4 years agonvmap: page pools: fix lockdep splat
Colin Cross [Wed, 13 Aug 2014 02:36:04 +0000]
nvmap: page pools: fix lockdep splat

lockdep complains about the alloc_page call under the pool lock
in nvmap_page_pool_init because the pool lock is also taken during
reclaim in nvmap_page_pool_shrink.  Rewrite nvmap_page_pool_init
to perform the allocation in PENDING_PAGES_SIZE chunks outside the
lock.  Also move the global pending_pages to a static copy in
nvmap_pp_do_background_zero_pages and a kcalloc'd array during
init to avoid conflicts when two threads try to use the same array.

4 years agonvmap: page pools: replace background allocator with background zeroer
Colin Cross [Tue, 12 Aug 2014 00:33:09 +0000]
nvmap: page pools: replace background allocator with background zeroer

The background allocator rapidly becomes useless once the system
has filled memory with cached pages.  It refuses to allocate when
free memory < 128MB (which it always is, the kernel is aiming to
keep very little free), and freed pages are not returned to the
page pool when zero_memory=1.

Remove the background allocator completely, and instead return
freed memory to the page pool in a separate list to be zeroed
in the background.  This results in a self-balancing pool of
memory available to graphics, and reduces presure on the kernel's
page allocator.  If the pool grows too big it will get reduced
by the shrinker.  If it gets too small, the next allocation will
fall back to the page allocator, and then later return those pages
to the pool.

Before this change incremental page pool hit rate reported by
/d/nvmap/pagepool/page_pool_hits vs. /d/nvmap/pagepool/page_pool_misses
goes to 0% after boot.  After this change it is near 100% for small
app launches and 75% for larger app launches.

Colin Cross [Mon, 11 Aug 2014 23:09:51 +0000]
nvmap: page pool: fix background thread

Fix a race condition in the background allocator where
wake_up_process could be called just before set_current_state
changed the state to TASK_INTERRUPTIBLE, causing the thread
not to wake.  Use a waitqueue instead.

Also make the background allocator nicer by marking it freezable
so it doesn't compete with suspend, and setting it SCHED_IDLE so
it only runs when no other threads want to run.

4 years agogk20a: Moved bind fecs to init_gr_support
Mahantesh Kumbar [Tue, 14 Oct 2014 12:14:34 +0000]
gk20a: Moved bind fecs to init_gr_support

-Moved bind fecs from work queue to init_gr_support.
-It makes all CPU->FECS communication to happen before
booting PMU, and after we boot PMU, only PMU talks to
FECS. So it removes possibility to race between CPU
and PMU talking to FECS.

video: tegra: host: gk20a: fix PDE update sequence

Current sequence :
- delete page tables memory
- update PDE entry and mark above page tables invalid

With this sequence, it is possible to have valid PDE entries
with already freed page table and this could lead us to
invalid memory accesses.

Fix this by switching the sequence as follows :
- update PDE entry and mark page tables invalid
- delete page tables memory
