mmc_test provides tests aimed at testing SD/MMC hosts. This patch adds performance tests. It is advantageous to have performance tests in a kernel module like mmc_test for the following reasons: - transfer times can be measured very accurately - arbitrarily large transfers are possible - the effect of contiguous vs scattered pages can be determined The new tests are: 23. Best-case read performance 24. Best-case write performance 25. Best-case read performance into scattered pages 26. Best-case write performance from scattered pages 27. Single read performance by transfer size 28. Single write performance by transfer size 29. Single trim performance by transfer size 30. Consecutive read performance by transfer size 31. Consecutive write performance by transfer size 32. Consecutive trim performance by transfer size Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Cc: <linux-mmc@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
