It turns out that the\namount of memory allocated by radeon during hibernation (and\npresumably during system suspend too) depends on the utilization of\nthe GPU (e.g. hibernating while there are two KDE 4 sessions with\ncompositing enabled causes radeon to allocate more memory than for\none KDE 4 session).\n\nIn principle it should be possible to use image_size to make the\nmemory preallocation mechanism free enough memory for the radeon\ndriver, but in practice it is not easy to guess the right value\nbecause of the way the preallocation code uses image_size. For this\nreason, it seems reasonable to allow users to control the amount of\nmemory reserved for driver allocations made after the hibernate\npreallocation, which currently is constant and amounts to 1 MB.\n\nIntroduce a new sysfs file, /sys/power/reserved_size, whose value\nwill be used as the amount of memory to reserve for the\npost-preallocation reservations made by device drivers, in bytes.\nFor backwards compatibility, set its default (and initial) value to\nthe currently used number (1 MB).\n\nReferences: https://bugzilla.kernel.org/show_bug.cgi?id\u003d34102\nReported-and-tested-by: Martin Steigerwald \u003cMartin@Lichtvoll.de\u003e\nSigned-off-by: Rafael J.

The broadcast device\nserves as a backup for per cpu timers which stop in deeper\nC-states. To avoid starvation of the cpus which might be in idle and\ndepend on broadcast mode it marks the other cpus as broadcast active\nand sets the brodcast expiry value of those cpus to the next tick.\n\nThe oneshot mode broadcast bit for the other cpus is sticky and gets\nonly cleared when those cpus exit idle. If a cpu was not idle while\nthe bit got set in consequence the bit prevents that the broadcast\ndevice is armed on behalf of that cpu when it enters idle for the\nfirst time after it switched to oneshot mode.\n\nIn most cases that goes unnoticed as one of the other cpus has usually\na timer pending which keeps the broadcast device armed with a short\ntimeout. Now if the only cpu which has a short timer active has the\nbit set then the broadcast device will not be armed on behalf of that\ncpu and will fire way after the expected timer expiry. In the case of\nChristians bug report it took ~145 seconds which is about half of the\nwrap around time of HPET (the limit for that device) due to the fact\nthat all other cpus had no timers armed which expired before the 145\nseconds timeframe.\n\nThe solution is simply to clear the broadcast active bit\nunconditionally when a cpu switches to oneshot mode after the first\ncpu switched the broadcast device over.
