TILER is a hardware block made by Texas Instruments. Its purpose is to organize video/image memory in a 2-dimensional fashion to limit memory bandwidth and facilitate 0 effort rotation and mirroring. The TILER driver facilitates allocating, freeing, as well as mapping 2D blocks (areas) in the TILER container(s). It also facilitates rotating and mirroring the allocated blocks or its rectangular subsections. List of pending items in proposed order: * Add area packing support (multiple blocks can reside in the same band/area) to optimize area use * Add group-ID support (to specify which blocks can reside together in the same area) * Add multiple search directions to TCM-SiTA * Add 1D block support (including adding 1D search algo to TCM-SiTA) * Optimize mutex handling (don.t hold mutex during memory allocation/mapping/cache flushing) * Add block reference counting, support for sharing blocks * Move all kernel-API-s to tiler-iface.c * Support orphaned block support (in preparation for process cleanup support) * Change block identification from physical address to key-ID pair (in preparation for user space support, and process security) * Add support for process security (blocks from separate processes never reside in the same band) * Support file interface (ioctl and mmap) * Support for buffers (ordered list of blocks that are mapped to userspace together, such as YUV420sp) * Support 1D user buffer mapping into TILER container * Support for block pre-reservation (to further optimize area use) David Sin (1): TILER-DMM: DMM-PAT driver for TI TILER Lajos Molnar (6): TILER-DMM: Container manager interface and utility definitons TILER-DMM: TILER Memory Manager interface and implementation TILER-DMM: TILER interface file and documentation TILER-DMM: Geometry and view manipulation functions.
