target/riscv: add 'parent' in profile description Certain S-mode profiles, like RVA22S64 and RVA23S64, mandate all the mandatory extensions of their respective U-mode profiles. RVA22S64 includes all mandatory extensions of RVA22U64, and the same happens with RVA23 profiles. Add a 'parent' field to allow profiles to enable other profiles. This will allow us to describe S-mode profiles by specifying their parent U-mode profile, then adding just the S-mode specific extensions. We're naming the field 'parent' to consider the possibility of other uses (e.g. a s-mode profile including a previous s-mode profile) in the future.

meson: Introduce target-specific Kconfig Add a target-specific Kconfig. We need the definitions in Kconfig so the minikconf tool can verify they exits. However CONFIG_FOO is only enabled for target foo via the meson.build rules. Two architecture have a particularity, ARM and MIPS. As their translators have been split you can potentially build a plain 32 bit build along with a 64-bit version including the 32-bit subset.

target/riscv: Add M-mode virtual interrupt and IRQ filtering support. This change adds support for inserting virtual interrupts from M-mode into S-mode using mvien and mvip csrs. IRQ filtering is a use case of this change, i-e M-mode can stop delegating an interrupt to S-mode and instead enable it in MIE and receive those interrupts in M-mode and then selectively inject the interrupt using mvien and mvip. Also, the spec doesn't mandate the interrupt to be actually supported in hardware. Which allows M-mode to assert virtual interrupts to S-mode that have no connection to any real interrupt events. This is defined as part of the AIA specification [0], "5.3 Interrupt filtering and virtual interrupts for supervisor level".

target/riscv: implement svade 'svade' is a RVA22S64 profile requirement, a profile we're going to add shortly. It is a named feature (i.e. not a formal extension, not defined in riscv,isa DT at this moment) defined in [1] as: "Page-fault exceptions are raised when a page is accessed when A bit is clear, or written when D bit is clear.". As far as the spec goes, 'svade' is one of the two distinct modes of handling PTE_A and PTE_D. The other way, i.e. update PTE_A/PTE_D when they're cleared, is defined by the 'svadu' extension. Checking cpu_helper.c, get_physical_address(), we can verify that QEMU is compliant with that: we will update PTE_A/PTE_D if 'svadu' is enabled, or throw a page-fault exception if 'svadu' isn't enabled. So, as far as we're concerned, 'svade' translates to 'svadu must be disabled'. We'll implement it like 'zic64b': an internal flag that profiles can enable. The flag will not be exposed to users.

riscv: Add support for the Zfa extension This patch introduces the RISC-V Zfa extension, which introduces additional floating-point instructions: * fli (load-immediate) with pre-defined immediates * fminm/fmaxm (like fmin/fmax but with different NaN behaviour) * fround/froundmx (round to integer) * fcvtmod.w.d (Modular Convert-to-Integer) * fmv* to access high bits of float register bigger than XLEN * Quiet comparison instructions (fleq/fltq) Zfa defines its instructions in combination with the following extensions: * single-precision floating-point (F) * double-precision floating-point (D) * quad-precision floating-point (Q) * half-precision floating-point (Zfh) Since QEMU does not support the RISC-V quad-precision floating-point ISA extension (Q), this patch does not include the instructions that depend on this extension. All other instructions are included in this patch. The Zfa specification can be found here: https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex The Zfa specifciation is frozen and is in public review since May 3, 2023: https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg The patch also includes a TCG test for the fcvtmod.w.d instruction. The test cases test for correct results and flag behaviour. Note, that the Zfa specification requires fcvtmod's flag behaviour to be identical to a fcvt with the same operands (which is also tested).

target/riscv: Add "pmu-mask" property to replace "pmu-num" Using a mask instead of the number of PMU devices supports the accurate emulation of platforms that have a discontinuous set of PMU counters. The "pmu-num" property now generates a warning when used by the user on the command line. Rather than storing the value for "pmu-num" convert it directly to the mask if it is specified (overwriting the default "pmu-mask" value) likewise the value is calculated from the mask if the property value is obtained. In the unusual situation that both "pmu-mask" and "pmu-num" are provided then then the order on the command line determines which takes precedence (later overwriting earlier.)

riscv-qmp-cmds.c: add profile flags in cpu-model-expansion Expose all profile flags for all CPUs when executing query-cpu-model-expansion. This will allow callers to quickly determine if a certain profile is implemented by a given CPU. This includes vendor CPUs - the fact that they don't have profile user flags doesn't mean that they don't implement the profile. After this change it's possible to quickly determine if our stock CPUs implement the existing rva22u64 profile. Here's a few examples: $ ./build/qemu-system-riscv64 -S -M virt -display none -qmp tcp:localhost:1234,server,wait=off $ ./scripts/qmp/qmp-shell localhost:1234 Welcome to the QMP low-level shell! Connected to QEMU 8.1.50 - As expected, the 'max' CPU implements the rva22u64 profile. (QEMU) query-cpu-model-expansion type=full model={"name":"max"} {"return": {"model": {"name": "rv64", "props": {... "rva22u64": true, ...}}}} - rv64 is missing "zba", "zbb", "zbs", "zkt" and "zfhmin": query-cpu-model-expansion type=full model={"name":"rv64"} {"return": {"model": {"name": "rv64", "props": {... "rva22u64": false, ...}}}} query-cpu-model-expansion type=full model={"name":"rv64", "props":{"zba":true,"zbb":true,"zbs":true,"zkt":true,"zfhmin":true}} {"return": {"model": {"name": "rv64", "props": {... "rva22u64": true, ...}}}} We have no vendor CPUs that supports rva22u64 (veyron-v1 is the closest - it is missing just 'zkt'). In short, aside from the 'max' CPU, we have no CPUs that supports rva22u64 by default.

trace: switch position of headers to what Meson requires Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.
