* [LINUX] Manage Tiler Pinning for dce DRM buffersPradeep Venkatasubbarao2014-03-251-9/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Applications using dce_alloc/dce_free calls to manage memory, leaked memory because on non-closure of the created dmabuf fds. Additionally, all memory allocated from Tiler/DMM via DRM need to be explictly pinned to tiler using dce_buf_lock/dce_buf_unlock calls. Hence in the earlier implementation, every call to dce_alloc/free had to be followed by a lock/unlock call to pin/unpin it to tiler. In order, to insulate the applications from the internal details of DRM memory management and for ease of use of alloc and free calls, dce_alloc now takes care of creating the dmabuf and pinning it to tiler while dce_free takes care of tiler unpinning and closure of dmabuf fd. Applications can continue to use dce_alloc and dce_free calls as before thus maintiaining backward compatibility. On the other hand, since the same interfaces are used for multiple remote core targets, like IPU and DSP, MemHeader struture is upgraded to hold the core for which the block of memory belongs to, to keep track of the core. Hence all applications/Remote cores using this version of libdce should recompile with the new MemHeader for proper functioning.

* [GLP] Enable DMA Buf HandleSaurabh Bipin Chandra2013-08-301-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts all MmRpc_Pointer_Param call to MmRpc_OffsetPointer_Param to take care of MemHeader. This is not needed from a QNX perspective but is needed from a Linux perspective. There should no added latency is QNX due to this change as the rpmsg_rpc kernel path is still the same. This patch invokes memplugin_share() for the buffers allocated through DCE to get the corresponding DMA Buf Handles for GLP. For QNX, the return value is expected to be 0. For linux, the patch adds the logic for Single vs Multiplanar buffers. For linux, the memplugin_share() logic is modified to store and retireve the same dma_buf_fd rather than getting a dup() each time. These changes makes the following assumptions: 1. All the parameter buffers are allocated through DCE/MemPlugin. 2. The CLient passes Virtual pointers, rather than DMA Buf Handles to libdce for parameter buffers. 3. For IO Buffers, the client passes DMA Buf Handles and are not allocated using DCE/MemPlugin. This patch assumes MmRpc is exposing translation[i].base.

* [GLP] Libdce linux implementationSathishkumar2013-08-271-0/+87
make install & libdce.c issue fix 1. make install has been fixed. libdce.h will be installed in /usr/include, libdce.so files in /usr/lib and libdce.pc in /usr/lib/pkgconfig on using --prefix=/usr. By default the prefix is /usr/local. 2. init and deinit calls are removed from libdce.h 3. dce_set_fd and dce_get_fd calls are implemented in libdce.c 4. configure.ac checks for libmmrpc and makefile.am modified to link with libmmrpc. configure.ac and makefile.am modified 1. Codec_engine,xdctolls,framework_components,ipc,xdctools and xdaias paths needs to be exported. Configure.ac checks for the exported paths. 2. Makefile.am is modified to have the exported paths in the include directories list for the compiler. Modifications done after review 1. Comments added in memplugin_linux.c. White spaces removed manually and cleaned up libdce.c, memplugin.h. dce_priv.h is modified to have File and line number in the logs. linux/dce.h file is removed. Libdce modifications for linux Linux Specific libdce functionality added. 1. memplugin calls specific to linux are added in memplugin_linux.c 2. Error and debug logs implementation for linux in dce_priv.h 3. xll and wayland specific files are moved to linux folder Change-Id: Ib41e6a52d902376cdabbb939dee7585944720d92 Signed-off-by: Saurabh Bipin Chandra <a0131926@ti.com> Signed-off-by: Sathishkumar <x0203598@ti.com>
