2023-11-03target/loongarch: Allow user enable/disable LSX/LASX featuresSong Gao
Some users may not need LSX/LASX, this patch allows the user enable/disable LSX/LASX features. e.g '-cpu max,lsx=on,lasx=on' (default); '-cpu max,lsx=on,lasx=off' (enabled LSX); '-cpu max,lsx=off,lasx=on' (enabled LASX, LSX); '-cpu max,lsx=off' (disable LSX and LASX).

2023-11-02target/arm: Correctly propagate stage 1 BTI guarded bit in a two-stage walkPeter Maydell
In a two-stage translation, the result of the BTI guarded bit should be the guarded bit from the first stage of translation, as there is no BTI guard information in stage two. Our code tried to do this, but got it wrong, because we currently have two fields where the GP bit information might live (ARMCacheAttrs::guarded and CPUTLBEntryFull::extra::arm::guarded), and we were storing the GP bit in the latter during the stage 1 walk but trying to copy the former in combine_cacheattrs(). Remove the duplicated storage, and always use the field in CPUTLBEntryFull; correctly propagate the stage 1 value to the output in get_phys_addr_twostage(). Note for stable backports: in v8.0 and earlier the field is named result->f.guarded, not result->f.extra.arm.guarded.

2023-11-02target/arm: Make FEAT_MOPS SET* insns handle Xs == XZR correctlyPeter Maydell
Most of the registers used by the FEAT_MOPS instructions cannot use 31 as a register field value; this is CONSTRAINED UNPREDICTABLE to NOP or UNDEF (we UNDEF). However, it is permitted for the "source value" register for the memset insns SET* to be 31, which (as usual for most data-processing insns) means it should be the zero register XZR. We forgot to handle this case, with the effect that trying to set memory to zero with a "SET* Xd, Xn, XZR" sets the memory to the value that happens to be in the low byte of SP. Handle XZR when getting the SET* data value from the register file.

2023-10-27target/arm: Fix syndrome for FGT traps on ERETPeter Maydell
In commit 442c9d682c94fc2 when we converted the ERET, ERETAA, ERETAB instructions to decodetree, the conversion accidentally lost the correct setting of the syndrome register when taking a trap because of the FEAT_FGT HFGITR_EL1.ERET bit. Instead of reporting a correct full syndrome value with the EC and IL bits, we only reported the low two bits of the syndrome, because the call to syn_erettrap() got dropped. Fix the syndrome values for these traps by reinstating the syn_erettrap() calls.

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>
