The settings in this register only control whether the + counters increment; their accessibility is not affected by the setting + of this register. + + When the CY, IR, or HPM__n__ bit in the `mcountinhibit` register is clear, + the `mcycle`, `minstret`, or `mhpmcountern` register increments as usual. + When the CY, IR, or HPM_n_ bit is set, the corresponding counter does + not increment. + + The `mcycle` CSR may be shared between harts on the same core, in which + case the `mcountinhibit.CY` field is also shared between those harts, + and so writes to `mcountinhibit.CY` will be visible to those harts. + + If the `mcountinhibit` register is not implemented, the implementation + behaves as though the register were set to zero. + + [NOTE] + ==== + When the `mcycle` and `minstret` counters are not needed, it is desirable + to conditionally inhibit them to reduce energy consumption. Providing a + single CSR to inhibit all counters also allows the counters to be + atomically sampled. + + Because the `mtime` counter can be shared between multiple cores, it + cannot be inhibited with the `mcountinhibit` mechanism. + ==== + +definedBy: + anyOf: + - name: Sm + - name: Smhpm +fields: + CY: + location: 0 + definedBy: Sm + description: When set, `mcycle.COUNT` stops counting in all privilege modes. + type(): | + return COUNTINHIBIT_EN[0] ?

Bits 15:0 are allocated to standard interrupt causes only, while + bits 16 and above are designated for platform use. + + NOTE: Interrupts designated for platform use may be designated for custom use + at the platform's discretion. + + An interrupt _i_ will trap to M-mode (causing the privilege mode to + change to M-mode) if all of the following are true: + + * either the current privilege mode is M and the MIE bit in the + `mstatus` register is set, or the current privilege mode has less + privilege than M-mode; + * bit _i_ is set in both `mip` and `mie`; + * if register `mideleg` exists, bit _i_ is not set in `mideleg`. + + These conditions for an interrupt trap to occur must be evaluated in a + bounded amount of time from when an interrupt becomes, or ceases to be, + pending in `mip`, and must also be evaluated immediately following the + execution of an __x__RET instruction or an explicit write to a CSR on + which these interrupt trap conditions expressly depend (including `mip`, + `mie`, `mstatus`, and `mideleg`). + + Interrupts to M-mode take priority over any interrupts to lower + privilege modes. + + A bit in `mie` must be writable if the corresponding interrupt can ever + become pending. Bits of `mie` that are not writable must be read-only + zero. + + [NOTE] + ==== + The machine-level interrupt registers handle a few root interrupt + sources which are assigned a fixed service priority for simplicity, + while separate external interrupt controllers can implement a more + complex prioritization scheme over a much larger set of interrupts that + are then muxed into the machine-level interrupt sources. + + ''' + + The non-maskable interrupt is not made visible via the `mip` register as + its presence is implicitly known when executing the NMI trap handler. + ==== + + If supervisor mode is implemented, bits `mip`.SEIP and `mie`.SEIE are + the interrupt-pending and interrupt-enable bits for supervisor-level + external interrupts. SEIP is writable in `mip`, and may be written by + M-mode software to indicate to S-mode that an external interrupt is + pending. Additionally, the platform-level interrupt controller may + generate supervisor-level external interrupts. Supervisor-level external + interrupts are made pending based on the logical-OR of the + software-writable SEIP bit and the signal from the external interrupt + controller. When `mip` is read with a CSR instruction, the value of the + SEIP bit returned in the `rd` destination register is the logical-OR of + the software-writable bit and the interrupt signal from the interrupt + controller, but the signal from the interrupt controller is not used to + calculate the value written to SEIP. Only the software-writable SEIP bit + participates in the read-modify-write sequence of a CSRRS or CSRRC + instruction. + + [NOTE] + ==== + For example, if we name the software-writable SEIP bit `B` and the + signal from the external interrupt controller `E`, then if + `csrrs t0, mip, t1` is executed, `t0[9]` is written with `B || E`, then + `B` is written with `B || t1[9]`.

The dynamic code executed between the LR and SC - instructions can only contain instructions from the base ''I'' - instruction set, excluding loads, stores, backward jumps, taken backward - branches, JALR, FENCE, and SYSTEM instructions.

The execution environment is responsible - for communicating which regions have this property. - * The SC must be to the same effective address and of the same data size - as the latest LR executed by the same hart. - - LR/SC sequences that do not lie within constrained LR/SC loops are - _unconstrained_. Unconstrained LR/SC sequences might succeed on some - attempts on some implementations, but might never succeed on other - implementations. - - [NOTE] - ==== - We restricted the length of LR/SC loops to fit within 64 contiguous - instruction bytes in the base ISA to avoid undue restrictions on - instruction cache and TLB size and associativity. Similarly, we - disallowed other loads and stores within the loops to avoid restrictions - on data-cache associativity in simple implementations that track the - reservation within a private cache. The restrictions on branches and - jumps limit the time that can be spent in the sequence. Floating-point - operations and integer multiply/divide were disallowed to simplify the - operating system's emulation of these instructions on implementations - lacking appropriate hardware support. - - Software is not forbidden from using unconstrained LR/SC sequences, but - portable software must detect the case that the sequence repeatedly - fails, then fall back to an alternate code sequence that does not rely - on an unconstrained LR/SC sequence. Implementations are permitted to - unconditionally fail any unconstrained LR/SC sequence. - ==== - - If a hart _H_ enters a constrained LR/SC loop, the execution environment - must guarantee that one of the following events eventually occurs: - - * _H_ or some other hart executes a successful SC to the reservation set - of the LR instruction in _H_'s constrained LR/SC loops. - * Some other hart executes an unconditional store or AMO instruction to - the reservation set of the LR instruction in _H_'s constrained LR/SC - loop, or some other device in the system writes to that reservation set. - * _H_ executes a branch or jump that exits the constrained LR/SC loop. - * _H_ traps. - - [NOTE] - ==== - Note that these definitions permit an implementation to fail an SC - instruction occasionally for any reason, provided the aforementioned - guarantee is not violated. - - As a consequence of the eventuality guarantee, if some harts in an - execution environment are executing constrained LR/SC loops, and no - other harts or devices in the execution environment execute an - unconditional store or AMO to that reservation set, then at least one - hart will eventually exit its constrained LR/SC loop. By contrast, if - other harts or devices continue to write to that reservation set, it is - not guaranteed that any hart will exit its LR/SC loop. - - Loads and load-reserved instructions do not by themselves impede the - progress of other harts' LR/SC sequences. We note this constraint - implies, among other things, that loads and load-reserved instructions - executed by other harts (possibly within the same core) cannot impede - LR/SC progress indefinitely. For example, cache evictions caused by - another hart sharing the cache cannot impede LR/SC progress - indefinitely. Typically, this implies reservations are tracked - independently of evictions from any shared cache. Similarly, cache - misses caused by speculative execution within a hart cannot impede LR/SC - progress indefinitely. - - These definitions admit the possibility that SC instructions may - spuriously fail for implementation reasons, provided progress is - eventually made. - - One advantage of CAS is that it guarantees that some hart eventually - makes progress, whereas an LR/SC atomic sequence could livelock - indefinitely on some systems. To avoid this concern, we added an - architectural guarantee of livelock freedom for certain LR/SC sequences. - - Earlier versions of this specification imposed a stronger - starvation-freedom guarantee. However, the weaker livelock-freedom - guarantee is sufficient to implement the C11 and C++11 languages, and is - substantially easier to provide in some microarchitectural styles. - ==== \ No newline at end of file +$schema: "ext_schema.json#" +kind: extension +name: Zalrsc +long_name: Atomic read-modify-write instructions +type: unprivileged +versions: +- version: "1.0.0" + state: ratified + ratification_date: 2024-04 +description: | + + Complex atomic memory operations on a single memory word or doubleword + are performed with the load-reserved (LR) and store-conditional (SC) + instructions. `LR.W` loads a word from the address in _rs1_, places the + sign-extended value in _rd_, and registers a _reservation set_--a set of + bytes that subsumes the bytes in the addressed word. `SC.W` conditionally + writes a word in _rs2_ to the address in _rs1_: the `SC.W` succeeds only + if the reservation is still valid and the reservation set contains the + bytes being written. If the `SC.W` succeeds, the instruction writes the + word in _rs2_ to memory, and it writes zero to _rd_. If the `SC.W` fails, + the instruction does not write to memory, and it writes a nonzero value + to _rd_. For the purposes of memory protection, a failed `SC.W` may be + treated like a store. Regardless of success or failure, executing an + `SC.W` instruction invalidates any reservation held by this hart. `LR.D` and + `SC.D` act analogously on doublewords and are only available on RV64. For + RV64, `LR.W` and `SC.W` sign-extend the value placed in _rd_. + + [NOTE] + ==== + Both compare-and-swap (CAS) and LR/SC can be used to build lock-free + data structures. After extensive discussion, we opted for LR/SC for + several reasons: 1) CAS suffers from the ABA problem, which LR/SC avoids + because it monitors all writes to the address rather than only checking + for changes in the data value; 2) CAS would also require a new integer + instruction format to support three source operands (address, compare + value, swap value) as well as a different memory system message format, + which would complicate microarchitectures; 3) Furthermore, to avoid the + ABA problem, other systems provide a double-wide CAS (DW-CAS) to allow a + counter to be tested and incremented along with a data word. This + requires reading five registers and writing two in one instruction, and + also a new larger memory system message type, further complicating + implementations; 4) LR/SC provides a more efficient implementation of + many primitives as it only requires one load as opposed to two with CAS + (one load before the CAS instruction to obtain a value for speculative + computation, then a second load as part of the CAS instruction to check + if value is unchanged before updating). + + The main disadvantage of LR/SC over CAS is livelock, which we avoid, + under certain circumstances, with an architected guarantee of eventual + forward progress as described below. Another concern is whether the + influence of the current x86 architecture, with its DW-CAS, will + complicate porting of synchronization libraries and other software that + assumes DW-CAS is the basic machine primitive. A possible mitigating + factor is the recent addition of transactional memory instructions to + x86, which might cause a move away from DW-CAS. + + More generally, a multi-word atomic primitive is desirable, but there is + still considerable debate about what form this should take, and + guaranteeing forward progress adds complexity to a system. + ==== + + [NOTE] + ==== + Note on the above note -- RISC-V now has CAS (Zacas)!! + ==== + + The failure code with value 1 encodes an unspecified failure. Other + failure codes are reserved at this time. Portable software should only + assume the failure code will be non-zero. + + [NOTE] + ==== + We reserve a failure code of 1 to mean ''unspecified'' so that simple + implementations may return this value using the existing mux required + for the `SLT`/`SLTU` instructions. More specific failure codes might be + defined in future versions or extensions to the ISA. + ==== + + For LR and SC, the `Zalrsc` extension requires that the address held in _rs1_ + be naturally aligned to the size of the operand (i.e., eight-byte + aligned for _doublewords_ and four-byte aligned for _words_). If the + address is not naturally aligned, an address-misaligned exception or an + access-fault exception will be generated. The access-fault exception can + be generated for a memory access that would otherwise be able to + complete except for the misalignment, if the misaligned access should + not be emulated. + [NOTE] + ==== + Emulating misaligned LR/SC sequences is impractical in most systems. + + Misaligned LR/SC sequences also raise the possibility of accessing + multiple reservation sets at once, which present definitions do not + provide for. + ==== + + An implementation can register an arbitrarily large reservation set on + each LR, provided the reservation set includes all bytes of the + addressed data word or doubleword. An SC can only pair with the most + recent LR in program order. An SC may succeed only if no store from + another hart to the reservation set can be observed to have occurred + between the LR and the SC, and if there is no other SC between the LR + and itself in program order. An SC may succeed only if no write from a + device other than a hart to the bytes accessed by the LR instruction can + be observed to have occurred between the LR and SC. Note this LR might + have had a different effective address and data size, but reserved the + SC's address as part of the reservation set. + + [NOTE] + ==== + Following this model, in systems with memory translation, an SC is + allowed to succeed if the earlier LR reserved the same location using an + alias with a different virtual address, but is also allowed to fail if + the virtual address is different. + + To accommodate legacy devices and buses, writes from devices other than + RISC-V harts are only required to invalidate reservations when they + overlap the bytes accessed by the LR. These writes are not required to + invalidate the reservation when they access other bytes in the + reservation set. + ==== + + The SC must fail if the address is not within the reservation set of the + most recent LR in program order. The SC must fail if a store to the + reservation set from another hart can be observed to occur between the + LR and SC. The SC must fail if a write from some other device to the + bytes accessed by the LR can be observed to occur between the LR and SC. + (If such a device writes the reservation set but does not write the + bytes accessed by the LR, the SC may or may not fail.)

A secret variable (arithmetically) - modifying any other variable/register turns that into a secret too. - If a secret ends up in address calculation affecting a load or store, that - is a violation. If a secret affects a branch's condition, that is also a - violation. A secret variable location or register becomes a non-secret via - specific zeroization/sanitisation or by being declared ciphertext - (or otherwise no-longer-secret information). In essence, secrets can only - "touch" instructions on the Zkt list while they are secrets. - - == Specific Instruction Rationale - - * HINT instruction forms (typically encodings with `rd=x0`) are excluded from - the data-independent time requirement. - * Floating point (F, D, Q, L extensions) are currently excluded from the - constant-time requirement as they have very few applications in standardised - cryptography. We may consider adding floating point add, sub, multiply as a - constant time requirement for some floating point extension in case a specific - algorithm (such as the PQC Signature algorithm Falcon) becomes critical. - * Cryptographers typically assume division to be variable-time (while - multiplication is constant time) and implement their Montgomery reduction - routines with that assumption. - * Zicsr, Zifencei are excluded. - * Some instructions are on the list simply because we see no harm in - including them in testing scope. - - == Programming Information - - For background information on secure programming "models", see: - - * Thomas Pornin: _"Why Constant-Time Crypto?"_ (A great introduction to timing assumptions.) https://www.bearssl.org/constanttime.html - * Jean-Philippe Aumasson: _"Guidelines for low-level cryptography software."_ - (A list of recommendations.) https://github.com/veorq/cryptocoding - * Peter Schwabe: _"Timing Attacks and Countermeasures."_ - (Lecture slides -- nice references.) - https://summerschool-croatia.cs.ru.nl/2016/slides/PeterSchwabe.pdf - * Adam Langley: _"ctgrind."_ (This is from 2010 but is still relevant.) - https://www.imperialviolet.org/2010/04/01/ctgrind.html - * Kris Kwiatkowski: _"Constant-time code verification with Memory Sanitizer."_ - https://www.amongbytes.com/post/20210709-testing-constant-time/ - * For early examples of timing attack vulnerabilities, see - https://www.kb.cert.org/vuls/id/997481 and related academic papers. - - == Zkt listings - - The following instructions are included in the `Zkt` subset - They are listed here grouped by their original parent extension. - - .Note to implementers - [NOTE, caption="SH"] - ==== - You do not need to implement all of these instructions to implement `Zkt`. - Rather, every one of these instructions that the core does implement must - adhere to the requirements of `Zkt`. - ==== - - === RVI (Base Instruction Set) - - Only basic arithmetic and `slt*` (for carry computations) are included. - The data-independent timing requirement does not apply to HINT instruction - encoding forms of these instructions. - - [%header,cols="^1,^1,4,8"] - |=== - |RV32 - |RV64 - |Mnemonic - |Instruction - - | ✓ | ✓ | lui _rd_, _imm_ | 'lui' - | ✓ | ✓ | auipc _rd_, _imm_ | 'auipc' - | ✓ | ✓ | addi _rd_, _rs1_, _imm_ | 'addi' - | ✓ | ✓ | slti _rd_, _rs1_, _imm_ | 'slti' - | ✓ | ✓ | sltiu _rd_, _rs1_, _imm_ | 'sltiu' - | ✓ | ✓ | xori _rd_, _rs1_, _imm_ | 'xori' - | ✓ | ✓ | ori _rd_, _rs1_, _imm_ | 'ori' - | ✓ | ✓ | andi _rd_, _rs1_, _imm_ | 'andi' - | ✓ | ✓ | slli _rd_, _rs1_, _imm_ | 'slli' - | ✓ | ✓ | srli _rd_, _rs1_, _imm_ | 'srli' - | ✓ | ✓ | srai _rd_, _rs1_, _imm_ | 'srai' - | ✓ | ✓ | add _rd_, _rs1_, _rs2_ | 'add' - | ✓ | ✓ | sub _rd_, _rs1_, _rs2_ | 'sub' - | ✓ | ✓ | sll _rd_, _rs1_, _rs2_ | 'sll' - | ✓ | ✓ | slt _rd_, _rs1_, _rs2_ | 'slt' - | ✓ | ✓ | sltu _rd_, _rs1_, _rs2_ | 'sltu' - | ✓ | ✓ | xor _rd_, _rs1_, _rs2_ | 'xor' - | ✓ | ✓ | srl _rd_, _rs1_, _rs2_ | 'srl' - | ✓ | ✓ | sra _rd_, _rs1_, _rs2_ | 'sra' - | ✓ | ✓ | or _rd_, _rs1_, _rs2_ | 'or' - | ✓ | ✓ | and _rd_, _rs1_, _rs2_ | 'and' - | | ✓ | addiw _rd_, _rs1_, _imm_ | 'addiw' - | | ✓ | slliw _rd_, _rs1_, _imm_ | 'slliw' - | | ✓ | srliw _rd_, _rs1_, _imm_ | 'srliw' - | | ✓ | sraiw _rd_, _rs1_, _imm_ | 'sraiw' - | | ✓ | addw _rd_, _rs1_, _rs2_ | 'addw' - | | ✓ | subw _rd_, _rs1_, _rs2_ | 'subw' - | | ✓ | sllw _rd_, _rs1_, _rs2_ | 'sllw' - | | ✓ | srlw _rd_, _rs1_, _rs2_ | 'srlw' - | | ✓ | sraw _rd_, _rs1_, _rs2_ | 'sraw' - |=== - - === RVM (Multiply) - - Multiplication is included; division and remaindering excluded. - - [%header,cols="^1,^1,4,8"] - |=== - |RV32 - |RV64 - |Mnemonic - |Instruction - - | ✓ | ✓ | mul _rd_, _rs1_, _rs2_ | 'mul' - | ✓ | ✓ | mulh _rd_, _rs1_, _rs2_ | 'mulh' - | ✓ | ✓ | mulhsu _rd_, _rs1_, _rs2_ | 'mulhsu' - | ✓ | ✓ | mulhu _rd_, _rs1_, _rs2_ | 'mulhu' - | | ✓ | mulw _rd_, _rs1_, _rs2_ | 'mulw' - |=== - - === RVC (Compressed) - - Same criteria as in RVI.
