      tpm: reduce polling time to usecs for even finer granularity · 424eaf91
      Nayna Jain authored
      The TPM burstcount and status commands are supposed to return very
      quickly [2][3]. This patch further reduces the TPM poll sleep time to usecs
      in get_burstcount() and wait_for_tpm_stat() by calling usleep_range()
      After this change, performance on a system[1] with a TPM 1.2 with an 8 byte
      burstcount for 1000 extends improved from ~10.7 sec to ~7 sec.
      [1] All tests are performed on an x86 based, locked down, single purpose
      closed system. It has Infineon TPM 1.2 using LPC Bus.
      [2] From the TCG Specification "TCG PC Client Specific TPM Interface
      Specification (TIS), Family 1.2":
      "NOTE : It takes roughly 330 ns per byte transfer on LPC. 256 bytes would
      take 84 us, which is a long time to stall the CPU. Chipsets may not be
      designed to post this much data to LPC; therefore, the CPU itself is
      stalled for much of this time. Sending 1 kB would take 350 μs. Therefore,
      even if the TPM_STS_x.burstCount field is a high value, software SHOULD
      be interruptible during this period."
      [3] From the TCG Specification 2.0, "TCG PC Client Platform TPM Profile
      (PTP) Specification":
      "It takes roughly 330 ns per byte transfer on LPC. 256 bytes would take
      84 us. Chipsets may not be designed to post this much data to LPC;
      therefore, the CPU itself is stalled for much of this time. Sending 1 kB
      would take 350 us. Therefore, even if the TPM_STS_x.burstCount field is a
      high value, software should be interruptible during this period. For SPI,
      assuming 20MHz clock and 64-byte transfers, it would take about 120 usec
      to move 256B of data. Sending 1kB would take about 500 usec. If the
      transactions are done using 4 bytes at a time, then it would take about
      1 msec. to transfer 1kB of data."

       "Another set of x86 related updates:

           was noticed by Arnd Bergman in course of his ongoing y2038 work.
           GLIBC seems to have non broken private copies of these headers so
           this went unnoticed.
         - Two microcode fixlets which address some more fallout from the
           recent modifications in that area:
            - Unconditionally save the microcode patch, which was only saved
              when CPU_HOTPLUG was enabled causing failures in the late
              loading mechanism
            - Make the later loader synchronization finally work under all
              circumstances. It was exiting early and causing timeout failures
              due to a missing synchronization point.
         - Do not use mwait_play_dead() on AMD systems to prevent excessive
           power consumption as the CPU cannot go into deep power states from
         - Address an annoying sparse warning due to lost type qualifiers of
           the vmemmap and vmalloc base address constants.
         - Prevent reserving crash kernel region on Xen PV as this leads to
           the wrong perception that crash kernels actually work there which
           is not the case. Xen PV has its own crash mechanism handled by the

      <linux/stringhash.h>: fix end_name_hash() for 64bit long · 19b9ad67
      Amir Goldstein authored
      The comment claims that this helper will try not to loose bits, but for
      64bit long it looses the high bits before hashing 64bit long into 32bit
      int.  Use the helper hash_long() to do the right thing for 64bit long.
      For 32bit long, there is no change.
      All the callers of end_name_hash() either assign the result to
      qstr->hash, which is u32 or return the result as an int value (e.g.
      full_name_hash()).  Change the helper return type to int to conform to
      its users.
      [ It took me a while to apply this, because my initial reaction to it
        was - incorrectly - that it could make for slower code.
        After having looked more at it, I take back all my complaints about
        the patch, Amir was right and I was mis-reading things or just being
        I also don't worry too much about the possible performance impact of
        this on 64-bit, since most architectures that actually care about
        performance end up not using this very much (the dcache code is the
        most performance-critical, but the word-at-a-time case uses its own
        hashing anyway).
        So this ends up being mostly used for filesystems that do their own
        degraded hashing (usually because they want a case-insensitive
        comparison function).
        A _tiny_ worry remains, in that not everybody uses DCACHE_WORD_ACCESS,
        and then this potentially makes things more expensive on 64-bit
        architectures with slow or lacking multipliers even for the normal
        That said, realistically the only such architecture I can think of is
        PA-RISC. Nobody really cares about performance on that, it's more of a
        "look ma, I've got warts^W an odd machine" platform.
        So the patch is fine, and all my initial worries were just misplaced
        from not looking at this properly.   - Linus ]

      Pull char/misc driver fixes from Greg KH:
       "Here are some small char and misc driver fixes for 4.17-rc3
        A variety of small things that have fallen out after 4.17-rc1 was out.
        Some vboxguest fixes for systems with lots of memory, amba bus fixes,
        some MAINTAINERS updates, uio_hv_generic driver fixes, and a few other
        minor things that resolve problems that people reported.
        The amba bus fixes took twice to get right, the first time I messed up
        applying the patches in the wrong order, hence the revert and later
        addition again with the correct fix, sorry about that.
        All of these have been in linux-next with no reported issues"

        There's a kobject WARN() removal to make syzkaller a lot happier about
        some "normal" error paths that it keeps hitting, which should reduce
        the number of false-positives we have been getting recently.
        There's also some fimware test and documentation fixes, and the
        coredump() function signature change that needed to happen after -rc1
        before drivers started to take advantage of it.
