--0016e64f4a68c9b04f0467a0fcf0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit hello, would anyone object to the small attached atkbd(4) patch? the idea is to basically prevent atkbd(4) interrupt handler from calling keyboard callback function when polled mode is enabled. i would really like to hear from people who is using kbdmux(4) on smp systems and having problems with duplicated/missing characters while using keyboard at mountroot, geli, etc. prompts. basically, when low level console input functions (cngetc(), gets(), etc.) are used _and_ interrupts are enabled. thanks, max --0016e64f4a68c9b04f0467a0fcf0 Content-Type: text/plain; charset=US-ASCII; name="atkbd.c.diff.txt" Content-Disposition: attachment; filename="atkbd.c.diff.txt" Content-Transfer-Encoding: base64 X-Attachment-Id: f_ftkp63940 SW5kZXg6IGF0a2JkLmMKPT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PQotLS0gYXRrYmQuYwkocmV2aXNpb24gMTkxMDEyKQor KysgYXRrYmQuYwkod29ya2luZyBjb3B5KQpAQCAtNDc2LDcgKzQ3Niw3IEBACiBzdGF0aWMgaW50 CiBhdGtiZF9pbnRyKGtleWJvYXJkX3QgKmtiZCwgdm9pZCAqYXJnKQogewotCWF0a2JkX3N0YXRl X3QgKnN0YXRlOworCWF0a2JkX3N0YXRlX3QgKnN0YXRlID0gKGF0a2JkX3N0YXRlX3QgKilrYmQt PmtiX2RhdGE7CiAJaW50IGRlbGF5WzJdOwogCWludCBjOwogCkBAIC00ODUsNyArNDg1LDYgQEAK IAkJICogVGhlIGtleWJvYXJkIHdhcyBub3QgZGV0ZWN0ZWQgYmVmb3JlOwogCQkgKiBpdCBtdXN0 IGhhdmUgYmVlbiByZWNvbm5lY3RlZCEKIAkJICovCi0JCXN0YXRlID0gKGF0a2JkX3N0YXRlX3Qg KilrYmQtPmtiX2RhdGE7CiAJCWluaXRfa2V5Ym9hcmQoc3RhdGUtPmtiZGMsICZrYmQtPmtiX3R5 cGUsCiAJCQkgICAgICBrYmQtPmtiX2NvbmZpZyk7CiAJCUtCRF9GT1VORF9ERVZJQ0Uoa2JkKTsK QEAgLTQ5Niw2ICs0OTUsOSBAQAogCQlhdGtiZF9pb2N0bChrYmQsIEtEU0VUUkVQRUFULCAoY2Fk ZHJfdClkZWxheSk7CiAJfQogCisJaWYgKHN0YXRlLT5rc19wb2xsaW5nKQorCQlyZXR1cm4gMDsK KwogCWlmIChLQkRfSVNfQUNUSVZFKGtiZCkgJiYgS0JEX0lTX0JVU1koa2JkKSkgewogCQkvKiBs ZXQgdGhlIGNhbGxiYWNrIGZ1bmN0aW9uIHRvIHByb2Nlc3MgdGhlIGlucHV0ICovCiAJCSgqa2Jk LT5rYl9jYWxsYmFjay5rY19mdW5jKShrYmQsIEtCRElPX0tFWUlOUFVULAo= --0016e64f4a68c9b04f0467a0fcf0--
