This page displays information about the DMA (Direct Memory Access) Channels. A DMA channel is a direct connection that allows devices to transfer data to and from memory without going through the processor. Typically, i386-architecture systems (PC's) have eight DMA channels (0-7).
The exact information displayed is system-dependent. On some systems, DMA Channel information cannot be displayed yet.
On Linux this information is read from /proc/dma,
which is only available if the /proc pseudo-filesystem is compiled into the kernel.
A list of all currently-registered (ISA bus) DMA channels that are in use is shown.
The user cannot modify settings on this page.
