|
|
* bhyve ACPI table generator.
|
|
*
|
|
* Create the minimal set of ACPI tables required to boot FreeBSD (and
|
|
* hopefully other o/s's) by writing out ASL template files for each of
|
|
* the tables and the compiling them to AML with the Intel iasl compiler.
|
|
* The AML files are then read into guest memory.
|
|
*
|
|
* The tables are placed in the guest's ROM area just below 1MB physical,
|
|
* above the MPTable.
|
|
*
|
|
* Layout
|
|
* ------
|
|
* RSDP -> 0xf2400 (36 bytes fixed)
|
|
* RSDT -> 0xf2440 (36 bytes + 4*7 table addrs, 4 used)
|
|
* XSDT -> 0xf2480 (36 bytes + 8*7 table addrs, 4 used)
|
|
* MADT -> 0xf2500 (depends on #CPUs)
|
|
* FADT -> 0xf2600 (268 bytes)
|
|
* HPET -> 0xf2740 (56 bytes)
|
|
* MCFG -> 0xf2780 (60 bytes)
|
|
* FACS -> 0xf27C0 (64 bytes)
|
|
* DSDT -> 0xf2800 (variable - can go up to 0x100000)
