9 years agopc: Ensure non-zero CPU ref count after attaching to ICC bus

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.

xen/MSI-X: limit error messages

Limit error messages resulting from bad guest behavior to avoid allowing
the guest to cause the control domain's disk to fill.

The first message in pci_msix_write() can simply be deleted, as this
is indeed bad guest behavior, but such out of bounds writes don't
really need to be logged.

The second one is more problematic, as there guest behavior may only
appear to be wrong: For one, the old logic didn't take the mask-all bit
into account. And then this shouldn't depend on host device state (i.e.
the host may have masked the entry without the guest having done so).
Plus these writes shouldn't be dropped even when an entry is unmasked.
Instead, if they can't be made take effect right away, they should take
effect on the next unmasking or enabling operation - the specification
explicitly describes such caching behavior. Until we can validly drop
the message (implementing such caching/latching behavior), issue the
message just once per MSI-X table entry.

Note that the log message in pci_msix_read() similar to the one being
removed here is not an issue: "addr" being of unsigned type, and the
maximum size of the MSI-X table being 32k, entry_nr simply can't be
negative and hence the conditonal guarding issuing of the message will
never be true.

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".

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.

9 years agopc: Define MACHINE_OPTIONS macros consistently for all machines
Eduardo Habkost [Fri, 15 May 2015 17:18:52 +0000 (14:18 -0300)]
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.

John Snow [Tue, 12 May 2015 19:53:01 +0000 (15:53 -0400)]
qapi: add dirty bitmap status

Bitmaps can be in a handful of different states with potentially
more to come as we tool around with migration and persistence patches.

Management applications may need to know why certain bitmaps are
unavailable for various commands, e.g. busy in another operation,
busy being migrated, etc.

Right now, all we offer is BlockDirtyInfo's boolean member 'frozen'.
Instead of adding more booleans, replace it by an enumeration member
'status' with values 'active' and 'frozen'.  Then add new value
'disabled'.

Incompatible change.  Fine because the changed part hasn't been
released so far.

target-arm: Avoid buffer overrun on UNPREDICTABLE ldrd/strd

A LDRD or STRD where rd is not an even number is UNPREDICTABLE.
We were letting this fall through, which is OK unless rd is 15,
in which case we would attempt to do a load_reg or store_reg
to a nonexistent r16 for the second half of the double-word.
Catch the odd-numbered-rd cases and UNDEF them instead.

To do this we rearrange the structure of the code a little
so we can put the UNDEF catches at the top before we've
allocated TCG temporaries.
