That is a good example of what should be verified, though I don't know of an automatic way to test it. Note that Intel already tells the BIOS vendors this when we tell them what we think they should do, and we do this in our example designs. (though 18 months ago that was not the case). On systems where the vendor cares about Linux enough to try to get a Centrino Mobile Technology brand, there is a simple compliance test (not fancy like WHQL) and they will fail if they don't re-initialize video on resume from S3. Of course the population of vendors who ship Linux on their laptops is small, and the subset of them that go for a CMT logo is even smaller. But those are the ones for us to focus on, it is futile to try to get a Windows-only vendor to lift a finger to support Linux. >And, what's probably a harder question, >is there any real chance of there being sufficient political will in >Intel to make passing this a requirement for claiming ACPI compliance? My view is that it is impossible for anybody to claim ACPI compliance because there is no ACPI compliance test to certify it. I doubt that a test based on Linux would fly in the committee that defines the ACPI spec -- particularly since the Linux distributors have not even bothered to join the commmitte and get a vote at the table. However, what we really do care about here are the vendors that _do_ care about Linux. They would be interested in running a Linux based test if they were available. -Len - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
