OPAL_HANDLE_INTERRUPTΒΆ
The host OS must pass all interrupts in the opal-interrupts property of ibm,opal in the device tree to OPAL.
An example dt snippet is:
ibm,opal {
opal-interrupts = <0x10 0x11 0x12 0x13 0x14 0x20010 0x20011 0x20012 0x20013 0x20014 0xffe 0xfff 0x17fe 0x17ff 0x2ffe 0x2fff 0x37fe 0x37ff 0x20ffe 0x20fff 0x217fe 0x217ff 0x22ffe 0x22fff 0x237fe 0x237ff>;
};
When the host OS gets any of these interrupts, it must call
OPAL_HANDLE_INTERRUPT
.
The OPAL_HANDLE_INTERRUPT
call takes two parameters, one input and one output.
uint32_t isn
the interrupt
uint64_t *outstanding_event_mask
returns outstanding events for host OS to handle
The host OS should then handle any outstanding events.
See OPAL_POLL_EVENTS for documentation on events.
