2013-05-15Cache boot-fail-wait to avoid romfile access after POST.rel-1.7.2.21.7.2-stableKevin O'Connor1-6/+9
Memory allocated with malloc_tmp() can't be used after the POST phase. So, access boot-fail-wait in post phase and store it for the boot phase to use. This fixes the regression introduced by commit 59d6ca52.

2013-05-15virtio-scsi: Set _DRIVER_OK flag before scsi target scanningAsias He1-2/+3
Before we start scsi target scanning, we need to set the VIRTIO_CONFIG_S_DRIVER_OK flag so the device can do setup properly. This fix a bug when booting tcm_vhost with seabios.

Device needs the exact size of these data structure. Prevent padding. This fixes guest hang when booting seabios + tcm_vhost. Signed-off-by: Asias He <asias@redhat.com> (cherry picked from commit b44a7be17bdd270ea029a8e2ec0c2e80c6cd0444)
2013-02-24seabios: Add a dummy PCI slot to irq mapping functionrel-1.7.2.1Alex Williamson1-1/+9
This should never get called, but if we somehow get a new chipset that fails to implement their own pci_slot_get_irq function, fail gracefully and add a debug log message. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2013-02-24seabios q35: Add new PCI slot to irq routing functionAlex Williamson1-1/+32
q35/ich9 doesn't use the same interrupt mapping function as i440fx/piix. PIRQA:D and PIRQE:H are programmed identically, but we start at index 0, not index -1. Slots 25 through 31 are also programmed independently. When running qemu w/o this patch, a device at address 0:6.0 will have its PCI interrupt line register programmed with irq 10 (as seen by info pci), but it actually uses irq 11 (as reported the guest). Half of the interrupt lines are misprogrammedi like this. Functionally, a fully emulated qemu guest doesn't care much, but when we try to use device assignment, we really need to know the correct irqs. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2013-02-24seabios q35: Enable all PIRQn IRQs at startupAlex Williamson1-4/+2
We seem to use the IRQEN bit of the PIRQn registers interchangeably to select APIC mode or to disable an IRQ. I can't decide if we're intending to disable the IRQ or select APIC mode here, but in either case it prevents PIC mode assigned devices from working. When seabios writes IRQEN to these registers, qemu interprets that as APIC mode, so while the boot ROM driver is waiting for an interrupt on ISA compatible IRQ 10 or 11, KVM is injecting interrupts to APIC pins 16 - 23. Devices on the root bus use PIRQE:H while the root ports use PIRQA:D. Enable them all so we don't limit where we support boot ROMs. The guest will later disable unused IRQs with the ACPI _DIS method.

2013-02-24Verify CC is valid during build tests.Kevin O'Connor1-1/+8
Update test-build.sh to report if it can't run the c compiler at all. Without this test, a totally non-working build environment will yield an "invalid LD" message which can be confusing. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

2013-01-12vgabios: implement AX=1120H..1124H functionsrel-1.7.2Paolo Bonzini1-0/+60
These function only have to set INT 1Fh and INT 43h, and set the BDA height + number of rows. I could not find out whether AX=1120h should also set the character height to 8. I think not, because INT 43h might still point to 14- or 16-pixel high characters and in this case INT 1Fh will not be used at all. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-01-12boot: Support "halt" in the boot order to prevent default boot attempts.Kevin O'Connor1-0/+8
Current seabios will attempt to boot from both configured devices and a list of default devices. Sometimes it is desirable to only attempt to boot from the configured devices and not from any of the default devices. This patch adds support for a "HALT" item in the "bootorder" file - its presence will prevent SeaBIOS from attempting any default boot actions.

2012-12-15acpi: reintroduce LNKSPaolo Bonzini1-1/+17
Commit 4540409 (acpi: LNKS is not needed, 2012-08-07) removed LNKS because it basically worked by chance: _CRS returns something else then one of the possible resources from _PRS, _DIS would not really disable the interrupt, and there was no _SRS method. It just happened to work because all OSes have some kind of special-casing for SCI. Unfortunately, the code after the patch is also against the spec, and it breaks FreeBSD because it treats IRQ 9 polarity as active low without the Interrupt() entry. Actually, numeric _PRT entries are handled the same in Linux and FreeBSD (as active-low). However, under Linux it just happens to trigger another special casing of SCI which sets SCI up from its override entry in the MADT, ignoring the DSDT completely. This patch adds back the LNKS, but without using the PIIX register for LNKA in its methods. Tested-by: Luigi Rizzo <rizzo@iet.unipi.it> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-12-11Add compile checking phase to build.Kevin O'Connor1-4/+8
The build textually includes all the code together in one unit for the compiler in order to use gcc's -fwhole-program option. Textually including all the code can mask subtle code errors (eg, forgetting to include the correct headers) and can lead to confusing error reports from the compiler. So, compile each file individually in addition to the normal textually inclusive build. This improves the error checking while still obtaining the benefits of -fwhole-program.

2012-12-11Don't use gcc's -combine option.Kevin O'Connor2-61/+6

2012-12-02acpi: PCI routing DSDT simplifications.Kevin O'Connor2-125/+98
Use define_link() macro in PIIX4 hardware definitions. Now that all remaining irq links are the same it's possible to just use a macro to define the link. Port several size optimizations to the q35 irq routing definitions: define the PRQx fields in the _SB scope to reduce size of register references, define CRS and STA methods in _SB scope to reduce code duplication, simplify acpi code.
