+ * Each BOARD consists of COMPONENTs and the BOARD structure has 
+ * pointers (offsets) to its COMPONENT structure.
+ * The COMPONENT structure has version info, size and speed info, revision,
+ * error info and the NIC info. This structure can accommodate any
+ * BOARD with arbitrary COMPONENT composition.
+ *
+ * The ERRORINFO part of each BOARD has error information
+ * that describes errors about the BOARD itself. It also has flags to
+ * indicate the COMPONENT(s) on the board that have errors. The error 
+ * information specific to the COMPONENT is present in the respective 
+ * COMPONENT structure.
+ *
+ * The ERRORINFO structure is also treated like a COMPONENT, ie. the 
+ * BOARD has pointers(offset) to the ERRORINFO structure. The rboard
+ * structure also has a pointer to the ERRORINFO structure. This is 
+ * the place to store ERRORINFO about a REMOTE NODE, if the HUB on
+ * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where 
+ * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
+ * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info 
+ * which is present on the REMOTE NODE.(TBD)
+ * REMOTE ERRINFO can be stored on any of the nearest nodes 
+ * or on all the nearest nodes.(TBD)
+ * Like BOARD structures, REMOTE ERRINFO structures can be built locally
+ * using the rboard errinfo pointer.
+ *
+ * In order to get useful information from this Data organization, a set of
+ * interface routines are provided (TBD). The important thing to remember while
+ * manipulating the structures, is that, the NODE number information should
+ * be used. If the NODE is non-zero (remote) then each offset should
+ * be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR. 
+ * This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
+ * 
+ * Note that these structures do not provide much info about connectivity.
+ * That info will be part of HWGRAPH, which is an extension of the cfg_t
+ * data structure. (ref IP27prom/cfg.h) It has to be extended to include
+ * the IO part of the Network(TBD).
+ *
+ * The data structures below define the above concepts.

+ * PIC AS DEVICE ZERO
+ * ------------------
+ *
+ * PIC handles PCI/X busses.  PCI/X requires that the 'bridge' (i.e. PIC)
+ * be designated as 'device 0'.   That is a departure from earlier SGI
+ * PCI bridges.  Because of that we use config space 1 to access the
+ * config space of the first actual PCI device on the bus.
+ * Here's what the PIC manual says:
+ *
+ *     The current PCI-X bus specification now defines that the parent
+ *     hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
+ *     reduced the total number of devices from 8 to 4 and removed the
+ *     device registers and windows, now only supporting devices 0,1,2, and
+ *     3. PIC did leave all 8 configuration space windows. The reason was
+ *     there was nothing to gain by removing them. Here in lies the problem.
+ *     The device numbering we do using 0 through 3 is unrelated to the device
+ *     numbering which PCI-X requires in configuration space. In the past we
+ *     correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
+ *     PCI-X requires we start a 1, not 0 and currently the PX brick
+ *     does associate our:
+ *
+ *         device 0 with configuration space window 1,
+ *         device 1 with configuration space window 2,
+ *         device 2 with configuration space window 3,
+ *         device 3 with configuration space window 4.
+ *
+ * The net effect is that all config space access are off-by-one with
+ * relation to other per-slot accesses on the PIC.
+ * Here is a table that shows some of that:
+ *
+ *                               Internal Slot#
+ *           |

+ * Description:  This register's value is a bit vector that guards      *
+ * access to local registers within the II as well as to external       *
+ * Crosstalk widgets. Each bit in the register corresponds to a         *
+ * particular region in the system; a region consists of one, two or    *
+ * four nodes (depending on the value of the REGION_SIZE field in the   *
+ * LB_REV_ID register, which is documented in Section 8.3.1.1). The     *
+ * protection provided by this register applies to PIO read             *
+ * operations as well as PIO write operations. The II will perform a    *
+ * PIO read or write request only if the bit for the requestor's        *
+ * region is set; otherwise, the II will not perform the requested      *
+ * operation and will return an error response. When a PIO read or      *
+ * write request targets an external Crosstalk widget, then not only    *
+ * must the bit for the requestor's region be set in the ILAPR, but     *
+ * also the target widget's bit in the IOWA register must be set in     *
+ * order for the II to perform the requested operation; otherwise,      *
+ * the II will return an error response. Hence, the protection          *
+ * provided by the IOWA register supplements the protection provided    *
+ * by the ILAPR for requests that target external Crosstalk widgets.    *
+ * This register itself can be accessed only by the nodes whose         *
+ * region ID bits are enabled in this same register. It can also be     *
+ * accessed through the IAlias space by the local processors.           *

+ * The register also contains the Read Response Timeout values. The     *
+ * Prescalar is 23 bits, and counts II clocks. An internal counter      *
+ * increments on every II clock and when it reaches the value in the    *
+ * Prescalar field, all IPRTE registers with their valid bits set       *

+ * legitimate write to this register will set the Busy bit, clear the   *

+ * While the transfer is in progress, hardware will decrement the       *
+ * length field with each successful block that is copied. Once the     *
+ * transfer completes, hardware will clear the Busy bit. The length     *
+ * field will also contain the number of cache lines left to be         *
+ * transferred.                                                         *

+ *  Definitions of terms (these definitions are for IA64 ONLY. Other architectures
+ *  use cpuid/cpunum quite defferently):
+ *
+ *         CPUID - a number in range of 0..NR_CPUS-1 that uniquely identifies
+ *              the cpu. The value cpuid has no significance on IA64 other than
+ *              the boot cpu is 0.
+ *                      smp_processor_id() returns the cpuid of the current cpu.
+ *
+ *         CPU_PHYSICAL_ID (also known as HARD_PROCESSOR_ID)
+ *              This is the same as 31:24 of the processor LID register
+ *                      hard_smp_processor_id()- cpu_physical_id of current processor
+ *                      cpu_physical_id(cpuid) - convert a <cpuid> to a <physical_cpuid>
+ *                      cpu_logical_id(phy_id) - convert a <physical_cpuid> to a <cpuid> 
+ *                              * not real efficient - don't use in perf critical code
+ *
+ *         SLICE - a number in the range of 0 - 3 (typically) that represents the
+ *              cpu number on a brick.
+ *
+ *         SUBNODE - (almost obsolete) the number of the FSB that a cpu is
+ *              connected to. This is also the same as the PI number. Usually 0 or 1.
+ *
+ *      NOTE!!!: the value of the bits in the cpu physical id (SAPICid or LID) of a cpu has no 
+ *      significance. The SAPIC id (LID) is a 16-bit cookie that has meaning only to the PROM.
+ *
+ *

+/*
+ * DMA space
+ *
+ * The CA aperature (ie. bus address range) mapped by the GART is segmented into
+ * two parts.  The lower portion of the aperature is used for mapping 32 bit
+ * PCI addresses which are managed by the dma interfaces in this file.  The
+ * upper poprtion of the aperature is used for mapping 48 bit AGP addresses.
+ * The AGP portion of the aperature is managed by the agpgart_be.c driver
+ * in drivers/linux/agp.  There are ca-specific hooks in that driver to
+ * manipulate the gart, but management of the AGP portion of the aperature
+ * is the responsibility of that driver.
+ *
+ * CA allows three main types of DMA mapping:
+ *
+ * PCI 64-bit   Managed by this driver
+ * PCI 32-bit   Managed by this driver
+ * AGP 48-bit   Managed by hooks in the /dev/agpgart driver
+ *
+ * All of the above can optionally be remapped through the GART.  The following
+ * table lists the combinations of addressing types and GART remapping that
+ * is currently supported by the driver (h/w supports all, s/w limits this):
+ *
+ *              PCI64           PCI32           AGP48
+ * GART         no              yes             yes
+ * Direct       yes             yes             no
+ *
+ * GART remapping of PCI64 is not done because there is no need to.  The
+ * 64 bit PCI address holds all of the information necessary to target any
+ * memory in the system.
+ *
+ * AGP48 is always mapped through the GART.  Management of the AGP48 portion
+ * of the aperature is the responsibility of code in the agpgart_be driver.
+ *
+ * The non-64 bit bus address space will currently be partitioned like this:
+ *
+ *      0xffff_ffff_ffff        +--------
+ *                              | AGP48 direct
+ *                              | Space managed by this driver
+ *      CA_AGP_DIRECT_BASE      +--------
+ *                              | AGP GART mapped (gfx aperature)
+ *                              | Space managed by /dev/agpgart driver
+ *                              | This range is exposed to the agpgart
+ *                              | driver as the "graphics aperature"
+ *      CA_AGP_MAPPED_BASE      +-----
+ *                              | PCI GART mapped
+ *                              | Space managed by this driver          
+ *      CA_PCI32_MAPPED_BASE    +----
+ *                              | PCI32 direct
+ *                              | Space managed by this driver
+ *      0xC000_0000             +--------
+ *      (CA_PCI32_DIRECT_BASE)
+ *
+ * The bus address range CA_PCI32_MAPPED_BASE through CA_AGP_DIRECT_BASE
+ * is what we call the CA aperature.  Addresses falling in this range will
+ * be remapped using the GART.
+ *
+ * The bus address range CA_AGP_MAPPED_BASE through CA_AGP_DIRECT_BASE
+ * is what we call the graphics aperature.  This is a subset of the CA
+ * aperature and is under the control of the agpgart_be driver.
+ *
+ * CA_PCI32_MAPPED_BASE, CA_AGP_MAPPED_BASE, and CA_AGP_DIRECT_BASE are
+ * somewhat arbitrary values.  The known constraints on choosing these is:
+ *
+ * 1)  CA_AGP_DIRECT_BASE-CA_PCI32_MAPPED_BASE+1 (the CA aperature size)
+ *     must be one of the values supported by the ca_gart_aperature register.
+ *     Currently valid values are: 4MB through 4096MB in powers of 2 increments
+ *
+ * 2)  CA_AGP_DIRECT_BASE-CA_AGP_MAPPED_BASE+1 (the gfx aperature size)
+ *     must be in MB units since that's what the agpgart driver assumes.
+ */
+
+/*
+ * Define Bus DMA ranges.  These are configurable (see constraints above)
+ * and will probably need tuning based on experience.
+ */
+
+
+/*
+ * 11/24/03
+ * CA has an addressing glitch w.r.t. PCI direct 32 bit DMA that makes it
+ * generally unusable.  The problem is that for PCI direct 32 
+ * DMA's, all 32 bits of the bus address are used to form the lower 32 bits
+ * of the coretalk address, and coretalk bits 38:32 come from a register.
+ * Since only PCI bus addresses 0xC0000000-0xFFFFFFFF (1GB) are available
+ * for DMA (the rest is allocated to PIO), host node addresses need to be
+ * such that their lower 32 bits fall in the 0xC0000000-0xffffffff range
+ * as well.  So there can be no PCI32 direct DMA below 3GB!!  For this
+ * reason we set the CA_PCI32_DIRECT_SIZE to 0 which essentially makes
+ * tioca_dma_direct32() a noop but preserves the code flow should this issue
+ * be fixed in a respin.
+ *
+ * For now, all PCI32 DMA's must be mapped through the GART.

+ * This file defines various macros to transfer memory areas across
+ * the user/kernel boundary.  This needs to be done carefully because
+ * this code is executed in kernel mode and uses user-specified
+ * addresses.  Thus, we need to be careful not to let the user to
+ * trick us into accessing kernel memory that would normally be
+ * inaccessible.  This code is also fairly performance sensitive,
+ * so we want to spend as little time doing safety checks as
+ * possible.
+ *
+ * To make matters a bit more interesting, these macros sometimes also
+ * called from within the kernel itself, in which case the address
+ * validity check must be skipped.  The get_fs() macro tells us what
+ * to do: if get_fs()==USER_DS, checking is performed, if
+ * get_fs()==KERNEL_DS, checking is bypassed.
+ *
+ * Note that even if the memory area specified by the user is in a
+ * valid address range, it is still possible that we'll get a page
+ * fault while accessing it.  This is handled by filling out an
+ * exception handler fixup entry for each instruction that has the
+ * potential to fault.  When such a fault occurs, the page fault
+ * handler checks to see whether the faulting instruction has a fixup
+ * associated and, if so, sets r8 to -EFAULT and clears r9 to 0 and
+ * then resumes execution at the continuation point.

+ * Core file format: The core file is written in such a way that gdb

+ *
+ *  upage: 1 page consisting of a user struct that tells gdb
+ *      what is present in the file.  Directly after this is a
+ *      copy of the task_struct, which is currently not used by gdb,
+ *      but it may come in handy at some point.  All of the registers
+ *      are stored as part of the upage.  The upage should always be
+ *      only one page long.
+ *  data: The data segment follows next.  We use current->end_text to
+ *      current->brk to pick up all of the user variables, plus any memory
+ *      that may have been sbrk'ed.  No attempt is made to determine if a
+ *      page is demand-zero or if a page is totally unused, we just cover
+ *      the entire range.  All of the addresses are rounded in such a way
+ *      that an integral number of pages is written.
+ *  stack: We need the stack information in order to get a meaningful
+ *      backtrace.  We need to write the data from usp to
+ *      current->start_stack, so we round each of these in order to be able
+ *      to write an integer number of pages.

+ * Addressing Terminology
+ *
+ *      M       - The low M bits of a physical address represent the offset
+ *                into the blade local memory. RAM memory on a blade is physically
+ *                contiguous (although various IO spaces may punch holes in
+ *                it)..
+ *
+ *      N       - Number of bits in the node portion of a socket physical
+ *                address.
+ *
+ *      NASID   - network ID of a router, Mbrick or Cbrick. Nasid values of
+ *                routers always have low bit of 1, C/MBricks have low bit
+ *                equal to 0. Most addressing macros that target UV hub chips
+ *                right shift the NASID by 1 to exclude the always-zero bit.
+ *                NASIDs contain up to 15 bits.
+ *
+ *      GNODE   - NASID right shifted by 1 bit. Most mmrs contain gnodes instead
+ *                of nasids.
+ *
+ *      PNODE   - the low N bits of the GNODE. The PNODE is the most useful variant
+ *                of the nasid for socket usage.
+ *
+ *
+ *  NumaLink Global Physical Address Format:
+ *  +--------------------------------+---------------------+
+ *  |00..000|      GNODE             |      NodeOffset     |
