First off I'm quite new to Gentoo.

I have a Chelsio T420-BT that doesn't seem to want to initialize. The kernel reports that the physical/virtual functions (SR-IOV) appear to initialize but the physical NIC itself doesn't. There were some kernel warnings that I don't understand:

Kernel log:
full kernel log here
0000:01:00.4 is the physical NIC in question.
0000:01:00.0 -> 3 are the 'physical functions'

Code:

blinky,

Welcome to Gentoo.

Notice that
Code:
01:00.5 SCSI storage controller [0100]: Chelsio Communications Inc T420-BT Unified Wire Storage Controller [1425:4509]
   Subsystem: Chelsio Communications Inc T420-BT Unified Wire Storage Controller [1425:0000]
01:00.6 Fibre Channel [0c04]: Chelsio Communications Inc T420-BT Unified Wire Storage Controller [1425:4609]
   Subsystem: Chelsio Communications Inc T420-BT Unified Wire Storage Controller [1425:0000]
there are no drivers loaded for those elements of your card, so they won't be working just now.

Grepping the kernel source for your vendor ID
Code:
/usr/src/linux $ grep -R 1425 ./
produces one interesting hit is the SCSI region of the code.
Code:
./drivers/scsi/csiostor/csio_hw.h:#define CSIO_VENDOR_ID            0x1425

That's a SCSI driver that matches your vendor ID.

That file header says
Code:
/*
 * This file is part of the Chelsio FCoE driver for Linux.
which looks promising too.
Reading the Kconfig file in that directory shows.
Code:
 config SCSI_CHELSIO_FCOE
        tristate "Chelsio Communications FCoE support"
        depends on PCI && SCSI
        depends on SCSI_FC_ATTRS


Looking in your kernel .config shows that the symbol SCSI_CHELSIO_FCOE does not appear, so you don't have that driver built.
However, we know it depends on SCSI_FC_ATTRS
Code:
# SCSI Transports
#
CONFIG_SCSI_SPI_ATTRS=y
# CONFIG_SCSI_FC_ATTRS is not set
which is off, so the option is hidden.

Rebuild your kernel, using menuconfig to enable CONFIG_SCSI_FC_ATTRS which is a menu, then inside that menu, enable SCSI_CHELSIO_FCOE.
That should fix the Fibre Channel Over Ethernet part of your card.

Hi, thanks for taking the time to show the steps you took - invaluable information.

I deliberately didn't compile the modules for those device because I didn't think I needed them. The NIC on the card is a standard ethernet RJ45 (which is how I intend to use it) and it is function #4 - the device having the issue:

full (pci bus 01) kernel log here
Code:

[  +0.000169] pci 0000:01:00.4: [1425:4409] type 00 class 0x020000

[  +0.000144] cxgb4: probe of 0000:01:00.4 failed with error -16


Pardon my ignorance, and I hope you can correct me here, but would the improper initialization of other functions cause the bad behaviour seen here? More succinctly: is it necessary for all the other functions to be properly working in order for any of them to work? Function #6 is the FCOE offload device which I have no intention of using.

However, I compiled in support for it:

Code:

01:00.5 SCSI storage controller [0100]: Chelsio Communications Inc T420-BT Unified Wire Storage Controller [1425:4509]
   Subsystem: Chelsio Communications Inc T420-BT Unified Wire Storage Controller [1425:0000]
01:00.6 Fibre Channel [0c04]: Chelsio Communications Inc T420-BT Unified Wire Storage Controller [1425:4609]
   Subsystem: Chelsio Communications Inc T420-BT Unified Wire Storage Controller [1425:0000]
   Kernel modules: csiostor


Although I was unable to get the iSCSI offload function working (I won't be using it): again, do you think I need this working for the whole card to function properly?

full kernel config here
Code:

CONFIG_SCSI_FC_ATTRS=y
# CONFIG_SCSI_CXGB3_ISCSI is not set
CONFIG_SCSI_CXGB4_ISCSI=m
CONFIG_SCSI_CHELSIO_FCOE=m
CONFIG_NET_VENDOR_CHELSIO=y
# CONFIG_CHELSIO_T1 is not set
# CONFIG_CHELSIO_T3 is not set
CONFIG_CHELSIO_T4=m
CONFIG_CHELSIO_T4_DCB=y
CONFIG_CHELSIO_T4VF=m

blinky,

From your first post,
Code:
01:00.0 Ethernet controller [0200]: Chelsio Communications Inc T420-BT Unified Wire Ethernet Controller [1425:4009]
01:00.1 Ethernet controller [0200]: Chelsio Communications Inc T420-BT Unified Wire Ethernet Controller [1425:4009]
01:00.2 Ethernet controller [0200]: Chelsio Communications Inc T420-BT Unified Wire Ethernet Controller [1425:4009]
01:00.3 Ethernet controller [0200]: Chelsio Communications Inc T420-BT Unified Wire Ethernet Controller [1425:4009]
01:00.4 Ethernet controller [0200]: Chelsio Communications Inc T420-BT Unified Wire Ethernet Controller [1425:4409]

Notice that function 4 has a different deviceID, 4409, compared to functions 0..3, 4009, which says that in some way or another, its a different device.

The Chelsio website shows 1.15.37.0 as the latest firmware.

Code:
$ ls -l /lib/firmware/cxgb4
total 2608
-rw-r--r-- 1 root root 179202 Jul 31 12:02 aq1202_fw.cld
-rw-r--r-- 1 root root 208900 Jul 31 12:02 bcm8483.bin

-rw-r--r-- 1 root root 541184 Jul 31 12:02 t4fw-1.15.37.0.bin
lrwxrwxrwx 1 root root     18 Jul 31 12:02 t4fw.bin -> t4fw-1.15.37.0.bin
-rw-r--r-- 1 root root 593920 Jul 31 12:02 t5fw-1.14.4.0.bin
-rw-r--r-- 1 root root 596992 Jul 31 12:02 t5fw-1.15.37.0.bin
lrwxrwxrwx 1 root root     18 Jul 31 12:02 t5fw.bin -> t5fw-1.15.37.0.bin
which is what the testing version of linux-firmware gives me.
Its worth trying a firmware update.

I would not expect to load drivers for functions I wasn't going to use but there is a lot of poorly designed hardware out there, so I wouldn't rule it out either.
