In the next patch, we will use the irq_posted technique for another engine interrupt, rather than use two members for the atomic updates, we can use two bits of one instead. First, we need to update the breadcrumbs to use the new common engine->irq_posted. v2: Use set_bit() rather than __set_bit() to ensure atomicity with respect to other bits in the mask Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170124151805.26146-1-chris@chris-wilson.co.uk Reviewed-by: Mika Kuoppala <mika.kuoppala@intel.com> |
