- This series breaks external compilation, as the external Makefile was not updated. /usr/bin/ld: /tmp/cce4w26j.o: in function `new_device': main.c:(.text+0x173): undefined reference to `ioat_transfer_data_cb' /usr/bin/ld: main.c:(.text+0x178): undefined reference to `ioat_check_completed_copies_cb' /usr/bin/ld: /tmp/cce4w26j.o: in function `main': main.c:(.text.startup+0x25e): undefined reference to `open_ioat' collect2: error: ld returned 1 exit status - This series imposes a dependency on the raw/ioat driver for no reason. $ meson configure build -Ddisable_drivers=raw/ioat $ ninja-build -C build -j4 ... examples/meson.build:91:4: ERROR: Problem encountered: Missing dependency "raw_ioat" for example "vhost" The check for the architecture == x86 is wrong. The example must check for RTE_RAW_IOAT presence. Please provide fixes before rc4 or I will revert this series. Thanks. -- David Marchand
