+ * Each PTE in a process VM's page table is either:
+ *   "present" -- valid and not swapped out, protection bits are meaningful;
+ *   "not present" -- which further subdivides in these two cases:
+ *      "none" -- no mapping at all; identified by pte_none(), set by pte_clear(
+ *      "swapped out" -- the page is swapped out, and the SWP macros below
+ *                      are used to store swap file info in the PTE itself.
+ *
+ * In the Xtensa processor MMU, any PTE entries in user space (or anywhere
+ * in virtual memory that can map differently across address spaces)
+ * must have a correct ring value that represents the RASID field that
+ * is changed when switching address spaces.  Eg. such PTE entries cannot
+ * be set to ring zero, because that can cause a (global) kernel ASID
+ * entry to be created in the TLBs (even with invalid cache attribute),
+ * potentially causing a multihit exception when going back to another
+ * address space that mapped the same virtual address at another ring.
+ *
+ * SO: we avoid using ring bits (_PAGE_RING_MASK) in "not present" PTEs.
+ * We also avoid using the _PAGE_VALID bit which must be zero for non-present
+ * pages.
+ *
+ * We end up with the following available bits:  1..3 and 7..31.
+ * We don't bother with 1..3 for now (we can use them later if needed),
+ * and chose to allocate 6 bits for SWP_TYPE and the remaining 19 bits
+ * for SWP_OFFSET.  At least 5 bits are needed for SWP_TYPE, because it
+ * is currently implemented as an index into swap_info[MAX_SWAPFILES]
+ * and MAX_SWAPFILES is currently defined as 32 in <linux/swap.h>.
+ * However, for some reason all other architectures in the 2.4 kernel
+ * reserve either 6, 7, or 8 bits so I'll not detract from that for now.  :)
+ * SWP_OFFSET is an offset into the swap file in page-size units, so
+ * with 4 kB pages, 19 bits supports a maximum swap file size of 2 GB.
+ *
+ * FIXME:  2 GB isn't very big.  Other bits can be used to allow
+ * larger swap sizes.  In the meantime, it appears relatively easy to get
+ * around the 2 GB limitation by simply using multiple swap files.

+/* Tensilica's xt-xcc compiler is much more agressive at code
+ * optimization than gcc.  Multiple __asm__ statements are
+ * insufficient for xt-xcc because subsequent optimization passes
+ * (beyond the front-end that knows of __asm__ statements and other
+ * such GNU Extensions to C) can modify the register selection for
+ * containment of C variables.
+ *
+ * xt-xcc cannot modify the contents of a single __asm__ statement, so
+ * we create single-asm versions of the syscall macros that are
+ * suitable and optimal for both xt-xcc and gcc.
+ *
+ * Linux takes system-call arguments in registers.  The following
+ * design is optimized for user-land apps (e.g., glibc) which
+ * typically have a function wrapper around the "syscall" assembly
+ * instruction.  It satisfies the Xtensa ABI while minizing argument
+ * shifting.
+ *
+ * The Xtensa ABI and software conventions require the system-call
+ * number in a2.  If an argument exists in a2, we move it to the next
+ * available register.  Note that for improved efficiency, we do NOT
+ * shift all parameters down one register to maintain the original
+ * order.
+ *
+ * At best case (zero arguments), we just write the syscall number to
+ * a2.  At worst case (1 to 6 arguments), we move the argument in a2
+ * to the next available register, then write the syscall number to
+ * a2.
+ *
+ * For clarity, the following truth table enumerates all possibilities.
+ *
+ * arguments    syscall number  arg0, arg1, arg2, arg3, arg4, arg5
+ * ---------    --------------  ----------------------------------
+ *      0             a2

+ *
+ *  Minimum entries per way (ie. per associativity) = 1024 / 64 / 4 = 4

+ *  cacheattr_set
+ *      Writes both I-cache and D-cache CACHEATTRs from a2 (a3-a8 clobbered).
+ *      Works even when changing one's own code's attributes.
+ *
+ *  icacheattr_is_enabled  label

+ *  General notes on MMU parameters.
+ *
+ *  Terminology:
+ *      ASID = address-space ID (acts as an "extension" of virtual addresses)
+ *      VPN  = virtual page number
+ *      PPN  = physical page number
+ *      CA   = encoded cache attribute (access modes)
+ *      TLB  = translation look-aside buffer (term is stretched somewhat here)
+ *      I    = instruction (fetch accesses)
+ *      D    = data (load and store accesses)
+ *      way  = each TLB (ITLB and DTLB) consists of a number of "ways"
+ *              that simultaneously match the virtual address of an access;
+ *              a TLB successfully translates a virtual address if exactly
+ *              one way matches the vaddr; if none match, it is a miss;
+ *              if multiple match, one gets a "multihit" exception;
+ *              each way can be independently configured in terms of number of
+ *              entries, page sizes, which fields are writable or constant, etc.
+ *      set  = group of contiguous ways with exactly identical parameters
+ *      ARF  = auto-refill; hardware services a 1st-level miss by loading a PTE
+ *              from the page table and storing it in one of the auto-refill ways;
+ *              if this PTE load also misses, a miss exception is posted for s/w.
+ *      min-wired = a "min-wired" way can be used to map a single (minimum-sized)
+ *              page arbitrarily under program control; it has a single entry,
+ *              is non-auto-refill (some other way(s) must be auto-refill),
+ *              all its fields (VPN, PPN, ASID, CA) are all writable, and it
+ *              supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current
+ *              restriction is that this be the only page size it supports).
+ *
+ *  TLB way entries are virtually indexed.
+ *  TLB ways that support multiple page sizes:
+ *      - must have all writable VPN and PPN fields;
+ *      - can only use one page size at any given time (eg. setup at startup),
+ *        selected by the respective ITLBCFG or DTLBCFG special register,
+ *        whose bits n*4+3 .. n*4 index the list of page sizes for way n
+ *        (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n);
+ *        this list may be sparse for auto-refill ways because auto-refill
+ *        ways have independent lists of supported page sizes sharing a
+ *        common encoding with PTE entries; the encoding is the index into
+ *        this list; unsupported sizes for a given way are zero in the list;
+ *        selecting unsupported sizes results in undefined hardware behaviour;
+ *      - is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition).

+ *      <as> = value whose most significant set bit is to be found
+ *      <at> = undefined
+ *      no other registers are used by this macro.
+ *  On exit:

+ *  floop, floopnez, floopgtz, floopend
+ *
+ *  These macros are used for fast inner loops that
+ *  work whether or not the Loops options is configured.
+ *  If the Loops option is configured, they simply use
+ *  the zero-overhead LOOP instructions; otherwise
+ *  they use explicit decrement and branch instructions.
+ *
+ *  They are used in pairs, with floop, floopnez or floopgtz
+ *  at the beginning of the loop, and floopend at the end.
+ *
+ *  Each pair of loop macro calls must be given the loop count
+ *  address register and a unique label for that loop.
+ *
+ *  Example:
+ *
+ *      movi     a3, 16     // loop 16 times
+ *      floop    a3, myloop1
+ *      :
+ *      bnez     a7, end1       // exit loop if a7 != 0
+ *      :
+ *      floopend a3, myloop1
+ *  end1:
+ *
+ *  Like the LOOP instructions, these macros cannot be
+ *  nested, must include at least one instruction,
+ *  cannot call functions inside the loop, etc.
+ *  The loop can be exited by jumping to the instruction
+ *  following floopend (or elsewhere outside the loop),
+ *  or continued by jumping to a NOP instruction placed
+ *  immediately before floopend.
+ *
+ *  Unlike LOOP instructions, the register passed to floop*
+ *  cannot be used inside the loop, because it is used as
+ *  the loop counter if the Loops option is not configured.
+ *  And its value is undefined after exiting the loop.
+ *  And because the loop counter register is active inside
+ *  the loop, you can't easily use this construct to loop
+ *  across a register file using ROTW as you might with LOOP
+ *  instructions, unless you copy the loop register along.

+ *  window_spill{4,8,12}

+ *  These macros spill callers' register windows to the stack.
+ *  They work for both privileged and non-privileged tasks.
+ *  Must be called from a windowed ABI context, eg. within
+ *  a windowed ABI function (ie. valid stack frame, window
+ *  exceptions enabled, not in exception mode, etc).
+ *
+ *  This macro requires a single invocation of the window_spill_common
+ *  macro in the same assembly unit and section.
+ *
+ *  Note that using window_spill{4,8,12} macros is more efficient
+ *  than calling a function implemented using window_spill_function,
+ *  because the latter needs extra code to figure out the size of
+ *  the call to the spilling function.
+ *
+ *  Example usage:
+ *
+ *              .text
+ *              .align  4
+ *              .global some_function

+ *      some_function:
+ *              entry   a1, 16
+ *              :
+ *              :
+ *

+ *                              // to use window_spill{8,12} in this example function we'd have
+ *                              // to increase space allocated by the entry instruction, because
+ *                              // 16 bytes only allows call4; 32 or 48 bytes (+locals) are needed
+ *                              // for call8/window_spill8 or call12/window_spill12 respectively.
+ *              :
+ *
+ *              retw
+ *
+ *              window_spill_common     // instantiates code used by window_spill4

+ *  System call like services offered by the simulator host.

+ *  for Xtensa processors.  However not all system calls and
+ *  not all functionality of a given system call are implemented,
+ *  or necessarily have well defined or equivalent semantics in
+ *  the context of a simulation (as opposed to a Unix kernel).
+ *
+ *  These services behave largely as if they had been invoked
+ *  as a task in the simulator host's operating system
+ *  (eg. files accessed are those of the simulator host).
+ *  However, these SIMCALLs model a virtual operating system
+ *  so that various definitions, bit assignments etc
+ *  (eg. open mode bits, errno values, etc) are independent
+ *  of the host operating system used to run the simulation.
+ *  Rather these definitions are specific to the Xtensa ISS.
+ *  This way Xtensa ISA code written to use these SIMCALLs
+ *  can (in principle) be simulated on any host.
+ *
+ *  Up to 6 parameters are passed in registers a3 to a8
+ *  (note the 6th parameter isn't passed on the stack,
+ *   unlike windowed function calling conventions).
+ *  The return value is in a2.  A negative value in the
+ *  range -4096 to -1 indicates a negated error code to be
+ *  reported in errno with a return value of -1, otherwise
+ *  the value in a2 is returned as is.

+ *  size is smaller than 32 bits.
+ *
+ *  Note:  XT2000 bus byte lanes are defined in terms of msbyte and lsbyte

+ *  sequences are not consistent between big and little endian processors.
+ *  This is fine for RAM, and for ROM if ROM is created for a specific
+ *  processor (and thus has correct byte sequences).  However this may be
+ *  unexpected for Flash, which might contain a file-system that one wants
+ *  to use for multiple processor configurations (eg. the Flash might contain
+ *  the Ethernet card's address, endianness-independent application data, etc).
+ *  That is, byte sequences written in Flash by a core of a given endianness
+ *  will be byte-swapped when seen by a core of the other endianness.
+ *  Someone implementing an endianness-independent Flash file system will
+ *  likely handle this byte-swapping issue in the Flash driver software.

+ * in-memory bitmap:
+ *
+ * Use 16 bit block counters to track pending writes to each "chunk".
+ * The 2 high order bits are special-purpose, the first is a flag indicating
+ * whether a resync is needed.  The second is a flag indicating whether a
+ * resync is active.
+ * This means that the counter is actually 14 bits:
+ *
+ * +--------+--------+------------------------------------------------+
+ * | resync | resync |               counter                          |
+ * | needed | active |                                                |
+ * |  (0-1) |  (0-1) |              (0-16383)                         |
+ * +--------+--------+------------------------------------------------+
+ *
+ * The "resync needed" bit is set when:
+ *    a '1' bit is read from storage at startup.
+ *    a write request fails on some drives
+ *    a resync is aborted on a chunk with 'resync active' set
+ * It is cleared (and resync-active set) when a resync starts across all drives
+ * of the chunk.
+ *
+ *
+ * The "resync active" bit is set when:
+ *    a resync is started on all drives, and resync_needed is set.
+ *       resync_needed will be cleared (as long as resync_active wasn't already set).
+ * It is cleared when a resync completes.
+ *
+ * The counter counts pending write requests, plus the on-disk bit.
+ * When the counter is '1' and the resync bits are clear, the on-disk
+ * bit can be cleared aswell, thus setting the counter to 0.
+ * When we set a bit, or in the counter (to start a write), if the fields is
+ * 0, we first set the disk bit and set the counter to 1.
+ *
+ * If the counter is 0, the on-disk bit is clear and the stipe is clean
+ * Anything that dirties the stipe pushes the counter to 2 (at least)
+ * and sets the on-disk bit (lazily).
+ * If a periodic sweep find the counter at 2, it is decremented to 1.
+ * If the sweep find the counter at 1, the on-disk bit is cleared and the
+ * counter goes to zero.
+ *
+ * Also, we'll hijack the "map" pointer itself and use it as two 16 bit block
+ * counters as a fallback when "page" memory cannot be allocated:
+ *
+ * Normal case (page memory allocated):
+ *
+ *     page pointer (32-bit)
+ *
+ *     [ ] ------+
+ *               |
+ *               +-------> [   ][   ]..[   ] (4096 byte page == 2048 counters)
+ *                          c1   c2    c2048
+ *
+ * Hijacked case (page memory allocation failed):
+ *
+ *     hijacked page pointer (32-bit)
+ *
+ *     [                  ][              ] (no page memory allocated)
