Hi,
I am trying to use the CODA960 driver on a 3.18 kernel.
It seems pretty good when the module is probed (appart from the
unsupported firmware version) but when I try using the encoder, it
fails allocating dma buffers.
Here is the DT part I added :
&vpu {
compatible = "fsl,imx6q-vpu";
clocks = <&clks 168>, <&clks 140>, <&clks 142>;
clock-names = "per", "ahb", "ocram";
iramsize = <0x21000>;
iram = <&ocram>;
resets = <&src 1>;
status = "okay";
};
When booting, I see :
[ 4.410645] coda 2040000.vpu: Firmware code revision: 46056
[ 4.416312] coda 2040000.vpu: Initialized CODA960.
[ 4.421123] coda 2040000.vpu: Unsupported firmware version: 3.1.1
[ 4.483577] coda 2040000.vpu: codec registered as /dev/video[0-1]
I can start v4l2-ctl and it shows that the device seems to be ok :
v4l2-ctl --all -d /dev/video1

VIDIOC_REQBUFS: failed: Cannot allocate memory
Did I forget to do something ?
Thanks,
