Aman, All,
Thanks fior this patch. However, I have some comments about it, see
below...
On 2020-10-16 18:13 -0700, Aman Karmani spake thusly:
> Parts of the userland (such as `vcgencmd`) are now usable on aarch64
This has already been proposed a few times already (review all the
messages in those threads):
http://lists.busybox.net/pipermail/buildroot/2020-August/289559.html
http://lists.busybox.net/pipermail/buildroot/2020-January/271577.html
There, it was pointed out that the set of libraries instaleld on AArch64
is different from AArch32, and most notably "no libegl, libgles,
libopenmax, libopenvg" are built and installed.
This means that rpi-userland couldn't be an EGL or GLES or OPENMAX
provider when building for AArch64.
Has that situation improved now?
Regards,
Yann E. MORIN.
