Sciclient_rmIaInst Struct Reference

Detailed Description

Interrupt aggregator instance containing data required to manage interrupt route discovery using an IA.

Parameters

dev_id	Device ID of NavSS IA
imap	IA subsystem's event interrupt mapping MMR region
sevt_offset	SEVI global event offset for IA
n_sevt	Number of IA SEVIs
n_vint	Number of IA virtual interrupts
vint_usage_count	Number of VINT status bits used for event mapping. The usage count for each VINT cannot exceed the number of maximum supported event mappings.
v0_b0_evt	A standalone element is needed to track usage of VINT 0 bit 0. The INTMAP registers are read to determine VINT bit usage. The default state for INTMAP registers is 0x0000 which translates to the INTMAP using VINT 0 bit 0. This field allows the IA driver to determine if VINT 0 bit 0 is truly mapped to an IA event.
rom_usage	IA event to VINT mappings used by ROM during boot that need to be reset to hardware reset values
n_rom_usage	Number of entries in the rom_usage array
