| | | | | | | | | | | | | | | | | | | | | | | | | Export various helper variables describing the layout and size of certain kernel structures for use by debuggers. This mostly aids in examining cores from a kernel without debug symbols as a debugger can infer these values if debug symbols are available. One set of variables describes the layout of 'struct linker_file' to walk the list of loaded kernel modules. A second set of variables describes the layout of 'struct proc' and 'struct thread' to walk the list of processes in the kernel and the threads in each process. The 'pcb_size' variable is used to index into the stoppcbs[] array. The 'vm_maxuser_address' is used to distinguish kernel virtual addresses from user addresses. This doesn't have to be perfect, and 'vm_maxuser_address' is a cheap and simple way to differentiate kernel pointers from simple values like TIDs and PIDs. While here, annotate the fields in struct pcb used by kgdb on amd64 and i386 to note that their ABI should be preserved. Annotations for other platforms will be added in the future.

Use the host capabilities field and not the negotiated field when verifying that indirect descriptors are supported. MFC r282788: Allow configuration of the sector size advertised to the guest. MFC r282865: Set the subvendor field in config space to the vendor ID. This is required by the Windows virtio drivers to correctly match a device.

| | | | | | | | | | | | | | | | | | | | | | Add support for managing PCI bus numbers. As with BARs and PCI-PCI bridge I/O windows, the default is to preserve the firmware-assigned resources. PCI bus numbers are only managed if NEW_PCIB is enabled and the architecture defines a PCI_RES_BUS resource type. - Add a helper API to create top-level PCI bus resource managers for each PCI domain/segment. Host-PCI bridge drivers use this API to allocate bus numbers from their associated domain. - Change the PCI bus and CardBus drivers to allocate a bus resource for their bus number from the parent PCI bridge device. - Change the PCI-PCI and PCI-CardBus bridge drivers to allocate the full range of bus numbers from secbus to subbus from their parent bridge. The drivers also always program their primary bus register. The bridge drivers also support growing their bus range by extending the bus resource and updating subbus to match the larger range. - Add support for managing PCI bus resources to the Host-PCI bridge drivers used for amd64 and i386 (acpi_pcib, mptable_pcib, legacy_pcib, and qpi_pcib). - Define a PCI_RES_BUS resource type for amd64 and i386.

Export the vendor ID and the highest supported hypervisor CPUID leaf via hv_vendor[] and hv_high variables, respectively. The hv_vendor[] array is also exported via the hw.hv_vendor sysctl. - Merge the VMWare detection code from tsc.c into the new probe in identcpu.c.

MFC r270434 Return the spurious interrupt vector (IRQ7 or IRQ15) if the atpic cannot find any unmasked pin with an interrupt asserted. MFC r270436 Fix a bug in the emulation of CPUID leaf 0x4. MFC r270437 Add "hw.vmm.topology.threads_per_core" and "hw.vmm.topology.cores_per_package" tunables to modify the default cpu topology advertised by bhyve. MFC r270855 Set the 'inst_length' to '0' early on before any error conditions are detected in the emulation of the task switch. If any exceptions are triggered then the guest %rip should point to instruction that caused the task switch as opposed to the one after it. MFC r270857 The "SUB" instruction used in getcc() actually does 'x -= y' so use the proper constraint for 'x'. The "+r" constraint indicates that 'x' is an input and output register operand. While here generate code for different variants of getcc() using a macro GETCC(sz) where 'sz' indicates the operand size. Update the status bits in %rflags when emulating AND and OR opcodes. MFC r271439 Initialize 'bc_rdonly' to the right value. MFC r271451 Optimize the common case of injecting an interrupt into a vcpu after a HLT by explicitly moving it out of the interrupt shadow. MFC r271888 Restructure the MSR handling so it is entirely handled by processor-specific code. MFC r271890 MSR_KGSBASE is no longer saved and restored from the guest MSR save area. This behavior was changed in r271888 so update the comment block to reflect this. MFC r271891 Add some more KTR events to help debugging. MFC r272197 mmap(2) requires either MAP_PRIVATE or MAP_SHARED for non-anonymous mappings. MFC r272395 Get rid of code that dealt with the hardware not being able to save/restore the PAT MSR on guest exit/entry. This workaround was done for a beta release of VMware Fusion 5 but is no longer needed in later versions. All Intel CPUs since Nehalem have supported saving and restoring MSR_PAT in the VM exit and entry controls. MFC r272670 Inject #UD into the guest when it executes either 'MONITOR' or 'MWAIT'. MFC r272710 Implement the FLUSH operation in the virtio-block emulation. MFC r272838 iasl(8) expects integer fields in data tables to be specified as hexadecimal values. Therefore the bit width of the "PM Timer Block" was actually being interpreted as 50-bits instead of the expected 32-bit. This eliminates an error message emitted by a Linux 3.17 guest during boot: "Invalid length for FADT/PmTimerBlock: 50, using default 32" MFC r272839 Support Intel-specific MSRs that are accessed when booting up a linux in bhyve: - MSR_PLATFORM_INFO - MSR_TURBO_RATIO_LIMITx - MSR_RAPL_POWER_UNIT MFC r273108 Emulate "POP r/m". This is needed to boot OpenBSD/i386 MP kernel in bhyve. MFC r273212 Support stopping and restarting the AHCI command list via toggling PxCMD.ST from '1' to '0' and back.

| | | | | | | | | | | | Add an ioctl to suspend a virtual machine (VM_SUSPEND). Add logic in the HLT exit handler to detect if the guest has put all vcpus to sleep permanently by executing a HLT with interrupts disabled. When this condition is detected the guest with be suspended with a reason of VM_SUSPEND_HALT and the bhyve(8) process will exit. This logic can be disabled via the tunable 'hw.vmm.halt_detection'.

| | | | | | | | | | | Various x2APIC fixes and enhancements: - Use spinlocks for the vioapic. - Handle the SELF_IPI MSR. - Simplify the APIC mode switching between MMIO and x2APIC. The guest is no longer allowed to switch modes at runtime. Instead, the desired mode is set when the virtual machine is created. - Disallow MMIO access in x2APIC mode and MSR access in xAPIC mode. - Add support for x2APIC virtualization assist in Intel VT-x.

| | | | | | | | | | | | | | | | | | | | | | | | | Add virtualized XSAVE support to bhyve which permits guests to use XSAVE and XSAVE-enabled features like AVX. - Store a per-cpu guest xcr0 register and handle xsetbv VM exits by emulating the instruction. - Only expose XSAVE to guests if XSAVE is enabled in the host. Only expose a subset of XSAVE features currently supported by the guest and for which the proper emulation of xsetbv is known. Currently this includes X87, SSE, AVX, AVX-512, and Intel MPX. - Add support for injecting hardware exceptions into the guest and use this to trigger exceptions in the guest for invalid xsetbv operations instead of potentially faulting in the host. - Queue pending exceptions in the 'struct vcpu' instead of directly updating the processor-specific VMCS or VMCB. The pending exception will be delivered right before entering the guest. - Rename the unused ioctl VM_INJECT_EVENT to VM_INJECT_EXCEPTION and restrict it to only deliver x86 hardware exceptions. This new ioctl is now used to inject a protection fault when the guest accesses an unimplemented MSR. - Expose a subset of known-safe features from leaf 0 of the structured extended features to guests if they are supported on the host including RDFSBASE/RDGSBASE, BMI1/2, AVX2, AVX-512, HLE, ERMS, and RTM. Aside from AVX-512, these features are all new instructions available for use in ring 3 with no additional hypervisor changes needed.

* MFC 259737, 262646:jhb2014-05-181-1/+2
| | | | | | | | | | Fix a couple of issues with vcpu state: - Add a parameter to 'vcpu_set_state()' to enforce that the vcpu is in the IDLE state before the requested state transition. This guarantees that there is exactly one ioctl() operating on a vcpu at any point in time and prevents unintended state transitions. - Fix a race between VMRUN() and vcpu_notify_event() due to 'vcpu->hostcpu' being updated outside of the vcpu_lock().

| | | | | | | | | | | | | As of r257209, all architectures have defined VM_KMEM_SIZE_SCALE. In other words, every architecture is now auto-sizing the kmem arena. This revision changes kmeminit() so that the definition of VM_KMEM_SIZE_SCALE becomes mandatory and the definition of VM_KMEM_SIZE becomes optional. Replace or eliminate all existing definitions of VM_KMEM_SIZE. With auto-sizing enabled, VM_KMEM_SIZE effectively became an alternate spelling for VM_KMEM_SIZE_MIN on most architectures. Use VM_KMEM_SIZE_MIN for clarity.
