drm/vmwgfx: Free hash table allocated by cmdbuf managed res mgr

2017-07-05T12:41:39+00:00

commit 82fcee526ba8ca2c5d378bdf51b21b7eb058fe3a upstream.

The hash table created during vmw_cmdbuf_res_man_create was
never freed. This causes memory leak in context creation.
Added the corresponding drm_ht_remove in vmw_cmdbuf_res_man_destroy.

Tested for memory leak by running piglit overnight and kernel
memory is not inflated which earlier was.

    drm: Tighten locking in drm_mode_getconnector

I reordered the logic a bit in that IOCTL, but that broke userspace
since it'll get the new mode list, but not the new property values.
Fix that again.

v2: Fix up the error path handling when copy_to_user for the modes
failes (Dhinakaran).

drm/vc4: Fix OOPSes from trying to cache a partially constructed BO.

commit ca39b449f6d03e8235969f12f5dd25b8eb4304d6 upstream.

If a CMA allocation failed, the partially constructed BO would be
unreferenced through the normal path, and we might choose to put it in
the BO cache.  If we then reused it before it expired from the cache,
the kernel would OOPS.

drm/i915: Do not sync RCU during shrinking

2017-06-24T05:06:15+00:00

commit 4681ee21d62cfed4364e09ec50ee8e88185dd628 upstream.

Due to the complex dependencies between workqueues and RCU, which
are not easily detected by lockdep, do not synchronize RCU during
shrinking.

On low-on-memory systems (mem=1G for example), the RCU sync leads
to all system workqueus freezing and unrelated lockdep splats are
displayed according to reports. GIT bisecting done by J. R.
Okajima points to the commit where RCU syncing was extended.

RCU sync gains us very little benefit in real life scenarios
where the amount of memory used by object backing storage is
dominant over the metadata under RCU, so drop it altogether.

 " Yeeeaah, if core could just, go ahead and reclaim RCU
   queues, that'd be great. "

  - Chris Wilson, 2016 (0eafec6d3244)

v2: More information to commit message.
v3: Remove "grep _rcu_" escapee from i915_gem_shrink_all (Andrea)
