-- FILE: V_VADS_EXEC.A
--
-- UNITS: VADS EXEC Package Specifications
--
-- PURPOSE: This file contains the user's high level interface to VADS EXEC.
-- It contains packages for each of the following services:
--
-- Interrupt Handling (package V_INTERRUPTS)
-- Tasking Extensions (package V_XTASKING)
-- Mutexes/CVs (package V_MUTEXES)
-- Semaphores (package V_SEMAPHORES)
-- Mailboxes (package V_MAILBOXES)
-- Memory Management (package V_MEMORY)
-- Stack Operations (package V_STACK)
-- Name Services (package V_NAMES)
--
-- The specifications for the above packages are contained in
-- this file. The bodies are located in the following files also
-- found in this directory:
-- V_INTERRUPTS v_intr_b.a
-- V_XTASKING v_xtask_b.a
-- V_MUTEXES v_mutexes_b.a
-- V_SEMAPHORES v_semaph_b.a
-- V_MAILBOXES v_mbox_b.a
-- V_MEMORY v_mem_b.a
-- V_STACK v_stack_b.a
-- V_NAMES v_name_b.a
--
-- These packages are layered upon the Ada Kernel. The Ada Kernel
-- provides all the threads and synchronization services needed
-- to implement the VADS EXEC services. The interface to the Ada
-- Kernel services is definied in the ADA_KRN_I package. Its type
-- definitions are provided in the ADA_KRN_DEFS package. Both
-- packages may be found in standard.
--
-- Do not modify or recompile these packages.

package V_Interrupts is
pragma Suppress (All_Checks);
-- PURPOSE : V_INTERRUPTS provides interrupt processing support
-- for the use of user-defined interrupt service
-- routines (ISR's), the getting/setting of interrupt status and
-- entering/leaving of supervisor state for the current task.
--
-- Refer to V_INTERRUPTS's machine dependent body in
-- V_INTR_B.A file for an outline of the actions that must
-- be performed in an ISR.
--
--
-- NOTES ON FLOATING-POINT COPROCESSOR SAVE/RESTORE IN ISR's:
--
-- A save/restore of the floating-point coprocessor state is
-- necessary if a coprocessor is in use and
-- floating-point objects might be used
-- during the execution of the interrupt handler. Note
-- that VADS_EXEC does not use floating-point
-- objects; thus, a coprocessor save/restore is not
-- necessary before calling the services.
--
-- NOTES ON DATA REFERENCES IN ISR's:
--
-- The user-defined interrupt handler must not reference
-- non-local stack-relative data (including tasks declared
-- within a subprogram). Instead, all references should
-- be either to objects declared in library-level
-- package specifications/bodies, in the interrupt
-- handler itself or in subprograms called by the handler.
--
-- NOTES ON EXCEPTION PROPAGATION IN ISR's:
--
-- Exceptions raised in an interrupt handler must be
-- handled locally. An "others" exception handler should
-- be provided to prevent attempting to propogate an
-- exception from an interrupt handler. If you don't provide
-- a handler for a raised exception (such as NUMERIC_ERROR),
-- then, the entire program is abandoned (just like an unhandled
-- exception for the main subprogram).
--
-- NOTES ON ISR/ADA TASK INTERACTION:
--
-- An ISR executes in the context of the task it interrupted.
-- Since the ISR does not have its own task state, it must
-- not perform any Ada tasking operations which would affect
-- the state of the interrupted task:
--
-- - task creations
-- - accept statements
-- - entry calls
-- - delay statements
-- - abort statements
-- - evaluation of an allocator or deallocator
--
-- In addition, the ISR cannot invoke any VADS_EXEC service which
-- might block:
--
-- - WAIT_SEMAPHORE
-- - READ_MAILBOX
-- - any V_MEMORY allocator or deallocator
--
-- If the ISR calls a service that would block, the
-- TASKING_ERROR exception is raised.
--
-- It may, however, invoke any non-blocking operation,
-- including:
--
-- - RESUME_TASK or SUSPEND_TASK
-- - SIGNAL_SEMAPHORE
-- - WRITE_MAILBOX
--
-- Floating-point registers do not have to be saved before
-- invoking VADS_EXEC services from an ISR.
--
-- The tasking and interrupt services support pre-emptive
-- task scheduling. If a call to a service from an
-- interrupt handler causes a task with a priority higher
-- than that of the interrupted task to become ready to run,
-- the higher priority task will run immediately upon return
-- from the outermost interrupt service routine.

generic
with procedure Interrupt_Handler;
procedure Isr;
pragma Share_Code (Isr, False);
-- Purpose: ISR provides the wrapper required for all
-- interrupt service routines. It may be instantiated
-- with a parameterless procedure which provides the
-- handler for a particular interrupt. The address
-- of the resulting instantiation should be passed to
-- ATTACH_ISR to attach the interrupt service routine
-- to a particular vector.
--
-- Notes: This wrapper doesn't save/restore the floating point
-- context.
--
-- This generic must be instantiated at the library
-- package level.
generic
with procedure Interrupt_Handler;
procedure Fast_Isr;
pragma Share_Code (Fast_Isr, False);
-- Purpose: Faster version of the above ISR wrapper. Refer
-- to V_INTERRUPTS's machine dependent body in
-- V_INTR_B.A file for additional restrictions imposed -- on the INTERRUPT_HANDLER procedure.
generic
with procedure Float_Handler;
procedure Float_Wrapper;
pragma Share_Code (Float_Wrapper, False);
-- Purpose: FLOAT_WRAPPER saves/restores the floating point state.
-- Before FLOAT_HANDLER is called, the floating point state
-- is reset and float exceptions are enabled according to
-- the FLOATING_POINT_CONTROL parameter in the kernel
-- program's configuration package (V_KRN_CONF).
-- See the body of this generic for further details.
--
-- The resultant instantiation is normally used as an input
-- procedure parameter to the above ISR generic.
function Attach_Isr (Vector : in Vector_Id; Isr : in System.Address)
return System.Address;
-- Purpose: To attach an interrupt service routine to a given
-- interrupt vector. It returns the previously attached
-- ISR.
-- Where:
--
-- vector specifies the interrupt vector number to which
-- the interrupt service routine is to be attached.
-- The vector number is the number, not address,
-- of the interrupt vector.
--
-- isr specifies the address of the interrupt service routine.
--
-- Exceptions:
--
-- INVALID_INTERRUPT_VECTOR is raised if the vector number is
-- out-of-range.
--
-- VECTOR_IN_USE is raised if an interrupt handler has already been
-- assigned to the vector.
procedure Attach_Isr (Vector : in Vector_Id; Isr : in System.Address);
-- Purpose: Provide backward compatibility by overloading
-- ATTACH_ISR with a procedure version that doesn't
-- return the previously attached vector.
function Detach_Isr (Vector : in Vector_Id) return System.Address;
-- Purpose: To detach an interrupt routine from a given
-- interrupt vector (the attachment may have been
-- performed during VADS kernel initialization if the vector
-- was given an initial value in the user's interrupt
-- vector table). Returns the previously attached ISR.
--
-- Where:
--
-- vector specifies the number of the interrupt vector
-- which is to be detach. The vector number is
-- the number, not address, of the interrupt vector.
--
-- Notes: The interrupt service routine V_DEFAULT_ISR
-- defined in the V_KRN_CONF package will
-- be attached to the vector.
--
-- Exceptions:
--
-- INVALID_INTERRUPT_VECTOR is raised if the vector number is
-- out-of-range.
procedure Detach_Isr (Vector : in Vector_Id);
-- Purpose: Provide backward compatibility by overloading
-- DETACH_ISR with a procedure version that doesn't
-- return the previously attached vector.
function Get_Isr (Vector : in Vector_Id) return System.Address;
-- Purpose: To return the address of the currently attached ISR
-- for the given interrupt vector.
-- Where:
--
-- vector specifies the interrupt vector number of the ISR.
--
-- Exceptions:
--
-- INVALID_INTERRUPT_VECTOR is raised if the vector number is
-- out-of-range.
function Get_Ivt return System.Address;
-- Purpose: To return the address of the current Interrupt
-- Vector Table (IVT). Normally, the IVT is an array
-- of ISR addresses. However, the IVT representation
-- is CPU dependent (for 386 cross, its the IDT).
-- Exceptions:
--
-- None.
function Current_Interrupt_Status return Interrupt_Status_T;
-- Purpose: To get the current CPU interrupt status (mask or priority
-- level).
function Set_Interrupt_Status
(New_Status : in Interrupt_Status_T) return Interrupt_Status_T;
-- Purpose: To set the interrupt status (mask or priority) to a
-- different setting. The previous interrupt status
-- is returned.
-- Where:
--
-- new_status specifies the new interrupt status setting.
function Current_Supervisor_State return Boolean;
-- Purpose: To get the supervisor/user state of the current task.
-- If the task is in supervisor state, returns TRUE.
procedure Enter_Supervisor_State;
-- Purpose: To enter supervisor state for the current task.
-- This allows subsequent execution of privilege
-- instructions.
procedure Leave_Supervisor_State;
-- Purpose: To leave supervisor state for the current task.
-- Subsequent execution of privilege instructions results
-- in a CPU exception.
function Set_Supervisor_State (New_State : in Boolean) return Boolean;
-- Purpose: To set the supervisor/user state for the current task
-- to a different setting. The previous state
-- is returned.
--
-- Where:
--
-- new_state TRUE selects supervisor state, FALSE selects user state.
