NVAVP kernel driver in TX1

Hi,

I would like to know if NVAVP driver is not existed on TX1 ?
Or if it is not necessary to enable this driver in kernel ?
(Default OS doesn’t enable CONFIG_TEGRA_NVAVP)

I tried to search the document and I only see:

•usr/lib/<ABI_directory>/tegra/
libnvavp.so

•User-space interface to the AVP for
audio/video acceleration via the nvavp
kernel driver.

Could you please tell where the nvavp kernel driver is ?

Thanks.

Hi Tonie, this HW is not open for public.

Hi, DaneLLL,

I don’t understand. Could you please explain it more detail ?
Do you mean AVP doesn’t be supported on TX1 ?
Or other???

Please help to advise.

Tonie

Hi Tonie, it is a HW in TK1, not in TX1/TX2.

DaneLLL,

So you mean TX1 does not need to have AVP driver ???

Hi Tonie,
No, we don’t need it after booting to kernel.

Hi, DaneLLL,

We would like to let Chromium to access it.
I read user guide and it said :
•usr/lib/<ABI_directory>/tegra/
libnvavp.so
•User-space interface to the AVP for
audio/video acceleration via the nvavp
kernel driver.
Can this be used by Chromium?
Is there any API spec. for this ?

Please advise

No, it is not supported.

Hi, DaneLLL,
My customer would like to have Chromium to access it.
I believe they want to have ‘hw acceleration’ in Chromium.
Is there any alternate solution for this requirement ?

Please advise.
