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.

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.

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. - */ -typedef enum -{ - _MALI_OSK_LOCKFLAG_SPINLOCK = 0x1, /**< Specifically, don't sleep on those architectures that require it */ - _MALI_OSK_LOCKFLAG_NONINTERRUPTABLE = 0x2, /**< The mutex cannot be interrupted, e.g. delivery of signals on those architectures where this is required */ - _MALI_OSK_LOCKFLAG_READERWRITER = 0x4, /**< Optimise for readers/writers */ - _MALI_OSK_LOCKFLAG_ORDERED = 0x8, /**< Use the order parameter; otherwise use automatic ordering */ - _MALI_OSK_LOCKFLAG_ONELOCK = 0x10, /**< Each thread can only hold one lock at a time */ - _MALI_OSK_LOCKFLAG_SPINLOCK_IRQ = 0x20, /**< IRQ version of spinlock */ - /** @enum _mali_osk_lock_flags_t - * - * Flags from 0x10000--0x80000000 are RESERVED for User-mode */ - -} _mali_osk_lock_flags_t; - -/** @brief Mutual Exclusion Lock Mode Optimization hint - * - * The lock mode is used to implement the read/write locking of locks specified - * as _MALI_OSK_LOCKFLAG_READERWRITER.

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.
