PM: Add initcall_debug style timing for suspend/resume

2009-12-15T19:42:06+00:00

In order to diagnose overall suspend/resume times, we need
basic instrumentation to break down the total time into per
device timing, similar to initcall_debug.

This patch adds the basic timing instrumentation, needed
for a scritps/bootgraph.pl equivalent or humans.
The bootgraph.pl program is still a work in progress, but
is far enough along to know that this patch is sufficient.

initcalls: Add early_initcall() for modules

2009-10-02T13:42:19+00:00

Complete the early_initcall() API by making it available in modules
too. To be used by the EDAC/MCE code.

x86: properly annotate alternatives.c

2009-08-21T22:30:12+00:00

Some of the NOPs tables aren't used on 64-bits, quite some code and
data is needed post-init for module loading only, and a couple of
functions aren't used outside that file (i.e. can be static, and don't
need to be exported).

The change to __INITDATA/__INITRODATA is needed to avoid an assembler
warning.

kernel: constructor support

2009-06-18T20:03:57+00:00

Call constructors (gcc-generated initcall-like functions) during kernel
start and module load.  Constructors are e.g.  used for gcov data
initialization.

Disable constructor support for usermode Linux to prevent conflicts with
host glibc.

fbdev: move logo externs to header file

2009-06-17T02:47:57+00:00

Now we have __initconst, we can finally move the external declarations for
the various Linux logo structures to .

James' ack dates back to the previous submission (way to long ago), when the
logos were still __initdata, which caused failures on some platforms with some
toolchain versions.

vmlinux.lds.h update

2009-06-14T20:10:41+00:00

Updated after review by Tim Abbott.
- Use HEAD_TEXT_SECTION
- Drop use of section-names.h and delete file
- Introduce EXIT_CALL

Deleting section-names.h required a few simple
updates of init.h

initconst adjustments

2009-06-09T20:37:43+00:00

- add .init.rodata to INIT_DATA, and group all initconst flavors
  together
- move strings generated from __setup_param() into .init.rodata
- add .*init.rodata to modpost's sets of init sections
- make modpost warn about references between meminit and cpuinit
  as well as memexit and cpuexit sections (as CPU and memory
  hotplug are independently selectable features)

Remove unused support code for refok sections.

2009-04-28T02:51:58+00:00

The old refok sections

  .text.init.refok
  .data.init.refok
  .exit.text.refok

have been deprecated since commit
312b1485fb509c9bc32eda28ad29537896658cb8.  After the other patches in
this patch series nothing is put in these sections, so clean things up
by eliminating all the remaining references to them.

Add new HEAD_TEXT_SECTION macro.

2009-04-26T16:20:38+00:00

This patch is preparation for replacing all uses of ".head.text" or
".text.head" in the kernel with macros, so that the section name can
later be changed without having to touch a lot of the kernel.

Since some linker scripts do more complex things than referencing
HEAD_TEXT, we add a HEAD_TEXT_SECTION macro that just contains the
actual name.

I've defined HEAD_TEXT_SECTION in a new header,
include/linux/section-names.h, so that this section name only needs to
appear in one place.  I anticipate creating similar macro structures
for a number of other section names.

The long-term goal here is to be able to change the kernel's magic
section names to those that are compatible with -ffunction-sections
-fdata-sections.  This requires renaming all magic sections with names
of the form ".text.foo".

Driver Core: early platform driver

2009-04-16T23:17:10+00:00

V3 of the early platform driver implementation.

Platform drivers are great for embedded platforms because we can separate
driver configuration from the actual driver.  So base addresses,
interrupts and other configuration can be kept with the processor or board
code, and the platform driver can be reused by many different platforms.

For early devices we have nothing today.  For instance, to configure early
timers and early serial ports we cannot use platform devices.  This
because the setup order during boot.  Timers are needed before the
platform driver core code is available.  The same goes for early printk
support.  Early in this case means before initcalls.

These early drivers today have their configuration either hard coded or
they receive it using some special configuration method.  This is working
quite well, but if we want to support both regular kernel modules and
early devices then we need to have two ways of configuring the same
driver.  A single way would be better.

The early platform driver patch is basically a set of functions that allow
drivers to register themselves and architecture code to locate them and
probe.  Registration happens through early_param().  The time for the
probe is decided by the architecture code.

See Documentation/driver-model/platform.txt for more details.
