Broadcomm BCM4401-B0 and memory upgrade issue.

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

After the memory upgrade on my Laptop (HP nx5000) FreeBSD 6.0 stable,
the driver for NIC bfe0 (Broadcom BCM4401-B0) stops working. The NIC LED
lights are on. The bfe0 interface is up and active. However, I got a
permanent message on the console:

bfe0: watching timeout -- resetting.

This occurs in the case when I compile the new kernel without bfe driver
and load the bfe driver as module (if_bfe.ko). In the case when the
driver is compiled into the kernel, the system stalls during the boot or
whenever I try to configure the interface.

This behavior is reproducible on FreeBSD 6.0 RELENG_6 stable compiled
from checkout on 02.11.2005 and also from checkout on 23.01.2006. 

The problem occur only if the upgraded memory (RAM) exceeds 1GB. It does
not depend on the manufacturer of the memory chips and the number of
occupied slots. I already tried 2 1GB modules from Infineon DDR400 CL3
and two modules from Crucial DDR333, CL2.5. It also does not depend on
ACPI.

The problem does not occur under Windows XP.

What should be my next steps, in order to get NIC working?
Can I try NDIS for this NIC?

Any ideas are welcome. Thank you.

Here is the dmesg output before upgrade and after.

This problem has a familiar ring to it. Unfortunately, I don't own any
machines that have this chipset built in, and they don't make any standalone
cards that have it so I can't buy one. This means I can't test it
myself.
However, you can try the following:

- Bring up /sys/dev/bfe/if_bfe.c in your favorite editor.
- Find the bfe_dma_alloc() routine, and you should see code that looks
  like this:

static int
bfe_dma_alloc(device_t dev)
{
        struct bfe_softc *sc;
        int error, i;
 
        sc = device_get_softc(dev);
 
        /* parent tag */
        error = bus_dma_tag_create(NULL,  /* parent */
                        PAGE_SIZE, 0,             /* alignment, boundary */
                        BUS_SPACE_MAXADDR,        /* lowaddr */

                        &sc->bfe_parent_tag);

- Change it to look like this:

static int
bfe_dma_alloc(device_t dev)
{
        struct bfe_softc *sc;
        int error, i;
 
        sc = device_get_softc(dev);
 
        /* parent tag */
        error = bus_dma_tag_create(NULL,  /* parent */
                        PAGE_SIZE, 0,             /* alignment, boundary */
  /* change this -> */  0x3E7FFFFF /*BUS_SPACE_MAXADDR*/,        /* lowaddr
*/
                        BUS_SPACE_MAXADDR_32BIT,  /* highaddr */
                        NULL, NULL,               /* filter, filterarg */
                        MAXBSIZE,                 /* maxsize */
                        BUS_SPACE_UNRESTRICTED,   /* num of segments */
                        BUS_SPACE_MAXSIZE_32BIT,  /* max segment size */
                        BUS_DMA_ALLOCNOW,         /* flags */
                        NULL, NULL,               /* lockfunc, lockarg */
                        &sc->bfe_parent_tag);

- Save if_bfe.c
- Recompile if_bfe.ko and/or your kernel, test it, and report back what
  happens.

Wait, let me say that last part again: REPORT BACK WHAT HAPPENS! I hate
it when I send people things to test and they vanish into a black hole,
never to be heard from again.

I suspect this chipset has a DMA limitation that prevents it from
performing DMA to/from any addresses outside the first 1GB of RAM.
Curiously, I ran into this with a Linksys wireless NIC with the
NDISulator, which is based on a Broadcom chipset too (802.11b only).
> Can I try NDIS for this NIC?
The NDISulator is known to work with this chip. But try the fix above
first.

Broadcomm BCM4401-B0 and memory upgrade issue.

I am CC this to a few people on the freebsd-current list that had
somewhat simular symptoms with other hardware.
		-----
Have you tried to boot with the old contigmalloc using the sysctl
option "vm.old_contigmalloc=1"?

Some people are seeing slow boot/configuration with new style
vm_page_alloc_contig/contigmalloc.

I am doing some profiling of vm_page_alloc_contig() and have found
that larger physical memory configurations makes these problems much worse.

I identified 4-5 places that can be changed to decrease the number
of page tables that is needed to be checked before an allocating a range.
Some of the changes will only occasionally save a few page checks, but
others changes could save several hundred or more page checks on every call.

The old contigmalloc could be optimized also, but it uses the lower
addressed physical pages, which turns out to be used less during the
boot process than the upper addressed physical pages.

Broadcomm BCM4401-B0 and memory upgrade issue.

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

I applied the suggested changes.
I got the following message when I load the if_bfe driver.

vm_page_alloc_config: alignment must be a power of 2

After that the kernel panics and system reboots.

I think, if I can specified the allignment correctly, it should work.
Tell me, how to do this, and I will try it again.

LM

Broadcomm BCM4401-B0 and memory upgrade issue.

Hi,

The chip is indeed unable to do DMA > 1G, as seen in the linux driver
from Broadcom:

[...]
v3.0.11 (Aug 03, 2005)
=====================
     Fixes:
     -------------
        1. Problem: (CQ #13593) 4401 hangs when dealing with memory
                    addresses above 1G.
           Cause  : Hardware DMA limitation.
           Change : Modify the code to ensure memory addresses are
                    below the 1G ceiling.
           Impact : None.
[...]
See <http://www.broadcom.com/support/ethernet_nic/downloaddrivers.php>,
under BCM4401 drivers.

     $.02,
     /Mikko
