People,
I recently added a Sun dual gigabit, dual scsi PCI card to one of my
B2000s. This board contains 2 cassini chips, and a 53c896, all sitting
behind an Intel (well, Digital) 21154 PCI bridge.
The system works fine, but I'm seeing the following problems:
Whel probing the SCSI part of the board, the kernel spits the
following:
PCI: resource not parented! [2000-2fff]
PCI: resource not parented! [fb000000-fb5fffff]
And if I look at /proc/ioports :
00000000-00001fff : PCI00 Ports
00000020-0000003e : pic1
000000a0-000000be : pic2

00002000-00002fff : PCI Bus #02
00002000-00002fff : PCI Bus #02
[... ad nauseam].
Something looks bad here... Does anybody have a clue about this? lspci

Which kernel version?

This is definitely a bug.

Looks like PCI bridge support isn't parenting the allocation
of these resources correctly.

Wow! 2M? That's a fair chunk of space for a NIC.
Any special about that RAM or what it's used for?
(Just curious)

Is CONFIG_SCSI_SYM53C8XX_MMIO enabled in your kernel?
(again just curious)
thanks,
grant

Sorry. This is 2.6.17-rc1-pa1, but I saw this problem with 2.6.16 and
late 2.6.15-rc* as well.

Cassini looks like ad odd beast. RAM seems to be used at least to
download filters to the card, so the NIC can parse complete packets
and do a lot of ugly things, none of them being supported on Linux at
the moment (and probably won't ever). Have a look at
driver/net/cassini.[ch] if you really want to know... ;-)

Indeed:
maz@ashes:~$ zgrep SYM53C8XX /proc/config.gz
CONFIG_SCSI_SYM53C8XX_2=y
CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE=1
CONFIG_SCSI_SYM53C8XX_DEFAULT_TAGS=16
CONFIG_SCSI_SYM53C8XX_MAX_TAGS=64
CONFIG_SCSI_SYM53C8XX_MMIO=y
If there's anything you want me to test, feel free to ask. This is an
expandable box, and I can reboot it remotely.
Thanks,
M.
