffer size

Sughosh Ganu sughosh.ganu at linaro.org
Sat Aug 12 17:30:24 CEST 2023


When running the trace test on the sandbox platform, the current size
of 16MiB is no longer large enough for capturing the entire trace
history, and results in truncation. Use a size of 32MiB for the trace
buffer on the sandbox platform while running the trace test.
