Hi, Assuming I have a device driver in FreeBSD, how to make it visible during ACPI probe. For Eg: In sys/dev/uart -> I see uart_bus_acpi.c, which has the list of device which I believe, will be visible during ACPI probe(if it exists) Likewise, is there any generic framework to add the devices for ACPI probe for all types of devices (uart, i2c, gpio etc.,). What is the purpose of device list in sys/contrib/dev/acpica/common/ahids.c file? Also, Is there any good reading material for understanding the ACPI code design in FreeBSD? I see directories like sys/dev/acpi_support, sys/dev/acpica and sys/contrib/dev/acpica. So, any good read to understand how they are connected and placed in FreeBSD? Thanks, Rajesh.
