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: NBlue Swirl <blauwirbel@gmail.com>

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: NBlue Swirl <blauwirbel@gmail.com>

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: NBlue Swirl <blauwirbel@gmail.com>

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.

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.

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: NPeter Maydell <peter.maydell@linaro.org> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

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.

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.

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.

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.
