Reserve IRQ/Interrupt exclusively for one device
by lambo69 from LinuxQuestions.org on (#6DFTR)
Hi all,
Code:# cat /proc/interrupts |grep hdspshows
Code: 18: 0 257590 0 0 IO-APIC 18-fasteoi i801_smbus, snd_hdsphow can i manage it, to have snd_hdsp exlusively using one interrupt? All i found was distributing interrupts on processors (irqthreads, irqbalance, affinity), but nothing about how to have an irq reserved for only one device.
Thanks in advance
