2011-06-26Remove exec-all.h include directivesBlue Swirl
Most exec-all.h include directives are now useless, remove them. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26Move cpu_has_work and cpu_pc_from_tb to cpu.hBlue Swirl
Move functions cpu_has_work() and cpu_pc_from_tb() from exec.h to cpu.h. This is needed by later patches. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26exec.h: fix coding style and change cpu_has_work to return boolBlue Swirl
Before the next patch, fix coding style of the areas affected. Change the type of the return value from cpu_has_work() and qemu_cpu_has_work() to bool. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26cpu-exec: unify do_interrupt callBlue Swirl
Now that all targets use common function signature for do_interrupt(), there is no need for the #ifdeffery anymore. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26m68k: use caller supplied CPUState for interrupt related stuffBlue Swirl
Pass CPUState to do_interrupt(). This is needed by later patches. It would be cleaner to move the function to helper.c, but there are a few dependencies between do_interrupt() and other functions. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26x86: use caller supplied CPUState for interrupt related stuffBlue Swirl
Several x86 specific functions are called from cpu-exec.c with the assumption that global env register is valid. This will be changed later, so make the functions use caller supplied CPUState parameter. It would be cleaner to move the functions to helper.c, but there are quite a lot of dependencies between do_interrupt() and other functions. Add helpers for svm_check_intercept() and cpu_cc_compute_all() instead of calling the helper (which uses global env, AREG0) directly. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26sparc: move do_interrupt to helper.cBlue Swirl
do_interrupt() was mixing CPUState pointer passed from caller and global env (AREG0). Fix by moving the function to helper.c. Introduce a helper for calling change_pstate() safely from outside of execution context. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-06-26cpu_loop_exit: avoid using AREG0Blue Swirl

2011-06-26Sparc32: dummy implementation of MXCC MMU breakpoint registersBlue Swirl

2011-06-26Fix fallouts from Linux header inclusionJan Kiszka
This is an all-in-one fix for the smaller and bigger mistakes of the build system changes for accompanied Linux headers: - only enable KVM and vhost on Linux hosts - fix powerpc asm header symlink - do not use Linux headers on non-Linux hosts - fix kvmclock for !CONFIG_KVM - fix s390 build on non-Linux hosts Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Tested-by: Andreas Färber <andreas.faerber@web.de> Tested-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-23coreaudio: Fix OSStatus format specifierAndreas Färber
OSStatus type is defined as SInt32. That's signed int on __LP64__ and signed long otherwise. Since it is an explicit 32-bit-width type, cast to corresponsing POSIX type and use PRId32 format specifier. This avoids a warning on ppc64.

2011-06-23coreaudio: Avoid formatting UInt32 typeAndreas Färber
coreaudioVoiceOut's audioDevicePropertyBufferFrameSize is defined as UInt32 and is being used by reference for AudioDevice{Get,Set}Property(). UInt32 is unsigned int on __LP64__ but unsigned long otherwise. Cast to POSIX type and use PRIu32 format specifier to hide the details. This avoids a warning on ppc64.

2011-06-22net: Warn about "-net nic" options which were ignoredPeter Maydell
Diagnose the case where the user asked for a NIC via "-net nic" but the board didn't instantiate that NIC (for example where the user asked for two NICs but the board only supports one). Note that this diagnostic doesn't apply to NICs created through -device, because those are always instantiated.

2011-06-22net: Don't warn about the default network setupPeter Maydell
Don't warn about the default network setup that you get if no command line -net options are specified. There are two cases that we would otherwise complain about: (1) board doesn't support a NIC but the implicit "-net nic" requested one (2) CONFIG_SLIRP not set, so the implicit "-net nic" sets up a nic that isn't connected to anything Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-06-22Revert "net: Improve the warnings for dubious command line option combinations"Peter Maydell
This reverts commit f68b9d672b90dedc79aeb9b44607f484dbe46a6b. That attempt at diagnosing unused -net nic options failed to account for NICs created via -device; back it out cleanly in preparation for implementing in a different manner.

2011-06-22Optimize screendumpAvi Kivity
When running kvm-autotest, fputc() is often the second highest (sometimes #1) function showing up in a profile. This is due to fputc() locking the file for every byte written. Optimize by buffering a line's worth of pixels and writing that out in a single call.

2011-06-20KVM: Fix XSAVE feature bit enumerationAndre Przywara
When iterating through the XSAVE feature enumeration CPUID leaf (0xD) we should not stop at the first zero EAX, but instead keep scanning since there are gaps in the enumeration (ECX=1 for instance).

2011-06-20Switch build system to accompanied kernel headersJan Kiszka
This helps reducing our build-time checks for feature support in the available Linux kernel headers. And it helps users that do not have sufficiently recent headers installed on their build machine. Consequently, the patch removes and build-time checks for kvm and vhost in configure, the --kerneldir switch, and KVM_CFLAGS. Kernel headers are supposed to be provided by QEMU only. s390 needs some extra love as it carries redefinitions from kernel headers.

2011-06-19kvm: x86: Save/restore FPU OP, IP and DPJan Kiszka
These FPU states are properly maintained by KVM but not yet by TCG. So far we unconditionally set them to 0 in the guest which may cause state corruptions, though not with modern guests. To avoid breaking backward migration, use a conditional subsection that is only written if any of the three fields is non-zero. The guest's FNINIT clears them frequently, and cleared IA32_MISC_ENABLE MSR[2] reduces the probability of non-zero values further so that this subsection is not expected to restrict migration in any common scenario.

2011-06-19xen: mapcache performance improvementsStefano Stabellini
Use qemu_invalidate_entry in cpu_physical_memory_unmap. Do not lock mapcache entries in qemu_get_ram_ptr if the address falls in the ramblock with offset == 0. We don't need to do that because the callers of qemu_get_ram_ptr either try to map an entire block, other from the main ramblock, or until the end of a page to implement a single read or write in the main ramblock. If we don't lock mapcache entries in qemu_get_ram_ptr we don't need to call qemu_invalidate_entry in qemu_put_ram_ptr anymore because we can leave with few long lived block mappings requested by devices. Also move the call to qemu_ram_addr_from_mapcache at the beginning of qemu_ram_addr_from_host.

2011-06-19exec.c: refactor cpu_physical_memory_mapStefano Stabellini
Introduce qemu_ram_ptr_length that takes an address and a size as parameters rather than just an address. Refactor cpu_physical_memory_map so that we call qemu_ram_ptr_length only once rather than calling qemu_get_ram_ptr one time per page. This is not only more efficient but also tries to simplify the logic of the function. Currently we are relying on the fact that all the pages are mapped contiguously in qemu's address space: we have a check to make sure that the virtual address returned by qemu_get_ram_ptr from the second call on is consecutive. Now we are making this more explicit replacing all the calls to qemu_get_ram_ptr with a single call to qemu_ram_ptr_length passing a size argument.

The new implementation supports locked mapcache entries with size multiple of MCACHE_BUCKET_SIZE. qemu_invalidate_entry can correctly find and unmap these "large" mapcache entries given that the virtual address passed to qemu_invalidate_entry is the same returned by qemu_map_cache when the locked mapcache entry was created.
