2012-08-01target-i386: move cpu_reset and reset callback to cpu.cIgor Mammedov1-0/+14
Moving reset callback into cpu object from board level and resetting cpu at the end of x86_cpu_realize() will allow properly create cpu object during run-time (hotplug) without calling reset externaly. When reset over QOM hierarchy is implemented, reset callback should be removed. v2: - leave cpu_reset in pc_new_cpu() for now, it's to be cleaned up when APIC init is moved in cpu.c Signed-off-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-08-01target-i386: move cpu halted decision into x86_cpu_resetIgor Mammedov3-2/+19
MP initialization protocol differs between cpu families, and for P6 and onward models it is up to CPU to decide if it will be BSP using this protocol, so try to model this. However there is no point in implementing MP initialization protocol in qemu. Thus first CPU is always marked as BSP. This patch: - moves decision to designate BSP from board into cpu, making cpu self-sufficient in this regard. Later it will allow to cleanup hw/pc.c and remove cpu_reset and wrappers from there. - stores flag that CPU is BSP in IA32_APIC_BASE to model behavior described in Inted SDM vol 3a part 1 chapter 8.4.1 - uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP patch is based on Jan Kiszka's proposal: http://thread.gmane.org/gmane.comp.emulators.qemu/100806 Signed-off-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-07-29x86: Fixed incorrect segment base address addition in 64-bits modeVitaly Chipounov1-18/+25
According to the Intel manual "Intel® 64 and IA-32 Architectures Software Developer’s Manual Volume 3", "3.4.4 Segment Loading Instructions in IA-32e Mode": "When in compatibility mode, FS and GS overrides operate as defined by 32-bit mode behavior regardless of the value loaded into the upper 32 linear-address bits of the hidden descriptor register base field. Compatibility mode ignores the upper 32 bits when calculating an effective address." However, the code misses the 64-bit mode case, where an instruction with address and segment size override would be translated incorrectly. For example, inc dword ptr gs:260h[ebx*4] gets incorrectly translated to: (uint32_t)(gs.base + ebx * 4 + 0x260) instead of gs.base + (uint32_t)(ebx * 4 + 0x260) Signed-off-by: Vitaly Chipounov <vitaly.chipounov@epfl.ch> Reviewed-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-07-10apic: Defer interrupt updates to VCPU threadJan Kiszka2-1/+7
KVM performs TPR raising asynchronously to QEMU, specifically outside QEMU's global lock. When an interrupt is injected into the APIC and TPR is checked to decide if this can be delivered, a stale TPR value may be used, causing spurious interrupts in the end. Fix this by deferring apic_update_irq to the context of the target VCPU. We introduce a new interrupt flag for this, CPU_INTERRUPT_POLL. When it is set, the VCPU calls apic_poll_irq before checking for further pending interrupts. To avoid special-casing KVM, we also implement this logic for TCG mode.

The X86_64_DEF macro is a confusing way of making some terms in a conditional only appear if TARGET_X86_64 is defined. We only use it in two places, and in both cases this is for making the same test, so abstract that check out into a function where we can use a more conventional #ifdef.

commit c4baa0503d9623f1ce891f525ccd140c598bc29a improved SSE table type safety which now raises compiler errors when latest QEMU was configured with --enable-debug. Fix this by splitting the SSE tables even further to separate helper functions with different signatures. Instead of crashing by calling address 0, the code now jumps to label illegal_op.
