[RFC 0/8] TI TILER-DMM driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

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)
