2009-12-18monitor: Use 'device' in ejectLuiz Capitulino
Monitor's eject command uses 'filename' for the device name argument, but 'device' is a better name. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-12-18Avoid permanently disabled QEMU monitor when UNIX migration failsDaniel P. Berrange
If a UNIX migration command is attempt to a UNIX socket which does not exist, then the monitor is suspended, but never resumed. This prevents any further use of the monitor * migration-unix.c: Only call migrate_fd_monitor_suspend() once connected to the UNIX socket. Signed-off-by: Daniel P.

2009-12-18Fix loading of ELF multiboot kernelsKevin Wolf
The multiboot implementation assumed that there is only one program header (which contains the entry point) and that the entry point is at the start of the code. This doesn't hold true generally and caused too little data to be loaded. Fix the loading code to pass the whole loaded data to the Multiboot Option ROM.

2009-12-18Revert "Rename DriveInfo.onerror to on_write_error" (fix mismerge)Kevin Wolf
Part of the first patch of the -drive rerror series has been merged once more on top of the rest of the series. This effectively disables the rerror option and always goes with the default value. Reverting the commit re-enables the option. This reverts commit fc072ec4df0996682dfbff6c735e2bbc0d93132f.

2009-12-18target-i386: Fix evaluation of DR7 registerJan Kiszka
hw_breakpoint_type and hw_breakpoint_len used the wrong index multiplier to extract type and len. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-18kvm: x86: Use separate exception_injected CPUState fieldJan Kiszka
Marcelo correctly remarked that there are usage conflicts between QEMU core code and KVM /wrt exception_index. So spend a separate field and also save/restore it properly. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-18vnc: hextile: do not generate ForegroundSpecified and SubrectsColoured tilesAnthony Liguori

2009-12-18S390: Bail out without KVMAlexander Graf
Currently only the S390 KVM target works. To keep users from accidently not using KVM, let's not even initialize the machine when KVM is not used. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-18S390: Don't tell guest we're updating config spaceAlexander Graf
Currently we always set the "config space changed" bit to 1 when triggering any virtio interrupt. While that worked in 2.6.27, newer kernels interpret that value as "only the config space changed and nothing else happened". Since we usually trigger interrupts to tell the guest that something did happen, we just not tell it the config space changed for now until we implement the correct callback for that.

2009-12-18add default virtcon initializationAlexander Graf
When going through the default devices, we don't initialize the virtio console, unless we're doing -nographic. I suppose that's just a leftover from the recent code restructuring, so let's put it in. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-18S390: Loop through virtio console devicesAlexander Graf
We used to always create one single virtio console device. This breaks when either zero of multiple virtio console devices are requested, so let's use the same code as on x86. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-18target-s390: Fail on unknown instructionsAlexander Graf
We were being a bit too nice and didn't give the guest an invalid instruction interrupt. While that works, it's not exactly the fastest thing to do, since now the guest doesn't know that we're not really implementing that instruction, so it continues doing it. We run into this with the set_page_unstable hint instruction. So let's bail out in these cases. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-18osdep: Fix runtime failure on older Linux kernelsAndre Przywara
If QEMU finds newer kernel header files on compilation time, it will use advertised features like pipe2 or SOCK_CLOEXEC by just doing a compile test. If later the executables are executed on an older kernel (<2.6.27, like Xen Dom0 2.6.18), then QEMU will fail on opening sockets and creating pipes and returns the rather unspecific "qemu_init_main_loop failed". This patch fixes this by checking the return values of these calls for EINVAL and ENOSYS and falling back to the older versions automatically.

2009-12-17Fix a make -j raceJuergen Lock
Make libuser.a depend on $(GENERATED_HEADERS) too so make -j won't start building it before the headers exist. (There may be more bugs like this but at least this makes (g)make -j4 started from scratch on a quadcore now always complete here again.)

2009-12-17target-alpha: Fix float32_to_s vs zero exponent.Richard Henderson
There was a bug in float32_to_s that incorrectly mapped a zero exponent to 0x38. This meant 0.0f != 0. At the same time, fix a generic type punning bug in helper_memory_to_s and helper_s_to_memory.

2009-12-17target-alpha: Implement fp branch/cmov inline.Richard Henderson
The old fcmov implementation had a typo: - tcg_gen_mov_i64(cpu_fir[rc], cpu_fir[ra]); which moved the condition, not the second source, to the destination.

2009-12-13target-mips: fix user-mode emulation startupNathan Froyd
Running programs with the MIPS user-mode emulator fails during dynamic loading, as floating-point instructions are not enabled in in env->hflags. Move the code for doing so from fpu_init to cpu_reset so the MIPS_HFLAG_{FPU,F64} setting doesn't get clobbered by cpu_reset setting env->hflags to MIPS_HFLAG_UM. The same end can be achieved by swapping the ordering of fpu_init and cpu_reset in cpu_mips_init, but it seemed better to consolidate the CONFIG_USER_ONLY code into a single location.

2009-12-13target-alpha: Fixes for alpha-linux syscalls.Richard Henderson
1. Add correct definitions of error numbers. 2. Implement SYS_osf_sigprocmask 3. Implement SYS_osf_get/setsysinfo for IEEE_FP_CONTROL. This last requires exposing the FPCR value to do_syscall. Since this value is actually split up into the float_status, expose routines from helper.c to access it. Finally, also add a float_exception_mask field to float_status. We don't actually use it to control delivery of exceptions to the emulator yet, but simply hold the value that we placed there when loading/storing the FPCR.
