#define quoting(Roger Hardiman) // Hi, // I've got some strange results when hard coding IRQs for my PCMCIA cards. // // I have two PCMCIA modem cards, both the same make and they // emulate a standard serial port. // // I tried Hard Coding the IRQs in pccard.conf, // card "Nokia Mobile Phones" "DTP-2 ver II" // config 0x20 "sio2" 10 // config 0x20 "sio3" 11 // // and I compiled the kernel with SIO2 set to IRQ10 and SIO3 to IRQ11. // This worked on 2.2.5+PAO but on 3.0-RELEASE, sio2 worked fine // and sio3 worked but was "really slow" (like the IRQ was wrong). // // Changing to // card "Nokia Mobile Phones" "DTP-2 ver II" // config 0x20 "sio2" ? // config 0x20 "sio3" ? // and allowing the pccard software in 3.0-R to tell the sio driver // the 'actual irqs' fixed everything. // // My question then is, why can I not hard code the IRQ. Take a look at the output of pccardc dumpcis, and verify which are the valid interrupts for config 0x20. Maybe irq 11 is not a valid one. You cannot chose irqs on the fly if the card does not support them. Jonny -- Joao Carlos Mendes Luis M.Sc.
