[media] CODA960: Fails to allocate memory
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 204.vpu: Firmware code revision: 46056
[4.416312] coda 204.vpu: Initialized CODA960.

[4.483577] coda 204.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

I assume this is physically contiguous memory. Do you have that much phys.
cont. memory
available at all? If the memory is fragmented you won't be able to get it.
Use cma (contiguous memory allocator). You probably have to do very little
expect add
a kernel option to assign enough memory for these buffers.

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

Mmmh, nice, didn't thought to get perf out of there :). Well, I understand it can't feed the ringbuffer, but is there a way to make the encoder work ? I could of course modify CODA_MAX_FRAME_SIZE but this is clearly not the good thing to do...
