This patch updates the MMR register definitions for the SGI UV3 system. Note that because these definitions are automatically generated from the RTL we cannot control the length of the names. Therefore there are lines that exceed 80 characters. All the new MMR definitions are added in this patch. The patches that follow then update the references. The last patch is a "trim" patch which reduces the size of the MMR definitions file by about a third. This keeps "bi-sectability" in place as the intermediate patches would not compile correctly if the trimmed MMR defines were done first.

There was a mixup when the SGI UV2 hub chip was sent to be fabricated, and it ended up with the wrong part number in the HRP_NODE_ID mmr. Future versions of the chip will (may) have the correct part number. Change the UV infrastructure to recognize both part numbers as valid IDs of a UV2 hub chip.

No code changes. Reformat definitions to make it more readable. I fixed alignment of comments in the structure definitions. Also aligned comments and most field definitions & values. Also sorted the defines for the SHIFT & MASK values for each MMR. This make the file visually much more acceptable. Some of the symbol names are still quite long. The file is based on post-processing of verilog definitions that are used for the node controller chip design. Although some symbol names are not what I would chose, I would like to maintain compatibility with the names used by the chip designers. We have a number of cross-reference utilities & having common names is important.

This patch adds support for a new version of the SGI UV hub chip. The hub chip is the node controller that connects multiple blades into a larger coherent SSI. For the most part, UV2 is compatible with UV1. The majority of the changes are in the addresses of MMRs and in a few cases, the contents of MMRs. These changes are the result in changes in the system topology such as node configuration, processor types, maximum nodes, physical address sizes, etc. Signed-off-by: Jack Steiner <steiner@sgi.com> Link: http://lkml.kernel.org/r/20110511175028.GA18006@sgi.comSigned-off-by: Ingo Molnar <mingo@elte.hu>

This fixes problems seen on UV systems handling NMIs from the node controller. I isolated the "dazed..." messages that I saw earlier to a bug in the BMC on our platform. It was sending NMIs w/o properly setting a register that indicated the source of NMI. So rather than _assuming_ any unhandled NMI came from the UV system maintenance console (SMC), add a check to verify that the SMC actually sent the NMI.

This patch for SGI UV systems addresses a problem whereby interrupt transactions being looped back from a local IOH, through the hub to a local CPU can (erroneously) conflict with IO port operations and other transactions. To workaound this we set a high bit in the APIC IDs used for interrupts. This bit appears to be ignored by the sockets, but it avoids the conflict in the hub.

A new version of the SGI UV hub node controller is being developed. A few of the MMRs (control registers) that exist on the current hub no longer exist on the new hub. Fortunately, there are alternate MMRs that are are functionally equivalent and that exist on both hubs. This patch changes the UV code to use MMRs that exist in BOTH versions of the hub node controller.

This patch replaces a 'nop' uv_enable_timeouts() in the UV TLB shootdown code. (somehow, long ago that function got eviscerated) If any cpu in the destination node does not get interrupted by the message and post completion in a reasonable time the hardware should respond to the sender with an error. This function enables such timeouts. Tested on the UV hardware simulator.

This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>
