Gerd Hoffmann 1fcfdc435a vga: disable global_vmstate for 3.0+ machine types
Move global_vmstate from vga_common_init() parameter to VGACommonState
field.  Set global_vmstate to true for isa vga devices, so nothing
changes here.  virtio-vga and secondary-vga already set global_vmstate
to false so no change here either.  All other pci vga devices get a new
global-vmstate property, defaulting to false.  A compat property flips
it to true for older machine types.

With this in place you don't get a vmstate section naming conflict any
more when adding multiple pci vga devices to your vm.

Eduardo Habkost fd3b02c889 pci: Add INTERFACE_CONVENTIONAL_PCI_DEVICE to Conventional PCI devices
Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of
TYPE_PCI_DEVICE, except:

1) The ones that already have INTERFACE_PCIE_DEVICE set:

* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci
* virtio-pci
* vmxnet3

2) base-pci-bridge

Not all PCI bridges are Conventional PCI devices, so
INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes
that are actually Conventional PCI:

* dec-21154-p2p-bridge
* i82801b11-bridge
* pbm-bridge
* pci-bridge

The direct subtypes of base-pci-bridge not touched by this patch
are:

* xilinx-pcie-root: Already marked as PCIe-only.
* pcie-pci-bridge: Already marked as PCIe-only.
* pcie-port: all non-abstract subtypes of pcie-port are already
  marked as PCIe-only devices.

3) megasas-base

Not all megasas devices are Conventional PCI devices, so the
interface names are added to the subclasses registered by
megasas_register_types(), according to information in the
megasas_devices[] array.

"megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add
INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

Halil Pasic d2164ad35c vmstate: error hint for failed equal checks
In some cases a failing VMSTATE_*_EQUAL does not mean we detected a bug,
but it's actually the best we can do. Especially in these cases a verbose
error message is required.

Let's introduce infrastructure for specifying a error hint to be used if
equal check fails. Let's do this by adding a parameter to the _EQUAL
macros called _err_hint. Also change all current users to pass NULL as
last parameter so nothing changes for them.

Gerd Hoffmann 7e486f7577 vmsvga: shadow fifo registers
The fifo is normal ram.  So kvm vcpu threads and qemu iothread can
access the fifo in parallel without syncronization.  Which in turn
implies we can't use the fifo pointers in-place because the guest
can try changing them underneath us.  So add shadows for them, to
make sure the guest can't modify them after we've applied sanity
checks.

Markus Armbruster da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef.  Since then, we've moved to include qemu/osdep.h
everywhere.  Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.

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.

Paolo Bonzini 2d1a35bef0 memory: differentiate memory_region_is_logging and memory_region_get_dirty_log_mask
For now memory regions only track DIRTY_MEMORY_VGA individually, but
this will change soon.  To support this, split memory_region_is_logging
in two functions: one that returns a given bit from dirty_log_mask,
and one that returns the entire mask.  memory_region_is_logging gets an
extra parameter so that the compiler flags misuse.

While VGA-specific users (including the Xen listener!) will want to keep
checking that bit, KVM and vhost check for "any bit except migration"
(because migration is handled via the global start/stop listener
callbacks).

Gerd Hoffmann 30f1e661b6 console: stop using PixelFormat
With this patch the qemu console core stops using PixelFormat and pixman
format codes side-by-side, pixman format code is the primary way to
specify the DisplaySurface format:

 * DisplaySurface stops carrying a PixelFormat field.
 * qemu_create_displaysurface_from() expects a pixman format now.

Functions to convert PixelFormat to pixman_format_code_t (and back)
exist for those who still use PixelFormat.   As PixelFormat allows
easy access to masks and shifts it will probably continue to exist.

Juan Quintela d49805aeea savevm: Remove all the unneeded version_minimum_id_old (x86)
After previous Peter patch, they are redundant.  This way we don't
assign them except when needed.  Once there, there were lots of case
where the ".fields" indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

this fixes invalid rectangle updates observed after commit 12b316d
with the vmware VGA driver. The issues occured because the server
and client surface update seems to be out of sync at some points
and the max width of the surface is not dividable by
VNC_DIRTY_BITS_PER_PIXEL (16).

Gerd Hoffmann 2c62f08ddb console: simplify screendump
Screendumps are alot simpler as we can update non-active
QemuConsoles now.  So we only need to update the QemuConsole
we want write out, then dump the DisplaySurface content into
a ppm file.  Done.

No console switching needed.  No special support code in the
gfx card emulation needed.  Zap it all.  Also move ppm_save
out of the vga code and next to the qmp_screendump function.

For now screen dumping is limited to console #0 (like it used
to be), even though it is dead simple to extend it to other
consoles.  I wanna finish the console cleanup before setting
new qapi interfaces into stone.

Gerd Hoffmann eb2f9b024d hw/vmware_vga.c: various vmware vga fixes.
Hardcode depth to 32 bpp.  It effectively was that way before because
that is the default surface depth, this just makes it explicit in the
code.

Rename depth to new_depth to make it consistent with the new_width +
new_height names.  In theory we can make new_depth changeable (i.e.
allow the guest to fill in -- say -- 16 there).  In practice the guests
don't try, the X-Server refuses to start if you ask it to use 16bpp
depth (via DefaultDepth in the Screen section).

Always return the correct rmask+gmask+bmask values for the given
new_depth.

Fix mode setting to also verify at new_depth to make sure we have a
correct DisplaySurface, even if the current video mode happes to be
16bpp (set by vgabios via bochs vbe interface).  While being at it
switch over to use qemu_create_displaysurface_from, so the surface is
backed by guest-visible video memory and we save a memcpy.
