2 monthes ago, latest BSP(L.3.14.52) was released and some GPU bugs were fixed.

Please see "i.MX Linux® Release Notes".

  * GPU driver upgraded to Vivante v5.0.11p7.4.

  * There were 3 kinds of kernel panic bugs.


According to the NOTE** below, driver can be upgraded.

So I want to try upgrading GPU driver (galcore) with old BSP(L3.10.17).


Have ever someone tried to backport/applied those GPU patches to old BSP?



p113 of  " i.MX Linux® Reference Manual" Source Code Structure

Table below lists GPU driver kernel module source structure:



  Table 13-1. GPU Driver Files

Kconfig Kbuild configKernel configure file and makefile
hal/kernel/archHardware-specific driver code for GC2000, GC880, GC400T, and GC320
hal/kernel/archvgHardware-specific driver code for GC355
hal/kernelKernel mode HAL driver
hal/os/linux/kernelOS layer HAL driver



If you replace the whole content in this directory, the GPU

kernel driver can be upgraded.
