Subject: Re: Parallella: bcrypt


I fixed bug in Epiphany bcrypt implementation and with Lukas's help, it is
integrated in JtR -
But there is still one problem. It passes test when using usleep(20000) for
waiting but it doesn't pass it when busy wait is used. Busy wait solution
works when there is only one load to epiphany. If the code is in a loop
than results aren't correct. In case of JtR, test fails on get_hash[0](1).
Attached code is bcrypt implementation outside JtR. It has the same
problem. When there is only one test vector it works. When it's in a loop
(like in attached code) it always returns correct output for first test
vectors. It seems like others are never sent to device. But when while loop
is substituted with usleep(20000) everything works fine.
Connected to that, Yaniv, are e_read() and e_write() synchronous?
And what happens if parameter in e_load_group() is false? How to start
execution on eCore, using e_start()?
