This is lazy. + +- We probably want to have some support for debugfs files on crtc/connectors and + maybe other kms objects directly in core. There's even drm_print support in + the funcs for these objects to dump kms state, so it's all there. And then the + ->show() functions should obviously give you a pointer to the right object. + +- The drm_info_list stuff is centered on drm_minor instead of drm_device. For + anything we want to print drm_device (or maybe drm_file) is the right thing. + +- The drm_driver->debugfs_init hooks we have is just an artifact of the old + midlayered load sequence. DRM debugfs should work more like sysfs, where you + can create properties/files for an object anytime you want, and the core + takes care of publishing/unpuplishing all the files at register/unregister + time. Drivers shouldn't need to worry about these technicalities, and fixing + this (together with the drm_minor->drm_device move) would allow us to remove + debugfs_init. + +Contact: Daniel Vetter + Better Testing ============== |
