Pcie enhanced allocation
SpletIt is proposed that the tracking of this info and allocation status (free or unallocated) of PCIe devices should happen in the Resource Tracker on the compute node. Step 1e: … SpletThe MSI capability was first specified in PCI 2.2 and was later enhanced in PCI 3.0 to allow each interrupt to be masked individually. The MSI-X capability was also introduced with PCI 3.0. ... Upon a successful allocation, the caller should use pci_irq_vector() to get the Linux IRQ number to be passed to request_threaded_irq().

Each function's 4KB configuration space starts at a 4KB-aligned address within the 256MB memory space set aside as configuration space: Address bits 63:28 indicates the 256MB-aligned base address of the overall Enhanced Configuration address range. Address bits 27:20 select the target bus (1-of-256).

SpletWhen a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus. Nothing more to add to that. "PCIe bus enumeration" topic will answer your 2nd question. Your third question is vague. You mean slave PCIe device. SpletIt seems it has an enhanced motherboard layout taken from the 1821+. It seems, although that could not be totally accurate, that the first 4 drives shares a PCIe 3.0 x1 lane and the last 4 drives shares another PCIe 3.0 x1 lane so that's a total of 2*985 MB/s = 1970 MB/s, achievable if you put 8 HDDs of ~250 MB/s write speed in RAID 0.
SpletUnderstanding I/O Resource Management (IORM) IORM manages the storage server I/O resources on a per-cell basis. Whenever the I/O requests start to saturate a cell's … The Device ID (DID) and Vendor ID (VID) registers identify the device (such as an IC), and are commonly called the PCI ID. The 16-bit vendor ID is allocated by the PCI-SIG. The 16-bit device ID is then assigned by the vendor. There is an inactive project to collect all known Vendor and Device IDs. (See the external links below.)
SpletUnderstanding I/O Resource Management (IORM) IORM manages the storage server I/O resources on a per-cell basis. Whenever the I/O requests start to saturate a cell's capacity, IORM schedules incoming I/O requests according to the configured resource plans.
