hvip

Hypervisor Virtual Interrupt Pending Register

The hvip register is an HSXLEN-bit read/write register that a hypervisor can write to indicate virtual interrupts intended for VS-mode. It contains interrupt-pending bits for virtual interrupts such as VS-level external interrupts, timer interrupts, and software interrupts.

Fields

`VSEIP`

Location: hvip[10]
Description: Pending interrupt bit for VS-level external interrupts. This bit is writable and is set to 1 to assert a VS-level external interrupt. TODO: assert the interrupt
Type

RW	Read-Write Field is writable by software. Any value that fits in the field is acceptable and shall be retained for subsequent reads.

Reset value: UNDEFINED_LEGAL

`VSTIP`

Location: hvip[6]
Description: Pending interrupt bit for VS-level timer interrupts. This bit is writable and is set to 1 to assert a VS-level timer interrupt. TODO: assert the interrupt
Type

RW	Read-Write Field is writable by software. Any value that fits in the field is acceptable and shall be retained for subsequent reads.

Reset value: UNDEFINED_LEGAL

`VSSIP`

Location: hvip[2]
Description: Pending interrupt bit for VS-level software interrupts. This bit is writable and is set to 1 to assert a VS-level software interrupt. TODO: assert the interrupt
Type

RW	Read-Write Field is writable by software. Any value that fits in the field is acceptable and shall be retained for subsequent reads.

Reset value: UNDEFINED_LEGAL
