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.

7759 +
7760 +The CPMAC implementation will support 8 channels for transmit and 8 channel for
7761 +receive. Each of the 8 transmit channels has 1 queue associated with it. It is
7762 +recommended that only 1 channel is used for @c Receive() per processor.

7769 +- The Upper 16 bits of Mode match Word 3 of the Rx Buffer Descriptor
7770 +
7771 +@par halSend
7772 +@p Mode parameter
7773 +- Bits 0-7 contain the Channel Number

7778 +
7779 +@par StateChange
7780 +CPHAL calls the OS when a state change is detected.
7781 +OS should check the CPMAC Status. See the Control Key 'Status' for more details.
7782 +
7783 +@par Status
7784 +OS calls the CPHAL to obtain Status information. The Returned status is as follows
7785 +
7786 +@par MaxFrags
7787 +The OS may "Set" or "Get" this value. This defines the maximum
7788 +number of fragments that can be received by the CPMAC Rx port. The default
7789 +value for CPMAC is 2. This provides enough space to receive a maximum
7790 +length packet (1,518 bytes) with the default buffer size of 1518 and any
7791 +amount of RxBufferOffset. If the buffer size is configured to be smaller,
7792 +the OS *MUST* modify this parameter according to the following formula:
7793 +((System Max packet length)/(RxBufSize)) + 1. (The extra 1 fragment is to
7794 +allow for RxBufferOffset)
7795 +

12081 + * DESCRIPTION: Storing and retrieving the configuration based on key
12082 + * A set of APIs to be used by one and sundry (including drivers and enumerator) to build
12083 + * and read cfg information of the devices for an avalanche SOC.
12084 + *
12085 + * This set of APIs isolates the configuration management from the world and provides simple
12086 + * access convinience.
12087 + *
12088 + * Device in this set refers to the peripherals that can be found on the SOC or on VLYNQ.
12089 + * The configuration is stored in the form of string and drivers can use these APIs to get
12090 + * a particular parameter value.
12091 + *
12092 + * The memory allocation for the pass back parameters is done by the caller.
12093 + *
12094 + * 0 is returned for SUCCESS or TRUE.
12095 + * -1 is returned for FAILURE or FALSE.

12887 +Bug fixes: 1) A previous firmware upgrade caused firmware OAM loopback cells to only work on every other
12888 + command. This has been fixed in the new firmware version (0.47).
12889 + 2) Problem with PTI values changing on transparent mode packets has been resolved.

13002 +
13003 +New features: 1) AAL5 Send() modified to be capable of accepting ATM header as first four

13050 +
13051 +Bug fixes: 1) Fixed OAM logic in SAR portion of CPHAL.
13052 +
13053 +New features: 1) OAM loopback counters exposed through halControl.
13054 + 2) Host OAM Send() can now use a single channel to send
13055 + OAM cells on unlimited number of VP's/VC's.
13056 + 3) CPHAL now requests "SarFreq" through osControl.
13057 + 4) CPHAL now calculates all OAM function rates based on
13058 + "SarFreq"; function OamRateConfig removed for API.
13059 + 5) New OAM function OamLoopbackConfig, used for configuring
13060 + loopback functions in firmware OAM mode.
13061 +
13062 +Known issues not addressed in this release: Bug fix 1) in release 1.4
13063 + (see below) does not work properly for multiple fragments.

13068 + REL_20030410_HALdallas_cpsar_01.04.00
13069 +
13070 +This release is for SAR and MAC.
13071 +
13072 + Bug fixes: 1) Implemented logic in HAL to re-request buffer mallocs
13073 + in the case of MallocRxBuffer failing. The HAL now maintains
13074 + a NeedsBuffer queue of all RCB's that are without buffers.
13075 + On interrupts, or on Send(), the HAL checks to see if any
13076 + RCB's are on the queue, and if so, calls MallocRxBuffer
13077 + to attempt to get a new buffer and return the RCB to
13078 + circulation.
13079 + 2) SAR now properly returns all error codes from halOpen and
13080 + halChannelSetup.
13081 +
13082 + New features: NTR
13083 +
13084 + Known issues not addressed in this release: NTR

13086 +08 April 2003 CPHAL 1.3.1 (internal release - SAR only)
13087 +
13088 + CC Labels: REL_20030408_HALdallas_cpsar_01.03.01
13089 +
13090 + This is a SAR only release. The current CPMAC release is still 1.3.
13091 +
13092 + Bug fixes: 1) PDSP State RAM / Scratchpad RAM is now completely cleared after reset.
13093 + This resolves a stability issue.
13094 +
13095 + New features: 1) OamMode is now a parameter in halControl(). Both "Set" and "Get"
13096 + actions are available. The value may be "0" (Host OAM), or "1"
13097 + (Firmware OAM).
13098 +
13099 + Known issues not addressed in this release:
13100 + 1) Appropriate action for HAL in the case of MallocRxBuffer failing. We
13101 + are investigating whether the HAL should implement a needs buffer
13102 + queue.

13110 +
13111 + This release requires no changes for the ethernet end driver. The changes necessary
13112 + for the sar driver (firmware file name changes) have already been implemented.
13113 +
13114 + Bug fixes: 1) RxReturn now returns an error if MallocRxBuffer fails. On RxReturn error, the driver should
13115 + call RxReturn again at a later time (when the malloc may succeed) in order for the CPHAL
13116 + to maintain a full complement of Rx buffers. We recommend holding off making this driver
13117 + change until we verify that this condition occurs.
13118 +
13119 + New features: 1) Removed benign compiler warnings.
13120 + 2) PITS 122: http://www.nbu.sc.ti.com/cgi-bin/pits/redisplay_archive?product=cphal_dev&report=122
13121 + 3) Cpsar label (above) now is applied to everything
13122 + beneath /cpsar.
13123 + 4) PITS 14: http://www.nbu.sc.ti.com/cgi-bin/pits/redisplay_archive?product=cphal_dev&report=14
13124 + Transferred to MR PSP 00000089.
13125 + 5) PITS 120: http://www.nbu.sc.ti.com/cgi-bin/pits/redisplay_archive?product=cphal_dev&report=120
13126 +
13127 + Known issues not addressed in this release:
13128 + 1) PITS 102 (as relating to OamMode configuration):
13129 + http://www.nbu.sc.ti.com/cgi-bin/pits/redisplay_archive?product=cphal_dev&report=102
13130 + Future release will make OamMode configurable
13131 + through halControl(), not on per channel basis.
