From Revision 63 to 44

63	Initial debian source package setup. Initial debian source package setup.	Dominique Lasserre	11 years ago
62	flashbench: use only one out of 12 erase blocks flashbench: use only one out of 12 erase blocks This helps with TLC memory when while guessing the erase block size, so that the guessed erase block start is at the start of the actual erase block. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	11 years ago
61	flashbench: fix Makefile flashbench: fix Makefile This avoids link errors that people have reported Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	11 years ago
60	Add a license file with GPLv2 Add a license file with GPLv2 Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	12 years ago
59	flashbench: start at multiple of erasesize for --open-au flashbench: start at multiple of erasesize for --open-au Apparently, 1.5 MB erase blocks or multiples of that are more common than I first thought, so automatically try to handle these by starting at a multiple of the erase blcok. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
58	flashbench: add --offset command line argument flashbench: add --offset command line argument This makes it easier to do the --open-au test case on drives whose erase block is not a power of two. Note that for those, you have to pass a blocksize that is also not a power of two, but a fraction of the erase size, e.g. flashbench --open-au --random --open-au-nr=6 \ --erasesize=$[3 * 1024 * 1024] \ --blocksize=$[24 * 1024] \ --offset=$[24 * 1024 * 1024] \ /dev/sde Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
57	flashbench: add try_open_au_oob flashbench: add try_open_au_oob This function is needed for certain USB sticks that use an odd erase block size (4128 KiB in one case). We will probably need this later, commit it as unused for now. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
56	flashbench: spread out --open-au test some more flashbench: spread out --open-au test some more Using every other erase block is bad when you have guessed the erase block size incorrectly. Better skip three for each one we test, to have a better chance of actually hitting separate erase blocks. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
55	flashbench: compute proper average flashbench: compute proper average We want to compute the bytes per second from the average of the times it takes to read many sectors, not compute the average of the throughput, which is somewhat different and less interesting. Also, use only one try for the --open-au test, instead of the maximum of three. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
54	flashbench: use lower number of samples in -a test flashbench: use lower number of samples in -a test Turns out a bit too much, and might hide some effects. Also, using something just below a power of two works better, so use 7 now. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
53	flashbench: fix time_to_ns for 32 bit systems flashbench: fix time_to_ns for 32 bit systems Incorrect type conversion results in potentially negative time values. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
52	flashbench: fix FAT benchmark flashbench: fix FAT benchmark Random needs to be applied to blocks in the segment, not the order of blocks. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
51	flashbench: extend README flashbench: extend README This adds an explanation about how to find the number of open segments/eraseblocks. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
50	flashbench: add README file flashbench: add README file This adds a little introductory file describing how to use flashbench. Needs more text still. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
49	Revert "flashbench: remove alignment tests" Revert "flashbench: remove alignment tests" This reverts commit eefa89baa9800a3904d4ada44a61132f299a6633. Actually, I still want this back. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
48	flashbench: move nr-of-aus-detection into its own function flashbench: move nr-of-aus-detection into its own function With this change, the program basically gets usable from the command line. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
47	flashbench: allow finding the FAT using CLI flashbench: allow finding the FAT using CLI Recompiling flashbench every time to run it with different arguments sucks, so allow the find-fat test to be run from the command line, with all necessary args for tuning. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
46	flashbench: remove alignment tests flashbench: remove alignment tests These turned out to be pretty useless, so I'll just remove them. If someone wants them back, they are still in the git history and we can write them in using our program language. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
45	flashbench: allow passing an erase block size flashbench: allow passing an erase block size This is currently unused, but will be used to simplify running the programmed tests. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
44	flashbench: make -verbose switch work with vm.c flashbench: make -verbose switch work with vm.c This has been annoying me for far too long, time to fix it. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	Arnd Bergmann	13 years ago
