--- Comment #5 from Chris Wilson chris@chris-wilson.co.uk 2012-05-12 05:32:03 PDT --- Judging from the problem description, this is the 8xx pageflipping bug. Should be fixed in 3.5:
commit c2798b19bac2538393fc932bfbe59807a4734b3e Author: Chris Wilson chris@chris-wilson.co.uk Date: Sun Apr 22 21:13:57 2012 +0100
drm/i915: i8xx interrupt handler
gen2 hardware has some significant differences from the other interrupt routines that were glossed over and then forgotten about in the transition to KMS. Such as
- 16bit IIR - PendingFlip status bit
This patch reintroduces a handler specifically for gen2 for the purpose of handling pageflips correctly, simplifying code in the process.
v2: Also fixup ring get/put irq to only access 16bit registers (Daniel)
