Abstract:
A packet is identified at a port of a serial data link, and it is determined that the packet is associated with an error. Entry into an error recovery mode is initiated based on the determination that the packet is associated with the error. Entry into the error recovery mode can cause the serial data link to be forced down. In one aspect, forcing the data link down causes all subsequent inbound packets to be dropped and all pending outbound requests and completions to be aborted during the error recovery mode.

Claim (Index 51):
A system comprising:\n a first device; and a second device connected to the first device by a serial data link, wherein the second device comprises:\n a capability structure associated with a downstream port error containment mode; and \n a downstream port, wherein the downstream port comprises hardware-implemented logic comprising:\n input/output (I/O) logic to support communication on the serial data link with the first device; \n error logic to:\n determine an uncorrectable error associated with a packet; \n determine that a particular bit is set within the capability structure to indicate that the downstream port error containment mode is enabled for the downstream port, wherein the port error containment mode is to contain uncorrectable errors at the downstream port; \n set a downstream port error containment status bit to trigger the downstream port error containment mode based at least in part on the particular bit set to indicate that the downstream port error containment mode is enabled; \n halt traffic downstream from the downstream port in the downstream port error containment mode to avoid spread of data corruption associated with the error and to permit error recovery, wherein training sequences are to be sent on the link by the downstream port to force the link into a disabled link state and halt the traffic, and the traffic is to be halted without a reset of the downstream port; and \n detect that the downstream port error containment status bit is cleared by software, \n \n \n wherein the I/O logic is to attempt to retrain the link based on clearing of the downstream port error containment status bit.
