https://bugzilla.kernel.org/show_bug.cgi?id=82781 --- Comment #11 from Christian Birchinger <joker@xxxxxxxxxxxx> --- Simply doing this also works: ni_dpm.c: bool ni_dpm_vblank_too_short(struct radeon_device *rdev) { struct rv7xx_power_info *pi = rv770_get_pi(rdev); u32 vblank_time = r600_dpm_get_vblank_time(rdev); /* we never hit the non-gddr5 limit so disable it */ u32 switch_limit = pi->mem_gddr5 ? 450 : 0; return true; Adding a hardcoded true also disables mclk changes. which only leads to one conclusion: if (vblank_time <= switch_limit) return true; else return false; Somehow the values are not always 450 but i cannot see such a case in the printk debug. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
