Modify APIC interrupts priorities
September 12, 2009 10:40PM
Hello,

My PC104 (PentiumM) is connected to a customized PCI hardware.
The hardware creates PCI interrupts every ~2ms.
When the e100 (NIC) and\or the ATA controller are working, sometimes
I'm not getting an interrupt from the customized hardware.
Is it possible to modify the APIC driver in order to resolve this issue ?
It is required that the CPU will stop handling another interrupt (e.g e100) and
handle my interrupt (which is very fast).
The interrupt from the customized hardware is much more important than the e100 and other PCI devices.

Thanks.
