2011-01-09target-sh4: implement writes to mmaped ITLBAurelien Jarno1-0/+2
Some Linux kernels seems to implement ITLB/UTLB flushing through by writing all TLB entries through the memory mapped interface instead of writing one to MMUCR.TI. Implement memory mapped ITLB write interface so that such kernels can boot. This fixes https://bugs.launchpad.net/bugs/700774 . Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-04cirrus_vga: fix division by 0 for color expansion ropAurelien Jarno1-32/+33
Commit d85d0d3883f5a567fa2969a0396e42e0a662b3fa 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.

2011-01-04Fix curses on big endian hostsAurelien Jarno1-3/+3
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). Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-12-27pci: fix migration path for devices behind bridgesMichael S. Tsirkin1-11/+37
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 Yamahata2-1/+15
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.

2010-12-19pci: don't use bus number in migration, stub outMichael S. Tsirkin1-1/+4
Using bus numbers in migration is clearly wrong as they are guest assigned.

2010-12-12Watchdog: disable watchdog timer when hard-rebooting a guest.Richard W.M. Jones2-5/+20
This commit causes the watchdog timer to be reset when a guest is hard-rebooted. The failure case previously was as follows: (a) guest boots, watchdog is enabled (b) guest does a reset eg: echo 'b' > /proc/sysrq-trigger (note that an ordinary /sbin/reboot wouldn't hit this case since as the watchdog daemon is shut down, the daemon would properly disable the watchdog device) (c) the reboot takes longer than the remaining time on the watchdog (d) the watchdog therefore fires during the reboot (e) probably the VM would just reboot again at this point which is pretty benign, but it could depend on the action that the user had selected for the watchdog Now we use the qdev reset function to register a reset handler which disables the timer. Note the handler is called _either_ just after init _or_ when the guest reboots. In the i6300esb case there is a small refactoring of the code so that the device's internal state is now fully restored to defaults on a reboot. Signed-off-by: Richard W.M.
