TPM TIS for TPM 2 introduced the following extensions beyond the TPM TIS 1.3 (used for TPM 1.2): - A new 32bit interface Id register was introduced. - New flags for the status (STS) register were defined. - New flags for the capability flags were defined. Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2 on the backend side. Support the old TPM TIS 1.3 configuration if a TPM 1.2 is being used.

2015-05-31i386/pc_q35: don't insist on board FDC if there's no default floppyLaszlo Ersek1-2/+2
The "no_floppy = 1" machine class setting causes "default_floppy" in main() to become zero. Consequently, default_drive() will not call drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no default floppy drive will be created for the virtual machine. In that case, board code should also not insist on the creation of the board-default FDC. The board-default FDC will still be created if the user requests a floppy drive with "-drive if=floppy". Additionally, separate FDCs can be specified manually with "-device isa-fdc". They allow the -device isa-fdc,driveA=... syntax that is more flexible than the one required by the board-default FDC: -global isa-fdc.driveA=... This patch doesn't change the behavior observably, as all Q35 machine types have "no_floppy = 0".

2015-05-31i386/pc: pc_basic_device_init(): delegate FDC creation requestLaszlo Ersek3-3/+4
This patch introduces no observable change, but it allows the callers of pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or not request) the creation of the FDC explicitly. At the moment both callers pass constant create_fdctrl=true (hence no observable change). Assuming a board passes create_fdctrl=false, "floppy" will be NULL on output, and (beyond the FDC not being created) that NULL will be passed on to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

2015-05-31pc: acpi: fix pvpanic for buggy guestsRadim Krčmář1-1/+4
In the old times, we always had pvpanic in ACPI and a _STA method told the guest not to use it. Automatic generation dropped the _STA method as the specification says that missing _STA means enabled and working. Some guests (Linux) had buggy drivers and this change made them unable to utilize pvpanic. A Linux patch is posted as well, but I think it's worth to make pvpanic useable on old guests at the price of three lines and few bytes of SSDT. The old _STA method was Method (_STA, 0, NotSerialized) { Store (PEST, Local0) If (LEqual (Local0, Zero)) { Return (Zero) } Else { Return (0x0F) }} Igor pointed out that we don't need to use a method to return a constant and that 0xB (don't show in UI) is the common definition now.

2015-05-31pc: Generate init functions with a macroEduardo Habkost2-170/+76
All pc-i440fx and pc-q35 init functions simply call the corresponding compat function and then call the main init function. Use a macro to generate that code.

2015-05-31piix: Eliminate pc_init_pci()Eduardo Habkost1-18/+13
The function is not needed anymore, we can simply call pc_init1() directly. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2015-05-31piix: Add kvmclock_enabled, pci_enabled globalsEduardo Habkost1-7/+15
This looks like a step backwards, but it will allow pc-0.1[0123] and isapc to follow the same compat+init pattern used by the other machine-types, allowing us to generate all init function using the same macro later.

2015-05-31pc: Remove qemu_register_pc_machine() functionEduardo Habkost1-45/+0
The helper is not needed anymore, as the PC machine classes are registered using QOM directly. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2015-05-31pc: Don't use QEMUMachine anymoreEduardo Habkost2-32/+32
Now that we have a DEFINE_PC_MACHINE helper macro that just requires an initialization function, it is trivial to convert them to register a QOM machine class directly, instead of using QEMUMachine.
