See gdbstub.txt for more information. + + +========================== +VIRTUAL INTERRUPT HANDLING +========================== + +Because accesses to the PSR is so slow, and to disable interrupts we have to access it twice (once +to read and once to write), we don't actually disable interrupts at all if we don't have to. What +we do instead is use the ICC2 condition code flags to note virtual disablement, such that if we +then do take an interrupt, we note the flag, really disable interrupts, set another flag and resume +execution at the point the interrupt happened. Setting condition flags as a side effect of an +arithmetic or logical instruction is really fast. This use of the ICC2 only occurs within the +kernel - it does not affect userspace. + +The flags we use are: + + (*) CCR.ICC2.Z [Zero flag] + + Set to virtually disable interrupts, clear when interrupts are virtually enabled. Can be + modified by logical instructions without affecting the Carry flag. + + (*) CCR.ICC2.C [Carry flag] + + Clear to indicate hardware interrupts are really disabled, set otherwise. + + +What happens is this: + + (1) Normal kernel-mode operation. + + ICC2.Z is 0, ICC2.C is 1. + + (2) An interrupt occurs. The exception prologue examines ICC2.Z and determines that nothing needs + doing. This is done simply with an unlikely BEQ instruction. + + (3) The interrupts are disabled (local_irq_disable) + + ICC2.Z is set to 1. + + (4) If interrupts were then re-enabled (local_irq_enable): + + ICC2.Z would be set to 0. + + A TIHI #2 instruction (trap #2 if condition HI - Z==0 && C==0) would be used to trap if + interrupts were now virtually enabled, but physically disabled - which they're not, so the + trap isn't taken. The kernel would then be back to state (1). + + (5) An interrupt occurs. The exception prologue examines ICC2.Z and determines that the interrupt + shouldn't actually have happened. It jumps aside, and there disabled interrupts by setting + PSR.PIL to 14 and then it clears ICC2.C. + + (6) If interrupts were then saved and disabled again (local_irq_save): + + ICC2.Z would be shifted into the save variable and masked off (giving a 1). + + ICC2.Z would then be set to 1 (thus unchanged), and ICC2.C would be unaffected (ie: 0). + + (7) If interrupts were then restored from state (6) (local_irq_restore): + + ICC2.Z would be set to indicate the result of XOR'ing the saved value (ie: 1) with 1, which + gives a result of 0 - thus leaving ICC2.Z set. + + ICC2.C would remain unaffected (ie: 0). + + A TIHI #2 instruction would be used to again assay the current state, but this would do + nothing as Z==1. + + (8) If interrupts were then enabled (local_irq_enable): + + ICC2.Z would be cleared.
