[PATCH v1 0/1] integrate dmadev in vhost

Since dmadev is introduced in 21.11, to avoid the overhead of vhost DMA abstraction layer and simplify application logics, this patch integrates dmadev in vhost. To enable the flexibility of using DMA devices in different function modules, not limited in vhost, vhost doesn't manage DMA devices. Ap

[PATCH v1 1/1] vhost: integrate dmadev in asynchronous datapath

Since dmadev is introduced in 21.11, to avoid the overhead of vhost DMA abstraction layer and simplify application logics, this patch integrates dmadev in asynchronous data path. Signed-off-by: Jiayu Hu Signed-off-by: Sunil Pai G --- doc/guides/prog_guide/vhost_lib.rst | 70 - examples

[RFC PATCH 0/6] Fast restart with many hugepages

This patchset is a new design and implementation of [1]. # Problem Statement Large allocations that involve mapping new hugepages are slow. This is problematic, for example, in the following use case. A single-process application allocates ~1TB of mempools at startup. Sometimes the app needs to r

[RFC PATCH 1/6] doc: add hugepage mapping details

Hugepage mapping is a layer of EAL malloc builds upon. There were implicit references to its details, like mentions of segment file descriptors, but no explicit description of its modes and operation. Add an overview of mechanics used on ech supported OS. Convert memory management subsections from

[RFC PATCH 2/6] mem: add dirty malloc element support

EAL malloc layer assumed all free elements content is filled with zeros ("clean"), as opposed to uninitialized ("dirty"). This assumption was ensured in two ways: 1. EAL memalloc layer always returned clean memory. 2. Freed memory was cleared before returning into the heap. Clearing the memory can

[RFC PATCH 3/6] eal: refactor --huge-unlink storage

In preparation to extend --huge-unlink option semantics refactor how it is stored in the internal configuration. It makes future changes more isolated. Signed-off-by: Dmitry Kozlyuk --- lib/eal/common/eal_common_options.c | 9 + lib/eal/common/eal_internal_cfg.h | 8 +++- lib/eal/l

[RFC PATCH 4/6] eal/linux: allow hugepage file reuse

Linux EAL ensured that mapped hugepages are clean by always mapping from newly created files: existing hugepage backing files were always removed. In this case, the kernel clears the page to prevent data leaks, because the mapped memory may contain leftover data from the previous process that was u

[RFC PATCH 5/6] eal: allow hugepage file reuse with --huge-unlink

Expose Linux EAL ability to reuse existing hugepage files via --huge-unlink=never switch. Default behavior is unchanged, it can also be specified using --huge-unlink=existing for consistency. Old --huge-unlink switch is kept, it is an alias for --huge-unlink=always. Signed-off-by: Dmitry Kozlyuk

[RFC PATCH 6/6] app/test: add allocator performance benchmark

Memory allocator performance is crucial to applications that deal with large amount of memory or allocate frequently. DPDK allocator performance is affected by EAL options, API used and, at least, allocation size. New autotest is intended to be run with different EAL options. It measures performanc
