What is PCIe hot reset?

A ‘hot reset’ is a conventional reset that is triggered across a PCI express link. A hot reset is triggered either when a link is forced into electrical idle or by sending TS1 and TS2 ordered sets with the hot reset bit set.

How do you reset a PCI Express slot?

Remove the device and rescan the PCIe bus Removing the PCIe device via the remove function in its directory and reloading it via the PCIe bus’ rescan function causes the kernel to power-cycle the PCIe device without rebooting your computer.

What is fundamental reset?

Fundamental Reset causes a device’s state machines, hardware logic, port states and configuration registers (except sticky registers of a device that can draw valid Vaux) to initialize to their default conditions. There are two types of Fundamental Reset: Cold Reset.

What is function level reset?

The PCIe FLR (Function Level Reset) mechanism enables software to quiesce and reset Endpoint hardware with Function-level granularity. These functions can expose FLR capability and existing PCIe compatible software can issue FLR to these functions.

What is MMIO high granularity size?

The big change here was the MMIOHBase and MMIO High Size changes to 512G and 256G respectively from 256GB and 128GB.

What is peripheral mapped I O?

PERIPHERAL MAPPED I/O INTERFACING IN instruction is used to access input device and OUT instruction is used to access output device. Each I/O device is identified by a unique 8-bit address assigned to it.

What is a hot reset?

Is PCI Express and PCIe the same?

What Is PCI Express? PCI Express, also abbreviated as PCIe, refers to the peripheral component interconnect express. As the successor of PCI, PCI Express is also a type of connection standard carried out by Intel in 2001, which provides more bandwidth and is more compatible with existing operating systems than PCI.
