+ * that on some OSs, certain flags can be completely ignored. We define a
+ * number of terms that are significant across all OSs:
+ *
+ * - Sleeping/non-sleeping mutexs. Sleeping mutexs can block on waiting, and so
+ * schedule out the current thread. This is significant on OSs where there are
+ * situations in which the current thread must not be put to sleep. On OSs
+ * without this restriction, sleeping and non-sleeping mutexes can be treated
+ * as the same (if that is required).
+ * - Interruptable/non-interruptable mutexes. For sleeping mutexes, it may be
+ * possible for the sleep to be interrupted for a reason other than the thread
+ * being able to obtain the lock. OSs behaving in this way may provide a
+ * mechanism to control whether sleeping mutexes can be interrupted. On OSs
+ * that do not support the concept of interruption, \b or they do not support
+ * control of mutex interruption, then interruptable mutexes may be treated
+ * as non-interruptable.
+ *
+ * Some constrains apply to the lock type flags:
+ *
+ * - Spinlocks are by nature, non-interruptable. Hence, they must always be
+ * combined with the NONINTERRUPTABLE flag, because it is meaningless to ask
+ * for a spinlock that is interruptable (and this highlights its
+ * non-interruptable-ness). For example, on certain OSs they should be used when
+ * you must not sleep.
+ * - Reader/writer is an optimization hint, and any type of lock can be
+ * reader/writer. Since this is an optimization hint, the implementation need
+ * not respect this for any/all types of lock. For example, on certain OSs,
+ * there's no interruptable reader/writer mutex. If such a thing were requested
+ * on that OS, the fact that interruptable was requested takes priority over the
+ * reader/writer-ness, because reader/writer-ness is not necessary for correct
+ * operation.
+ * - Any lock can use the order parameter.
+ * - A onelock is an optimization hint specific to certain OSs. It can be
+ * specified when it is known that only one lock will be held by the thread,
+ * and so can provide faster mutual exclusion. This can be safely ignored if
+ * such optimization is not required/present.
+ *
+ * The absence of any flags (the value 0) results in a sleeping-mutex, which is interruptable.

+/** @brief Cause a queued, deferred call of the IRQ bottom-half.
+ *
+ * _mali_osk_irq_schedulework provides a mechanism for enqueuing deferred calls
+ * to the IRQ bottom-half handler. The queue is known as the IRQ work-queue.
+ * After calling _mali_osk_irq_schedulework(), the IRQ bottom-half handler will
+ * be scheduled to run at some point in the future.
+ *
+ * This is called by the IRQ upper-half to defer further processing of
+ * IRQ-related work to the IRQ bottom-half handler. This is necessary for work
+ * that cannot be done in an IRQ context by the IRQ upper-half handler. Timer
+ * callbacks also use this mechanism, because they are treated as though they
+ * operate in an IRQ context. Refer to \ref _mali_osk_timer_t for more
+ * information.
+ *
+ * Code that operates in a kernel-process context (with no IRQ context
+ * restrictions) may also enqueue deferred calls to the IRQ bottom-half. The
+ * advantage over direct calling is that deferred calling allows the caller and
+ * IRQ bottom half to hold the same mutex, with a guarantee that they will not
+ * deadlock just by using this mechanism.
+ *
+ * _mali_osk_irq_schedulework() places deferred call requests on a queue, to
+ * allow for more than one thread to make a deferred call. Therfore, if it is
+ * called 'K' times, then the IRQ bottom-half will be scheduled 'K' times too.
+ * 'K' is a number that is implementation-specific.
+ *
+ * _mali_osk_irq_schedulework() is guaranteed to not block on:
+ * - enqueuing a deferred call request.
+ * - the completion of the IRQ bottom-half handler.
+ *
+ * This is to prevent deadlock. For example, if _mali_osk_irq_schedulework()
+ * blocked, then it would cause a deadlock when the following two conditions
+ * hold:
+ * - The IRQ bottom-half callback (of type _mali_osk_irq_bhandler_t) locks
+ * a mutex
+ * - And, at the same time, the caller of _mali_osk_irq_schedulework() also
+ * holds the same mutex
+ *
+ * @note care must be taken to not overflow the queue that
+ * _mali_osk_irq_schedulework() operates on. Code must be structured to
+ * ensure that the number of requests made to the queue is bounded. Otherwise,
+ * IRQs will be lost.
+ *
+ * The queue that _mali_osk_irq_schedulework implements is a FIFO of N-writer,
+ * 1-reader type. The writers are the callers of _mali_osk_irq_schedulework
+ * (all OSK-registered IRQ upper-half handlers in the system, watchdog timers,
+ * callers from a Kernel-process context). The reader is a single thread that
+ * handles all OSK-registered IRQs.
+ *
+ * The consequence of the queue being a 1-reader type is that calling
+ * _mali_osk_irq_schedulework() on different _mali_osk_irq_t objects causes
+ * their IRQ bottom-halves to be serialized, across all CPU-cores in the
+ * system.

+ * @addtogroup u_k_api UDD User/Kernel Interface (U/K) APIs
+ *
+ * - The _mali_uk functions are an abstraction of the interface to the device
+ * driver. On certain OSs, this would be implemented via the IOCTL interface.
+ * On other OSs, it could be via extension of some Device Driver Class, or
+ * direct function call for Bare metal/RTOSs.
+ * - It is important to note that:
+ *   -  The Device Driver has implemented the _mali_ukk set of functions
+ *   -  The Base Driver calls the corresponding set of _mali_uku functions.
+ * - What requires porting is solely the calling mechanism from User-side to
+ * Kernel-side, and propagating back the results.
+ * - Each U/K function is associated with a (group, number) pair from
+ * \ref _mali_uk_functions to make it possible for a common function in the
+ * Base Driver and Device Driver to route User/Kernel calls from/to the
+ * correct _mali_uk function. For example, in an IOCTL system, the IOCTL number
+ * would be formed based on the group and number assigned to the _mali_uk
+ * function, as listed in \ref _mali_uk_functions. On the user-side, each
+ * _mali_uku function would just make an IOCTL with the IOCTL-code being an
+ * encoded form of the (group, number) pair. On the kernel-side, the Device
+ * Driver's IOCTL handler decodes the IOCTL-code back into a (group, number)
+ * pair, and uses this to determine which corresponding _mali_ukk should be
+ * called.
+ *   - Refer to \ref _mali_uk_functions for more information about this
+ * (group, number) pairing.
+ * - In a system where there is no distinction between user and kernel-side,
+ * the U/K interface may be implemented as:@code
+ * MALI_STATIC_INLINE _mali_osk_errcode_t _mali_uku_examplefunction( _mali_uk_examplefunction_s *args )
+ * {
+ *     return mali_ukk_examplefunction( args );
+ * }
+ * @endcode
+ * - Therefore, all U/K calls behave \em as \em though they were direct
+ * function calls (but the \b implementation \em need \em not be a direct
+ * function calls)
+ *
+ * @note Naming the _mali_uk functions the same on both User and Kernel sides
+ * on non-RTOS systems causes debugging issues when setting breakpoints. In
+ * this case, it is not clear which function the breakpoint is put on.
+ * Therefore the _mali_uk functions in user space are prefixed with \c _mali_uku
+ * and in kernel space with \c _mali_ukk. The naming for the argument
+ * structures is unaffected.
+ *
+ * - The _mali_uk functions are synchronous.
+ * - Arguments to the _mali_uk functions are passed in a structure. The only
+ * parameter passed to the _mali_uk functions is a pointer to this structure.
+ * This first member of this structure, ctx, is a pointer to a context returned
+ * by _mali_uku_open(). For example:@code
+ * typedef struct
+ * {
+ *     void *ctx;
+ *     u32 number_of_cores;
+ * } _mali_uk_get_gp_number_of_cores_s;
+ * @endcode
+ *
+ * - Each _mali_uk function has its own argument structure named after the
+ *  function. The argument is distinguished by the _s suffix.
+ * - The argument types are defined by the base driver and user-kernel
+ *  interface.
+ * - All _mali_uk functions return a standard \ref _mali_osk_errcode_t.
+ * - Only arguments of type input or input/output need be initialized before
+ * calling a _mali_uk function.
+ * - Arguments of type output and input/output are only valid when the
+ * _mali_uk function returns \ref _MALI_OSK_ERR_OK.
+ * - The \c ctx member is always invalid after it has been used by a
+ * _mali_uk function, except for the context management functions
+ *
+ *
+ * \b Interface \b restrictions
+ *
+ * The requirements of the interface mean that an implementation of the
+ * User-kernel interface may do no 'real' work. For example, the following are
+ * illegal in the User-kernel implementation:
+ * - Calling functions necessary for operation on all systems,  which would
+ * not otherwise get called on RTOS systems.
+ *     - For example, a  U/K interface that calls multiple _mali_ukk functions
+ * during one particular U/K call. This could not be achieved by the same code
+ * which uses direct function calls for the U/K interface.
+ * -  Writing in values to the args members, when otherwise these members would
+ * not hold a useful value for a direct function call U/K interface.
+ *     - For example, U/K interface implementation that take NULL members in
+ * their arguments structure from the user side, but those members are
+ * replaced with non-NULL values in the kernel-side of the U/K interface
+ * implementation. A scratch area for writing data is one such example. In this
+ * case, a direct function call U/K interface would segfault, because no code
+ * would be present to replace the NULL pointer with a meaningful pointer.
+ *     - Note that we discourage the case where the U/K implementation changes
+ * a NULL argument member to non-NULL, and then the Device Driver code (outside
+ * of the U/K layer) re-checks this member for NULL, and corrects it when
+ * necessary. Whilst such code works even on direct function call U/K
+ * intefaces, it reduces the testing coverage of the Device Driver code. This
+ * is because we have no way of testing the NULL == value path on an OS
+ * implementation.
+ *
+ * A number of allowable examples exist where U/K interfaces do 'real' work:
+ * - The 'pointer switching' technique for \ref _mali_ukk_get_system_info
+ *     - In this case, without the pointer switching on direct function call
+ * U/K interface, the Device Driver code still sees the same thing: a pointer
+ * to which it can write memory. This is because such a system has no
+ * distinction between a user and kernel pointer.
+ * - Writing an OS-specific value into the ukk_private member for
+ * _mali_ukk_mem_mmap().
+ *     - In this case, this value is passed around by Device Driver code, but
+ * its actual value is never checked. Device Driver code simply passes it from
+ * the U/K layer to the OSK layer, where it can be acted upon. In this case,
+ * \em some OS implementations of the U/K (_mali_ukk_mem_mmap()) and OSK
+ * (_mali_osk_mem_mapregion_init()) functions will collaborate on the
+ *  meaning of ukk_private member. On other OSs, it may be unused by both
+ * U/K and OSK layers
+ *     - Therefore, on error inside the U/K interface implementation itself,
+ * it will be as though the _mali_ukk function itself had failed, and cleaned
+ * up after itself.
+ *     - Compare this to a direct function call U/K implementation, where all
+ * error cleanup is handled by the _mali_ukk function itself. The direct
+ * function call U/K interface implementation is automatically atomic.
+ *
+ * The last example highlights a consequence of all U/K interface
+ * implementations: they must be atomic with respect to the Device Driver code.
+ * And therefore, should Device Driver code succeed but the U/K implementation
+ * fail afterwards (but before return to user-space), then the U/K
+ * implementation must cause appropriate cleanup actions to preserve the
+ * atomicity of the interface.
+ *
+ * @{

+
+
+/** @defgroup _mali_uk_context U/K Context management
+ *
+ * These functions allow for initialisation of the user-kernel interface once per process.
+ *
+ * Generally the context will store the OS specific object to communicate with the kernel device driver and further
+ * state information required by the specific implementation. The context is shareable among all threads in the caller process.
+ *
+ * On IOCTL systems, this is likely to be a file descriptor as a result of opening the kernel device driver.
+ *
+ * On a bare-metal/RTOS system with no distinction between kernel and
+ * user-space, the U/K interface simply calls the _mali_ukk variant of the
+ * function by direct function call. In this case, the context returned is the
+ * mali_session_data from _mali_ukk_open().
+ *
+ * The kernel side implementations of the U/K interface expect the first member of the argument structure to
+ * be the context created by _mali_uku_open(). On some OS implementations, the meaning of this context
+ * will be different between user-side and kernel-side. In which case, the kernel-side will need to replace this context
+ * with the kernel-side equivalent, because user-side will not have access to kernel-side data. The context parameter
+ * in the argument structure therefore has to be of type input/output.
+ *
+ * It should be noted that the caller cannot reuse the \c ctx member of U/K
+ * argument structure after a U/K call, because it may be overwritten. Instead,
+ * the context handle must always be stored  elsewhere, and copied into
+ * the appropriate U/K argument structure for each user-side call to
+ * the U/K interface. This is not usually a problem, since U/K argument
+ * structures are usually placed on the stack.
