-.Dt GEOM_MAP 4
-.Os
-.Sh NAME
-.Nm geom_map
-.Nd "GEOM module that maps defined items as separate partitions"
-.Sh SYNOPSIS
-To compile this driver into the kernel,
-place the following line in your
-kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "options geom_map"
-.Ed
-.Sh DESCRIPTION
-The
-.Nm
-framework provides support for mapping defined parts of the media.
-Basically it is helpful for embedded devices where in the one continuous
-flash are loader, kernel and rootfs parts.
-.Nm
-allows making them available as separate parts and protects the loader from
-being overwritten.
-.Pp
-At boot time
-.Nm
-partitions are listed (only with bootverbose) as:
-.Bd -literal -offset indent
-MAP: 0x30000, data=0x30000 "/dev/map/bootloader"
-MAP: 30000x10000, data=0x10000 "/dev/map/factory"
-MAP: 40000x7a0000, data=0x7a0000 "/dev/map/upgrade"
-MAP: search key ".!/bin/sh" from 0x100000, step 0x10000
-MAP: 40000x110000, data=0x110000 "/dev/map/kernel"
-MAP: search key ".!/bin/sh" from 0x100000, step 0x10000
-MAP: 150000x690000, data=0x690000 "/dev/map/rootfs"
-MAP: 7e0000x20000, data=0x20000 "/dev/map/config"
-.Ed
-.Pp
-The current
-.Nm
-configuration can be accessed with the following
-.Xr sysctl 8
-nodes:
-.Va kern.geom.conftxt , kern.geom.confxml ,
-and
-.Va kern.geom.confdot
-or by using
-.Dq Li "geom map list" .
-.Bd -literal -offset indent
-# sysctl -n kern.geom.conftxt
-0 MD md0 10485760 512 u 0 s 512 f 0 fs 0 l 10485760 t malloc
-0 DISK cfid0 8388608 4 hd 0 sc 0
-1 MAP map/config 131072 4 i 5 o 8257536 entry 0 dsize 131072
-1 MAP map/rootfs 6881280 4 i 4 o 1376256 entry 0 dsize 6881280
-2 UZIP map/rootfs.uzip 18677760 512
-1 MAP map/kernel 1114112 4 i 3 o 262144 entry 0 dsize 1114112
-1 MAP map/upgrade 7995392 4 i 2 o 262144 entry 0 dsize 7995392
-1 MAP map/factory 65536 4 i 1 o 196608 entry 0 dsize 65536
-1 MAP map/bootloader 196608 4 i 0 o 0 entry 0 dsize 196608
-.Ed
-.Pp
-Driver configuration can be done in
-.Xr device.hints 5 .
-List of used parameters:
-.Bl -tag -width indent
-.It Va at
-select media to attach
-.It Va name
-name of partition (will create device
-.Pa /dev/map/ Ns Ar that_name )
-.It Va start
-offset from the beginning of the parent media to start of the mapped partition.
-This field can also have a special value
-.Qq Li search: Ns Ar searchstart Ns Li : Ns Ar searchstep Ns Li : Ns Ar searchkey ,
-where:
-.Bl -tag -width indent
-.It Ar searchstart
-offset from the beginning of the parent media where search will be started
-.It Ar searchstep
-value of the increment used while searching for the partition boundary markers
-.It Ar searchkey
-key which will be used to find partition boundary markers.
-The wildcard
-.Ql .\&
-can be used to match any character on that position
-.El
-.It Va end
-offset from the beginning of the parent media to the end of the mapped partition.
-This field can also have the special value
-.Qq Li search: Ns Ar searchstart Ns Li : Ns Ar searchstep Ns Li : Ns Ar searchkey ,
-as described above.
-.It Va offset
-offset where the data of the mapped partition begins
-.El
-.Pp
-Each record contains the start address (in bytes) from the media begin, size
-(in bytes), offset where the data of mapped partition begins, and the name of
-new device.
-.Bd -literal -offset indent
-MAP: 150000x690000, data=0x690000 "/dev/map/rootfs"
-.Ed
-.Bd -literal
-00150000 - start address
-00690000 - size
-00000000 - data begin from zero offset
-00690000 - data size
-"map/rootfs" - new media will be accessible via /dev/map/rootfs dev.
-.Ed
-.Sh EXAMPLES
-If we need to implement layout shown above, we need to define the following
-hints:
-.Bd -literal -offset indent
-hint.map.0.at="cfid0"
-hint.map.0.start=0x00000000
-hint.map.0.end=0x00030000
-hint.map.0.name="bootloader"
-hint.map.0.readonly=1
-.Ed
-.Pp
-This defines
-.Pa /dev/map/bootloader
-at disk
-.Pa cfid0
-starting at
-.Li 0x00000000
-and ending at
-.Li 0x00030000 ,
-it is also marked as readonly.
-.Bd -literal -offset indent
-hint.map.1.at="cfid0"
-hint.map.1.start=0x00030000
-hint.map.1.end=0x00040000
-hint.map.1.name="factory"
-
-hint.map.2.at="cfid0"
-hint.map.2.start=0x00040000
-hint.map.2.end=0x007e0000
-hint.map.2.name="upgrade"
-
-hint.map.3.at="cfid0"
-hint.map.3.name="kernel"
-hint.map.3.start=0x00040000
-hint.map.3.end="search:0x00100000:0x10000:.!/bin/sh"
-.Ed
-.Pp
-This defines
-.Pa /dev/map/kernel
-at disk
-.Pa cfid0
-starting at
-.Li 0x00040000 ,
-but the end position must be searched by finding the key
-.Dq Li ".!/bin/sh" ,
-from offset
-.Li 0x00100000
-to the end of media with step
-.Li 0x10000 .
-The real marker in this case is
-.Dq Li "#!/bin/sh" ,
-but
-.Ql #
-terminates the line when the hints file is parsed, so we need to use wildcard
-.Ql .\&
-instead of
-.Ql # .
-.Bd -literal -offset indent
-hint.map.4.at="cfid0"
-hint.map.4.name="rootfs"
-hint.map.4.start="search:0x00100000:0x10000:.!/bin/sh"
-hint.map.4.end=0x007e0000
-
-hint.map.5.at="cfid0"
-hint.map.5.start=0x007e0000
-hint.map.5.end=0x00800000
-hint.map.5.name="config"
