* libdce[Android]: Add dce_ipc_recover APIAngela Stegmaier2017-01-171-0/+6
| | | | | | | | | | | | | | | | | In case of remote core recovery due to remote core crash, the rpmsg-dce handle needs to be closed and re-opened since any handles that were open when the crash happened are marked as stale in the driver. This patch adds a new API that the user can call to close the rpmsg-dce handle so that recovery can happen. In case the user receives notification of a remote core crash, it can call the dce_ipc_recover() API to make sure that the rpmsg-dce handle that is opened during dce_buf_lock is closed so that a new one can be opened the next time.

* get_rproc_info: Introduce new API to query remoteprocBuddy Liong2016-06-171-0/+15
| | | | | | | | | | | | | | | | | | | | | | This is the initial implementation of an extensible API that allows the user to query various remote core parameters. Currently, there are three query parameters that are supported: 1. CPU Load 2. Total configured heap size 3. Available heap size The intent of this API is to programmatically call the API and feed it in various other tools that can be developed on top of this (for example: soc performance visualization etc.) NOTE: This will require the implementation on ipumm-fw and/or dspdce-fw.

* libdce: Changes to make dce_ipc_init/deinit externalSunita Nadampalli2014-11-141-1/+15
| | | | | | | | | | dce_ipc_init and dce_ipc_deinit are required by android memplugin even before DCE engine open happens. This is required to use MmRpc interface for DRM/GEM buffer locking. Change-Id: Ia11af04658c367242c33ab8acffaa4b522aa0716 Signed-off-by: Sunita Nadampalli <sunitan@ti.com>
* [LINUX] Manage Tiler Pinning for dce DRM buffersPradeep Venkatasubbarao2014-03-251-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [DSP]Added duplicate functions for buffer lock and unlock.Pradeep Venkatasubbarao2013-12-061-2/+23
| | | | | | | | | | | | | | This is required temporarily as there is no other way to get the core index.dce_buf_lock and unlock functions expects MmRpcHandle and now as there are separate handles for DSP and IPU, to avoid modifying these APIs, duplicate functions have been created coreIndex is hardcoded.

| | | | | | | | | | | This patch adds VIDDEC2 interfaces and libdce now supports both VIDDEC2 and VIDDEC3 interfaces. It initializes ipc based on the server name(IVA or DSP).

* [LIBDCE] Replace Semaphore with MutexSunita Nadampalli2013-09-261-2/+1
| | | | | | | | | | | | | | | | | | | | | This patch reverts the below commit: "abd5152ca071e552954571862635666297221177 [LIBDCE] Mutual exclusion of Engine_open and Engine_close" Description: ----------- (1) The current semaphore logic doesn't protect the engine open/close calls across processes. It is confirmed on QNX that two instances of dce test app is creating two different instances of semaphore. Hence, other than the delay the current semaphore doesn't add any protection for the mutli process <-> multi instance scenarios. (2) For the single process <-> multi instance scenario, it does protect the engine open/close calls, but it fails due to lack of reference counting And also, it is not sure why we need to protect the entire engine_open/close. Hence the current semaphore is replaced with mutex to protect the ipc handle create/close. Change-Id: Ibdad089bdd39cd5afc813373e84bf91fa8920860 Signed-off-by: Sunita Nadampalli <sunitan@ti.com>
* [LINUX] Fix for make installSathishkumar2013-09-051-0/+1
| | | | | | | | | | | | This patch fixes make install. All the required headers are copied to $(includedir)/dce on make install. Unused variables(X11 and WAYLAND) are removed in Makefile.am and pkg-config on libmmrpc is removed as no libmmrpc.pc is available. xdc_target_types__=gnu/targets/std.h is added to libdce.h, so that applications need not do it when using libdce.h.

* [LIBDCE] Mutual exclusion of Engine_open and Engine_closeSaurabh Bipin Chandra2013-09-051-1/+2
| | | | | | | | | | | | | | | | This patch uses semaphores to mutually exclude: 1. dce_init() and Engine_open() IPU call. This solves a hang on IPU side during multiple instances. pthread mutex used within dce_init is replaced with semaphores as mutex is valid only across threads and not processes. 2. dce_deinit() and Engine_close(). This solves a hang on IPU side during multiple instances. Change-Id: Ia4d31582ebf0536142dee389e9601eae0169fb22 Signed-off-by: Saurabh Bipin Chandra <a0131926@ti.com>

* [LINUX] Expose dce_init and dce_deinit calls to userSaurabh Bipin Chandra2013-09-051-6/+25
| | | | | | | | | | | | | | | | | This patch changes the declaration of dce_init() and dce_deinit() to what is expected by Gstreamer for GLP and exposes it. This involves returning a struct omap_device pointer as void * during dce_init() and receiving a struct omap_device during dce_deinit(). The IPC initialization/deinitialization has been separated out of dce_init()/dce_deinit() into two static functions dce_ipc_init(), dce_ipc_deinit(). These functions are now included within Engine_open(), Engine_close() for all OSs. Change-Id: I86f4778cbd80f0a83aa3c39d8183bb3155a2a391 Signed-off-by: Saurabh Bipin Chandra <a0131926@ti.com>
* [LINUX] Expose API to lock and Unlock IO BuffersSaurabh Bipin Chandra2013-09-041-5/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch exposes APIs: dce_buf_lock(int num, size_t *handle) dce_buf_unlock(int num, size_t *handle) to lock and unlock the Input/Output Buffers respectively. The change is specific to GLP. The DRM driver pins and unpins tiler address for the IO Buffers whenever the rpmsg_rpc driver calls map_attachment and unmap_attachment() respectively. As the rpmsg_rpc driver invokes these calls during every process call, the reference buffer addresses (address of past locked buffers) held by the codec gets invalidated. That is, these addresses will not continue to map to the same memory region (YUV reference buffer) as before. Most often, these virtual addresses may point to the next YUV Buffer translated from the MPU. These APIs put a condition on the map and unmap() within rpmsg_rpc. The expectation from the application is to call dce_buf_lock() for the inArgs.inputID buffer and dce_buf_unlock() for the outArgs.freeBufID buffer.
