H A D | drm_drv.c | 6dc3e22e Wed Apr 20 11:45:03 CDT 2016 Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> drm: Make drm.debug parameter description more helpful
Let's be user-friendly and print an actually helpful parameter description.
This makes modinfo output the debug parameter like this:
parm: debug:Enable debug output, where each bit enables a debug category. Bit 0 (0x01) will enable CORE messages (drm core code) Bit 1 (0x02) will enable DRIVER messages (drm controller code) Bit 2 (0x04) will enable KMS messages (modesetting code) Bit 3 (0x08) will enable PRIME messages (prime code) Bit 4 (0x10) will enable ATOMIC messages (atomic code) Bit 5 (0x20) will enable VBL messages (vblank code) (int)
Changes from v1:
* Fixed s/PRMIE/PRIME typo. * Add ATOMIC and VBL debug parameter documentation. * Prefix the continuation lines with two tabs and removed the last new line. * Remove spurious whitespace.
