I write 1 video driver, 2 audio drivers and porting usb driver on my embedded system. I intend to check the system performance when I read steam from usb, play it and and store it back with different video format. The performance I want to focus are "memory leak", "cpu usage" and "memory usage" on different task. Would you please tell me where I should start from and anything I need to take care about? appreciate your help, miloody -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
