109 +/**
110 +@defgroup Common_Statistics Statistics
111 +
112 +A broad array of module statistics is available. Statistics values are accessed
113 +through the @c Control() interface of the CPHAL. There are 5 different levels
114 +of statistics, each of which correspond to a unique set of data. Furthermore,
115 +certain statistics data is indexed by using a channel number and Tx queue number.
116 +The following is a brief description of each statistics level, along with the
117 +indexes used for the level:
118 +
119 +- Level 0: Hardware Statistics (index with channel)
120 +- Level 1: CPHAL Software Statistics (channel, queue)
121 +- Level 2: CPHAL Flags (channel, queue)
122 +- Level 3: CPHAL Channel Configuration (channel)
123 +- Level 4: CPHAL General Configuration (no index)
124 +
125 +The caller requests statistics information by providing a Key string to the
126 +@c Control() API in the following format: "Stats;[Level #];[Ch #];[Queue #]".
127 +The only valid Action parameter for statistics usage is "Get".
128 +
129 +Code Examples:
130 +@code
131 +unsigned int *StatsData;
132 +
133 +# Get Level 0 stats for Channel 1
134 +HalFunc->Control(OsDev->HalDev, "Stats;0;1", "Get", &StatsData);
135 +
136 +# Get Level 2 stats for Channel 0, Queue 0
137 +HalFunc->Control(OsDev->HalDev, "Stats;2;0;0", "Get", &StatsData);
138 +
139 +# Get Level 4 stats
140 +HalFunc->Control(OsDev->HalDev, "Stats;4", "Get", &StatsData);
141 +@endcode
142 +
143 +The information returned in the Value parameter of @c Control() is an
144 +array of pointers to strings. The pointers are arranged in pairs.
145 +The first pointer is a pointer to a name string for a particular statistic.
146 +The next pointer is a pointer to a string containing the representation of
147 +the integer statistic value corresponding to the first pointer. This is followed
148 +by another pair of pointers, and so on, until a NULL pointer is encountered. The
149 +following is example code for processing the statistics data. Note that the OS
150 +is responsible for freeing the memory passed back through the Value parameter of
151 +@c Control().
152 +
153 +@code
154 +unsigned int *StatsData;
155 +
156 +# Get Level 0 stats for Channel 1
157 +HalFunc->Control(OsDev->HalDev, "Stats;0;1", "Get", &StatsData);
158 +
159 +# output Statistics data
160 +PrintStats(StatsData);
161 +
162 +# the upper layer is responsible for freeing stats info
163 +free(&StatsPtr);
164 +
165 +...
166 +
167 +void PrintStats(unsigned int *StatsPtr)
168 + {
169 + while(*StatsPtr)
170 + {
171 + printf("%20s:", (char *)*StatsPtr);
172 + StatsPtr++;
173 + printf("%11s\n", (char *)*StatsPtr);
174 + StatsPtr++;
175 + }
176 + MySioFlush();
177 + }
178 +@endcode
179 +
180 +Within each statistics level, there are several statistics defined. The statistics that
181 +are common to every CPPI module are listed below. In addition, each module may define
182 +extra statistics in each level, which will be documented within the module-specific
183 +documentation appendices.
184 +
185 +- Level 0 Statistics
186 + - All level 0 statistics are module-specific.
187 +- Level 1 Statistics (CPHAL Software Statistics)
188 + - DmaLenErrors: Incremented when the port DMA's more data than expected (per channel). (AAL5 Only)
189 + - TxMisQCnt: Incremented when host queues a packet for transmission as the port finishes
190 +transmitting the previous last packet in the queue (per channel and queue).
191 + - RxMisQCnt: Incremented when host queues adds buffers to a queue as the port finished the
192 +reception of the previous last packet in the queue (per channel).
193 + - TxEOQCnt: Number of times the port has reached the end of the transmit queue (per channel and queue).
194 + - RxEOQCnt: Number of times the port has reached the end of the receive queue (per channel).
195 + - RxPacketsServiced: Number of received packets (per channel).
196 + - TxPacketsServiced: Number of transmitted packets (per channel and queue).

198 + - TxMaxServiced: Maximum number of packets that the CPHAL transmit interrupt has serviced at a time (per channel and queue).
199 + - RxTotal: Total number of received packets, all channels.
200 + - TxTotal: Total number of transmitted packets, all channels and queues.
201 +- Level 2 Statistics (CPHAL Flags)
202 + - RcbPool: Pointer to receive descriptor pool (per channel).
203 + - RxActQueueCount: Number of buffers currently available for receive (per channel).
204 + - RxActQueueHead: Pointer to first buffer in receive queue (per channel).
205 + - RxActQueueTail: Pointer to last buffer in receive queue (per channel).
206 + - RxActive: 0 if inactive (no buffers available), or 1 if active (buffers available).
207 + - RcbStart: Pointer to block of receive descriptors.
208 + - RxTeardownPending: 1 if Rx teardown is pending but incomplete, 0 otherwise.
209 + - TcbPool: Pointer to transmit descriptor pool (per channel and queue).
210 + - TxActQueueCount: Number of buffers currently queued to be transmitted (per channel and queue).
211 + - TxActQueueHead: Pointer to first buffer in transmit queue (per channel and queue).
212 + - TxActQueueTail: Pointer to last buffer in transmit queue (per channel and queue).
213 + - TxActive: 0 if inactive (no buffers to send), or 1 if active (buffers queued to send).
214 + - TcbStart: Pointer to block of transmit descriptors.
215 + - TxTeardownPending: 1 if Tx teardown is pending but incomplete, 0 otherwise.
216 +- Level 3 Statistics (CPHAL Channel Configuration)
217 + - RxBufSize: Rx buffer size.
218 + - RxBufferOffset: Rx buffer offset.
219 + - RxNumBuffers: Number of Rx buffers.
220 + - RxServiceMax: Maximum number of receive packets to service at a time.
221 + - TxNumBuffers: Number of Tx buffer descriptors.
222 + - TxNumQueues: Number of Tx queues to use.
223 + - TxServiceMax: Maximum number of transmit packets to service at a time.
224 +- Level 4 Statistics (CPHAL General Configuration)
225 + - Base Address: Base address of the module.
226 + - Offset (VLYNQ): VLYNQ relative module offset.
227 + - Interrupt Line: Interrupt number.
228 + - Debug: Debug flag, 1 to enable debug.
229 + - Inst: Instance number.

7753 +@page cpmac_intro Introduction
7754 +
7755 +The CPMAC implementation will support 8 channels for transmit and 8 channel for
7756 +receive. Each of the 8 transmit channels has 1 queue associated with it. It is
7757 +recommended that only 1 channel is used for @c Receive() per processor.

7762 +@par osReceive
7763 +@p Mode parameter
7764 +- The Upper 16 bits of Mode match Word 3 of the Rx Buffer Descriptor
7765 +
7766 +@par halSend
7767 +@p Mode parameter
7768 +- Bits 0-7 contain the Channel Number

7772 +@section cpmac_keys Control Keys
7773 +
7774 +@par StateChange
7775 +CPHAL calls the OS when a state change is detected.
7776 +OS should check the CPMAC Status. See the Control Key 'Status' for more details.
7777 +
7778 +@par Status
7779 +OS calls the CPHAL to obtain Status information. The Returned status is as follows
7780 +
7781 +@par MaxFrags
7782 +The OS may "Set" or "Get" this value. This defines the maximum
7783 +number of fragments that can be received by the CPMAC Rx port. The default
7784 +value for CPMAC is 2. This provides enough space to receive a maximum
7785 +length packet (1,518 bytes) with the default buffer size of 1518 and any
7786 +amount of RxBufferOffset. If the buffer size is configured to be smaller,
7787 +the OS *MUST* modify this parameter according to the following formula:
7788 +((System Max packet length)/(RxBufSize)) + 1. (The extra 1 fragment is to
7789 +allow for RxBufferOffset)
7790 +

12076 + * DESCRIPTION: Storing and retrieving the configuration based on key
12077 + * A set of APIs to be used by one and sundry (including drivers and enumerator) to build
12078 + * and read cfg information of the devices for an avalanche SOC.
12079 + *
12080 + * This set of APIs isolates the configuration management from the world and provides simple
12081 + * access convinience.
12082 + *
12083 + * Device in this set refers to the peripherals that can be found on the SOC or on VLYNQ.
12084 + * The configuration is stored in the form of string and drivers can use these APIs to get
12085 + * a particular parameter value.
12086 + *
12087 + * The memory allocation for the pass back parameters is done by the caller.
12088 + *
12089 + * 0 is returned for SUCCESS or TRUE.
12090 + * -1 is returned for FAILURE or FALSE.

12882 +Bug fixes: 1) A previous firmware upgrade caused firmware OAM loopback cells to only work on every other
12883 + command. This has been fixed in the new firmware version (0.47).
12884 + 2) Problem with PTI values changing on transparent mode packets has been resolved.
12885 + 3) Previously, successful firmware OAM loopback cells waited 5 seconds before notifying the
12886 + OS of success, rather that notifying immediately. This has been resolved in firmware.
12887 + 4) PITS #148 (MAC and SAR), #149 (MAC) have been fixed.
12888 +
12889 +New features: 1) AAL5 HAL now capable of receiving unknown VCI/VPI cells on a single transparent channel.
12890 + See updated HAL document (AAL5 appendix) for implementation details.
12891 + 2) AAL5 HAL now allows OS to modify the OAM loopback timeout window. Previously, failed
12892 + OAM loopback attempts timed out after a nominal 5 seconds (based on the SAR frequency
12893 + provided by the OS). Now, the default is 5 seconds, but the OS may change the
12894 + value via halControl() to any integer number of milliseconds. See updated HAL document

12997 +
12998 +New features: 1) AAL5 Send() modified to be capable of accepting ATM header as first four

13001 + parameters.

13003 + in the first fragment (by itself). It also passes up the OS an indication
13004 + of what the received packet type was. For Host OAM and transparent mode

13052 + 4) CPHAL now calculates all OAM function rates based on
13053 + "SarFreq"; function OamRateConfig removed for API.
13054 + 5) New OAM function OamLoopbackConfig, used for configuring
13055 + loopback functions in firmware OAM mode.

13064 +
13065 +This release is for SAR and MAC.
13066 +
13067 + Bug fixes: 1) Implemented logic in HAL to re-request buffer mallocs
13068 + in the case of MallocRxBuffer failing. The HAL now maintains
13069 + a NeedsBuffer queue of all RCB's that are without buffers.
13070 + On interrupts, or on Send(), the HAL checks to see if any
13071 + RCB's are on the queue, and if so, calls MallocRxBuffer
13072 + to attempt to get a new buffer and return the RCB to
13073 + circulation.
13074 + 2) SAR now properly returns all error codes from halOpen and
13075 + halChannelSetup.

13082 +
13083 + CC Labels: REL_20030408_HALdallas_cpsar_01.03.01
13084 +
13085 + This is a SAR only release. The current CPMAC release is still 1.3.
13086 +
13087 + Bug fixes: 1) PDSP State RAM / Scratchpad RAM is now completely cleared after reset.
13088 + This resolves a stability issue.
13089 +
13090 + New features: 1) OamMode is now a parameter in halControl(). Both "Set" and "Get"
13091 + actions are available. The value may be "0" (Host OAM), or "1"
13092 + (Firmware OAM).
13093 +
13094 + Known issues not addressed in this release:
13095 + 1) Appropriate action for HAL in the case of MallocRxBuffer failing. We
13096 + are investigating whether the HAL should implement a needs buffer
13097 + queue.

13105 +
13106 + This release requires no changes for the ethernet end driver. The changes necessary
13107 + for the sar driver (firmware file name changes) have already been implemented.
13108 +
13109 + Bug fixes: 1) RxReturn now returns an error if MallocRxBuffer fails. On RxReturn error, the driver should
13110 + call RxReturn again at a later time (when the malloc may succeed) in order for the CPHAL
13111 + to maintain a full complement of Rx buffers. We recommend holding off making this driver
13112 + change until we verify that this condition occurs.
13113 +
13114 + New features: 1) Removed benign compiler warnings.
13115 + 2) PITS 122: http://www.nbu.sc.ti.com/cgi-bin/pits/redisplay_archive?product=cphal_dev&report=122
13116 + 3) Cpsar label (above) now is applied to everything
13117 + beneath /cpsar.
13118 + 4) PITS 14: http://www.nbu.sc.ti.com/cgi-bin/pits/redisplay_archive?product=cphal_dev&report=14

13125 + Future release will make OamMode configurable
13126 + through halControl(), not on per channel basis.
