I assume this was implemented in a previous version of that commit, but
was removed in the version that actually landed.

Adding gbm_device_get_format_modifier_plane_count made the
test gbm-symbols-check fail, this patch adds the according
function name to the test.

This patch originally had i965 specific code and was named:
commit 61cd3c52b868cf8cb90b06e53a382a921eb42754
Author: Ben Widawsky <[email protected]>

gbm: Get modifiers from DRI
To accomplish this, two new query tokens are added to the extension:
__DRI_IMAGE_ATTRIB_MODIFIER_UPPER
__DRI_IMAGE_ATTRIB_MODIFIER_LOWER
The query extension only supported 32b queries, and modifiers are 64b,
so we needed two of them.
NOTE: The extension version is still set to 13, so none of this will
actually be called.
v2: Error handling of queryImage (Emil)

The idea behind modifiers like this is that the user of GBM will have
some mechanism to query what properties the hardware supports for its BO
or surface. This information is directly passed in (and stored) so that
the DRI implementation can create an image with the appropriate
attributes.
A getter() will be added later so that the user GBM will be able to
query what modifier should be used.
Only in surface creation, the modifiers are stored until the BO is
actually allocated. In regular buffer allocation, the correct modifier
can (will be, in future patches be chosen at creation time.
v2: Make sure to check if count is non-zero in addition to testing if
calloc fails. (Daniel)
v3: Remove "usage" and "flags" from modifier creation. Requested by
Kristian.
v4: Take advantage of the "INVALID" modifier added by the GET_PLANE2
series.
v5: Don't bother with storing modifiers for gbm_bo_create because that's
a synchronous operation and we can actually select the correct modifier
at create time (done in a later patch) (Jason)
v6: Make modifier condition outside the check so that dri_use will work
properly (Jason)

Unlike stride, there was no previous offset getter, so it can be right
on the first try.
v2: Return EINVAL when plane is greater than total planes to make it
match the similar APIs.
Avoid leak after fromPlanar (Daniel)
Make sure when getting offsets we consider dumb images (Daniel)
v3: Use Jason's recommendation for handling the non-planar case.
v4: Return int64_t so we can get real errors
v5: Add an assertion for dumb BOs (Jason)

v2: Preserve legacy behavior when plane is 0 (Jason Ekstrand)
EINVAL when input plane is greater than total planes (Jason Ekstrand)
Don't leak the image after fromPlanar (Daniel)
Move bo->image check below plane count preventing bad index succeeding (Daniel)
v3: Fix DRIimage leak (using Jason's recommended change)
Make plane 0 return planar stride. This might break legacy behavior (Jason)
v4: Move bogus hunk for get_handle_for_plane to the right patch (Jason)
Fix error handling path to be cleaner (Jason)
v5: Add assert for dumb BOs to make sure plane == 0 (Jason)

v2: Make the error return be -1 instead of 0 because I think 0 is
actually valid.
v3: Set errno to EINVAL when the specified plane is above the total
planes. (Jason Ekstrand)
Return the bo's handle if there is no image ie. for dumb images like cursor (Daniel)
v4:
- Add assertions about plane == 0 (Jason)
- Add a comment about new restriction on planar dumb bo which is not an
earlier patch in the series.
- Correctly refactor from v2 in this patch; it ended up rebased into the
wrong patch.

This will be used by clients that need to know the number of planes
allocated for them on behalf of the GL or other API. The best current
example of this is when an extra "plane" is allocated to store
compression data for the primary plane.
v2: Return 1 for cases where there is no image, ie. dumb bo (Daniel)

This adds map and unmap functions to GBM utilizing the DRIimage extension
mapImage/unmapImage functions or existing internal mapping for dumb
buffers. Unlike prior attempts, this version provides a region to map and
usage flags for the mapping. The operation follows the same semantics as
the gallium transfer_map() function.
This was tested with GBM based gralloc on Android.

Turn GBM into a swrast loader (providing putimage/getimage backed
by a dumb KMS buffer). This allows to run KMS+DRM GL applications
(such as weston or mutter-wayland) unmodified on cards that don't
have any client side HW acceleration component but that can do
modeset (examples include simpledrm and qxl)
[Emil Velikov]
- Fix make check.
- Split dri_open_driver() from dri_load_driver().
- Don't try to bind the swrast extensions when using dri.
- Handle swrast->CreateNewScreen() failure.
- strdup the driver_name, as it's free'd at destruction.
- s/LIBGL_ALWAYS_SOFTWARE/GBM_ALWAYS_SOFTWARE/
- Move gbm_dri_bo_map/unmap to gbm_driiint.h.
- Correct swrast fallback logic.
