More initial RMI files. Note that these so far do NOT compile and many of them may disappear. For example the xlr_boot1_console.c is old code that is ifdef'd out. I will clean these sorts of things up as I make progress on the port. So far the only thing I have I think straightened out is the bits around the interupt handling... and hey that may be broke ;-)

Clean up header files in RMI platform code (sys/mips/rmi), and remove unused files. - remove clock.c and clock.h, these are not used after the new timer code was added. - remove duplicated include files, fix header file ordering, remove some unneeded includes. - rename mips/rmi/shared_structs.h which contains the RMI boot loader interface to mips/rmi/rmi_boot_info.h. Remove unused files mips/rmi/shared_structs_func.h and sys/mips/rmi/shared_structs_offsets.h - merge mips/rmi/xlrconfig.h and mips/rmi/rmi_mips_exts.h, and remove duplicated functions. - nlge - minor change to remove unneeded argument. - Add FreeBSD svn keyword for headers

This pushes all of JC's patches that I have in place. I am now able to run 32 cores ok.. but I still will hang on buildworld with a NFS problem. I suspect I am missing a patch for the netlogic rge driver. JC check and see if I am missing anything except your core-mask changes Obtained from: JC

Some fixes to the current RMI interrupt handling, changes in this patch are: - (cleanup) remove rmi specific 'struct mips_intrhand' - this is no longer needed since 'struct intr_event' have all the required hooks - add xlr_cpu_establish_hardintr, which has args for pre/post ithread and filter hooks, so that the PCI code can add the PCI controller interrupt ack code here - make 'cpu_establish_hardintr' use the above function. - (fix) change type of eirr/eimr from register_t to uint64_t. These have to be 64bit otherwise we cannot handle interrupts from 32. - (fix) use eimr to mask eirr before checking interrupts, so that we will not handle masked interrupts. Obtained from: C.

/*
* XLR needs custom pre and post handlers for PCI/PCI-e interrupts
* XXX: maybe follow i386 intsrc model
*/
Revamp XLR interrupt handling, the previous scheme does not work well on SMP. We used to route all PIC based interrupts to cpu 0, and used the per-CPU interrupt mask to enable/disable interrupts. But the interrupt threads can run on any cpu on SMP, and the interrupt thread will re-enable the interrupts on the CPU it runs on when it is done, and not on cpu0 where the PIC will still send interrupts to. The fix is move the disable/enable for PIC based interrupts to PIC, we will ack on PIC only when the interrupt thread is done, and we do not use the per-CPU interrupt mask. The changes also introduce a way for subsystems to add a function that will be called to clear the interrupt on the subsystem. Currently This is used by the PCI/PCIe for doing additional work during the interrupt handling.
