2019-01-21target/arm: Add array for supported PMU events, generate PMCEID[01]_EL0Aaron Lindsay
This commit doesn't add any supported events, but provides the framework for adding them. We store the pm_event structs in a simple array, and provide the mapping from the event numbers to array indexes in the supported_event_map array. Because the value of PMCEID[01] depends upon which events are supported at runtime, generate it dynamically.

2019-01-21target/arm: Swap PMU values before/after migrationsAaron Lindsay
Because of the PMU's design, many register accesses have side effects which are inter-related, meaning that the normal method of saving CP registers can result in inconsistent state. These side-effects are largely handled in pmu_op_start/finish functions which can be called before and after the state is saved/restored. By doing this and adding raw read/write functions for the affected registers, we avoid migration-related inconsistencies.

2019-01-21target/arm: Reorganize PMCCNTR accessesAaron Lindsay
pmccntr_read and pmccntr_write contained duplicate code that was already being handled by pmccntr_sync. Consolidate the duplicated code into two functions: pmccntr_op_start and pmccntr_op_finish. Add a companion to c15_ccnt in CPUARMState so that we can simultaneously save both the architectural register value and the last underlying cycle count - this ensures time isn't lost and will also allow us to access the 'old' architectural register value in order to detect overflows in later patches.

2019-01-21target/arm: Allow Aarch32 exception return to switch from Mon->HypAlexander Graf
In U-boot, we switch from S-SVC -> Mon -> Hyp mode when we want to enter Hyp mode. The change into Hyp mode is done by doing an exception return from Mon. This doesn't work with current QEMU. The problem is that in bad_mode_switch() we refuse to allow the change of mode. Note that bad_mode_switch() is used to do validation for two situations: (1) changes to mode by instructions writing to CPSR.M (ie not exception take/return) -- this corresponds to the Armv8 Arm ARM pseudocode Arch32.WriteModeByInstr (2) changes to mode by exception return Attempting to enter or leave Hyp mode via case (1) is forbidden in v8 and UNPREDICTABLE in v7, and QEMU is correct to disallow it there. However, we're already doing that check at the top of the bad_mode_switch() function, so if that passes then we should allow the case (2) exception return mode changes to switch into Hyp mode. We want to test whether we're trying to return to the nonexistent "secure Hyp" mode, so we need to look at arm_is_secure_below_el3() rather than arm_is_secure(), since the latter is always true if we're in Mon (EL3).
