For me the link isn’t dead. Here’s the URL behind the link:
You seem to have found the same thread from one of the mailinglist aggregating sites.
- What is the “userspace Vivante component”?
e.g. the X11 driver , libGLES.so etc.
- Where is it defined?
Depending on the BSP version you are using there might be additional bbappend files messing with the versions used.
- How to know if he kernel driver matches the Version of the userspace component?
You would check in NXP’s original BSP what kernel version (meaning the exact downstream version) they use with what version of the userspace components.
Alternatively you could check ‘drivers/mxc/gpu-viv/hal/kernel/inc/gc_hal_version.h’ in your kernel and compare that with the userspace recipe versions.
