As Richard suggested, place ALLINT bit in PSTATE in env->pstate. With the change to pstate_read/write, exception entry and return are automatically handled. Signed-off-by: Jinjie Ruan Reviewed-by: Richard Henderson --- v5: - Remove the ALLINT comment, as it is covered by "all other bits". - Add Reviewed-by. v4: - Keep PSTATE.ALLINT in env->pstate but not env->allint. - Update the commit message. v3: - Remove ALLINT dump in aarch64_cpu_dump_state(). - Update the commit message. --- target/arm/cpu.h | 1 + 1 file changed, 1 insertion(+) diff --git a/target/arm/cpu.h b/target/arm/cpu.h index bc0c84873f..de740d223f 100644 --- a/target/arm/cpu.h +++ b/target/arm/cpu.h @@ -1430,6 +1430,7 @@ void pmu_init(ARMCPU *cpu); #define PSTATE_D (1U << 9) #define PSTATE_BTYPE (3U << 10) #define PSTATE_SSBS (1U << 12) +#define PSTATE_ALLINT (1U << 13) #define PSTATE_IL (1U << 20) #define PSTATE_SS (1U << 21) #define PSTATE_PAN (1U << 22) --=20 2.34.1
