How significant is the cache maintenance over head?
Per,
Can you measure how much difference this has before and after your patch set please?
Absolutely, I can run the mmc_tests to get the measurement. The cache affect is greater the faster the flash memory is. Currently I only have access to a SD card (20 MiB/S). By the end of this week I can run on eMMC (45 MiB/s) if this will be needed.
Thanks for your input, Per
