Hypervisor Interrupt Enable Register

The hie register is a read/write register in HS-mode that enables interrupts. It corresponds to the enable bits for VS-level and hypervisor-specific interrupts, and supplements the HS-level sie register.

Fields

`SGEIE`

Location: hie[12]
Description: Hypervisor guest external interrupt enable bit. When set, allows external interrupts to be delivered to VS-mode based on the hgeie setting.
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

Software write

This field has special behavior when written by software (e.g., through csrrw).

When software tries to write csr_value, the field will be written with the return value of the function below.

return csr_value.SGEIE;

`VSEIE`

Location: hie[10]
Description: VS-level external interrupt enable bit. When set, allows external interrupts directed to VS-level to be processed based on the configuration in hvip and other platform-specific sources.
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

Software write

This field has special behavior when written by software (e.g., through csrrw).

When software tries to write csr_value, the field will be written with the return value of the function below.

return csr_value.VSEIE;

`VSTIE`

Location: hie[6]
Description: VS-level timer interrupt enable bit. When set, allows VS-level timer interrupts to be processed based on the hvip configuration and any platform-specific timer interrupts.
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

Software write

This field has special behavior when written by software (e.g., through csrrw).

When software tries to write csr_value, the field will be written with the return value of the function below.

return csr_value.VSTIE;

`VSSIE`

Location: hie[2]
Description: VS-level software interrupt enable bit. When set, allows software interrupts directed to VS-level to be processed, based on the configuration in hvip.
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.
