2013-04-16target-i386: Split out CPU creation and features parsingIgor Mammedov
Move CPU creation and features parsing into a separate cpu_x86_create() function, so that board would be able to set board-specific CPU properties before CPU is realized. Keep cpu_x86_init() for compatibility with the code that uses cpu_init() and doesn't need to modify CPU properties.

2013-04-16target-i386: Split APIC creation from initialization in x86_cpu_realizefn()Igor Mammedov
When APIC is hotplugged during CPU hotplug, device_set_realized() calls device_reset() on it. And if QEMU runs in KVM mode, following call chain will fail: apic_reset_common() -> kvm_apic_vapic_base_update() -> kvm_vcpu_ioctl(cpu->kvm_fd,...) due to cpu->kvm_fd not being initialized yet. cpu->kvm_fd is initialized during qemu_init_vcpu() but x86_cpu_apic_init() can't be moved after it because kvm_init_vcpu() -> kvm_arch_reset_vcpu() relies on APIC to determine if CPU is BSP for setting initial env->mp_state. So split APIC device creation from its initialization and realize APIC after CPU is created, when it's safe to call APIC's reset method.

commit 5ec01c2e96910e1588d1a0de8609b9dda7618c7f broke "-cpu ..,enforce", as it has moved kvm_check_features_against_host() after the filter_features_for_kvm() call. filter_features_for_kvm() removes all features not supported by the host, so this effectively made kvm_check_features_against_host() impossible to fail.

2013-02-27Fix guest OS hang when 64bit PCI bar presentAlexey Korolev
This patch addresses the issue fully described here: http://lists.nongnu.org/archive/html/qemu-devel/2013-02/msg01804.html Linux kernels prior to 2.6.36 do not disable the PCI device during enumeration process. Since lower and higher parts of a 64bit BAR are programmed separately this leads to qemu receiving a request to occupy a completely wrong address region for a short period of time. We have found that the boot process screws up completely if kvm-apic range is overlapped even for a short period of time (it is fine for other regions though). This patch raises the priority of the kvm-apic memory region, so it is never pushed out by PCI devices. The patch is quite safe as it does not touch memory manager.

So there is no need to overwrite tsc_khz with default 0 because field was already initialized to 0. Custom tsc-frequency setting is not affected due to it being set without using x86_def_t.

2013-01-27target-i386: Set custom features/properties without intermediate x86_def_tIgor Mammedov
Move custom features parsing after built-in cpu_model defaults are set and set custom features directly on CPU instance. That allows to make a clear distinction between built-in cpu model defaults that eventually should go into class_init() and extra property setting which is done after defaults are set on CPU instance. Impl. details: * use object_property_parse() property setter so it would be a mechanical change to switch to global properties later. * And after all current features/properties are converted into static properties, it will take a trivial patch to switch to global properties. Which will allow to: * get CPU instance initialized with all parameters passed on -cpu ... cmd. line from object_new() call. * call cpu_model/featurestr parsing only once before CPUs are created * open a road for removing CPUxxxState.cpu_model_str field, when other CPUs are similarly converted to subclasses and static properties. - re-factor error handling, to use Error instead of fprintf()s, since it is anyway passed in for property setter.

2013-01-27target-i386: Remove vendor_override field from CPUX86StateIgor Mammedov
Commit 8935499831312 makes cpuid return to guest host's vendor value instead of built-in one by default if kvm_enabled() == true and allows to override this behavior if 'vendor' is specified on -cpu command line. But every time guest calls cpuid to get 'vendor' value, host's value is read again and again in default case. It complicates semantics of vendor property and makes it harder to use. Instead of reading 'vendor' value from host every time cpuid[vendor] is called, override 'vendor' value only once in cpu_x86_find_by_name(), when built-in CPU model is found and if(kvm_enabled() == true). It provides the same default semantics if (kvm_enabled() == true) vendor = host's vendor else vendor = built-in vendor and then later: if (custom vendor) vendor = custom vendor 'vendor' value is overridden when user provides it on -cpu command line, and there is no need for vendor_override field anymore, remove it.

2013-01-27target-i386: Replace uint32_t vendor fields by vendor string in x86_def_tIgor Mammedov
Vendor property setter takes string as vendor value but cpudefs use uint32_t vendor[123] fields to define vendor value. It makes it difficult to unify and use property setter for values from cpudefs. Simplify code by using vendor property setter, vendor[123] fields are converted into vendor[13] array to keep its value. And vendor property setter is used to access/set value on CPU. - Make for() cycle reusable for the next patch by adding x86_cpu_vendor_words2str() Intel's CPUID spec[1] says: " 5.1.1 ... These registers contain the ASCII string: GenuineIntel ... " List[2] of known vendor values shows that they all are 12 ASCII characters long, padded where necessary with space.

2013-01-27pc: Reverse pc_init_pci() compatibility logicEduardo Habkost
Currently, the pc-1.4 machine init function enables PV EOI and then calls the pc-1.2 machine init function. The problem with this approach is that now we can't enable any additional compatibility code inside the pc-1.2 init function because it would end up enabling the compatibility behavior on pc-1.3 and pc-1.4 as well. This reverses the logic so that the pc-1.2 machine init function will disable PV EOI, and then call the pc-1.4 machine init function. This way we can change older machine-types to enable compatibility behavior, and the newer machine-types (pc-1.3, pc-q35-1.4 and pc-i440fx-1.4) would just use the default behavior. (This means that one nice side-effect of this change is that pc-q35-1.4 will get PV EOI enabled by default, too) It would be interesting to eventually change pc_init_pci_no_kvmclock() and pc_init_isa() to reuse pc_init_pci_1_2() as well (so we don't need to duplicate compatibility code on those two functions). But this will be probably much easier to do after we create a PCInitArgs struct for the PC initialization arguments, and/or after we use global-properties to implement the compatibility modes present in pc_init_pci_1_2().

2013-01-27target-i386: Don't set any KVM flag by default if KVM is disabledEduardo Habkost
This is a cleanup that tries to solve two small issues: - We don't need a separate kvm_pv_eoi_features variable just to keep a constant calculated at compile-time, and this style would require adding a separate variable (that's declared twice because of the CONFIG_KVM ifdef) for each feature that's going to be enabled/disabled by machine-type compat code. - The pc-1.3 code is setting the kvm_pv_eoi flag on cpuid_kvm_features even when KVM is disabled at runtime. This small inconsistency in the cpuid_kvm_features field isn't a problem today because cpuid_kvm_features is ignored by the TCG code, but it may cause unexpected problems later when refactoring the CPUID handling code. This patch eliminates the kvm_pv_eoi_features variable and simply uses kvm_enabled() inside the enable_kvm_pv_eoi() compat function, so it enables kvm_pv_eoi only if KVM is enabled. I believe this makes the behavior of enable_kvm_pv_eoi() clearer and easier to understand.

It doesn't make sense to keep it enabled by default, as it would cause unnecessary hassle when using the "enforce" flag. This disables kvm_mmu on all machine-types.
