Create a default kernel config for i386 and move 'device isa' and 'device npx' (both of which aren't really optional right now) and 'device io' and 'device mem' (to preserve POLA for 4.x users upgrading to 6.0) from GENERIC into DEFAULTS.

- Allow duplicate "machine" directives with the same arguments. - Move existing "machine" directives to DEFAULTS. 2005-11-27 23:17:00 +00:00			`machine i386`

Add the ability to subset the devices that UART pulls in. This allows the arm to compile without all the extras that don't appear, at least not in the flavors of ARM I deal with. This helps us save about 100k. If I've botched the available devices on a platform, please let me know and I'll correct ASAP. 2006-06-12 04:21:50 +00:00

Add 'options KSE' to the kernel config DEFAULTS on all arches/machines except sun4v. This change makes the transition from a default to an option more transparent and is an attempt to head off all the compliants that are likely from people who don't read UPDATING, based on experience with the io/mem change.

Use default options for default partitioning schemes, rather than making the relevant files standard. This avoids duplication and makes it easier to override/disable unwanted schemes. Since ARM doesn't have a DEFAULTS configuration file, leave the source files for the BSD and MBR partitioning schemes in files.arm for now. 2007-06-11 00:38:06 +00:00			`# Default partitioning schemes`
Make gpart the default partitioning class on all platforms. Both ia64 and powerpc were using gpart exclusively already so there's no change for those two. Discussed on: arch@ 2008-12-17 17:43:22 +00:00			`options GEOM_PART_BSD`
Add option GEOM_PART_EBR by default on amd64 and i386. 2009-02-10 00:08:39 +00:00			`options GEOM_PART_EBR`
Add a compat option to the EBR scheme that controls the naming of the partitions (GEOM_PART_EBR_COMPAT). When compatibility is enabled, changes to the partitioning are disallowed. Remove the device name aliasing added previously to provide backward compatibility, but which in practice doesn't give us anything. Enable compatibility on amd64 and i386. 2009-04-15 22:38:22 +00:00			`options GEOM_PART_EBR_COMPAT`
