Hello, linux-i2c mailing list, We would like to know your comments on exporting I2C statistics including bus error count and NACK counts as sysfs attributes, similarly to [1]. We have been using the error counters exported to the debugfs by I2C bus drivers such as [2]. It might so happen that when other types of I2C bus drivers start to export those counters to debugfs, they might use different naming schemes so that that the daemon collecting I2C counters on a large number of machines would need to parse those counters using different ways for different bus drivers. We think it might be good to have a more stable way and naming scheme for the different bus drivers to report those error counts, perhaps a fields in i2c_adapter that are exported as sysfs attributes? Please let us know if there are any problems in this plan. Thanks!
