[tlinux-users:02215] IrDA on Satellite Pro 6000
05/21/2002
Hi,

I am currently trying to get the IrDA stuff working in my SatellitePro
6000, but with no success so far.

I already read, that it's some SMC hardware contained in the PCI-to-ISA
bridge (M1533) of the ALi chipset. Which makes me wondern, if I should
go for the ali-ircc or smc-ircc module of my current 2.4.19-pre7 kernel.

But I think, before I try to load a module, findchip (part of the
irda-common package in Debian Woody) should mention the related
hardware.

According to
http://www.pasta.cs.uit.no/pipermail/linux-irda/2001-October/003262.html
there is the problem of activating the SMC chip first. The tools setpci
and setsmc haven't changed the behaviour on my SatellitePro 6000.
On the other hand it's quite unlikely, that setpci/setsmc written for a
SP4600 will also work on a SP6000, even if the IrDA-component seems to
be identical.

Any ideas about further approaches to this problem?

Hi,

I solved the problem in the meanwhile:
- The SMC hardware is using dma=1, irq=10, firbase=0x130, sirbase=0x2e8.

- Use Daniele Peri's tool to activate the IrDA stuff, which is not done
automatically by the BIOS:

http://www.csai.unipa.it/peri/toshsat1800-irdasetup/

I am using a pre-install entry in my modules.conf:
options smc-ircc ircc_dma=1 ircc_irq=10 ircc_sir=0x2e8 ircc_fir=0x130
pre-install smc-ircc /usr/local/bin/toshsat1800-irdasetup --dma=1 --irq=10 -
-firbase=0x130 --sirbase=0x2e8

- Take care to exclude the ioports for smc-ircc in the pcmcia
configuration (file /etc/pcmcia/config.opts on my Debian Woody box):
exclude port 0x130-0x137, port 0x2e8-0x2ef
In my case the 0x130 port would otherwise be used by orinoco_cs.
