Skip it altogether in this case. Aside from the code simplification there's a noticeable emulation performance gain by doing it. For a regular C binary that does a vectors operation like this: ======= #define SZ 10000000 int main () { int *a = malloc (SZ * sizeof (int)); int *b = malloc (SZ * sizeof (int)); int *c = malloc (SZ * sizeof (int)); for (int i = 0; i < SZ; i++) c[i] = a[i] + b[i]; return c[SZ - 1]; } ======= Emulating it with qemu-riscv64 and RVV takes ~0.3 sec: $ time ~/work/qemu/build/qemu-riscv64 \ -cpu rv64,debug=false,vext_spec=v1.0,v=true,vlen=128 ./foo.out real 0m0.303s user 0m0.281s sys 0m0.023s With this skip we take ~0.275 sec: $ time ~/work/qemu/build/qemu-riscv64 \ -cpu rv64,debug=false,vext_spec=v1.0,v=true,vlen=128 ./foo.out real 0m0.274s user 0m0.252s sys 0m0.019s This performance gain adds up fast when executing heavy benchmarks like SPEC.

CPUs such as sifive_e need to disable settings that aren't enabled simply because the parent class happens to be enabling it.

We want to open code just the bits that are exclusive to the CSR write operation and TCG internals. Our validation is done with riscv_cpu_validate_set_extensions(), but we need a small tweak first. When enabling RVG we're doing: env->misa_ext |= RVI | RVM | RVA | RVF | RVD; env->misa_ext_mask = env->misa_ext; This works fine for realize() time but this can potentially overwrite env->misa_ext_mask if we reutilize the function for write_misa(). Instead of doing misa_ext_mask = misa_ext, sum up the RVG extensions in misa_ext_mask as well. This won't change realize() time behavior (misa_ext_mask will be == misa_ext) and will ensure that write_misa() won't change misa_ext_mask by accident. After that, rewrite write_misa() to work as follows: - mask the write using misa_ext_mask to avoid enabling unsupported extensions; - suppress RVC if the next insn isn't aligned; - disable RVG if any of RVG dependencies are being disabled by the user; - assign env->misa_ext and run riscv_cpu_validate_set_extensions(). On error, rollback env->misa_ext to its original value, logging a GUEST_ERROR to inform the user about the failed write; - handle RVF and MSTATUS_FS and continue as usual. Let's keep write_misa() as experimental for now until this logic gains enough mileage.

However, the first pflash is always assumed to contain M-mode firmware and reset vector is set to this if enabled. Hence, for S-mode payloads like EDK2, only one pflash instance is available for use. This means both code and NV variables of EDK2 will need to use the same pflash. The OS distros keep the EDK2 FW code as readonly. When non-volatile variables also need to share the same pflash, it is not possible to keep it as readonly since variables need write access. To resolve this issue, the code and NV variables need to be separated. But in that case we need an extra flash. Hence, modify the convention for non-KVM guests such that, pflash0 will contain the M-mode FW only when "-bios none" option is used. Otherwise, pflash0 will contain the S-mode payload FW. This enables both pflash instances available for EDK2 use. When KVM is enabled, pflash0 is always assumed to contain the S-mode payload firmware only.

Actually, the max_elements derived in vext_ld*() won't be a fraction of vector register size, since the lmul encoded in desc is emul, which has already been adjusted to 1 for LMUL fragmentation case by vext_get_emul() in trans_rvv.c.inc, for ld_stride(), ld_us(), ld_index() and ldff(). Besides, vext_get_emul() has also taken EEW/SEW into consideration, so no need to call vext_get_total_elems() which would base on the emul to derive another emul, the second emul would be incorrect when esz differs from sew. Thus this patch removes the check for extra tail elements.

According to the RISC-V Privileged Specification, mseccfg exists if any extension that adds a field to it is implemented. Currently, the `have_mseccfg()` predicate function checks for Smepmp, Zkr, and Smmpm, but misses Zicfilp. As a result, if a CPU is configured with `zicfilp=true` but without the other extensions, accessing the mseccfg CSR will incorrectly raise an illegal instruction exception. This patch adds the missing check for `ext_zicfilp` to ensure the CSR is properly accessible when the Zicfilp extension is enabled. This issue was discovered and reported by SpecHunter, an AI-driven architecture specification analysis tool.

The IOMMU model wasn't checking PTE_N and therefore was using the raw (NAPOT- encoded) PPN directly in the physical address, yielding an address 32 KB above the correct base. Fix both riscv_iommu_spa_fetch() and pdt_memory_read() by mirroring the Svnapot handling already present in target/riscv/cpu_helper.c: napot_bits = ctz64(ppn) + 1 /* 4 for 64KB */ napot_mask = (1 << napot_bits) - 1 /* 0xF */ phys_base = PPN_PHYS(ppn & ~napot_mask) page_offset = addr & (PPN_PHYS(napot_mask) | (TARGET_PAGE_SIZE - 1)) The spec only defines napot_bits == 4 (64KB); any other value is treated as a reserved encoding. This is a fix, rather than new feature support, because the spec says "IOMMU implementations must support the Svnapot standard extension for NAPOT Translation Contiguity."

When QEMU runs with rvv_ta_all_1s enabled, those elements must therefore become all 1s. QEMU handled both instructions as translation-time special cases that directly wrote vd[0] and skipped the usual tail processing. As a result, vmv.s.x and vfmv.s.f left the remaining destination elements unchanged instead of applying the configured tail policy. Fix this by routing both instructions through a helper that writes vd[0] and then treats the rest of the destination register as tail, reusing the existing agnostic-element fill logic.

However, the current QEMU implementation uses `target_ulong` (which resolves to `uint32_t` on RV32) for PMP address variables. When shifting these addresses left (e.g., `this_addr << 2`), an integer overflow occurs, truncating the high bits of the 34-bit physical address. Fix this issue by changing the types of PMP address variables (`this_addr` and `prev_addr`) to `hwaddr`.

For devices behind bridges, pci_bus_num() can return 0 at that point because the guest has not yet programmed the bridge Secondary Bus Number register. The RISC-V IOMMU currently stores a fixed device_id in RISCVIOMMUSpace when the address space is created. If the guest later enumerates the device on a non-zero bus, DMA translation still uses the stale device_id and may look up the wrong device context in the DDT. Store the stable PCIBus pointer and devfn in RISCVIOMMUSpace instead, and compute the device_id from the current bus number when it is needed. This keeps DMA translation and ATS invalidation in sync with guest PCI bus enumeration.

To do that we'll have to make isa_edata_arr[] do what the other arrays are currently doing, not breaking existing semantics in the process. The riscv_cpu_* arrays have a few exclusive uses: - set default extensions for rv32 and rv64; - create user CPU properties; - misc uses around tcg-cpu.c and kvm-cpu.c. We'll slowly make isa_edata_arr[] supersede these arrays. Start by adding a new 'prop_name' field in RISCVIsaExtData. This field is needed because not all extensions have properties and not all properties match the riscv,isa string name. Create two additional macros and reclassify existing isa_edata_arr[] entries as follows: - ISA_EXT_DATA_ENTRY creates an entry where prop_name == riscv,isa. Most of our regular extensions fall into this category; - ISA_EXPERIMENTAL_EXT_DATA_ENTRY: same as above but add a "x-" to the prop name, i.e. prop_name == "x-" + riscv,isa; - ISA_INTERNAL_EXT_DATA_ENTRY: used to declared internal extensions. By 'internal' we mean users/management can't set them on or off. With these new macros we can start our simplification by changing riscv-qmp-cmds to use isa_edata_arr[]. We'll just scroll through it once and gather what we need.

Back in that time we were adding RVA22 profile support and we were dealing with a RVI innovation: named features. These can be define as cute names for pre-existing behavior/parameters, e.g. 'zic64b' means all cache blocks must have 64 bytes. They do get inserted in the riscv,isa but they are not "real" extensions because users shouldn't be setting them in the command line, or so we thought back then, and we attempted to model that by calling it "named features". This didn't age that well: ziccrse is a so called named feature as far as TCG goes, but then KVM had to treat it as a regular extension that can be user set and we made an exception: ziccrse is a named feature that is user set by KVM. "Named features" are regular extensions that might or might not be user set, and might or might not warrant special handling during realize() by setting other parameters. And we'll being treating them as such, which will culminate in the end of riscv_cpu_named_features[] array in the end. This reverts commit 7e4f75cadf44ee67809c7ca82645a289a5268966.

For a System IOMMU, `s->pci_iommu_bdf` is 0. This results in a `num_ids` value of 0xffff. Since the source ID base starts at 0, the mapping only covers Requester IDs from 0 to 0xfffe. The final valid PCI Requester ID (0xffff) is erroneously omitted from the RIMT table. Fix this by decoupling the `num_ids` calculation. For System IOMMUs, explicitly set `num_ids` to 0x10000 to cover the entire PCI Requester ID space. This issue was discovered and reported by SpecHunter, an AI-driven architecture specification analysis tool.

Currently, QEMU APLIC only clears the pending bit when interrupt is claimed in APLIC, but not clears it when the rectified input value is low. (e.g. IRQ source signal is low in the LEVEL_HIGH/Level1 mode). The software may receive an additional IRQ if the peripheral triggers one after the software clears the APLIC IRQ but before it clears the peripheral's IRQ. Thus, we also clear the pending bit via the rectified input value in the level-trigger mode. This change doesn't affect MSI delivery mode. Calling riscv_aplic_msi_irq_update() when IRQ pending is low will do nothing.

Per RISC-V IOMMU specification : If command-queue access leads to a memory fault then the command-queue-memory-fault bit is set to 1 and the commandqueue stalls until this bit is cleared. To re-enable command processing, software should clear this bit by writing 1.
