In trying to integrate the new gralloc_handle.h with the
drm_hwcomposer, I started seeing the following compilation
errors:
In file included from external/drm_hwcomposer/platformdrmgeneric.cpp:28:
external/libdrm/android/gralloc_handle.h:108:9: error: cannot initialize return object of type 'native_handle_t *' (aka 'native_handle *') with an lvalue of type 'struct gralloc_handle_t *'
return handle;
^~~~~~
1 error generated.
This seems to be due to the gralloc_handle_create() definition
needs to return a native_handle_t * type, rather then a
gralloc_handle_t *, which is what the code actually returns.
After talking w/ Rob Herring, having the code return the
native handle should be the proper fix, so that is what
this patch changes.

libdrm - userspace library for drm
This is libdrm, a userspace library for accessing the DRM, direct
rendering manager, on Linux, BSD and other operating systems that
support the ioctl interface. The library provides wrapper functions
for the ioctls to avoid exposing the kernel interface directly, and
for chipsets with drm memory manager, support for tracking relocations
and buffers. libdrm is a low-level library, typically used by
graphics drivers such as the Mesa DRI drivers, the X drivers, libva
and similar projects. New functionality in the kernel DRM drivers
typically requires a new libdrm, but a new libdrm will always work
with an older kernel.
Compiling
---------
libdrm has two build systems, a legacy autotools build system, and a newer
meson build system. The meson build system is much faster, and offers a
slightly different interface, but otherwise provides an equivalent feature set.
To use it:
meson builddir/
By default this will install into /usr/local, you can change your prefix
with --prefix=/usr (or `meson configure builddir/ -Dprefix=/usr` after
the initial meson setup).
Then use ninja to build and install:
ninja -C builddir/ install
If you are installing into a system location you will need to run install
separately, and as root.
Alternatively you can invoke autotools configure:
./configure
By default, libdrm will install into the /usr/local/ prefix. If you
want to install this DRM to replace your system copy, pass
--prefix=/usr and --exec-prefix=/ to configure. If you are building
libdrm from a git checkout, you first need to run the autogen.sh
script. You can pass any options to autogen.sh that you would other
wise pass to configure, or you can just re-run configure with the
options you need once autogen.sh finishes.
Next step is to build libdrm:
make
and once make finishes successfully, install the package using
make install
If you are installing into a system location, you will need to be root
to perform the install step.
