      drm: add missing drm_mode_set_crtcinfo call · b201e743
      由 Tomi Valkeinen 提交于 
      When setting mode via MODE_ID property,
drm_atomic_set_mode_prop_for_crtc() does not call
drm_mode_set_crtcinfo() which possibly causes:

"[drm:drm_calc_timestamping_constants [drm]] *ERROR* crtc 32: Can't
calculate constants, dotclock = 0!"

Whether the error is seen depends on the previous data in state->mode,
as state->mode is not cleared when setting new mode.

This patch adds drm_mode_set_crtcinfo() call to
drm_mode_convert_umode(), which is called in both legacy and atomic
paths. This should be fine as there's no reason to call
drm_mode_convert_umode() without also setting the crtc related fields.

drm_mode_set_crtcinfo() is removed from the legacy drm_mode_setcrtc() as
that is no longer needed.

      drm: Switch blobs to the new generic modeset obj refcounting · 152ef5fa
      由 Daniel Vetter 提交于 
      Need to move the free function around a bit, but otherwise mostly
just removing code.

Specifically we can nuke all the _locked variants since the weak idr
reference is now protected by the idr_mutex, which we never hold
anywhere expect in the lookup/reg/unreg functions. And those never
call anything else.

Another benefit of this is that this patch switches the weak reference
logic from kref_put_mutex to kref_get_unless_zero. And the later is in
general more flexible wrt accomodating multiple weak references
protected by different locks, which might or might not come handy
eventually.

But one consequence of that switch is that we need to acquire the
blob_lock from the free function for the list_del calls. That's a bit
tricky to pull off, but works well if we pick the exact same scheme as
is already used for framebuffers. Most important changes:

- filp list is maintainer by create/destroy_blob ioctls directly
  (already the case, so we can just remove the redundant list_del from
  the free function).

- filp close handler walks the filp-private list lockless - works
  because we know no one else can access it. I copied the same comment
  from the fb code over to explain this.

- Otherwise we need to sufficiently restrict blob_lock critical
  sections to avoid all the unreference calls. Easy to do once the
  blob_lock only protects the list, and no longer the weak reference.

      drm: Fix fb leaks and WARN spew in get/set_prop ioctls · 1649c33b
      由 Daniel Vetter 提交于 
      Dave Airlie had at least the refcount leak fixed in a later patch (but
that patch does other things which need a bit more work). But we still
have the trouble that silly userspace could hit the WARN_ON in
drm_mode_object_find.

Fix this all up to make sure we don't leak objects, and don't spew
into demsg.

      drm: Improve kerneldoc for new mode object refcounting · 05981422
      由 Daniel Vetter 提交于 
      Slipped through the cracks in my review. The one issue I spotted
is that drm_mode_object_find now acquires references and can be
used on FB objects, which caused follow-on bugs in get/set_prop ioctls.
Follow-up patches will fix that.

      drm: Add an encoder and connector type enum for DPI. · 0b27c02a
      由 Eric Anholt 提交于 
      Right now exynos is exposing DPI as a TMDS encoder and VGA connector,
which seems rather misleading.  This isn't just an internal detail,
since xrandr actually exposes "VGA" as the output name.  Define some
new enums so that vc4's DPI can have a more informative name.

I considered other names for the connector as well.  For VC4, the
Adafruit DPI kippah takes the 28 GPIO pins and routes them to a
standard-ish 40-pin FPC connector, but "40-pin FPC" doesn't uniquely
identify an ordering of pins (apparently some other orderings exist),
doesn't explain things as well for the user (who, if anything, knows
their product is a DPI kippah/panel combo), and actually doesn't have
to exist (one could connect the 28 GPIOs directly to something else).
Simply "DPI" seems like a good compromise name to distinguish from the
HDMI, DSI, and TV connectors .

      drm/atomic: Allow for holes in connector state, v2. · 5fff80bb
      由 Maarten Lankhorst 提交于 
      Because we record connector_mask using 1 << drm_connector_index now
the connector_mask should stay the same even when other connectors
are removed. This was not the case with MST, in that case when removing
a connector all other connectors may change their index.

This is fixed by waiting until the first get_connector_state to allocate
connector_state, and force reallocation when state is too small.

As a side effect connector arrays no longer have to be preallocated,
and can be allocated on first use which means a less allocations in
the page flip only path.

Changes since v1:
- Whitespace. (Ville)
- Call ida_remove when destroying the connector. (Ville)
- u32 alloc -> int. (Ville)
