Hi list,
In June 2012 I started a discussion on moving the radeon PM info out from debugfs, into a proper place available to all, be it proc, sysfs, or some other way. For the rationale please see the archives: http://www.mail-archive.com/dri-devel@lists.freedesktop.org/msg23401.html
Jerome's reply at the time was that since big changes are coming, he didn't want to commit to any ABI at that time. DPM has now landed.
Jerome wanted to implement a custom ioctl for unprivileged apps to query the power details (and ideally other GPU info too). As now the big changes have happened, what's the status on this ioctl?
Pre-emptive -enopatch: I'm not the right person to design an ioctl, with exactly zero such experience in making kernel ABIs. I do volunteer to making the userspace app that displays the values and info.
