VPU Encoding fails intermittently

saurabh206 · ‎03-23-2014

Hi,

I am using custom hardware based in IMX6q and jb4.3_1.1.0 is ported on it.

I am getting media server crash and restarted my system while 1280x720 H264 encoding.

Please find the attached log.

Any resolution on this one?

I'm having the same crash on SurfaceFlinger.

Hi,

What is a FBMem in your bootargs?

Increase the FBMem size in bootargs.

Regards

Saurabh

iditlevycarmel · ‎07-26-2014

Hi,

We're using 'fbmem=14M,28M' for two FBs

What the values should be? Are you familiar with the calculation?

Thanks for your quick response!

Idit

saurabh206 · ‎07-27-2014

Hi,

Idit

Try to set 32M for both.

Regards,

Saurabh

dangluskin · ‎07-28-2014

As far as I recall, fbmem should be <x-resolution>*<y-resolution>*<bytes per pixel>*<number-of-buffers>

where:

<bytes-per-pixel> is 4 for us (32bpp) and <number-of-buffers> is 3.

Hence, we should use:

for the main display: 1280x800x4x3=12.28M => 13

and for the external display: 1920x1200x4x3 = 27.6 => 28

what am I missing?

saurabh206 · ‎07-28-2014

Hi,

Your calculation is correct please increase the buffer to 4 and check,

Hello Saurabh,

We have seen this crash once again in screencap:

Checking with Idit, it appears that we didn't increase the fbmem size.

The values that we currently use are: fbmem=14M,28M

Shall it be: fbmem=32M,32M ? Or only increase one of them?

Could you please explain how did you get to this number?

Thank you

Yaakov

saurabh206 · ‎09-16-2014

Hi,

Yaakov

What is your display resolution?

fbmem should be <x-resolution>*<y-resolution>*<bytes per pixel>*<number-of-buffers>.

Regards

Saurabh

yaakovsimony · ‎09-16-2014

Hi Saurabh,

We are using resolution 1920x1080, 32bits per pixel and allocating 3 buffers.

So, according to the formula above, we need 1920x1080x4x3 = 24300KB.

We currently allocate 28MB, which should be sufficient.

Regarding LVDS, its resolution is 1280x800, i.e. 12000KB.

We allocated 14MB. This also should be sufficient.

So, why should we increase fbmem values?

Thanks

Yaakov

yaakovsimony · ‎09-22-2014

Hi Saurabh,

Did you have a chance to look at my last question?

Any hint?

Thanks

Yaakov

saurabh206 · ‎09-22-2014

Hi

Yaakov

I could not able to debug very deeply but after increasing the frame buffer I haven't seen any more crash in VPU encoding.

Share your result after increasing the frame buffer to 4.

Any Valuable comment from Freescale Team on this issue.

Regards

Saurabh

Hi,

I could not able to check.

yaakovsimony · ‎09-23-2014

Hi Saurabh,

In our code, fbmem value is set to: fbmem=14M,28M.

I looked in the code who is parsing this string and I find that it is routine fixup_mxc_board(), in file arch/arm/mach-mx6/board-mx6q_sabresd.c.

I found this comment there:

/* SUMMIT-1640

* The first allocation pool (pdata_fb[i].res_size[0]) is used by the SurfaceRenderer for allocating buffers.

* The SurfaceRenderer is using RGBA pixel format. In summit we use 32bit per pixel (4 Bytes).

* The SurfaceFlinger use the pool to allocate 3 buffers.

* And hence, the pool size should be <width> x <height> x <bits-per-pixel> x 3, where

* <width> ::= monitor width in pixels (e.g. 1920)

* <height> ::= Monitor height in pixels (e.g. 1080)

* The second allocation pool (pdata_fb[i].res_siize[1]) is used by the ipuRenderer for allocating buffers for the IPU-IC sc

* The ipuRenderer configures the IPU-IC to scale the NV12 video from the decoder to a 16 bits-per

* pixel YUYV buffer.Hence, the second allocation size *** can be half of *** the first allocation

* (the first is the number specified in boot-args */

According to it, our calculation may be right, but the fbmem value is set in the wrong order.

It should be: fbmem=28M,14M, so the second allocation size is half of the first one.

Could it be the reason why we see these VPU Encoding failures?

Because we need 28M in the first pool and we give only 14M?

Thanks

Yaakov
