I've created a patch that adresses this issue (TSC timing) so that it works on Pentium Ms. I've submitted it to the maintainer and he will release a new version. But according to him this will take some time, so I'm submitting it here, too. I've tested the resulting binaries on all x86 hardware I have (PIII, PIV, PM, AthXP) and found no problems. As the original assembly code didn't work elsewhere (SDLcam has an alternative codepath without assembly), I've not bothered testing it anywhere else. klausman@gentoo.org 2005-10-13 09:19:46 0000 Created an attachment (id=70575) TSC assembly fix for SDLcam 0.7.3 vapier@gentoo.org 2005-10-13 17:36:06 0000 thanks, now in portage 70575 2005-10-13 09:19 0000 TSC assembly fix for SDLcam 0.7.3 sdlcam-tsc-fix.patch text/plain LS0tIG1pc2MuYy5vcmlnCTIwMDUtMTAtMDggMTE6NDQ6MzIuMDAwMDAwMDAwICswMjAwCisrKyBt aXNjLmMJMjAwNS0xMC0wOCAxMTo0NjoxMy4wMDAwMDAwMDAgKzAyMDAKQEAgLTI1LDYgKzI1LDEx IEBACiAjaW5jbHVkZSAiZHluX21pc2MuaCIKICNpbmNsdWRlICJtaXNjLmgiCiAKKyNkZWZpbmUg cmR0c2MobG93LGhpZ2gpIFwKKyAgICAgX19hc21fXyBfX3ZvbGF0aWxlX18oInJkdHNjIiA6ICI9 YSIgKGxvdyksICI9ZCIgKGhpZ2gpKQorCisKKwogY2hhciAqeFN0cmR1cCAoY29uc3QgY2hhciAq dCkge3t7CiAgIGNoYXIgKnJldDsKICAgcmV0ID0gc3RyZHVwICh0KTsKQEAgLTQyLDE4ICs0Nyw5 IEBACiAKIHZvaWQgZ2V0VGltZVN0YW1wQ291bnRlciAoIFRpbWVTdGFtcENvdW50ZXIgKnQgKSB7 e3sKICNpZmRlZiBUSU1FUgkKLQl1bnNpZ25lZCBpbnQgaD10LT5oaWdoOwotCXVuc2lnbmVkIGlu dCBsPXQtPmxvdyA7Ci0JYXNtICgJCi0JCSJwdXNoICUlZWF4CVxuIgotCQkicHVzaCAlJWVkeAlc biIKLQkJInJkdHNjCQlcbiIKLQkJIm1vdmwgJSVlYXgsJTEJXG4iCi0JCSJtb3ZsICUlZWR4LCUw CVxuIgotCQkicG9wICAlJWVkeAlcbiIKLQkJInBvcCAgJSVlZHgJXG4iCi0JCTogIj1tIiAoaCkg LCAiPW0iIChsKQotCSAgICApOworCXVuc2lnbmVkIGxvbmcgaD10LT5oaWdoOworCXVuc2lnbmVk IGxvbmcgbD10LT5sb3cgOworCXJkdHNjKGwsaCk7CiAJdC0+aGlnaCA9IGg7CiAJdC0+bG93ICA9 IGw7CiAjZWxzZQkKLS0tIG1pc2MuaC5vcmlnCTIwMDUtMTAtMDggMTM6NTI6MDUuMDAwMDAwMDAw ICswMjAwCisrKyBtaXNjLmgJMjAwNS0xMC0wOCAxMzo1MjoxOC4wMDAwMDAwMDAgKzAyMDAKQEAg LTI0LDcgKzI0LDcgQEAKIAogY2hhciAqeFN0cmR1cCAoY29uc3QgY2hhciAqdCk7CiAKLXR5cGVk ZWYgc3RydWN0IHsgdW5zaWduZWQgaW50IGhpZ2gsIGxvdzsgfSBUaW1lU3RhbXBDb3VudGVyOwor dHlwZWRlZiBzdHJ1Y3QgeyB1bnNpZ25lZCBsb25nIGhpZ2gsIGxvdzsgfSBUaW1lU3RhbXBDb3Vu dGVyOwogdm9pZCBnZXRUaW1lU3RhbXBDb3VudGVyICggVGltZVN0YW1wQ291bnRlciAqdCApOwog dm9pZCBTdGFydF9UaW1lciAodW5zaWduZWQgaW50IGlkeCk7CiB2b2lkIEVuZGVfVGltZXIgICh1 bnNpZ25lZCBpbnQgaWR4KTsK
