How to improve G2G latency

Do you have any ideas for optimizing G2G latency.Is there still optimization in the v4l2 transport layer
On jetpack 5.1.2 package.

hello 525554536,

may I know what’s your current test results, and what’s your expectation of G2G latency.

Expected to reach below 60ms. What is the current performance limit with the 1080P sensor.

hello 525554536,

the evaluation results of glass to glass latency for 4K 30-fps camera use-case is around 100ms.

you may try increasing the ISP clock to have better performance,
for example,
# echo 1 > /sys/kernel/debug/bpmp/debug/clk/isp/mrq_rate_locked
# cat /sys/kernel/debug/bpmp/debug/clk/isp/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/isp/rate

There is an ISP inside the camera, but there is no ISP using SOC

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

hello 525554536,

may I know what’s your current measurement results.
