548a3d5fd6 modesetting: create entities for pci and old probe. (v2)
This moves the code from the platform case into
a common function, and calls that from the
other two.

v2: Emil convinced me we don't need to lookup pEnt
here, so let's not bother.

139e36dd5c modesetting: fix up output naming convention
A user on a nouveau-driven card ran into a problem where DVI-D-1 and
DVI-I-1 were aliasing. The simplest fix is to provide the full connector
names. While we're at it, rename the output names to match what is in
the kernel, and start counting the connectors from 1 rather than 0. The
only deviation is HDMI vs HDMI-A, which kept its original name.

This will break backwards compatibility with existing xorg.conf's that
reference output names, but the alternative is to create a separate
counting system, further disconnecting from the kernel names.

90db5edf11 prime: add rotation support for offloaded outputs (v2)
One of the lacking features with output offloading was
that screen rotation didn't work at all.

This patch makes 0/90/180/270 rotation work with USB output
and GPU outputs.

When it allocates the shared pixmap it allocates it rotated,
and any updates to the shared pixmap are done using a composite
path that does the rotation. The slave GPU then doesn't need
to know about the rotation and just displays the pixmap.

v2:
rewrite the sync dirty helper to use the dst pixmap, and
avoid any strange hobbits and rotations.

This breaks ABI in two places.

13c7d53df8 modesetting: Implement page flipping support for Present.
Based on code by Keith Packard, Eric Anholt, and Jason Ekstrand.

v2:
- Fix double free and flip_count underrun (caught by Mario Kleiner).
- Don't leak flip_vblank_event on the error_out path (Mario).
- Use the updated ms_flush_drm_events API (Mario, Ken).

v3: Hack around DPMS shenanigans.  If all monitors are DPMS off, then
    there is no active framebuffer; attempting to pageflip will hit the
    error_undo paths, causing us to drmModeRmFB with no framebuffer,
    which confuses the kernel into doing full modesets and generally
    breaks things.  To avoid this, make ms_present_check_flip check that
    some CRTCs are enabled and DPMS on.  This is an ugly hack that would
    get better with atomic modesetting, or some core Present work.

v4:
- Don't do pageflipping if CRTCs are rotated (caught by Jason Ekstrand).
- Make pageflipping optional (Option "PageFlip" in xorg.conf.d), but
  enabled by default.

v5: Initialize num_crtcs_on to 0 (caught by Michel Dänzer).

f6853baeba modesetting: Improve the ms_flush_drm_events() API.
Previously, ms_flush_drm_events() returned a boolean value, and it was
very easy to interpret the meaning incorrectly.  Now, we return an
integer value.

The possible outcomes of this call are:
- poll() raised an error (formerly TRUE, now -1 - poll's return value)
- poll() said there are no events (formerly TRUE, now 0).
- drmHandleEvent() raised an error (formerly FALSE, now the negative
  value returned by drmHandleEvent).
- An event was successfully handled (formerly TRUE, now 1).

The nice part is that this allows you to distinguish errors (< 0),
nothing to do (= 0), and success (1).  We no longer conflate errors
with success.

v2: Change ms_present_queue_vblank to < 0 instead of <= 0, fixing an
    unintentional behavior change.  libdrm may return EBUSY if it's
    received EINTR for more than a second straight; just keep retrying
    in that case.  Suggested by Jasper St. Pierre.

4e12d7b6f4 modesetting: Update the cursor without hiding it
In the new KMS APIs, the legacy drmModeSetCursor ioctl actually waits
for a vblank after changing the cursor image before returning, meaning
that the X server, in attempting to hide the cursor before updating
its image, actually makes that hide *visible* for a full vblank.

It's unknown why the X server does this by default, but turn it off.

If we're with a legacy driver that doesn't support the modern
drmModeSetCursor by waiting for a vblank before returning, we're going
to get a tiny bit of tearing on the cursor plane. But between tearing
with a new cursor image and tearing with a blank cursor image, I'd
rather the former.

The only proper solution to this is an atomic ioctl that page flips
all planes, including the cursor plane, at vblank time and at the same
time.

 * Unifies the code that was in  drmmode_load_cursor_argb and
  drm_mode_show_cursor and moves it to a new drmmode_set_cursor

 * Add a new boolean, 'cursor_up', to the per-crtc
   private data to track whether the cursor should be displayed.

 * Call drmmode_set_cursor from drm_mode_show_cursor and, if
   the cursor should be displayed, from drm_mode_load_cursor_argb.

v2: Call drmModeSetCursor2 when loading a new cursor image if the
    cursor should be displayed.

7b784df51b modesetting: Use GBM for buffer allocations if Glamor supports it.
For performance, Glamor wants to render to tiled buffers, not linear
ones.  Using GBM allows us to pick the 3D driver's preferred tiling
modes.

v2: Declare drmmode->gbm as void * if !GLAMOR_HAS_GBM.
v3: Just use a forward declaration of struct gbm_device.

980535757d modesetting: Create a drmmode_bo wrapper; use it for front_bo.
This code is going to be extended to support GBM BOs soon.  This small
abstraction removes a lot of direct dumb_bo access, so we can add that
support in one place, rather than putting conditionals at every
pitch/handle/etc access.

c6388964b0 modesetting: Drop dumb_bo::map_count field and dead unmap code.
The drm kernel API for dumb BOs apparently doesn't include an unmap
ioctl, so we can't do much here.  It looks like this code was copied
from libkms, which was also unfinished.

We may as well delete the dead variable that simply gets incremented
and never read.

87cc0c0d31 modesetting: Move dumb_bo into its own source files.
Eventually, drmmode_display will be able to use GBM for handling
buffers, and won't need dumb_bo.  Keeping the display related logic
and buffer object abstraction in separate files seems a bit tidier.

This will need to change when we add GBM support; by pulling it into a
helper function, we should only have to edit one place.

b4324c6a23 modesetting: Move ModifyPixmapHeader calls out of if/else branches.
Both branches called ModifyPixmapHeader with essentially the same
parameters.  By using new_pixels in the shadowfb case, we can make
them completely the same, and move them out a level, for simplicity.
