Functions§
- add_
e820_ 🔒entry - Add an e820 region to the e820 map.
- append_
multiboot_ 🔒info - arch_
memory_ regions - Returns a Vec of the valid memory addresses. These should be used to configure the GuestMemory structure for the platform. For x86_64 all addresses are valid from the start of the kernel except a carve out at the end of 32bit address space.
- bios_
start 🔒 - The x86 reset vector for i386+ and x86_64 puts the processor into an “unreal mode” where it can access the last 1 MB of the 32-bit address space in 16-bit mode, and starts the instruction pointer at the effective physical address 0xFFFF_FFF0.
- check_
host_ hybrid_ support - Check if host supports hybrid CPU feature. The check include: 1. Check if CPUID.1AH exists. CPUID.1AH is hybrid information enumeration leaf. 2. Check if CPUID.07H.00H:EDX[bit 15] sets. This bit means the processor is identified as a hybrid part. 3. Check if CPUID.1AH:EAX sets. The hybrid core type is set in EAX.
- configure_

multiboot_ 🔒info - create_
arch_ memory_ layout - find_
setup_ 🔒data - Find the first
setup_data_hdrwith the given type in guest memory and return its address. - generate_
e820_ 🔒memory_ map - Generate a memory map in INT 0x15 AX=0xE820 format.

data_ 🔒rng_ seed - Generate a SETUP_RNG_SEED SetupData with random seed data.

addr_ 🔒start - write_
setup_ 🔒data - Write setup_data entries in guest memory and link them together with the
nextfield.
