Module hypercall

Hypercall infrastructure.

Structs

HvCall

Provides mechanisms to invoke hypercalls within the boot shim. Internally uses static buffers for the hypercall page, the input page, and the output page, so this should not be used in any multi-threaded capacity (which the boot shim currently is not).

HvcallPage 🔒

Page-aligned, page-sized buffer for use with hypercalls

Statics

HVCALL 🔒

HVCALL_INPUT 🔒

Static, reusable page for hypercall input

HVCALL_OUTPUT 🔒

Static, reusable page for hypercall output

Functions

hvcall

Returns an HvCall instance.

Type Aliases
