We create optional sections with this patch. But we already have optional subsections. Instead of having two mechanism that do the same, we can just generalize it. For subsections we just change: - Add a needed function to VMStateDescription - Remove VMStateSubsection (after removal of the needed function it is just a VMStateDescription) - Adjust the whole tree, moving the needed function to the corresponding VMStateDescription Signed-off-by: NJuan Quintela <quintela@redhat.com>

Since the BSP bit is writable on real hardware, during reset all the CPUs which were not chosen to be the BSP should have their BSP bit cleared. This fix is required for KVM to work correctly when it changes the BSP bit. An additional fix is required for QEMU tcg to allow software to change the BSP bit.

Right now you only get to apic_init_reset if you have an APIC (do_cpu_init is reached only if CPU_INTERRUPT_INIT is set and that only happens in hw/intc/apic.c). However, this is wrong because for example a port 92 or keyboard controller reset is really an INIT, and that can happen also with no APIC. So keep the check and fix the error that Coverity reported.

In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dade. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

Since 39bffca2 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

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/100806Signed-off-by: NIgor Mammedov <imammedo@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This enables acceleration for MMIO-based TPR registers accesses of 32-bit Windows guest systems. It is mostly useful with KVM enabled, either on older Intel CPUs (without flexpriority feature, can also be manually disabled for testing) or any current AMD processor. The approach introduced here is derived from the original version of qemu-kvm. It was refactored, documented, and extended by support for user space APIC emulation, both with and without KVM acceleration. The VMState format was kept compatible, so was the ABI to the option ROM that implements the guest-side para-virtualized driver service. This enables seamless migration from qemu-kvm to upstream or, one day, between KVM and TCG mode. The basic concept goes like this: - VAPIC PV interface consisting of I/O port 0x7e and (for KVM in-kernel irqchip) a vmcall hypercall is registered - VAPIC option ROM is loaded into guest - option ROM activates TPR MMIO access reporting via port 0x7e - TPR accesses are trapped and patched in the guest to call into option ROM instead, VAPIC support is enabled - option ROM TPR helpers track state in memory and invoke hypercall to poll for pending IRQs if required Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NAvi Kivity <avi@redhat.com>

This will allow the APIC core to file a TPR access report. Depending on the accelerator and kernel irqchip mode, it will either be delivered right away or queued for later reporting. In TCG mode, we can restart the triggering instruction and can therefore forward the event directly. KVM does not allows us to restart, so we postpone the delivery of events recording in the user space APIC until the current instruction is completed. Note that KVM without in-kernel irqchip will report the address after the instruction that triggered the access.

This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
