--20cf307c9f1ca842bb04ac9bb7de Content-Type: text/plain; charset=ISO-8859-1 Hi Garrett, It looks like mfi(4) is missing a mask or several for the fw_status field when it tries to grab info about the battery backup. Maybe the attached patch can help a bit in figuring out what mfiutil is ignoring. I don't know if there's a publicly available datasheet for the firmware; I couldn't find it last time I tried. Maybe jhb@ has access to one. There's nothing useful in LSI's FreeBSD or Linux drivers - probably the opcodes and masks are just hardcoded into MegaCLI. If there's no way to figure out the masks from a datasheet, it'll probably be necessary to disassemble MegaCLI or something. I can try and figure it out, but I don't have access to a machine with an LSI controller right now, so it'd be tricky. =( Thanks, -Mark --20cf307c9f1ca842bb04ac9bb7de Content-Type: text/plain; charset=US-ASCII; name="mfiutil_debug.patch.txt" Content-Disposition: attachment; filename="mfiutil_debug.patch.txt" Content-Transfer-Encoding: base64 X-Attachment-Id: f_gsf0odhw0 ZGlmZiAtLWdpdCBhL3Vzci5zYmluL21maXV0aWwvbWZpX3Nob3cuYyBiL3Vzci5zYmluL21maXV0 aWwvbWZpX3Nob3cuYwppbmRleCA5ZDlmN2ExLi4wOWUxNGFhIDEwMDY0NAotLS0gYS91c3Iuc2Jp bi9tZml1dGlsL21maV9zaG93LmMKKysrIGIvdXNyLnNiaW4vbWZpdXRpbC9tZmlfc2hvdy5jCkBA IC0yMjAsNiArMjIwLDcgQEAgc2hvd19iYXR0ZXJ5KGludCBhYywgY2hhciAqKmF2KQogCWlmIChz dGF0LmZ3X3N0YXR1cyAmIE1GSV9CQlVfU1RBVEVfRElTQ0hBUkdFX0FDVElWRSkgewogCQlwcmlu dGYoIiVzIERJU0NIQVJHSU5HIiwgY29tbWEgPyAiLCIgOiAiIik7CiAJfQorCXByaW50ZigiZncg c3RhdHVzOiAleFxuIiwgc3RhdC5md19zdGF0dXMpOwogCWlmICghY29tbWEpCiAJCXByaW50Zigi IG5vcm1hbCIpOwogCXByaW50ZigiXG4iKTsK --20cf307c9f1ca842bb04ac9bb7de-- _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
