Subject: [PATCH net-next v10 0/4] ethtool: provide the dim profile fine-tuning channel
Date: Fri, 26 Apr 2024 00:59:44 +0800 [thread overview]
Message-ID: <20240425165948.111269-1-hengqi@linux.alibaba.com> (raw)
The NetDIM library provides excellent acceleration for many modern
network cards. However, the default profiles of DIM limits its maximum
capabilities for different NICs, so providing a way which the NIC can
be custom configured is necessary.
Currently, the way is based on the commonly used "ethtool -C".
Please review, thank you very much!
Changelog
=====
v9->v10:
- Collect dim related flags/mode/work into one place.
- Use rx_profile + tx_profile instead of four profiles.
- Add several helps.
- Update commit logs.
v8->v9:
- Fix the compilation error of conflicting names of rx_profile in
dim.h and ice driver: in dim.h, rx_profile is replaced with
dim_rx_profile. So does tx_profile.
v7->v8:
- Use kmemdup() instead of kzalloc()/memcpy() in dev_dim_profile_init().
v6->v7:
- A new wrapper struct pointer is used in struct net_device.
- Add IS_ENABLED(CONFIG_DIMLIB) to avoid compiler warnings.
- Profile fields changed from u16 to u32.
v5->v6:
- Place the profile in netdevice to bypass the driver.
The interaction code of ethtool <-> kernel has not changed at all,
only the interaction part of kernel <-> driver has changed.
v4->v5:
- Update some snippets from Kuba, Thanks.
v3->v4:
- Some tiny updates and patch 1 only add a new comment.
v2->v3:
- Break up the attributes to avoid the use of raw c structs.
- Use per-device profile instead of global profile in the driver.
v1->v2:
- Use ethtool tool instead of net-sysfs
Heng Qi (4):
linux/dim: move useful macros to .h file
ethtool: provide customized dim profile management
