Hi, On drivers using drm_fb_helper's in fb_ops it is not possible to change video mode, because of different var->pixclock evaluation: int drm_fb_helper_check_var(struct fb_var_screeninfo *var, struct fb_info *info) { [...] if (var->pixclock == -1 || !var->pixclock) return -EINVAL; [...] int drm_fb_helper_set_par(struct fb_info *info) { [...] if (var->pixclock != -1) { DRM_ERROR("PIXEL CLCOK SET\n"); return -EINVAL; } [...] One of these evaluations will fail regardless of pixclock value. P.S. check CLCOK spelling :) |
