Software suspend under Linux

Software suspend optional patches

Together with the principal patch, you will find here some little patches that may help you using software suspension. Those patches will eventually be incorporated in the main tree so please report if you think one of these patches is useful.

apm .GZ 17/08/2012 12:41
677 octets
This patch replaces the apm standby call by software suspension procedure. This should no more be useful since beta9 patch provides its own user level and scriptable interface.
apmbis .GZ 17/08/2012 12:41
739 octets
This patch replaces the apm suspend call by software suspension procedure. This should no more be useful since beta9 patch provides its own user level and scriptable interface.

Obsoletes software suspend optional patches

Those patches should not be useful any more.
agpgart .GZ 17/08/2012 12:41
1089 octets
This patch may be useful if your graphic chipset uses agpgart module (for instance i8xx intel chipsets). It should help resume the X session correctly. This patch needs some testing and improvements for other chipsets. It should take place more naturally in the kernel itself.
This patch should also work with Alan Cox's 2.4.19-pre7-ac3 kernel tree.
memeat .GZ 17/08/2012 12:41
1081 octets
When suspending you may lack enough free pages to perform the suspension. This patch makes the page freeing more agressive. Please report if you need this patch for your configuration.
Since beta5, this patch is now incorporated.
nodebug .GZ 17/08/2012 12:41
435 octets
This patch disables the debugging features (should suspend and resume faster) and makes the machine halt instead of rebooting.
makefile .GZ 17/08/2012 12:41
274 octets
This patch simply adds -swsusp to the kernel version. This may be useful if you want to check using "uname -r" whether you currently run a patched kernel or not.
reiserfs .GZ 17/08/2012 12:41
545 octets
This patch may be needed for suspending with a mounted reiserfs filesystem. If you need it and it works for your configuration, please report.
This patch is now incorporated in main patch. It is also present in Alan Cox's 2.4.19-pre7-ac3 kernel tree.
two passes .GZ 17/08/2012 12:41
1933 octets
This patch is against beta3 software suspend version.
This patch makes the stopping of tasks in two passes. First pass is for the normal tasks, second one for some kernel threads involved in filesystems. This patch may or may not be useful to prevent suspension hanging or unended loop in ide_disks_suspend. If you have to use it, please report your configuration.
Since this patch seems useless, it is no more maintained.
