+ * Design notes:
+ *
+ * 16 registers would be needed to hold the state matrix, but only 14 are
+ * available because 'sp' and 'pc' cannot be used. So we spill the elements
+ * (x8, x9) to the stack and swap them out with (x10, x11). This adds one
+ * 'ldrd' and one 'strd' instruction per round.
+ *
+ * All rotates are performed using the implicit rotate operand accepted by the
+ * 'add' and 'eor' instructions. This is faster than using explicit rotate
+ * instructions. To make this work, we allow the values in the second and last
+ * rows of the ChaCha state matrix (rows 'b' and 'd') to temporarily have the
+ * wrong rotation amount. The rotation amount is then fixed up just in time
+ * when the values are used. 'brot' is the number of bits the values in row 'b'
+ * need to be rotated right to arrive at the correct values, and 'drot'
+ * similarly for row 'd'. (brot, drot) start out as (0, 0) but we make it such
+ * that they end up as (25, 24) after every round.

+ @ Trivia.
+ @
+ @ Result of multiplication of n-bit number by m-bit number is
+ @ n+m bits wide. However! Even though 2^n is a n+1-bit number,
+ @ m-bit number multiplied by 2^n is still n+m bits wide.
+ @
+ @ Sum of two n-bit numbers is n+1 bits wide, sum of three - n+2,
+ @ and so is sum of four. Sum of 2^m n-m-bit numbers and n-bit
+ @ one is n+1 bits wide.
+ @
+ @ >>+ denotes Hnext += Hn>>26, Hn &= 0x3ffffff. This means that
+ @ H0, H2, H3 are guaranteed to be 26 bits wide, while H1 and H4
+ @ can be 27. However! In cases when their width exceeds 26 bits
+ @ they are limited by 2^26+2^6. This in turn means that *sum*
+ @ of the products with these values can still be viewed as sum
+ @ of 52-bit numbers as long as the amount of addends is not a
+ @ power of 2. For example,
+ @
+ @ H4 = H4*R0 + H3*R1 + H2*R2 + H1*R3 + H0 * R4,
+ @
+ @ which can't be larger than 5 * (2^26 + 2^6) * (2^26 + 2^6), or
+ @ 5 * (2^52 + 2*2^32 + 2^12), which in turn is smaller than
+ @ 8 * (2^52) or 2^55. However, the value is then multiplied by
+ @ by 5, so we should be looking at 5 * 5 * (2^52 + 2^33 + 2^12),
+ @ which is less than 32 * (2^52) or 2^57. And when processing
+ @ data we are looking at triple as many addends...
+ @
+ @ In key setup procedure pre-reduced H0 is limited by 5*4+1 and
+ @ 5*H4 - by 5*5 52-bit addends, or 57 bits. But when hashing the
+ @ input H0 is limited by (5*4+1)*3 addends, or 58 bits, while
+ @ 5*H4 by 5*5*3, or 59[!] bits. How is this relevant? vmlal.u32
+ @ instruction accepts 2x32-bit input and writes 2x64-bit result.
+ @ This means that result of reduction have to be compressed upon
+ @ loop wrap-around. This can be done in the process of reduction
+ @ to minimize amount of instructions [as well as amount of
+ @ 128-bit instructions, which benefits low-end processors], but
+ @ one has to watch for H2 (which is narrower than H0) and 5*H4
+ @ not being wider than 58 bits, so that result of right shift
+ @ by 26 bits fits in 32 bits. This is also useful on x86,
+ @ because it allows to use paddd in place for paddq, which
+ @ benefits Atom, where paddq is ridiculously slow.

+ @
+ @ Trivia.
+ @
+ @ Result of multiplication of n-bit number by m-bit number is
+ @ n+m bits wide. However! Even though 2^n is a n+1-bit number,
+ @ m-bit number multiplied by 2^n is still n+m bits wide.
+ @
+ @ Sum of two n-bit numbers is n+1 bits wide, sum of three - n+2,
+ @ and so is sum of four. Sum of 2^m n-m-bit numbers and n-bit
+ @ one is n+1 bits wide.
+ @
+ @ >>+ denotes Hnext += Hn>>26, Hn &= 0x3ffffff. This means that
+ @ H0, H2, H3 are guaranteed to be 26 bits wide, while H1 and H4
+ @ can be 27. However! In cases when their width exceeds 26 bits
+ @ they are limited by 2^26+2^6. This in turn means that *sum*
+ @ of the products with these values can still be viewed as sum
+ @ of 52-bit numbers as long as the amount of addends is not a
+ @ power of 2. For example,
+ @
+ @ H4 = H4*R0 + H3*R1 + H2*R2 + H1*R3 + H0 * R4,
+ @
+ @ which can't be larger than 5 * (2^26 + 2^6) * (2^26 + 2^6), or
+ @ 5 * (2^52 + 2*2^32 + 2^12), which in turn is smaller than
+ @ 8 * (2^52) or 2^55. However, the value is then multiplied by
+ @ by 5, so we should be looking at 5 * 5 * (2^52 + 2^33 + 2^12),
+ @ which is less than 32 * (2^52) or 2^57. And when processing
+ @ data we are looking at triple as many addends...
+ @
+ @ In key setup procedure pre-reduced H0 is limited by 5*4+1 and
+ @ 5*H4 - by 5*5 52-bit addends, or 57 bits. But when hashing the
+ @ input H0 is limited by (5*4+1)*3 addends, or 58 bits, while
+ @ 5*H4 by 5*5*3, or 59[!] bits. How is this relevant? vmlal.u32
+ @ instruction accepts 2x32-bit input and writes 2x64-bit result.
+ @ This means that result of reduction have to be compressed upon
+ @ loop wrap-around. This can be done in the process of reduction
+ @ to minimize amount of instructions [as well as amount of
+ @ 128-bit instructions, which benefits low-end processors], but
+ @ one has to watch for H2 (which is narrower than H0) and 5*H4
+ @ not being wider than 58 bits, so that result of right shift
+ @ by 26 bits fits in 32 bits. This is also useful on x86,
+ @ because it allows to use paddd in place for paddq, which
+ @ benefits Atom, where paddq is ridiculously slow.

+ * frame's lr as the current frame's lr, but we can't trace the most recent
+ * call. Inserting a false stack frame allows us to reference the function
+ * called last in the stacktrace.
+ *
+ * If the call instruction was a bl we can look at the callers branch
+ * instruction to calculate the saved pc. We can recover the pc in most cases,
+ * but in cases such as calling function pointers we cannot. In this case,
+ * default to using the lr. This will be some address in the function, but will
+ * not be the function start.
+ *
+ * Unfortunately due to the stack frame layout we can't dump r0 - r3, but these
+ * are less frequently saved.
+ *
+ * Stack frame layout:
+ * <larger addresses>
+ * saved lr
+ * frame=> saved fp
+ * optionally saved caller registers (r4 - r10)
+ * optionally saved arguments (r0 - r3)
+ * <top of stack frame>
+ * <smaller addresses>
+ *
+ * Functions start with the following code sequence:
+ * corrected pc => stmfd sp!, {..., fp, lr}
+ * add fp, sp, #x
+ * stmfd sp!, {r0 - r3} (optional)
+ *
+ *
+ *
+ *
+ *
+ *
+ * The diagram below shows an example stack setup for dump_stack.
+ *
+ * The frame for c_backtrace has pointers to the code of dump_stack. This is
+ * why the frame of c_backtrace is used to for the pc calculation of
+ * dump_stack. This is why we must move back a frame to print dump_stack.
+ *
+ * The stored locals for dump_stack are in dump_stack's frame. This means that
+ * to fully print dump_stack's frame we need both the frame for dump_stack (for
+ * locals) and the frame that was called by dump_stack (for pc).
+ *
+ * To print locals we must know where the function start is. If we read the
+ * function prologue opcodes we can determine which variables are stored in the
+ * stack frame.
+ *
+ * To find the function start of dump_stack we can look at the stored LR of
+ * show_stack. It points at the instruction directly after the bl dump_stack.
+ * We can then read the offset from the bl opcode to determine where the branch
+ * takes us. The address calculated must be the start of dump_stack.

* AArch64 UP and SMP safe atomic ops. We use load exclusive and
* store exclusive to ensure that these are atomic. We may loop
* to ensure that the update happens.
- *
- * NOTE: these functions do *not* follow the PCS and must explicitly
- * save any clobbered registers other than x0 (regardless of return
- * value). This is achieved through -fcall-saved-* compiler flags for
- * this file, which unfortunately don't work on a per-function basis
- * (the optimize attribute silently ignores these options).

+ * [ AAAAAAAA BBBBBBB1 BBBBBBB1 ... AAAAAAAA BBBBBB1 ... ]
+ *
+ * i.e. start with an address, followed by any number of bitmaps. The

+ * the last address entry.
+ *
+ * The bitmap entries must have 1 in the least significant bit. The
+ * assumption here is that an address cannot have 1 in lsb. Odd
+ * addresses are not supported. Any odd addresses are stored in the RELA
+ * section, which is handled above.
+ *
+ * Excluding the least significant bit in the bitmap, each non-zero
+ * bit in the bitmap represents a relocation to be applied to
+ * a corresponding machine word that follows the base address
+ * word. The second least significant bit represents the machine
+ * word immediately following the initial address, and each bit
+ * that follows represents the next word, in linear order. As such,
+ * a single bitmap can encode up to 63 relocations in a 64-bit object.

- * 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#
- * |
- * | 0 1 2 3
- * ----------|---------------------------------------
- * config | 0x21000 0x22000 0x23000 0x24000
- * |
- * even rrb | 0[0] n/a 1[0] n/a [] == implied even/odd

- * Description: This register's value is a bit vector that guards *

- * 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 *

- * Crosstalk credits which are used outbound to Crosstalk. An *
- * internal counter called the Crosstalk Credit Timeout Counter *
- * increments every 128 II clocks. The counter starts counting *
- * anytime the credit count drops below a threshold, and resets to *
- * zero (stops counting) anytime the credit count is at or above the *
- * threshold. The threshold is 1 credit in direct connect mode and 2 *
- * in Crossbow connect mode. When the internal Crosstalk Credit *
- * Timeout Counter reaches the value programmed in this register, a *
- * Crosstalk Credit Timeout has occurred. The internal counter is not *
- * readable from software, and stops counting at its maximum value, *
- * so it cannot cause more than one interrupt. *

- * Description: This register specifies the timeout value to use for *

- * TAIL_TO field. An internal counter associated with this register *
- * is incremented every 128 II internal clocks (7 bits). The counter *
- * starts counting anytime a header micropacket is received and stops *
- * counting (and resets to zero) any time a micropacket with a Tail *
- * bit is received. Once the counter reaches the threshold value *
- * programmed in this register, it generates an interrupt to the *
- * processor that is programmed into the IIDSR. The counter saturates *
- * (does not roll over) at its maximum value, so it cannot cause *
- * another interrupt until after it is cleared. *
- * 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 *
- * have their Read Response timers bumped. Whenever any of them match *
- * the value in the RRSP_TO field, a Read Response Timeout has *

- * 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.
- *
- *
- * The macros convert between cpu physical ids & slice/nasid/cnodeid.
- * These terms are described below:
- *
- *
- * Brick
- * ----- ----- ----- ----- CPU
- * | 0 | | 1 | | 0 | | 1 | SLICE
- * ----- ----- ----- -----

-/*
- * 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.

- * IO error structure.
- *
- * This structure would expand to hold the information retrieved from
- * all IO related error registers.
- *
- * This structure is defined to hold all system specific
- * information related to a single error.
- *
- * This serves a couple of purpose.
- * - Error handling often involves translating one form of address to other
- * form. So, instead of having different data structures at each level,
- * we have a single structure, and the appropriate fields get filled in
- * at each layer.
- * - This provides a way to dump all error related information in any layer
- * of erorr handling (debugging aid).
- *

- * DMA MANAGEMENT
- *
- * The Bridge ASIC provides three methods of doing DMA: via a "direct map"
- * register available in 32-bit PCI space (which selects a contiguous 2G
- * address space on some other widget), via "direct" addressing via 64-bit
- * PCI space (all destination information comes from the PCI address,
- * including transfer attributes), and via a "mapped" region that allows
- * a bunch of different small mappings to be established with the PMU.
- *
- * For efficiency, we most prefer to use the 32bit direct mapping facility,
- * since it requires no resource allocations. The advantage of using the
- * PMU over the 64-bit direct is that single-cycle PCI addressing can be
- * used; the advantage of using 64-bit direct over PMU addressing is that
- * we do not have to allocate entries in the PMU.

- * if(mmr address < 0x45000) {
- * if(mmr address == 0 or 0x80)
- * mmr wrt or read address 0xc0

- *
- * if(mmr address == 0x100)
- * mmr wrt or read address 0x38
- * mmr wrt or read address 0xb050
- * } else
- * do desired mmr access
- *
- * According to hw, we can use reads instead of writes to the above address

+# There is a number of MIPS ABI in use, O32 and N32/64 are most
+# widely used. Then there is a new contender: NUBI. It appears that if
+# one picks the latter, it's possible to arrange code in ABI neutral
+# manner. Therefore let's stick to NUBI register layout:
+#
+($zero,$at,$t0,$t1,$t2)=map("\$$_",(0..2,24,25));
+($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
+($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7,$s8,$s9,$s10,$s11)=map("\$$_",(12..23));
+($gp,$tp,$sp,$fp,$ra)=map("\$$_",(3,28..31));
+#
+# The return value is placed in $a0. Following coding rules facilitate
+# interoperability:
+#
+# - never ever touch $tp, "thread pointer", former $gp [o32 can be
+# excluded from the rule, because it's specified volatile];
+# - copy return value to $t0, former $v0 [or to $a0 if you're adapting
+# old code];
+# - on O32 populate $a4-$a7 with 'lw $aN,4*N($sp)' if necessary;
+#
+# For reference here is register layout for N32/64 MIPS ABIs:
+#
+# ($zero,$at,$v0,$v1)=map("\$$_",(0..3));
+# ($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
+# ($t0,$t1,$t2,$t3,$t8,$t9)=map("\$$_",(12..15,24,25));
+# ($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7)=map("\$$_",(16..23));

- * respect to any other processor or coherent I/O module.

- * - The barrier does not guarantee the order in which instruction fetches are

- * - A stype value of zero will always be defined such that it performs the most
- * complete set of synchronization operations that are defined.This means
- * stype zero always does a completion barrier that affects both loads and
- * stores preceding the SYNC instruction and both loads and stores that are
- * subsequent to the SYNC instruction. Non-zero values of stype may be defined
- * by the architecture or specific implementations to perform synchronization

- * act the same as stype zero completion barrier. This allows software written
- * for an implementation with a lighter-weight barrier to work on another
- * implementation which only implements the stype zero completion barrier.
- *
- * - A completion barrier is required, potentially in conjunction with SSNOP (in
- * Release 1 of the Architecture) or EHB (in Release 2 of the Architecture),
- * to guarantee that memory reference results are visible across operating

- * Some Loongson 3 CPUs have a bug wherein execution of a memory access (load,
- * store or pref) in between an ll & sc can cause the sc instruction to
- * erroneously succeed, breaking atomicity. Whilst it's unusual to write code
- * containing such sequences, this bug bites harder than we might otherwise
- * expect due to reordering & speculation:
- *
- * 1) A memory access appearing prior to the ll in program order may actually
- * be executed after the ll - this is the reordering case.
- *
- * In order to avoid this we need to place a memory barrier (ie. a sync
- * instruction) prior to every ll instruction, in between it & any earlier
- * memory access instructions. Many of these cases are already covered by
- * smp_mb__before_llsc() but for the remaining cases, typically ones in
- * which multiple CPUs may operate on a memory location but ordering is not
- * usually guaranteed, we use loongson_llsc_mb() below.
- *
- * This reordering case is fixed by 3A R2 CPUs, ie. 3A2000 models and later.
- *
- * 2) If a conditional branch exists between an ll & sc with a target outside
- * of the ll-sc loop, for example an exit upon value mismatch in cmpxchg()
- * or similar, then misprediction of the branch may allow speculative
- * execution of memory accesses from outside of the ll-sc loop.
- *
- * In order to avoid this we need a memory barrier (ie. a sync instruction)
- * at each affected branch target, for which we also use loongson_llsc_mb()
- * defined below.
- *
- * This case affects all current Loongson 3 CPUs.
+ * In the Loongson3 LL/SC workaround case, all of our LL/SC loops already have
+ * a completion barrier immediately preceding the LL instruction. Therefore we
+ * can skip emitting a barrier from __smp_mb__before_atomic().

+ * We use the same huge page sizes as 64-bit MIPS. Assuming a 4KB page size,

+ * 4MB virtual address region (pointing to a 4KB PTE page of 1,024 32-bit pte_t

+ * spanning both halves of a TLB EntryLo0,1 pair, requires 2MB hardware page
+ * support, not one of the standard supported sizes (1MB,4MB,16MB,...).
+ * To correct for this, when huge pages are enabled, we halve the number of
+ * pointers a PTE page holds, making its last half go to waste. Correspondingly,
+ * we double the number of PGD pages. Overall, page table memory overhead
+ * increases to match 64-bit MIPS, but PTE lookups remain CPU cache-friendly.

+ * HEART is the main system controller ASIC for IP30 system. It incorporates
+ * a memory controller, interrupt status/cause/set/clear management, basic
+ * timer with count/compare, and other functionality. For Linux, not all of
+ * HEART's functions are fully understood.
+ *
+ * Implementation note: All HEART registers are 64bits-wide, but the mem_cfg
+ * register only reports correct values if queried in 32bits. Hence the need
+ * for a union. Even though mem_cfg.l has 8 array slots, we only ever query
+ * up to 4 of those. IP30 has 8 DIMM slots arranged into 4 banks, w/ 2 DIMMs
+ * per bank. Each 32bit read accesses one of these banks. Perhaps HEART was
+ * designed to address up to 8 banks (16 DIMMs)? We may never know.

+ *
+ * b) Multiple variants of ordering barrier are provided which allow the
+ * effects to be restricted to different combinations of older or younger

- * Following are the BOOK3S exception handler helper macros.

- *
- * EXC_REAL_* - real, unrelocated exception vectors
- * EXC_VIRT_* - virt (AIL), unrelocated exception vectors
- * TRAMP_REAL_* - real, unrelocated helpers (virt can call these)
- * TRAMP_VIRT_* - virt, unreloc helpers (in practice, real can use)
- * TRAMP_KVM - KVM handlers that get put into real, unrelocated
- * EXC_COMMON - virt, relocated common handlers
- *
- * The EXC handlers are given a name, and branch to name_common, or the
- * appropriate KVM or masking function. Vector handler verieties are as
- * follows:
- *
- * EXC_{REAL|VIRT}_BEGIN/END - used to open-code the exception
- *
- * EXC_{REAL|VIRT} - standard exception
- *
- * EXC_{REAL|VIRT}_suffix
- * where _suffix is:
- * - _MASKABLE - maskable exception
- * - _OOL - out of line with trampoline to common handler
- * - _HV - HV exception
- *
- * There can be combinations, e.g., EXC_VIRT_OOL_MASKABLE_HV
- *
- * KVM handlers come in the following verieties:
- * TRAMP_KVM
- * TRAMP_KVM_SKIP
- * TRAMP_KVM_HV
- * TRAMP_KVM_HV_SKIP
- *
- * COMMON handlers come in the following verieties:
- * EXC_COMMON_BEGIN/END - used to open-code the handler
- * EXC_COMMON
- * EXC_COMMON_ASYNC
- *
- * TRAMP_REAL and TRAMP_VIRT can be used with BEGIN/END. KVM
- * and OOL handlers are implemented as types of TRAMP and TRAMP_VIRT handlers.

+ * A pseries guest can be run as secure guest on Ultravisor-enabled

+ *
+ * The page-in or page-out requests from UV will come to HV as hcalls and
+ * HV will call back into UV via ultracalls to satisfy these page requests.
+ *
+ * Private ZONE_DEVICE memory equal to the amount of secure memory
+ * available in the platform for running secure guests is hotplugged.
+ * Whenever a page belonging to the guest becomes secure, a page from this
+ * private device memory is used to represent and track that secure page
+ * on the HV side. Some pages (like virtio buffers, VPA pages etc) are
+ * shared between UV and HV. However such pages aren't represented by
+ * device private memory and mappings to shared memory exist in both
+ * UV and HV page tables.
+ */
+
+/*
+ * Notes on locking
+ *
+ * kvm->arch.uvmem_lock is a per-guest lock that prevents concurrent
+ * page-in and page-out requests for the same GPA. Concurrent accesses
+ * can either come via UV (guest vCPUs requesting for same page)
+ * or when HV and guest simultaneously access the same page.
+ * This mutex serializes the migration of page from HV(normal) to
+ * UV(secure) and vice versa. So the serialization points are around
+ * migrate_vma routines and page-in/out routines.
+ *
+ * Per-guest mutex comes with a cost though. Mainly it serializes the
+ * fault path as page-out can occur when HV faults on accessing secure
+ * guest pages. Currently UV issues page-in requests for all the guest
+ * PFNs one at a time during early boot (UV_ESM uvcall), so this is
+ * not a cause for concern. Also currently the number of page-outs caused
+ * by HV touching secure pages is very very low. If an when UV supports
+ * overcommitting, then we might see concurrent guest driven page-outs.
+ *
+ * Locking order
+ *
+ * 1. kvm->srcu - Protects KVM memslots
+ * 2. kvm->mm->mmap_sem - find_vma, migrate_vma_pages and helpers, ksm_madvise
+ * 3. kvm->arch.uvmem_lock - protects read/writes to uvmem slots thus acting
+ * as sync-points for page-in/out
+ */
+
+/*
+ * Notes on page size
+ *
+ * Currently UV uses 2MB mappings internally, but will issue H_SVM_PAGE_IN
+ * and H_SVM_PAGE_OUT hcalls in PAGE_SIZE(64K) granularity. HV tracks
+ * secure GPAs at 64K page size and maintains one device PFN for each
+ * 64K secure GPA. UV_PAGE_IN and UV_PAGE_OUT calls by HV are also issued
+ * for 64K page at a time.
+ *
+ * HV faulting on secure pages: When HV touches any secure page, it
+ * faults and issues a UV_PAGE_OUT request with 64K page size. Currently
+ * UV splits and remaps the 2MB page if necessary and copies out the
+ * required 64K page contents.
+ *
+ * Shared pages: Whenever guest shares a secure page, UV will split and
+ * remap the 2MB page if required and issue H_SVM_PAGE_IN with 64K page size.
+ *
+ * HV invalidating a page: When a regular page belonging to secure
+ * guest gets unmapped, HV informs UV with UV_PAGE_INVAL of 64K
+ * page size. Using 64K page size is correct here because any non-secure
+ * page will essentially be of 64K page size. Splitting by UV during sharing
+ * and page-out ensures this.
+ *
+ * Page fault handling: When HV handles page fault of a page belonging
+ * to secure guest, it sends that to UV with a 64K UV_PAGE_IN request.
+ * Using 64K size is correct here too as UV would have split the 2MB page
+ * into 64k mappings and would have done page-outs earlier.
+ *
+ * In summary, the current secure pages handling code in HV assumes
+ * 64K page size and in fact fails any page-in/page-out requests of
+ * non-64K size upfront. If and when UV starts supporting multiple
+ * page-sizes, we need to break this assumption.

+ This kernel feature is useful for number crunching applications
+ that may need to compute untrusted bytecode during their
+ execution. By using pipes or other transports made available to
+ the process as file descriptors supporting the read/write
+ syscalls, it's possible to isolate those applications in
+ their own address space using seccomp. Once seccomp is
+ enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
+ and the task is only allowed to execute a few safe syscalls
+ defined by each seccomp mode.

+ * This is a bit tricky, see also the comment with setup_physmem().
+ *
+ * Essentially, setup_physmem() uses a file to mmap() our physmem,
+ * but the code and data we *already* have is omitted. To us, this
+ * is no difference, since they both become part of our address
+ * space and memory consumption. To somebody looking in from the
+ * outside, however, it is different because the part of our memory
+ * consumption that's already part of the binary (code/data) is not
+ * mapped from the file, so it's not visible to another mmap from
+ * the file descriptor.
+ *
+ * Thus, don't advertise this space to the vhost-user slave. This
+ * means that the slave will likely abort or similar when we give
+ * it an address from the hidden range, since it's not marked as
+ * a valid address, but at least that way we detect the issue and
+ * don't just have the slave read an all-zeroes buffer from the
+ * shared memory file, or write something there that we can never
+ * see (depending on the direction of the virtqueue traffic.)
+ *
+ * Since we usually don't want to use .text for virtio buffers,
+ * this effectively means that you cannot use
+ * 1) global variables, which are in the .bss and not in the shm
+ * file-backed memory
+ * 2) the stack in some processes, depending on where they have
+ * their stack (or maybe only no interrupt stack?)
+ *
+ * The stack is already not typically valid for DMA, so this isn't
+ * much of a restriction, but global variables might be encountered.
+ *
+ * It might be possible to fix it by copying around the data that's
+ * between bss_start and where we map the file now, but it's not
+ * something that you typically encounter with virtio drivers, so
+ * it didn't seem worthwhile.

+# This module implements Poly1305 hash for x86_64.
+#
+# March 2015
+#
+# Initial release.
+#
+# December 2016
+#
+# Add AVX512F+VL+BW code path.
+#
+# November 2017
+#
+# Convert AVX512F+VL+BW code path to pure AVX512F, so that it can be
+# executed even on Knights Landing. Trigger for modification was
+# observation that AVX512 code paths can negatively affect overall
+# Skylake-X system performance. Since we are likely to suppress
+# AVX512F capability flag [at least on Skylake-X], conversion serves
+# as kind of "investment protection". Note that next *lake processor,
+# Cannonlake, has AVX512IFMA code path to execute...
+#
+# Numbers are cycles per processed byte with poly1305_blocks alone,
+# measured with rdtsc at fixed clock frequency.

+# it was faster than integer-only code only on older Intel P4 and

- * Handle caching attributes in page tables (PAT)
+ * Page Attribute Table (PAT) support: handle memory caching attributes in page tables.
*
* Authors: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com>
* Suresh B Siddha <suresh.b.siddha@intel.com>
*
* Loosely based on earlier PAT patchset from Eric Biederman and Andi Kleen.
+ *
+ * Basic principles:
+ *
+ * PAT is a CPU feature supported by all modern x86 CPUs, to allow the firmware and
+ * the kernel to set one of a handful of 'caching type' attributes for physical
+ * memory ranges: uncached, write-combining, write-through, write-protected,
+ * and the most commonly used and default attribute: write-back caching.
+ *
+ * PAT support supercedes and augments MTRR support in a compatible fashion: MTRR is
+ * a hardware interface to enumerate a limited number of physical memory ranges
+ * and set their caching attributes explicitly, programmed into the CPU via MSRs.
+ * Even modern CPUs have MTRRs enabled - but these are typically not touched
+ * by the kernel or by user-space (such as the X server), we rely on PAT for any
+ * additional cache attribute logic.
+ *
+ * PAT doesn't work via explicit memory ranges, but uses page table entries to add
+ * cache attribute information to the mapped memory range: there's 3 bits used,
+ * (_PAGE_PWT, _PAGE_PCD, _PAGE_PAT), with the 8 possible values mapped by the
+ * CPU to actual cache attributes via an MSR loaded into the CPU (MSR_IA32_CR_PAT).
+ *
+ * ( There's a metric ton of finer details, such as compatibility with CPU quirks
+ * that only support 4 types of PAT entries, and interaction with MTRRs, see
+ * below for details. )
