2023-10-27target/arm: Move feature test functions to their own headerPeter Maydell
The feature test functions isar_feature_*() now take up nearly a thousand lines in target/arm/cpu.h. This header file is included by a lot of source files, most of which don't need these functions. Move the feature test functions to their own header file.

2023-10-27target/arm: Implement Neoverse N2 CPU modelPeter Maydell
Implement a model of the Neoverse N2 CPU. This is an Armv9.0-A processor very similar to the Cortex-A710. The differences are: * no FEAT_EVT * FEAT_DGH (data gathering hint) * FEAT_NV (not yet implemented in QEMU) * Statistical Profiling Extension (not implemented in QEMU) * 48 bit physical address range, not 40 * CTR_EL0.DIC = 1 (no explicit icache cleaning needed) * PMCR_EL0.N = 6 (always 6 PMU counters, not 20) Because it has 48-bit physical address support, we can use this CPU in the sbsa-ref board as well as the virt board.

This was introduced in KVM in Linux 3.5, we can require it unconditionally in kvm_irqchip_send_msi().

ARM uses it to detect the presence of the ITS emulation in the kernel, introduced in Linux 4.8. Assume that it's there and possibly fail when realizing the arm-its-kvm device.

2023-10-25target/i386: validate VEX.W for AVX instructionsPaolo Bonzini
Instructions in VEX exception class 6 generally look at the value of VEX.W. Note that the manual places some instructions incorrectly in class 4, for example VPERMQ which has no non-VEX encoding and no legacy SSE analogue. AMD does a mess of its own, as documented in the comment that this patch adds. Most of them are checked for VEX.W=0, and are listed in the manual (though with an omission) in table 2-16; VPERMQ and VPERMPD check for VEX.W=1, which is only listed in the instruction description. Others, such as VPSRLV, VPSLLV and the FMA3 instructions, use VEX.W to switch between a 32-bit and 64-bit operation. Fix more of the class 4/class 6 mismatches, and implement the check for VEX.W in TCG. Acked-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-10-25target/i386: group common checks in the decoding phasePaolo Bonzini
In preparation for adding more similar checks, move the VEX.L=0 check and several X86_SPECIAL_* checks to a new field, where each bit represent a common check on unused bits, or a restriction on the processor mode. Likewise, many SVM intercepts can be checked during the decoding phase, the main exception being the selective CR0 write, MSR and IOIO intercepts.

2023-10-25target/i386: implement SHA instructionsPaolo Bonzini
The implementation was validated with OpenSSL and with the test vectors in https://github.com/rust-lang/stdarch/blob/master/crates/core_arch/src/x86/sha.rs. The instructions provide a ~25% improvement on hashing a 64 MiB file: runtime goes down from 1.8 seconds to 1.4 seconds; instruction count on the host goes down from 5.8 billion to 4.8 billion with slightly better IPC too. Good job Intel. ;) Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
