4.7. TX Non-Posted Metering Requirement on Application
PCI Express* HIP implements a finite number of RX Completion Buffers for its header and data. However, in endpoint mode, it advertises infinite credit to the host. Hence,, the application logic needs to implement metering logic on its TX Non-Posted requests such that it does not issue more requests than allowed to avoid overflowing the completion buffer.
Completion Buffer | Depth | Width (in bits) |
---|---|---|
Port 0 Completion Header | 286 | 128 |
Port 0 Completion Data | 1730 | 64 |
RX Buffer Segment | x4 Controller | |
---|---|---|
Scaled Flow Control Disabled (Credit) | Scaled Flow Control Enabled (Scale Factor, Credit) | |
