R . Silva" Cc: "=?UTF-8?q?Ilpo=20J=C3=A4rvinen?=" , linux-pci@vger.kernel.org, linux-kernel@vger.kernel.org, linux-doc@vger.kernel.org, linux-kselftest@vger.kernel.org, linux-hardening@vger.kernel.org Content-Type: text/plain; charset="utf-8" Hi Bjorn, Ilpo, Gentle ping on this series - it has been two weeks since v3 was posted and I haven't seen any feedback yet. v3 restructured the original monolithic LMR driver (v7) into the 3-patch stack Ilpo suggested during the v7 review, moving the link endpoint traversal into the PCI core rather than duplicating it in the feature driver: 1/3 PCI: Add pcie_get_link_endpoints() helper 2/3 PCI/ASPM: Add pci_aspm_inhibit() helper for temporary link state suppression 3/3 PCI/pcie: Add PCIe Lane Margining at Receiver (LMR) support The LMR driver itself is now strictly self-contained in drivers/pci/pcie/margin.c, with no modifications to drivers/pci/pci.c, drivers/pci/pci-driver.c or drivers/pci/pci.h. The series builds clean with W=1 and is checkpatch clean on x86_64 and arm64. Feedback on patches 1 and 2 would be especially useful, since they are the core helpers patch 3 builds on. I'm happy to respin if the split isn't what you had in mind, or to rebase onto a newer base if that helps review. Thanks, Priyank
