[PATCH] Bluetooth: btusb: Add Dell XPS 13 9360 to btusb_needs_reset_resume_table

by Hans de Goede

The Dell XPS 13 9360 uses a QCA Rome chip which needs to be reset (and have its firmware reloaded) for bluetooth to work after suspend/resume.

[PATCH] Bluetooth: btusb: Only check needs_reset_resume DMI table for QCA rome chipsets

by Hans de Goede

Jeremy Cline correctly points out in rhbz#1514836 that a device where the QCA rome chipset needs the USB_QUIRK_RESET_RESUME quirk, may also ship with a different wifi/bt chipset in some configurations. If that is the case then we are needlessly penalizing those other chipsets with a reset-resume quirk, typically causing 0.4W extra power use because this disables runtime-pm. This commit moves the DMI table check to a btusb_check_needs_reset_resume() helper (so that we can easily also call it for other chipsets) and calls this new helper only for QCA_ROME chipsets for now.

Hi Greg, These two patches should probably be part of the 4.4 because ce59e48fdbad ("serial: mctrl_gpio: implement interrupt handling") backport. 4.9, 4.14 and 4.16 have these patches already in it.

[PATCH v4] KVM: lapic: remove APIC Timer periodic/oneshot spikes

by Anthoine Bourgeois

Since the commit "8003c9ae204e: add APIC Timer periodic/oneshot mode VMX preemption timer support", a Windows 10 guest has some erratic timer spikes. Here the results on a 150000 times 1ms timer without any load: Before 8003c9ae204e | After 8003c9ae204e Max 1834us | 86000us Mean 1100us | 1021us Deviation 59us | 149us Here the results on a 150000 times 1ms timer with a cpu-z stress test: Before 8003c9ae204e | After 8003c9ae204e Max 32000us | 140000us Mean 1006us | 1997us Deviation 140us | 11095us The root cause of the problem is starting hrtimer with an expiry time already in the past can take more than 20 milliseconds to trigger the timer function. It can be solved by forward such past timers immediately, rather than submitting them to hrtimer_start(). In case the timer is periodic, update the target expiration and call hrtimer_start with it. v2: Check if the tsc deadline is already expired. Thank you Mika. v3: Execute the past timers immediately rather than submitting them to hrtimer_start(). v4: Rearm the periodic timer with advance_periodic_target_expiration() a simpler version of set_target_expiration().
