target/riscv: add zicntr extension flag for TCG zicntr is the Base Counters and Timers extension described in chapter 12 of the unprivileged spec. It describes support for RDCYCLE, RDTIME and RDINSTRET. QEMU already implements it in TCG way before it was a discrete extension. zicntr is part of the RVA22 profile, so let's add it to QEMU to make the future profile implementation flag complete. Given than it represents an already existing feature, default it to 'true' for all CPUs. For TCG, we need a way to disable zicntr if the user wants to. This is done by restricting access to the CYCLE, TIME, and INSTRET counters via the 'ctr()' predicate when we're about to access them. Disabling zicntr happens via the command line or if its dependency, zicsr, happens to be disabled. We'll check for zicsr during realize() and, in case it's absent, disable zicntr. However, if the user was explicit about having zicntr support, error out instead of disabling it.

target/riscv: Add Zihintntl extension ISA string to DTS RVA23 Profiles states: The RVA23 profiles are intended to be used for 64-bit application processors that will run rich OS stacks from standard binary OS distributions and with a substantial number of third-party binary user applications that will be supported over a considerable length of time in the field. The chapter 4 of the unprivileged spec introduces the Zihintntl extension and Zihintntl is a mandatory extension presented in RVA23 Profiles, whose purpose is to enable application and operating system portability across different implementations. Thus the DTS should contain the Zihintntl ISA string in order to pass to software. The unprivileged spec states: Like any HINTs, these instructions may be freely ignored. Hence, although they are described in terms of cache-based memory hierarchies, they do not mandate the provision of caches. These instructions are encoded with non-used opcode, e.g. ADD x0, x0, x2, which QEMU already supports, and QEMU does not emulate cache. Therefore these instructions can be considered as a no-op, and we only need to add a new property for the Zihintntl extension.

target/riscv: add zihpm extension flag for TCG zihpm is the Hardware Performance Counters extension described in chapter 12 of the unprivileged spec. It describes support for 29 unprivileged performance counters, hpmcounter3-hpmcounter31. As with zicntr, QEMU already implements zihpm before it was even an extension. zihpm is also part of the RVA22 profile, so add it to QEMU to complement the future profile implementation. Default it to 'true' for all existing CPUs since it was always present in the code. As for disabling it, there is already code in place in target/riscv/csr.c in all predicates for these counters (ctr() and mctr()) that disables them if cpu->cfg.pmu_num is zero. Thus, setting cpu->cfg.pmu_num to zero if 'zihpm=false' is enough to disable the extension. Set cpu->pmu_avail_ctrs mask to zero as well since this is also checked to verify if the counters exist.

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.)

target/riscv: Factor out extension tests to cpu_cfg.h This patch moves the extension test functions that are used to gate vendor extension decoders, into cpu_cfg.h. This allows to reuse them in the disassembler. This patch does not introduce new functionality. However, the patch includes a small change: The parameter for the extension test functions has been changed from 'DisasContext*' to 'const RISCVCPUConfig*' to keep the code in cpu_cfg.h self-contained.
