From: Yanko Kaneti <yaneti(a)declera.com> configs/fedora: Enable CONFIG_PCI_REALLOC_ENABLE_AUTO This should help with automatically allocating resources for hotplug PCI devices (e.g. U.2 NVMe) when the BIOS/firmware hasn't made provisions for that.

[OS-BUILD PATCH] [redhat] New configs in samples/damon
by CKI ARK Bot (via Email Bridge) 11 Mar '25

11 Mar '25

From: Fedora Kernel Team <kernel-team(a)fedoraproject.org> [redhat] New configs in samples/damon Hi, As part of the ongoing rebase effort, the following configuration options need to be reviewed. As a reminder, the ARK configuration flow involves moving unreviewed configuration options from the pending directory to the ark directory. In the diff below, options are removed from the pending directory and added to the ark hierarchy. The final options that need to be ACKed are the files that are being added to the ark hierarchy. If the value for a file that is added should be changed, please reply with a better option.
