[PATCH] USB: correct the USB info in Documentation/power/swsusp.txt 2006-06-21T22:04:11+00:00 David Brownell david-b@pacbell.net 2006-05-17T00:33:14+00:00 b9827e4b29edb4af1481b75efdf9ea2d8a7ffc96 The swsusp.txt documentation harshes confusingly on USB, and this patch addresses the issue. It's harsh because it blames USB for some issues that are generic to all drivers -- especially those supporting removable media -- and it's confusing since it says that USB has the issue with "suspend" not just swsusp ... while in reality, USB doesn't have the issue when real system suspend states are used.

[PATCH] suspend: Documentation update for IBM Thinkpad X30 2006-04-28T15:33:49+00:00 Antonino A.

For the IBM Thinkpad X30 using vesafb as the console driver, successful resume from S3 requires option acpi_sleep=s3_bios,s3_mode. Update documentation. I would presume that, in any hardware, using vesafb as the console driver will require as a minimum s3_mode.

[PATCH] swsusp: userland interface 2006-03-23T15:38:07+00:00 Rafael J. Wysocki rjw@sisk.pl 2006-03-23T11:00:03+00:00 6e1819d615f24ce0726a7d0bd3dd0152d7b21654 This patch introduces a user space interface for swsusp. The interface is based on a special character device, called the snapshot device, that allows user space processes to perform suspend and resume-related operations with the help of some ioctls and the read()/write() functions.  Additionally it allows these processes to allocate free swap pages from a selected swap partition, called the resume partition, so that they know which sectors of the resume partition are available to them. The interface uses the same low-level system memory snapshot-handling functions that are used by the built-it swap-writing/reading code of swsusp. The interface documentation is included in the patch. The patch assumes that the major and minor numbers of the snapshot device will be 10 (ie. misc device) and 231, the registration of which has already been requested. Signed-off-by: Rafael J.
