The function is effectively a direct function call into
libwayland-server.so.
Thus GBM no longer depends on the wayland-drm static library, making the
build more straight forward. And the resulting binary is a bit smaller.
Note: we need to move struct wayland_drm_callbacks further up,
otherwise we'll get an error since the type is incomplete.

At the moment wayland-clients, such as the Vulkan drivers were
over-linking against libwayland-server.so.
That went unnoticed, since both client and server code uses the
wl*interface symbols, which are present in both libwayland-client.so and
libwayland-server.so.
I've looked at correcting that, although that's orthogonal to this fix.
Note: wayland-egl does _not_ depend on wayland-client, although it does
need wayland-egl.h. There's no distinct package that provides it (I have
a WIP on the topic) so current solution will do for now.

The actual offset returned is uint32_t, however int64_t was used as the

In case of an error getting the offset, the user will also be unable to
get the handle/FD, and thus have nothing to offset into. This means that
returning 0 as an error value is harmless, allowing us to change the

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)

At the moment if a gbm buffer is imported and the gbm buffer
has an old-style GBM_BO_FORMAT format, the import will crash,
since it's passed directly to DRI functions that expect
a fourcc format (as provided by the newer GBM_FORMAT
definitions)
This commit addresses the problem in two ways:
1) it prevents invalid formats from leading to a crash by
returning EINVAL if the image couldn't be created
2) it translates GBM_BO_FORMAT formats into the comparable
GBM_FORMAT formats.

The whole of GBM does not rely on even a single symbol from the GL
dispatch library, unsuprisingly. The only need for it comes from the
unresolved symbols in the DRI modules, which are now correctly handled
with Frank's commit.

Dri driver libs are not linked to pull in libglapi so gbm_create_device()
fails when it tries to dlopen them (unless the application is linked
with something that does pull in libglapi, like libGL).
Until dri drivers can be fixed properly, dlopen libglapi before trying
to dlopen them.

glibc 2.19 introduced _DEFUAULT_SOURCE as a replacement for _BSD_SOURCE,
and deprecates _BSD_SOURCE with an annoying warning. Defining both is
how you're supposed to transition so let's do that. It gets rid of the
warning and we can figure out when/if we can drop _BSD_SOURCE later.

The driver name is no longer const, it's always allocated dynamically
one way or another. Drop const from dri_screen_create_dri2
driver_name argument to avoid warning.

The DRM_IOCTL_MODE_CREATE_DUMB (and others) IOCTL isn't very rigorously
specified, which has the effect that some kernel drivers do not consider
the .pitch and .size fields of struct drm_mode_create_dumb outputs only.
Instead they will use these as lower bounds and overwrite them only if
the values that they compute are larger than what userspace provided.
This works if and only if userspace initializes the fields explicitly to
either 0 or some meaningful value. However, if userspace just leaves the
values uninitialized and the struct drm_mode_create_dumb is allocated on
the stack for example, the driver may try to overallocate buffers.
Fortunately most userspace does zero out the structure before passing it
to the IOCTL, but there are rare exceptions. Mesa is one of them. In an
attempt to rectify this situation, kernel drivers are being updated to
not use the .pitch and .size fields as inputs. However in order to fix
the issue with older kernels, make sure that Mesa always zeros out the
structure as well.
Future IOCTLs should be more rigorously defined so that structures can
be validated and IOCTLs rejected if output fields aren't set to zero.

We don't want to log every single error (such as all the ones where the file
wasn't even present in our list of search paths), but if you didn't find any
driver, then seeing at least one error is useful (since the common case as a
developer is a single DEFAULT_DRIVER_DIR or GBM_DRIVERS_PATH entry).

Add a new winsys and target that can be used with a dri2 state tracker
and loader instead of drisw. This allows to use gbm as a dri2/image
loader and avoid the extra copy from the backbuffer to the shadow
frontbuffer.
The new driver is called "kms_swrast", and is loaded by gbm as a
fallback, because it is only useful with the gbm platform (as no buffer
sharing is possible)
To force select the driver set the environment variable
GBM_ALWAYS_SOFTWARE
[Emil Velikov]
- Rebase on top of gallium megadriver.
- s/text/test/ in configure.ac (Spotted by Andreas Pokorny).
- Add scons support for winsys/sw/kms-dri and fix the build.
- Provide separate DriverAPI, due to different InitScreen hook.

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.
