Annouce: Initial SWSUSP 2.4 port to 2.5 available.

[Nigel Cunningham]

Hi all.

It is with delight that I write to announce the first release of the
port of Software Suspend for 2.4 to 2.5. This version has all the
functionality of the 2.4 version beta19-17 - the current development
version for 2.4.  This includes the following enhancements over the
version currently included in the 2.5 kernel:

- HighMem support
- Multiple swap partiton support
- Ability to cancel a suspend by pressing ALT.
- Ability to save what is close a perfect image image of RAM (resulting
in a very fast, responsive system on resume - assumes enough swap
available to store your full image)
- Extensive debugging capabilities
- Fast and reliable (extensive testing done under 2.4).

There are issues still to be dealt with, but these should not in any way
interfere with testing at this stage. They are:

- 2 page flags currently used: to be converted to dynamically allocated
bitmaps
- Interaction with S3 support to be tested and worked on (some common
files affected, S3 support not tested).
- Code cleanups still to be done in some places.

You can find the patch against 2.5.66 on
www.sourceforge.net/projects/swsusp. It's in the swsusp-devel section at
the bottom of the list.

Regards,

Nigel

I'm glad that you have done this work, and I look forward to merging it 
with the power management infrastructure work I have been doing. However, 
there are several outstanding issues.

I will not take the code which still relies on the page flag bits. I look
forward to your dynamic bitmap implementation. 

As for the current patch, I was unable to test its actual functionality, 
which I will get to in a moment. 

First, I request that you please name the patches something sensible that 
won't collide with anything else, like swsusp-2.5.66-<n>.diff, not 
'patch-2.5.66-<n>.diff'.

Also, please make it explicitly clear which patch(es) are needed for 
download. On the sourceforge site, both -01 and -02 are highlighted as 
current, though they appear to different versions of the same thing. 

I'm glad to hear that you have completed the full port, but many people 
appreciate incremental patches, especially if the cumulative changes 
touch multiple parts of the kernel. Please consider breaking the one large 
patch into multiple, easily digestible, chunks. 

Finally, with either patch, there are unresolved symbols:

arch/i386/kernel/built-in.o: In function `do_suspend_lowlevel':
arch/i386/kernel/built-in.o(.data+0x1644): undefined reference to `save_processor_state'
arch/i386/kernel/built-in.o(.data+0x164a): undefined reference to `saved_context_esp'
arch/i386/kernel/built-in.o(.data+0x164f): undefined reference to `saved_context_eax'
arch/i386/kernel/built-in.o(.data+0x1655): undefined reference to `saved_context_ebx'
arch/i386/kernel/built-in.o(.data+0x165b): undefined reference to `saved_context_ecx'
arch/i386/kernel/built-in.o(.data+0x1661): undefined reference to `saved_context_edx'
arch/i386/kernel/built-in.o(.data+0x1667): undefined reference to `saved_context_ebp'
arch/i386/kernel/built-in.o(.data+0x166d): undefined reference to `saved_context_esi'
arch/i386/kernel/built-in.o(.data+0x1673): undefined reference to `saved_context_edi'
arch/i386/kernel/built-in.o(.data+0x167a): undefined reference to `saved_context_eflags'

The fix is likely trivial, but it is annoying that it happens in the first 
place.

Thanks,

Thats S3 support. Likely Nigel has not S3 compiled in and you
have. Disalbe CONFIG_ACPI_SLEEP as a workaround.

That works.
