1104442832 Fixes in the XLR platform code
- Fix bug in pic.h, assign reg variable, before return.
- In xlr_pci.c, need to ignore the result of mmio read.

da4dad492d XLS B0 revision PCI support and related changes.
- XLS B0 and later revision chips have PCIe link 2 & 3 mapped to different
  PIC interrupts. Update pic.h, board.h and xlr_pci.c to reflect this.
- remove debug prints in xlr_pci.c
- add more processor IDs to board.h, add function xlr_is_xls_b0()
- some style(9) and whitespace fixes

833182b77e Updates for the RMI MIPS platform code
- set cache_coherent_dma flag in cpuinfo for XLR, this will make sure that
  BUS_DMA_COHERENT flag is handled correctly in busdma_machdep.c
- iodi.c, call device_get_name() just once
- clear RMI specific EIRR while intializing CPUs
- remove debug print in intr_machdep.c

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.

867a12afe1 Provide timecounter based on XLR PIC timer.
- Use timer 7 in XLR PIC as a 32 counter
- provide pic_init_timer(), pic_set_timer(), pic_timer_count32() and
  pic_timer_count() PIC timer operations.
- register this timer as platform_timecounter on rmi platform.

f6f7fc21c4 XLR PIC code update.
- Fix a bug in xlr_pic_init (use irq in PIC_IRQ_IS_EDGE_TRIGGERED)
- use new macro PIC_INTR_TO_IRQ() and PIC_IRT_x() in xlr_pic_init

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.

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

e015b3b4f0 To prevent a LOR we need to pass in
a lock flag in the pic routines. In
some places we hold the pic lock, others
we do not.

7a7f91f61b ok we now get so that the uart init's and we can print. We
cannot set baud rate as they did in 6.4, this hoses things and
we loose our 38400 default term.

We now lock somewhere in tcinit.

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 ;-)
