+/* I think it would be in everyone's best interest to follow this
+ * guidelines when writing PDC wrappers:
+ *
+ * - the name of the pdc wrapper should match one of the macros
+ * used for the first two arguments
+ * - don't use caps for random parts of the name
+ * - use the static PDC result buffers and "copyout" to structs
+ * supplied by the caller to encapsulate alignment restrictions
+ * - hold pdc_lock while in PDC or using static result buffers
+ * - use __pa() to convert virtual (kernel) pointers to physical
+ * ones.
+ * - the name of the struct used for pdc return values should equal
+ * one of the macros used for the first two arguments to the
+ * corresponding PDC call
+ * - keep the order of arguments
+ * - don't be smart (setting trailing NUL bytes for strings, return
+ * something useful even if the call failed) unless you are sure
+ * it's not going to affect functionality or performance
+ *
+ * Example:
+ * int pdc_cache_info(struct pdc_cache_info *cache_info )
+ * {
+ * int retval;
+ *
+ * spin_lock_irq(&pdc_lock);
+ * retval = mem_pdc_call(PDC_CACHE,PDC_CACHE_INFO,__pa(cache_info),0);
+ * convert_to_wide(pdc_result);
+ * memcpy(cache_info, pdc_result, sizeof(*cache_info));
+ * spin_unlock_irq(&pdc_lock);

+ * Notes:
+ * - PLT stub handling
+ * On 32bit (and sometimes 64bit) and with big kernel modules like xfs or
+ * ipv6 the relocation types R_PARISC_PCREL17F and R_PARISC_PCREL22F may
+ * fail to reach their PLT stub if we only create one big stub array for
+ * all sections at the beginning of the core or init section.
+ * Instead we now insert individual PLT stub entries directly in front of
+ * of the code sections where the stubs are actually called.
+ * This reduces the distance between the PCREL location and the stub entry
+ * so that the relocations can be fulfilled.
+ * While calculating the final layout of the kernel module in memory, the
+ * kernel module loader calls arch_mod_section_prepend() to request the
+ * to be reserved amount of memory in front of each individual section.
+ *
+ * - SEGREL32 handling
+ * We are not doing SEGREL32 handling correctly. According to the ABI, we
+ * should do a value offset, like this:
+ * if (in_init(me, (void *)val))
+ * val -= (uint32_t)me->init_layout.base;
+ * else
+ * val -= (uint32_t)me->core_layout.base;
+ * However, SEGREL32 is used only for PARISC unwind entries, and we want
+ * those entries to have an absolute address, and not just an offset.
+ *
+ * The unwind table mechanism has the ability to specify an offset for
+ * the unwind table; however, because we split off the init functions into
+ * a different piece of memory, it is not possible to do this using a
+ * single offset. Instead, we use the above hack for now.

+/*
+ * Edited comment from original sources:
+ *
+ * This driver programs the PCX-U/PCX-W performance counters
+ * on the PA-RISC 2.0 chips. The driver keeps all images now
+ * internally to the kernel to hopefully eliminate the possibility
+ * of a bad image halting the CPU. Also, there are different
+ * images for the PCX-W and later chips vs the PCX-U chips.
+ *
+ * Only 1 process is allowed to access the driver at any time,
+ * so the only protection that is needed is at open and close.
+ * A variable "perf_enabled" is used to hold the state of the
+ * driver. The spinlock "perf_lock" is used to protect the
+ * modification of the state during open/close operations so
+ * multiple processes don't get into the driver simultaneously.
+ *
+ * This driver accesses the processor directly vs going through
+ * the PDC INTRIGUE calls. This is done to eliminate bugs introduced
+ * in various PDC revisions. The code is much more maintainable
+ * and reliable this way vs having to debug on every version of PDC
+ * on every box.

+;* Name: perf_rdr_shift_in_W
+;*
+;* Description:
+;* This routine shifts data in from the RDR in arg0 and returns
+;* the result in ret0. If the RDR is <= 64 bits in length, it
+;* is shifted shifted backup immediately. This is to compensate
+;* for RDR10 which has bits that preclude PDC stack operations
+;* when they are in the wrong state.
+;*
+;* Arguments:
+;* arg0 : rdr to be read
+;* arg1 : bit length of rdr
+;*
+;* Returns:
+;* ret0 = next 64 bits of rdr data from staging register
+;*
+;* Register usage:
+;* arg0 : rdr to be read
+;* arg1 : bit length of rdr
+;* %r24 - original DR2 value
+;* %r1 - scratch
+;* %r29 - scratch
+;*
+;* Returns:
+;* ret0 = RDR data (right justified)

+ * ICORE_AV fires for every request which the Instruction Fetch Unit sends
+ * to the Runway Interface Block. Hence, this counts all I-misses, speculative
+ * or not, but does *not* include I-cache prefetches, which are generated by
+ * RIB.
+ * IRTN_AV fires twice for every I-cache miss returning from RIB to the IFU.
+ * It will not fire if a second I-cache miss is issued from the IFU to RIB
+ * before the first returns. Therefore, if the IRTN_AV count is much less
+ * than 2x the ICORE_AV count, many speculative I-cache misses are occurring
+ * which are "discovered" to be incorrect fairly quickly.
+ * The ratio of I-cache miss transactions on Runway to the ICORE_AV count is
+ * a measure of the effectiveness of instruction prefetching. This ratio
+ * should be between 1 and 2. If it is close to 1, most prefetches are
+ * eventually called for by the IFU; if it is close to 2, almost no prefetches
+ * are useful and they are wasted bus traffic.
+ *
+ * ctr0: counts ICORE_AV
+ * ctr1: counts IRTN_AV
+ * ctr2: counts all non-coherent READ transactions on Runway. (TTYPE D0)
+ * This should be just I-cache miss and I-prefetch transactions.
+ * ctr3: counts total processor cycles

+How does the Linux gateway page on PA-RISC work?
+------------------------------------------------
+The Linux gateway page on PA-RISC is "special".
+It actually has PAGE_GATEWAY bits set (this is linux terminology; in parisc
+terminology it's Execute, promote to PL0) in the page map. So anything
+executing on this page executes with kernel level privilege (there's more to it
+than that: to have this happen, you also have to use a branch with a ,gate
+completer to activate the privilege promotion). The upshot is that everything
+that runs on the gateway page runs at kernel privilege but with the current
+user process address space (although you have access to kernel space via %sr2).
+For the 0x100 syscall entry, we redo the space registers to point to the kernel
+address space (preserving the user address space in %sr3), move to wide mode if
+required, save the user registers and branch into the kernel syscall entry
+point. For all the other functions, we execute at kernel privilege but don't
+flip address spaces. The basic upshot of this is that these code snippets are
+executed atomically (because the kernel can't be pre-empted) and they may
+perform architecturally forbidden (to PL3) operations (like setting control
+registers).
