[PATCH] vhost: fix physical address mapping

From: Xuan Ding When choosing IOVA as PA mode, IOVA is likely to be discontinuous, which requires page by page mapping for DMA devices. To be consistent, this patch implements page by page mapping instead of mapping at the region granularity for both IOVA as VA and PA mode. Fixes: 7c61fa08b716 (

[PATCH v3 00/10] Add cnxk_gpio PMD

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

[PATCH v3 01/10] raw/cnxk_gpio: add GPIO driver skeleton
