2015-10-02cpu/apic: drop icc bus/bridgeChen Fan
After CPU hotplug has been converted to BUS-less hot-plug infrastructure, the only function ICC bus performs is to propagate reset to LAPICs. However LAPIC could be reset by registering its reset handler after all device are initialized. Do so and drop ~30LOC of not needed anymore ICCBus related code.

2015-10-02Correctly re-init EFER state during INIT IPIBill Paul
When doing a re-initialization of a CPU core, the default state is to _not_ have 64-bit long mode enabled. This means the LME (long mode enable) and LMA (long mode active) bits in the EFER model-specific register should be cleared. However, the EFER state is part of the CPU environment which is preserved by do_cpu_init(), so if EFER.LME and EFER.LMA were set at the time an INIT IPI was received, they will remain set after the init completes. This is contrary to what the Intel architecture manual describes and what happens on real hardware, and it leaves the CPU in a weird state that the guest can't clear. To fix this, the 'efer' member of the CPUX86State structure has been moved to an area outside the region preserved by do_cpu_init(), so that it can be properly re-initialized by x86_cpu_reset().

2015-10-02target-i386: add ABM to Haswell* and Broadwell* CPU modelsPaolo Bonzini
ABM is only implemented as a single instruction set by AMD; all AMD processors support both instructions or neither. Intel considers POPCNT as part of SSE4.2, and LZCNT as part of BMI1, but Intel also uses AMD's ABM flag to indicate support for both POPCNT and LZCNT. It has to be added to Haswell and Broadwell because Haswell, by adding LZCNT, has completed the ABM. Tested with "qemu-kvm -cpu Haswell-noTSX,enforce" (and also with older machine types) on an Haswell-EP machine.

W10 insider has a bug where it ignores CPUID level and interprets CPUID.(EAX=07H, ECX=0H) incorrectly, because CPUID in fact returned CPUID.(EAX=04H, ECX=0H); this resulted in execution of unsupported instructions. While it's a Windows bug, there is no reason to emulate incorrect level.

2015-07-09translate-all: Change tb_flush() env argument to cpuPeter Crosthwaite
All of the core-code usages of this API have the cpu pointer handy so pass it in. There are only 3 architecture specific usages (2 of which are commented out) which can just use ENV_GET_CPU() locally to get the cpu pointer. The reduces core code usage of the CPU env, which brings us closer to common-obj'ing these core files.

2015-07-09cpu: Add Error argument to cpu_exec_init()Bharata B Rao
Add an Error argument to cpu_exec_init() to let users collect the error. This is in preparation to change the CPU enumeration logic in cpu_exec_init(). With the new enumeration logic, cpu_exec_init() can fail if cpu_index values corresponding to max_cpus have already been handed out. Since all current callers of cpu_exec_init() are from instance_init, use error_abort Error argument to abort in case of an error.

2015-07-07target-i386: avoid overflow in the tsc-frequency propertyPaolo Bonzini
The TSC frequency fits comfortably in an int when expressed in kHz, but it may overflow when converted to Hz. In this case, tsc-frequency returns a negative value because x86_cpuid_get_tsc_freq does a 32-bit multiplication before assigning to int64_t. For simplicity just make tsc_khz a 64-bit value.

2015-07-07i386: Introduce ARAT CPU featureJan Kiszka
ARAT signals that the APIC timer does not stop in power saving states. As our APICs are emulated, it's fine to expose this feature to guests, at least when asking for KVM host features or with CPU types that include the flag. The exact model number that introduced the feature is not known, but reports can be found that it's at least available since Sandy Bridge.
