Problem importing buffer allocated by etnaviv to imx-drm

[Martin Fuzzey]

Hi,

I'm trying to run etnaviv on i.MX6 / Android.

Using kernel 4.14 and mesa 17.3-rc2 with the latest drm_hwcomposer and 
gbm_gralloc

The problem I have is that when HWC tries to import the first client 
buffers (from bootanimation) there are errors like:

01-01 17:27:02.282   443   443 E hwc-platform-drm-generic: failed to 
import prime fd 25 ret=-1

This is because the imx-drm kernel driver wants physically contiguous 
buffers for import (it uses drm_gem_cma_prime_import_sg_table()) but the 
buffer allocated by drm etnaviv isn't contiguous...

Any ideas on this?


Regards,

Martin
