Move softmmu_exec.h include directives from target-*/exec.h to target-*/op_helper.c. Move also various other stuff only used in op_helper.c there. Define global env in dyngen-exec.h. For i386, move wrappers for segment and FPU helpers from user-exec.c to op_helper.c. Implement raise_exception_err_env() to handle dynamic CPUState. Move the function declarations to cpu.h since they can be used outside of op_helper.c context. LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and env_to_regs(). ARM: make raise_exception() static. Convert #include "exec.h" to #include "cpu.h" #include "dyngen-exec.h" and remove now unused target-*/exec.h. 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>

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.

If the machine is stopped, we should not record two different tsc values upon a save operation. The same problem happens with kvmclock. But kvmclock is taking a different diretion, being now seen as a separate device. Since this is unlikely to happen with the tsc, I am taking the approach here of simply registering a handler for state change, and using a per-CPUState variable that prevents double updates for the TSC.

Port qemu-kvm's commit 4b62fff1101a7ad77553147717a8bd3bf79df7ef Author: Huang Ying <ying.huang@intel.com> Date: Mon Sep 21 10:43:25 2009 +0800 MCE: Relay UCR MCE to guest UCR (uncorrected recovery) MCE is supported in recent Intel CPUs, where some hardware error such as some memory error can be reported without PCC (processor context corrupted). To recover from such MCE, the corresponding memory will be unmapped, and all processes accessing the memory will be killed via SIGBUS. For KVM, if QEMU/KVM is killed, all guest processes will be killed too. So we relay SIGBUS from host OS to guest system via a UCR MCE injection. Then guest OS can isolate corresponding memory and kill necessary guest processes only. SIGBUS sent to main thread (not VCPU threads) will be broadcast to all VCPU threads as UCR MCE. aliguori: fix build Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com> Signed-off-by: NAvi Kivity <avi@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This is a reimplementation of prior versions which adds the ability to define cpu models for contemporary processors. The added models are likewise selected via -cpu <name>, and are intended to displace the existing convention of "-cpu qemu64" augmented with a series of feature flags. A primary motivation was determination of a least common denominator within a given processor class to simplify guest migration. It is still possible to modify an arbitrary model via additional feature flags however the goal here was to make doing so unnecessary in typical usage. The other consideration was providing models names reflective of current processors. Both AMD and Intel have reviewed the models in terms of balancing generality of migration vs. excessive feature downgrade relative to released silicon. This version of the patch replaces the prior hard wired definitions with a configuration file approach for new models. Existing models are thus far left as-is but may easily be transitioned to (or may be overridden by) the configuration file representation. Proposed new model definitions are provided here for current AMD and Intel processors. Each model consists of a name used to select it on the command line (-cpu <name>), and a model_id which corresponds to a least common denominator commercial instance of the processor class. A table of names/model_ids may be queried via "-cpu ?model": : x86 Opteron_G3 AMD Opteron 23xx (Gen 3 Class Opteron) x86 Opteron_G2 AMD Opteron 22xx (Gen 2 Class Opteron) x86 Opteron_G1 AMD Opteron 240 (Gen 1 Class Opteron) x86 Nehalem Intel Core i7 9xx (Nehalem Class Core i7) x86 Penryn Intel Core 2 Duo P9xxx (Penryn Class Core 2) x86 Conroe Intel Celeron_4x0 (Conroe/Merom Class Core 2) : Also added is "-cpu ?dump" which exhaustively outputs all config data for all defined models, and "-cpu ?cpuid" which enumerates all qemu recognized CPUID feature flags. The pseudo cpuid flag 'check' when added to the feature flag list will warn when feature flags (either implicit in a cpu model or explicit on the command line) would have otherwise been quietly unavailable to a guest: # qemu-system-x86_64 ... -cpu Nehalem,check warning: host cpuid 0000_0001 lacks requested flag 'sse4.2|sse4_2' [0x00100000] warning: host cpuid 0000_0001 lacks requested flag 'popcnt' [0x00800000] A similar 'enforce' pseudo flag exists which in addition to the above causes qemu to error exit if requested flags are unavailable. Configuration data for a cpu model resides in the target config file which by default will be installed as: /usr/local/etc/qemu/target-<arch>.conf The format of this file should be self explanatory given the definitions for the above six models and essentially mimics the structure of the static x86_def_t x86_defs. Encoding of cpuid flags names now allows aliases for both the configuration file and the command line which reconciles some Intel/AMD/Linux/Qemu naming differences. This patch was tested relative to qemu.git. Signed-off-by: Njohn cooper <john.cooper@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
