[OS-BUILD PATCHv3] [redhat] New configs in drivers/hwtracing
by CKI ARK Bot (via Email Bridge) 16 Apr '25

16 Apr '25

From: Fedora Kernel Team <kernel-team(a)fedoraproject.org> [redhat] New configs in drivers/hwtracing 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.

[OS-BUILD PATCHv3 0/2] redhat: enable Rust code in ELN
by Scott Weaver (via Email Bridge) 16 Apr '25

16 Apr '25

From: Scott Weaver on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/3822 This enables Rust code in the ELN kernel, which requires enabling CONFIG_EXTENDED_MODVERSIONS and CONFIG_GENDWARFKSYMS. The DRM panic with QR code functionality is the first Rust based code to be enabled. A QR code URL is not defined but we will likely want to update that before enabling this in RHEL.
