#87: flashrom issues on m57sli-s4 -------------------------+-------------------------------------------------- Reporter: ward | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: flashrom | Version: v2 Resolution: | Keywords: Dependencies: | Patchstatus: there is no patch -------------------------+-------------------------------------------------- Comment (by hailfinger):
For timing tests of flash readout, make sure CPU frequency scaling and power management are disabled. Then run
time flashrom -V --read test.rom; md5sum test.rom
on an idle system a few times in a row. If the "delay loops per second" value varies a lot, either the system is under load or CPU frequency scaling is active. If the md5sum is not constant, something fishy is going on.
The real/user/sys time needed for the command is what I'm interested in. The delay loop value is useless for LPC bus frequency measurement.
