Hello, I just noticed in the new x86-S rfc that Intel published that there will be no further support for io port access for processes in ring 3. Thankfully, this doesn't look like it will impact seL4, which provides capabilities to special objects representing port ranges on x86, which are then implemented in the kernel. Just in case anyone was wondering if there will be any impact, since this is the one thing that stuck out to me.
Here's Intel's RFC: https://www.intel.com/content/www/us/en/developer/articles/technical/envisioning-future-simplified-architecture.html I think I might steal your IO port API for newer versions of Coyotos, which /is/ impacted by the change. TBF, I think seL4 has a better IRQ handling interface than the one we currently have too. I guess it's only fair it goes both ways! -- William ML Leslie _______________________________________________ Devel mailing list -- [email protected] To unsubscribe send an email to [email protected]
