Any "module" can ++ * register as an observer or notifier. The notion of "module" is abstract and ++ * can mean anything used to identify either an observer or notifier. Usually ++ * it will be a pointer to a data structure which contains some state, ie an ++ * object. ++ * ++ * Before any notifiers can be added, the global notification manager must be ++ * brought up with dwc_alloc_notification_manager(). ++ * dwc_free_notification_manager() will bring it down and free all resources. ++ * These would typically be called upon module load and unload. The ++ * notification manager is a single global instance that handles all registered ++ * observable modules and observers so this should be done only once. ++ * ++ * A module can be observable by using Notifications to publicize some general ++ * information about it's state or operation. It does not care who listens, or ++ * even if anyone listens, or what they do with the information. The observable ++ * modules do not need to know any information about it's observers or their ++ * interface, or their state or data. ++ * ++ * Any module can register to emit Notifications. It should publish a list of ++ * notifications that it can emit and their behavior, such as when they will get ++ * triggered, and what information will be provided to the observer. Then it ++ * should register itself as an observable module. See dwc_register_notifier(). ++ * ++ * Any module can observe any observable, registered module, provided it has a ++ * handle to the other module and knows what notifications to observe. See ++ * dwc_add_observer(). ++ * ++ * A function of type dwc_notifier_callback_t is called whenever a notification ++ * is triggered with one or more observers observing it. This function is ++ * called in it's own process so it may sleep or block if needed. It is ++ * guaranteed to be called sometime after the notification has occurred and will ++ * be called once per each time the notification is triggered. It will NOT be ++ * called in the same process context used to trigger the notification. ++ * ++ * @section Limitiations ++ * ++ * Keep in mind that Notifications that can be triggered in rapid sucession may ++ * schedule too many processes too handle. Be aware of this limitation when ++ * designing to use notifications, and only add notifications for appropriate ++ * observable information. ++ * ++ * Also Notification callbacks are not synchronous.

The WUDEV ++ * driver uses only these functions. In order to port the WUDEV driver, only ++ * the functions in this library need to be re-implemented, with the same ++ * behavior as documented here. ++ * ++ * The Common library consists of higher level functions, which rely only on ++ * calling the functions from the DWC Portability library. These common ++ * routines are shared across modules. Some of the common libraries need to be ++ * used directly by the driver programmer when porting WUDEV. Such as the ++ * parameter and notification libraries. ++ * ++ * @section low Portability Library OS Wrapper Functions ++ * ++ * Any function starting with DWC and in all CAPS is a low-level OS-wrapper that ++ * needs to be implemented when porting, for example DWC_MUTEX_ALLOC(). All of ++ * these functions are included in the dwc_os.h file. ++ * ++ * There are many functions here covering a wide array of OS services. Please ++ * see dwc_os.h for details, and implementation notes for each function. ++ * ++ * @section common Common Library Functions ++ * ++ * Any function starting with dwc and in all lowercase is a common library ++ * routine. These functions have a portable implementation and do not need to ++ * be reimplemented when porting. The common routines can be used by any ++ * driver, and some must be used by the end user to control the drivers. For ++ * example, you must use the Parameter common library in order to set the ++ * parameters in the WUDEV module. ++ * ++ * The common libraries consist of the following: ++ * ++ * - Connection Contexts - Used internally and can be used by end-user. See dwc_cc.h ++ * - Parameters - Used internally and can be used by end-user. See dwc_params.h ++ * - Notifications - Used internally and can be used by end-user. See dwc_notifier.h ++ * - Lists - Used internally and can be used by end-user. See dwc_list.h ++ * - Memory Debugging - Used internally and can be used by end-user. See dwc_os.h ++ * - Modpow - Used internally only. See dwc_modpow.h ++ * - DH - Used internally only. See dwc_dh.h ++ * - Crypto - Used internally only. See dwc_crypto.h ++ * ++ * ++ * @section prereq Prerequistes For dwc_os.h ++ * @subsection types Data Types ++ * ++ * The dwc_os.h file assumes that several low-level data types are pre defined for the ++ * compilation environment. These data types are: ++ * ++ * - uint8_t - unsigned 8-bit data type ++ * - int8_t - signed 8-bit data type ++ * - uint16_t - unsigned 16-bit data type ++ * - int16_t - signed 16-bit data type ++ * - uint32_t - unsigned 32-bit data type ++ * - int32_t - signed 32-bit data type ++ * - uint64_t - unsigned 64-bit data type ++ * - int64_t - signed 64-bit data type ++ * ++ * Ensure that these are defined before using dwc_os.h. The easiest way to do ++ * that is to modify the top of the file to include the appropriate header. ++ * This is already done for the Linux environment. If the DWC_LINUX macro is ++ * defined, the correct header will be added. A standard header is ++ * also used for environments where standard C headers are available. ++ * ++ * @subsection stdarg Variable Arguments ++ * ++ * Variable arguments are provided by a standard C header . it is ++ * available in Both the Linux and ANSI C enviornment. An equivalent must be ++ * provided in your enviornment in order to use dwc_os.h with the debug and ++ * tracing message functionality. ++ * ++ * @subsection thread Threading ++ * ++ * WUDEV Core must be run on an operating system that provides for multiple ++ * threads/processes. Threading can be implemented in many ways, even in ++ * embedded systems without an operating system. At the bare minimum, the ++ * system should be able to start any number of processes at any time to handle ++ * special work. It need not be a pre-emptive system. Process context can ++ * change upon a call to a blocking function. The hardware interrupt context ++ * that calls the module's ISR() function must be differentiable from process ++ * context, even if your processes are impemented via a hardware interrupt. ++ * Further locking mechanism between process must exist (or be implemented), and ++ * process context must have a way to disable interrupts for a period of time to ++ * lock them out. If all of this exists, the functions in dwc_os.h related to ++ * threading should be able to be implemented with the defined behavior. ++ * ++ */ +--- /dev/null ++++ b/drivers/usb/host/dwc_common_port/usb.h +@@ -0,0 +1,850 @@ ++/* ++ * Copyright (c) 1998 The NetBSD Foundation, Inc. ++ * All rights reserved. ++ * ++ * This code is derived from software contributed to The NetBSD Foundation ++ * by Lennart Augustsson (lennart@augustsson.net) at ++ * Carlstedt Research & Technology. ++ * ++ * Redistribution and use in source and binary forms, with or without ++ * modification, are permitted provided that the following conditions ++ * are met: ++ * 1.

The only exceptions ++ * are creation functions (which might fail due to lack of resources) and functions that ++ * might timeout or fail due to lack of space. Errors that might be reported by the underlying ++ * OS API (e.g. invalid mutex) are treated as a programming error, and are merely asserted on. ++ * ++ * \section thread_synch Threads and synchronisation ++ * ++ * \subsection thread Threads ++ * ++ * The thread API is somewhat different to that found in Nucleus. In particular, threads ++ * cannot just be destroyed at arbitrary times and nor can they merely exit. This is so ++ * that the same API can be implemented across all interesting platforms without too much ++ * difficulty. See vcos_thread.h for details. Thread attributes are configured via ++ * the VCOS_THREAD_ATTR_T structure, found in vcos_thread_attr.h. ++ * ++ * \subsection sema Semaphores ++ * ++ * Counted semaphores (c.f. Nucleus NU_SEMAPHORE) are created with VCOS_SEMAPHORE_T. ++ * Under ThreadX on VideoCore, semaphores are implemented using VideoCore spinlocks, and ++ * so are quite a lot faster than ordinary ThreadX semaphores. See vcos_semaphore.h. ++ * ++ * \subsection mtx Mutexes ++ * ++ * Mutexes are used for locking. Attempts to take a mutex twice, or to unlock it ++ * in a different thread to the one in which it was locked should be expected to fail. ++ * Mutexes are not re-entrant (see vcos_reentrant_mutex.h for a slightly slower ++ * re-entrant mutex). ++ * ++ * \subsection evflags Event flags ++ * ++ * Event flags (the ThreadX name - also known as event groups under Nucleus) provide ++ * 32 flags which can be waited on by multiple clients, and signalled by multiple clients. ++ * A timeout can be specified. See vcos_event_flags.h. An alternative to this is the ++ * VCOS_EVENT_T (see vcos_event.h) which is akin to the Win32 auto-reset event, or a ++ * saturating counted semaphore. ++ * ++ * \subsection event Events ++ * ++ * A VCOS_EVENT_T is a bit like a saturating semaphore. No matter how many times it ++ * is signalled, the waiter will only wake up once. See vcos_event.h. You might think this ++ * is useful if you suspect that the cost of reading the semaphore count (perhaps via a ++ * system call) is expensive on your platform. ++ * ++ * \subsection tls Thread local storage ++ * ++ * Thread local storage is supported using vcos_tls.h. This is emulated on Nucleus ++ * and ThreadX. ++ * ++ * \section int Interrupts ++ * ++ * The legacy LISR/HISR scheme found in Nucleus is supported via the legacy ISR API, ++ * which is also supported on ThreadX. New code should avoid this, and old code should ++ * be migrated away from it, since it is slow. See vcos_legacy_isr.h. ++ * ++ * Registering an interrupt handler, and disabling/restoring interrupts, is handled ++ * using the functions in vcos_isr.h. ++ * ++ */ ++ ++/** ++ * \file vcos.h ++ * ++ * This is the top level header file. Clients include this. It pulls in the platform-specific ++ * header file (vcos_platform.h) together with header files defining the expected APIs, such ++ * as vcos_mutex.h, vcos_semaphore.h, etc. It is also possible to include these header files ++ * directly. ++ * ++ */ ++ ++#ifndef VCOS_H ++#define VCOS_H ++ ++#include "interface/vcos/vcos_assert.h" ++#include "vcos_types.h" ++#include "vcos_platform.h" ++ ++#ifndef VCOS_INIT_H ++#include "interface/vcos/vcos_init.h" ++#endif ++ ++#ifndef VCOS_SEMAPHORE_H ++#include "interface/vcos/vcos_semaphore.h" ++#endif ++ ++#ifndef VCOS_THREAD_H ++#include "interface/vcos/vcos_thread.h" ++#endif ++ ++#ifndef VCOS_MUTEX_H ++#include "interface/vcos/vcos_mutex.h" ++#endif ++ ++#ifndef VCOS_MEM_H ++#include "interface/vcos/vcos_mem.h" ++#endif ++ ++#ifndef VCOS_LOGGING_H ++#include "interface/vcos/vcos_logging.h" ++#endif ++ ++#ifndef VCOS_STRING_H ++#include "interface/vcos/vcos_string.h" ++#endif ++ ++#ifndef VCOS_EVENT_H ++#include "interface/vcos/vcos_event.h" ++#endif ++ ++#ifndef VCOS_THREAD_ATTR_H ++#include "interface/vcos/vcos_thread_attr.h" ++#endif ++ ++#ifndef VCOS_TLS_H ++#include "interface/vcos/vcos_tls.h" ++#endif ++ ++#ifndef VCOS_REENTRANT_MUTEX_H ++#include "interface/vcos/vcos_reentrant_mutex.h" ++#endif ++ ++#ifndef VCOS_NAMED_SEMAPHORE_H ++#include "interface/vcos/vcos_named_semaphore.h" ++#endif ++ ++#ifndef VCOS_QUICKSLOW_MUTEX_H ++#include "interface/vcos/vcos_quickslow_mutex.h" ++#endif ++ ++/* Headers with predicates */ ++ ++#if VCOS_HAVE_EVENT_FLAGS ++#include "interface/vcos/vcos_event_flags.h" ++#endif ++ ++#if VCOS_HAVE_QUEUE ++#include "interface/vcos/vcos_queue.h" ++#endif ++ ++#if VCOS_HAVE_LEGACY_ISR ++#include "interface/vcos/vcos_legacy_isr.h" ++#endif ++ ++#if VCOS_HAVE_TIMER ++#include "interface/vcos/vcos_timer.h" ++#endif ++ ++#if VCOS_HAVE_MEMPOOL ++#include "interface/vcos/vcos_mempool.h" ++#endif ++ ++#if VCOS_HAVE_ISR ++#include "interface/vcos/vcos_isr.h" ++#endif ++ ++#if VCOS_HAVE_ATOMIC_FLAGS ++#include "interface/vcos/vcos_atomic_flags.h" ++#endif ++ ++#if VCOS_HAVE_ONCE ++#include "interface/vcos/vcos_once.h" ++#endif ++ ++#if VCOS_HAVE_BLOCK_POOL ++#include "interface/vcos/vcos_blockpool.h" ++#endif ++ ++#if VCOS_HAVE_FILE ++#include "interface/vcos/vcos_file.h" ++#endif ++ ++#if VCOS_HAVE_CFG ++#include "interface/vcos/vcos_cfg.h" ++#endif ++ ++#if VCOS_HAVE_CMD ++#include "interface/vcos/vcos_cmd.h" ++#endif ++ ++#endif /* VCOS_H */ ++ +--- /dev/null ++++ b/drivers/misc/vc04_services/interface/vcos/vcos_assert.h +@@ -0,0 +1,269 @@ ++/*============================================================================= ++Copyright (c) 2009 Broadcom Europe Limited. ++All rights reserved. ++ ++Project : vcfw ++Module : osal ++ ++FILE DESCRIPTION ++VideoCore OS Abstraction Layer - Assertion and error-handling macros. ++=============================================================================*/ ++ ++ ++#ifndef VCOS_ASSERT_H ++#define VCOS_ASSERT_H ++ ++/* ++ * Macro: ++ * vcos_assert(cond) ++ * vcos_assert_msg(cond, fmt, ...) ++ * Use: ++ * Detecting programming errors by ensuring that assumptions are correct. ++ * On failure: ++ * Performs a platform-dependent "breakpoint", usually with an assert-style ++ * message.
