Meeting request to move meeting to Tuesday, 1 hour later. New time works better for current attendees. Haseeb, Marvell: Hi Cathal, other days at this time would work for me. I have a weekly team meeting at this time. If possible please reschedule. Cathal, Intel: I’ll collect consensus to move call to encourage maximum number of attendee’s. 2. Thomas, Mellanox: Windows not currently in DPDK UNH community lab, but they do have plans to increase scope of the lab testing. Current Community lab is focused on unit testing. NXP/Mellanox/Intel HW is currently available in the lab. We need unit tests for windows. Tal (Mellanox) logged bug, requesting the addition of windows testing https://bugs.dpdk.org/show_bug.cgi?id=286. Community lab next meeting is 04-jun-19. 3. Harini, Microsoft: I’ve posted a blog on DPDK v19.05 release with Windows and inviting more participation in the community. https://techcommunity.microsoft.com/t5/Networking-Blog/DPDK-releases-v19-05-introduces-Windows-Support/ba-p/633927 Please amplify in your circles, if you can. 4. Thomas, Mellanox: Should we have a page with an up-to-date status of the work? Would be good to have an overview of the progress, even if it's as simple as a progress bar. Thomas guidance: public editable page + public info page for call out info on Windows Development progress. 5. Ranjit, Intel: Below is a list of directories, files or functions which we need to check to make basic DPDK work on Windows. If something is missing, please update. The goal of this list is to collect status on what is complete, and plan what should be done next. It will help to share the workload among all volunteers during the next few months. buildtools/pmdinfogen - not ported to Windows usertools/dpdk-devbind.py - not ported to Windows drivers/bus/vdev - not ported to Windows drivers/bus/pci - ported to Windows in 18.08** repo (using clang-cl) lib/librte_pci - ported to Windows in 18.08** repo (using clang-cl) lib/librte_cmdline - ported to Windows in 18.08** repo (using clang-cl) lib/librte_kvargs - ported to Windows in 18.08** repo (using clang-cl) lib/librte_ring - ported to Windows in 18.08** repo (using clang-cl) lib/librte_mempool - ported to Windows in 18.08** repo (using clang-cl) lib/librte_mbuf - ported to Windows in 18.08** repo (using clang-cl) lib/librte_net - ported to Windows in 18.08** repo (using clang-cl) lib/librte_eal/common/include/eal_log.c (Pallavi working on this file) lib/librte_eal/common/include/rte_errno.h lib/librte_eal/common/include/rte_string_fns.h lib/librte_eal/common/include/rte_lcore.h lib/librte_eal/common/arch/x86/rte_cpuflags.c (Tal working on this file) lib/librte_eal/common/arch/x86/rte_cycles.c (Tal working on this file) lib/librte_eal/common/eal_common_options.c (Pallavi working on this) (Some header file issues working to create windows port.

Haseeb, Marvell: in the process of supporting Marvell FastlinQ cards on the 18.08 draft branch. The changes are done in netuio, pci and qede modules. We’re completing internal review and will be able to send the changes for review soon. 7. Ranjit/Pallavi, Intel: We may need to abstract out some common code, if it’s not supported on windows. One possible solution is to get someone to see if we need to create a posix common code and one for windows common code. Need to understand the blockers Pallavi has hit. (This could become a road block later - need to confirm the licensing are correct for usage) Is lib_bsd a possible source of header files with correct licensing? This is required for full EAL functionality. The community will give guidance on acceptability of proposed changes/next steps Please check this list (3rd party headers in windows draft repo: windpdk-v18.08-clang) and mention what is done or in progress. The best would be to reference some patches or commits to help progress together as a community. dirent.h getopt.h pthread.h -> contains implementation rand48.h sched.h -> contains implementation syslog.h termios.h unistd.h -> contains implementation net/ethernet.h netinet/in.h -> contains implementation netinet/tcp.h -> contains only include guard sys/netbsd/queue.h -> contains implementation sys/_iovec sys/_sockaddr sys/_storage.h sys/_termios.h sys/_types.h sys/cdefs.h -> contains only include guard sys/mman.h sys/queue.h 8. Ranjit, Intel: Meson/make - Output from ninja will get passed to CI reporting to display on patch status. Intel working on this. Hope to have it working soon. 9. Harini, Microsoft: MS Patches in preparation of Windows support for CXGBE is already available in 19.05 repo upstream. CXGBE PMD will compile fine against Windows DPDK using Intel C++ Compiler up to v19.02. [PATCH 0/4] net/cxgbe: fix build for Microsoft Windows OS support (Rahul Lakkireddy) [PATCH 1/4] net/cxgbe: use relative paths for including header files (Rahul Lakkireddy) [PATCH 2/4] net/cxgbe: fix macros related to logs for Windows (Rahul Lakkireddy) [PATCH 3/4] net/cxgbe: only redefine symbols when not available for Windows (Rahul Lakkireddy) 9. Ravi, Cisco: Ravi Anand team working with the PMD for the Cisco Virtual interface Cards. 10. Tal, Mellanox: For bus/pci : Can refer to windpdk-v18.08 branch in draft repo. Code there is built using clang and functional. (No meson support yet). Currently working on Ninja & meson compiler. Active, but hit some issues. Resolved by upgrading (able to debug: upgrade CLang to version 8.0.0) & recompiling. Now able to build in debug mode (DPDK.org guidance needs to be updated). For new patches from 19.08 onwards: use repo windpdk-next-dev (Harini is the maintainer). Windows will only use meson, going forward. Currently compiling with clang, but not with meson.
