The max valid number of riscv_excp_names is 23, so the last excpetion "guest_store_page_fault" can not be printed. In addition, the current check of cause is invalid for riscv_intr_names. So introduce riscv_cpu_get_trap_name to get the trap cause name.

In a real world we can have 2 exact same CPUs except for the reset vector address, which is pretty common in the RISC-V core IP licensing business. Normally reset vector address is a configurable parameter. Let's create a 64-bit property to store the reset vector address which covers both 32-bit and 64-bit CPUs.

The Icicle Kit board integrates a PolarFire SoC, with one SiFive's E51 plus four U54 cores and many on-chip peripherals and an FPGA. For more details about Microchip PolarFire Soc, please see: https://www.microsemi.com/product-directory/soc-fpgas/5498-polarfire-soc-fpga Unlike SiFive FU540, the RISC-V core resect vector is at 0x20220000. The following perepherals are created as an unimplemented device: - Bus Error Uint 0/1/2/3/4 - L2 cache controller - SYSREG - MPUCFG - IOSCBCFG More devices will be added later. The BIOS image used by this machine is hss.bin, aka Hart Software Services, which can be built from: https://github.com/polarfire-soc/hart-software-services To launch this machine: $ qemu-system-riscv64 -nographic -M microchip-icicle-kit The memory is set to 1 GiB by default to match the hardware. A sanity check on ram size is performed in the machine init routine to prompt user to increase the RAM size to > 1 GiB when less than 1 GiB ram is detected.

In this case,the amount of extensions on top of the rv64 CPU made it compliant with the RVA22S64 profile during the validation of CPU 0. When the subsequent CPUs were initialized the static profile object has the 'enable' flag set, enabling the profile code path for those CPUs. This happens because we are initializing and realizing each CPU before going to the next, i.e. init and realize CPU0, then init and realize CPU1 and so on. If we change any persistent state during the validation of CPU N it will interfere with the init/realization of CPU N+1. We're using the 'enabled' profile flag to do two distinct things: inform cpu_init() that we want profile extensions to be enabled, and telling QMP that a profile is currently enabled in the CPU. We want to be flexible enough to recognize profile support for all CPUs that has the extension prerequisites, but we do not want to force the profile code path if a profile wasn't set too. Add a new 'present' flag for profiles that will coexist with the 'enabled' flag. Enabling a profile means "we want to switch on all its mandatory extensions". A profile is 'present' if we asserted during validation that the CPU has the needed prerequisites. This means that the case reported by Björn now results in RVA22S64.enabled=false and RVA22S64.present=true. QMP will recognize it as a RVA22 compliant CPU and we won't force the CPU into the profile path.

Current implementation is not atomic because it loads instruction twice for first and last 2 bytes. We load 4 bytes at once to keep the atomicity. This instruction preload method only applys when instruction is 4-byte aligned. If instruction is unaligned, it could be across pages so that preload will trigger additional page fault. We encounter this issue when doing pressure test of enabling & disabling Linux kernel ftrace. Ftrace with kernel preemption requires concurrent modification and execution of instruction, so non-atomic instruction fetch will cause the race condition. We may fetch the wrong instruction which is the mixing of 2 instructions. Also, RISC-V Profile wants to provide this feature by HW. RVA20U64 Ziccif protects the atomicity of instruction fetch when it is natural aligned. This commit depends on the atomic read support of translator_ld in the commit 6a9dfe1984b0c593fb0ddb52d4e70832e6201dd6.

When software writes to TXFIFO faster than the async callback delay (100ns), the timer may be pushed back while the previous character has not be dequeued yet. This happens in particular when using -icount with small shift values. This is especially worrysome when software repetitively issues amoor.w instructions (as suggested by SiFive specification) and the FIFO is full, leading to the callback being infinitly pushed back. This commit fixes the issue by never pushing back the timer, only updating it if it is not already active.

When IALIGN=32, the two low bits must be zero. This commit fixes the behavior of MEPC/SEPC CSR reads and writes, and the implicit reads by MRET/SRET instructions to properly mask the lowest bit(s) based on whether the C extension is enabled: - When C extension is enabled (IALIGN=16): mask bit 0 - When C extension is disabled (IALIGN=32): mask bits [1:0] Previously, when vectored mode bits from STVEC (which sets bit 0 for vectored mode) were written to MEPC, the bits would not be cleared correctly, causing incorrect behavior on MRET.
