Abstract: A data processing apparatus has a debug state in which processing circuitry 105 executes instructions received from the debug interface 115. Control changing circuitry 135 prohibits the execution of instructions in a predefined privilege mode when in the debug state if a control parameter has a predefined value. In response to a first exception being signalled while in the debug state, where the first exception is intended to be handled at the predefined privilege mode, and further in response to the control parameter having the predefined value, signalling circuitry 115 signals a second exception to be handled at a different privilege mode from the predefined privilege mode and sets information identifying a type of the first exception. Consequently, without having to enter the prohibited (predefined) privilege mode, the debugger 110 can be made aware of the first exception that would ordinarily be handled at the predefined, i.e. prohibited privilege mode.

Abstract: A data processing apparatus has processing circuitry which can execute instructions at one of several privilege levels. A plurality of performance monitoring circuits are included. In response to an instruction executed at a first privilege level, first configuration data can be set for controlling performance monitoring by a first subset of performance monitoring circuits. A disable control flag can be set in response to an instruction executed at a second privilege level higher than the first privilege level. If the disable control flag has a predetermined value then performance monitoring control circuitry disables performance monitoring by the first subset of performance monitoring circuits while the processing circuitry is executing instructions at the second privilege level.

Abstract: A data processing apparatus is provided which is configured to select 2M selected identifiers within a possible range of up to 2N identifiers, where M?N. The data processing apparatus comprises a selection storage unit configured to store at least N+1 identifier selection bits, wherein a position of a first marker bit in the at least N+1 identifier selection bits determines M, and an identifier selection unit configured to determine the 2M selected identifiers. The 2M selected identifiers fall within a range defined by a base identifier and a ceiling identifier. N-M bits of the N+1 identifier selection bits form N-M bits of the base identifier, and M zeroes form a further M bits of the base identifier. The ceiling identifier corresponds to the base identifier, except that the M zeroes of the base identifier are replaced by M ones.
