charset="utf-8" This commits groups together all CPUArchState fields whose behaviour can be retained by simply changing the size of the field. Note, senvcfg is defined to be SXLEN bits wide, but is widened to 64 bits to match henvcfg and menvcfg. Next, [m|h]edeleg are changed to 64 bits as defined privileged specification, and hvictl is fixed to 32 bits which holds all relevant values, see HVICTL_VALID_MASK. The remaining fields touched in the commit are widened from [H|S|M]XLEN to 64-bit. Note, the cpu/hyper, cpu/envcfg, cpu/jvt, and cpu VMSTATE versions are bumped, breaking migration from older versions. References to the privileged/unprivileged RISCV specification refer to version 20250508.

charset="utf-8" From my understanding the upper_half argument only indicates whether the upper or lower 32 bits should be returned, and upper_half will only ever be set when MXLEN =3D=3D 32. However, the function also uses upper_half to determine whether the inhibit flags are located in mcyclecfgh or mcyclecfg, but this misses the case where MXLEN =3D=3D 32, upper_half =3D= =3D false for TARGET_RISCV32 where we would also need to read the upper half field. Minor simplifications are also made along with some formatting fixes. Signed-off-by: Anton Johansson --- NOTE: I've not included any reviewed-bys or modified this patch as it's still unclear to me whether this change is correct or not. Alistair mentioned that this can get called for MXLEN =3D=3D 32 and upper_half =3D= =3D false, meaning the lower field would be accessed. I'm sure I'm missing something but this is still not clear to me, it seems to me like we always want to access the upper half for MXLEN =3D=3D 32 since that's were the inhibit flags are stored. --- target/riscv/csr.c | 22 ++++++++++------------ 1 file changed, 10 insertions(+), 12 deletions(-) diff --git a/target/riscv/csr.c b/target/riscv/csr.c index 5c91658c3d..657179a983 100644 --- a/target/riscv/csr.c +++ b/target/riscv/csr.c @@ -17,6 +17,7 @@ * this program.

Combine the two arrays of target_ulong mhpmeventh[] and mhpmevent[] to a single array of uint64_t. This also allows for some minor code simplification where branches handling either mhpmeventh[] or mhpmevent[] could be combined.

No real advantage is gained by keeping them separate, and combining them allows for slight simplification.

charset="utf-8" gprh is only needed for TARGET_RISCV64 when modeling 128-bit registers, fixing their size to 64 bits makes sense. gpr is also fixed to 64 bits since all direct uses of env->gpr correctly zero extend/truncate to/from target_ulong, meaning !TARGET_RISCV64 will behave as expected. We do however need to be a bit careful when mapping 64-bit fields to 32-bit TCGv globals on big endian hosts. Note, the cpu/rv128 VMSTATE version is bumped, breaking migration from older versions.
