drm/omap: gem: Fix mm_list locking

2018-06-28T10:41:05+00:00

- None of the list walkings where protected.

- Switch to a mutex since the list walking at device resume time can
  sleep when pinning buffers through the tiler.

Only thing we need to be careful with here is that while we walk the
list we can't unreference any gem objects, since the final unref would
result in a recursive deadlock. But the only functions that walk the
list is the device resume and debugfs dumping, so all safe.

drm/omap: gem: Replace struct_mutex usage with omap_obj private lock

2018-06-28T10:41:05+00:00

The DRM device struct_mutex is used to protect against concurrent GEM
object operations that deal with memory allocation and pinning. All
those operations are local to a GEM object and don't need to be
serialized across different GEM objects. Replace the struct_mutex with
a local omap_obj.lock or drop it altogether where not needed.

drm: omapdrm: Remove filename from header and fix copyright tag

2017-12-19T09:21:32+00:00

Having the filename in the header serves little purpose and is
often wrong after renames as it is here in several places, just
drop it from all omapdrm files.

While we are here unify the copyright tags to the TI recommended style.

drm/omap: Remove omap_debugfs_cleanup()

2017-01-27T14:25:53+00:00

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so the drm_driver.debugfs_cleanup callback is not
needed.

drm/mm: Convert to drm_printer

2016-12-30T11:08:28+00:00

Including all drivers. I thought about keeping small compat functions
to avoid having to change all drivers. But I really like the
drm_printer idea, so figured spreading it more widely is a good thing.

v2: Review from Chris:
- Natural argument order and better name for drm_mm_print.
- show_mm() macro in the selftest.

drm/omap: include linux/seq_file.h where needed

2016-05-31T05:30:14+00:00

The omapdrm driver relies on this header to be included
implicitly, but this does not always work, and I get
this error in randconfig builds:

gpu/drm/omapdrm/dss/hdmi_phy.c: In function 'hdmi_phy_dump':
gpu/drm/omapdrm/dss/hdmi_phy.c:34:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]
gpu/drm/omapdrm/dss/hdmi_wp.c: In function 'hdmi_wp_dump':
gpu/drm/omapdrm/dss/hdmi_wp.c:26:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]

gpu/drm/omapdrm/dss/hdmi_pll.c:30:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]

This adds the #include statements in all files that have
a seq_printf statement.

drm: store the gem vma offset manager in a typed pointer

2014-01-14T02:38:32+00:00

This was hidden in a generic void * dev->mm_private. But only ever
used for gem. But thanks to this fake generic pretension no one
noticed that Rob's drm drivers are now all broken.

So just give the offset manager a type pointer and fix up msm, omapdrm
and tilcdc.

v2: Fixup compile fail.

v3: Fixup rebase fail that David spotted.
