Lukas Wunner 8e5de1d8c3 drm/radeon: Spell vga_switcheroo consistently
Currently everyone and their dog has their own favourite spelling
for vga_switcheroo. This makes it hard to grep dmesg for log entries
relating to vga_switcheroo. It also makes it hard to find related
source files in the tree.

vga_switcheroo.c uses pr_fmt "vga_switcheroo". Use that everywhere.

Thierry Reding cf6483050e drm/irq: Add drm_crtc_vblank_count_and_time()
This function is the KMS native variant of drm_vblank_count_and_time().
It takes a struct drm_crtc * instead of a struct drm_device * and an
index of the CRTC.

Eventually the goal is to access vblank data through the CRTC only so
that the per-CRTC data can be moved to struct drm_crtc.

Keep the fb_id, which means that any application exiting without
unsetting the framebuffer from all planes will preserve its contents.

This is similar to preserving the initial framebuffer, except all

Maarten Lankhorst 1380313281 drm/core: Preserve the framebuffer after removing it.
Previously RMFB and fd close chose to disable any plane that had
an active framebuffer from this file. If it was a primary plane the
crtc was disabled. However the fbdev code or any system compositor
should restore the planes anyway so there's no need to do it twice.

The old fb_id is zero'd, so there's no danger of being able to
restore the fb from fb_id.

Ville Syrjälä 4dfd64862f drm: Use vblank timestamps to guesstimate how many vblanks were missed
When lacking am accurate hardware frame counter, we can fall back to
using the vblank timestamps to guesstimagte how many vblanks have
elapsed since the last time the vblank counter was updated.

Take the oppostunity to unify the vblank_disable_and_save() and
drm_handle_vblank_events() to call the same function
(drm_update_vblank_count()) to perform the vblank updates.

If the hardware/driver has an accurate frame counter use it instead of
the timestamp based guesstimate. If the hardware/driver has neither
a frame counter nor acurate vblank timestamps, we fall back to assuming
that each drm_handle_vblank_events() should increment the vblank count
by one.

Ville Syrjälä 3bb403bf42 drm: Stop using linedur_ns and pixeldur_ns for vblank timestamps
linedur_ns, and especially pixeldur_ns are becoming rather inaccurate
to be used for the vblank timestamp correction. With 4k@60 the pixel
duration is already below 2ns, so the amount of error due to the
truncation to nanoseconds is introducing quite a bit of error.

We can avoid such problems if we instead calculate the timestamp
delta_ns directly from the dislay timings, avoiding the use of
these intermediate truncated values.

Matt Roper 942840371c drm/fbdev: Update legacy plane->fb refcounting for atomic restore
Starting with commit

        commit 28cc504e8d
        Author: Rob Clark <robdclark@gmail.com>
        Date:   Tue Aug 25 15:36:00 2015 -0400

            drm/i915: enable atomic fb-helper

I've been seeing some panics on i915 when the DRM master shuts down that appear
to be caused by using an already-freed framebuffer (i.e., we're unexpectedly
dropping our initial FB's reference count to 0 and freeing it, which causes a
crash when we try to restore it later).  Digging deeper, the state FB
refcounting is working as expected, but we seem to be missing proper
refcounting on the legacy plane->fb pointers in the new atomic fbdev code.

Tracking plane->old_fb and then doing a ref/unref at the end of the
fbdev restore like we do in the legacy ioctl's ensures we don't miscount
references on plane->fb and avoids the panics.

v2 from Daniel:

Really do what the atomic ioctl does:
- Also update plane->fb and plane->crtc.
- Clear out plane->old_fb on failures too.

v3: git add everything. Oops.

v4: Also clear old_fb in all other failure paths, spotted by David.

This should be harmless.
Vmware will, due to old infrastructure reasons, be using a privileged
control client to supply GUI layout information rather than obtaining
it from the device. That control client will be needing access to DRM
version information.

    drm: Check locking in drm_for_each_connector

I added locking checks to drm_for_each_connector but failed that
through drm_helper_connector_dpms -> drm_helper_choose_encoder_dpms
it's used in a few more places in the amdgpu resume/suspend code.

Fix them up.

Note that we could use the connector iterator macros in there too, but
that's for the future.

monk.liu 5c3422b0b1 drm/amdgpu: sync ce and me with SWITCH_BUFFER(2)
we used to adopt wait_reg_mem to let CE wait before DE finish page
updating, but from Tonga+, CE doesn't support wait_reg_mem package so
this logic no longer works.

so here is another approach to do same thing:
Insert two of SWITCH_BUFFER at both front and end of vm_flush can
guarantee that CE not go further to process IB_const before vm_flush
done.

Insert two of SWITCH_BUFFER also works on CI, so remove legency method
to sync CE and ME

v2:
Insert double SWITCH_BUFFER at front of vm flush as well.

Dan Carpenter 1d263474c4 drm/amdgpu: unwind properly in amdgpu_cs_parser_init()
The amdgpu_cs_parser_init() function doesn't clean up after itself but
instead the caller uses a free everything function amdgpu_cs_parser_fini()
on failure.  This style of error handling is often buggy.  In this
example, we call "drm_free_large(parser->chunks[i].kdata);" when it is
an unintialized pointer or when "parser->chunks" is NULL.

I fixed this bug by adding unwind code so that it frees everything that
it allocates.

I also mode some other very minor changes:
1) Renamed "r" to "ret".
2) Moved the chunk_array allocation to the start of the function.
3) Removed some initializers which are no longer needed.
