Public bug reported: We understand that the z patches for spectre mitigation in the kernel include introduction of an interface to enable or disable branch prediction on a per-process basis.
I don't know what that interface looks like and what the usability is for production systems. It would be helpful to have some analysis here. Is it done in a way that can be set before the process starts executing? Is it inherited? Is it bound to the filesystem in some way? cgroups? ** Affects: linux (Ubuntu) Importance: Undecided Status: Triaged ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Changed in: linux (Ubuntu) Status: Incomplete => Triaged -- 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/1751851 Title: request for analysis of per-process flag for controlling branch prediction on z Status in linux package in Ubuntu: Triaged Bug description: We understand that the z patches for spectre mitigation in the kernel include introduction of an interface to enable or disable branch prediction on a per-process basis.
