A blog for kernel development

2022-03-04 Thread Amit Kumar
Hi, I have started this mail thread to interact with other kernel learners. I am also running a blog for stuff related to Linux kernel development. https://blog.freeark1.tv When a new post will appear on this blog I'll mail it on this thread. Soon I'll start posting about kernel development.

USB CDC performance test

2022-03-04 Thread Mithran B
Hello, In Host and Gadget systems, enabled the USB CDC drivers. Then nodes are created as /dev/ttyAcm0 and /dev/ttyGs0. Then opened the nodes and write and read back the data. It is working. I want to test the performance of this interface and drivers. Do we have any utility for this? How to do
