Some of these are bug\nfixes to enable compilation e.g. missing exports or meson.build files, while\nothers are suggested changes to enhance the API. All these patches are to be\napplied on top of [1] as they are mostly suggested changes to that RFC i.e.\npatches to the patch!\n\nThe final patch includes some basic sanity tests for copy operations that we\nhave ported over from the ioat self-tests to use the dmadev APIs. The basic\ndataplane part of those tests is probably ok for now, but the initialization of\nqueues in that test code may need some enhancement. Feedback welcome.\n\nA tree with all these patches applied can be got at [2] if anyone wants to use\nthat as a basis for working on drivers, or for other discussion.\n\n[1] http://patches.dpdk.org/project/dpdk/patch/1625231891-2963-1-git-send-email-fengchengwen@huawei.com/\n[2] https://github.com/bruce-richardson/dpdk/tree/dmadev-rfcs\n\nBruce Richardson (9):\n dmadev: add missing exports\n dmadev: change virtual addresses to IOVA\n dmadev: add dump function\n dmadev: remove xstats functions\n dmadev: drop cookie typedef\n dmadev: allow NULL parameters to completed ops call\n dmadev: stats structure updates\n drivers: add dma driver category\n app/test: add basic dmadev unit test\n\n app/test/meson.build | 2 +\n app/test/test_dmadev.c | 320 +++++++++++++++++++++++++++++++++++\n drivers/dma/meson.build | 11 ++\n drivers/meson.build | 1 +\n lib/dmadev/rte_dmadev.c | 66 ++------\n lib/dmadev/rte_dmadev.h | 204 +++++++---------------\n lib/dmadev/rte_dmadev_core.h | 16 +-\n lib/dmadev/rte_dmadev_pmd.h | 24 +--\n lib/dmadev/version.map | 7 +-\n 9 files changed, 425 insertions(+), 226 deletions(-)\n create mode 100644 app/test/test_dmadev.c\n create mode 100644 drivers/dma/meson.build\n\n--\n2.30.2" }
