procedure ARMv8ContextSwitch(OldStack,NewStack:Pointer; NewThread:TThreadHandle); assembler; nostackframe;

Description: Perform a context switch from one thread to another as a result of a thread yielding, sleeping or waiting

OldStack	The address to save the stack pointer to for the current thread (Passed in r0)
NewStack	The address to restore the stack pointer from for the new thread (Passed in r1)
NewThread	The handle of the new thread to switch to (Passed in r2)
Note	At the point of the actual context switch (str sp/ldr sp) the thread stacks will look like this: (See: ARMv8ThreadSetupStack for additional information) (Base "Highest Address" of Stack) . . . . cpsr <- The current program status register value to load on return from the context switch lr/pc <- The address to return to from the context switch lr <- The lr value prior to the context switch r12 <- r11 <- r10 <- r9 <- r8 <- r7 <- r6 <- The value of these registers prior to the context switch r5 <- r4 <- r3 <- r2 <- r1 <- r0 <- d15 <- d14 <- d13 <- d12 <- d11 <- d10 <- d9 <- d8 <- The value of these floating point registers prior to the context switch d7 <- d6 <- d5 <- d4 <- d3 <- d2 <- d1 <- d0 <- fpscr <- The floating point FPSCR register fpexc <- The floating point FPEXC register (Current StackPointer points to here) . . . . (Top "Lowest Address" of Stack) This form of context switch uses r12 to save the cpsr value (and RFE to restore it). Because this context switch is called from a routine which will have saved the value of r12 (which is caller save in the ARM ABI) then we do not need to save the original value of r12. The context switch will be performed from SYS mode to SYS mode, the cpsr value will include the control bits (Mode and IRQ/FIQ state) but not the flags values. Again the ARM ABI does not require that the flags be saved by the callee and so the caller would have accounted for any needed flags before calling. If the thread to be resumed was interrupted by an IRQ or FIQ then the cpsr will also contain the flags etc as they were at the point of interrupt. We do not need to account for the state bits in the cpsr since all operations are performed in ARM mode at present. The main requirement of this routine is to ensure that the context record on the stack matches exactly that which is created on an interrupt and also that created by ThreadSetupStack for a new thread. If this is correct then the next context switch for any given thread can be either by a call to reschedule or by an interrupt. Equally a new thread can be first run from a context switch that resulted from either a call to reschedule or an interrupt. Note that this routine could use: pop (lr) pop (r12) msr cpsr_c, r12 mov pc, lr To return but that would mess up the value of r12, lr and the cpsr flags etc if the thread being resumed was interrupted by an IRQ,FIQ or SWI. The use of RFE here allows for exactly the same behaviour no matter which way the context record is saved and restored.

function ARMv8ThreadSetupStack(StackBase:Pointer; StartProc:TThreadStart; ReturnProc:TThreadEnd; Parameter:Pointer):Pointer;

Description: Set up the context record and arguments on the stack for a new thread

StackBase	Pointer to the base (highest address) of the allocated stack (as returned by ThreadAllocateStack
StartProc	The procedure the thread will start executing when resumed
ReturnProc	The procedure the thread will return to on exit
Return	Pointer to the starting address of the stack, which will be the Stack Pointer on the first context switch.
Note	At the point of a context switch the thread stack will look like this: (Base "Highest Address" of Stack) . . . . cpsr <- The current program status register value to load on return from the context switch (On Interrupt: Includes the flags and control bits for the interrupted thread) (On Yield: Includes the control bits only for the yielded thread) (On Create: Includes the control bits only for the new thread) lr/pc <- The address to return to from the context switch (On Interrupt: The location the thread was at before interrupt) (On Yield: The location to return to in SchedulerReschedule) (On Create: The location of StartProc for the new thread) lr <- The lr value prior to the context switch (On Interrupt: The value of lr before the thread was interrupted) (On Yield: The location to return to in SchedulerReschedule) (On Create: The location of ReturnProc for the new thread) r12 <- r11 <- r10 <- r9 <- r8 <- r7 <- r6 <- The value of these registers prior to the context switch r5 <- (On Interrupt: The values before the thread was interrupted) r4 <- (On Yield: The values on return to SchedulerReschedule) r3 <- (On Create: The values on entry to StartProc as set by ThreadSetupStack) r2 <- r1 <- r0 <- d15 <- d14 <- d13 <- d12 <- d11 <- d10 <- d9 <- d8 <- The value of these floating point registers prior to the context switch d7 <- (On Interrupt: The values before the thread was interrupted) d6 <- (On Yield: The values on return to SchedulerReschedule) d5 <- (On Create: The values on entry to StartProc as set by ThreadSetupStack) d4 <- d3 <- d2 <- d1 <- d0 <- fpscr <- The floating point FPSCR register fpexc <- The floating point FPEXC register (Current StackPointer points to here) . . . . (Top "Lowest Address" of Stack) On exit from a standard context switch as performed by SchedulerReschedule the first value (Highest Address) of lr is used by the RFE (Return From Exception) instruction to load the pc which also loads the saved cpsr value. On exit from an IRQ or FIQ context switch as performed by SchedulerSwitch the first value (Highest Address) of lr is used by the interrupt handler to return from the interrupt. A standard context switch uses r12 to save the cpsr value (and RFE to restore it). Because the standard context switch is called from a routine which will have saved the value of r12 (which is caller save in the ARM ABI) then we do not need to save the original value of r12. An IRQ or FIQ context switch uses the SRS (Store Return State) and RFE (Return From Exception) instructions to save and restore the cpsr value from the spsr value of either IRQ or FIQ mode.

Description: Handle an interrupt request IRQ from an interrupt source

[Expand]

procedure ARMv8FIQHandler; assembler; nostackframe;

Description: Handle a fast interrupt request FIQ from an interrupt source

Note	This routine is registered as the vector for FIQ requests in the vector table loaded during startup. At the end of each instruction the processor checks the FIQ line and if triggered it will lookup the vector in the vector table and jump to the routine listed. When the processor receives an FIQ it switches to FIQ mode, stores the address of the next instruction in the FIQ mode link register (lr_fiq) and saves the current program status register into the FIQ mode saved program status register (spsr_fiq). The FIQ handler first checks the spsr to determine if the task being interrupted is a normal thread or an exception or interrupt handler. The FIQ handler then saves the FIQ mode lr and spsr (which represent the location and state to return to) onto either the SYS mode or SVC mode stack using the srsdb (Store Return State Decrement Before) instruction depending on the value of spsr. The FIQ handler switches to SYS or SVC mode and saves all the neccessary registers for the return to the interrupted task before switching back to FIQ mode in order to process the interrupt request. Because we arrive here from an interrupt the task that was executing has no opportunity to save registers and will be unaware on return that it was interrupted. For this reason we must save all of the general purpose registers (r0 to r12) as well as the SYS mode link register (lr). We do not save the stack pointer (r13) because we use it to store the other registers and will return it to the correct value before we return from the FIQ handler. The program counter (r15) does not need to be saved as it now points to this code. To process the fast interrupt request the handler calls the DispatchFIQ function which will dispatch the interrupt to a registered handler for processing. The handler must clear the interrupt source before it returns or the fast interrupt will simply occur again immediately once reenabled. To return from the fast interrupt request the handler uses the rfeia (Return From Exception Increment After) instruction which will load the pc and cpsr from the stack of the current mode (SYS or SVC).

+'''Ultibo Platform Interface unit for ARMv8'''
 The ARMv8 does not support the SWP/SWPB instructions for syncronisation (Lock/Mutex/Semaphore etc) unless enabled.
