Subject: [Bug 82781] Option to disable mclk reclocking with AMD R9 280X (TAHITI) to avoid screen flickering on VGA/CRT

--- Comment #10 from Christian Birchinger <joker@netswarm.net> ---
I don't know why but the only way i can stop it from chaning mclk is doing
this:
si_dpm.c
/*
if ((rdev->pm.dpm.new_active_crtc_count > 1) ||
ni_dpm_vblank_too_short(rdev))
*/
disable_mclk_switching = true;
I know ni_dpm_vblank_too_short must report true because "450 <= 450".
I'm totaly clueless why only hardcoding "true" keeps mclk at max 160000
also any printk i add after this wont get printed out.
