Terry, Thank you for your input. I understand the situation quite well. That the card won't ping is not a complex bug that is difficult to track. We are talking basics here. I appreciate very much Yongari's volunteering of his time and if I were a network driver developer I would jump...

The new driver does not work. It is only successful at ping 90% of the time and then the error "network is unreachable" occurs. Please provide an update and an ETA for the complete driver.

Hi, I have an application running in user-mode on a multi-homed host under FreeBSD 9.0 that performs a lot of UDP/IP I/O with other multi-homed hosts. After running for about one hour (exchanging more than 500GB of data) a single sendto will get a EHOSTDOWN error. The target host is most...

Thank you very much for the status update. I'll monitor this thread for further updates.

I got his reply to a query on the Broadcom web site. Can the maintainer of this driver comment on the status of the integration of the R720 support for iDRAC? Availability within the next few days would be really sweet.

Still no luck. All four NIC ports are detected at boot time but I am unable to ifconfig any port. I get the following error messages: NMI ... going to debugger[/font] ->repeated four times kernel: NMI ISA 20, EISA ff I did the following: # svn checkout svn://svn.freebsd.org/base/stale/9/...

Thank you Terry for the reply. Initially the four NIC ports were not recognized with the release of FreeBSD 9.0 so I simply got the latest copies of the bge driver and made a kernel. This kernel was able to detect the BCM5720 NIC's four ports but I got NMI errors when I tried to ifconfig the...

Is there an update on the driver for the BCM5720? We just got a R720 from Dell and need to get the driver update to run FreeBSD 9.0.

Yes, you are right. I really meant to ask about rNICs that support iWARP as they offload UDP checksum calculations as well as multicast (by group filtering?). The issue is really latency for me.

I'm trying to improve the performance of my application that does a lot UDP/IP multicast. It seems that new NICs supporting iWARP would help. Is iWARP supported under FreeBSD?

Solved Valgrind works great under FreeBSD 8.1

Thank you Thank you very much. I'll keep monitoring the progress.

Thank you Joel. Could you direct me to the project pages/wiki? I'm hoping to find out the beta ETA and what ib h/w the project will use as a reference/initial implementation. Thanks,

I am interested in moving away from Ethernet to Infiniband but I have found no trace of Infiniband support under FreeBSD. Can anyone recommend a hardware/software solution for FreeBSD 8.1? Thanks.

I have a user-mode application that is single sourced with Linux/Solaris. It works great on Linux and Solaris but keeps growing its memory usage under FreeBSD. It passes valgrind under Linux but valgrind under FreeBSD does not work properly so I used dmalloc to check it and found memory...

That may work but I am concerned that I don't know when a buffer address is in userland or kernel space. The kernel should know so I'll give it a shot. Thank you.

I am writing a kernel module that gets I/O requests from kernel modules (buffers are in UIO_SYSSPACE) as well as userland (buffers are in UIO_USERSPACE). I cannot tell where I was called from so it is not possible for me to correctly configure uiomove when I want to read/write the buffers...

The problem is solved. I added to module B MODULE_DEPEND(A) and func1 and func2 are resolved and I can load module B after loading module A.

I have the following setup: 1. Module A: File A.h that defines func1 and func2 as follows: int func1(int flag); extern int func2(int flag); /* try extern as well. */ File A.c declares func1 and func2 as follows: int func1(int flag) {return flag;} int func2(int flag) {return flag;} 2. Module...

I have developed two modules (A & B) where B depends on A. Module B needs to call function func1 provided by module A. I successfully kldload module A first, but I cannot load module B due to a linker error: kernel: link_elf: symbol func1 undefined How do I mark func1 for export in module A...
