From ac5c24ec1e983313ef0015258fba6f630e54e7cf Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 20 Sep 2010 19:44:56 +0200 Subject: PM / Hibernate: Make default image size depend on total RAM size The default hibernation image size is currently hard coded and euqal to 500 MB, which is not a reasonable default on many contemporary systems. Make it equal 2/5 of the total RAM size (this is slightly below the maximum, i.e. 1/2 of the total RAM size, and seems to be generally suitable). Signed-off-by: Rafael J. Wysocki Tested-by: M.
