In order to select between the in-tree and OOT drivers for the single
driver, a cmdline parameter out-of-tree-drivers need be used. The
cmdline parameter out-of-tree-drivers will be set driver names that
these drivers will be used as the out of tree drivers. For example
"out-of-tree-drivers=ice,i40e,iavf", the OOT drivers ice, i40e, iavf
will be loaded by "insmod" command before udevd is started, and that
ensures that the OOT drivers will be loaded rather than the in-tree
drivers.
The default drivers will be the in-tree drivers if there is not
out-of-tree-drivers in the cmdline parameters or they are not set
correct.
1. Switch the single driver as the following step.
a) ice
* switch the ice driver to the OOT version
out-of-tree-drivers=ice
* switch the ice driver to the in-tree version
remove ice from out-of-tree-drivers or set any value except ice
b) i40e
* switch the i40e driver to the OOT version
out-of-tree-drivers=i40e
* switch the i40e driver to the in-tree version
remove i40e from out-of-tree-drivers or set any value except i40e
c) iavf
* switch the iavf driver to the OOT version
out-of-tree-drivers=iavf
* switch the iavf driver to the in-tree version
remove iavf from out-of-tree-drivers or set any value except iavf
2. Switch the bundle driver as the following step.
* switch the bundle drivers to the OOT version.
out-of-tree-drivers=ice,iavf,i40e
* switch the bundle drivers to the in-tree version
out-of-tree-drivers=
or
remove out-of-tree-drivers from the boot commandline.
or
out-of-tree-drivers=aaa,bb,xx(any value except ice,i40e,iavf)
3. Switch any two ones.
* switch ice and iavf to the OOT version.
out-of-tree-drivers=ice,iavf
* switch i40e and iavf to the OOT version.
out-of-tree-drivers=i40e,iavf
* switch to the in-tree version.
just remove driver name from out-of-tree-drivers or set any value
except ice, iavf and i40e.
Verification:
Switch drivers between the OOT and in-tree drivers.
- switch to the OOT drivers
1. Add cmdline parameter out-of-tree-drivers=ice,iavf,i40e
2. reboot
can switch to the OOT drivers for ice, iavf and i40e.
- switch to the in-tree drivers
1. Remove cmdline parameter out-of-tree-drivers
2. reboot
can switch to the in-tree drivers for ice, iavf and i40e.
- switch to the OOT ice driver(for iavf and i40e is same with ice)
1. Add cmdline parameter out-of-tree-drivers=ice
2. reboot
can switch to the OOT driver for ice
- switch to the OOT drivers for ice and iavf (for the combination of
the other two drivers are same with this one. )
1. Add cmdline parameter out-of-tree-drivers=ice,iavf
2. reboot
can switch to the OOT drivers for ice, iavf.
- Set the cmdline parameter out-of-tree-drivers=ice,iavf,aaa
It can switch to the OOT driver for ice and iavf.
