VPI support

[hannes09]

Hi,

is support of VPI already scheduled for a future release?

I tried to set it up myself with the following recipe:

SUMMARY = "NVIDIA Vision Programming Interface"
LICENSE = "CLOSED"

inherit bin_package

HOMEPAGE = "https://developer.nvidia.com/embedded/vpi"

DEPENDS = "cuda-cudart"

COMPATIBLE_MACHINE = "(tegra)"

SRC_URI = "${NVIDIA_DEVNET_MIRROR}/vpi-lib-${PV}-aarch64-l4t.deb "

S = "${WORKDIR}"

INHIBIT_PACKAGE_STRIP = "1"
INHIBIT_PACKAGE_DEBUG_SPLIT = "1"
INHIBIT_SYSROOT_STRIP = "1"

do_package_qa[noexec] = "1"
EXCLUDE_FROM_SHLIBS = "1"

But the build fails with

 conflicting requests
  - nothing provides ld-linux-x86-64.so.2()(64bit) needed by vpi-1.0.15-r0.armv8a
  - nothing provides ld-linux-x86-64.so.2(GLIBC_2.3)(64bit) needed by vpi-1.0.15-r0.armv8a

Hey @hannes09
I'm working on it with @madisongh.
Hopefully we will provide it soon.

I will let you know

Hey @hannes09

The VPI support is available in meta-tegra (master and dunfell-l4t-r32.5.0 branch).

• dunfell-l4t-r32.5.0 branch VPI
• master branch VPI

You can use tegra-demo-distro to try the VPI sample applications as well.

$ git clone https://github.com/OE4T/tegra-demo-distro.git
$ cd tegra-demo-distro
$ git submodule update --init --recursive

Please let me know if you need help.
