Checking CPU capabilities (VMX support, etc.) for the BSP and APs
Bitmap page-frame allocator
Power-of-two freelist heap allocator
4-level paging
- Replacing bootloader-provided page tables with custom tables
GDT/IDT/TSS setup
UART driver for serial output
- Including coloring via ANSI escape sequences
Basic spinlock implementation
Basic per-cpu variables support
xAPIC/x2APIC support
- Including support for computing the APIC timer frequency
Basic HPET driver to support HPET-based busy sleeping
Timer infrastructure
- Multiple approaches for determining the TSC frequency
- Support for one-shot and periodic timers

Virtualization specific:

Entering & leaving VMX operation on each logical processor
Verifying VMX capabilities (e.g. EPT support)
Creating and validating VMX policies that specify the features a VM requires
Initializing VMCS execution control fields and the VMCS host state area
Initializing register & non-register VMCS guest state according to the type of guest
VM-entry and VM-exit handlers
Creation of EPT mappings to virtualize guest physical memory
- Including support to copy data into a VM's address space
Parsing and validating bzImage kernel images
Support for directly booting and running bzImage kernels via the 32-bit Linux x86 boot protocol
