irq complication
hi,
i looked around already and had no luck finding anything.
Im trying ot install a wpc11v3 linksys wireless card, and i have been for about a week now.
Im near certain i have figured out my problem. When i plug in my card while knoppix is running, it crashes. When i plug it into the laptop and boot up, it loads the card and then crashes. Theres no way to run iwconfig or anything because my card crashes the system. I have to find a way to get the card to sit in the laptop without any crashing right. So im near certain it is a IRQ conflict between my PCI and another device. How can i configure my irq's running knoppix. knoppix is installed to my harddrive so i have no option to use any cheatcodes. everything i read pertains to cheatcodes and whatnot, and i have researched and i cant find any problems like this with IRQ's.
Im using a toshiba satellite 2540cds laptop. i checked the bios and there is no IRQ option in there. Also during hte boot option i see something lke irq error pci=irq something like that im not certain. I'll have to double check that.

Hi all,
I am a Linux newbie in kernel development. In class I was asked a question about IRQ distribution as followed.

Hello,
I have develop a driver for my hardware and now, I need to handle a IRQ but I does not work.
As I can understand, to handle a irq, it is necessary to make a request_irq(). If the return value is zero, ok, no problem to handle irq.
Here is a easy example of my driver:

AHA(4) BSD Kernel Interfaces Manual AHA(4)
NAME
aha -- Adaptec SCSI host adapter driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device scbus
device aha
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
aha_load="YES"
In /boot/device.hints:
hint.aha.0.at="isa"
DESCRIPTION
This driver provides access to the SCSI bus connected to the Adaptec AHA-154x and AHA-1640 SCSI host adapters. x is 0 for controllers with-
out a floppy drive and 2 for controllers that have them. For optimum performance, Adaptec AHA-174x controllers should be configured in
enhanced mode and attached via the ahb(4) driver.
One device hint entry for every card to be attached by the system is required. Specific values for the port address, IRQ, and DRQ may be
specified. If wildcard values are used, the driver will query the device for its current settings and use those. If the port address is a
wildcard, the driver consults an internal table of possible port address locations and attaches to the first unattached card it finds. The
possible port addresses for this card are 0x330, 0x334, 0x230, 0x234, 0x130, and 0x134.
The AHA-1640 is an MCA bus card. Since the MCA bus is a self-identifying bus, no setting of hints is required.
HARDWARE
The aha driver supports the following SCSI host adapters:
o Adaptec AHA-154xB
o Adaptec AHA-154xC
o Adaptec AHA-154xCF
o Adaptec AHA-154xCP
o Adaptec AHA-1640
o Adaptec AHA-174x in 154x emulation mode
o DTC 3290 SCSI controller in 1542 emulation mode
o Tekram SCSI controllers in 154x emulation mode
SEE ALSO
ahb(4), ahc(4), aic(4), cd(4), da(4), sa(4), scsi(4)
AUTHORS
The aha driver was ported by M. Warner Losh from the bt driver written by Justin T. Gibbs.
BUGS
The AHA-154xA card does not support residuals on data transfers. As a result, this card is no longer supported.
There have been some reports that the AHA-154xB does not work well under heavy load.
The AHA-154xCP is a plug and play controller. However, its resources are set using the on-board BIOS and cannot be moved. Failures to
attached for this card are often caused when the resources set in the BIOS conflict.
