Hi Jim, ACPI support for the Marvell Armada 7k/8k NIC finally landed in the mainline kernel. I backported all required stuff from the upstream to v4.11 and I'm about to create patch that adds a support in the kernel. Please check if my understanding of adding the patch is sufficient: 1. Place squashed patch in SOURCES/ 2. Update SPECS/kernel-alt.spec with the added patch ("5a27f64 - adds thunderx support patch per cavium list request" is a good reference for that) 3. Update: SOURCES/kernel-alt-4.11.0-aarch64-debug.config SOURCES/kernel-alt-4.11.0-aarch64.config And here's where I have problems. I took kernel-alt-4.11.0-aarch64.config to my v4.11 branch and tried to first build kernel directly from that point - it cannot be done flawlessly, as one have to manually choose multiple kernel CONFIGs resolution. Further I wanted to use make menuconfig enabled CONFIG_ARCH_MVEBU=y and CONFIG_MVPP2=m. It would be great, if you were able to let know, what's the easiest and quickest way to apply and test new patches on top of sig-altarch7-aarch64 branch. Thanks, Marcin
