      [PATCH] swsusp: use less memory during resume · 968808b8
      由 Rafael J. Wysocki 提交于 
      Make swsusp allocate only as much memory as needed to store the image data
and metadata during resume.

Without this patch swsusp additionally allocates many page frames that will
conflict with the "original" locations of the image data and are considered
as "unsafe", treating them as "eaten" pages (ie.  allocated but unusable).

The patch makes swsusp allocate as many pages as it'll need to store the
data read from the image in one shot, creating a list of allocated "safe"
pages, and use the observation that all pages allocated by it are marked
with the PG_nosave and PG_nosave_free flags set.   Namely, when it's about
to load an image page, swsusp can check whether the page frame
corresponding to the "original" location of this page has been allocated
(ie.  if the page frame has the PG_nosave and PG_nosave_free flags set) and
if so, it can load the page directly into this page frame.   Otherwise it
uses an allocated "safe" page from the list to store the data that will be
copied to their "original" location later on.

This allows us to save many page copyings and page allocations during
resume and in the future it may allow us to load images greater than 50% of
the normal zone.

      [PATCH] swsusp: take lowmem reserves into account · a938c356
      由 Rafael J. Wysocki 提交于 
      swsusp allocates memory from the normal zone, so it cannot use lowmem
reserve pages from the lower zones.  Therefore it should not count these
pages as available to it.

      [PATCH] swsusp: add architecture special saveable pages support · ce4ab001
      由 Shaohua Li 提交于 
      1. Add architecture specific pages save/restore support.  Next two patches
   will use this to save/restore 'ACPI NVS' pages.

2. Allow reserved pages 'nosave'.  This could avoid save/restore BIOS
   reserved pages.

      [PATCH] swsusp: rework memory shrinker · d6277db4
      由 Rafael J. Wysocki 提交于 
      Rework the swsusp's memory shrinker in the following way:

- Simplify balance_pgdat() by removing all of the swsusp-related code
  from it.

- Make shrink_all_memory() use shrink_slab() and a new function
  shrink_all_zones() which calls shrink_active_list() and
  shrink_inactive_list() directly for each zone in a way that's optimized
  for suspend.

In shrink_all_memory() we try to free exactly as many pages as the caller
asks for, preferably in one shot, starting from easier targets.   If slab
caches are huge, they are most likely to have enough pages to reclaim.
 The inactive lists are next (the zones with more inactive pages go first)
etc.

Each time shrink_all_memory() attempts to shrink the active and inactive
lists for each zone in 5 passes.   In the first pass, only the inactive
lists are taken into consideration.   In the next two passes the active
lists are also shrunk, but mapped pages are not reclaimed.   In the last
two passes the active and inactive lists are shrunk and mapped pages are
reclaimed as well.  The aim of this is to alter the reclaim logic to choose
the best pages to keep on resume and improve the responsiveness of the
resumed system.
