e434e54d - PCI: hotplug: Add OCTEON PCI hotplug controller driver

Mon, 11 Nov 2024 13:45:11 +0000

PCI: hotplug: Add OCTEON PCI hotplug controller driverAdd a PCI hotplug controller driver for the OCTEON PCIe device. The OCTEONPCIe device is a multi-function device where function 0 serves as the PCIhotplug controller.There is an out-of-band management console interface to firmware running onfunction 0 whereby an administrator can disable functions to save power orenable them with one of several personalities (virtio-net, virtio-crypto,NVMe, etc) for the other functions. Function 0 initiates hotplug eventshandled by this driver when the other functions are enabled or disabled. +--------------------------------+ | Root Port | +--------------------------------+ | PCIe | +---------------------------------------------------------------+ | OCTEON PCIe Multifunction Device | +---------------------------------------------------------------+ | | | | | | | | +---------------------+ +----------------+ +-----+ +----------------+ | Function 0 | | Function 1 | | ... | | Function 7 | | (Hotplug controller)| | (Hotplug slot) | | | | (Hotplug slot) | +---------------------+ +----------------+ +-----+ +----------------+ | | +-------------------------+ | Controller Firmware | +-------------------------+The hotplug controller driver enables hotplugging of non-controllerfunctions within the same device. During probing, the driver removesthe non-controller functions and registers them as PCI hotplug slots.These slots are added back by the driver, only upon request from thedevice firmware.The controller uses MSI-X interrupts to notify the host of hotplugevents initiated by the OCTEON firmware. Additionally, the driverallows users to enable or disable individual functions via sysfs slotentries, as provided by the PCI hotplug framework.Link: https://lore.kernel.org/r/20241111134523.2796699-1-sthotton@marvell.comCo-developed-by: Vamsi Attunuru Signed-off-by: Vamsi Attunuru Signed-off-by: Shijith Thotton [bhelgaas: use pci_info() when possible]Signed-off-by: Bjorn Helgaas List of files: /linux-6.15/drivers/pci/hotplug/Kconfig

66725152 - PCI/hotplug: PowerPC PowerNV PCI hotplug driver

Fri, 20 May 2016 06:41:42 +0000

PCI/hotplug: PowerPC PowerNV PCI hotplug driverThis adds standalone driver to support PCI hotplug for PowerPC PowerNVplatform that runs on top of skiboot firmware. The firmware identifieshotpluggable slots and marked their device tree node with proper"ibm,slot-pluggable" and "ibm,reset-by-firmware". The driver scansdevice tree nodes to create/register PCI hotplug slot accordingly.The PCI slots are organized in fashion of tree, which means onePCI slot might have parent PCI slot and parent PCI slot possiblycontains multiple child PCI slots. At the plugging time, the parentPCI slot is populated before its children. The child PCI slots areremoved before their parent PCI slot can be removed from the system.If the skiboot firmware doesn't support slot status retrieval, the PCIslot device node shouldn't have property "ibm,reset-by-firmware". Inthat case, none of valid PCI slots will be detected from device tree.The skiboot firmware doesn't export the capability to access attentionLEDs yet and it's something for TBD.Signed-off-by: Gavin Shan Acked-by: Bjorn Helgaas Signed-off-by: Michael Ellerman List of files: /linux-6.15/drivers/pci/hotplug/Kconfig

PCI Hotplug: cpqphp: don't use pci_find_slot()Convert uses of pci_find_slot to modern API.In the conversion sites, we end up calling pci_dev_put() right away.This may seem like it misses the entire point of doing something likepci_get_bus_and_slot(), since we drop the reference so soon, but it turnsout we don't actually do much with the returned pci_dev.I plan on untangling cpqphp further, but clearly cpqphp never worried toomuch about a properly refcounted pci_dev anyway. For now, this conversionseems reasonable, as it gets rid of the last in-tree caller of pci_find_slot.Signed-off-by: Alex Chiang Signed-off-by: Jesse Barnes List of files: /linux-6.15/drivers/pci/hotplug/Kconfig
