61b993a34f 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

b47f51b4a0 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.

30eb8eda72 XLR PIC code update and style(9) fixes.
- style(9) fixes to mips/rmi platform files
- update pic.h to add pic_setup_intr() and use pic_setup_intr() for setting
  up interrupts which are routed thru PIC.
- remove rmi_spin_mutex_safe and haslock, and make sure that the functions
  are called only after mutexes are available.

5574a166c9 64 bit compilation support XLR platform code.
Mostly changes to make casting between int and pointer and printing
64bit values safe for 32 and 64 bit compile.

4542827d4d 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

6b9c94873a - Move rmi_pci_bus_space to header and avoid extern
- remove unused and commented code (MIPS_BUS_SPACE_PCI, pic_usb_ack)
- use rmi_pci_bus_space for USB too (needs byteswap)
- uncomment xls_ehci.c in files.xlr
- changes to xls_ehci.c - updated with dev/usb/controller/ehci_*.c as

019ee9781a Changes for pci and pci-e support
- add bus_space_rmi_pci.c for PCI bus space
- files.xlr update for changes in files
- pcibus.c merged into xlr_pci.c (they were small files with inter-dependencies)
- xlr_pci.c - lot of changes here with few fixes, formatting cleanup

748ad3c4ee adds rmi specific mips extensions file and makes sure
the includes point to the new place.

6e3272ee6f more Updates on the RMI code close to compiling now ;-) 2009-10-29 15:55:25 +00:00

257c916acf 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 ;-)
