x86 boot: remove some unused extern function declarations

2008-05-25T08:55:10+00:00

Remove three extern declarations for routines that don't exist. Fix a typo in a comment. Signed-off-by: Paul Jackson Signed-off-by: Ingo Molnar

x86: EFI_PAGE_SHIFT fix

2008-04-19T17:19:54+00:00

Make x86 EFI code works when EFI_PAGE_SHIFT != PAGE_SHIFT. The memrage_efi_to_native() provided in this patch can be used on other EFI platform such as IA64 too. This patch has been tested on Intel x86_64 platform with EFI 64/32 firmware. Signed-off-by: Huang Ying Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

kexec: add BSS to resource tree

2007-10-22T15:13:19+00:00

Add the BSS to the resource tree just as kernel text and kernel data are in the resource tree. The main reason behind this is to avoid crashkernel reservation in that area. While it's not strictly necessary to have the BSS in the resource tree (the actual collision detection is done in the reserve_bootmem() function before), the usage of the BSS resource should be presented to the user in /proc/iomem just as Kernel data and Kernel code. Note: The patch currently is only implemented for x86 and ia64 (because efi_initialize_iomem_resources() has the same signature on i386 and ia64).

EFI: warn only for pre-1.00 system tables

2007-05-08T18:15:10+00:00

We used to warn unless the EFI system table major revision was exactly 1. But EFI 2.00 firmware is starting to appear, and the 2.00 changes don't affect anything in Linux. Signed-off-by: Bjorn Helgaas Cc: Andi Kleen Cc: "Luck, Tony" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] i386: Preserve EFI run time regions with memmap parameter

2006-12-07T01:14:11+00:00

When using memmap kernel parameter in EFI boot we should also add to memory map memory regions of runtime services to enable their mapping later. AK: merged and cleaned up the patch Signed-off-by: Artiom Myaskouvskey Signed-off-by: Andi Kleen

[PATCH] i386: call efi_get_time during suspend

2006-12-07T01:14:11+00:00

Function efi_get_time called not only during init kernel phase but also during suspend (from get_cmos_time). When it is called from get_cmos_time the corresponding runtime service should be called in virtual and not in physical mode.

[IA64] rework memory attribute aliasing

2006-05-08T23:32:05+00:00

This closes a couple holes in our attribute aliasing avoidance scheme: - The current kernel fails mmaps of some /dev/mem MMIO regions because they don't appear in the EFI memory map. This keeps X from working on the Intel Tiger box. - The current kernel allows UC mmap of the 0-1MB region of /sys/.../legacy_mem even when the chipset doesn't support UC access. This causes an MCA when starting X on HP rx7620 and rx8620 boxes in the default configuration. There's more detail in the Documentation/ia64/aliasing.txt file this adds, but the general idea is that if a region might be covered by a granule-sized kernel identity mapping, any access via /dev/mem or mmap must use the same attribute as the identity mapping. Otherwise, we fall back to using an attribute that is supported according to the EFI memory map, or to using UC if the EFI memory map doesn't mention the region.

[PATCH] EFI: keep physical table addresses in efi structure

2006-03-26T16:56:54+00:00

Almost all users of the table addresses from the EFI system table want physical addresses. So rather than doing the pa->va->pa conversion, just keep physical addresses in struct efi. This fixes a DMI bug: the efi structure contained the physical SMBIOS address on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap() on a virtual address on ia64. This is essentially the same as an earlier patch by Matt Tolentino: http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2 except that this changes all table addresses, not just ACPI addresses. Matt's original patch was backed out because it caused MCAs on HP sx1000 systems. That problem is resolved by the ioremap() attribute checking added for ia64.
