mtd-tests: flash_speed: fix error message in read_eraseblock()

2025-11-28T19:13:57+00:00

Replace 'write' with 'read' in the error message of the read_eraseblock() function to indicate the correct direction of the operation. Signed-off-by: Gabor Juhos Signed-off-by: David Oberhollenzer

mtd-tests: flash_speed: really skip destructive tests

2025-11-28T19:13:56+00:00

Although both the 'multi-block erase' and the 'read-while-write latency' tests are destructive, but those are executed irregardless of whether destructive mode is enabled or not. Change the code to skip these tests if the DESTRUCTIVE flag is not set to avoid unexpected behaviour. Signed-off-by: Gabor Juhos Signed-off-by: David Oberhollenzer

mtd-tests: flash_speed: Benchmark continuous reads

2024-10-08T06:15:00+00:00

Currently the read throuput test tries: - 1 page - 2 pages - 1 block (64 or more pages, usually) But it might be interesting to see how the speed gradually increases, eg. testing all number of pages from 1 to maybe 16, and then arbitrarilly 32 and 64. Let's add a -C parameter to enable this additional test. The 2-page read/write tests are also moved under this new option. Signed-off-by: Miquel Raynal Signed-off-by: David Oberhollenzer

mtd-tests: flash_speed: Drop read_eraseblock_by_page()

2024-10-08T06:14:57+00:00

The read_eraseblock_by_2pages() has been generalized so it became read_eraseblock_by_npages(), but there is no limitation (besides 0) regarding the number of pages. Hence, drop the _by_page() helper and replace it with the _by_npages(), using 'npages = 1'. Signed-off-by: Miquel Raynal Signed-off-by: David Oberhollenzer

mtd-tests: flash_speed: Generalize read_eraseblock_by_2pages()

2024-10-08T06:14:53+00:00

Right now there are only 2 pages that may be read continuously, but why not trying more? At least when the continuous feature is out, this type of benchmarking will be interesting. In order to facilitate later additions, lets make this helper more generic and accept a global 'npages' variable as parameter (because this function is called in a macro, it is simpler like that).

mtd-tests: flash_speed: Clarify the number of pages in each set while measuring

2024-10-08T06:14:50+00:00

So far speed calculations have only be done 1 page at a time or 2 pages at a time in a block; so basically all the block was always read because all blocks are multiple of 2. But in the future, if we want to extend the number of pages in a single read, the final number of pages actually read might be less than an erase block size, hence failing the throuput calculations. Make the number of pages in a set explicit. Signed-off-by: Miquel Raynal Signed-off-by: David Oberhollenzer

mtd-tests: flash_speed: Drop an apparently useless block

2024-10-08T06:14:46+00:00

I know no device without a multiple of 2 number of pages in each block. Even though it might be the case, it is clearly not a big deal and we don't really care about reading the last page, we are doing a speed benchmark; so as long as the throughput calculation knows how much data has been read it's fine. Eitherway, I don't think we ever have fallen in this block because we would read the content of two pages (so one past the block) and put it in a page-wide buffer, which would probably lead to an out-of-bound abort. Just drop the block. Signed-off-by: Miquel Raynal Signed-off-by: David Oberhollenzer

mtd-tests: nandbiterrs: Add support for testing continuous reads

2024-10-08T06:14:42+00:00

In order to trigger a continuous read, the user needs to request at least two pages at the same time. So far the tool would only read single pages, so let's extend its capabilities to test continuous read output when the -c option is passed.

mtd-tests: nandbiterrs: Store the chunks size in an intermediate variable

2024-10-08T06:14:39+00:00

'pagesize' is used for two purposes: - accessing the size of a page - getting the size of the test buffer, which happen to be the size of a page for now. Use an intermediate variable when getting the size of the test buffer, as we will later increase its size. Signed-off-by: Miquel Raynal Signed-off-by: David Oberhollenzer
