RapidIO provides 64 support for memory-mapped I/O as well as message-based 65 transactions over the switched fabric network. RapidIO has 66 a standardized discovery mechanism not unlike the PCI bus 67 standard that allows simple detection of devices in a 68 network. 69 </para> 70 <para> 71 This documentation is provided for developers intending 72 to support RapidIO on new architectures, write new drivers, 73 or to understand the subsystem internals. 74 </para> 75 </chapter> 76 77 <chapter id="bugs"> 78 <title>Known Bugs and Limitations</title> 79 80 <sect1 id="known_bugs"> 81 <title>Bugs</title> 82 <para>None. ;)</para> 83 </sect1> 84 <sect1 id="Limitations"> 85 <title>Limitations</title> 86 <para> 87 <orderedlist> 88 <listitem><para>Access/management of RapidIO memory regions is not supported</para></listitem> 89 <listitem><para>Multiple host enumeration is not supported</para></listitem> 90 </orderedlist> 91 </para> 92 </sect1> 93 </chapter> 94 95 <chapter id="drivers"> 96 <title>RapidIO driver interface</title> 97 <para> 98 Drivers are provided a set of calls in order 99 to interface with the subsystem to gather info 100 on devices, request/map memory region resources, 101 and manage mailboxes/doorbells. 102 </para> 103 <sect1 id="Functions"> 104 <title>Functions</title> 105!Iinclude/linux/rio_drv.h 106!Edrivers/rapidio/rio-driver.c 107!Edrivers/rapidio/rio.c 108 </sect1> 109 </chapter> 110 111 <chapter id="internals"> 112 <title>Internals</title> 113 114 <para> 115 This chapter contains the autogenerated documentation of the RapidIO 116 subsystem. 117 </para> 118 119 <sect1 id="Structures"><title>Structures</title> 120!Iinclude/linux/rio.h 121 </sect1> 122 <sect1 id="Enumeration_and_Discovery"><title>Enumeration and Discovery</title> 123!Idrivers/rapidio/rio-scan.c 124 </sect1> 125 <sect1 id="Driver_functionality"><title>Driver functionality</title> 126!Idrivers/rapidio/rio.c 127!Idrivers/rapidio/rio-access.c 128 </sect1> 129 <sect1 id="Device_model_support"><title>Device model support</title> 130!Idrivers/rapidio/rio-driver.c 131 </sect1> 132 <sect1 id="Sysfs_support"><title>Sysfs support</title> 133!Idrivers/rapidio/rio-sysfs.c 134 </sect1> 135 <sect1 id="PPC32_support"><title>PPC32 support</title> 136!Iarch/powerpc/sysdev/fsl_rio.c 137 </sect1> 138 </chapter> 139 140 <chapter id="credits"> 141 <title>Credits</title> 142 <para> 143 The following people have contributed to the RapidIO 144 subsystem directly or indirectly: 145 <orderedlist> 146 <listitem><para>Matt Porter<email>mporter@kernel.crashing.org</email></para></listitem> 147 <listitem><para>Randy Vinson<email>rvinson@mvista.com</email></para></listitem> 148 <listitem><para>Dan Malek<email>dan@embeddedalley.com</email></para></listitem> 149 </orderedlist> 150 </para> 151 <para> 152 The following people have contributed to this document: 153 <orderedlist> 154 <listitem><para>Matt Porter<email>mporter@kernel.crashing.org</email></para></listitem> 155 </orderedlist> 156 </para> 157 </chapter> 158</book> 159
