      cirrus_vga: fix division by 0 for color expansion rop · 92d675d1
      由 Aurelien Jarno 提交于 
      Commit d85d0d38 introduces a regression
with Windows ME that leads to a division by 0 and a crash.

It uses the color expansion rop with the source pitch set to 0. This is
something allowed, as the manual explicitely says "When the source of
color-expand data is display memory, the source pitch is ignored.".

This patch fixes this regression by computing sx, sy and others
variables only if they are going to be used later, that is for a plain
copy ROP. It basically consists in moving code.

      Fix curses on big endian hosts · 9ae19b65
      由 Aurelien Jarno 提交于 
      On big endian hosts, the curses interface is unusable: the emulated
graphic card only displays garbage, while the monitor interface displays
nothing (or rather only spaces).

The curses interface is waiting for data in native endianness, so
console_write_ch() should not do any conversion. The conversion should
be done when reading the video buffer in hw/vga.c. I supposed this
buffer is in little endian mode, though it's not impossible that the
data is actually in guest endianness. I currently have no big endian
guest to way (they all switch to graphic mode immediately).

      pci: fix migration path for devices behind bridges · a6a7005d
      由 Michael S. Tsirkin 提交于 
      The device path used for migration is currently broken for
for all devices behind a nested bridge.

Replace this by a hierarchical list of slot/function numbers, walking
the path from root down to device. Add :00 after the domain number
so that if there are no nested bridges, this is compatible
with what we have now.

Note: as pointed out by Gleb, using openfirmware paths
might be cleaner, doing this would break compatibility though,
and the IDs used are not guest or user visible at all,
so breaking the compatibility is probably not worth it.

      qbus: register reset handler for qbus whose parent is NULL · 80376c3f
      由 Isaku Yamahata 提交于 
      Stefan Weil reported the regression caused by
ec990eb6 as follows

The issue is, it is assumed that all qbuses, qdeves are under
main_system_bus. But there are qbuses whose parent is NULL. So it
is necessary to trigger reset for those qbuses.
(On the other hand, if NULL is passed to qdev_create(), its parent bus
is main_system_bus.)
Ideally those buses should be moved under bus controller
device which is qdev. But it's not done yet.
So register qbus reset handler for qbus whose parent is NULL.
