Hi all,
I have problem with a http://www.lavalink.com/dev/index.php?id=53
net5501 identifies it like this from the BIOS:
Slot Vend Dev ClassRev Cmd Stat CL LT HT Base1 Base2 Int
-------------------------------------------------------------------
0:14:0 1407 0110 07000200 0041 0480 00 00 80 0000E501 00000000 10
0:14:1 1407 0111 07000200 0041 0480 00 00 80 0000E509 00000000 10
A linux 2.6.27 kernel identify this card like this a boot:
Serial: 8250/16550 driver8 ports, IRQ sharing enabled
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
0000:00:0e.0: ttyS4 at I/O 0xe500 (irq = 10) is a 16550A
0000:00:0e.1: ttyS5 at I/O 0xe508 (irq = 10) is a 16550A
lspci -v gives:
00:0e.0 Serial controller: Lava Computer mfg Inc Lava DSerial-PCI Port A
(prog-if 02 [16550])
Subsystem: Lava Computer mfg Inc Lava DSerial-PCI Port A
Flags: slow devsel, IRQ 10
I/O ports at e500 [size=8]
Kernel driver in use: serial
00:0e.1 Serial controller: Lava Computer mfg Inc Lava DSerial-PCI Port B
(prog-if 02 [16550])
Subsystem: Lava Computer mfg Inc Lava DSerial-PCI Port B
Flags: slow devsel, IRQ 10
I/O ports at e508 [size=8]
Kernel driver in use: serial
I tried to use both /dev/ttyS4 and /dev/ttyS5 without any problem.
FreeBSD 7.3 identify the card like this at boot:
sio0: <Koutech IOFLEX-2S PCI Dual Port Serial> port 0xe500-0xe507 irq 10 at
device 14.0 on pci0
sio0: moving to sio4
sio4: type 16550A
sio4: [FILTER]
sio0: <Koutech IOFLEX-2S PCI Dual Port Serial> port 0xe508-0xe50f irq 10 at
device 14.1 on pci0
sio0: moving to sio5
sio5: type 16550A
Now to the problem...
With FreeBSD the system halt when I run sysinstall.
If I try to use the serial ports; sio4 seems to work, but when I try to open
sio5 the system halt.
I think this is where FreeBSD gets "Koutech" info instead of "Lava" from...
/usr/src/sys/dev/sio/sio_pci.c
{ 0x01101407, "Koutech IOFLEX-2S PCI Dual Port Serial", 0x10 },
{ 0x01111407, "Koutech IOFLEX-2S PCI Dual Port Serial", 0x10 },
/usr/src/sys/dev/puc/pucdata.c lists some serial cards from Lava, but not the
one I have. I can't find any description of what the purpose of the different
fields in the structure is.
Does anyone have some ideas of what to try to get this card work properly in
FreeBSD (7.3)?
Also, what does it mean that the BIOS says "Base1" is 0xe501 and 0xe509 while
both linux and FreeBSD reports the address to be 0xe500 and 0xe508, it looks
like it is an offset of 1.
Thanks,
Göran
