19:38 <dougg3> i believe i figured out the pxa168/gc300 issue i mentioned earlier. problem #1: the vivante driver is missing a special check for old versions of the gc300 that have the power registers offset by 0x100

19:38 <dougg3> https://github.com/etnaviv/vivante_kernel_drivers/blob/master/imx8_v6.2.3.129602/hal/kernel/arch/gc_hal_kernel_hardware.c#L1152

19:39 <dougg3> s/vivante/etnaviv/, sorry

19:40 <dougg3> and then problem #2 is that i think the gc300 is affected by the same issue in the gc600 where certain idle register bits are set where modules aren't present

19:41 <dougg3> with both of those issues patched, i don't get any errors in the module load anymore. but honestly, i have no idea how to test it after that! etnaviv_2d_test doesn't seem to work...
