If invalid values are passed as kernel module parameter, the default value will be selected.
|
||||
|
||||
17. Debufs directory will be created for port specific in debug path of kernel i.e. "/sys/kernel/debug" in x86 Linux platfrom.
|
||||
Under port specific debugfs directory (tc956x_port0_debug/tc956x_port1_debug), module specific files are created to get dump of debug information related to module.
|
||||
Example:
|
||||
config_stats --> Registers related to CONFIG module
|
||||
mac_stats --> Registers related to MAC block
|
||||
mtl_stats --> Registers related to MTL block
|
||||
dma_stats --> Registers related to DMA block
|
||||
m3_stats --> Debug information related to M3 Firmware
|
||||
interrupt_stats --> Registers related to MSI & INT blocks
|
||||
other_stats --> Information related to Driver & Firmware, TAMAP, Flexible Receiver Parser, mmc counters
|
||||
reg_dump --> Dumps all registers of MAC, MTL, DMA and CNFG modules
|
||||
|
||||
Information will be printed to "dmesg" console, when files related to specific module are invoked.
|
||||
|
||||
debugfs file can be invoked by using "cat" command.
|
||||
Example:
|
||||
cat /sys/kernel/debug/tc956x_port0_debug/config_stats
