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.

When shifting these addresses left (e.g., `this_addr << 2`), an integer overflow occurs, truncating the high bits of the 34-bit physical address.

This means currently we incorrectly treat the LCOFIP bit as delegable, even if AIA is disabled, which is incorrect (see the issues mentioned below). The AIA spec indicates that implementations can determine which bits of 13-63 in mvien are writable, so let's just make it bits 15-63 to match the main spec.

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.

The PHY on each may be connected to separate MDIO busses, or both may be connected on the same MDIO bus using different PHY addresses. To be able to support two PHY instances on a single MDIO bus, two properties are needed: First, there needs to be a flag indicating if the MDIO bus on a given Ethernet interface is connected. If not, attempts to read from this bus must always return 0xffff. Implement this property as phy-connected. Second, if the MDIO bus on an interface is active, it needs a link to the consumer interface to be able to provide PHY access for it. Implement this property as phy-consumer.

I'll also just post verbatim Bo Gan comment in the commit msg: "In RISCV Linux with KVM enabled, gdbstub is broken. The get_physical_address isn't able to page-walk correctly and resolve the physical page. This is due to that the vcpu is being treated as starting in M mode even if KVM enabled. However, with KVM, the vcpu is actually started in S mode. The mmu_idx will give 3 (M), instead of 1 (S), resulting in Guest PA == VA (wrong)!"

In theory that will never happen - it's guaranteed that both "reg1" and "reg2" is non-NULL because we're retrieving them in compile-time from static arrays. Coverity doesn't know that though. To make Coverity happier and add a bit more clarity in the code, g_assert() each token to make it clear that those 2 values aren't supposed to be NULL ever.
