Greetings Daniel and others,
I am wondering if the code below has been tested on actual hardware:
if (!HAS_PCH_NOP(dev) && master_ctl & GEN8_DE_PCH_IRQ) {
/*
* FIXME(BDW): Assume for now that the new interrupt handling
* scheme also closed the SDE interrupt handling race we've seen
* on older pch-split platforms. But this needs testing.
*/
u32 pch_iir = I915_READ(SDEIIR);
if (pch_iir) {
I915_WRITE(SDEIIR, pch_iir);
ret = IRQ_HANDLED;
cpt_irq_handler(dev, pch_iir);
} else
DRM_ERROR("The master control interrupt lied (SDE)!\n");
}
If this code has been tested on actual hardware is there any breakages that need
fixing? In addition if this hasn't been tested this is just a friendly reminder
to do so :).
Thanks,
Nick
