Linux/DRA716: Could you please give us some 3D SRV boot up time optimize suggest?

Part Number: DRA716
Other Parts Discussed in Thread: TDA2E

Tool/software: Linux

Hi Expert:

Now we enter 3D SRV need ~10s. It need too long time.

Please give us some suggest about how to optimize it?

Best Regards!

Han Tao

Those four item need too long time.

Kernel boot time optimize are follow Linux APN now. (http://www.ti.com/lit/an/sprac82/sprac82.pdf)

Hardware: TDA2E 17*17 800MHz,   MLO+uboot+kernel+filesystem store at QSPI

Software: VisionSDK 2.12.02

    Here are some optimization you could try.

    1. Parallelize SGX-init with Blend-LUT creation – The SGX link initialization is the long poll in the 3D-SRV use-case, we can parallelize the blend lut creation when the SGX link is being initialized. This saves ~1s in start-up up time 
    2. Bypass Geometric alignment link – The geometric alignment link of the DSP takes ~4s to compute the geometric alignment LUT. This can be bypassed if a CALMAT / Calibtable is being used (specifically disable the call to SV_GalignRun).
