bd8107d730 igd gfx passthrough: create a isa bridge
Currently IGD drivers always need to access PCH by 1f.0. But we
don't want to poke that directly to get ID, and although in real
world different GPU should have different PCH. But actually the
different PCH DIDs likely map to different PCH SKUs. We do the
same thing for the GPU. For PCH, the different SKUs are going to
be all the same silicon design and implementation, just different
features turn on and off with fuses. The SW interfaces should be
consistent across all SKUs in a given family (eg LPT). But just
same features may not be supported.

Most of these different PCH features probably don't matter to the
Gfx driver, but obviously any difference in display port connections
will so it should be fine with any PCH in case of passthrough.

So currently use one PCH version, 0x8c4e, to cover all HSW(Haswell)
scenarios, 0x9cc3 for BDW(Broadwell).

bcd7461e7e hw/pci-assign: split pci-assign.c
We will try to reuse assign_dev_load_option_rom in xen side, and
especially its a good beginning to unify pci assign codes both on
kvm and xen in the future.

3385e8e264 pc: memhotplug: fix incorrectly set reserved-memory-end
reserved-memory-end tells firmware address from which
it could start treating memory as PCI address space
and map PCI BARs after it to avoid collisions with
RAM.
Currently it is incorrectly pointing to address where
hotplugged memory range starts which could redirect
hotplugged RAM accesses to PCI BARs when firmware
maps them over RAM or viceverse.
Fix this by pointing reserved-memory-end to the end
of memory hotplug area.

27fa747980 make: load only required dependency files.
The old rules.mak loads dependency .d files using include directive
with file glob pattern "*.d". This breaks the build when build tree has
left-over *.d files from another build.

This patch fixes this by
  - loading precise list of .d files made from *.o and *.mo.
  - specifying explicit list of required dependency info files for
     *.hex autogenerated sources.

Note that Makefile still includes some .d in root directory by including
"*.d".

998b7b1db4 make: fix where dependency *.d are stored.
In rules like "bar/%.o: %.c" there is a difference between $(*D) and
$(@D). $(*D) expands to '.', while $(@D) expands to 'bar'.  It is
cleaner to generate *.d in the same directory where appropriate *.o
resides. This allows precise including of dependency info from .d files.

As a hack, we also touch two sources for generated *.hex files.  Without
this hack, anyone doing "git pull; make" will not get *.hex rebuilt
correctly since the dependency file would be missing.

commit fddd179ab9,
    "pc: Convert *_MACHINE_OPTIONS macros into functions"
broke the chaining of *_machine_options() functions on
pc-i440fx-2.3, at:

  -#define PC_I440FX_2_3_MACHINE_OPTIONS \
  -    PC_I440FX_2_4_MACHINE_OPTIONS, \
  -    .alias = NULL, \
  -    .is_default = 0
  +static void pc_i440fx_2_3_machine_options(QEMUMachine *m)
  +{
  +    pc_i440fx_machine_options(m);
  +    m->alias = NULL;
  +    m->is_default = 0;
  +}

I have replaced PC_I440FX_2_4_MACHINE_OPTIONS with a
pc_i440fx_machine_options() call, instead of calling
pc_i440fx_2_4_machine_options(). This broke the setting of default_machine_opts
and default_display on pc-i440fx-{2.0,2,1,2.2,2.3}.

Fix this by making pc_i440fx_2_3_machine_options() reuse
pc_i440fx_2_4_machine_options().

Thanks to the last patch, pc_cmos_init() doesn't need the (optional)
board-default FDC any longer as an input parameter. Update
pc_basic_device_init() not to hand it back to pc_init1() / pc_q35_init(),
and update the latter not to carry the FDC to pc_cmos_init(). This
simplifies the code.

b86f46132c hw/i386/pc: reflect any FDC @ ioport 0x3f0 in the CMOS
With the pc-q35-2.4 machine type, if the user creates an ISA FDC manually:

  -device isa-fdc,driveA=drive-fdc0-0-0 \
  -drive file=...,if=none,id=drive-fdc0-0-0,format=raw

then the board-default FDC will be skipped, and only the explicitly
requested FDC will exist. qtree-wise, this is correct; however such an FDC
is currently not registered in the CMOS, because that code is only reached
for the board-default FDC.

The pc_cmos_init_late() one-shot reset handler -- one-shot because the
CMOS is not reprogrammed during warm reset -- should search for any ISA
FDC devices, created implicitly (by board code) or explicitly, and set the
CMOS accordingly to the ISA FDC(s) with iobase=0x3f0:

- if there is no such FDC, report both drives absent,
- if there is exactly one such FDC, report its drives in the CMOS,
- if there are more than one such FDCs, then pick one (it is not specified
  which one), and print a warning about the ambiguity.

7444ca4ee2 hw/i386/pc: factor out pc_cmos_init_floppy()
Extract the pc_cmos_init_floppy() function from pc_cmos_init(). The
function sets two RTC registers: floppy drive types (0x10), overwriting
the earlier value in there), and REG_EQUIPMENT_BYTE (0x14), setting bits
in the prior value.

920557971b ich9: add TCO interface emulation
This interface provides some registers within a 32-byte range and can be
acessed through PCI-to-LPC bridge interface (PMBASE + 0x60).

It's commonly used as a watchdog timer to detect system lockups through
SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If
NO_REBOOT bit is not set in GCS (General Control and Status register),
the system will be resetted upon second timeout if TCO_RLD register
wasn't previously written to prevent timeout.

This patch adds support to TCO watchdog logic and few other features
like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection,
etc. are not implemented yet.

4ebc736e99 i386/acpi-build: fix PXB workarounds for unsupported BIOSes
The patch

  apci: fix PXB behaviour if used with unsupported BIOS

uses the following condition to see if a "PXB mem/IO chunk" has *not* been
configured by the BIOS:

  (!range_base || range_base > range_limit)

When this condition evaluates to true, said patch *omits* the
corresponding entry from the _CRS.

Later on the patch checks for the opposite condition (with the intent of
*adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been
configured). Unfortunately, the condition was negated incorrectly: only
the first ! operator was removed, which led to the nonsensical expression

  (range_base || range_base > range_limit)

leading to bogus entries in the _CRS, and causing BSOD in Windows Server
2012 R2 when it runs on OVMF.

The correct negative of the condition seen at the top is

  (range_base && range_base <= range_limit)

Fix the expressions.

c96d9286a6 i386/acpi-build: more traditional _UID and _HID for PXB root buses
The ACPI specification permits the _HID and _UID objects to evaluate to
strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in
the ACPI v6.0 spec.)

With regard to related standards, the UEFI specification can also express
a device address composed from string _HID and _UID identifiers, inside
the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table
49, in the UEFI v2.5 spec.)

However, numeric (integer) contents for both _HID and _UID are more
traditional. They are recommended by the UEFI spec for size reasons:

  [...] the ACPI Device Path node is smaller and should be used if
  possible to reduce the size of device paths that may potentially be
  stored in nonvolatile storage [...]

External tools support them better (for example the --acpi_hid and
--acpi_uid options of "efibootmgr" only take numeric identifiers).
Finally, numeric _HID and _UID contents are existing practice in the QEMU
source.

This patch was tested with a Fedora 20 LiveCD and a preexistent Windows
Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we
get, in the SSDT:

> Scope (\_SB)
> {
>   Device (PC04)
>   {
>     Name (_UID, 0x04)  // _UID: Unique ID
>     Name (_HID, EisaId ("PNP0A03") /* PCI Bus */)  // _HID: Hardware ID

6e7d82497d hw/acpi: piix4_pm_init(): take fw_cfg object no more
This PIIX4 init function has no more reason to receive a pointer to the
FwCfg object. Remove the parameter from the prototype, and update callers.

As a result, the pc_init1() function no longer needs to save the return
value of pc_memory_init() and xen_load_linux(), which makes it more
similar to pc_q35_init().

The return type & value of pc_memory_init() and xen_load_linux() are not
changed themselves; maybe we'll need their return values sometime later.

0f6dd8e1d5 apci: fix PXB behaviour if used with unsupported BIOS
PXB does not work with unsupported bioses, but should
not interfere with normal OS operation.
We don't ship them anymore, but it's reasonable
to keep the work-around until we update the bios in qemu.

Fix this by not adding PXB mem/IO chunks to _CRS
if they weren't configured by BIOS.

0e3bd56294 pc: Ensure non-zero CPU ref count after attaching to ICC bus
Setting the parent bus of a device increases its ref count, which we
ultimately want to level out. However it is only safe to do so after the
last reference to the device in local code, as qom-set or similar operations
might decrease the ref count.

Therefore move the object_unref() from pc_new_cpu() into its callers.

The APIC operations on the last CPU in pc_cpus_init() are still potentially
insecure, but that is beyond the scope of this code movement.

ea96bc629c i386: drop FDC in pc-q35-2.4+ if neither it nor floppy drives are wanted
It is Very annoying to carry forward an outdatEd coNtroller with a mOdern

Hence, let us not instantiate the FDC when all of the following apply:
- the machine type is pc-q35-2.4 or later,
- "-device isa-fdc" is not passed on the command line (nor in the config
  file),
- no "-drive if=floppy,..." is requested.

6cd2234ccb i386/pc_q35: don't insist on board FDC if there's no default floppy
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".

fd53c87cf6 i386/pc: pc_basic_device_init(): delegate FDC creation request
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.

2332333c97 pc: acpi: fix pvpanic for buggy guests
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.

Also, the device used to be PEVT.  (PEVT as in "panic event"?)

b6b5c8e492 pc: Define MACHINE_OPTIONS macros consistently for all machines
Define a MACHINE_OPTIONS macro for each PC machine, and move every field
inside the QEMUMachine structs to the macros, except for name, init, and
compat_props.

This also ensures that all MACHINE_OPTIONS inherit the fields from the
next version, so their definitions carry only the changes that exist
between one version and the next one.

Comments about specific cases:

pc-*-2.1:

  Existing PC_*_2_1_MACHINE_OPTIONS macros were defined as:
      PC_*_MACHINE_OPTIONS,
      .default_machine_opts = "firmware=bios-256k.bin"

  PC_*_2_2_MACHINE_OPTIONS is:
      PC_*_2_3_MACHINE_OPTIONS
  which is expanded to:
      PC_*_MACHINE_OPTIONS,
      .default_machine_opts = "firmware=bios-256k.bin",
      .default_display = "std"

  The only difference between 2_1 and 2_2 is .default_display, that's why
  we didn't reuse PC_*_2_2_MACHINE_OPTIONS. The good news is that having
  multiple initializers for a field is allowed by C99, and the last
  initializer overrides the previous ones.

  So we can reuse the 2_2 macro in 2_1 and define PC_*_2_1_MACHINE_OPTIONS
  as:
      PC_*_2_2_MACHINE_OPTIONS,
      .default_display = NULL

pc-*-1.7:

  PC_*_1_7_MACHINE_OPTIONS was defined as:
      PC_*_MACHINE_OPTIONS

  PC_*_2_0_MACHINE_OPTIONS is defined as:
      PC_*_2_1_MACHINE_OPTIONS
  which is expanded to:
      PC_*_2_2_MACHINE_OPTIONS,
      .default_display = NULL
  which is expanded to:
      PC_*_2_3_MACHINE_OPTIONS,
      .default_display = NULL
  which is expanded to:
      PC_*_MACHINE_OPTIONS,
      .default_machine_opts = "firmware=bios-256k.bin",
      .default_display = "std",
      .default_display = NULL  /* overrides the previous line */

  So, the only difference between PC_*_1_7_MACHINE_OPTIONS and
  PC_*_2_0_MACHINE_OPTIONS is .default_machine_opts (as .default_display
  is not explicitly set by PC_*_MACHINE_OPTIONS so it is NULL).

  So we can keep the macro reuse pattern and define
  PC_*_2_0_MACHINE_OPTIONS as:
      PC_*_2_0_MACHINE_OPTIONS,
      .default_machine_opts = NULL

pc-*-2.4 (alias and is_default fields):

  Set alias and is_default fields inside the 2.4 MACHINE_OPTIONS macro,
  and clear it in the 2.3 macro (that reuses the 2.4 macro).

hw_machine:

  As all the machines older than v1.0 set hw_version explicitly, we can
  safely move the field to the MACHINE_OPTIONS macros without affecting
  the other versions that reuse them.

init function:

  Some machines had the init function set inside the MACHINE_OPTIONS
  macro. Move it to the QEMUMachine declaration, to keep it consistent
  with the other machines.

faf7e4254f piix: Move pc-0.1[23] rombar compat props to PC_COMPAT_0_13
The VGA and vmware-svga rombar compat properties were added by commit
281a26b15b, but only to pc-0.13 and
pc-0.12. This breaks the PC_COMPAT_* nesting pattern we currently
follow.

The new variables will now be inherited by pc-0.11 and older, but
pc-0.11 and pc-0.10 already have PCI.rombar=0 on compat_props, so they
shouldn't be affected at all.

d765519bef piix: Move pc-0.13 virtio-9p-pci compat to PC_COMPAT_0_13
The compat property was added by commit
9dbcca5aa1, and the pc-0.12 and older
machine-types were not changed because virtio-9p-pci was introduced on QEMU
0.13 (commit 9f10751365). The only problem is
that this breaks the PC_COMPAT_* nesting pattern we currently use.

So, move the property to PC_COMPAT_0_13. This make pc-0.12 and older inherit
it, but that shouldn't be an issue as QEMU 0.12 didn't have virtio-9p-pci.

d5303df710 piix: Move pc-0.11 drive version compat props to PC_COMPAT_0_11
The current code setting ide-drive.ver and scsi-disk.ver on pc-0.11
breaks the PC_COMPAT_* nesting pattern we currently use.

As those variables are overwritten in pc-0.10 too, they can be inherited
by pc-0.10 with no side-effects at all.

bb08d8829b piix: Move pc-0.14 qxl compat properties to PC_COMPAT_0_14
Those properties were introduced by commit
3827cdb1c3. They were not duplicated into
pc-0.13 and older because 0.14 was the first QEMU version supporting
qxl. The only problem is that this breaks the PC_COMPAT_* nesting
pattern we currently use.

So, move the properties to PC_COMPAT_0_14. This makes pc-0.13 and older
inherit them, but that shouldn't be an issue as QEMU 0.13 didn't support
qxl.
