+``-t MAX_ITERS [MAX_ITERS ...], --iter_max MAX_ITERS [MAX_ITERS ...]``
+ Specifies LDPC decoder operations maximum number of iterations for throughput
+ and bler tests. If not specified iter_max is set to 6.
+
+``-s SNR [SNR ...], --snr SNR [SNR ...]``
+ Specifies for LDPC decoder operations the SNR in dB used when generating LLRs
+ for bler tests. If not specified snr is set to 0 dB.
+
+Test Cases
+~~~~~~~~~~
+
+There are 7 main test cases that can be executed using testbbdev tool:
+
+* Sanity checks [-c unittest]
+ - Performs sanity checks on BBDEV interface, validating basic functionality
+
+* Validation tests [-c validation]
+ - Performs full operation of enqueue and dequeue
+ - Compares the dequeued data buffer with a expected values in the test
+ vector (TV) being used
+ - Fails if any dequeued value does not match the data in the TV
+
+* Offload Cost measurement [-c offload]
+ - Measures the CPU cycles consumed from the receipt of a user enqueue
+ until it is put on the device queue
+ - The test measures 4 metrics
+ (a) *SW Enq Offload Cost*: Software only enqueue offload cost, the cycle
+ counts and time (us) from the point the enqueue API is called until
+ the point the operation is put on the accelerator queue.
+ (b) *Acc Enq Offload Cost*: The cycle count and time (us) from the
+ point the operation is put on the accelerator queue until the return
+ from enqueue.
+ (c) *SW Deq Offload Cost*: Software dequeue cost, the cycle counts and
+ time (us) consumed to dequeue one operation.
+ (d) *Empty Queue Enq Offload Cost*: The cycle count and time (us)
+ consumed to dequeue from an empty queue.
+
+* Latency measurement [-c latency]
+ - Measures the time consumed from the first enqueue until the first
+ appearance of a dequeued result
+ - This measurement represents the full latency of a bbdev operation
+ (encode or decode) to execute
+
+* Poll-mode Throughput measurement [-c throughput]
+ - Performs full operation of enqueue and dequeue
+ - Executes in poll mode
+ - Measures the achieved throughput on a subset or all available CPU cores
+ - Dequeued data is not validated against expected values stored in TV
+ - Results are printed in million operations per second and million bits
+ per second
+
+* BLER measurement [-c bler]
+ - Performs full operation of enqueue and dequeue
+ - Measures the achieved throughput on a subset or all available CPU cores
+ - Computed BLER (Block Error Rate, ratio of blocks not decoded at a given
+ SNR) in % based on the total number of operations.
+
+* Interrupt-mode Throughput [-c interrupt]
+ - Similar to Throughput test case, but using interrupts. No polling.
