Add DMA memory allocation and freeing. 2015-06-08T03:00:36Z Marcel Moolenaar marcel@FreeBSD.org 2015-06-08T03:00:36Z urn:sha1:5dcca8e800ee0bd6bede91a193c54681acff7f48 Slightly rework the tag handling. DMA support part 1: DMA tag create & destroy 2015-06-06T16:09:25Z Marcel Moolenaar marcel@FreeBSD.org 2015-06-06T16:09:25Z urn:sha1:4f027abddb02c5b6df045e359a96728b3cd7a09e Create a special resource (= device special file) for management of tags and maps, as well as for mapping memory into the address space. DMA resources are managed using the PROTO_IOC_BUSDMA ioctl. Part 1 implements tag creation, derivation and destruction. Add proto(4): A driver for prototyping and diagnostics. 2014-04-28T17:58:40Z Marcel Moolenaar marcel@FreeBSD.org 2014-04-28T17:58:40Z urn:sha1:67fb10f30cc61e1e29301db356dc81f4d30c3615 It exposes I/O resources to user space, so that programs can peek and poke at the hardware. It does not itself have knowledge about the hardware device it attaches to. Sponsored by: Juniper Networks, Inc.
