Previously some PCI speed strings came from pci_speed_string(), some came from the PCIe-specific PCIE_SPEED2STR(), and some came from a PCIe-specific switch statement. These methods were inconsistent: pci_speed_string() PCIE_SPEED2STR() switch ------------------ ---------------- ------ 33 MHz PCI ... 2.5 GT/s PCIe 2.5 GT/s 2.5 GT/s 5.0 GT/s PCIe 5 GT/s 5 GT/s 8.0 GT/s PCIe 8 GT/s 8 GT/s 16.0 GT/s PCIe 16 GT/s 16 GT/s 32.0 GT/s PCIe 32 GT/s 32 GT/s Standardize on pci_speed_string() as the single source of these strings. Note that this adds ".0" and "PCIe" to some messages, including sysfs "max_link_speed" files, a brcmstb "link up" message, and the link status dmesg logging, e.g., nvme 0000:01:00.0: 16.000 Gb/s available PCIe bandwidth, limited by 5.0 GT/s PCIe x4 link at 0000:00:01.1 (capable of 31.504 Gb/s with 8.0 GT/s PCIe x4 link) I think it's better to standardize on a single version of the speed text. Previously we had strings like this: /sys/bus/pci/slots/0/cur_bus_speed: 8.0 GT/s PCIe /sys/bus/pci/slots/0/max_bus_speed: 8.0 GT/s PCIe /sys/devices/pci0000:00/0000:00:1c.0/current_link_speed: 8 GT/s /sys/devices/pci0000:00/0000:00:1c.0/max_link_speed: 8 GT/s This changes the latter two to match the slots files: /sys/devices/pci0000:00/0000:00:1c.0/current_link_speed: 8.0 GT/s PCIe /sys/devices/pci0000:00/0000:00:1c.0/max_link_speed: 8.0 GT/s PCIe Based-on-patch by: Yicong Yang <yangyicong@hisilicon.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
