x86 ISA bus device driver interrupts

x86 ISA bus device driver interrupts

Post by Gary L. Schap » Sat, 23 Sep 1995 04:00:00

Anyone know why my device driver breaks when I change
it's driver.conf file to read "intr=15,3" instead of
"intr=3,15" (which works)?  The device is hardware
jumpered to use IRQ 15.


1. x86 device drivers and PCI interrupt

I am writing a x86 device driver for a PCI device. I am now trying
to catch the interrupt which appear on interrupt line 'C' on the
PCI bus.

The problem is, I do not know which IRQ the interrupt is routed to.
There is probably an interrupt router somewhere inside the PC (a
DEC celebris XL/90), but I do not know how to reveal its secrets.

If anybody know something about this, I would be happy to know.

2. Limit the user accessing

3. SOLARIS x86 Isa card device driver.

4. Not detecting card...

5. Unsupported ISA device doesn't appear in /devices on Solaris x86

6. Multiple IP address per interface

7. user space device driver can't write to isa device

8. RedHat Linux 6.1

9. USB device has no driver in /proc/bus/usb/devices

10. < x86: upgrade from ISA to EISA bus (on installed system) >

11. How can I know kernel has received interrupt from ISA card and execute interrupt service routine?

12. Does Linux support >16 MB in Vl-bus or ISA bus now?

13. Driver for PC ISA bus Memory Window?
