Dang. I found out that the chip (SMC LPC47N252) works in both SIR and FIR mode with the RedHat 8.0 2.4.18-24.8.0 kernel, while it refuses to work in both 2.4.21-pre4 and 2.5 (up to .62 at least).
What I try to do:
modprobe irda modprobe ircomm modprobe smc-ircc irattach irda0 -s 1
Reason why it doesn't work ? Well - SIR: no idea. The most I've been able to squeeze is a line from irdadump every 10 seconds (instead of a line every second or less in "normal" behavior). FIR: smc-ircc says chip reports irq 0.
Relevant IrDA .config stuff, from my 2.4.21-pre4:
[asuardi@incident linux]$ egrep 'IRDA|SIR|FIR' .config CONFIG_IRDA=m # CONFIG_IRDA_ULTRA is not set CONFIG_IRDA_CACHE_LAST_LSAP=y CONFIG_IRDA_FAST_RR=y CONFIG_IRDA_DEBUG=y CONFIG_IRTTY_SIR=m CONFIG_IRPORT_SIR=m # CONFIG_USB_IRDA is not set # CONFIG_NSC_FIR is not set # CONFIG_WINBOND_FIR is not set # CONFIG_TOSHIBA_FIR is not set CONFIG_SMC_IRCC_FIR=m # CONFIG_ALI_FIR is not set # CONFIG_VLSI_FIR is not set
This same .config worked fine for the SMC chip on my older Latitude (though the chip model was different).
Will keep digging... but in case anyone has tips, please let me know :)
