2023-02-07hw/riscv: split fdt address calculation from fdt loadDaniel Henrique Barboza
A common trend in other archs is to calculate the fdt address, which is usually straightforward, and then calling a function that loads the fdt/dtb by using that address. riscv_load_fdt() is doing a bit too much in comparison. It's calculating the fdt address via an elaborated heuristic to put the FDT at the bottom of DRAM, and "bottom of DRAM" will vary across boards and configurations, then it's actually loading the fdt, and finally it's returning the fdt address used to the caller. Reduce the existing complexity of riscv_load_fdt() by splitting its code into a new function, riscv_compute_fdt_addr(), that will take care of all fdt address logic. riscv_load_fdt() can then be a simple function that just loads a fdt at the given fdt address. We're also taken the opportunity to clarify the intentions and assumptions made by these functions. riscv_load_fdt() is now receiving a hwaddr as fdt_addr because there is no restriction of having to load the fdt in higher addresses that doesn't fit in an uint32_t.

2023-02-07hw/riscv/virt.c: rename MachineState 'mc' pointers to 'ms'Daniel Henrique Barboza
We have a convention in other QEMU boards/archs to name MachineState pointers as either 'machine' or 'ms'. MachineClass pointers are usually called 'mc'. The 'virt' RISC-V machine has a lot of instances where MachineState pointers are named 'mc'. There is nothing wrong with that, but we gain more compatibility with the rest of the QEMU code base, and easier reviews, if we follow QEMU conventions. Rename all 'mc' MachineState pointers to 'ms'. This is a very tedious and mechanical patch that was produced by doing the following: - find/replace all 'MachineState *mc' to 'MachineState *ms'; - find/replace all 'mc->fdt' to 'ms->fdt'; - find/replace all 'mc->smp.cpus' to 'ms->smp.cpus'; - replace any remaining occurrences of 'mc' that the compiler complained about.

2023-02-07hw/riscv/virt.c: calculate socket count once in create_fdt_imsic()Daniel Henrique Barboza
riscv_socket_count() returns either ms->numa_state->num_nodes or 1 depending on NUMA support. In any case the value can be retrieved only once and used in the rest of the function. This will also alleviate the rename we're going to do next by reducing the instances of MachineState 'mc' inside hw/riscv/virt.c.

2023-02-07target/riscv: Ensure opcode is saved for all relevant instructionsAnup Patel
We should call decode_save_opc() for all relevant instructions which can potentially generate a virtual instruction fault or a guest page fault because generating transformed instruction upon guest page fault expects opcode to be available. Without this, hypervisor will see transformed instruction as zero in htinst CSR for guest MMIO emulation which makes MMIO emulation in hypervisor slow and also breaks nested virtualization.

2023-02-07hw/riscv: boot: Don't use CSRs if they are disabledAlistair Francis
If the CSRs and CSR instructions are disabled because the Zicsr extension isn't enabled then we want to make sure we don't run any CSR instructions in the boot ROM. This patches removes the CSR instructions from the reset-vec if the extension isn't enabled. We replace the instruction with a NOP instead. Note that we don't do this for the SiFive U machine, as we are modelling the hardware in that case.
