Do Linux Arm version support 64bit GUI?

[cyguan]

Hi,

I've installed LinuxArm version and can have bit_cmd_line_aarch64 activate my key and run in command line mode on my platform.
But I would like to run the graphic 2D/3D tests as well. However, the gui seems to support 32-bit arm only.
Is there any way I can make GUI run on my arm64 linux(Debian base Ubuntu 20.04)? If not now, any plan to support it?

We support 64bit on all platforms (to be honest that's 99% of the market nowadays).

What was the error you are getting and what hardware are you using?

Hi David,

Thanks for the prompting response. The hardware is an embedded Qualcomm QCS6490 dev kit. I'm running it on a Yocto Ubuntu 20.04 baked by Qualcomm.
To clarify, I have no problem run it in 64-bit. But only in CMDLINE mode, but graphical one. And from the manual P13, it suggests command line mode cannot run 2D/3D tests. So I'd like to find a way to launch GUI one. (The gui itself doesn't matter that much, the point is the ability to test graphics)

"The command line version of BurnInTest does not have a Graphical User Interface and as such does not require any graphical libraries to be installed but require ncurses to display information. This also means it is missing some of the tests from the GUI version, the 2D and 3D tests"

Here is everything I got in BurnInTest_Linux_ARM.tar.gz.

I'll expect bit_gui_arm to be the graphical version.
But it's a 32bit binary from file command:

--
sh-5.0# file bit_gui_arm
bit_gui_arm: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, BuildID[sha1]=795f996af0dea3ef635bff6278ef60d08e1ed6b4, for GNU/Linux 3.2.0, stripped

Am I missing anything?
Thanks

Sorry it's at manual Section 13 P64 not P13.

It was the case that all 64bit machines would also run 32bit binaries. So it was no problem having a mix of 64bit and 32bit binaries on a 64bit machine. (64bit was only ever really required for tasks that needed more than 4GB of RAM, and a simple GUI didn't need this).

I am guessing that your Ubuntu version has stopped including 32bit libraries. So breaking backwards compatibility with 32bit applications.

It might be possible to install the 32bit libraries.
Running a slightly older version of Ubuntu might also help.

But I just did a bit more checking:
bit_gui_arm built with a Yocto linux toolchain using Qt 5.15, will only work on limited systems based on this toolchain. Due to some 64-bit libraries used in the GUI not being available or incompatible, we are not able generate the GUI for 64-bit arch on ARM. So at the time we built this, Qt (the graphics API we use on Linux) was broken on 64bit ARM Yocto, and we couldn't get it working. As you are probably aware, Linux has never ending compatibility issues. This was a few years ago however. Things might have improved now, we should probably have another look at it.
