TDA4VH-Q1: wave5 decoding

Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: TDA4VH

Hi Ti:

We use the tda4vh 8.6 sdk, and found that in the linux sdk 9.0 driver, the wave5 driver has a submission about memory optimization, the link is as follows

git.ti.com/.../wave5

We updated the submitted patch. After the update, we found that the use of cma memory is indeed optimized when decoding. The problem is that we can decode the h264 video of 3840X1080 normally, but when we switch to the h264 video of 1920*1080, the decoding will be stuck. , there is no abnormal print, and the whole system is stuck and can only be powered off and restarted

Regards，

Hi Gary,

Could you share with me the patch you applied? I see that you mention it is an updated version of the patch we carry in our Kernel. Please also share what Kernel version you applied the patch on top of. Was it the 5.10 Kernel? Please share commit as well so I can make sure my set up can replicate the issue you are currently seeing.

Best,

Brandon
