2007-07-12Remove old i386 setup codeH. Peter Anvin
This removes the old i386 setup code. This is done as a separate patch to avoid breaking git bisect as some of the i386 code was also used by the old x86-64 code. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-07-12Use the new x86 setup code for x86-64; unify with i386H. Peter Anvin
This unifies arch/*/boot (except arch/*/boot/compressed) between i386 and x86-64, and uses the new x86 setup code for x86-64 as well. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-07-12Use the new x86 setup code for i386H. Peter Anvin
This patch hooks the new x86 setup code into the Makefile machinery. It also adapts boot/tools/build.c to a two-file (as opposed to three-file) universe, and simplifies it substantially. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-07-12Video mode probing support for the new x86 setup codeH. Peter Anvin
Video mode probing for the new x86 setup code. This code breaks down different drivers into modules. This code deliberately drops support for a lot of the vendor-specific mode probing present in the assembly version, since a lot of those probes have been found to be stale in current versions of those chips -- frequently, support for those modes have been dropped from recent video BIOSes due to space constraints, but the video BIOS signatures are still the same. However, additional drivers should be extremely straightforward to plug in, if desirable. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-07-12Make struct boot_params a real structure, and remove obsolete fieldsH. Peter Anvin
Make struct boot_params a real structure, and remove the handling of some obsolete fields, in particular hd*_info, which was only used by the ST-506 driver, and likely to be wrong for that driver on any modern BIOS.

2007-07-12Define zero-page offset 0x1e4 as a scratch field, and use itH. Peter Anvin
The relocatable kernel code needs a scratch field for the decompressor to determine its own location. It was using a location inside struct screen_info; reserve a free location and document it as scratch instead. Signed-off-by: H.

2007-07-12Use a new CPU feature word to cover features that are spread aroundVenki Pallipadi
Some Intel features are spread around in different CPUID leafs like 0x5, 0x6 and 0xA. Make this feature detection code common across i386 and x86_64. Display Intel Dynamic Acceleration feature in /proc/cpuinfo. This feature will be enabled automatically by current acpi-cpufreq driver. Refer to Intel Software Developer's Manual for more details about the feature. Thanks to hpa (H Peter Anvin) for the making the actual code detecting the scattered features data-driven.

2007-07-12Clean up struct screen_info (<linux/screen_info.h>)H. Peter Anvin
struct screen_info has unaligned members, it needs to be packed. In the process, fix the naming of some of the members, which don't belong in this structure but are part of it anyway. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-07-12x86 Kconfig: change X86_MINIMUM_CPU_MODEL to X86_MINIMUM_CPU_FAMILYH. Peter Anvin
The X86_MINIMUM_CPU_MODEL name isn't really right, so change it to X86_MINIMUM_CPU_FAMILY. Also, the default minimum should be 3, not 0. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-07-12Unify the CPU features vectors between i386 and x86-64H. Peter Anvin
Unify the handling of the CPU features vectors between i386 and x86-64. This also adopts the collapsing of features which are required at compile-time into constant tests from x86-64 to i386. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-07-12hd.c: remove BIOS/CMOS queriesH. Peter Anvin
An ST-506 disk these days is pretty much someone trying to pull ancient data using an auxilliary controller. Pulling data from the BIOS or CMOS is just plain wrong, since it's likely to be the primary OS disk... and would be user-entered data anyway. Instead, require the user enters it on the command line.

2007-07-12[MIPS] SMTC: Interrupt mask backstop hackKevin D. Kissell
To support multiple TC microthreads acting as "CPUs" within a VPE, VPE-wide interrupt mask bits must be specially manipulated during interrupt handling. To support legacy drivers and interrupt controller management code, SMTC has a "backstop" to track and if necessary restore the interrupt mask. This has some performance impact on interrupt service overhead. Disable it only if you know what you are doing. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
