2010-12-28target-sparc: fix udiv(cc) and sdiv(cc)Aurelien Jarno
Since commit 5a4bb580cdb10b066f9fd67658b31cac4a4ea5e5, Xorg crashes on a Debian Etch image. The commit itself is fine, but it triggers a bug due to wrong computation of flags for udiv(cc) and sdiv(cc). This patch only compute cc_src2 for the cc version of udiv/sdiv. It also moves the update of cc_dst and cc_op to the helper, as it is faster doing it here when there is already an helper.

2010-12-27Fix migrate set speed doc argLuiz Capitulino
We used to ignore any fractional part in 0.13, but due to recent changes (started with 9f9b17a4f0865286391e4d3a0a735230122a2289) migrate_set_speed will reject the fractional part. We don't expect existing clients to be relying on this, but we need to update the documentation to reflect the change.

2010-12-27pci: fix migration path for devices behind bridgesMichael S. Tsirkin
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.

2010-12-20qbus: register reset handler for qbus whose parent is NULLIsaku Yamahata
Stefan Weil reported the regression caused by ec990eb622ad46df5ddcb1e94c418c271894d416 as follows > The second regression also occurs with MIPS malta. > Networking no longer works with the default pcnet nic. > > This is caused because the reset function for pcnet is no > longer called during system boot. The result in an invalid > mac address (all zero) and a non-working nic. > > For this second regression I still have no simple solution. > Of course mips_malta.c should be converted to qdev which > would fix both problems (but only for malta system emulation). 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. Reported-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: "Michael S.

2010-12-18win32: Fix CRLF problem in make_device_config.shStefan Weil
QEMU source code with CRLF line endings which is quite common on windows hosts fails with current make_device_config.sh. The awk script gets the name of the included file with \r, so instead of pci.mak it will search for pci.mak\r which of course does not work. Fix this by removing any \r. v2: Avoid using sub() and \r with awk because they are unsupported on some platforms. Use tr to remove \r.
