Fix a recursive lock acquisition in vi_reset_dev(). 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. This allows the driver a chance to recover if for instance a timeout occurred due to activity on the host.
