Current version is 1. New * | | versions are guaranteed to be backwards-compatible. * 8 +----------------+ * | flags | SIF_xxx flags. * 12 +----------------+ * | nr_modules | Number of modules passed to the kernel. * 16 +----------------+ * | modlist_paddr | Physical address of an array of modules * | | (layout of the structure below). * 24 +----------------+ * | cmdline_paddr | Physical address of the command line, * | | a zero-terminated ASCII string. * 32 +----------------+ * | rsdp_paddr | Physical address of the RSDP ACPI data structure. * 40 +----------------+ * | memmap_paddr | Physical address of the (optional) memory map. Only * | | present in version 1 and newer of the structure. * 48 +----------------+ * | memmap_entries | Number of entries in the memory map table. Zero * | | if there is no memory map being provided. Only * | | present in version 1 and newer of the structure. * 52 +----------------+ * | reserved | Version 1 and newer only. * 56 +----------------+ * * The layout of each entry in the module structure is the following: * * 0 +----------------+ * | paddr | Physical address of the module. * 8 +----------------+ * | size | Size of the module in bytes. * 16 +----------------+ * | cmdline_paddr | Physical address of the command line, * | | a zero-terminated ASCII string. * 24 +----------------+ * | reserved | * 32 +----------------+ * * The layout of each entry in the memory map table is as follows: * * 0 +----------------+ * | addr | Base address * 8 +----------------+ * | size | Size of mapping in bytes * 16 +----------------+ * | type | Type of mapping as defined between the hypervisor * | | and guest. See XEN_HVM_MEMMAP_TYPE_* values below. * 20 +----------------| * | reserved | * 24 +----------------+ * * The address and sizes are always a 64bit little endian unsigned integer. * * NB: Xen on x86 will always try to place all the data below the 4GiB * boundary. * * Version numbers of the hvm_start_info structure have evolved like this: * * Version 0: Initial implementation. * * Version 1: Added the memmap_paddr/memmap_entries fields (plus 4 bytes of * padding) to the end of the hvm_start_info struct. These new * fields can be used to pass a memory map to the guest. The * memory map is optional and so guests that understand version 1 * of the structure must check that memmap_entries is non-zero * before trying to read the memory map. */ #[repr(C)] #[derive(Debug, Copy, Clone, Default)] pub struct hvm_start_info { pub magic: u32, pub version: u32, pub flags: u32, pub nr_modules: u32, pub modlist_paddr: u64, pub cmdline_paddr: u64, pub rsdp_paddr: u64, pub memmap_paddr: u64, pub memmap_entries: u32, pub reserved: u32, } #[repr(C)] #[derive(Debug, Copy, Clone, Default)] pub struct hvm_modlist_entry { pub paddr: u64, pub size: u64, pub cmdline_paddr: u64, pub reserved: u64, } #[repr(C)] #[derive(Debug, Copy, Clone, Default)] pub struct hvm_memmap_table_entry { pub addr: u64, pub size: u64, pub type_: u32, pub reserved: u32, } #[cfg(test)] mod tests { use super::*;
