This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will not work on any real hardware (or fully work on any simulator). Much more needs to happen before this is actually functional but its nice to see the FreeBSD copyright message appear in the ia64 simulator.

Make sure bus space accesses use unorder memory loads and stores. Memory accesses are posted in program order by virtue of the uncacheable memory attribute. Since GCC, by default, adds acquire and release semantics to volatile memory loads and stores, we need to use inline assembly to guarantee it. With inline assembly, we don't need volatile pointers anymore. Itanium does not support semaphore instructions to uncacheable memory.

Add ia64_sync_i(), ia64_get_tpr() and ia64_set_tpr().

Next round of ia64 work, including fixes to context switching, implementing cpu_fork(), copy*str(), bcopy(), copy{in,out}(). With these changes, my test kernel reaches the mountroot prompt.

This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will not work on any real hardware (or fully work on any simulator). Much more needs to happen before this is actually functional but its nice to see the FreeBSD copyright message appear in the ia64 simulator.

In ia64_set_rr(), don't perform data serialization. This allows us to do the data serializations once after writing multiple region registers, as is done in pmap_switch(). All existing calls to ia64_set_rr() are followed with calls to ia64_srlz_d(). Approved by: re (blanket)

__asm __volatile("mov rr[%0]=%1"
Add data serialisations after ptc and mov to rr[] instructions.

Enable the high FP registers when we call the FPSWA handler and disable them again afterwards. This fixes a disabled FP fault while in the FPSWA handler. While here, merge the FP fault and FP trap handling code to reduce code duplication. Where code was different, it was not sure it should be. Trigger case: ports/math/atlas

* Various fixes to breakage introduced by the atomic and mutex reorgs. * Fixes to the signal delivery code. Not quite right yet. I would have preferred to wait until I have signal delivery actually working but the current kernel in CVS doesn't build.
