--- Comment #11 from Alexandre Demers <alexandre.f.dem...@gmail.com> --- Found what is wrong with the help of a few printk and by comparing to the code being replaced. All the logic is good (going through crtc, disabling them, waiting for vblank) BUT setting "tmp |= EVERGREEN_CRTC_DISP_READ_REQUEST_DISABLE;" is wrong. If I do as in the previous code by setting tmp = 0 and then continuing with: radeon_wait_for_vblank(rdev, i); WREG32(EVERGREEN_CRTC_CONTROL + crtc_offsets[i], tmp); everything works fine as before. What is expected from "tmp |= EVERGREEN_CRTC_DISP_READ_REQUEST_DISABLE;"? From what I read with printk, it is far from a 0 or a 1. Is this normal? -- You are receiving this mail because: You are the assignee for the bug.
