--enable-smp Enable SMP support
--enable-x86-sep Enable x86 SEP instructions for issuing syscalls
--enable-x86-tsc Enable x86 TSC for timings
- --enable-arm-tsc Select for which machine we are compiling. Valid
- machines are at91, kuser, imx, ixp4xx, omap, orion,
- pxa, s3c24x, sa1100.
+ --enable-arm-tsc You only need this option if you get the following
+ message when starting an application: Xenomai:
+ incompatible feature set (userland requires
+ "kuser_tsc ...", kernel provides "...",
+ missing="kuser_tsc"). In that case, this option
+ allows to select the machine for which a user-space

+ s3c24x, sa1100.
--enable-arm-quirks Enable quirks for specific systems. Currently
supported quirks are for sa1100 and xscale3.
--disable-doc-install Do not install documentation
