This patch adds following endpoints: 1. /eal/memseg_list_array The command displays the memseg list from which the memory has been allocated. Example: --> /eal/memseg_list_array {"/eal/memseg_list_array": [0, 1]} 2. /eal/memseg_list_info, The command outputs the memsegs, from which the memory is allocated, for the memseg_list given as input. Example: --> /eal/memseg_list_info,1 {"/eal/memseg_list_info": [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, \ 12, 13, 14, 15]} 3. /eal/memseg_info,, The command outputs the memseg information based on the memseg-list and the memseg-id given as input. Example: --> /eal/memseg_info,0,10 {"/eal/memseg_info": {"Memseg_list_index": 0, \ "Memseg_index": 10, "Memseg_list_len": 64, \ "Start_addr": "0x260000000", "End_addr": "0x280000000", \ "Size": 536870912}} --> /eal/memseg_info,1,15 {"/eal/memseg_info": {"Memseg_list_index": 1, \ "Memseg_index": 15, "Memseg_list_len": 64, \ "Start_addr": "0xb20000000", "End_addr": "0xb40000000", \ "Size": 536870912}} 4. /eal/element_list,,, The command outputs number of elements in a memseg based on the heap-id, memseg-list-id and memseg-id given as input. Example: --> /eal/element_list,0,0,63 {"/eal/element_list": {"Element_count": 52}} --> /eal/element_list,0,1,15 {"/eal/element_list": {"Element_count": 52}} 5. /eal/element_info,,,, \ , The command outputs element information like element start address, end address, to which memseg it belongs, element state, element size. User can give a range of elements to be printed. Example: --> /eal/element_info,0,1,15,1,2 {"/eal/element_info": {"element.1": {"msl_id": 1, \ "ms_id": 15, "memseg_start_addr": "0xb20000000", \ "memseg_end_addr": "0xb40000000", \ "element_start_addr": "0xb201fe680", \ "element_end_addr": "0xb20bfe700", \ "element_size": 10485888, "element_state": "Busy"}, \ "element.2": {"msl_id": 1, "ms_id": 15, \ "memseg_start_addr": "0xb20000000", \ "memseg_end_addr": "0xb40000000", \ "element_start_addr": "0xb20bfe700", \ "element_end_addr": "0xb215fe780", "element_size": 10485888, \ "element_state": "Busy"}, "Element_count": 2}} Signed-off-by: Amit Prakash Shukla --- v2: - Fixed compilation error related int-to-pointer-cast - Changes for code review suggestions v3: - Commit message changes - Renaming end-points - Changing input parameters to comma-seperated - Reverting telemetry output buffer size v4: - Patch-2 adds telemetry support to display system memory v5: - Removed command help related changes lib/eal/common/eal_common_memory.c | 447 ++++++++++++++++++++++++++++- 1 file changed, 442 insertions(+), 5 deletions(-) diff --git a/lib/eal/common/eal_common_memory.c b/lib/eal/common/eal_common_memory.c index 688dc615d7..6b863979e9 100644 --- a/lib/eal/common/eal_common_memory.c +++ b/lib/eal/common/eal_common_memory.c @@ -3,6 +3,7 @@ */ #include +#include #include #include #include @@ -26,6 +27,7 @@ #include "eal_memcfg.h" #include "eal_options.h" #include "malloc_heap.h" +#include "malloc_elem.h" /* * Try to mmap *size bytes in /dev/zero.
