      usb: the big rename · f1ae32a1
      由 Gerd Hoffmann 提交于 
      Reorganize usb source files.  Create a new hw/usb/ directory and move
all usb source code to that place.  Also make filenames a bit more
descriptive.  Host adapters are prefixed with "hch-" now, usb device
emulations are prefixed with "dev-".  Fixup paths Makefile and include
paths to make it compile.  No code changes.

      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

      w32: Build windows and console executables · 0fa5491e
      由 Stefan Weil 提交于 
      System emulation executables with SDL are typically windows
executables. Sometimes console executables are more useful,
so create both variants if linker option -mwindows was detected.

v2:
This version uses QEMU_PROGW / QEMU_PROG instead of QEMU_PROG / QEMU_PROGC.

      kvm: x86: Add user space part for in-kernel IOAPIC · a39c1d47
      由 Jan Kiszka 提交于 
      This introduces the KVM-accelerated IOAPIC model 'kvm-ioapic' and
extends the IRQ routing setup by the 0->2 redirection when needed.

The kvm-ioapic model has a property that allows to define its GSI base
for injecting interrupts into the kernel model. This will allow to
disentangle PIC and IOAPIC pins for chipsets that support more
sophisticated IRQ routes than the PIIX3. So far the base is kept at 0,
i.e. PIC and IOAPIC share pins 0..15.

      kvm: x86: Add user space part for in-kernel i8259 · 10b61882
      由 Jan Kiszka 提交于 
      Introduce the alternative 'kvm-i8259' device model that exploits KVM
in-kernel acceleration.

The PIIX3 initialization code is furthermore extended by KVM specific
IRQ route setup. GSI injection differs in KVM mode from the user space
model. As we can dispatch ISA-range IRQs to both IOAPIC and PIC inside
the kernel, we do not need to inject them separately. This is reflected
by a KVM-specific GSI handler.

      kvm: x86: Add user space part for in-kernel APIC · 680c1c6f
      由 Jan Kiszka 提交于 
      This introduces the alternative APIC device which makes use of KVM's
in-kernel device model. External NMI injection via LINT1 is emulated by
checking the current state of the in-kernel APIC, only injecting a NMI
into the VCPU if LINT1 is unmasked and configured to DM_NMI.

MSI is not yet supported, so we disable this when the in-kernel model is
in use.

      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.
