The kernel desk carried the day: a 7.3.0-3 release drops the forcing revert in 7.3/amd-iommu while a separate patch restores nvidia runtime D3 on 7.3, plus a chromium startup fix and CI that catches broken patches before review.
CachyOS Linux 7.3.0-3 CachyOS/linux
The release reverts "iommu/amd: Force identity mode for selected GPUs only" in the 7.3/amd-iommu branch, so identity mode is no longer forced on the listed GPUs in this build. It also carries the 7.3/t2 Apple SMC backend and watchdog driver commits.
7.3/misc: nvidia: fix runtime D3 CachyOS/kernel-patches
On 7.3 the 615 driver never enables runtime D3, because kthreads now start in nullfs and the nv-probe kthread's filp_open() on the PCI config sysfs path fails, leaving the dGPU in D0; 610 works on 7.3 and 615 works on 7.2. The patch is the fix that landed here.
Match upstream (aur) CachyOS/cachyos-aur-derived
The derived package now matches upstream AUR, which the author says "will fix chromium not starting." The change is carried into the repo by the ungoogled-chromium commit, which also bumps pkgrel.
Add makepkg check pipeline (#2038) CachyOS/CachyOS-PKGBUILDS
The new pipeline does not build packages, but verifies that patches apply and checksums are correct, which the author says accelerates review of PRs. Follow-up commits clean up the pipeline's rough edges.
fix(profiles): exclude non-hybrid CPUs from intel-lpmd CachyOS/chwd
intel-lpmd only supports hybrid Intel CPUs, but the cpu_family/cpu_models filter also matched non-hybrid Alder Lake SKUs, so the daemon was installed and exited immediately there; the profile now sets cpu_hybrid to skip them. That key is new in chwd core and keys off whether the Atom PMU's cpus file lists a CPU, rather than a device blacklist. Elsewhere: plasmazones moved 3.5.1 to 3.5.2, the we...
