2025-07-21target/arm: Add BFMUL (indexed)Peter Maydell4-1/+5
FEAT_SVE_B16B16 adds a bfloat16 version of the FMUL insn in the floating-point multiply (indexed) instruction group. The encoding is slightly bespoke; in our implementation we use MO_8 to indicate bfloat16, as with the other B16B16 insns.

FEAT_SVE_B16B16 adds bfloat16 versions of the SVE floating point (predicated) instructions, which are encoded via sz=0b00. Add the BFMAX and BFMIN insns. These have separate behaviour for AH=1 and AH=0; we have already implemented the AH=1 helper for the SME2 versions of these insns.

FEAT_SVE_B16B16 adds bfloat16 versions of the SVE floating point (predicated) instructions, which are encoded via sz=0b00. Add BFADD, BFSUB, BFMUL, BFMAXNM, BFMINNM; these are all the insns in this group which do not change behaviour for AH=1.

2025-07-21target/arm: Provide always-false kvm_arm_*_supported() stubs for usermodePeter Maydell1-0/+35
If you try to build aarch64-linux-user with clang and --enable-debug then it fails to compile: ld: libqemu-aarch64-linux-user.a.p/target_arm_cpu64.c.o: in function `cpu_arm_set_sve': ../../target/arm/cpu64.c:321:(.text+0x1254): undefined reference to `kvm_arm_sve_supported' This is a regression introduced in commit f86d4220, which switched the kvm-stub.c file away from being built for all arm targets to only being built for system emulation binaries. It doesn't affect gcc, presumably because even at -O0 gcc folds away the always-false kvm_enabled() condition but clang does not. We would prefer not to build kvm-stub.c once for usermode and once for system-emulation binaries, and we can't build it just once for both because it includes cpu.h. So instead provide always-false versions of the five functions that are valid to call without KVM support in kvm_arm.h.

2025-07-21target/arm: Correct encoding of Debug Communications Channel registersPeter Maydell1-2/+11
We don't implement the Debug Communications Channel (DCC), but we do attempt to provide dummy versions of its system registers so that software that tries to access them doesn't fall over. However, we got the tx/rx register definitions wrong. These should be: AArch32: DBGDTRTX p14 0 c0 c5 0 (on writes) DBGDTRRX p14 0 c0 c5 0 (on reads) AArch64: DBGDTRTX_EL0 2 3 0 5 0 (on writes) DBGDTRRX_EL0 2 3 0 5 0 (on reads) DBGDTR_EL0 2 3 0 4 0 (reads and writes) where DBGDTRTX and DBGDTRRX are effectively different names for the same 32-bit register, which has tx behaviour on writes and rx behaviour on reads. The AArch64-only DBGDTR_EL0 is a 64-bit wide register whose top and bottom halves map to the DBGDTRRX and DBGDTRTX registers. Currently we have just one cpreg struct, which: * calls itself DBGDTR_EL0 * uses the DBGDTRTX_EL0/DBGDTRRX_EL0 encoding * is marked as ARM_CP_STATE_BOTH but has the wrong opc1 value for AArch32 * is implemented as RAZ/WI Correct the encoding so: * we name the DBGDTRTX/DBGDTRRX register correctly * we split it into AA64 and AA32 versions so we can get the AA32 encoding right * we implement DBGDTR_EL0 at its correct encoding Cc: qemu-stable@nongnu.org Resolves: https://gitlab.com/qemu-project/qemu/-/issues/2986 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20250708141049.778361-1-peter.maydell@linaro.org

We don't synchronize vcpu registers from the hardware accelerator (e.g., by cpu_synchronize_state()) in the Dabort handler, so env->pc points to the instruction which has nothing to do with the Dabort at all. And it doesn't seem to make much sense to log PC in every Dabort handler, let's just remove it from this trace event.

In the Arm ARM, rule R_TYTWB that defines illegal exception return cases includes the case: If FEAT_RME is implemented, then if SCR_EL3.{NSE, NS} is {1, 0}, an exception return from EL3 to a lower Exception level Our implementation of this check fails to check that the return is to a lower exception level, so it will incorrectly fire on EL3->EL3 exception returns. Fix the check condition. This requires us to move it further down in the function to a point where we know the new_el value.
