2018-09-17qmi_wwan: set DTR for modems in forced USB2 modeBjørn Mork1-7/+7
Recent firmware revisions have added the ability to force these modems to USB2 mode, hiding their SuperSpeed capabilities from the host. The driver has been using the SuperSpeed capability, as shown by the bcdUSB field of the device descriptor, to detect the need to enable the DTR quirk. This method fails when the modems are forced to USB2 mode by the modem firmware. Fix by unconditionally enabling the DTR quirk for the affected device IDs.

2018-09-17clk: x86: Stop marking clocks as CLK_IS_CRITICALHans de Goede1-7/+0
Commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the firmware"), which added the code to mark clocks as CLK_IS_CRITICAL, causes all unclaimed PMC clocks on Cherry Trail devices to be on all the time, resulting on the device not being able to reach S0i3 when suspended. The reason for this commit is that on some Bay Trail / Cherry Trail devices the r8169 ethernet controller uses pmc_plt_clk_4. Now that the clk-pmc-atom driver exports an "ether_clk" alias for pmc_plt_clk_4 and the r8169 driver has been modified to get and enable this clock (if present) the marking of the clocks as CLK_IS_CRITICAL is no longer necessary. This commit removes the CLK_IS_CRITICAL marking, fixing Cherry Trail devices not being able to reach S0i3 greatly decreasing their battery drain when suspended.

2018-09-17r8169: Get and enable optional ether_clk clockHans de Goede1-0/+33
On some boards a platform clock is used as clock for the r8169 chip, this commit adds support for getting and enabling this clock (assuming it has an "ether_clk" alias set on it). This is related to commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the firmware") which is a previous attempt to fix this for some x86 boards, but this causes all Cherry Trail SoC using boards to not reach there lowest power states when suspending. This commit (together with an atom-pmc-clk driver commit adding the alias) fixes things properly by making the r8169 get the clock and enable it when it needs it.

2018-09-17clk: x86: add "ether_clk" alias for Bay Trail / Cherry TrailHans de Goede1-0/+11
Commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the firmware") causes all unclaimed PMC clocks on Cherry Trail devices to be on all the time, resulting on the device not being able to reach S0i2 or S0i3 when suspended. The reason for this commit is that on some Bay Trail / Cherry Trail devices the ethernet controller uses pmc_plt_clk_4. This commit adds an "ether_clk" alias, so that the relevant ethernet drivers can try to (optionally) use this, without needing X86 specific code / hacks, thus fixing ethernet on these devices without breaking S0i3 support. This commit uses clkdev_hw_create() to create the alias, mirroring the code for the already existing "mclk" alias for pmc_plt_clk_3.

2018-09-17hv_netvsc: pair VF based on serial numberStephen Hemminger2-25/+36
Matching network device based on MAC address is problematic since a non VF network device can be creted with a duplicate MAC address causing confusion and problems. The VMBus API does provide a serial number that is a better matching method. Signed-off-by: Stephen Hemminger <sthemmin@microsoft.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-17PCI: hv: support reporting serial number as slot informationStephen Hemminger1-0/+37
The Hyper-V host API for PCI provides a unique "serial number" which can be used as basis for sysfs PCI slot table. This can be useful for cases where userspace wants to find the PCI device based on serial number. When an SR-IOV NIC is added, the host sends an attach message with serial number. The kernel doesn't use the serial number, but it is useful when doing the same thing in a userspace driver such as the DPDK. By having /sys/bus/pci/slots/N it provides a direct way to find the matching PCI device. There maybe some cases where serial number is not unique such as when using GPU's. But the PCI slot infrastructure will handle that. This has a side effect which may also be useful. The common udev network device naming policy uses the slot information (rather than PCI address).

The recent commit to always forward the VF MAC address to the PF for approval may not work if the PF driver or the firmware is older.

2018-09-17net: mvpp2: let phylink manage the carrier stateAntoine Tenart1-15/+6
Net drivers using phylink shouldn't mess with the link carrier themselves and should let phylink manage it. The mvpp2 driver wasn't following this best practice as the mac_config() function made calls to change the link carrier state. This led to wrongly reported carrier link state which then triggered other issues. This patch fixes this behaviour. But the PPv2 driver relied on this misbehaviour in two cases: for fixed links and when not using phylink (ACPI mode). The later was fixed by adding an explicit call to link_up(), which when the ACPI mode will use phylink should be removed. The fixed link case was relying on the mac_config() function to set the link up, as we found an issue in phylink_start() which assumes the carrier is off. If not, the link_up() function is never called. To fix this, a call to netif_carrier_off() is added just before phylink_start() so that we do not introduce a regression in the driver.

2018-09-15hwmon: (nct6775) Fix virtual temperature sources for NCT6796DGuenter Roeck1-6/+22
The following kernel log message is reported for the nct6775 driver on ASUS WS X299 SAGE. nct6775: Found NCT6796D or compatible chip at 0x2e:0x290 nct6775 nct6775.656: Invalid temperature source 11 at index 0, source register 0x100, temp register 0x73 nct6775 nct6775.656: Invalid temperature source 11 at index 2, source register 0x300, temp register 0x77 nct6775 nct6775.656: Invalid temperature source 11 at index 3, source register 0x800, temp register 0x79 nct6775 nct6775.656: Invalid temperature source 11 at index 4, source register 0x900, temp register 0x7b A recent version of the datasheet lists temperature source 11 as reserved. However, an older version of the datasheet lists temperature sources 10 and 11 as supported virtual temperature sources. Apparently the older version of the datasheet is correct, so list those temperature sources as supported. Virtual temperature sources are different than other temperature sources: Values are not read from a temperature sensor, but written either from BIOS or an embedded controller. As such, each virtual temperature has to be reported. Since there is now more than one temperature source, we have to keep virtual temperature sources in a chip-specific mask and can no longer rely on the assumption that there is only one virtual temperature source with a fixed index. This accounts for most of the complexity of this patch.

2018-09-14xen/gntdev: fix up blockable calls to mn_invl_range_startMichal Hocko1-11/+15
Patch series "mmu_notifiers follow ups". Tetsuo has noticed some fallouts from 93065ac753e4 ("mm, oom: distinguish blockable mode for mmu notifiers"). One of them has been fixed and picked up by AMD/DRM maintainer [1]. XEN issue is fixed by patch 1. I have also clarified expectations about blockable semantic of invalidate_range_end. Finally the last patch removes MMU_INVALIDATE_DOES_NOT_BLOCK which is no longer used nor needed. [1] http://lkml.kernel.org/r/20180824135257.GU29735@dhcp22.suse.cz This patch (of 3): 93065ac753e4 ("mm, oom: distinguish blockable mode for mmu notifiers") has introduced blockable parameter to all mmu_notifiers and the notifier has to back off when called in !blockable case and it could block down the road. The above commit implemented that for mn_invl_range_start but both in_range checks are done unconditionally regardless of the blockable mode and as such they would fail all the time for regular calls. Fix this by checking blockable parameter as well. Once we are there we can remove the stale TODO. The lock has to be sleepable because we wait for completion down in gnttab_unmap_refs_sync.

In the first iteration cpu_present is still true, in the second iteration cpu_present is false which causes get_cpu_device to return NULL. In case of cpu#0, cpu_online is apparently always true. Fix this crash by checking if the cpu can be hotplugged, which is false for a cpu that was just removed. Also check if the cpu was actually offlined by device_remove, otherwise leave the cpu_present state as it is. Rearrange to code to do all work with device_hotplug_lock held.

2018-09-14xen/balloon: add runtime control for scrubbing ballooned out pagesMarek Marczykowski-Górecki3-3/+14
Scrubbing pages on initial balloon down can take some time, especially in nested virtualization case (nested EPT is slow). When HVM/PVH guest is started with memory= significantly lower than maxmem=, all the extra pages will be scrubbed before returning to Xen. But since most of them weren't used at all at that point, Xen needs to populate them first (from populate-on-demand pool). In nested virt case (Xen inside KVM) this slows down the guest boot by 15-30s with just 1.5GB needed to be returned to Xen. Add runtime parameter to enable/disable it, to allow initially disabling scrubbing, then enable it back during boot (for example in initramfs). Such usage relies on assumption that a) most pages ballooned out during initial boot weren't used at all, and b) even if they were, very few secrets are in the guest at that time (before any serious userspace kicks in). Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also enabled by default), controlling default value for the new runtime switch.
