Interpretation of SPI debug output

Hi,

 

Below is a captured log of the console output with SPI interface on
AT91SAM9261 (SPI1):

 

xfer c038fe24: len 2 tx c02eb3b5/202eb3b5 rx c02eb3b7/202eb3b7 imr 018

at73c213 spi1.3: DEactivate 58

atmel_spi atmel_spi.1: xfer complete: 2 bytes transferred

ASoC version 0.13.1

ALSA device list:

  #0: AT73C213

TCP cubic registered

NET: Registered protocol family 1

NET: Registered protocol family 17

 

 

Can anyone help to give a brief description on how to interpret the first
statement, especially "tx c02eb3b5/202eb3b5 rx c02eb3b7/202eb3b7" ?

 

Thanks in advance.

 

Best Regards.

 

Sim CK

Read the source ;-)

                dev_dbg(controller,
                        "  xfer %p: len %u tx %p/%08x rx %p/%08x\n",
                        xfer, xfer->len,
                        xfer->tx_buf, xfer->tx_dma,
                        xfer->rx_buf, xfer->rx_dma);

It's the virtual/physical addresses of the tx and rx buffers.
