Linux/AM5728: dmatest not working

TDA4VM Linux : dmatest not working

Hi expert:

We use TDA4 Linux SDK 0802.

we test dmatest according to  /Documentation/driver-api/dmaengine/dmatest.rst, but there are some errors when  request channels.

We add some debug log in dmatest.c as follows.

    Hi Zhao,

    Can you share the complete logs as a text file attachment please? Also is the intent just to test dma or enable a new dma channel for a peripheral?

    kern.log

    We want to use DMA_MEMCPY.

    Hi,

    The log states that you are requesting channels that are already in use. Take a look at /sys/kernel/debug/dma and see which are already in use and request something that's not already in use.

    Best Regards,

    Keerthy

    Hi,

    I use dma1chan7 can set, but it seems that there are no more channels available when request channel fot type DMA_MEMCPY.

    Hi,

    There are limited channels allocated. So if this is for testing purposes can you please disable the cpsw node that takes up some channels.

    Ex : Add node disabling like below in: arch/arm64/boot/dts/ti/k3-j721e-common-proc-board.dts

    &cpsw0 {
            status = "disabled";
    };

    or

    &main_crypto {
            status = "disabled";
    };

    This should free up some channels.
