[Linux-ia64] rx2600 console output with management card

[Linux-ia64] rx2600 console output with management card

[Ian Wienand]

Hello,

Does anyone know if there is some trick to getting linux console
output through the management processor on the rx2600?  all the
documentation states that the management card processor output mirrors
the system console when not it it's managment mode -- which it does
until linux starts.

linux console works fine when plugged into the 'normal' serial port
(which is labeled 'console'), but when plugged into the console output
of the management card (via the provided splitter) I see none of
linux's output.  same problem via telnet -- everything stops when efi
stops.

our hp support guy said he thinks hpux uses special /dev entries to
output via the management card, i couldn't verify this.

some extra info :

we boot with console=ttyS0

From the EFI boot maintenance menu I have
* Acpi(PNP0501,0)/Uart(9600 N81)/VenMsg(Vt100)
* Acpi(HWP0002,700)/Pci(1|1)/Uart(9600 N81)/VenMsg(Vt100)
* Acpi(HWP0002,700)/Pci(2|0)
selected as output/input/error devices.

from .config

# Serial drivers

CONFIG_SERIAL_8250=y
# CONFIG_SERIAL_8250_ACPI is not set
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_8250_HCDP=y
# CONFIG_SERIAL_8250_EXTENDED is not set

any suggestions appreciated!

Which version of firmware do you have installed? When I upgraded the
System and BMC firmware to 1.05 (System = 1.82, BMC = 1.40) I suddenly
got the same behavior.

Before the upgrade I had ttyS0 through the management processor,
afterwards, however, I have the following mapping:

console/serial A:       ttyS0
serial B:               ttyS1
console/MP:             ttyS3   (same as through the mangagement lan)
remote/MP:              -----
ups/MP:                 ttyS2

I would like to get the old behaviour back too.

Yes, there's a trick ;-(  Here's how it works:

There's three methods for finding serial ports that apply to rx2600
w/ECI card.  First, we parse the HCDP table.  Second, we search the ACPI
namespace for serial ports.  Third, we walk the PCI busses looking for
serial ports.

The two built-in serial ports are in the ACPI namespace, the ECI card
actually contains a PCI bus where we find the serial ports.  Firmware
determines which port is listed in the HCDP table according to which
Console Input & Console Output devices were listed first.  Unfortunately,
you can't tell which one was selected first, so the safe thing to do is
make sure only one is listed.

Yes, after upgrading your firmware, you have to restore your ConIn/ConOut
to sane values.

Mmm.. not exactly.  In the instance you quote here, ttyS3 would be
the mirrored port.  ttyS4 and ttyS5 are the local and remote sessions
respectively.

Of course, it should be:

ttyS0		mirrored console
ttyS1		serial A
ttyS2		serial B
ttyS3		UPS
ttyS4		local session
ttyS5		remote session

once you fix your ConIn/ConOut settings.

Yup, when only:

Acpi(HWP0002,700)/Pci(1|1)/Uart(9600 N81)/VenMsg(Vt100+)

is listed as output then everything works as it should. Pity I can't
have both the serial port and the on on the ECI card listed :-(

Thanks for your help!
