Crate openhcl_boot

Source
Expand description

The openhcl boot loader, which loads before the kernel to set up the kernel’s boot parameters.

Modules§

  • arch 🔒
    Imports and re-exports architecture-specific implementations.
  • boot_logger 🔒
    Logging support for the bootshim.
  • cmdline 🔒
    Command line arguments and parsing for openhcl_boot.
  • dt 🔒
    Module used to write the device tree used by the OpenHCL kernel and usermode.
  • host_params 🔒
    Module used to parse the host parameters used to setup Underhill. These are provided via a device tree IGVM parameter.
  • hypercall 🔒
    Hypercall infrastructure.
  • rt 🔒
    Architecture-independent runtime support.
  • sidecar 🔒
  • single_threaded 🔒
    Support for working with global variables in a single-threaded environment. In such an environment, it is safe to access globals even if they don’t implement Sync, since there is only one thread that can access them. But code still needs to be careful to avoid creating multiple mutable references to the same global. These types provide abstractions for doing this safely.
  • x86_boot 🔒

Constants§

Functions§

  • build_cc_blob_sev_info 🔒
    Build the cc_blob containing the location of different parameters associated with SEV.
  • build_kernel_command_line 🔒
    Read and setup the underhill kernel command line into the specified buffer.
  • get_ref_time 🔒
  • main 🔒
  • reserved_memory_regions 🔒
    Construct a slice representing the reserved memory ranges to be reported to VTL2.
  • shim_main 🔒
  • shim_parameters 🔒
    Raw shim parameters are provided via a relative offset from the base of where the shim is loaded. Return a ShimParams structure based on the raw offset based RawShimParams.
  • validate_vp_hw_ids 🔒
    Ensure that mshv VP indexes for the CPUs listed in the partition info correspond to the N in the cpu@N devicetree node name. OpenVMM assumes that this will be the case.
  • zeroed 🔒
