2012-06-19Add PIIX4 properties to control PM system states.Gleb Natapov1-2/+2
This patch adds two things. First it allows QEMU to distinguish between regular powerdown and S4 powerdown. Later separate QMP notification will be added for S4 powerdown. Second it allows S3/S4 states to be disabled from QEMU command line. Some guests known to be broken with regards to power management, but allow to use it anyway. Using new properties management will be able to disable S3/S4 for such guests. Supported system state are passed to a firmware using new fw_cfg file. The file contains 6 byte array. Each byte represents one system state. If byte at offset X has its MSB set it means that system state X is supported and to enter it guest should use the value from lowest 3 bits.

2012-02-24suspend: switch acpi s3 to new infrastructure.Gerd Hoffmann1-2/+1
This patch switches pc s3 suspend over to the new infrastructure. The cmos_s3 qemu_irq is killed, the new notifier is used instead. The xen hack goes away with that too, the hypercall can simply be done in a notifier function now. This patch also makes the guest actually stay suspended instead of leaving suspend instantly, so it is useful for more than just testing whenever the suspend/resume cycle actually works.

2012-01-19kvm: x86: Add user space part for in-kernel i8259Jan Kiszka1-0/+1
Introduce the alternative 'kvm-i8259' device model that exploits KVM in-kernel acceleration. The PIIX3 initialization code is furthermore extended by KVM specific IRQ route setup. GSI injection differs in KVM mode from the user space model. As we can dispatch ISA-range IRQs to both IOAPIC and PIC inside the kernel, we do not need to inject them separately. This is reflected by a KVM-specific GSI handler. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

2011-10-21pc: Fix floppy drives with if=noneKevin Wolf1-1/+2
Commit 63ffb564 broke floppy devices specified on the command line like -drive file=...,if=none,id=floppy -global isa-fdc.driveA=floppy because it relies on drive_get() which works only with -fda/-drive if=floppy. This patch resembles what we're already doing for IDE, i.e. remember the floppy device that was created and use that to extract the BlockDriverStates where needed.

2011-10-16i8259: Eliminate PicState2Jan Kiszka1-4/+4
Introduce a reference to the slave PIC for the few cases we need to access it without a proper pointer at hand and drop PicState2.

2011-10-16i8259: PREP: Replace pic_intack_read with pic_read_irqJan Kiszka1-1/+0
There is nothing in the i8259 spec that justifies the special pic_intack_read. At least the Linux PREP kernels configure the PICs properly so that pic_read_irq returns identical values, and setting read_reg_select in PIC0 cannot be derived from any special i8259 mode. So switch ppc_prep to pic_read_irq and drop the now unused PIC code.

2011-10-16pc: Fix and clean up PIC-to-APIC IRQ pathJan Kiszka1-1/+1
The master PIC is connected to the LINTIN0 of the APICs. As the APIC currently does not track the state of that line, we have to ask the PIC to reinject its IRQ after the CPU picked up an event from the APIC. This introduces pic_get_output to read the master PIC IRQ line state without changing it. The APIC uses this function to decide if a PIC IRQ should be reinjected on apic_update_irq. This reflects better how the real hardware works. The patch fixes some failures of the kvm unit tests apic and eventinj by allowing to enable the proper CPU IRQ deassertion when the guest masks some pending IRQs at PIC level.

2011-09-23pc: Unbreak ROM mapping for ISA machineJan Kiszka1-1/+1
This is based on the original fix by Hervé Poussineau: pc_memory_init actually takes a memory region for mapping BIOS and extension ROMs. That equals the PCI memory region if PCI is available, but must be system memory in the ISA case.

2011-08-22440fx: fix PAM, PCI holesAvi Kivity1-3/+10
The current implementation of PAM and the PCI holes is broken in several ways: - PCI BARs are not restricted to the PCI hole (a BAR may hide memory) - PCI devices do not respect PAM (if a PCI device maps a region while PAM maps the region to RAM, the request will be honored) This patch fixes things by introducing a pci address space, and using memory region aliases to represent PAM regions, SMRAM, and PCI holes. The memory hierarchy looks something like system_memory | +--- low memory alias (0-0xe0000000) | | | +-- ram@0 | +--- high memory alias (0x100000000-EOM) | | | +-- ram@0xe0000000 | +--- pci hole alias (end of low memory-0x100000000) | | | +-- pci@end-of-low-memory | | +--- pam[n] (0xc0000-0xc3fff etc) (when set to pci, priority 1) | | | +-- pci@0xc4000 etc | +--- smram (0xa0000-0xbffff) (when set to pci/vga, priority 1) | +-- pci@0xa0000 etc ram (simple ram region) pci | +--- BARn | +--- VGA 0xa0000-0xbffff | +--- ROMs Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
