Simplify the assignment of memory to virtual machines by requiring a single command line option "-m <memsize in MB>" to specify the memory size. Prior to this change the user needed to explicitly specify the amount of memory allocated below 4G (-m <lowmem>) and the amount above 4G (-M <highmem>). The "-M" option is no longer supported by 'bhyveload' and 'bhyve'. The start of the PCI hole is fixed at 3GB and cannot be directly changed using command line options. However it is still possible to change this in special circumstances via the 'vm_set_lowmem_limit()' API provided by libvmmapi.

Merge projects/bhyve_npt_pmap into head. Make the amd64/pmap code aware of nested page table mappings used by bhyve guests. This allows bhyve to associate each guest with its own vmspace and deal with nested page faults in the context of that vmspace. This also enables features like accessed/dirty bit tracking, swapping to disk and transparent superpage promotions of guest memory. Guest vmspace: Each bhyve guest has a unique vmspace to represent the physical memory allocated to the guest. Each memory segment allocated by the guest is mapped into the guest's address space via the 'vmspace->vm_map' and is backed by an object of type OBJT_DEFAULT. pmap types: The amd64/pmap now understands two types of pmaps: PT_X86 and PT_EPT. The PT_X86 pmap type is used by the vmspace associated with the host kernel as well as user processes executing on the host. The PT_EPT pmap is used by the vmspace associated with a bhyve guest. Page Table Entries: The EPT page table entries as mostly similar in functionality to regular page table entries although there are some differences in terms of what bits are used to express that functionality. For e.g. the dirty bit is represented by bit 9 in the nested PTE as opposed to bit 6 in the regular x86 PTE. Therefore the bitmask representing the dirty bit is now computed at runtime based on the type of the pmap. Thus PG_M that was previously a macro now becomes a local variable that is initialized at runtime using 'pmap_modified_bit(pmap)'. An additional wrinkle associated with EPT mappings is that older Intel processors don't have hardware support for tracking accessed/dirty bits in the PTE. This means that the amd64/pmap code needs to emulate these bits to provide proper accounting to the VM subsystem. This is achieved by using the following mapping for EPT entries that need emulation of A/D bits: Bit Position Interpreted By PG_V 52 software (accessed bit emulation handler) PG_RW 53 software (dirty bit emulation handler) PG_A 0 hardware (aka EPT_PG_RD) PG_M 1 hardware (aka EPT_PG_WR) The idea to use the mapping listed above for A/D bit emulation came from Alan Cox (alc@). The final difference with respect to x86 PTEs is that some EPT implementations do not support superpage mappings. This is recorded in the 'pm_flags' field of the pmap. TLB invalidation: The amd64/pmap code has a number of ways to do invalidation of mappings that may be cached in the TLB: single page, multiple pages in a range or the entire TLB. All of these funnel into a single EPT invalidation routine called 'pmap_invalidate_ept()'. This routine bumps up the EPT generation number and sends an IPI to the host cpus that are executing the guest's vcpus. On a subsequent entry into the guest it will detect that the EPT has changed and invalidate the mappings from the TLB. Guest memory access: Since the guest memory is no longer wired we need to hold the host physical page that backs the guest physical page before we can access it. The helper functions 'vm_gpa_hold()/vm_gpa_release()' are available for this purpose. PCI passthru: Guest's with PCI passthru devices will wire the entire guest physical address space. The MMIO BAR associated with the passthru device is backed by a vm_object of type OBJT_SG. An IOMMU domain is created only for guest's that have one or more PCI passthru devices attached to them. Limitations: There isn't a way to map a guest physical page without execute permissions. This is because the amd64/pmap code interprets the guest physical mappings as user mappings since they are numerically below VM_MAXUSER_ADDRESS. Since PG_U shares the same bit position as EPT_PG_EXECUTE all guest mappings become automatically executable. Thanks to Alan Cox and Konstantin Belousov for their rigorous code reviews as well as their support and encouragement. Thanks for John Baldwin for reviewing the use of OBJT_SG as the backing object for pci passthru mmio regions. Special thanks to Peter Holm for testing the patch on short notice.

Also modify the 'HLT' processing to ignore pending interrupts in the IRR if interrupts have been disabled by the guest. The interrupt cannot be injected into the guest in any case so resuming it is futile. - Use callout(9) to drive the vlapic timer instead of clocking it on each VM exit. - When the guest is bringing up the APs in the x2APIC mode a write to the ICR register will now trigger a return to userspace with an exitcode of VM_EXITCODE_SPINUP_AP. - Change the vlapic timer lock to be a spinlock because the vlapic can be accessed from within a critical section (vm run loop) when guest is using x2apic mode. - Fix the vlapic version register. - Add a command to bhyvectl to inject an NMI on a specific vcpu. - Add an API to deliver message signalled interrupts to vcpus. This allows callers to treat the MSI 'addr' and 'data' fields as opaque and also lets bhyve implement multiple destination modes: physical, flat and clustered. - Rename the ambiguously named 'vm_setup_msi()' and 'vm_setup_msix()' to 'vm_setup_pptdev_msi()' and 'vm_setup_pptdev_msix()' respectively. - Consolidate the virtual apic initialization in a single function: vlapic_reset() - Add a generic routine to trigger an LVT interrupt that supports both fixed and NMI delivery modes. - Add an ioctl and bhyvectl command to trigger local interrupts inside a guest. In particular, a global NMI similar to that raised by SERR# or PERR# can be simulated by asserting LINT1 on all vCPUs. - Extend the LVT table in the vCPU local APIC to support CMCI. - Flesh out the local APIC error reporting a bit to cache errors and report them via ESR when ESR is written to. Add support for asserting the error LVT when an error occurs. Raise illegal vector errors when attempting to signal an invalid vector for an interrupt or when sending an IPI. - Export table entries in the MADT and MP Table advertising the stock x86 config of LINT0 set to ExtInt and LINT1 wired to NMI.

Merge projects/bhyve_npt_pmap into head. Make the amd64/pmap code aware of nested page table mappings used by bhyve guests. This allows bhyve to associate each guest with its own vmspace and deal with nested page faults in the context of that vmspace. This also enables features like accessed/dirty bit tracking, swapping to disk and transparent superpage promotions of guest memory. Guest vmspace: Each bhyve guest has a unique vmspace to represent the physical memory allocated to the guest. Each memory segment allocated by the guest is mapped into the guest's address space via the 'vmspace->vm_map' and is backed by an object of type OBJT_DEFAULT. pmap types: The amd64/pmap now understands two types of pmaps: PT_X86 and PT_EPT. The PT_X86 pmap type is used by the vmspace associated with the host kernel as well as user processes executing on the host. The PT_EPT pmap is used by the vmspace associated with a bhyve guest. Page Table Entries: The EPT page table entries as mostly similar in functionality to regular page table entries although there are some differences in terms of what bits are used to express that functionality. For e.g. the dirty bit is represented by bit 9 in the nested PTE as opposed to bit 6 in the regular x86 PTE. Therefore the bitmask representing the dirty bit is now computed at runtime based on the type of the pmap. Thus PG_M that was previously a macro now becomes a local variable that is initialized at runtime using 'pmap_modified_bit(pmap)'. An additional wrinkle associated with EPT mappings is that older Intel processors don't have hardware support for tracking accessed/dirty bits in the PTE. This means that the amd64/pmap code needs to emulate these bits to provide proper accounting to the VM subsystem. This is achieved by using the following mapping for EPT entries that need emulation of A/D bits: Bit Position Interpreted By PG_V 52 software (accessed bit emulation handler) PG_RW 53 software (dirty bit emulation handler) PG_A 0 hardware (aka EPT_PG_RD) PG_M 1 hardware (aka EPT_PG_WR) The idea to use the mapping listed above for A/D bit emulation came from Alan Cox (alc@). The final difference with respect to x86 PTEs is that some EPT implementations do not support superpage mappings. This is recorded in the 'pm_flags' field of the pmap. TLB invalidation: The amd64/pmap code has a number of ways to do invalidation of mappings that may be cached in the TLB: single page, multiple pages in a range or the entire TLB. All of these funnel into a single EPT invalidation routine called 'pmap_invalidate_ept()'. This routine bumps up the EPT generation number and sends an IPI to the host cpus that are executing the guest's vcpus. On a subsequent entry into the guest it will detect that the EPT has changed and invalidate the mappings from the TLB. Guest memory access: Since the guest memory is no longer wired we need to hold the host physical page that backs the guest physical page before we can access it. The helper functions 'vm_gpa_hold()/vm_gpa_release()' are available for this purpose. PCI passthru: Guest's with PCI passthru devices will wire the entire guest physical address space. The MMIO BAR associated with the passthru device is backed by a vm_object of type OBJT_SG. An IOMMU domain is created only for guest's that have one or more PCI passthru devices attached to them. Limitations: There isn't a way to map a guest physical page without execute permissions. This is because the amd64/pmap code interprets the guest physical mappings as user mappings since they are numerically below VM_MAXUSER_ADDRESS. Since PG_U shares the same bit position as EPT_PG_EXECUTE all guest mappings become automatically executable. Thanks to Alan Cox and Konstantin Belousov for their rigorous code reviews as well as their support and encouragement. Thanks for John Baldwin for reviewing the use of OBJT_SG as the backing object for pci passthru mmio regions. Special thanks to Peter Holm for testing the patch on short notice.

Also modify the 'HLT' processing to ignore pending interrupts in the IRR if interrupts have been disabled by the guest. The interrupt cannot be injected into the guest in any case so resuming it is futile. - Use callout(9) to drive the vlapic timer instead of clocking it on each VM exit. - When the guest is bringing up the APs in the x2APIC mode a write to the ICR register will now trigger a return to userspace with an exitcode of VM_EXITCODE_SPINUP_AP. - Change the vlapic timer lock to be a spinlock because the vlapic can be accessed from within a critical section (vm run loop) when guest is using x2apic mode. - Fix the vlapic version register. - Add a command to bhyvectl to inject an NMI on a specific vcpu. - Add an API to deliver message signalled interrupts to vcpus. This allows callers to treat the MSI 'addr' and 'data' fields as opaque and also lets bhyve implement multiple destination modes: physical, flat and clustered. - Rename the ambiguously named 'vm_setup_msi()' and 'vm_setup_msix()' to 'vm_setup_pptdev_msi()' and 'vm_setup_pptdev_msix()' respectively. - Consolidate the virtual apic initialization in a single function: vlapic_reset() - Add a generic routine to trigger an LVT interrupt that supports both fixed and NMI delivery modes. - Add an ioctl and bhyvectl command to trigger local interrupts inside a guest. In particular, a global NMI similar to that raised by SERR# or PERR# can be simulated by asserting LINT1 on all vCPUs. - Extend the LVT table in the vCPU local APIC to support CMCI. - Flesh out the local APIC error reporting a bit to cache errors and report them via ESR when ESR is written to. Add support for asserting the error LVT when an error occurs. Raise illegal vector errors when attempting to signal an invalid vector for an interrupt or when sending an IPI. - Export table entries in the MADT and MP Table advertising the stock x86 config of LINT0 set to ExtInt and LINT1 wired to NMI.

Simplify the assignment of memory to virtual machines by requiring a single command line option "-m <memsize in MB>" to specify the memory size. Prior to this change the user needed to explicitly specify the amount of memory allocated below 4G (-m <lowmem>) and the amount above 4G (-M <highmem>). The "-M" option is no longer supported by 'bhyveload' and 'bhyve'. The start of the PCI hole is fixed at 3GB and cannot be directly changed using command line options. However it is still possible to change this in special circumstances via the 'vm_set_lowmem_limit()' API provided by libvmmapi.

MFC r282209: Emulate the 'bit test' instruction. MFC r282259: Re-implement RTC current time calculation to eliminate the possibility of losing time. MFC r282281: Advertise the MTRR feature via CPUID and emulate the minimal set of MTRR MSRs. MFC r282284: When an instruction cannot be decoded just return to userspace so bhyve(8) can dump the instruction bytes. MFC r282287: Don't require <sys/cpuset.h> to be always included before <machine/vmm.h>. MFC r282296: Emulate MSR_SYSCFG which is accessed by Linux on AMD cpus when MTRRs are enabled. MFC r282301: Relax limits when transitioning a vector from the IRR to the ISR and also when extinguishing it from the ISR in response to an EOI. MFC r282335: Advertise an additional memory BAR in the "dummy" device emulation. MFC r282336: Emulate machine check related MSRs to allow guest OSes like Windows to boot. MFC r282351: Don't advertise the Intel SMX capability to the guest. MFC r282407: Emulate the 'CMP r/m8, imm8' instruction. MFC r282519: Add macros for AMD-specific bits in MSR_EFER: LMSLE, FFXSR and TCE. MFC r282520: Emulate guest writes to EFER_MSR properly. MFC r282558: Deprecate the 3-way return values from vm_gla2gpa() and vm_copy_setup(). MFC r282571: Check 'td_owepreempt' and yield the vcpu thread if it is set. MFC r282595: Allow byte reads of AHCI registers. MFC r282784: Handling indirect descriptors is a capability of the host and not one that needs to be negotiated. 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. MFC r282922: Bump the size of the blockif scatter-gather list to 67. MFC r283075: Fix off-by-one in array index bounds check. bhyveload would allow you to create 33 entries on an array that only has 32 slots MFC r283168: Temporarily revert r282922 which bumped the max descriptors. MFC r283255: Emulate the "CMP r/m, reg" instruction (opcode 39H). MFC r283256: Add an option "--get-vmcs-exit-inst-length" to display the instruction length of the instruction that caused the VM-exit. MFC r283264: Change the header type of the emulated host-bridge from type 1 to type 0. MFC r283293: Don't rely on the 'VM-exit instruction length' field in the VMCS to always have an accurate length on an EPT violation. MFC r283299: Remove bogus verification of instruction length after instruction decode. MFC r283308: Exceptions don't deliver an error code in real mode. MFC r283657: Fix non-deterministic delays when accessing a vcpu that was in "running" or "sleeping" state. MFC r283973: Use tunable 'hw.vmm.svm.features' to disable specific SVM features even though they might be available in hardware. Use tunable 'hw.vmm.svm.num_asids' to limit the number of ASIDs used by the hypervisor. MFC r284046: Fix regression in 'verify_gla()' with the RIP-relative addressing mode. MFC r284174: Support guest writes to the TSC by enabling the "use TSC offsetting" execution control.

Simplify the assignment of memory to virtual machines by requiring a single command line option "-m <memsize in MB>" to specify the memory size. Prior to this change the user needed to explicitly specify the amount of memory allocated below 4G (-m <lowmem>) and the amount above 4G (-M <highmem>). The "-M" option is no longer supported by 'bhyveload' and 'bhyve'. The start of the PCI hole is fixed at 3GB and cannot be directly changed using command line options. However it is still possible to change this in special circumstances via the 'vm_set_lowmem_limit()' API provided by libvmmapi.

UNASSIGN_PPTDEV,
Merge projects/bhyve_npt_pmap into head. Make the amd64/pmap code aware of nested page table mappings used by bhyve guests. This allows bhyve to associate each guest with its own vmspace and deal with nested page faults in the context of that vmspace. This also enables features like accessed/dirty bit tracking, swapping to disk and transparent superpage promotions of guest memory. Guest vmspace: Each bhyve guest has a unique vmspace to represent the physical memory allocated to the guest. Each memory segment allocated by the guest is mapped into the guest's address space via the 'vmspace->vm_map' and is backed by an object of type OBJT_DEFAULT. pmap types: The amd64/pmap now understands two types of pmaps: PT_X86 and PT_EPT. The PT_X86 pmap type is used by the vmspace associated with the host kernel as well as user processes executing on the host. The PT_EPT pmap is used by the vmspace associated with a bhyve guest. Page Table Entries: The EPT page table entries as mostly similar in functionality to regular page table entries although there are some differences in terms of what bits are used to express that functionality. For e.g. the dirty bit is represented by bit 9 in the nested PTE as opposed to bit 6 in the regular x86 PTE. Therefore the bitmask representing the dirty bit is now computed at runtime based on the type of the pmap. Thus PG_M that was previously a macro now becomes a local variable that is initialized at runtime using 'pmap_modified_bit(pmap)'. An additional wrinkle associated with EPT mappings is that older Intel processors don't have hardware support for tracking accessed/dirty bits in the PTE. This means that the amd64/pmap code needs to emulate these bits to provide proper accounting to the VM subsystem. This is achieved by using the following mapping for EPT entries that need emulation of A/D bits: Bit Position Interpreted By PG_V 52 software (accessed bit emulation handler) PG_RW 53 software (dirty bit emulation handler) PG_A 0 hardware (aka EPT_PG_RD) PG_M 1 hardware (aka EPT_PG_WR) The idea to use the mapping listed above for A/D bit emulation came from Alan Cox (alc@). The final difference with respect to x86 PTEs is that some EPT implementations do not support superpage mappings. This is recorded in the 'pm_flags' field of the pmap. TLB invalidation: The amd64/pmap code has a number of ways to do invalidation of mappings that may be cached in the TLB: single page, multiple pages in a range or the entire TLB. All of these funnel into a single EPT invalidation routine called 'pmap_invalidate_ept()'. This routine bumps up the EPT generation number and sends an IPI to the host cpus that are executing the guest's vcpus. On a subsequent entry into the guest it will detect that the EPT has changed and invalidate the mappings from the TLB. Guest memory access: Since the guest memory is no longer wired we need to hold the host physical page that backs the guest physical page before we can access it. The helper functions 'vm_gpa_hold()/vm_gpa_release()' are available for this purpose. PCI passthru: Guest's with PCI passthru devices will wire the entire guest physical address space. The MMIO BAR associated with the passthru device is backed by a vm_object of type OBJT_SG. An IOMMU domain is created only for guest's that have one or more PCI passthru devices attached to them. Limitations: There isn't a way to map a guest physical page without execute permissions. This is because the amd64/pmap code interprets the guest physical mappings as user mappings since they are numerically below VM_MAXUSER_ADDRESS. Since PG_U shares the same bit position as EPT_PG_EXECUTE all guest mappings become automatically executable. Thanks to Alan Cox and Konstantin Belousov for their rigorous code reviews as well as their support and encouragement. Thanks for John Baldwin for reviewing the use of OBJT_SG as the backing object for pci passthru mmio regions. Special thanks to Peter Holm for testing the patch on short notice.

Also modify the 'HLT' processing to ignore pending interrupts in the IRR if interrupts have been disabled by the guest. The interrupt cannot be injected into the guest in any case so resuming it is futile. - Use callout(9) to drive the vlapic timer instead of clocking it on each VM exit. - When the guest is bringing up the APs in the x2APIC mode a write to the ICR register will now trigger a return to userspace with an exitcode of VM_EXITCODE_SPINUP_AP. - Change the vlapic timer lock to be a spinlock because the vlapic can be accessed from within a critical section (vm run loop) when guest is using x2apic mode. - Fix the vlapic version register. - Add a command to bhyvectl to inject an NMI on a specific vcpu. - Add an API to deliver message signalled interrupts to vcpus. This allows callers to treat the MSI 'addr' and 'data' fields as opaque and also lets bhyve implement multiple destination modes: physical, flat and clustered. - Rename the ambiguously named 'vm_setup_msi()' and 'vm_setup_msix()' to 'vm_setup_pptdev_msi()' and 'vm_setup_pptdev_msix()' respectively. - Consolidate the virtual apic initialization in a single function: vlapic_reset() - Add a generic routine to trigger an LVT interrupt that supports both fixed and NMI delivery modes. - Add an ioctl and bhyvectl command to trigger local interrupts inside a guest. In particular, a global NMI similar to that raised by SERR# or PERR# can be simulated by asserting LINT1 on all vCPUs. - Extend the LVT table in the vCPU local APIC to support CMCI. - Flesh out the local APIC error reporting a bit to cache errors and report them via ESR when ESR is written to. Add support for asserting the error LVT when an error occurs. Raise illegal vector errors when attempting to signal an invalid vector for an interrupt or when sending an IPI. - Export table entries in the MADT and MP Table advertising the stock x86 config of LINT0 set to ExtInt and LINT1 wired to NMI.

MFC r282209: Emulate the 'bit test' instruction. MFC r282259: Re-implement RTC current time calculation to eliminate the possibility of losing time. MFC r282281: Advertise the MTRR feature via CPUID and emulate the minimal set of MTRR MSRs. MFC r282284: When an instruction cannot be decoded just return to userspace so bhyve(8) can dump the instruction bytes. MFC r282287: Don't require <sys/cpuset.h> to be always included before <machine/vmm.h>. MFC r282296: Emulate MSR_SYSCFG which is accessed by Linux on AMD cpus when MTRRs are enabled. MFC r282301: Relax limits when transitioning a vector from the IRR to the ISR and also when extinguishing it from the ISR in response to an EOI. MFC r282335: Advertise an additional memory BAR in the "dummy" device emulation. MFC r282336: Emulate machine check related MSRs to allow guest OSes like Windows to boot. MFC r282351: Don't advertise the Intel SMX capability to the guest. MFC r282407: Emulate the 'CMP r/m8, imm8' instruction. MFC r282519: Add macros for AMD-specific bits in MSR_EFER: LMSLE, FFXSR and TCE. MFC r282520: Emulate guest writes to EFER_MSR properly. MFC r282558: Deprecate the 3-way return values from vm_gla2gpa() and vm_copy_setup(). MFC r282571: Check 'td_owepreempt' and yield the vcpu thread if it is set. MFC r282595: Allow byte reads of AHCI registers. MFC r282784: Handling indirect descriptors is a capability of the host and not one that needs to be negotiated. 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. MFC r282922: Bump the size of the blockif scatter-gather list to 67. MFC r283075: Fix off-by-one in array index bounds check. bhyveload would allow you to create 33 entries on an array that only has 32 slots MFC r283168: Temporarily revert r282922 which bumped the max descriptors. MFC r283255: Emulate the "CMP r/m, reg" instruction (opcode 39H). MFC r283256: Add an option "--get-vmcs-exit-inst-length" to display the instruction length of the instruction that caused the VM-exit. MFC r283264: Change the header type of the emulated host-bridge from type 1 to type 0. MFC r283293: Don't rely on the 'VM-exit instruction length' field in the VMCS to always have an accurate length on an EPT violation. MFC r283299: Remove bogus verification of instruction length after instruction decode. MFC r283308: Exceptions don't deliver an error code in real mode. MFC r283657: Fix non-deterministic delays when accessing a vcpu that was in "running" or "sleeping" state. MFC r283973: Use tunable 'hw.vmm.svm.features' to disable specific SVM features even though they might be available in hardware. Use tunable 'hw.vmm.svm.num_asids' to limit the number of ASIDs used by the hypervisor. MFC r284046: Fix regression in 'verify_gla()' with the RIP-relative addressing mode. MFC r284174: Support guest writes to the TSC by enabling the "use TSC offsetting" execution control.

MFC r282209: Emulate the 'bit test' instruction. MFC r282259: Re-implement RTC current time calculation to eliminate the possibility of losing time. MFC r282281: Advertise the MTRR feature via CPUID and emulate the minimal set of MTRR MSRs. MFC r282284: When an instruction cannot be decoded just return to userspace so bhyve(8) can dump the instruction bytes. MFC r282287: Don't require <sys/cpuset.h> to be always included before <machine/vmm.h>. MFC r282296: Emulate MSR_SYSCFG which is accessed by Linux on AMD cpus when MTRRs are enabled. MFC r282301: Relax limits when transitioning a vector from the IRR to the ISR and also when extinguishing it from the ISR in response to an EOI. MFC r282335: Advertise an additional memory BAR in the "dummy" device emulation. MFC r282336: Emulate machine check related MSRs to allow guest OSes like Windows to boot. MFC r282351: Don't advertise the Intel SMX capability to the guest. MFC r282407: Emulate the 'CMP r/m8, imm8' instruction. MFC r282519: Add macros for AMD-specific bits in MSR_EFER: LMSLE, FFXSR and TCE. MFC r282520: Emulate guest writes to EFER_MSR properly. MFC r282558: Deprecate the 3-way return values from vm_gla2gpa() and vm_copy_setup(). MFC r282571: Check 'td_owepreempt' and yield the vcpu thread if it is set. MFC r282595: Allow byte reads of AHCI registers. MFC r282784: Handling indirect descriptors is a capability of the host and not one that needs to be negotiated. 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. MFC r282922: Bump the size of the blockif scatter-gather list to 67. MFC r283075: Fix off-by-one in array index bounds check. bhyveload would allow you to create 33 entries on an array that only has 32 slots MFC r283168: Temporarily revert r282922 which bumped the max descriptors. MFC r283255: Emulate the "CMP r/m, reg" instruction (opcode 39H). MFC r283256: Add an option "--get-vmcs-exit-inst-length" to display the instruction length of the instruction that caused the VM-exit. MFC r283264: Change the header type of the emulated host-bridge from type 1 to type 0. MFC r283293: Don't rely on the 'VM-exit instruction length' field in the VMCS to always have an accurate length on an EPT violation. MFC r283299: Remove bogus verification of instruction length after instruction decode. MFC r283308: Exceptions don't deliver an error code in real mode. MFC r283657: Fix non-deterministic delays when accessing a vcpu that was in "running" or "sleeping" state. MFC r283973: Use tunable 'hw.vmm.svm.features' to disable specific SVM features even though they might be available in hardware. Use tunable 'hw.vmm.svm.num_asids' to limit the number of ASIDs used by the hypervisor. MFC r284046: Fix regression in 'verify_gla()' with the RIP-relative addressing mode. MFC r284174: Support guest writes to the TSC by enabling the "use TSC offsetting" execution control.

MFC r276428: Replace bhyve's minimal RTC emulation with a fully featured one in vmm.ko. MFC r276432: Initialize all fields of 'struct vm_exception exception' before passing it to vm_inject_exception(). MFC r276763: Clear blocking due to STI or MOV SS in the hypervisor when an instruction is emulated or when the vcpu incurs an exception. MFC r277149: Clean up usage of 'struct vm_exception' to only to communicate information from userspace to vmm.ko when injecting an exception. MFC r277168: Fix typo (missing comma). MFC r277309: Make the error message explicit instead of just printing the usage if the virtual machine name is not specified. MFC r277310: Simplify instruction restart logic in bhyve. MFC r277359: Fix a bug in libvmmapi 'vm_copy_setup()' where it would return success even if the 'gpa' was in the guest MMIO region. MFC r277360: MOVS instruction emulation. MFC r277626: Add macro to identify AVIC capability (advanced virtual interrupt controller) in AMD processors. MFC r279220: Don't close a block context if it couldn't be opened avoiding a null deref. MFC r279225: Add "-u" option to bhyve(8) to indicate that the RTC should maintain UTC time. MFC r279227: Emulate MSR 0xC0011024 when running on AMD processors. MFC r279228: Always emulate MSR_PAT on Intel processors and don't rely on PAT save/restore capability of VT-x. This lets bhyve run nested in older VMware versions that don't support the PAT save/restore capability. MFC r279540: Fix warnings/errors when building vmm.ko with gcc.

Merge projects/bhyve_npt_pmap into head. Make the amd64/pmap code aware of nested page table mappings used by bhyve guests. This allows bhyve to associate each guest with its own vmspace and deal with nested page faults in the context of that vmspace. This also enables features like accessed/dirty bit tracking, swapping to disk and transparent superpage promotions of guest memory. Guest vmspace: Each bhyve guest has a unique vmspace to represent the physical memory allocated to the guest. Each memory segment allocated by the guest is mapped into the guest's address space via the 'vmspace->vm_map' and is backed by an object of type OBJT_DEFAULT. pmap types: The amd64/pmap now understands two types of pmaps: PT_X86 and PT_EPT. The PT_X86 pmap type is used by the vmspace associated with the host kernel as well as user processes executing on the host. The PT_EPT pmap is used by the vmspace associated with a bhyve guest. Page Table Entries: The EPT page table entries as mostly similar in functionality to regular page table entries although there are some differences in terms of what bits are used to express that functionality. For e.g. the dirty bit is represented by bit 9 in the nested PTE as opposed to bit 6 in the regular x86 PTE. Therefore the bitmask representing the dirty bit is now computed at runtime based on the type of the pmap. Thus PG_M that was previously a macro now becomes a local variable that is initialized at runtime using 'pmap_modified_bit(pmap)'. An additional wrinkle associated with EPT mappings is that older Intel processors don't have hardware support for tracking accessed/dirty bits in the PTE. This means that the amd64/pmap code needs to emulate these bits to provide proper accounting to the VM subsystem. This is achieved by using the following mapping for EPT entries that need emulation of A/D bits: Bit Position Interpreted By PG_V 52 software (accessed bit emulation handler) PG_RW 53 software (dirty bit emulation handler) PG_A 0 hardware (aka EPT_PG_RD) PG_M 1 hardware (aka EPT_PG_WR) The idea to use the mapping listed above for A/D bit emulation came from Alan Cox (alc@). The final difference with respect to x86 PTEs is that some EPT implementations do not support superpage mappings. This is recorded in the 'pm_flags' field of the pmap. TLB invalidation: The amd64/pmap code has a number of ways to do invalidation of mappings that may be cached in the TLB: single page, multiple pages in a range or the entire TLB. All of these funnel into a single EPT invalidation routine called 'pmap_invalidate_ept()'. This routine bumps up the EPT generation number and sends an IPI to the host cpus that are executing the guest's vcpus. On a subsequent entry into the guest it will detect that the EPT has changed and invalidate the mappings from the TLB. Guest memory access: Since the guest memory is no longer wired we need to hold the host physical page that backs the guest physical page before we can access it. The helper functions 'vm_gpa_hold()/vm_gpa_release()' are available for this purpose. PCI passthru: Guest's with PCI passthru devices will wire the entire guest physical address space. The MMIO BAR associated with the passthru device is backed by a vm_object of type OBJT_SG. An IOMMU domain is created only for guest's that have one or more PCI passthru devices attached to them. Limitations: There isn't a way to map a guest physical page without execute permissions. This is because the amd64/pmap code interprets the guest physical mappings as user mappings since they are numerically below VM_MAXUSER_ADDRESS. Since PG_U shares the same bit position as EPT_PG_EXECUTE all guest mappings become automatically executable. Thanks to Alan Cox and Konstantin Belousov for their rigorous code reviews as well as their support and encouragement. Thanks for John Baldwin for reviewing the use of OBJT_SG as the backing object for pci passthru mmio regions. Special thanks to Peter Holm for testing the patch on short notice.

MFC r256645. Add a new capability, VM_CAP_ENABLE_INVPCID, that can be enabled to expose 'invpcid' instruction to the guest. Currently bhyve will try to enable this capability unconditionally if it is available. Consolidate code in bhyve to set the capabilities so it is no longer duplicated in BSP and AP bringup. Add a sysctl 'vm.pmap.invpcid_works' to display whether the 'invpcid' instruction is available. Approved by: re (hrs)
