Queue sharing and reconfiguration in PCI express links

1. A method for queue sharing in a point to point link comprising:

determining, in an electrical device, whether a virtual channel/sub-link is inactive; and

in response to a determination that at least one virtual channel/sub-link is inactive, reallocating queue space from the at least one inactive channel to at least one active channel;

writing, in an electrical device, offset information of a virtual channels' queue region in a virtual channel/sub-link posted/none-posted/completion data base address register for data to be transmitted across a known number of virtual channels; and

transmitting data, in an electrical device, across the known number of virtual channels.

2. The method of claim 1 , wherein the data is transmitted through a PCI express link.

3. An electronic device comprising:

at least one processor;

at least one PCI express link;

a virtual channel/sub-link flow-control module;

a memory module communicatively connected to the one or more processors and including logic instructions which, when executed on the one or more processors cause the one or more processors to:

determine, in an electrical device, whether a virtual channel/virtual channel/sub-link is inactive, and

in response to a determination that at least one virtual channel/sub-link is inactive, reallocate queue space from the at least one inactive channel to at least one virtual channel;

logic to write offset information of a virtual channels' queue region in a virtual channel/sub-link posted/none-posted/completion data base address register for data to be transmitted across a known number of virtual channels; and

logic to transmit data, in an electrical device, across the known number of virtual channels.
