NAME
usb_hcd_pci_probe - initialize PCI-based HCDs SYNOPSIS
int usb_hcd_pci_probe(struct pci_dev * dev, const struct pci_device_id * id); ARGUMENTS
dev USB Host Controller being probed id pci hotplug id connecting controller to HCD framework CONTEXT
!in_interrupt DESCRIPTION
Allocates basic PCI resources for this USB host controller, and then invokes the start method for the HCD associated with it through the hotplug entry's driver_data. Store this function in the HCD's struct pci_driver as probe. RETURN
0 if successful. COPYRIGHT

NAME
arcmsr -- Areca Technology Corporation SATA/SAS RAID controller SYNOPSIS
arcmsr* at pci? dev ? function ? DESCRIPTION
The arcmsr driver provides support for the PCI-X and PCI Express RAID controllers from Areca Technology Corporation: - ARC-1110 PCI-X 4 Port SATA RAID Controller - ARC-1110ML PCI-X 4 Port SATA RAID Controller - ARC-1120 PCI-X 8 Port SATA RAID Controller - ARC-1120ML PCI-X 8 Port SATA RAID Controller - ARC-1130 PCI-X 12 Port SATA RAID Controller - ARC-1130ML PCI-X 12 Port SATA RAID Controller - ARC-1160 PCI-X 16 Port SATA RAID Controller - ARC-1160ML PCI-X 16 Port SATA RAID Controller - ARC-1170 PCI-X 24 Port SATA RAID Controller - ARC-1200 Rev A PCI Express 2 Port SATA RAID Controller - ARC-1202 PCI Express 2 Port SATA RAID Controller - ARC-1210 PCI Express 4 Port SATA RAID Controller - ARC-1220 PCI Express 8 Port SATA RAID Controller - ARC-1230 PCI Express 12 Port SATA RAID Controller - ARC-1230ML PCI Express 12 Port SATA RAID Controller - ARC-1231ML PCI Express 12 Port SATA RAID Controller - ARC-1260 PCI Express 16 Port SATA RAID Controller - ARC-1260ML PCI Express 16 Port SATA RAID Controller - ARC-1261ML PCI Express 16 Port SATA RAID Controller - ARC-1280 PCI Express 24 Port SATA RAID Controller - ARC-1280ML PCI Express 24 Port SATA RAID Controller - ARC-1680 PCI Express 8 Port SAS RAID Controller - ARC-1680LP PCI Express 8 Port SAS RAID Controller - ARC-1680i PCI Express 8 Port SAS RAID Controller - ARC-1680x PCI Express 8 Port SAS RAID Controller - ARC-1681 PCI-X 8 Port SAS RAID Controller These controllers support RAID levels 0, 1, 1E, 3, 5, 6, and JBOD using either SAS or SATA II drives. arcmsr supports management and monitoring of the controller through the bioctl(8) and envstat(8) commands. Please note, however, that to use some features that require special privileges, such as creating/removing hot-spares, pass-through disks or RAID volumes will require to have the password disabled in the firmware; otherwise a Permission denied error will be reported by bioctl(8). When a RAID 1 or 1+0 volume is created, either through the bioctl(8) command or controller's firmware, the volume won't be accessible until the initialization is done. A way to get access to the sd(4) device that corresponds to that volume without rebooting, is to issue the fol- lowing command (once the initialization is finished): $ scsictl scsibus0 scan any any The arcmsr driver will also report to the kernel log buffer any error that might appear when handling firmware commands, such as used by the bioctl(8) command. EVENTS
The arcmsr driver is able to send events to powerd(8) if a volume or any drive connected to the volume is not online. The state-changed event will be sent to the /etc/powerd/scripts/sensor_drive script when such condition happens. SEE ALSO
