Hi Wladimir,
Thank you very much for you response.
I am using the kernel which is provided by you and I was able to
successfully get the GPU driver on to imx53 based QSRB board.
I am using the same kernel for imx53 based tx53 board from karo, but I
am having issue with getting GPU ID
Interestingly imx53.dtsi is common for both imx53-tx53-x13x.dts and
imx53-qsrb.dts.
imx53.dtsi contains DTS entries for GPU and clocks.
I verified that clock values are same for both qsrb and tx53. Only thing
I have to verify is if GPU completely powered on. Can you please let me
know how to ensure this?
Regards,
Abhijit

Hi All,
One more observation is, for TX53, uboot is enabling L2 cache "Enabling
L2 Cache .." but for QSRB it is not showing such message.
Please let me know if this can make difference. Which I think is
unlikely :)
Thank you for your help

Abhijit

Hi Wladimir,
I am facing issues while getting freedreno driver to work on imx53

I have earlier verified that A200 driver works for imx53 based QSRB
board from Freescale. However for tx53 board, register read for
getting chip ID is returning zero.
Interestingly for both boards, dtsi is common, i.e imx53.dtsi.This
dtsi contains,
Clock information for CPU
GPU device tree node
Clock rates for both boards as below,
kgsl_clock:gpu_clk 200000000
kgsl_clock:garb_clk 400000000
Following are output of /dev/cpuinfo for both boards
QSRB(IMX):
processor : 0
model name : ARMv7 Processor rev 5 (v7l)
BogoMIPS : 66.66
Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpd32

Can you please guide me how I can debug this issue or you have faced
similar issues when you were developing the driver?
From output of cpuinfo, I see that only BogoMIPS is different for
both CPUs, can this be an issue?

Abhijit

mesa/freedreno supports gles as well as gl.. perhaps you built mesa

Hi All,
I have requirement to support OPENGL ES 2.0 in GPU hardware.
But freedreno supports OPENGL 1.4. To support OPEN GL ES 2.0, I am
planning to boot old linux kernel with binary only GPU driver and use
reverse engineering tools. As I don't see any other option.
But before I start, I wanted to confirm whether Open GL ES 2.0 based
application can run with Open GL ES 1.4?
My end goal is to use chromium browser on IMX537 based board.
Please let me know your inputs.

Hello abhijit,
Now I am trying to run some 2D application from freedreno. I saw
that these
applications use libC2D2.
I was able to get this library for UNIX, but I am not able to get
libstlport
for UNIX which is one of dependencies. I am concluding libC2D2 is
specific
to Andriod
You shouldn't need stlport for UNIX. As far as I remember it is a
stand-alone
implementation of the C++ standard library. Both clang and GCC have
their
own state-of-the-art C++ standard libraries readily available.
I am planning to use MonkVG and run tiger application that comes with
Khronos so that I can use 3D renderer for 2D.
I am falling back to OPEN GL ES 2.0, as OPENVG implementation is
discontinued in Mesa
I'm not sure what is the state of support for the 2D core, the
Z160, in
freedreno. I personally will likely not have time to look at that.
Using the 3D hardware makes sense, however. For example the
application I'm
working on is also mostly a 2D application, it is built with Qt
Quick, which
uses OpenGL ES 2 as rendering backend.

Wladimir
