Add a wrapper around the getfb2 ioctl, which returns extended framebuffer information mirroring addfb2, including multiple planes and modifiers. Changes since v7: - add new symbols to core-symbol.txt (Eric Engestrom) Changes since v5: - style change Changes since v4: - Set fb_id at init instead of memclear() and set (Eric Engestrom) Changes since v3: - remove unnecessary null check in drmModeFreeFB2 (Daniel Stone) Changes since v2: - getfb2 ioctl has been merged upstream - sync include/drm/drm.h in a seperate patch Changes since v1: - functions should be drm_public - modifier should be 64 bits - update ioctl number Signed-off-by: Juston Li <juston.li@intel.com> Signed-off-by: Daniel Stone <daniels@collabora.com> Reviewed-by: Eric Engestrom <eric@engestrom.ch> |

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.
New functionality in the kernel DRM drivers typically requires a new libdrm,
but a new libdrm will always work with an older kernel.
libdrm is a low-level library, typically used by graphics drivers such as
the Mesa drivers, the X drivers, libva and similar projects.
Compiling
---------
To set up meson:
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.
