x86: consolidate header guards

2008-07-22T19:31:34+00:00

This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum

x86: make __{save,restore}_processor_state static

2008-01-30T12:31:23+00:00

.. allowing to remove their declarations from a global include file (the symbols don't exist for anything but x86). Likewise for 64-bits' fix_processor_context(), just that that one was properly declared in an arch-specific header.

x86: hibernation: document __save_processor_state() on x86

2008-01-30T12:30:04+00:00

Document the fact that __save_processor_state() has to save all CPU registers referred to by the kernel in case a different kernel is used to load and restore a hibernation image containing it. Sigend-off-by: Rafael J. Wysocki Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

x86: Save registers in saved_context during suspend and hibernation

2007-10-23T20:37:24+00:00

During hibernation and suspend on x86_64 save CPU registers in the saved_context structure rather than in a handful of separate variables. Signed-off-by: Rafael J. Wysocki Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

Hibernation: Arbitrary boot kernel support on x86_64

2007-10-18T21:37:19+00:00

Make it possible to restore a hibernation image on x86_64 with the help of a kernel different from the one in the image. The idea is to split the core restoration code into two separate parts and to place each of them in a different page. The first part belongs to the boot kernel and is executed as the last step of the image kernel's memory restoration procedure. Before being executed, it is relocated to a safe page that won't be overwritten while copying the image kernel pages. The final operation performed by it is a jump to the second part of the core restoration code that belongs to the image kernel and has just been restored. This code makes the CPU switch to the image kernel's page tables and restores the state of general purpose registers (including the stack pointer) from before the hibernation. The main issue with this idea is that in order to jump to the second part of the core restoration code the boot kernel needs to know its address. However, this address may be passed to it in the image header. Namely, the part of the image header previously used for checking if the version of the image kernel is correct can be replaced with some architecture specific data that will allow the boot kernel to jump to the right address within the image kernel. These data should also be used for checking if the image kernel is compatible with the boot kernel (as far as the memory restroration procedure is concerned). It can be done, for example, with the help of a "magic" value that has to be equal in both kernels, so that they can be regarded as compatible. Signed-off-by: Rafael J.
