Name:e820__print_table

Proto:void __init e820__print_table(char *who)

Type:void

Parameter:

TypeParameterName
char *who
207  When i < nr_entries cycle
208  pr_info("%s: [mem %#018Lx-%#018Lx] ", who, addr, addr + size - 1)
213  e820_print_type(type)
214  Like KERN_CONT, pr_cont() should only be used when continuing* a line with no newline ('\n') enclosed. Otherwise it defaults* back to KERN_DEFAULT.("\n")
Caller
NameDescribe
e820__update_table_print
e820__memory_setup_extendedBecause of the small fixed size of struct boot_params, only the first* 128 E820 memory entries are passed to the kernel via boot_params.e820_table,* the remaining (if any) entries are passed via the SETUP_E820_EXT node of
e820__reserve_setup_dataReserve all entries from the bootloader's extensible data nodes list,* because if present we are going to use it later on to fetch e820* entries from it:
e820__finish_early_paramsCalled after parse_early_param(), after early parameters (such as mem=)* have been processed, in which case we already have an E820 table filled in* via the parameter callback function(s), but it's not sorted and printed yet:
e820__memory_setupCalls e820__memory_setup_default() in essence to pick up the firmware/bootloader* E820 map - with an optional platform quirk available for virtual platforms* to override this method of boot environment processing:
