[Buildroot] [PATCH v2 2/7] package/freescale-imx/imx-dpu-g2d: new package imx-dpu-g2d package is used by i.MX 8 and i.MX 8X series instead of imx-vpu or imx-vpu-hantro.With this commit, imx-dpu-g2d is added and is enabled for i.MX 8X.

Hello Refik,

I was about to apply after fixing a few things, but there is one issue
that I can't really resolve by myself without asking some questions. So
while at it, I'll do the various comments.

First, the commit log is not good, you should have an empty line after
the commit title (package/freescale-imx/imx-dpu-g2d: new package),
otherwise everything goes into the commit title.

So this is the problem. What makes you think this needs imx-gpu-viv ?
When I run readelf -d on the only library installed by this package, I
see this:

$ readelf -d libg2d-dpu.so 

Dynamic section at offset 0xadc8 contains 26 entries:
  Tag        Type                         Name/Value
 0x0000000000000001 (NEEDED)             Shared library: [libdrm.so.2]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]
 0x000000000000000e (SONAME)             Library soname: [libg2d.so.1.1]

So it means that it needs libc.so.6 (so we need glibc) and libdrm.so.2.
And libdrm.so.2 is not installed by imx-gpu-viv. So it seems like it
doesn't need imx-gpu-viv, but instead another package that provides
libdrm.so.2 (probably libdrm, but please check).

So that would have to be changed.

We normally use

	cp -dpfr

instead of cp -a.

Please use:

	cp -dpfr $(@D)/g2d/usr/lib/* $(TARGET_DIR)/usr/lib/

instead.

Could you fix the above issues, and resend ? The
imx-gpu-viv/libdrm.so.2 issue is the most important one.

Thanks a lot!
