34 Support for 32-bit CloudABI executables can be compiled into the kernel
35 by adding this line to the kernel configuration file:
36 .Bd -ragged -offset indent
37 .Cd "options COMPAT_CLOUDABI32"
41 support for 64-bit CloudABI executables can be enabled by adding this
43 .Bd -ragged -offset indent
44 .Cd "options COMPAT_CLOUDABI64"
47 CloudABI support can also be loaded at boot time from
49 .Bd -literal -offset indent
55 CloudABI is a POSIX-like pure capability-based runtime environment,
58 It can be used to develop applications that are cross-platform,
60 and hardened against security exploits.
62 Support for CloudABI on
64 consists of three separate kernel modules.
67 kernel module implements all of the system calls that do not depend on
68 data structures that differ between hardware architectures.
74 kernel modules provide implementations of all of the machine-dependent
76 assuming that pointers stored in data structures are either 32 bits or
78 These modules also provide the image activators that load and start ELF
83 module can be loaded on any architecture supported by
87 module is only available on amd64, arm64, armv6, armv7 and i386.
88 The same holds for the
91 which is only available for amd64 and arm64.
93 A full cross compilation toolchain for CloudABI is available in the
94 .Pa devel/cloudabi-toolchain
98 .Pa sysutils/cloudabi-utils
103 can be used to safely execute CloudABI processes with access to a
104 restricted set of resources.
