Re: [PATCH v2 0/13] Patches to improve transfer efficiency for Rockchip SoCs.

[Peter Geis]

Good Evening,

I am currently testing this on the rk3399-rockpro64, and it appears to
fully fix the gmac problem without using txpbl.
PCIe also seems to be more stable at high load.
I need to conduct long term testing, but it seems to be doing very well.

Unfortunately it doesn't fix the rk3328 gmac controller.

Belay that, it does make it harder to trigger, but the issue still
remains on the rk3399.

Re: [PATCH v2 0/13] Patches to improve transfer efficiency for Rockchip SoCs.

[sugar zhang]

dma(pl330) for data transfer,

so, these patchs should not be helpful for your case.
