2018-10-17kvm/x86 : add coalesced pio supportPeng Hao1-6/+10
Coalesced pio is based on coalesced mmio and can be used for some port like rtc port, pci-host config port and so on. Specially in case of rtc as coalesced pio, some versions of windows guest access rtc frequently because of rtc as system tick. guest access rtc like this: write register index to 0x70, then write or read data from 0x71. writing 0x70 port is just as index and do nothing else. So we can use coalesced pio to handle this scene to reduce VM-EXIT time. When starting and closing a virtual machine, it will access pci-host config port frequently. So setting these port as coalesced pio can reduce startup and shutdown time. without my patch, get the vm-exit time of accessing rtc 0x70 and piix 0xcf8 using perf tools: (guest OS : windows 7 64bit) IO Port Access Samples Samples% Time% Min Time Max Time Avg time 0x70:POUT 86 30.99% 74.59% 9us 29us 10.75us (+- 3.41%) 0xcf8:POUT 1119 2.60% 2.12% 2.79us 56.83us 3.41us (+- 2.23%) with my patch IO Port Access Samples Samples% Time% Min Time Max Time Avg time 0x70:POUT 106 32.02% 29.47% 0us 10us 1.57us (+- 7.38%) 0xcf8:POUT 1065 1.67% 0.28% 0.41us 65.44us 0.66us (+- 10.55%) Signed-off-by: Peng Hao <peng.hao2@zte.com.cn> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2018-10-17KVM: x86: hyperv: implement PV IPI send hypercallsVitaly Kuznetsov1-0/+7
Using hypercall for sending IPIs is faster because this allows to specify any number of vCPUs (even > 64 with sparse CPU set), the whole procedure will take only one VMEXIT. Current Hyper-V TLFS (v5.0b) claims that HvCallSendSyntheticClusterIpi hypercall can't be 'fast' (passing parameters through registers) but apparently this is not true, Windows always uses it as 'fast' so we need to support that.

2018-10-16f2fs: checkpoint disablingDaniel Rosenberg1-0/+5
Note that, it requires "f2fs: return correct errno in f2fs_gc". This adds a lightweight non-persistent snapshotting scheme to f2fs. To use, mount with the option checkpoint=disable, and to return to normal operation, remount with checkpoint=enable. If the filesystem is shut down before remounting with checkpoint=enable, it will revert back to its apparent state when it was first mounted with checkpoint=disable. This is useful for situations where you wish to be able to roll back the state of the disk in case of some critical failure.

2018-10-16FDDI: defza: Add support for DEC FDDIcontroller 700 TURBOchannel adapterMaciej W. Rozycki2-0/+59
Add support for the DEC FDDIcontroller 700 (DEFZA), Digital Equipment Corporation's first-generation FDDI network interface adapter, made for TURBOchannel and based on a discrete version of what eventually became Motorola's widely used CAMEL chipset. The CAMEL chipset is present for example in the DEC FDDIcontroller TURBOchannel, EISA and PCI adapters (DEFTA/DEFEA/DEFPA) that we support with the `defxx' driver, however the host bus interface logic and the firmware API are different in the DEFZA and hence a separate driver is required. There isn't much to say about the driver except that it works, but there is one peculiarity to mention. The adapter implements two Tx/Rx queue pairs. Of these one pair is the usual network Tx/Rx queue pair, in this case used by the adapter to exchange frames with the ring, via the RMC (Ring Memory Controller) chip. The Tx queue is handled directly by the RMC chip and resides in onboard packet memory. The Rx queue is maintained via DMA in host memory by adapter's firmware copying received data stored by the RMC in onboard packet memory. The other pair is used to communicate SMT frames with adapter's firmware. Any SMT frame received from the RMC via the Rx queue must be queued back by the driver to the SMT Rx queue for the firmware to process. Similarly the firmware uses the SMT Tx queue to supply the driver with SMT frames that must be queued back to the Tx queue for the RMC to send to the ring. This solution was chosen because the designers ran out of PCB space and could not squeeze in more logic onto the board that would be required to handle this SMT frame traffic without the need to involve the driver, as with the later DEFTA/DEFEA/DEFPA adapters. Finally the driver does some Frame Control byte decoding, so to avoid magic numbers some macros are added to <linux/if_fddi.h>. Signed-off-by: Maciej W.

2018-10-12net/ipv6: Add knob to skip DELROUTE message on device downDavid Ahern1-0/+8
Another difference between IPv4 and IPv6 is the generation of RTM_DELROUTE notifications when a device is taken down (admin down) or deleted. IPv4 does not generate a message for routes evicted by the down or delete; IPv6 does. A NOS at scale really needs to avoid these messages and have IPv4 and IPv6 behave similarly, relying on userspace to handle link notifications and evict the routes. At this point existing user behavior needs to be preserved. Since notifications are a global action (not per app) the only way to preserve existing behavior and allow the messages to be skipped is to add a new sysctl (net/ipv6/route/skip_notify_on_dev_down) which can be set to disable the notificatioons. IPv6 route code already supports the option to skip the message (it is used for multipath routes for example). Besides the new sysctl we need to pass the skip_notify setting through the generic fib6_clean and fib6_walk functions to fib6_clean_node and to set skip_notify on calls to __ip_del_rt for the addrconf_ifdown path.
