[Qemu-devel] [PULL 01/24] make: fix where dependency *.d are stored.

[Michael S. Tsirkin]

From: Victor Kaplansky <victork@redhat.com>

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.

[Qemu-devel] [PULL 02/24] make: load only required dependency files.

[Michael S. Tsirkin]

From: Victor Kaplansky <victork@redhat.com>

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".

[Qemu-devel] [PULL 03/24] piix: Document coreboot-specific RAM size config register

[Michael S. Tsirkin]

From: Eduardo Habkost <ehabkost@redhat.com>

The existing i440fx initialization code sets a PCI config register that
isn't documented anywhere in the Intel 440FX datasheet. Register 0x57 is
DRAMC (DRAM Control) and has nothing to do with the RAM size.

This was implemented in commit ec5f92ce6ac8ec09056be77e03c941be188648fa
because old coreboot code tried to read registers 0x5a-0x5f,0x56,0x57 to
get the RAM size from QEMU, but I couldn't find out why coreboot did
that. I assume it was a mistake, and the original code was supposed to
be reading the DRB[0-7] registers (offsets 0x60-0x67).

Document that coreboot-specific register offset in a macro and a
comment, for future reference.

[Qemu-devel] [PULL 04/24] pc: Use PC_COMPAT_* for CPUID feature compatibility

[Michael S. Tsirkin]

From: Eduardo Habkost <ehabkost@redhat.com>

Now we can use compat_props to keep CPUID feature compatibility, using
the boolean QOM properties for CPUID feature flags.

This simplifies the compatibility code, and reduces duplication between
pc_piix.c and pc_q35.c.

[Qemu-devel] [PULL 06/24] pc: Use error_abort when registering properties

[Michael S. Tsirkin]

From: Eduardo Habkost <ehabkost@redhat.com>

No errors should happen when registering the properties, but we
shouldn't silently ignore them if they happen.

[Qemu-devel] [PULL 09/24] pc: Eliminate pc_common_machine_options()

[Michael S. Tsirkin]

From: Eduardo Habkost <ehabkost@redhat.com>

All TYPE_PC_MACHINE subclasses call pc_common_machine_options().
TYPE_PC_MACHINE can simply initialize the common options on class_init
directly.

[Qemu-devel] [PULL 10/24] pc: Eliminate pc_default_machine_options()

[Michael S. Tsirkin]

From: Eduardo Habkost <ehabkost@redhat.com>

The only PC machines that didn't call pc_default_machine_options() were
isaps and xenfv. Both were already overwriting max_cpus, and only isapc
was not overwriting hot_add_cpu.

After making isapc set hot_add_cpu to NULL, we can move the
pc_default_machine_options() code the PC common class_init.

[Qemu-devel] [PULL 11/24] pc: Use PCMachineState for pc_cmos_init() argument

[Michael S. Tsirkin]

From: Eduardo Habkost <ehabkost@redhat.com>

pc_cmos_init() already expects a PCMachineState object, there's no point
in upcasting it to MachineState before calling the function.

While doing it, reorder the arguments so PCMachineState is the first
function argument.

[Qemu-devel] [PULL 18/24] pci: allow 0 address for PCI IO/MEM regions

[Michael S. Tsirkin]

From: Laurent Vivier <lvivier@redhat.com>

Some kernels program a 0 address for io regions. PCI 3.0 spec
section 6.2.5.1 doesn't seem to disallow this.

based on patch by Michael Roth <mdroth@linux.vnet.ibm.com>

Add pci_allow_0_addr in MachineClass to conditionally
allow addr 0 for pseries, as this can break other architectures.

This patch allows to hotplug PCI card in pseries machine, as the first
added card BAR0 is always set to 0 address.

This as a temporary hack, waiting to fix PCI memory priorities for more
machine types...

[Qemu-devel] [PULL 19/24] virtio-net: remove useless codes

[Michael S. Tsirkin]

After commit 40bad8f3deba15e2074ff34cfe923c12916b1cc5("virtio-net: fix
used len for tx"), async_tx.len was no longer used afterwards. So
remove useless codes with it.

[Qemu-devel] [PULL 20/24] acpi: avoid potential uninitialized access to cpu_hp_io_base

In acpi_get_pm_info() some of the fields are pre-initialized

[Qemu-devel] [PULL 22/24] smbios: remove dependency on x86 e820 tables

[Michael S. Tsirkin]

From: Wei Huang <wei@redhat.com>

Current smbios builds type 19 table from e820, which is x86 specific.
This patch removes smbios' dependency on e820 by passing an array
of memory area to smbios_get_tables().

[Qemu-devel] [PULL 23/24] smbios: move smbios code into a common folder

[Michael S. Tsirkin]

From: Wei Huang <wei@redhat.com>

To share smbios among different architectures, this patch moves SMBIOS
code (smbios.c and smbios.h) from x86 specific folders into new
hw/smbios directories. As a result, CONFIG_SMBIOS=y is defined in
x86 default config files.
