      cpufreq: intel_pstate: Always set max P-state in performance mode · 2f1d407a
      Rafael J. Wysocki 提交于
      The only times at which intel_pstate checks the policy set for
      a given CPU is the initialization of that CPU and updates of its
      policy settings from cpufreq when intel_pstate_set_policy() is
      invoked.
      
      That is insufficient, however, because intel_pstate uses the same
      P-state selection function for all CPUs regardless of the policy
      setting for each of them and the P-state limits are shared between
      them.  Thus if the policy is set to "performance" for a particular
      CPU, it may not behave as expected if the cpufreq settings are
      changed subsequently for another CPU.
      
      That can be easily demonstrated by writing "performance" to
      scaling_governor for all CPUs and then switching it to "powersave"
      for one of them in which case all of the CPUs will behave as though
      their scaling_governor were all "powersave" (even though the policy
      still appears to be "performance" for the remaining CPUs).
      
      Fix this problem by modifying intel_pstate_adjust_busy_pstate() to
      always set the P-state to the maximum allowed by the current limits
      for all CPUs whose policy is set to "performance".
      
      Note that it still is recommended to always change the policy setting
      in the same way for all CPUs even with this fix applied to avoid
      confusion.

      PM / suspend: Fix missing KERN_CONT for suspend message · 1adb469b
      Jon Hunter 提交于
      Commit 4bcc595c (printk: reinstate KERN_CONT for printing
      continuation lines) exposed a missing KERN_CONT from one of the
      messages shown on entering suspend. With v4.9-rc1, the 'done.' shown
      after syncing the filesystems no longer appears as a continuation but
      a new message with its own timestamp.
      
      [    9.259566] PM: Syncing filesystems ... [    9.264119] done.
      
      Fix this by adding the KERN_CONT log level for the 'done.' part of the
      message seen after syncing filesystems. While we are at it, convert
      these suspend printks to pr_info and pr_cont, respectively.

      After commit a4675fbc (cpufreq: intel_pstate: Replace timers with
      utilization update callbacks) the cpufreq governor callbacks may not
      be invoked on NOHZ_FULL CPUs and, in particular, switching to the
      "performance" policy via sysfs may not have any effect on them.  That
      is a problem, because it usually is desirable to squeeze the last
      bit of performance out of those CPUs, so work around it by setting
      the maximum P-state (within the limits) in intel_pstate_set_policy()
      upfront when the policy is CPUFREQ_POLICY_PERFORMANCE.

      arm/arm64: KVM: Map the BSS at HYP · c8ea0395
      Marc Zyngier 提交于
      When used with a compiler that doesn't implement "asm goto"
      (such as the AArch64 port of GCC 4.8), jump labels generate a
      memory access to find out about the value of the key (instead
      of just patching the code). The key itself is likely to be
      stored in the BSS.
      
      This is perfectly fine, except that we don't map the BSS at HYP,
      leading to an exploding kernel at the first access. The obvious
      fix is simply to map the BSS there (which should have been done
      a long while ago, but hey...).

      arm64: KVM: Take S1 walks into account when determining S2 write faults · 60e21a0e
      Will Deacon 提交于
      The WnR bit in the HSR/ESR_EL2 indicates whether a data abort was
      generated by a read or a write instruction. For stage 2 data aborts
      generated by a stage 1 translation table walk (i.e. the actual page
      table access faults at EL2), the WnR bit therefore reports whether the
      instruction generating the walk was a load or a store, *not* whether the
      page table walker was reading or writing the entry.
      
      For page tables marked as read-only at stage 2 (e.g. due to KSM merging
      them with the tables from another guest), this could result in livelock,
      where a page table walk generated by a load instruction attempts to
      set the access flag in the stage 1 descriptor, but fails to trigger
      CoW in the host since only a read fault is reported.
      
      This patch modifies the arm64 kvm_vcpu_dabt_iswrite function to
      take into account stage 2 faults in stage 1 walks. Since DBM cannot be
      disabled at EL2 for CPUs that implement it, we assume that these faults
      are always causes by writes, avoiding the livelock situation at the
      expense of occasional, spurious CoWs.
      
      We could, in theory, do a bit better by checking the guest TCR
      configuration and inspecting the page table to see why the PTE faulted.
      However, I doubt this is measurable in practice, and the threat of
      livelock is real.
