2024-07-11RISC-V: Add platform property/capability extensionsTsukasa OI1-0/+33
RISC-V Profiles document defines number of "extensions" that indicate certain platform properties/capabilities just like 'Zkt' extension from the RISC-V cryptography extensions. This commit defines 20 platform property/capability extensions as defined in the RISC-V Profiles documentation. The only exception: 'Ssstateen' extension is defined separately because it defines a subset (supervisor/hypervisor view) of the 'Smstateen' extension. This is based on the ratified version of RISC-V Profiles: <https://github.com/riscv/riscv-profiles/releases/tag/v1.0> [Definition] "Main memory regions": Main memory regions (in contrast to I/O or vacant memory regions) with both the cacheability and coherence PMAs. [New Unprivileged Extensions] 1. 'Ziccif' "Main memory regions" support instruction fetch and any instruction fetches of naturally aligned power-of-2 sizes up to min(ILEN, XLEN) are atomic. 2. 'Ziccrse' "Main memory regions" provide the eventual success guarantee for LR/SC sequence (RsrvEventual). 3. 'Ziccamoa' "Main memory regions" support all currently-defined AMO operations including swap, logical and arithmetic operations (AMOArithmetic). 4. 'Za64rs' For LR/SC instructions, reservation sets are contiguous, naturally aligned and at most 64-bytes in size. 5. 'Za128rs' Likewise, but reservation sets are at most 128-bytes in size. 6. 'Zicclsm' Misaligned loads / stores to "main memory regions" are supported. Those include both regular scalar and vector accesses but does not include AMOs and other specialized forms of memory accesses. 7. 'Zic64b' Cache blocks are (exactly) 64-bytes in size and naturally aligned. [New Privileged Extensions] 1. 'Svbare' "satp" mode Bare is supported. 2. 'Svade' Page-fault exceptions are raised when a page is accessed when A bit is clear, or written when D bit is clear. 3. 'Ssccptr' "Main memory regions" support hardware page-table reads. 4. 'Sstvecd' "stvec" mode Direct is supported. When "stvec" mode is Direct, "stvec.BASE" is capable of holding any valid 4-byte aligned address. 5. 'Sstvala' "stval" is always written with a nonzero value whenever possible as specified in the Privileged Architecture documentation (version 20211203: see section 4.1.9). 6. 'Sscounterenw' For any "hpmcounter" that is not read-only zero, the corresponding bit in "scounteren" is writable. 7. 'Ssu64xl' "sstatus.UXL" is capable of holding the value 0b10 (UXLEN==64 is supported). 8. 'Shcounterenw' Similar to 'Sscounterenw' but the same rule applies to "hcounteren". 9. 'Shvstvala' Similar to 'Sstvala' but the same rule applies to "vstval". 10. 'Shtvala' "htval" is written with the faulting guest physical address as long as permitted by the ISA (a bit similar to 'Sstvala' and 'Shvstvala'). 11. 'Shvstvecd' Similar to 'Sstvecd' but the same rule applies to "vstvec". 12. 'Shvsatpa' All translation modes supported in "satp" are also supported in "vsatp". 13. 'Shgatpa' For each supported virtual memory scheme SvNN supported in "satp", the corresponding "hgatp" SvNNx4 mode is supported. The "hgatp" mode Bare is also supported. [Implications] (Due to reservation set size constraints) - 'Za64rs' -> 'Za128rs' (Due to the fact that a privileged "extension" directly refers a CSR) - 'Svbare' -> 'Zicsr' - 'Sstvecd' -> 'Zicsr' - 'Sstvala' -> 'Zicsr' - 'Sscounterenw' -> 'Zicsr' - 'Ssu64xl' -> 'Zicsr' (Due to the fact that a privileged "extension" indirectly depends on CSRs) - 'Svade' -> 'Zicsr' (Due to the fact that a privileged "extension" is a hypervisor property) - 'Shcounterenw' -> 'H' - 'Shvstvala' -> 'H' - 'Shtvala' -> 'H' - 'Shvstvecd' -> 'H' - 'Shvsatpa' -> 'H' - 'Shgatpa' -> 'H' bfd/ * elfxx-riscv.c (riscv_implicit_subsets): Updated for property and capability extensions.

2023-12-01RISC-V: Zv*: Add support for Zvkb ISA extensionChristoph Müllner1-2/+8
Back then when the support for the RISC-V vector crypto extensions was merged, the specification was frozen, but not ratified. A frozen specification is allowed to change within tight bounds before ratification and this has happend with the vector crypto extensions. The following changes were applied: * A new extension Zvkb was defined, which is a strict subset of Zvbb. * Zvkn and Zvks include now Zvkb instead of Zvbb. This patch implements these changes between the frozen and the ratified specification. Note, that this technically an incompatible change of Zvkn and Zvks, but I am not aware of any project that depends on the currently implemented behaviour of Zvkn and Zvks. So this patch should be fine. Reported-By: Jerry Shih <jerry.shih@sifive.com> Reported-By: Eric Biggers <ebiggers@kernel.org> Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu>

T-Head has a range of vendor-specific instructions. Therefore it makes sense to group them into smaller chunks in form of vendor extensions.

2023-11-23RISC-V: Add T-Head VECTOR vendor extension.Jin Ma1-0/+12
T-Head has a range of vendor-specific instructions ([2]). Therefore it makes sense to group them into smaller chunks in form of vendor extensions. This patch adds the "XTheadVector" extension, a collection of T-Head-specific vector instructions. The 'th' prefix and the "XTheadVector" extension are documented in a PR for the RISC-V toolchain conventions ([1]). Here are some things that need to be explained: The "XTheadVector" extension is not a custom-extension, but a non-standard non-conforming extension. The encoding space of the "TheadVector" instructions overlaps with those of the 'V' extension. This encoding space conflict is not on purpose, but the result of issues in the past that have been resolved since. Therefore, the "XTheadVector" extension and the 'V' extension are in conflict.

2023-09-05RISC-V: Add stub support for the 'Svadu' extensionTsukasa OI1-0/+2
This commit implements support for 'Svadu' extension. Because it does not add any instructions or CSRs (but adds bits to existing CSRs), this commit only adds extension name support and implication to the 'Zicsr' extension.

2023-09-05RISC-V: Add 'Smcntrpmf' extension and its CSRsTsukasa OI1-0/+2
This commit adds now stable and approved 'Smcntrpmf' extension defined by the RISC-V Cycle and Instret Privilege Mode Filtering specification. Note that, because mcyclecfg and minstretcfg CSRs conflict with the privileged specification version 1.9.1, CSRs for this extension are only enabled on the privileged specification version 1.10 or later. By checking the base privileged specification, we no longer need to change the design of base CSR handling. This is based on the specification version v1.0_rc1 (Frozen): <https://github.com/riscv/riscv-smcntrpmf/commit/32b752c40d59c1b5e95de83399c1f54be6669163> bfd/ChangeLog: * elfxx-riscv.c (riscv_implicit_subsets): Add implication rule from the new 'Smcntrpmf' extension.

2023-09-05RISC-V: Prohibit combination of 'E' and 'H'Tsukasa OI1-0/+7
According to the ratified privileged specification (version 20211203), it says: > The hypervisor extension depends on an "I" base integer ISA with 32 x > registers (RV32I or RV64I), not RV32E, which has only 16 x registers.

This fact was not reflected in Binutils ('Zvfh' implies 'Zfhmin', not full 'Zfh' extension and "fli.h" required 'Zfh' and 'Zfa' extensions).

This commit adds support for recently ratified vector FP16 extensions: 'Zvfh' and 'Zvfhmin'.

Note that however, in this commit, following dependencies are implemented. 1. 'Zvfhmin' -> 'Zve32f' 2. 'Zvfh' -> 'Zvfhmin' (not 'Zvfh' -> 'Zve32f' as in the documentation) 3. 'Zvfh' -> 'Zfhmin' This is because the instructions and configurations supported by the 'Zvfh' extension is a strict superset of the 'Zvfhmin' extension and 'Zvfh' -> 'Zve32f' dependency is indirectly derived from that fact. bfd/ChangeLog: * elfxx-riscv.c (riscv_implicit_subsets): Add implications related to 'Zvfh' and 'Zvfhmin' extensions.
