Hi all, I would like to develop a pci based device driver for a LAN (Ether express)card. But I am not getting any Software manual for it. If anyone has a user manual for the same, then kindly send it to me. Also can I get the data sheet and user manual for the ATM card ENIL 155P. I saw the source for the same in eni.c in drivers/atm. Thanks & regards, Mouli. -----Original Message----- From: kernelnewbies-bounce@nl.linux.org [mailto:kernelnewbies-bounce@nl.linux.org]On Behalf Of Huo Zhigang Sent: Monday, 29 April 2002 9:10 AM To: kernelnewbies@nl.linux.org Subject: What is the cost of a system call(send the 2nd time) Howdy, Now, I am trying to estimate what the cost of a system call, To be more accurate, how many instructions have to be executed in average. To what extent dose the cost diff among different platforms? So many high-perf communication systems are implemented in user space, just to bypass all kinds of system calls. Could we make a thin system-call-layer to ease the life of guys in these efforts? TIA. ------------------------------------------------------------------ I18n of linux is necessary now.
