New Revision: 39124
Changeset: http://dev.haiku-os.org/changeset/39124
Modified:
haiku/trunk/src/add-ons/kernel/bus_managers/acpi/Jamfile
haiku/trunk/src/add-ons/kernel/bus_managers/acpi/acpi_busman.c
Log:
Added kernel setting to dump MADT to syslog. It's very useful for understanding
interrupt configuration.
It needs a bit polish in code but wanted to commit before leaving BG.
