Subject: [PATCH v2 0/4] refactor the ringtest testing for ptr_ring
Date: Tue, 20 Jul 2021 10:21:45 +0800 [thread overview]
Message-ID: <1626747709-34013-1-git-send-email-linyunsheng@huawei.com> (raw)
tools/include/* has a lot of abstract layer for building
kernel code from userspace, so reuse or add the abstract
layer in tools/include/ to build the ptr_ring for ringtest
testing.
The same abstract layer can be used to build the ptr_ring
for ptr_ring benchmark app too, see [1].
1. https://lkml.org/lkml/2021/7/1/275
V2:
1. rebased on the Eugenio's patchset and split patch 1 to
more reviewable ones.
2. only add the interface used by ringtest, so that the
added code can be built and tested.
3. cpu_relax() only support x86 and arm64 now.
4. use 64 bytes as the default SMP_CACHE_BYTES.
Yunsheng Lin (4):
tools headers UAPI: add cache aligning related macro
tools headers UAPI: add kmalloc/vmalloc related interface
tools headers UAPI: add cpu_relax() implementation for x86 and arm64
tools/virtio: use common infrastructure to build ptr_ring.h
