Please run the igt validation suit on your new driver, a bunch of collabora engineers are working hard to make it run on non-intel drivers too. Ping Tomeu and Robert Foss for more info on this please. Lucky for you I'm working on generic nonblocking support in the atomic helpers, patches are on the mailing list. > +}; > + > + > +static int hibmc_hw_config(struct hibmc_drm_device *hidev) > +{ > + unsigned int reg; > + > + /* On hardware reset, power mode 0 is default. */ > + hibmc_set_power_mode(hidev, HIBMC_PW_MODE_CTL_MODE_MODE0); > + > + /* Enable display power gate & LOCALMEM power gate*/ > + reg = readl(hidev->mmio + HIBMC_CURRENT_GATE); > + reg &= ~HIBMC_CURR_GATE_DISPLAY_MASK; > + reg &= ~HIBMC_CURR_GATE_LOCALMEM_MASK; > + reg |= HIBMC_CURR_GATE_DISPLAY(ON); > + reg |= HIBMC_CURR_GATE_LOCALMEM(ON); > + > + hibmc_set_current_gate(hidev, reg); > + > + /* Reset the memory controller.
