Subject: [PATCH 1/4] block: cgroups, kconfig, build bits for BFQ-v7r11-4.7.0
|
||||
|
||||
Update Kconfig.iosched and do the related Makefile changes to include
|
||||
kernel configuration options for BFQ. Also increase the number of
|
||||
policies supported by the blkio controller so that BFQ can add its
|
||||
own.

Subject: [PATCH] igb: Allow to remove administratively set MAC on VFs
|
||||
|
||||
Before libvirt modifies the MAC address and vlan tag for an SRIOV VF
|
||||
for use by a virtual machine (either using vfio device assignment or
|
||||
macvtap passthru mode), it saves the current MAC address and vlan tag
|
||||
so that it can reset them to their original value when the guest is
|
||||
done. (libvirt can't leave the VF MAC set to the value used by the
|
||||
now-defunct guest (since it may be started again later using a
|
||||
different VF), but it certainly shouldn't just pick any random value,
|
||||
either. So it saves the state of everything prior to using the VF, and
|
||||
resets it to that.)
|
||||
|
||||
The igb driver initializes the MAC addresses of all VFs to
|
||||
00:00:00:00:00:00, and reports that when asked (via an RTM_GETLINK
|
||||
netlink message, also visible in the list of VFs in the output of "ip
|
||||
link show"). But when libvirt attempts to restore the MAC address back
|
||||
to 00:00:00:00:00:00 (using an RTM_SETLINK netlink message) the kernel
|
||||
responds with "Invalid argument".
|
||||
|
||||
However, to allow libvirt to revert to the original state, we need a
|
||||
way to remove the administrative set MAC on a VF, to allow normal host
|
||||
operation again, and to reset/overwrite the VF MAC via VF netdev.
|
||||
|
||||
This patch implements the aforementioned scenario by allowing to set
|
||||
the VF MAC to 00:00:00:00:00:00 via RTM_SETLINK on the PF.
|
||||
igb_ndo_set_vf_mac resets the IGB_VF_FLAG_PF_SET_MAC flag to 0,
|
||||
so it's possible to reset the VF MAC back to the original value via
|
||||
the VF netdev.

The expanded microarchitectures include:

* AMD Family 10h (Barcelona)
|

* Intel 6th Gen Core i3/i5.i7 (Skylake)
|
||||
|
||||
It also offers to compile passing the 'native' option which, "selects the CPU
|
||||
to generate code for at compilation time by determining the processor type of
|
||||
the compiling machine. Using -march=native enables all instruction subsets
|
||||
supported by the local machine and will produce code optimized for the local
|
||||
machine under the constraints of the selected instruction set."[3]
|
||||
|
||||
MINOR NOTES
|
||||
This patch also changes 'atom' to 'bonnell' in accordance with the gcc v4.9
|
||||
changes. Note that upstream is using the deprecated 'match=atom' flags when I
|
||||
believe it should use the newer 'march=bonnell' flag for atom processors.[2]
|
||||
|
||||
It is not recommended to compile on Atom-CPUs with the 'native' option.[4] The
|
||||
recommendation is to the 'atom' option instead.
|
||||
|
||||
BENEFITS
|
||||
Small but real speed increases are measurable using a make endpoint comparing
|
||||
a generic kernel to one built with one of the respective microarchs.
