MFC: FreeBSD/xbox support, as per the patch posted to arch@

2006-08-22T16:52:42Z

A kernel with 'options XBOX' will be bootable on a Microsoft Xbox (it will do nothing extra if booted on a non-xbox i386) The /sys/i386/conf/XBOX kernel configuration file contains a kernel with support for all XBOX peripherals. Approved by: imp (mentor) Reviewed by: arch@ (no objection)

Use a simpler implementation for the i8254 timecounter when using the lapic

timer since irq0 isn't being driven at hz in that case and we don't need to try to handle edge cases with rollover, etc. that require irq0 to be firing for the timecounter to actually work. Submitted by: phk Tested by: schweikh Approved by: re (scottl)

- Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) source

files after they were repo-copied to sys/dev/atkbdc. The sources of atkbdc(4) and its children were moved to the new location in preparation for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in order to not further scatter them over the whole tree which would have been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another reason for the repo-copies was that some of the sources were misfiled, e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly. Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't ISA-specific. - Separate the parts of atkbdc_isa.c which aren't actually ISA-specific but are shareable between different atkbdc(4) bus front-ends into atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource() respectively in atkbdc_isa.c instead of rolling own versions. - Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for atkbdc(4). PS/2 controllers and input devices are used on a couple of Sun OEM boards and occur on either the EBus or the ISA bus. Depending on the board it's either the only on-board mean to connect a keyboard and mouse or an alternative to either RS232 or USB devices. - Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled without isa(4) (e.g. for EBus-only machines). This ISA-specific part isn't separated into its own source file, yet, as it requires more work than was feasible for 6.0 in order to do it in a clean way. Actually philip@ is working on a rewrite of psm(4) so a more comprehensive clean-up and separation of hardware dependent and independent parts is expected to happen after 6.0.
