While creating a new channel, ioctls are called in the below sequence: 1. GPU_IOCTL_OPEN_CHANNEL 2. AS_IOCTL_BIND_CHANNEL 3. TSG_IOCTL_BIND_CHANNEL_EX 4. CHANNEL_ALLOC_GPFIFO_EX 5. CHANNEL_ALLOC_OBJ_CTX. subctx pdbs and valid mask are programmed in the channel instance block in the channel ioctls AS_IOCTL_BIND_CHANNEL & CHANNEL_ALLOC_GPFIFO_EX. Programming them in the ioctl AS_IOCTL_BIND_CHANNEL is redundant. Remove related hal g->ops.mm.init_inst_block_for_subctxs. The hal init_inst_block will program context pdb and big page size. The hal init_inst_block_core will program context pdb, big page size and subctx 0 pdb. This is used by h/w units (fecs, pmu, hwpm, bar1, bar2, sec2, gsp, perfbuf etc.). For user channels, subctx pdbs are programmed as part of ramfc setup.
