With this and since I know there is great interest about threshold stuff, I stuck bitbang-all-the-way and this threshold patch into stable. I just built it and confirmed the accels were not broken, I did not check threshold performance. > * This patch will break (the anyway non-working) acceleration wakeup > implementation.

Well it should get some now... if it's still shaky I think we need to look at Sean McNeil's patch for 2.6.26 because with that he got reliable performance. But I rather think with bitbang-all-the-way now only having one bunch of code touching the ports, and interrupt lockout protecting them, the only thing left is going to be edge interrupt vs level if there still is trouble. > * I'm slightly worried about the working hours for Andy, Werner and the > others, don't you have 40h weeks at Openmoko? :-) We're so busy we didn't find time for the heart attack yet. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkjzNvcACgkQOjLpvpq7dMpHRACfSz6lit+jt2GB+7lKzLUasjir zEwAn0t/zfkAcbPQMHNjmfSNAM5YWn3e =j9yo -----END PGP SIGNATURE-----
