Xiao Guangrong 87252e1b61 nvdimm acpi: build ACPI NFIT table
NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT)

Currently, we only support PMEM mode. Each device has 3 structures:
- SPA structure, defines the PMEM region info

- MEM DEV structure, it has the @handle which is used to associate specified
  ACPI NVDIMM  device we will introduce in later patch.
  Also we can happily ignored the memory device's interleave, the real
  nvdimm hardware access is hidden behind host

- DCR structure, it defines vendor ID used to associate specified vendor
  nvdimm driver. Since we only implement PMEM mode this time, Command
  window and Data window are not needed

The NVDIMM functionality is controlled by the parameter, 'nvdimm', which
is introduced for the machine, there is a example to enable it:
-machine pc,nvdimm -m 8G,maxmem=100G,slots=100  -object \
memory-backend-file,id=mem1,share,mem-path=/tmp/nvdimm1,size=10G -device \
nvdimm,memdev=mem1,id=nv1

It is disabled on default

Paolo Bonzini 15eafc2e60 kvm: x86: add support for KVM_CAP_SPLIT_IRQCHIP
This patch adds support for split IRQ chip mode. When
KVM_CAP_SPLIT_IRQCHIP is enabled:

    1.) The PIC, PIT, and IOAPIC are implemented in userspace while
    the LAPIC is implemented by KVM.

    2.) The software IOAPIC delivers interrupts to the KVM LAPIC via
    kvm_set_irq. Interrupt delivery is configured via the MSI routing
    table, for which routes are reserved in target-i386/kvm.c then
    configured in hw/intc/ioapic.c

    3.) KVM delivers IOAPIC EOIs via a new exit KVM_EXIT_IOAPIC_EOI,
    which is handled in target-i386/kvm.c and relayed to the software
    IOAPIC via ioapic_eoi_broadcast.

Eric Blake 7fb1cf1606 qapi: Don't let implicit enum MAX member collide
Now that we guarantee the user doesn't have any enum values
beginning with a single underscore, we can use that for our
own purposes.  Renaming ENUM_MAX to ENUM__MAX makes it obvious
that the sentinel is generated.

This patch was mostly generated by applying a temporary patch:

|diff --git a/scripts/qapi.py b/scripts/qapi.py
|index e6d014b..b862ec9 100644
|--- a/scripts/qapi.py
|+++ b/scripts/qapi.py
|@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = {
|     max_index = c_enum_const(name, 'MAX', prefix)
|     ret += mcgen('''
|     [%(max_index)s] = NULL,
|+// %(max_index)s
| };
| ''',
|                max_index=max_index)

then running:

$ cat qapi-{types,event}.c tests/test-qapi-types.c |
    sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list
$ git grep -l _MAX | xargs sed -i -f list

The only things not generated are the changes in scripts/qapi.py.

Rejecting enum members named 'MAX' is now useless, and will be dropped
in the next patch.

Gabriel L. Somlo 3f8752b4e5 fw_cfg: remove offset argument from callback prototype
Read callbacks are now only invoked at item selection, before any
data is read. As such, the value of the offset argument passed to
the callback will always be 0. Also, the two callback instances
currently in use both leave their offset argument unused.

This patch removes the offset argument from the fw_cfg read callback
prototype, and from the currently available instances. The unused
(write) callback prototype is also removed (write support was removed
earlier, in commit 023e3148).

Using access() is a time-of-check/time-of-use race condition.  It is
okay to use them to provide better error messages, but that is pretty
much it.

In this case we can get the same error from fopen(), so just use
strerror and errno there---which actually improves the error
message most of the time.

The commit 317b0a6d8 fixed an issue which caused by the outdated
env->tsc value, but the fix lead to 'cpu_synchronize_all_states()'
called twice during live migration. The 'cpu_synchronize_all_states()'
takes about 130us for a VM which has 4 vcpus, it's a bit expensive.

Synchronize the whole CPU context just for updating env->tsc is too
wasting, this patch use a new function to update the env->tsc.
Comparing to 'cpu_synchronize_all_states()', it only takes about 20us.

Eduardo Habkost de796d93f5 pc: Set hw_version on all machine classes
In 2012, QEMU had a bug where it exposed QEMU version information to the
guest, meaning a QEMU upgrade would expose different hardware to the
guest OS even if the same machine-type is being used.

The bug was fixed by commit 93bfef4c6e, on
all machines up to pc-1.0. But we kept introducing the same bug on all
newer machines since then. That means we are breaking guest ABI every
time QEMU was upgraded.

Fix this by setting the hw_version on all PC machines, making sure the
hardware won't change when upgrading QEMU.

Note that QEMU_VERSION was "1.0" in QEMU 1.0, but starting on QEMU
1.1.0, it started following the "x.y.0" pattern. We have to follow it,
to make sure we use the right QEMU_VERSION string from each QEMU
release.

The 2.5 machine classes could have hw_version unset, because the default
value for qemu_get_version() is QEMU_VERSION. But I decided to set it
explicitly to QEMU_VERSION so we don't forget to update it to "2.5.0"
after we release 2.5.0 and create a 2.6 machine class.

Eduardo Habkost dbb7405d8c xen-platform: Ensure xen is enabled when initializing
The xen-platform code crashes on reset if the xen backend is not
initialized, because it calls xc_hvm_set_mem_type(). Ensure xen-platform
won't be created without initializing the xen backend.

The assert can't be triggered by the user because the device is not
hotpluggable, and the only code creating it (at pc_xen_hvm_init())
already checks xen_enabled().

Pavel Fedin dc9f06ca81 kvm: Pass PCI device pointer to MSI routing functions
In-kernel ITS emulation on ARM64 will require to supply requester IDs.
These IDs can now be retrieved from the device pointer using new
pci_requester_id() function.

This patch adds pci_dev pointer to KVM GSI routing functions and makes

- Use a hash table indexed on bus pointers to store information about buses
  instead of using the bus numbers.
  Bus pointers are stored in a new VTDBus struct together with the vector
  of device address space pointers indexed by devfn.
- The bus number is still used for lookup for selective SID based invalidate,
  in which case the bus number is lazily resolved from the bus hash table and
  cached in a separate index.

Markus Armbruster f8ed85ac99 Fix bad error handling after memory_region_init_ram()
Symptom:

    $ qemu-system-x86_64 -m 10000000
    Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456:
    upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory
    Aborted (core dumped)

Root cause: commit ef701d7 screwed up handling of out-of-memory
conditions.  Before the commit, we report the error and exit(1), in
one place, ram_block_add().  The commit lifts the error handling up
the call chain some, to three places.  Fine.  Except it uses
&error_abort in these places, changing the behavior from exit(1) to
abort(), and thus undoing the work of commit 3922825 "exec: Don't
abort when we can't allocate guest memory".

The three places are:

* memory_region_init_ram()

  Commit 4994653 (right after commit ef701d7) lifted the error
  handling further, through memory_region_init_ram(), multiplying the
  incorrect use of &error_abort.  Later on, imitation of existing
  (bad) code may have created more.

* memory_region_init_ram_ptr()

  The &error_abort is still there.

* memory_region_init_rom_device()

  Doesn't need fixing, because commit 33e0eb5 (soon after commit
  ef701d7) lifted the error handling further, and in the process
  changed it from &error_abort to passing it up the call chain.
  Correct, because the callers are realize() methods.

Fix the error handling after memory_region_init_ram() with a
Coccinelle semantic patch:

    @r@
    expression mr, owner, name, size, err;
    position p;
    @@
            memory_region_init_ram(mr, owner, name, size,
    (
    -                              &error_abort
    +                              &error_fatal
    |
                                   err@p
    )
                                  );
    @script:python@
        p << r.p;
    @@
    print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column)

When the last argument is &error_abort, it gets replaced by
&error_fatal.  This is the fix.

If the last argument is anything else, its position is reported.  This
lets us check the fix is complete.  Four positions get reported:

* ram_backend_memory_alloc()

  Error is passed up the call chain, ultimately through
  user_creatable_complete().  As far as I can tell, it's callers all
  handle the error sanely.

* fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize()

  DeviceClass.realize() methods, errors handled sanely further up the
  call chain.

We're good.  Test case again behaves:

    $ qemu-system-x86_64 -m 10000000
    qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory
    [Exit 1 ]

The next commits will repair the rest of commit ef701d7's damage.

Tiejun Chen 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).

Victor Kaplansky 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.

Eduardo Habkost 4421c6a38a pc: fix reuse of pc-i440fx-2.4 in pc-i440fx-2.3
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().

Laszlo Ersek 220a884642 hw/i386/pc: don't carry FDC from pc_basic_device_init() to pc_cmos_init()
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.

pc_init1() | pc_q35_init()
  pc_basic_device_init()
  pc_cmos_init()

Laszlo Ersek 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.

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.

why it is opencoded.  For new machine types, it is required that machine
