Actually, the piece you might be interested in is specifically Hardware Timestamping, which is used by PTP. PTP's primary purpose is to sync clocks on a network, which might be of no interest to you.
Check out "ptp4l" for some sample code on how to use/access the 1588 clock. -----Original Message----- From: Ertman, DavidX M [mailto:[email protected]] Sent: Tuesday, September 03, 2013 11:37 AM To: Rajesh Cc: [email protected] Subject: Re: [E1000-devel] Give priority to the (software) time stamping thread in e1000e Have you looked at PTP (IEEE 1588-2008), which uses the hardware clock to timestamp packets as soon as they leave or enter the interface? If you are looking for maximum accuracy this might be of interest to you. -----Original Message----- From: Rajesh [mailto:[email protected]] Sent: Friday, August 30, 2013 2:53 AM To: [email protected] Subject: [E1000-devel] Give priority to the (software) time stamping thread in e1000e Hi, I am new to linux programming. I have an intel NIC with e1000e driver. I am working on precise time stamping of packets being captured from a network. An interrupt is generated at every packet reception. Thus an interrupt handler registered by the driver queues the captured packets and timestamps it. My question is If want to use RT Linux how can I increase the priority of the time stamping thread. Is this possible? ------------------------------------------------------------------------------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
