6 This document describes how to do DMA transfers using the old ISA DMA
7 controller. Even though ISA is more or less dead today the LPC bus
13 To do ISA style DMA you need to include two headers:
21 The second contains the routines specific to ISA DMA transfers. Since
23 Kconfig to be dependent on ISA_DMA_API (not ISA) so that nobody tries
29 The ISA DMA controller has some very strict requirements on which
43 Unfortunately the memory available for ISA DMA is scarce so unless you
56 will require a Kconfig dependency to ISA, not just ISA_DMA_API which
58 has its origins in ISA it is used elsewhere.
60 Note: x86_64 had a broken DMA API when it came to ISA but has since
62 reverting to the ISA functions.
67 A normal ISA DMA controller has 8 channels. The lower four are for
88 Before you use any ISA DMA routines you need to claim the DMA lock
