The point with debugfs would be that we would need to start a “structure” in the framework that can get easily extended, which obviously would need more thought, so that a driver can easily expose additional data. So something along the lines of: /sys/kernel/debug/spi/<bus>/* /sys/kernel/debug/spi/<bus>/<device>/* And with the right api we could make it easily extendable (much more easily than with sysfs...) So what I would do I post a patch to expose those “basics” via sysfs and then a patch to expose the histogram and potentially more via debugfs. -- To unsubscribe from this list: send the line "unsubscribe linux-spi" in
