[PATCH] prevent swsusp with PAE

2006-09-06T18:00:02+00:00

PAE + swsusp results in hard-to-debug crash about 50% of time during
resume.  Cause is known, fix needs to be ported from x86-64 (but we can't
make it to 2.6.18, and I'd like this to be worked around in 2.6.18).

[PATCH] Make suspend possible with a traced process at a breakpoint

2006-08-06T15:57:45+00:00

It should be possible to suspend, either to RAM or to disk, if there's a
traced process that has just reached a breakpoint.  However, this is a
special case, because its parent process might have been frozen already and
then we are unable to deliver the "freeze" signal to the traced process.
If this happens, it's better to cancel the freezing of the traced process.

gcc isn't smart enough, so help it.

[PATCH] swsusp: do not use memcpy for snapshotting memory

2006-07-10T20:24:22+00:00

swsusp should not use memcpy for snapshotting memory, because on some
architectures memcpy may increase preempt_count (i386 does this when
CONFIG_X86_USE_3DNOW is set).  Then, as a result, wrong value of preempt_count
is stored in the image.

Replace memcpy in copy_data_pages with an open-coded loop.

[PATCH] pm_trace is dangerous

2006-06-28T00:32:35+00:00

`off'.

Also beef up the help message a bit.

because not only do they apparently cause page faults on x86, the
infrastructure doesn't compile on powerpc.

Fix PM_TRACE dependency: works only on 32-bit x86 for now

2006-06-25T17:04:15+00:00

Not that x86-64 and other architecture support should be difficult to
add (trivial fixups to the data format and add the proper linker script
entry).
