Finding ACPI Device to Initiate Platform Device for Kernel DMA API

I am trying to perform a DMA operation on my Dell Inspiron 5500 laptop. I would like to transfer, say a Linux page worth (4K on my machine), of data from one physical memory location to another. My questions are as follows

1. How do I determine if I have DMA support for this? I have tried decompiling and parsing /sys/firmware/acpi/tables/DSDT but I am unsure which node maps or would map to a DMA. I am significantly more familiar with device tree blobs in embedded system and this ACPI format is foreign to me

2. If I am able to locate this node, how do I get the

   struct device *dev;

in a platform driver to hand off to

struct dma_chan *dma_request_chan(struct device *dev, const char *name);

per this guidehttps://www.kernel.org/doc/html/latest/driver-api/dmaengine/client.html

Update:

Here are links to information files about the system

lspci -nk -vv

grep -H 15 /sys/bus/acpi/devices/*/status

If this is insufficient, I can add dmesg, but it is long since my machine has been running for a long time and I have doing stuff.
