      hw: include hw header files with full paths · 83c9f4ca
      由 Paolo Bonzini 提交于 
      Done with this script:

cd hw
for i in `find . -name '*.h' | sed 's/^..//'`; do
  echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,'
done | sed -i -f - `find . -type f`

This is so that paths remain valid as files are moved.

Instead, files in hw/dataplane are referenced with the relative path.
We know they are not going to move to include/, and they are the only
include files that are in subdirectories _and_ move.

      Make all static TypeInfos const · 8c43a6f0
      由 Andreas Färber 提交于 
      Since 39bffca2 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information
and should therefore be const.

Fix the documented QOM examples:

 sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h

Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:

 sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
 sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c

This also avoids to piggy-back these changes onto real functional
changes or other refactorings.

      Rename target_phys_addr_t to hwaddr · a8170e5e
      由 Avi Kivity 提交于 
      target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific).  Replace it with a finger-friendly,
standards conformant hwaddr.

Outstanding patchsets can be fixed up with the command

  git rebase -i --exec 'find -name "*.[ch]"

      target-i386: move cpu halted decision into x86_cpu_reset · dd673288
      由 Igor Mammedov 提交于 
      MP initialization protocol differs between cpu families, and for P6 and
onward models it is up to CPU to decide if it will be BSP using this
protocol, so try to model this. However there is no point in implementing
MP initialization protocol in qemu. Thus first CPU is always marked as BSP.

This patch:
 - moves decision to designate BSP from board into cpu, making cpu
self-sufficient in this regard. Later it will allow to cleanup hw/pc.c
and remove cpu_reset and wrappers from there.
 - stores flag that CPU is BSP in IA32_APIC_BASE to model behavior
described in Inted SDM vol 3a part 1 chapter 8.4.1
 - uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP

patch is based on Jan Kiszka's proposal:

      kvmvapic: Introduce TPR access optimization for Windows guests · e5ad936b
      由 Jan Kiszka 提交于 
      This enables acceleration for MMIO-based TPR registers accesses of
32-bit Windows guest systems. It is mostly useful with KVM enabled,
either on older Intel CPUs (without flexpriority feature, can also be
manually disabled for testing) or any current AMD processor.

The approach introduced here is derived from the original version of
qemu-kvm. It was refactored, documented, and extended by support for
user space APIC emulation, both with and without KVM acceleration. The
VMState format was kept compatible, so was the ABI to the option ROM
that implements the guest-side para-virtualized driver service. This
enables seamless migration from qemu-kvm to upstream or, one day,
between KVM and TCG mode.

The basic concept goes like this:
 - VAPIC PV interface consisting of I/O port 0x7e and (for KVM in-kernel
   irqchip) a vmcall hypercall is registered
 - VAPIC option ROM is loaded into guest
 - option ROM activates TPR MMIO access reporting via port 0x7e
 - TPR accesses are trapped and patched in the guest to call into option
   ROM instead, VAPIC support is enabled
 - option ROM TPR helpers track state in memory and invoke hypercall to
   poll for pending IRQs if required

      target-i386: Add infrastructure for reporting TPR MMIO accesses · d362e757
      由 Jan Kiszka 提交于 
      This will allow the APIC core to file a TPR access report. Depending on
the accelerator and kernel irqchip mode, it will either be delivered
right away or queued for later reporting.

In TCG mode, we can restart the triggering instruction and can therefore
forward the event directly. KVM does not allows us to restart, so we
postpone the delivery of events recording in the user space APIC until
the current instruction is completed.

Note that KVM without in-kernel irqchip will report the address after
the instruction that triggered the access.

      qdev: register all types natively through QEMU Object Model · 39bffca2
      由 Anthony Liguori 提交于 
      This was done in a mostly automated fashion.  I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass
registration functions.

The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.

Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.

We are almost fully converted to QOM after this commit.

      apic: Open-code timer save/restore · 7a380ca3
      由 Jan Kiszka 提交于 
      To enable migration between accelerated and non-accelerated APIC models,
we will need to handle the timer saving and restoring specially and can
no longer rely on the automatics of VMSTATE_TIMER. Specifically,
accelerated model will not start any QEMUTimer.

This patch therefore factors out the generic bits into apic_next_timer
and use a post-load callback to implemented model-specific logic.

      apic: Factor out base class for KVM reuse · dae01685
      由 Jan Kiszka 提交于 
      The KVM in-kernel APIC model will reuse parts of the user space model
while providing the same frontend view to guest and most management
interfaces.

Factor out an APIC base class to encapsulate those parts that will be
shared by user space and KVM model. This class offers callback hooks for
init, base/tpr setting, and the external NMI delivery that will be
set via APICCommonInfo structure and implemented specifically in the
subclasses.
