tosh1800-smcinit - initialize the IrDA controler on Toshiba laptops SYNOPSIS
tosh1800-smcinit [OPTION] DESCRIPTION
IrDA configurator for laptops with ALI1533 bridge (LPC47N227 SuperIO), smc-ircc and not initializing BIOS (tested on Toshiba Satellite 1800-514, Toshiba Satellite 5100 and Toshiba Tecra 9100) to be used with Linux kernel. Toshiba Satellite 1800 laptops are provided with a SMCS LPC47N227 SuperIO chip which is IrDA SIR/FIR capable. The chip is connected through an ALI1533 PCI-ISA bridge. The IrDA subsystem of the SuperIO chip is supported by the smc-ircc Linux kernel module. Unfortunately the BIOS neither configurates the SuperIO chip IrDA subsystem (SIR port, FIR port, dma, irq, IrDA mode, power) nor sets the PCI-ISA bridge to decode any usable port. Linux kernel is thus prevented to detect the second UART making impossible to use it in SIR mode. For the same reason, the FIR mode smc-ircc is able to detect the SuperIO chip but, once found the IrDA subsystem unconfigured, fails to install. tosh1800-smcinit sets SIR and FIR ioport addresses, DMA and IRQ of the SuperIO chip IrDA subsystem then powers on the second UART. It also configures the PCI-ISA bridge to decode SIR and FIR ports. All this configuration work should be rather done into the kernel but it was more practical and safe to make a small testing tool of it. It can be probably extended to include configuration kludges for other similar SuperIO and ISA bridge combination. Testing was carried on a Toshiba Satellite 1800-514 with Linux kernel 2.4.17. I hope this work could be helpful, it was quite funny to do it however. OPTIONS

SMCINIT(8) Linux IrDA SMCINIT(8) NAME
smcinit - initialize the SMSC IrDA controler on various laptops SYNOPSIS
smcinit [OPTIONS] DESCRIPTION
Toshiba Satellite 1800, Satellite 5100, Tecra 9100 laptops and may be many other models are provided with a SMCS LPC47N227 SuperIO chip which is IrDA SIR/FIR capable. The IrDA subsystem of the SuperIO chip is supported by the smc-ircc Linux kernel module. Unfortunately the BIOS neither configurates the SuperIO chip IrDA subsystem (SIR port, FIR port, dma, irq, IrDA mode, power) nor sets the PCI-ISA bridge to decode any usable port. Linux kernel is thus prevented to detect the second UART making impossible to use it in SIR mode. For the same reason, the FIR mode smc-ircc is able to detect the SuperIO chip but, once found the IrDA subsystem unconfigured, fails to install. While this problem will be fixed in Linux 2.6.x kernel series, the 2.4.x users are frustrated. Daniele Peri, Rob Miller and Paul Hampson mananged to build little utilities that initialize the LPC47N227 SuperIO allowing smc-ircc IrDA kernel driver to detect and use the SMSC chip. My sole work was to put these utilities as one package, easy to install and use. OPTIONS
-V, --version Show program version and exit -h, --help Show a little help on options and exit -v, --verbose Increase the details about actions performed -t, --tty=device If specified, the serial device will be unbound from the kernel stock serial driver. It is there to replace an external call to setse- rial(1) to unset the UART of the device. There is no default value. -s, --sirio=IO Set the SIR (serial infrared) I/O port address to IO. Default value is 0x3f8. -f, --firio=IO Set the FIR (fast infrared) I/O port address to IO. Default value is 0x130. -i, --firirq=IRQ Set the FIR (fast infrared) IRQ line to IRQ. Default value is 3. -d, --firdma=DMA Set the FIR (fast infrared) DMA channel to DMA. Default value is 3. CONFIGURATION
When system startup a script is run from /etc/init.d and which run appropriate SMC intialization utility. This is done before PCMCIA startup because on Tecra 9100 and other models the orinoco_cs wireless driver will block the I/O region used 47N227 SuperIO. The only configuration file is /etc/sysconfig/smcinit and the variable SMCCONFIG can be set to "1800" or "5100". By default "5100" value is used. 1800 for Toshiba Satellite 1800 5100 for Toshiba Satellite 5100 and Toshiba Tecra 9100 The next step is to configure the kernel IrDA stack package to attach the smc-ircc driver. This is Linux distribution specific. The main thing is that the device should be set to "irda0". Run the following command: irattach irda0 -s Distribution specific configuration: SuSE Edit the /etc/sysconfig/irda and set IRDA_PORT=irda0 RedHat Edit the /etc/sysconfig/irda and set DEVICE=irda0 NOTES
The smc-ircc driver is preloaded in kernel. I tested the package only on Tecra 9100 without any additional step, but for Toshiba Satellite 1800 Daniele Peri sugest to put the following line in your /etc/modules.conf (on one line): options smc-ircc ircc_dma=3 ircc_irq=7 ircc_cfg=0x2e ircc_sir=0x2e8 ircc_fir=0x2f8 After that run the command: prompt# depmod -a If the laptop enter suspend mode, then resume operation the smc-ircc driver will stop working. You need to stop IrDA service, then SMCINIT, start SMCINIT, and finally start IrDA service. Simply put, the kernel driver must be unloaded, then reloaded. FILES
/etc/sysconfig/smcinit Configuration file for SMCINIT startup script. It's shell script. AUTHOR
