It 35 * anticipates certain structures definitions. Those definitions are to be 36 * imported from global workspace. Instead of that, the structures needed for 37 * rc library are copied in to this file and exported to rc library. If the 38 * structures / enums / ... in the global workspace change, this file also needs 39 * to be modified accordingly. 40 * 41 ****************************************************************************** 42 */ 43 #ifndef IH264E_RC_MEM_INTERFACE_H_ 44 #define IH264E_RC_MEM_INTERFACE_H_ 45 46 47 /*****************************************************************************/ 48 /* Function Macros */ 49 /*****************************************************************************/ 50 51 #define FILL_MEMTAB(m_pv_mem_rec, m_j, m_mem_size, m_align, m_type) \ 52 { \ 53 m_pv_mem_rec[m_j].u4_size = sizeof(iv_mem_rec_t); \ 54 m_pv_mem_rec[m_j].u4_mem_size = m_mem_size; \ 55 m_pv_mem_rec[m_j].u4_mem_alignment = m_align; \ 56 m_pv_mem_rec[m_j].e_mem_type = m_type; \ 57 } 58 59 /*****************************************************************************/ 60 /* Enums */ 61 /*****************************************************************************/ 62 typedef enum 63 { 64 ALIGN_BYTE = 1, 65 ALIGN_WORD16 = 2, 66 ALIGN_WORD32 = 4, 67 ALIGN_WORD64 = 8, 68 ALIGN_128_BYTE = 128 69 }ITT_MEM_ALIGNMENT_TYPE_E; 70 71 typedef enum 72 { 73 SCRATCH = 0, 74 PERSISTENT = 1, 75 WRITEONCE = 2 76 }ITT_MEM_USAGE_TYPE_E; 77 78 typedef enum 79 { 80 L1D = 0, 81 SL2 = 1, 82 DDR = 3 83 }ITT_MEM_REGION_E; 84 85 typedef enum 86 { 87 GET_NUM_MEMTAB = 0, 88 FILL_MEMTAB = 1, 89 USE_BASE = 2, 90 FILL_BASE =3 91 }ITT_FUNC_TYPE_E; 92 93 94 /*****************************************************************************/ 95 /* Structures */ 96 /*****************************************************************************/ 97 98 /*NOTE : This should be an exact replica of IALG_MemRec, any change in IALG_MemRec 99 must be replicated here*/ 100 typedef struct 101 { 102 /* Size in bytes */ 103 UWORD32 u4_size; 104 105 /* Alignment in bytes */ 106 WORD32 i4_alignment; 107 108 /* decides which memory region to be placed */ 109 ITT_MEM_REGION_E e_mem_region; 110 111 /* memory is scratch or persistent */ 112 ITT_MEM_USAGE_TYPE_E e_usage; 113 114 /* Base pointer for allocated memory */ 115 void *pv_base; 116 } itt_memtab_t; 117 118 119 /*****************************************************************************/ 120 /* Extern Function Declarations */ 121 /*****************************************************************************/ 122 123 /** 124 ****************************************************************************** 125 * 126 * @brief This function fills memory record attributes 127 * 128 * @par Description 129 * This function fills memory record attributes 130 * 131 * @param[in] ps_mem_tab 132 * pointer to mem records 133 * 134 * @param[in] u4_size 135 * size of the record 136 * 137 * @param[in] i4_alignment 138 * memory alignment size 139 * 140 * @param[in] e_usage 141 * usage 142 * 143 * @param[in] e_mem_region 144 * mem region 145 * 146 * @return void 147 * 148 ****************************************************************************** 149 */ 150 void fill_memtab(itt_memtab_t *ps_mem_tab, WORD32 u4_size, WORD32 i4_alignment, 151 ITT_MEM_USAGE_TYPE_E e_usage, ITT_MEM_REGION_E e_mem_region); 152 153 /** 154 ****************************************************************************** 155 * 156 * @brief This function fills memory record attributes 157 * 158 * @par Description 159 * This function fills memory record attributes 160 * 161 * @param[in] ps_mem_tab 162 * pointer to mem records 163 * 164 * @param[in] ptr_to_be_filled 165 * handle to the memory record storage space 166 * 167 * @param[in] e_func_type 168 * enum that dictates fill memory records or use memory records 169 * 170 * @return void 171 * 172 ****************************************************************************** 173 */ 174 WORD32 use_or_fill_base(itt_memtab_t *ps_mem_tab, void **ptr_to_be_filled, 175 ITT_FUNC_TYPE_E e_func_type); 176 177 178 #endif // IH264E_RC_MEM_INTERFACE_H_ 179 180
