      PPC: Change PPC maintainer · 42a87658
      由 Alexander Graf 提交于 
      Since nobody else seems interested in maintaining PPC, let's change the
maintainer to myself. I keep a staging tree anyways and am probably the
person touching most of that code these days.

This changes the maintainer entry for working ppc targets to myself.

      PPC: Make e500 pci byte swap config data · cfb207e6
      由 Alexander Graf 提交于 
      The config data field on the e500 pci controller is in little endian, so we need
to enable byte swap there.

      PPC: Qdev'ify e500 pci · 13b7fdef
      由 Alexander Graf 提交于 
      The e500 PCI controller isn't qdev'ified yet. This leads to severe issues
when running with -drive.

To be able to use a virtio disk with an e500 VM, let's convert the PCI
controller over to qdev.

      KVM: PPC: Add level based interrupt logic · fc87e185
      由 Alexander Graf 提交于 
      KVM on PowerPC used to have completely broken interrupt logic. Usually,
interrupts work by having a PIC that pulls a line up/down, so the CPU knows
that an interrupt is active. This line stays active until some action is
done to the PIC to release the line.

On KVM for PPC, we just checked if there was an interrupt pending and pulled
a line in the kernel module. We never released it though, hoping that kernel
space would just declare an interrupt as released when injected - which is
wrong.

To fix this, we need to completely redesign the interrupt injection logic.
Whenever an interrupt line gets triggered, we need to notify kernel space
that the line is up. Whenever it gets released, we do the same. This way
we can assure that the interrupt state is always known to kernel space.

This fixes random stalls in KVM guests on PowerPC that were waiting for
an interrupt while everyone else thought they received it already.

      isapc: fix segfault. · 02a89b21
      由 Isaku Yamahata 提交于 
      https://bugs.launchpad.net/bugs/611646
reports that ./i386-softmmu/qemu -M isapc segfaults.
This patch fixes the segfault introduced by
f885f1ea

It's because i440fx_state in pc_init1() isn't initialized.

      Fix segfault in mmio subpage handling code. · 95c318f5
      由 Gleb Natapov 提交于 
      It is possible that subpage mmio is registered over existing memory
page. When this happens "memory" will have real memory address and not
index into io_mem array so next access to the page will generate
segfault. It is uncommon to have some part of a page to be accessed as
memory and some as mmio, but qemu shouldn't crash even when guest does
stupid things. So lets just pretend that the rest of the page is
unassigned if guest configure part of the memory page as mmio.
