From 9b82f3e61758ed897200f0244b63a77c1791bcba Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 30 Oct 2008 08:12:58 +0000 Subject: powerpc/ps3: Replace the flip_ctl logic in ps3av and ps3fb by a mutex Introduce ps3_gpu_mutex to synchronizes GPU-related operations, like: - invoking the L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT command using the lv1_gpu_context_attribute() hypervisor call, - handling the PS3AV_CID_AVB_PARAM packet in the PS3 A/V Settings driver.
