All the parameters which need to be sent and received to/from IPU are coupled in a struct * allocated from Shared Memory. Only the adrress of the struct is passed to MmRpc * as a pointer argument. This approach is useful as MmRpc in some cases to avoid multiple * translations. * This approach is followed for : * Engine_open(), Engine_close(), create(), control(), delete() * For understanding refer to the Mmrpc_test.c in IPC 3.x * 2. All the parameters which need to be sent are given as separate arguments to * MmRpc. This appraoch is needed when you need to translate an address which is * ofsetted from a pointer which in itself needs to be translated. * This apporach is followed for : process() * For understanding, take the example of inbufs argument in process call(). Inbufs * allocated in Shared memory and needs to be translated, has the address of Input * buffer (allocated from Tiler). It is not possible to give the Input buffer as an argument * to Mmrpc for translation until inbufs is given as a parameter to Mmrpc. Therefore inbuf * can't be populated inside another Shared memory struct. * 3. This approach is a workaround to use approach [1] by solving the issue posed by [2]. * This approach is followed for : get_version() * Taking the example of inbufs to explain, the Input buffer address will be one of the * parameters of the struct (explained in [1]) along with inbufs address. Therefore the * Input buffer address will get translated here. At the IPU, this address needs to be * copied back to inbufs. ********************************************************************************* */ #include #include #include #include #include #include #if defined(BUILDOS_LINUX) #include #include #include #endif /* BUILDOS_LINUX */ /* IPC Headers */ #include /*DCE Headers */ #include "libdce.h" #include "dce_rpc.h" #include "dce_priv.h" #include "memplugin.h" #if defined(BUILDOS_LINUX) int fd = -1; #endif /* BUILDOS_LINUX */ /********************* GLOBALS ***********************/ /* Hande used for Remote Communication */ static MmRpc_Handle MmRpcHandle = NULL; static pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER; static int count = 0; /****************** INLINE FUNCTIONS ********************/ static inline void Fill_MmRpc_fxnCtx(MmRpc_FxnCtx *fxnCtx, int fxn_id, int num_params, int num_xlts, MmRpc_Xlt *xltAry) { fxnCtx->fxn_id = fxn_id; fxnCtx->num_params = num_params; fxnCtx->num_xlts = num_xlts; fxnCtx->xltAry = xltAry; } static inline void Fill_MmRpc_fxnCtx_OffPtr_Params(MmRpc_Param *mmrpc_params, int size, void *base, int offset, size_t handle) { mmrpc_params->type = MmRpc_ParamType_OffPtr; mmrpc_params->param.offPtr.size = (size_t)size; mmrpc_params->param.offPtr.base = (size_t)base; mmrpc_params->param.offPtr.offset = (size_t)offset; mmrpc_params->param.offPtr.handle = handle; } static inline void Fill_MmRpc_fxnCtx_Ptr_Params(MmRpc_Param *mmrpc_params, int size, void *addr, size_t handle) { mmrpc_params->type = MmRpc_ParamType_Ptr; mmrpc_params->param.ptr.size = size; mmrpc_params->param.ptr.addr = (size_t)addr; mmrpc_params->param.ptr.handle = handle; } static inline void Fill_MmRpc_fxnCtx_Scalar_Params(MmRpc_Param *mmrpc_params, int size, int data) { mmrpc_params->type = MmRpc_ParamType_Scalar; mmrpc_params->param.scalar.size = size; mmrpc_params->param.scalar.data = (size_t)data; } static inline void Fill_MmRpc_fxnCtx_Xlt_Array(MmRpc_Xlt *mmrpc_xlt, int index, int32_t base, int32_t addr, size_t handle) { /* index : index of params filled in FxnCtx */ /* offset : calculated from address of index */ mmrpc_xlt->index = index; mmrpc_xlt->offset = MmRpc_OFFSET(base, addr); mmrpc_xlt->base = handle; mmrpc_xlt->handle = handle; } /************************ FUNCTIONS **************************/ /* Interface for QNX for parameter buffer allocation */ /* These interfaces are implemented to maintain Backward Compatability */ void *dce_alloc(int sz) { return (memplugin_alloc(sz, 0, TILER_1D_BUFFER)); } void dce_free(void *ptr) { memplugin_free(ptr, TILER_1D_BUFFER); } /***************** FUNCTIONS SPECIFIC TO LINUX *******************/ #if defined(BUILDOS_LINUX) void *dce_init(void) { struct omap_device *OmapDev = NULL; dce_error_status eError = DCE_EOK; printf(" >> dce_init\n"); /* Open omapdrm device */ if( fd == -1 ) { printf("Open omapdrm device \n"); fd = drmOpen("omapdrm", "platform:omapdrm:00"); } if( fd >= 0 ) { OmapDev = omap_device_new(fd); } else { printf("Error opening omapdrm : drmOpen failed"); goto EXIT; } EXIT: return ((void *)OmapDev); } void dce_deinit(void *dev) { omap_device_del(dev); dev = NULL; close(fd); fd = -1; return; } int dce_buf_lock(int num, size_t *handle) { int i; MmRpc_BufDesc *desc = NULL; dce_error_status eError = DCE_EOK; _ASSERT(num > 0, DCE_EINVALID_INPUT); desc = memplugin_alloc(num * sizeof(MmRpc_BufDesc), 0, TILER_1D_BUFFER); _ASSERT(desc != NULL, DCE_EOUT_OF_MEMORY); for( i = 0; i < num; i++ ) { desc[i].handle = handle[i]; } eError = MmRpc_use(MmRpcHandle, MmRpc_BufType_Handle, num, desc); _ASSERT(eError == DCE_EOK, DCE_EIPC_CALL_FAIL); EXIT: return (eError); } int dce_buf_unlock(int num, size_t *handle) { int i; MmRpc_BufDesc *desc = NULL; dce_error_status eError = DCE_EOK; _ASSERT(num > 0, DCE_EINVALID_INPUT); desc = memplugin_alloc(num * sizeof(MmRpc_BufDesc), 0, TILER_1D_BUFFER); _ASSERT(desc != NULL, DCE_EOUT_OF_MEMORY); for( i = 0; i < num; i++ ) { desc[i].handle = handle[i]; } eError = MmRpc_release(MmRpcHandle, MmRpc_BufType_Handle, num, desc); _ASSERT(eError == DCE_EOK, DCE_EIPC_CALL_FAIL); EXIT: return (eError); } /* Incase of X11 or Wayland the fd can be shared to libdce using this call */ void dce_set_fd(int dce_fd) { fd = dce_fd; } int dce_get_fd(void) { return (fd); } #endif /* BUILDOS_LINUX */ /*=====================================================================================*/ /** dce_ipc_init : Initialize MmRpc.
