yeppp - support for aarch64 (armv8-a 64 bit)

[Virendra Kumar Pathak]

Hi Yeppp Group,

I am trying to use yeppp on juno board (aarch64 - armv8-a 64 bit).

But I got below error:

source set-vars.sh 

Error: could not detect host architecture: unknown architecture name aarch64 for OS Linux

Please refer to Yeppp! developers for a fix to this problem

Is yeppp supports aarch64 arm architecture ? Is there any patch for it?

If the support is not present, please give some insight on porting effort required ? What are the key areas in the library where works need to done?

Thanks,

Virendra Kumar Pathak

Hi Kumar,

The current version of Yeppp! does not support ARM64. If you want to get Yeppp! minimally working, you'd need to implement detection of ARM64 ISA extensions and few other architecture-dependent functions. I estimate it to be a day of effort. You can simply try to compile Yeppp! for ARM64 and you will get preprocessor errors on the lines that need implementation for ARM64.
However, there is little sense of using Yeppp! without optimized kernels, and creating optimized kernels would take several months of effort as it also involves porting PeachPy, the assembler used by Yeppp!, to ARM64.

Regards,
Marat
