Disparity in Heap Needed for NVS Library Initialization

Postby squirtle321 » Mon Mar 25, 2024 4:58 pm

Using ESP-IDF v4.4.1

Referencing the note in the NVS Library documentation there's an overhead of 128 bytes to 640 bytes (https://docs.espressif.com/projects/esp ... -hash-list)

In practice I'm noticing a constant overhead of around 84 bytes per page + some constant overhead.

I'm invoking the heap tracing library to trace leaks, and then also tracking what the heap low water mark was before and after calling nvs_init.

Here's my test application:

Code: Select all

#include "esp_heap_trace.h"
#include "nvs.h"
#include "nvs_flash.h"
#define NUM_RECORDS 100
heap_trace_record_t trace_record[NUM_RECORDS];

void app_main(void)
{
    // Check initial heap low water mark
    multi_heap_info_t heap_info;
    heap_caps_get_info(&heap_info, MALLOC_CAP_DEFAULT);
    ESP_LOGI(TAG, "free heap1: %d", heap_info.total_free_bytes);

    // Start tracing library
    ESP_ERROR_CHECK( heap_trace_init_standalone(trace_record, NUM_RECORDS) );
    ESP_ERROR_CHECK( heap_trace_start(HEAP_TRACE_LEAKS) );
    
    // Check heap low water mark again
    heap_caps_get_info(&heap_info, MALLOC_CAP_DEFAULT);
    ESP_LOGI(TAG, "free heap2: %d", heap_info.total_free_bytes);
    
    // Invoke nvs_init
    nvs_flash_init();
    
    // Check heap low water mark again
    heap_caps_get_info(&heap_info, MALLOC_CAP_DEFAULT);
    ESP_LOGI(TAG, "free heap3: %d", heap_info.total_free_bytes);
    
    // Stop heap tracing, print results
    ESP_ERROR_CHECK( heap_trace_stop() );
    heap_trace_dump();
    
    // Check heap low water mark again
    heap_caps_get_info(&heap_info, MALLOC_CAP_DEFAULT);
    ESP_LOGI(TAG, "free heap4: %d", heap_info.total_free_bytes);

    for (int i=0; i<15; i++)
    {
        ESP_LOGI("main", "resting %d", i);
        vTaskDelay(1000);
    }
    
    esp_restart();
   }
I'm using two partition tables to compare, one partition table the NVS partition is size 0x40000, the other partition table has an NVS partition of size 0x160000.

Here is what I'm seeing:

Difference in Heap Low Water Mark Before and After NVS Init (NVS Size 0x160000) : 31072
Pages (NVS Size 0x160000) : 352
Heap per page (NVS Size 0x160000) : 88.27272727

Difference in Heap Low Water Mark Before and After NVS Init (NVS Size 0x40000) : 6880
Pages (NVS Size 0x40000) : 64
Heap per page (NVS Size 0x40000) : 107.5

Here's the heap tracing library output for Partition table size 0x160000

6556 bytes 'leaked' in trace (20 allocations)
total allocations 86 total frees 66
There's only one allocation that is different which is 29572 bytes and 5380 bytes for the respective partition table. This works out to around 84 bytes per page in either case.

Am I missing something here? Any help is appreciated.

Re: Disparity in Heap Needed for NVS Library Initialization

Postby ESP_rrtandler » Thu Mar 28, 2024 11:12 am

Hello squirtle321,

The RAM footprint of NVS after initialisation is comprised of 2 components:
  • Item Hash List (namespace, key, chunk index) - size depends on number of active key-value pairs
  • Page manager related footprint - size depends on NVS partition size
Run your statistics with various NVS partition sizes to get an idea of the RAM overhead to NVS partition size relationship. Scale your NVS partition sizes on multiples of page size (4096) bytes to get the best results.

Re: Disparity in Heap Needed for NVS Library Initialization

Hi squirtle321,

One more note. You may also try to run tests with the same NVS partition size and vary the number of different key - value pairs to see the influence of active data amount on the Key Hash Map heap overhead.

Start with empty NVS, make nvs_init and the heap overhead (nvs partition size dependent at this moment) will be related to the Page manager only. Create namespace and write 100 new different keys and observe the heap consumed. Delta heap space related to the active key-value pairs will be consumed during the writing of new keys (namespace is also key-value pair).

Reset the device and run nvs_init with namespace and 100 keys of data created by previous step already in NVS flash. The heap allocation will include both the Page manager (nvs partition size dependent) as well as Key Hash Map (number of active key-value pairs dependent) overheads.
