Friday April 14, 2006 Equivalent of 'cat /proc/interrupts'
New MDB dcmd ::interrupts
Solaris Express now has support for a new MDB dcmd ::interrupts
that shows similar output to that of 'cat /proc/interrupts' on Linux.
Output of ::interrupts on a x64 running 64-bit Solaris Express:
(System is using IOAPIC)

Driver name is represented as <driver_name><instance#>
and Type shows where Fixed (legacy) or MSI interrupts are being used.
IPI interrupt type indicates xcalls.
The Share column shows if the interrupt is being shared and by how many.
On a uppc(7d) based system, the sample output is shown here

On a Niagara based SunFire T2000, the output looks like this:

On a SunFire V890, (which does not support MSI interrupts, the ouput looks like this:
