2024-05-24vlib: improvement to automatic core pinninghsandid1-0/+9
Type: feature If 'main-core' is not specified, the main thread is pinned by default to the cpu it is running on during initialization. This change does not impact manual core-pinning, which requires the 'main-core' argument e.g. 'cpu {main-core x corelist-workers n}.

2024-05-22vlib: prevent some signals from being executed on workersGuillaume Solignac1-0/+12
Before this commit, SIGINT, SIGHUP and SIGTERM could be executed on the workers. Since those signals don't stop execution, it meant that atexit handlers (like the `vl_unmap_shmem`) could run while the main thread was still running, which can cause race conditions. To avoid that, we prevent workers from handling those signals. Type: fix Signed-off-by: Guillaume Solignac <gsoligna@cisco.com> Change-Id: I27a87d96a027d7423ced881a614427af4ab0f969
2024-05-06vlib: revert automatic core pinning changesHadi Rayan Al-Sandid1-64/+7
This reverts commit 71c32a898941e32b5d4f865b50fbe775560c582d. Type: fix Reason for revert: vnet pinning is not considered in this patch. This causes keywords 'workers' and 'skip-cores' to be broken, as well as keyword 'main-core auto' introduced in this patch. If this patch is ever reconsidered, it must account for vnet pinning fix in commit https://gerrit.fd.io/r/c/vpp/+/40711.

2024-03-29vlib: improve automatic core pinninghsandid1-7/+64
