rsrcdb_query

Display database entries for PCI-related resources

Syntax:

rsrcdb_query [-i a|f|u] [-m a|f|u] [-p pool_id] [-v[v...]]

Runs on:

QNX Neutrino

Options:

-i a|f|u

Display PCI interrupt information:

a — display all PCI interrupts (i.e., the database contents)
f — display free (unallocated) interrupts
u — display used (allocated) interrupts

-m a|f|u

Display PCI address space information:

a — display all PCI address spaces (i.e., the database contents)
f — display free (unallocated) address spaces
u — display used (allocated) address spaces

-p pool_id

Display information for the specified pool of resources. Valid pool IDs are from 0 (the default pool) to 99; if the ID is unspecified or invalid, information for all existing pools is displayed.

-v[v...]

Cumulatively increase the verbosity of displayed detail.

Description:

The rsrcdb_query utility displays resource database entries for PCI-related resources, namely available address spaces and vectors for MSI/MSI-X interrupts. This information is populated by the hardware-dependent module and is what's used to allocate address space and interrupts to devices during configuration.

Note: You must specify at least one of -i and -m.

Examples:

Here's some sample output from rsrcdb_query -ma:
