drm: move drm_class into drm_sysfs.c

2015-09-09T13:05:17+00:00

Right now, drm_sysfs_create() returns the newly allocated "struct class"
to the caller (which is drm_core_init()), which then has to set the
global variable 'drm_class'. During cleanup, though, we call
drm_sysfs_destroy() which implicitly uses the global 'drm_class'. This is
confusing, as ownership of the global 'drm_class' is non-obvious.

This patch changes drm_sysfs_create() to drm_sysfs_init() and makes it
initialize the 'drm_class' object directly, rather than returning it.
This way, both drm_sysfs_init() and drm_sysfs_destroy() work in a similar
fashion and manage the global drm class.

drm: simplify authentication management

2015-05-05T07:45:57+00:00

The magic auth tokens we have are a simple map from cyclic IDs to drm_file
objects. Remove all the old bulk of code and replace it with a simple,
direct IDR.

The previous behavior is kept. Especially calling authmagic multiple times
on the same magic results in EINVAL except on the first call. The only
difference in behavior is that we never allocate IDs multiple times as
long as a client has its FD open.

v2:
 - Fix return code of GetMagic()
 - Use non-cyclic IDR allocator
 - fix off-by-one in "magic > INT_MAX" sanity check

v3:
 - drop redundant "magic > INT_MAX" check

drm/info: Remove unused code

2014-12-16T17:44:34+00:00

Commit 28a62277e06f ("drm: Convert proc files to seq_file and introduce
debugfs") converted /proc files to debugfs and in the process dropped
the entry for the vblank statistics. Since that file has been gone for
almost five years, there is no use to keep the code that provides the
file's content around.

drm: Move internal debugfs functions to drm_internal.h

2014-09-24T01:43:35+00:00

In my header cleanup I've missed the debugfs functions completely.

Somehow I've missed these three, fix this up asap. Plus move
drm_master_create since while at it.

drm: Move drm_vm_open_locked into drm_internal.h

2014-09-24T01:43:20+00:00

Leftover from my previous header cleanup.

This depends upon the patch to rework exynos mmap support, otherwise
it'll break exynos.

drm: move drm_mmap to

2014-09-24T01:43:07+00:00

Now that we've removed the copypasted users in gem/ttm we can
relegate the legacy buffer mapping support to where it belongs.
Also give it the proper drm_legacy_ prefix.

While at it statify drm_mmap_locked, somehow I've missed that in my
previous header rework.

drm: unexport drm_global_mutex

2014-09-12T09:19:47+00:00

Drivers really, really have no business even looking at this lock. And
thankfully they don't.

So unexport it and move the declaration to drm_internal.h.

drm: Move piles of functions from drmP.h to drm_internal.h

2014-09-12T09:16:29+00:00

This way drivers can't grow crazy ideas any more, and it also
helps a bit in reviewing EXPORT_SYMBOLS.

v2: Even more stuff. Unfortunately we can't move drm_vm_open_locked
because exynos does some horrible stuff with it.
