Lang Yu a5a400c958 tests/amdgpu: fix bo eviction test issue 
On Raven2/Picasso, the default VRAM size is 2048M,
and the default GTT size is 3072M. If max_allocation
of VRAM exceeds half of GTT size, GTT memory can't
hold evicted bo from VRAM and bo in itself at the
same time. Then amdgpu_cs_list_validate will failed
with "Not enough memory for command submission" error.

NOTE:
The installed DRAM should be larger than 8GB,
if the VRAM size is 2048M.

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.
