We only reserve 3K now, and testing this in the existing UEFI test kit would be entirely achievable. Including the ability to remove this check from the kernel is just an invitation for someone to build a kernel without it and then be surprised when their machine fucks up. > We absolutely want to be able to draw a line under it and declare that > any firmware built after $SOMEDATE is expected to be fixed, so we don't > have to do these stupid workarounds, and we can make full use of the > available space. We have no way to guarantee that. Most board vendors don't turn up to the plugfests and aren't going to run anything we ship. -- Matthew Garrett | mjg59@srcf.ucam.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
