So when compiling for Cobalt, we work around the hardware bug, while for other platforms, we just disable MWI? Wouldn't it be possible to always (I mean, when a rev 65 chip is detected) work around the bug?Of course it is possible but it is not the same semantic as the initial patch (not that I know if it is right or not). So: - does the issue exist beyond Cobalt hosts ? - is the fix Cobalt-only ?
I don't think anyone has replied to this message yet. My understanding is that it's not Cobalt only but a problem in a specific revision of the chip, which the Cobalt happens to use. However, I'd be glad if somone else could comment. Peter, you read the errata right? -- Martin Michlmayr http://www.cyrius.com/
