Add helper functions to populate VM exit information for rendezvous and astpending exits. Provide APIs to directly get 'lowmem' and 'highmem' size directly. Expose the amount of resident and wired memory from the guest's vmspace 2014-08-17T01:00:42Z Peter Grehan grehan@FreeBSD.org 2014-08-17T01:00:42Z urn:sha1:da18a2fc6a2db58c239fef4edf8a16d5fb9b1acd Add ioctl(VM_REINIT) to reinitialize the virtual machine state maintained by vmm.ko. This allows the virtual machine to be restarted without having to destroy it first. 2014-08-17T00:52:07Z Peter Grehan grehan@FreeBSD.org 2014-08-17T00:52:07Z urn:sha1:828bbc748a5827853bdeff99e99a9c040a119d1d Activate vcpus from bhyve(8) using the ioctl VM_ACTIVATE_CPU instead of doing it implicitly in vmm.ko. 2014-07-22T04:39:16Z John Baldwin jhb@FreeBSD.org 2014-07-22T04:39:16Z urn:sha1:d8b06a87d1f647ba02fde01c99746bfe17e2d70a 266708,266724,266934,266935,268521: Emulation of the "ins" and "outs" instructions. Various fixes for translating guest linear addresses to guest physical addresses. 2014-07-22T03:14:37Z John Baldwin jhb@FreeBSD.org 2014-07-22T03:14:37Z urn:sha1:8453fa9c95a28f8d7634d7c57f004d20ead1b870 Implement a PCI interrupt router to route PCI legacy INTx interrupts to the legacy 8259A PICs. 2014-07-21T19:08:02Z John Baldwin jhb@FreeBSD.org 2014-07-21T19:08:02Z urn:sha1:d0aa4007c69618c8a3bf88c9a0fc4ba5a62a73ac 265941,265951,266390,266550,266910: Various bhyve fixes: - Don't save host's return address in 'struct vmxctx'. - Permit non-32-bit accesses to local APIC registers. - Factor out common ioport handler code. - Use calloc() in favor of malloc + memset. - Change the vlapic timer frequency to be in the ballpark of contemporary hardware. - Allow the guest to read the TSC via MSR 0x10. - A VMCS is always inactive when it exits the vmx_run() loop. Remove redundant code and the misleading comment that suggest otherwise. - Ignore writes to microcode update MSR. This MSR is accessed by RHEL7 guest. Add KTR tracepoints to annotate wrmsr and rdmsr VM exits. - Provide an alias for the userboot console and name it 'comconsole'. - Use EV_ADD to create an mevent and EV_ENABLE to enable it. - abort(3) the process in response to a VMEXIT_ABORT. - Don't include the guest memory segments in the bhyve(8) process core dump. - Make the vmx asm code dtrace-fbt-friendly. - Allow vmx_getdesc() and vmx_setdesc() to be called for a vcpu that is in the VCPU_RUNNING state. - Enable VMX in the IA32_FEATURE_CONTROL MSR if it not enabled and the MSR isn't locked. 2014-07-21T02:39:17Z John Baldwin jhb@FreeBSD.org 2014-07-21T02:39:17Z urn:sha1:d47fc420ca941c9bcdf025f254ec1d20e54034f9 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'. 2014-07-19T22:06:46Z John Baldwin jhb@FreeBSD.org 2014-07-19T22:06:46Z urn:sha1:58f2a4bd1a158676f319b6f984c8433767ab82df 264648,264650,264651,266572,267558: Flesh out the AT PIC and 8254 PIT emulations and move them into the kernel. 2014-06-12T19:58:12Z John Baldwin jhb@FreeBSD.org 2014-06-12T19:58:12Z urn:sha1:de8cfcc7d7471639c6826dd98cb9887136d69c92 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.
