VxWorks 5.5 BSP Developer’s Guide SHARED_POINTERS Attribute This attribute is only a problem if the memory shared between the driver and the device was obtained using the cacheDmaMalloc( ) routine. Because this routine can invoke MMU or other special hardware services, the address of the provided memory can be a virtual address. The device, however, can deal only in physical addresses. In this case, use the CACHE_DMA_VIRT_TO_PHYS and CACHE_DMA_PHYS_TO_VIRT macros to convert between driver-viewed addresses and device-viewed addresses. 5.8.4 Additional Cache Library Hints Here are some additional hints for using the cache library: ■ ■ Before adding any cacheLib support to your driver, ensure that the driver works reliably with the data cache turned off. You will not experience cache coherency problems with the data cache disabled. When you begin to add cacheLib support, you can enable the data cache. Any changes to the driver’s reliability can then be attributed to cache issues. Ensure that the driver works with cacheLib support on a single target first, using target-specific knowledge to guide the strategy. When this has been achieved, you can then modify the driver’s cacheLib strategy for broader, target-independent support. 110
6 Components 6.1 Introduction Tornado 2.x introduces a new configuration method better suited to handling the increasing complexity of the VxWorks environment. This method uses Tornado 2.x’s graphical configuration tool, the project facility, to provide users with a view into the configurable world of VxWorks. The project facility workspace displays a hierarchically organized list of optional software components that can easily be configured into VxWorks using point-and-click technology. (For Tornado 2.x, downloadable applications do not use components.) For most users, this GUI-level view of the configurable system is enough to satisfy their development needs. However, the project facility includes an API and a language, the Component Description Language (CDL), that are used to define components, their parameters, their dependencies, and their relationships with other components. This chapter discusses how to use these building blocks, the API and the CDL, to create or modify the software components that, when selected, are configured into your VxWorks system image or application. Components are a high-level means of grouping code and configuration data into units of functionality, such as “message logging.” Bootable projects are collections of components, their configuration parameter values, and their build options. In Tornado 2.x, using the project facility is the only way to manipulate projects; in other words, projects cannot be configured from the command line. (For more information about how to use the project facility, see the Tornado User’s Guide: Projects.) The traditional approach for configuring VxWorks, based on configuration header files, has become less and less effective coping with the rapidly increasing complexity of the software. When VxWorks 5.0 was released, there were about 111
