2023-09-13target/i386: Call accel-agnostic x86_cpu_get_supported_cpuid()Philippe Mathieu-Daudé1-16/+16
x86_cpu_get_supported_cpuid() is generic and handles the different accelerators. Use it instead of kvm_arch_get_supported_cpuid(). That fixes a link failure introduced by commit 3adce820cf ("target/i386: Remove unused KVM stubs") when QEMU is configured as: $ ./configure --cc=clang \ --target-list=x86_64-linux-user,x86_64-softmmu \ --enable-debug We were getting: [71/71] Linking target qemu-x86_64 FAILED: qemu-x86_64 /usr/bin/ld: libqemu-x86_64-linux-user.fa.p/target_i386_cpu.c.o: in function `cpu_x86_cpuid': cpu.c:(.text+0x1374): undefined reference to `kvm_arch_get_supported_cpuid' /usr/bin/ld: libqemu-x86_64-linux-user.fa.p/target_i386_cpu.c.o: in function `x86_cpu_filter_features': cpu.c:(.text+0x81c2): undefined reference to `kvm_arch_get_supported_cpuid' /usr/bin/ld: cpu.c:(.text+0x81da): undefined reference to `kvm_arch_get_supported_cpuid' /usr/bin/ld: cpu.c:(.text+0x81f2): undefined reference to `kvm_arch_get_supported_cpuid' /usr/bin/ld: cpu.c:(.text+0x820a): undefined reference to `kvm_arch_get_supported_cpuid' /usr/bin/ld: libqemu-x86_64-linux-user.fa.p/target_i386_cpu.c.o:cpu.c:(.text+0x8225): more undefined references to `kvm_arch_get_supported_cpuid' follow clang: error: linker command failed with exit code 1 (use -v to see invocation) ninja: build stopped: subcommand failed. For the record, this is because '--enable-debug' disables optimizations (CFLAGS=-O0). While at this (un)optimization level GCC eliminate the following dead code (CPP output of mentioned build): static void x86_cpu_get_supported_cpuid(uint32_t func, uint32_t index, uint32_t *eax, uint32_t *ebx, uint32_t *ecx, uint32_t *edx) { if ((0)) { *eax = kvm_arch_get_supported_cpuid(kvm_state, func, index, R_EAX); *ebx = kvm_arch_get_supported_cpuid(kvm_state, func, index, R_EBX); *ecx = kvm_arch_get_supported_cpuid(kvm_state, func, index, R_ECX); *edx = kvm_arch_get_supported_cpuid(kvm_state, func, index, R_EDX); } else if (0) { *eax = 0; *ebx = 0; *ecx = 0; *edx = 0; } else { *eax = 0; *ebx = 0; *ecx = 0; *edx = 0; } Clang does not (see commit 2140cfa51d "i386: Fix build by providing stub kvm_arch_get_supported_cpuid()").

Enabling AP-passthrough(AP-pt) for PV-guest by using the new CPU features for PV-AP-pt of KVM. As usual QEMU first checks which CPU features are available and then sets them if available and selected by user. An additional check is done to verify that PV-AP can only be enabled if "regular" AP-pt is enabled as well. Note that KVM itself does not enforce this restriction.

riscv_trigger_init() had been called on reset events that can happen several times for a CPU and it allocated timers for itrigger. If old timers were present, they were simply overwritten by the new timers, resulting in a memory leak. Divide riscv_trigger_init() into two functions, namely riscv_trigger_realize() and riscv_trigger_reset() and call them in appropriate timing. The timer allocation will happen only once for a CPU in riscv_trigger_realize().

2023-09-11hw/intc/riscv_aplic.c fix non-KVM --enable-debug buildDaniel Henrique Barboza2-0/+6
Commit 6df0b37e2ab breaks a --enable-debug build in a non-KVM environment with the following error: /usr/bin/ld: libqemu-riscv64-softmmu.fa.p/hw_intc_riscv_aplic.c.o: in function `riscv_kvm_aplic_request': ./qemu/build/../hw/intc/riscv_aplic.c:486: undefined reference to `kvm_set_irq' collect2: error: ld returned 1 exit status This happens because the debug build will poke into the 'if (is_kvm_aia(aplic->msimode))' block and fail to find a reference to the KVM only function riscv_kvm_aplic_request(). There are multiple solutions to fix this. We'll go with the same solution from the previous patch, i.e. add a kvm_enabled() conditional to filter out the block. But there's a catch: riscv_kvm_aplic_request() is a local function that would end up being used if the compiler crops the block, and this won't work. Quoting Richard Henderson's explanation in [1]: "(...) the compiler won't eliminate entire unused functions with -O0" We'll solve it by moving riscv_kvm_aplic_request() to kvm.c and add its declaration in kvm_riscv.h, where all other KVM specific public functions are already declared. Other archs handles KVM specific code in this manner and we expect to do the same from now on.

2023-09-11target/riscv: fix satp_mode_finalize() when satp_mode.supported = 0Daniel Henrique Barboza1-3/+20
In the same emulated RISC-V host, the 'host' KVM CPU takes 4 times longer to boot than the 'rv64' KVM CPU. The reason is an unintended behavior of riscv_cpu_satp_mode_finalize() when satp_mode.supported = 0, i.e. when cpu_init() does not set satp_mode_max_supported(). satp_mode_max_from_map(map) does: 31 - __builtin_clz(map) This means that, if satp_mode.supported = 0, satp_mode_supported_max wil be '31 - 32'. But this is C, so satp_mode_supported_max will gladly set it to UINT_MAX (4294967295). After that, if the user didn't set a satp_mode, set_satp_mode_default_map(cpu) will make cfg.satp_mode.map = cfg.satp_mode.supported So satp_mode.map = 0. And then satp_mode_map_max will be set to satp_mode_max_from_map(cpu->cfg.satp_mode.map), i.e. also UINT_MAX. The guard "satp_mode_map_max > satp_mode_supported_max" doesn't protect us here since both are UINT_MAX. And finally we have 2 loops: for (int i = satp_mode_map_max - 1; i >= 0; --i) { Which are, in fact, 2 loops from UINT_MAX -1 to -1. This is where the extra delay when booting the 'host' CPU is coming from. Commit 43d1de32f8 already set a precedence for satp_mode.supported = 0 in a different manner. We're doing the same here. If supported == 0, interpret as 'the CPU wants the OS to handle satp mode alone' and skip satp_mode_finalize(). We'll also put a guard in satp_mode_max_from_map() to assert out if map is 0 since the function is not ready to deal with it.

2023-09-11target/riscv: Add Zihintntl extension ISA string to DTSJason Chien2-0/+3
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.

The AES MixColumns and InvMixColumns operations are relatively expensive 4x4 matrix multiplications in GF(2^8), which is why C implementations usually rely on precomputed lookup tables rather than performing the calculations on demand. Given that we already carry those tables in QEMU, we can just grab the right value in the implementation of the RISC-V AES32 instructions. Note that the tables in question are permuted according to the respective Sbox, so we can omit the Sbox lookup as well in this case.
