Subject: [dpdk-dev] [PATCH v6 0/6] Fail-safe\ethdev: fix removal handling	lack
Date: Thu, 18 Jan 2018 11:27:08 +0000	[thread overview]
Message-ID: <1516274834-19755-1-git-send-email-matan@mellanox.com> (raw)
In-Reply-To: <1516220357-13013-1-git-send-email-matan@mellanox.com>

There is time between the physical removal of the device until sub-device PMDs get a RMV interrupt. 
At this time DPDK PMDs and applications still don't know about the removal and may call sub-device control operation which should return an error.

This series adds new ethdev operation to check device removal, adds support for it in mlx PMDs, adjust ethdev APIs to return -EIO in case of removal and fixes the fail-safe bug of removal error report.

V2:
Remove ENODEV definition.
Remove checks from all mlx control commands.
Add new devop - "is_removed".
Implement it in mlx4 and mlx5.
Fix failsafe bug by the new devop.

V3:
Adjust ethdev APIs removal error report.
Change failsafe check to check eth_dev* return values.
Remove backporting of fail-safe patch.

V4:
Improve fail-safe internal API to adjust the actual error value as discussed.
Remove "Fixes" lines from fail-safe patch.
No changes in ethdev\mlx patches.

V5:
Rebase on top of master-net-mlx. 

V6:
Move ethdev new API to be EXPERIMENTAL.

Matan Azrad (6):
  ethdev: add devop to check removal status
  net/mlx4: support a device removal check operation
  net/mlx5: support a device removal check operation
  ethdev: adjust APIs removal error report
  ethdev: adjust flow APIs removal error report
  net/failsafe: fix removed device handling
