[media] v4l: vb2-dma-contig: fix vb2_get_vma()

nvmap expects that same VMA is opened and closed to disallow
memory leaks. So, nvmap panics if a previously non-existent vma
is being closed through it.

Hence modify the sequence in vb2_get_vma() to
open the vma_copy before returning it. This way nvmap sees that
the vma_copy exists in its list and will close the vma.

3 years agopipe: iovec: Fix memory corruption when retrying atomic copy as non-atomic
Ben Hutchings [Tue, 16 Jun 2015 21:11:06 +0000]
pipe: iovec: Fix memory corruption when retrying atomic copy as non-atomic

pipe_iov_copy_{from,to}_user() may be tried twice with the same iovec,
the first time atomically and the second time not.  The second attempt
needs to continue from the iovec position, pipe buffer offset and
remaining length where the first attempt failed, but currently the
pipe buffer offset and remaining length are reset.  This will corrupt
the piped data (possibly also leading to an information leak between
processes) and may also corrupt kernel memory.

This was fixed upstream by commits f0d1bec9d58d ("new helper:
copy_page_from_iter()") and 637b58c2887e ("switch pipe_read() to
copy_page_to_iter()"), but those aren't suitable for stable.  This fix
for older kernel versions was made by Seth Jennings for RHEL and I
have extracted it from their update.

Current single shot mode, pixel parser is disabled after capture one

 - arm single shot bit to start capture
 - for the last frame, wait for MWA_DONE syncpoint to make sure capture
   finished.

With optimized single shot mode, frame rate is about 4208x3120 @ 24fps
for IMX135 and 1920x1080 @ 30fps for AR0261.

xhci: tegra: run firmware log thread only if need

Driver doesn't need to run a kernel thread to collect firmware log
if release build firmware is loaded. Only debug build firmware is
capable of generating logs. This commit checks firmware CFGTBL to

video : hdmi: Add more checks in mode filter

While programming DC controller it is decided at runtime
if a particular mode can be satisfied. This check relies
on the parent pixel clock settings. This patch adds same
check in the mode filter function for HDMI, eliminating
entries from modelist which will not be supported.

video: tegra: hdmi: Fix potential crash when setting up HDMI

The HDMI state machine registers an IRQ handler before all the resources
it needs are available. Ideally the IRQ handler should be registered
later, however it would mean a quite large change. Instead we just add
some check to avoid running the state machine as long as the
framebuffer hasn't been registered.
While at it also prevent scheduling the state machine if it hasn't been
initialized yet.

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.

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.

Colin Cross [Fri, 8 Aug 2014 02:35:35 +0000]
nvmap: replace page pool array with a list

struct page already has a list node that is available to use by
whoever got the page with alloc_page.  Use it to keep the free
pages in the pool in a list instead of a circular buffer in an
array.
