Hi,
I needed some help with respect to binding of freedreno driver to mesa
I have cross compiled freedreno driver for A2XX with main line kernel
and added clocking info referring driver from TQ-Embedded
"https://www.tq-group.com/en/support/download
/?tx_abdownloads_pi1%5Baction%5D=getviewcategory&tx_abdownloads_pi1%5Bcategory_uid%5D=672&tx_abdownloads_pi1%5Bcid%5D=84&tx_abdownloads_pi1%5Bpointer%5D=1&cHash=5e7c087ae16a9426fc0353db0042615a"
I also cross-compiled, libdrm and mesa components from freedreno git hub
But when I am running "glxinfo" command to verify whether underlaying 3D
acceleration is being used, I am observing that softpipe is being used
instead of "freedreno"
I figured it out that glxinfo uses mesa/src/mesa/drivers/dri/swrast as
user side driver component
Files under /src/mesa/drivers/dri use "_mesa_initialize_context" to
register them self to mesa component. But I am not seeing any freedreno
related source files calling "_mesa_initialize_context"
Can you please let me know whether I have to add mesa related
functionalities for freedreno or there some other alternatives?
Thank you very much :)

Hi,
We are working on iMx53 Quick start board based on iMx53 application
processor. As you know this has A200 GPU.
If I see in the mainline kernel 4.11.3, there are no source files for
A2XX GPU. Based on this I am assuming that the mainline doesn't have
support for A2XX.
However in kernel-msm git checkout from Freedreno, there are A2XX
related source code. I wanted to know whether this code is tested one
and reason for non-inclusion of this code in mainline kernel.
Are there any pointers how I can go about it.
Thank you very much :)

Abhijit
