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?
