ACPI support for bhyve. The -A option will create the minimal set of required ACPI tables in guest memory. Since ACPI mandates an IOAPIC, the -I option must also be used. Template ASL files are created, and then passed to the iasl compiler to generate AML files. These are then loaded into guest physical mem. In support of this, the ACPI PM timer is implemented, in 32-bit mode. Tested on 7.4/8.*/9.*/10-CURRENT. Reviewed by: neel Obtained from: NetApp Discussed with: jhb (a long while back)

* 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.

Add SMBIOS support. A new option, -U, can be used to set the UUID in the System Information (Type 1) structure. Manpage fix to follow. Approved by: grehan (co-mentor)

Support PCI extended config space in bhyve. Add the ACPI MCFG table to advertise the extended config memory window. Introduce a new flag MEM_F_IMMUTABLE for memory ranges that cannot be deleted or moved in the guest's address space. The PCI extended config space is an example of an immutable memory range. Add emulation for the "movzw" instruction. This instruction is used by FreeBSD to read a 16-bit extended config space register.

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.

Add HPET device emulation to bhyve. bhyve supports a single timer block with 8 timers. The timers are all 32-bit and capable of being operated in periodic mode. All timers support interrupt delivery using MSI. Timers 0 and 1 also support legacy interrupt routing. At the moment the timers are not connected to any ioapic pins but that will be addressed in a subsequent commit.

Add HPET device emulation to bhyve. bhyve supports a single timer block with 8 timers. The timers are all 32-bit and capable of being operated in periodic mode. All timers support interrupt delivery using MSI. Timers 0 and 1 also support legacy interrupt routing. At the moment the timers are not connected to any ioapic pins but that will be addressed in a subsequent commit. This change is based on a patch from Tycho Nightingale (tycho.nightingale@pluribusnetworks.com).

Add support for level triggered interrupt pins on the vioapic. Prior to this commit level triggered interrupts would work as long as the pin was not shared among multiple interrupt sources. The vlapic now keeps track of level triggered interrupts in the trigger mode register and will forward the EOI for a level triggered interrupt to the vioapic. The vioapic in turn uses the EOI to sample the level on the pin and re-inject the vector if the pin is still asserted. The vhpet is the first consumer of level triggered interrupts and advertises that it can generate interrupts on pins 20 through 23 of the vioapic. Discussed with: grehan@

Template ASL files are created, and then passed to the iasl compiler to generate AML files. These are then loaded into guest physical mem.

Extend the ACPI power management support to wire a virtual power button up to SIGTERM when ACPI is enabled. Sending SIGTERM to the hypervisor when an ACPI-aware OS is running will now trigger a soft-off allowing for a graceful shutdown of the guest. - Move constants for ACPI-related registers to acpi.h. - Implement an SMI_CMD register with commands to enable and disable ACPI. Currently the only change when ACPI is enabled is to enable the virtual power button via SIGTERM. - Implement a fixed-feature power button when ACPI is enabled by asserting PWRBTN_STS in PM1_EVT when SIGTERM is received. - Add support for EVFILT_SIGNAL events to mevent. - Implement support for the ACPI system command interrupt (SCI) and assert it when needed based on the values in PM1_EVT. Mark the SCI as active-low and level triggered in the MADT and MP Table. - Mark PCI interrupts in the MP Table as active-low in addition to level triggered. Reviewed by: neel

Add HPET device emulation to bhyve. bhyve supports a single timer block with 8 timers. The timers are all 32-bit and capable of being operated in periodic mode. All timers support interrupt delivery using MSI. Timers 0 and 1 also support legacy interrupt routing. At the moment the timers are not connected to any ioapic pins but that will be addressed in a subsequent commit. This change is based on a patch from Tycho Nightingale (tycho.nightingale@pluribusnetworks.com).

When a PCI INTx interrupt is asserted, ensure that both pins are asserted. - Provide an initial routing of PCI interrupt router (PIRQ) pins to 8259A pins (ISA IRQs) and initialize the interrupt line config register for the corresponding PCI function with the ISA IRQ as this matches existing hardware. - Add a global _PIC method for OSPM to select the desired interrupt routing configuration. - Update the _PRT methods for PCI bridges to provide both APIC and legacy PRT tables and return the appropriate table based on the configured routing configuration. Note that if the lpc device is not configured, no routing information is provided. - When the lpc device is enabled, provide ACPI PCI link devices corresponding to each PIRQ pin. - Add a VMM ioctl to adjust the trigger mode (edge vs level) for 8259A pins via the ELCR. - Mark the power management SCI as level triggered. - Don't hardcode the number of elements in Packages in the source for the DSDT. iasl(8) will fill in the actual number of elements, and this makes it simpler to generate a Package with a variable number of elements.

Allow PCI devices to be configured on all valid bus numbers from 0 to 255. This is done by representing each bus as root PCI device in ACPI. The device implements the _BBN method to return the PCI bus number to the guest OS. Each PCI bus keeps track of the resources that is decodes for devices configured on the bus: i/o, mmio (32-bit) and mmio (64-bit). These windows are advertised to the guest via the _CRS object of the root device. Bus 0 is treated specially since it consumes the I/O ports to access the PCI config space [0xcf8-0xcff]. It also decodes the legacy I/O ports that are consumed by devices on the LPC bus. For this reason the LPC bridge can be configured only on bus 0. The bus number can be specified using the following command line option to bhyve(8): "-s <bus>:<slot>:<func>,<emul>[,<config>]" Discussed with: grehan@ Reviewed by: jhb@

Simplify the assignment of memory to virtual machines by requiring a single command line option "-m <memsize in MB>" to specify the memory size. Prior to this change the user needed to explicitly specify the amount of memory allocated below 4G (-m <lowmem>) and the amount above 4G (-M <highmem>). The "-M" option is no longer supported by 'bhyveload' and 'bhyve'. The start of the PCI hole is fixed at 3GB and cannot be directly changed using command line options. However it is still possible to change this in special circumstances via the 'vm_set_lowmem_limit()' API provided by libvmmapi.
