Hi, This is about a TV stick called MK808. Enabled VOP an HDMI for rk3066. Able to see pinguins at boot. Found similar bug reports for rk3399. http://lists.infradead.org/pipermail/linux-rockchip/2018-April/020426.html http://lists.infradead.org/pipermail/linux-rockchip/2018-April/020427.html http://lists.infradead.org/pipermail/linux-rockchip/2018-April/020428.html This patch doesn't seem to work for me. +++ b/drivers/gpu/drm/rockchip/rockchip_drm_vop.c @@ -1601,6 +1601,8 @@ static void vop_unbind(struct device *dev, struct device *master, void *data) { struct vop *vop = dev_get_drvdata(dev); + // Pair with the initial disable_irq() + enable_irq(vop->irq); Compared to rk3399 the rk3066 doesn't seem to have iommu.
