2010-04-28virtio-serial: save/load: Send target host connection status if differentAmit Shah1-0/+11
If the host connection to a port is closed on the destination machine after migration, whereas the connection was open on the source, the guest has to be informed of that. Similar for a host connection open on the destination. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-28virtio-serial: save/load: Ensure we have hot-plugged ports instantiatedAmit Shah1-0/+7
If some ports that were hot-plugged on the source are not available on the destination, fail migration instead of trying to deref a NULL pointer. Signed-off-by: Amit Shah <amit.shah@redhat.com> Reported-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-28virtio-serial: save/load: Ensure nr_ports on src and dest are same.Amit Shah1-2/+16
The number of ports on the source as well as the destination machines should match. If they don't, it means some ports that got hotplugged on the source aren't instantiated on the destination. Or that ports that were hot-unplugged on the source are created on the destination.

2010-04-28virtio-serial: save/load: Ensure target has enough portsAmit Shah1-2/+11
The target could be started with max_nr_ports for a virtio-serial device lesser than what was available on the source machine. Fail the migration in such a case.

2010-04-27microblaze: fix custom fprintfThomas Monjalon1-31/+31
Using GCC-4.2.4-1ubuntu4, there is a warning: microblaze-dis.c:792: warning: unused variable 'fprintf' Indeed, fprintf() is shadowed by a custom redefinition but is not used because of FORTIFY_SOURCE option which replace calls to fprintf() by fprintf_chk(). So, fprintf refers to the libc implementation instead of the qemu one. It's a bug. It is fixed by renaming the variable to something different of "fprintf". It prevents from hazardous shadowing.

2010-04-27target-alpha: Implement RPCC.Richard Henderson2-3/+3
A minimal implementation that more or less corresponds to the user-level version used by target-i386. More hoops will want to be jumped through when alpha gets system-level emulation. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-27target-alpha: Fix load-locked/store-conditional.Richard Henderson5-79/+193

When (indirectly) calling raise_exception, don't emit cleanup code at the end of the TB, as it is unused. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-04-27target-alpha: Implement rs/rc properly.Richard Henderson4-33/+23
This is a per-cpu flag; there's no need for a spinlock of any kind. We were also failing to manipulate the flag with $31 as a target reg and failing to clear the flag on execution of a return-from-interrupt instruction.

2010-04-26stash away SCM_RIGHTS fd until a getfd command arrivesPaolo Bonzini2-15/+3
If there is already a fd in s->msgfd before recvmsg it is closed by parts that this patch does not touch. So, only one descriptor can be "leaked" by attaching it to a command other than getfd. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2010-04-26monitor: Reorder intialization to drop initial mux focusJan Kiszka1-3/+4
So far a multiplexed monitor started disabled. Restore this property for the new way of configuring by moving the monitor initialization before all devices (the last one to attach to a char-mux will gain the focus). Once we have a real use case for that, we may also consider assigning the initial focus explicitly.

2010-04-26Monitor: Return before exiting with 'quit'Luiz Capitulino3-1/+22
The 'quit' Monitor command (implemented by do_quit()) calls exit() directly, this is problematic under QMP because QEMU exits before having a chance to send the ok response. Clients don't know if QEMU exited because of a problem or because the 'quit' command has been executed. This commit fixes that by moving the exit() call to the main loop, so that do_quit() requests the system to quit, instead of calling exit() directly.

2010-04-26tcg-hppa: Fix softmmu loads and stores.Richard Henderson1-144/+132
Along the tlb hit path, we were modifying the variables holding the input register numbers, which lead to incorrect expansion of the tlb miss path. Fix this by extracting the tlb hit path to separate functions with their own local variables. This also makes the difference between softmmu and user-only easier to read.

2010-04-26target-sparc: Fix -singlestep.Richard Henderson1-4/+5
Single-stepping was not properly updating npc, resulting in some instructions being executed twice. In addition, we were emitting dead code at the end of the TB.

The ABI-specific types used by linux_binprm and image_info are different after forcing TARGET_ABI32 on.
