  Hi,
  
  The bge driver doesn't support this chipset yet and I was wondering if

  NetBSD looks like it has support for it.  Now I may be wrong here, but
  it appears that the BCM57765 is similar to other devices based on the
  NetBSD if_bge.c source version 1.194.
  
  I've tried applying the NetBSD changes to the FreeBSD bge source but I
  don't know enough about the hardware and the code is different enough
  that I haven't made it very far.  I can get a patched 8.2 kernel to
  detect the device, complain that the ASIC is unknown, read the MAC
  address correctly and determine there is link but as soon as you attempt
  to ifconfig up the interface the machine locks up.
  
  I'm happy to try and port this over but need a nudge in the right
  direction from someone who knows the code.
  
 
 Here is experimental patch for BCM57765 family controllers. I
 don't have these controllers so the patch was not tested at all
 except compile. Recent Broadcom controllers like BCM57765 support
 EEE(Energy Efficient Ethernet) feature but it is not yet supported
 by the patch.
 Also it would good to see the output of pciconf -lcbv and dmesg
 after applying the patch.

FYI: Committed to HEAD(r221445).

I've been away from the machines with this chipset for the past week so
have not finished the testing, but can report that the initial tests I
did involving normal use, jumbo frames, v4 and v6 etc. all worked fine
and throughput was good.

Once I have done a thorough test of the NIC I will post a report here.

I tested it with both 57765X and 57785X. All seems to work as
expected. Jumbo frame performance also looks very good.

Ok, thanks in advance.

gdb scripts for mbuf leaks

2011-05-04 Thread Vijay Singh
Hi, I am trying to track down an mbuf leak caused by an in-kernel
custom application. Does anyone here have any gdb scripts that would
traverse the zone (zone mbuf in this case) and print out all objects
that are currently allocated?

-vijay

PS: I see the count of mbufs (current/cache/total) going up constantly.
