IXGB networl driver and locking

Hi all, Same lock is being used in ixgb_intr and ixgb_start. If we get Receive interrupt while processing Xmit (ixgb_start), Will the calling of ixgb_intr() handler be delayed as we will not be getting lock in ixgb_intr since it is already locked in ixgb_start. If it is the case, are we making i

RE: IXGB networl driver and locking

Thanks for the reply. Sorry garbled URL in the previous message. Actually I was talk between the ixgb_start (Transmit function not the Transmit interrupt handler) and rx interrupt handler function ( Where we send the packet up using if_input function). We are using same lock between transm

RE: Reading a configuration file from a driver code during intialization.

Hi Mark, As I mentioned in the previous mail, the main issue is to read a Configuration parameter file from driver code. I am already using Sysctl variables as mentioned below, Currently I have written a small kernel module that will create a sysctl variable and update with a default value.

Query on SPIN Mutex in FreeBSD.

Hi, I have a query regarding the mutex lock in network driver, When I was browsing all network drivers in FreeBSD, I found none of the drivers are using MTX_SPIN, instead all of them are using MTX_DEF. When I read the man page of the mutex, it is mentioned that we need to use MTX_SPIN in pri

Regarding Jumbo frame implementation in bge

Hi, In bge driver, we have BGE_JUMBO_FRAMELEN defined to 9018. if_bgereg.h:#define BGE_JUMBO_FRAMELEN 9018 This macro is used to allocate the memory for jumbo buffer. If I have a MTU size of 2000, still bge will allocate the jumbo buffer of size BGE_JUMBO_FRAMELEN. Instead can we make the size
