* x86: move reserve_setup_data to setup.cYinghai Lu2008-07-081-2/+0
| | | | | | | | | | | | | | | | | | | | Ying Huang would like setup_data to be reserved, but not included in the no save range. Here we try to modify the e820 table to reserve that range early. also add that in early_res in case bootloader messes up with the ramdisk. other solution would be 1. add early_res_to_highmem... 2. early_res_to_e820... but they could reserve another type memory wrongly, if early_res has some resource reserved early, and not needed later, but it is not removed from early_res in time. Like the RAMDISK (already handled). Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Cc: andi@firstfloor.org Tested-by: Huang, Ying <ying.huang@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| * x86 boot: pass E820 memory map entries more than 128 via linked list of ↵Huang, Ying2008-07-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | setup data Because of the size limits of struct boot_params (zero page), the maximum number of E820 memory map entries can be passed to kernel is 128. As pointed by Paul Jackson, there is some machine produced by SGI with so many nodes that the number of E820 memory map entries is more than 128. To enabling Linux kernel on these system, a new setup data type named SETUP_E820_EXT is defined to pass additional memory map entries to Linux kernel. This patch is based on x86/auto-latest branch of git-x86 tree and has been tested on x86_64 and i386 platform.

* | x86: Honor 'quiet' command line option in real mode boot decompressor.Kristian Høgsberg2008-05-301-0/+1
|/ | | | | | | | | | This patch lets the early real mode code look for the 'quiet' option on the kernel command line and pass a loadflag to the decompressor. When this flag is set, we suppress the "Decompressing Linux... Parsing ELF... done." messages. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* x86, boot: add linked list of struct setup_dataHuang, Ying2008-04-261-0/+14
| | | | | | | | | | | This patch adds a field of 64-bit physical pointer to NULL terminated single linked list of struct setup_data to real-mode kernel header. This is used as a more extensible boot parameters passing mechanism.

* x86: EFI runtime service supportHuang, Ying2008-01-301-2/+3
| | | | | | | | | | | | | | | | | | | This patch adds basic runtime services support for EFI x86_64 system. The main file of the patch is the addition of efi_64.c for x86_64. This file is modeled after the EFI IA32 avatar. EFI runtime services initialization are implemented in efi_64.c. Some x86_64 specifics are worth noting here. On x86_64, parameters passed to EFI firmware services need to follow the EFI calling convention. For this purpose, a set of functions named efi_call<x> (<x> is the number of parameters) are implemented. EFI function calls are wrapped before calling the firmware service. The duplicated code between efi_32.c and efi_64.c is placed in efi.c to remove them from efi_32.c.

* Make asm-x86/bootparam.h includable from userspace.Rusty Russell2007-10-231-54/+54
| | | | | | | | | | | To actually write a bootloader (or, say, the lguest launcher) currently requires duplication of these structures. Making them includable from userspace is much nicer. We merge the common userspace-required definitions of e820_32/64.h into e820.h for export. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* update boot spec to 2.07Rusty Russell2007-10-221-2/+7
| | | | | | | | | | | | | | | | | | | Updates for version 2.07 of the boot protocol. This includes: load_flags.KEEP_SEGMENTS- flag to request/inhibit segment reloads hardware_subarch - what subarchitecture we're booting under hardware_subarch_data - per-architecture data The intention of these changes is to make booting a paravirtualized kernel work via the normal Linux boot protocol.
