Currently there is a race condition in checking the pending_kickoff_cnt in wr_ptr_irq wait from display-thread and pp_done_irq from interrupt context. In both places, pending_kickoff_cnt is read first and modified later. In partial update cases where the frame-transfer is short, such a race condition might happen and would lead to both triggering the frame-done/release fence for the same frame. Fix it by combining read/modify to one statement in both places. Change-Id: I9162e7dc3f12af3590514f1ebfd68023aa920181 Signed-off-by: Veera Sundaram Sankaran <veeras@codeaurora.org>
