It is useful in applicationssuch as DPDK which perform some of their own memory management.Reviewed by: kib, jhb (previous version)MFC after: 2 weeksSponsored by: Juniper Networks, Inc.Sponsored by: Klara Inc.Differential Revision: https://reviews.freebsd.org/D26237 List of files: /freebsd-13.1/sys/arm64/include/memdev.h Wed, 02 Sep 2020 18:12:47 +0000 Mark Johnston <markj@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-13.1/sys/arm64/include/memdev.h#07b8a571 Add memmmap on arm64 so we can mmap /dev/mem and /dev/kmem.Obtained from: ABT Systems LtdMFC after: 1 weekSponsored by: The FreeBSD Foundation List of files: /freebsd-13.1/sys/arm64/include/memdev.h Wed, 13 Jul 2016 23:03:34 +0000 Andrew Turner <andrew@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-13.1/sys/arm64/include/memdev.h#e5acd89c Bring in the start of the arm64 kernel.This is only the minimum set of files needed to boot in qemu. As such it ismissing a few things.The bus_dma code is currently only stub functions with a full implementationfrom the development tree to follow.The gic driver has been copied as the interrupt framework is different. Itis expected the two drivers will be merged by the arm intrng project,however this will need to be imported into the tree and support for arm64would need to be added.This includes code developed by myself, SemiHalf, Ed Maste, and RobinRandhawa from ARM. This has been funded by the FreeBSD Foundation, withearly development by myself in my spare time with assistance from Robin.Differential Revision: https://reviews.freebsd.org/D2199Reviewed by: emaste, impRelnotes: yesSponsored by: The FreeBSD Foundation List of files: /freebsd-13.1/sys/arm64/include/memdev.h Mon, 13 Apr 2015 14:43:10 +0000 Andrew Turner <andrew@FreeBSD.org>
