For debugging many issues, a history of the

of what exactly was going on just before any

history will be collected only when the host
driver is run in debug mode (i.e. with the
config ATH10K_DEBUG enabled).
This should be disabled by default unless user specifically pokes some
debugfs
value to turn it on so that it does not impact performance.
Hi Ben,
This history is enabled only if the user compiles the kernel with
ATH10K_DEBUG.
Making it runtime, adds a lot of "if" conditions for this history record.
Do you suggest to add support to enable/disable it runtime even in
ATH10K_DEBUG ?
Thanks,
Ben
Add history for tracking the below events
- register read
- register write
- IRQ trigger
- IRQ Enable
- IRQ Disable
- NAPI poll
- CE service
- WMI cmd
- WMI event
- WMI tx completion
This will help in debugging any crash or any
improper behaviour.
