svn commit: r260206 - head/usr.sbin/bhyve

New Revision: 260206
URL: http://svnweb.freebsd.org/changeset/base/260206
Log:
Rework the DSDT generation code a bit to generate more accurate info about
LPC devices. Among other things, the LPC serial ports now appear as
ACPI devices.
- Move the info for the top-level PCI bus into the PCI emulation code and
add ResourceProducer entries for the memory ranges decoded by the bus
for memory BARs.
- Add a framework to allow each PCI emulation driver to optionally write
an entry into the DSDT under the \_SB_.PCI0 namespace. The LPC driver
uses this to write a node for the LPC bus (\_SB_.PCI0.ISA).
- Add a linker set to allow any LPC devices to write entries into the
DSDT below the LPC node.
- Move the existing DSDT block for the RTC to the RTC driver.
- Add DSDT nodes for the AT PIC, the 8254 ISA timer, and the LPC UART
devices.
- Add a "SuperIO" device under the LPC node to claim "system resources"
aling with a linker set to allow various drivers to add IO or memory
ranges that should be claimed as a system resource.
- Add system resource entries for the extended RTC IO range, the registers
used for ACPI power management, the ELCR, PCI interrupt routing register,
and post data register.
- Add various helper routines for generating DSDT entries.
