this looks like an issue recently reported by heiko, we found that might
due to an unbalanced irq disable in vop driver.
my test patch is:
+++ 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);
and i think sandy would send the real patch soon(maybe already sent?)
Works fine with your patch! Thank you very much Jeffy.
Best regards,
Jakob
