Author: mav Date: Wed May 19 14:50:07 2010 New Revision: 208299 URL: http://svn.freebsd.org/changeset/base/208299 Log: MFC r207536, r207696, r208183: Import mvs(4) - Marvell 88SX50XX/88SX60XX/88SX70XX/SoC SATA controllers driver for CAM ATA subsystem. This driver supports same hardware as atamarvell, ataadaptec and atamvsata drivers from ata(4), but provides many additional features, such as NCQ, PMP, etc. Added: stable/8/share/man/man4/mvs.4 - copied unchanged from r207536, head/share/man/man4/mvs.4 stable/8/sys/dev/mvs/ - copied from r207536, head/sys/dev/mvs/ stable/8/sys/modules/mvs/ - copied from r207536, head/sys/modules/mvs/ Modified: stable/8/share/man/man4/Makefile stable/8/sys/arm/mv/files.mv stable/8/sys/conf/NOTES stable/8/sys/conf/files stable/8/sys/conf/kmod.mk stable/8/sys/dev/mvs/mvs.c stable/8/sys/modules/Makefile stable/8/sys/modules/mvs/Makefile Directory Properties: stable/8/share/man/man4/ (props changed) stable/8/sys/ (props changed) stable/8/sys/amd64/include/xen/ (props changed) stable/8/sys/cddl/contrib/opensolaris/ (props changed) stable/8/sys/contrib/dev/acpica/ (props changed) stable/8/sys/contrib/pf/ (props changed) stable/8/sys/dev/xen/xenpci/ (props changed) stable/8/sys/geom/sched/ (props changed) Modified: stable/8/share/man/man4/Makefile ============================================================================== --- stable/8/share/man/man4/Makefile Wed May 19 10:35:53 2010 (r208298) +++ stable/8/share/man/man4/Makefile Wed May 19 14:50:07 2010 (r208299) @@ -218,6 +218,7 @@ MAN= aac.4 \ msk.4 \ mtio.4 \ multicast.4 \ + mvs.4 \ mwl.4 \ mwlfw.4 \ mxge.4 \ Copied: stable/8/share/man/man4/mvs.4 (from r207536, head/share/man/man4/mvs.4) ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ stable/8/share/man/man4/mvs.4 Wed May 19 14:50:07 2010 (r208299, copy of r207536, head/share/man/man4/mvs.4) @@ -0,0 +1,176 @@ +.\" Copyright (c) 2009 Alexander Motin <mav@FreeBSD.org> +.\" All rights reserved. +.\" +.\" Redistribution and use in source and binary forms, with or without +.\" modification, are permitted provided that the following conditions +.\" are met: +.\" 1.
