  • 2a715fd01   ANDROID: sched/tracing: Print task status in sched_migrate_task ... Browse Code »

    A task can migrate either while it is waking or while it
    is running via load balancer. Print the task status
    i.e running or not in sched_migrate_task. This helps in
    counting the different types of migrations without relying
    on other trace events.

    Add a tracepoint for pause and resume which measures the
    duration of time to perform the entire operation, the
    cpus acted upon with this event, and the current state
    of the active cpu mask. This should be sufficient
    for testing pause performance.

    Like other filesystem does, we introduce a new file f2fs.h in path of
    include/uapi/linux/, and move f2fs-specified ioctl interface definitions

    developer only need to include the new header file rather than
    copy & paste definitions from fs/f2fs/f2fs.h.

  • 9889f08de   ANDROID: trace: Add trace points for tasklet entry/exit ... Browse Code »

    Tasklets are supposed to finish their work quickly and
    should not block the current running process, but it is not
    guaranteed that. Currently softirq_entry/exit can be used to
    know total tasklets execution time, but not helpful to track
    individual tasklet's execution time. With that we can't find
    any culprit tasklet function, which is taking more time.

    Add {hi}-tasklet_entry/exit trace point support to track
    individual tasklet execution.

    If inode gets evicted due to memory pressure, we have to remove it
    from the fast commit list. However, that inode may have uncommitted
    changes that fast commits will lose. So, just fall back to full
    commits in this case. Also, rename the fast commit ineligiblity reason
    from "EXT4_FC_REASON_MEM" to "EXT4_FC_REASON_MEM_NOMEM" for better
    expression.

  • f86726a69   afs: Fix afs_invalidatepage to adjust the dirty region ... Browse Code »

    Fix afs_invalidatepage() to adjust the dirty region recorded in
    page->private when truncating a page. If the dirty region is entirely
    removed, then the private data is cleared and the page dirty state is
    cleared.

    Without this, if the page is truncated and then expanded again by truncate,
    zeros from the expanded, but no-longer dirty region may get written back to
    the server if the page gets laundered due to a conflicting 3rd-party write.

    It mustn't, however, shorten the dirty region of the page if that page is
    still mmapped and has been marked dirty by afs_page_mkwrite(), so a flag is
    stored in page->private to record this.

  • 185f0c707   afs: Wrap page->private manipulations in inline functions ... Browse Code »

    The afs filesystem uses page->private to store the dirty range within a
    page such that in the event of a conflicting 3rd-party write to the server,
    we write back just the bits that got changed locally.

    However, there are a couple of problems with this:

    (1) I need a bit to note if the page might be mapped so that partial
    invalidation doesn't shrink the range.

    (2) There aren't necessarily sufficient bits to store the entire range of
    data altered (say it's a 32-bit system with 64KiB pages or transparent
    huge pages are in use).

    So wrap the accesses in inline functions so that future commits can change
    how this works.

    Also move them out of the tracing header into the in-directory header.
    There's not really any need for them to be in the tracing header.

    Pull KVM updates from Paolo Bonzini:
    "For x86, there is a new alternative and (in the future) more scalable
    implementation of extended page tables that does not need a reverse
    map from guest physical addresses to host physical addresses.

    For now it is disabled by default because it is still lacking a few of
    the existing MMU's bells and whistles. However it is a very solid
    piece of work and it is already available for people to hammer on it.

    Other updates:

    ARM:
    - New page table code for both hypervisor and guest stage-2
    - Introduction of a new EL2-private host context
    - Allow EL2 to have its own private per-CPU variables
    - Support of PMU event filtering
    - Complete rework of the Spectre mitigation

    PPC:
    - Fix for running nested guests with in-kernel IRQ chip
    - Fix race condition causing occasional host hard lockup
    - Minor cleanups and bugfixes

    x86:
    - allow trapping unknown MSRs to userspace
    - allow userspace to force #GP on specific MSRs
    - INVPCID support on AMD
    - nested AMD cleanup, on demand allocation of nested SVM state
    - hide PV MSRs and hypercalls for features not enabled in CPUID
    - new test for MSR_IA32_TSC writes from host and guest
    - cleanups: MMU, CPUID, shared MSRs
    - LAPIC latency optimizations ad bugfixes"
