None of these patches seems to be integrated int 4.4.0-124. So, we will need to backport them again. I will be working to get this done. What about artful (kernel 4.13). Are the patches still applying? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1744173 Title: rfi-flush: Switch to new linear fallback flush Status in The Ubuntu-power-systems project: In Progress Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Status in linux source package in Artful: In Progress Bug description: [Impact] Change flush from congruence-first with dependencies to linear with no dependencies, which increases flush performance by 8x on P8, and 3x on P9 (as measured with null syscall loop, which will have the flush area in the L2). The flush also becomes simpler and more adaptable to different cache geometries. [Test Case] TBD. [Regression Potential] The risk is deemed low since the changes are confined to POWER only and the provided test kernels have been tested by IBM.
