tosh-smcinit
============
I've modified the tosh5100-smcinit.c to make it more flexible and renamed
it to tosh-smcinit.c because it works with several notebooks of Toshiba.
Please note that the names of the notebooks differ from country to
country. I used the German names, you can see them at http://www.toshiba.de
or http://newsletter.toshiba-tro.de/main (detailed hardware description)
In many newer notebooks, Toshiba changed the SuperIO chip. They use no
longer the LPC47N227, instead other chips are used like LPC47N24x. But we
are working on modify the smc-ircc driver and smcinit so this chips will
also work in the near future.
If you own an other notebook than a Toshiba, your model is not in my list below
and it use a newer chipset from Intel and the LPC47N2xx from SMSC, there are
good chances to get IrDA working. If you have MS Windows installed, please
send me your settings of the IrDA and I will include it. I need the IRQ, DMA
and the 2 I/O port settings. Please also attach a copy of your /proc/interrupts,
/proc/ioports and /proc/dma
tosh-smcinit needs 4 parameters to initalize the SMC chip:
SIR IOPort, FIR IOPort, FIR Interrupt and FIR DMA.
I tested the following models, use the parameter in the list:
Model SIR_IO FIR_IO FIR_IRQ FIR_DMA ID PCI-ID

(* = Compiled-In values, in this case, you don't need parameters)
Other values for the parameters are sometimes also possible, if you got
conflicts.
OK, to make it running, you have to do the following steps:
- Compile it.
- Run tosh-smcinit *before* you insert the "smc-ircc" kernel module.
For example you can do this in the /etc/modules.conf
Without parameters, "tosh-smcinit" give no output, but if you run
it as "tosh-smcinit -v", you will see if all should work.
With --sirio=0x03f8, --firio=0x130, --firirq=3 and --firdma=3 you can
set the parameters.
More detailed instructions are in README.Rob, just replace tosh5100-smcinit
with tosh-smcinit in his text. :)
If you use a PCMCIA or miniPCI slot (also built-in WLAN), on some machines
are conflicts at the I/O ports between IrDA and some cards. Sometimes it
helps if you change I/O port range, which "pcmcia-cs" uses. The line
include port 0x160-0x3f7, port 0x400-0x4ff, port 0x800-0x8ff, port 0xc00-0xcff
in /etc/pcmcia/config.opts regulates it.
Also IRQ-conflicts with other built-in components are possible. For example,
my Atheros AR5212 miniPCI-Card got the IRQ 3 assigned from the ACPI BIOS.
If you computer have a "classic" BIOS menu, look at the entry about the
PCI-IRQ Routing. If the computer is "legacy-free", there are good chances
to include the routing with the "acpi_irq_balance" and "acpi_irq_pci=n"
kernel parameters.
