2016-12-01docs-rst: parse-headers.pl: cleanup the documentationMauro Carvalho Chehab2-126/+12
Keeping both rst and in-file documentation in sync can be harsh. So, simplify the script's internal documntation to a bare minimum, and add a mention to the ReST file with its full documentation. This way, a quick help is still available at the command line, while the complete one is maintained at the ReST format. As we won't be using pad2rst anymore, do a cleanup at the ReST file.

2016-11-30tcp: SOF_TIMESTAMPING_OPT_STATS option for SO_TIMESTAMPINGFrancis Yan1-0/+10
This patch exports the sender chronograph stats via the socket SO_TIMESTAMPING channel. Currently we can instrument how long a particular application unit of data was queued in TCP by tracking SOF_TIMESTAMPING_TX_SOFTWARE and SOF_TIMESTAMPING_TX_SCHED. Having these sender chronograph stats exported simultaneously along with these timestamps allow further breaking down the various sender limitation. For example, a video server can tell if a particular chunk of video on a connection takes a long time to deliver because TCP was experiencing small receive window. It is not possible to tell before this patch without packet traces. To prepare these stats, the user needs to set SOF_TIMESTAMPING_OPT_STATS and SOF_TIMESTAMPING_OPT_TSONLY flags while requesting other SOF_TIMESTAMPING TX timestamps. When the timestamps are available in the error queue, the stats are returned in a separate control message of type SCM_TIMESTAMPING_OPT_STATS, in a list of TLVs (struct nlattr) of types: TCP_NLA_BUSY_TIME, TCP_NLA_RWND_LIMITED, TCP_NLA_SNDBUF_LIMITED. Unit is microsecond.

2016-11-28Documentation: devicetree: clarify usage of the RGMII phy-modesMartin Blumenstingl1-4/+20
RGMII requires special RX and/or TX delays depending on the actual hardware circuit/wiring. These delays can be added by the MAC, the PHY or the designer of the circuit (the latter means that no delay has to be added by PHY or MAC). There are 4 RGMII phy-modes used describe where a delay should be applied: - rgmii: the RX and TX delays are either added by the MAC (where the exact delay is typically configurable, and can be turned off when no extra delay is needed) or not needed at all (because the hardware wiring adds the delay already). The PHY should neither add the RX nor TX delay in this case. - rgmii-rxid: configures the PHY to enable the RX delay. The MAC should not add the RX delay in this case. - rgmii-txid: configures the PHY to enable the TX delay. The MAC should not add the TX delay in this case. - rgmii-id: combines rgmii-rxid and rgmii-txid and thus configures the PHY to enable the RX and TX delays. The MAC should neither add the RX nor TX delay in this case. Document these cases in the ethernet.txt documentation to make it clear when to use each mode. If applied incorrectly one might end up with MAC and PHY both enabling for example the TX delay, which breaks ethernet TX traffic on 1000Mbit/s links.

All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: David S. Miller <davem@davemloft.net>

The ARM specifies that the system counter "must be implemented in an always-on power domain," and so we try to use the counter as a source of timekeeping across suspend/resume. Unfortunately, some SoCs (e.g., Rockchip's RK3399) do not keep the counter ticking properly when switched from their high-power clock to the lower-power clock used in system suspend.

Pull KVM fixes from Radim Krčmář: "ARM: - Fix handling of the 32bit cycle counter - Fix cycle counter filtering x86: - Fix a race leading to double unregistering of user notifiers - Amend oversight in kvm_arch_set_irq that turned Hyper-V code dead - Use SRCU around kvm_lapic_set_vapic_addr - Avoid recursive flushing of asynchronous page faults - Do not rely on deferred update in KVM_GET_CLOCK, which fixes #GP - Let userspace know that KVM_GET_CLOCK is useful with master clock; 4.9 changed the return value to better match the guest clock, but didn't provide means to let guests take advantage of it" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: kvm: x86: merge kvm_arch_set_irq and kvm_arch_set_irq_inatomic KVM: x86: fix missed SRCU usage in kvm_lapic_set_vapic_addr KVM: async_pf: avoid recursive flushing of work items kvm: kvmclock: let KVM_GET_CLOCK return whether the master clock is in use KVM: Disable irq while unregistering user notifier KVM: x86: do not go through vcpu in __get_kvmclock_ns KVM: arm64: Fix the issues when guest PMCCFILTR is configured arm64: KVM: pmu: Fix AArch32 cycle counter access
2016-11-19kvm: kvmclock: let KVM_GET_CLOCK return whether the master clock is in usePaolo Bonzini1-0/+11
Userspace can read the exact value of kvmclock by reading the TSC and fetching the timekeeping parameters out of guest memory. This however is brittle and not necessary anymore with KVM 4.11. Provide a mechanism that lets userspace know if the new KVM_GET_CLOCK semantics are in effect, and---since we are at it---if the clock is stable across all VCPUs.

The iowait is not reliable by reading from /proc/stat, so this method to get iowait is not suggested. And we mark it in the document. Signed-off-by: Cao Jin <caoj.fnst@cn.fujitsu.com> Signed-off-by: Chao Fan <fanc.fnst@cn.fujitsu.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
