Daniel J Blueman 498e720b96 drm/i915: Fix gen6 (SNB) missed BLT ring interrupts. ... The failure appeared in dmesg as: [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 35064155, at 35064155], missed IRQ? This works around that problem on by making the blitter command streamer write interrupt state to the Hardware Status Page when a MI_USER_INTERRUPT command is decoded, which appears to force the seqno out to memory before the interrupt happens. v1->v2: Moved to prior interrupt handler installation and RMW flags as per feedback. v2->v3: Removed RMW of flags (by anholt) Cc: stable@kernel.org Signed-off-by: Daniel J Blueman <daniel.blueman@gmail.com> Signed-off-by: Eric Anholt <eric@anholt.net> Tested-by: Chris Wilson <chris@chris-wilson.co.uk> [v1] Tested-by: Eric Anholt <eric@anholt.net> [v1,v3] (incidence of the bug with a testcase went from avg 2/1000 to 0/12651 in the latest test run (plus more for v1)) Tested-by: Kenneth Graunke <kenneth@whitecape.org> [v1] Tested-by: Robert Hooker <robert.hooker@canonical.com> [v1] Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=33394 Signed-off-by: Dave Airlie <airlied@redhat.com>		14 years ago
