Re: [PATCH] drm/meson: Convert to Linux IRQ interfaces

Hi Thomas,

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's
IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers
don't benefit from using it.

-       ret = drm_irq_install(drm, priv->vsync_irq);
+       ret = request_irq(priv->vsync_irq, meson_irq, 0, drm->driver->name, drm);

I'd like to use dev_name(dev) instead of drm->driver->name in the
future as that'll make it much easier to identify the corresponding
IRQ in /proc/interrupts for example
your patch makes this possible - thanks for this!


Best regards,
Martin
