Hi all, Is the current ACPI linux subsystem, that you find in the official Linus tree, compliant (even partially) with ACPI 6 ? (which was released in April 2015) or is it now compliant only with ACPI 5 ?
ACPI 6 have lots of new features, such as add support for NVDIMM (persistent memory), hierarchical lower-power idle states of CPUs, CPU clusters, and some support for ARM platforms (GIC, SMMU and etc.), and more... so what the specific features are you referring to?
What are the plans for ACPI 6? Is there already some git branch for it ?
For all the ACPI 6 new features, ACPICA already add its support in 4.2, and some of the ACPI driver support also is ready, such as support for persistent memory [1] is ready, and Linaro is leading the ACPI 6.0 for ARM support, but as far as I can know, some of ACPI 6.0 features are still under development at now. I think the main support for ACPI 6.0 is in Rafael's tree: git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git [1]: https://lwn.net/Articles/640891/ Thanks Hanjun -- 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
