238 | 5) TODO: | 238 | 5) Debug Information |
239 | |||
240 | The driver exports many information i.e. internal statistics, | ||
241 | debug information, MAC and DMA registers etc. | ||
242 | |||
243 | These can be read in several ways depending on the | ||
244 | type of the information actually needed. | ||
245 | |||
246 | For example a user can be use the ethtool support | ||
247 | to get statistics: e.g. using: ethtool -S ethX | ||
248 | (that shows the Management counters (MMC) if supported) | ||
249 | or sees the MAC/DMA registers: e.g. using: ethtool -d ethX | ||
250 | |||
251 | Compiling the Kernel with CONFIG_DEBUG_FS and enabling the | ||
252 | STMMAC_DEBUG_FS option the driver will export the following | ||
253 | debugfs entries: | ||
254 | |||
255 | /sys/kernel/debug/stmmaceth/descriptors_status | ||
256 | To show the DMA TX/RX descriptor rings | ||
257 | |||
258 | Developer can also use the "debug" module parameter to get | ||
259 | further debug information. | ||
260 | |||
261 | In the end, there are other macros (that cannot be enabled | ||
262 | via menuconfig) to turn-on the RX/TX DMA debugging, | ||
263 | specific MAC core debug printk etc. Others to enable the | ||
264 | debug in the TX and RX processes. | ||
265 | All these are only useful during the developing stage | ||
266 | and should never enabled inside the code for general usage. | ||
267 | In fact, these can generate an huge amount of debug messages. | ||
