+#### Bringing support for Microsoft Visual Studio on Windows
+
+Starting with release 23.07 integration will begin to formally support
+the Microsoft Visual Studio toolset. Patches will be introduced that
+incrementally phase in full support of the core DPDK libraries, the DPDK
+unit tests and drivers.
+
+The following is a draft plan of work targeting the 23.11 release. The
+plan is subject to change depending on delays and discussions from the
+review process. Contributions toward this plan from the community are
+welcome.
+
+1. meson.build Changes
+
+Meson does not fully abstract away command line arguments to toolchains
+so an initial series is available that unblocks the use of MSVC. This
+change is pre-requisite to undertake subsequent steps.
+
+http://patches.dpdk.org/project/dpdk/list/?series=26662
+
+2. MSVC CI Pipeline Prerequisite
+
+Enablement of the DPDK CI pipeline is fundamental to efficiently
+progressing porting work for the MSVC toolset. A minimal patch series
+will be supplied to build the kvargs and telemetry libraries only.
+
+3. MSVC CI Pipeline Bootstrap
+
+With (2) complete work will be done to onboard CI pipeline for the MSVC
+toolset. Initially the pipeline will only guarantee compilation but as
+additional libraries and tests are ported will also allow execution of
+the DPDK unit tests.
+
+4. MSVC EAL porting
+
+EAL is pre-requisite for porting all other libraries, drivers and unit
+tests. Porting of EAL will be broken down into multiple-patch series to
+address & decouple from the toolchain intrinsics topic.
+
+Because EAL depends on atomics the porting of EAL cannot be completed
+until the DPDK 23.11 release. In the interim abstractions introduced will
+only have the non-MSVC implementation tested during integration on the
+relevant platforms.
+
+5. Unit Test Library Porting
+
+In addition to EAL there are several libraries required for the basic
+DPDK unit test harness. Multiple series will be submitted to port the
+appropriate libraries to allow the harness to be invoked.
+
+6. Unit Test Enablement
+
+Fundamental unit tests (typically those testing EAL functionality) will
+be ported to MSVC. For tests that depend only on EAL this is not expected
+to require code change but is just re-enabling compilation of the tests
+allowing them to be built and run.
+
+7. MSVC CI Pipeline Test Enablement
+
+With initial DPDK unit tests building & passing the CI pipeline will be
+updated to run the unit tests.
+
+8. Driver Porting
+
+Candidate drivers will be selected from the set currently built with
+clang. Multiple series will be submitted (probably per-driver) with
+changes to port to MSVC.
+
+Nearing the 23.11 release timeframe the plan will be reviewed to
+understand and schedule porting work beyond the 23.11 release.
+
+#### Kernel Mode Drivers
+
+Concurrent work is in progress by Microsoft to provide functionality
+by the netuio driver for use by DPDK PMDs in the next release of
+Windows.
+
+Partners and providers of hardware & PMDs will be able to use the
+WHQL certification process to sign driver packages containing PMDs
+that utilize netuio functionality.

hi folks,

quick ping here. is there any comment on this? i'd like to see the
existing patches start to move in tree if this is satisfactory.

thanks!

Hi Tyler,

Would you like to update this roadmap patch for integration?

MSVC actually starts in 23.11.

yeah, at the time it was supposed to be 23.07 i've adjusted it to 23.11
in v2.

i've updated in v2 to talk about enable_stdatomic which is in discussion

i don't know, so i can't document it. surprisingly they don't tell us
what the 'next' will be named and version numbers are only determined
at release.

+EAL is pre-requisite for porting all other libraries, drivers and unit

+
+Beginning with the DPDK 23.11 release a new option enable_stdatomic will
+be introduced to allow DPDK toolchain platform combinations to be built
+with or without C11 stdatomic.h. The use of either the standard atomics
+or traditional builtin intrinsics will be placed behind a thin macro
+based abstraction in the rte_ namespace.
+
+5. Unit Test Library Porting
