Windows Prerequisites
---------------------
-- Follow the DPDK `Getting Started Guide for Windows <https://doc.dpdk.org/guides/windows_gsg/index.html>`_ to setup the basic DPDK environment.
+- Follow the :doc:`guide for Windows <../windows_gsg/run_apps>`
+ to setup the basic DPDK environment.
- Identify the IntelĀ® Ethernet adapter and get the latest NVM/FW version.

Pre-Installation Configuration
------------------------------
These ICE_DBG_XXX are defined in ``drivers/net/ice/base/ice_type.h``.
+- ``1PPS out support``
+
+ The E810 supports four single-ended GPIO signals (SDP[20:23]). The 1PPS
+ signal outputs via SDP[20:23]. User can select GPIO pin index flexibly.
+ Pin index 0 means SDP20, 1 means SDP21 and so on. For example::
+
+ -a af:00.0,pps_out='[pin:0]'
+
+- ``Low Rx latency`` (default ``0``)
+
+ vRAN workloads require low latency DPDK interface for the front haul
+ interface connection to Radio. By specifying ``1`` for parameter
+ ``rx_low_latency``, each completed Rx descriptor can be written immediately
+ to host memory and the Rx interrupt latency can be reduced to 2us::
+
+ -a 0000:88:00.0,rx_low_latency=1
+
+ As a trade-off, this configuration may cause the packet processing performance
+ degradation due to the PCI bandwidth limitation.
