This series introduces a new rawdevice PMD which allows to manage userspace GPIOs and install custom GPIO interrupt handlers which bypass kernel. This is especially useful for applications that, besides providing standard dataplane functionality, want to have fast and low latency access to GPIO pin state. It'd be great to have that merged during 22.02 merge window. v3: - fix meson formatting - fix cnxk_gpio_process_buf() return value v2: - do not trigger irq by writing to /dev/mem, use ioctl() instead Tomasz Duszynski (10): raw/cnxk_gpio: add GPIO driver skeleton raw/cnxk_gpio: support reading default queue conf raw/cnxk_gpio: support reading queue count raw/cnxk_gpio: support queue setup raw/cnxk_gpio: support queue release raw/cnxk_gpio: support enqueuing buffers raw/cnxk_gpio: support dequeuing buffers raw/cnxk_gpio: support standard GPIO operations raw/cnxk_gpio: support custom irq handlers raw/cnxk_gpio: support selftest doc/guides/rawdevs/cnxk_gpio.rst | 195 +++++++ doc/guides/rawdevs/index.rst | 1 + drivers/raw/cnxk_gpio/cnxk_gpio.c | 633 +++++++++++++++++++++ drivers/raw/cnxk_gpio/cnxk_gpio.h | 33 ++ drivers/raw/cnxk_gpio/cnxk_gpio_irq.c | 216 +++++++ drivers/raw/cnxk_gpio/cnxk_gpio_selftest.c | 386 +++++++++++++ drivers/raw/cnxk_gpio/meson.build | 11 + drivers/raw/cnxk_gpio/rte_pmd_cnxk_gpio.h | 429 ++++++++++++++ drivers/raw/cnxk_gpio/version.map | 3 + drivers/raw/meson.build | 1 + 10 files changed, 1908 insertions(+) create mode 100644 doc/guides/rawdevs/cnxk_gpio.rst create mode 100644 drivers/raw/cnxk_gpio/cnxk_gpio.c create mode 100644 drivers/raw/cnxk_gpio/cnxk_gpio.h create mode 100644 drivers/raw/cnxk_gpio/cnxk_gpio_irq.c create mode 100644 drivers/raw/cnxk_gpio/cnxk_gpio_selftest.c create mode 100644 drivers/raw/cnxk_gpio/meson.build create mode 100644 drivers/raw/cnxk_gpio/rte_pmd_cnxk_gpio.h create mode 100644 drivers/raw/cnxk_gpio/version.map -- 2.25.1
