ArchMemoryLayout
CpuIdCall
The wrapper for CPUID call functions.
E820Entry 🔒
PciRootOSC 🔒
SetupData
A single entry to be inserted in the bootparam setup_data linked list.
X8664arch
setup_data_hdr 🔒

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_boot_params 🔒
configure_multiboot_info 🔒
create_arch_memory_layout
generate_e820_memory_map 🔒
Generate a memory map in INT 0x15 AX=0xE820 format.
get_cpu_manufacturer
identity_map_addr_start 🔒
setup_data_rng_seed 🔒
Generate a SETUP_RNG_SEED SetupData with random seed data.
tss_addr_end 🔒
tss_addr_start 🔒
write_setup_data 🔒
Write setup_data entries in guest memory and link them together with the next field.
