usb: dwc3: debug: fix string position formatting mixup with ret and len

2020-02-10T19:13:50+00:00

Currently the string formatting is mixing up the offset of ret and len. Re-work the code to use just len, remove ret and use scnprintf instead of snprintf and len position accumulation where required. Remove the -ve return check since scnprintf never returns a failure -ve size. Also break overly long lines to clean up checkpatch warnings.

usb: dwc3: debug: Remove newline printout

2019-10-23T06:25:08+00:00

The newline from the unknown link state tracepoint doesn't follow the other tracepoints, and it looks unsightly. Let's remove it. Signed-off-by: Thinh Nguyen Signed-off-by: Felipe Balbi

usb: common: Separated decoding functions from dwc3 driver.

2019-08-29T07:52:27+00:00

Patch moves some decoding functions from driver/usb/dwc3/debug.h driver to driver/usb/common/debug.c file. These moved functions include: dwc3_decode_get_status dwc3_decode_set_clear_feature dwc3_decode_set_address dwc3_decode_get_set_descriptor dwc3_decode_get_configuration dwc3_decode_set_configuration dwc3_decode_get_intf dwc3_decode_set_intf dwc3_decode_synch_frame dwc3_decode_set_sel dwc3_decode_set_isoch_delay dwc3_decode_ctrl These functions are used also in inroduced cdns3 driver. All functions prefixes were changed from dwc3 to usb. Also, function's parameters has been extended according to the name of fields in standard SETUP packet. Additionally, patch adds usb_decode_ctrl function to include/linux/usb/ch9.h file. Signed-off-by: Pawel Laszczak Signed-off-by: Felipe Balbi

usb: dwc3: debug: Print GET_STATUS(device) tracepoint

2019-05-03T06:13:49+00:00

DWC3 is missing the printing of control request GET_STATUS(device) tracepoint. This patch prints that. Signed-off-by: Thinh Nguyen Signed-off-by: Felipe Balbi

usb: dwc3: debug: purge usage of strcat

2019-02-05T07:00:14+00:00

Now that buffer size is always passed around, we don't need to rely on strcat anymore. Signed-off-by: Felipe Balbi

usb: dwc3: trace: pass trace buffer size to decoding functions

2019-02-04T13:43:38+00:00

Instead of assuming that our buffer is big enough, let's pass the buffer size around so printing functions can make sure they won't overflow the buffer. Signed-off-by: Felipe Balbi

usb: dwc3: debugfs: Properly print/set link state for HS

2018-11-26T07:06:31+00:00

Highspeed device and below has different state names than superspeed and higher. Add proper checks and printouts of link states for highspeed and below. Signed-off-by: Thinh Nguyen Signed-off-by: Felipe Balbi

usb: dwc3: debug: decode uFrame from event too

2018-05-21T07:00:59+00:00

XferNotReady and XferInProgress give us the uFrame number we're currently in. Printing that out on tracepoints may help us find bugs in transfer scheduling. Signed-off-by: Felipe Balbi

usb: dwc3: trace: print out event status too

2018-05-21T07:00:56+00:00

This will make it easier to figure out the reason for the event. That information really helps debugging certain problems. Signed-off-by: Felipe Balbi

usb: dwc3: debug: decode a few more features
