Subject: [PATCH 03/31] usb: usbssp: Add trace events used in driver
Date: Thu, 19 Jul 2018 18:57:36 +0100 [thread overview]
Message-ID: <1532023084-28083-4-git-send-email-pawell@cadence.com> (raw)
In-Reply-To: <1532023084-28083-1-git-send-email-pawell@cadence.com>
This patch creates a set of event class. For each event class this patch
defines some trace events.
1. event class: usbssp_log_msg
- usbssp_dbg_address - debug message used in function handling
Address Device Command.
- usbssp_dbg_context_change - debug messages related to contexti
updates performed with Configure Endpoint and Evaluate Contexti
command.
- usbssp_dbg_reset_ep - debug messages associated with resetting i
an endpoint.
- usbssp_dbg_cancel_request - debug messages related to the removal
of a cancelled Request.
- usbssp_dbg_init - debug messages related to the initialization
and unload.
- usbssp_dbg_ring_expansion - debug messages related to ring
expansion.
2. event class: usbssp_log_ctx
usbssp_address_ctx - debug message related to address Device command,
that can be used to display the context data filed.
3. event class: usbssp_log_trb
- usbssp_handle_event - debug message related to handling Events TRB.
- usbssp_handle_command - debug message related to handling C
ommand TRB.
- usbssp_handle_transfer - debug message related to handling
Transfer TRB.
- usbssp_queue_trb - debug message related to queuing TRB.
4. event class: usbssp_log_priv_dev
This class event tracing at least part of an usbssp_device lifetime,
and for now it already exposes quite a bit of valuable information.
- usbssp_alloc_priv_device - debug message related to allocating
device.
- usbssp_free_priv_device - debug message related to the freeing
device.
- usbssp_setup_addressable_priv_device - debug message related to the
initialization of usbssp_device object.
- usbssp_setup_device - debug message related to Address Device
command.
- usbssp_stop_device - debug message related to stooping device.
5. event class: usbssp_log_request
This will help us figuring out information related to usb_request
object.
- usbssp_request_enqueue - debug message used during enqueuing new
request.
- usbssp_request_giveback - debug message related to
usbssp_request_giveback function
- usbssp_request_dequeue - debug message related to dequeuing request.
- usbssp_alloc_request - debug message related to allocation
new request.
- usbssp_free_request - debug message related to freeing request.
6. event class: usbssp_log_ep_ctx
With these event class, we can track what's happening with the
HW while executing each and every command. It will give us visibility
into how the endpoint contexts are being modified by controller
which can bring insight into problems while debugging.
- usbssp_remove_request - debug message related to removing request.
- usbssp_handle_cmd_stop_ep - debug message related to Stop Endpointi
command.
- usbssp_handle_cmd_set_deq_ep - debug message releted to Set Dequeue
Endpoint command,
- usbssp_handle_cmd_reset_ep - debug message related to Reset Endpoint
command.
- usbssp_handle_cmd_config_ep - debug message related to Endpoint
Configure command.
7. event class: usbssp_log_slot_ctx
With these event class, we can track what's happening with the HW
while executing each and every command. It will give us visibility
into how the slot contexts are being modified by controller which
can bring insight into problems while debugging.
- usbssp_alloc_dev - debug message related to allocating device.
- usbssp_free_dev - debug message related to freeing device.
- usbssp_handle_cmd_disable_slot - debug message related to
Disable Slot command.
- usbssp_reset_device - debug message related to resetting device.
- usbssp_setup_device_slot - debug message related to c
onfiguring slot.
- usbssp_handle_cmd_addr_dev - debug message related to Address Device
command.
- usbssp_handle_cmd_reset_dev - debug message related to Reset Device
command.
- usbssp_handle_cmd_set_deq - debug message related to
Set Dequeue command.
- usbssp_configure_endpoint - debug message used during configuring
endpoints.
8. event class: usbssp_log_ring
This event class defines the events used for tracing the change
of all kinds of rings used by an usbssp device. An usbssp ring
is basically a memory block shared between software and hardware.
By tracing changes of rings, it makes the life easier for.
- debugging hardware or software problems.
- usbssp_ring_alloc - debug message related to allocation ring.
- usbssp_ring_free - debug message related to freeing ring.
- usbssp_ring_expansion - debug message related with expansion ring.
- usbssp_inc_enq - debug message related with incrementing
dequeue pointer.
- usbssp_inc_deq - debug message related with decrementing
dequeue pointer.
9. event class: usbssp_log_portsc
Track the port status each time we get a port status change event.
- usbssp_handle_port_status - debug message used in
handle_port_status function.
