This change excludes already loaded and linked libraries from this check

7 years agoFix streaming(memcpy) performance on Cortex-A7
Chitti Babu Theegala [Thu, 15 Dec 2016 20:43:28 +0000 (02:13 +0530)]
Fix streaming(memcpy) performance on Cortex-A7

Stream-mode detection for L1 in A7-core is failing for
non cache-line-size (non 64 byte) aligned addresses.
This leads to destination data getting cached unnecessarily.
This A7 issue is confirmed by ARM

This issue is solved by aligning destination address to 64 byte before
entering the loop in memcpy routine.
Though we get lower score for micro_bench memcpy when L1 cache is bypassed,
it is desirable since it avoids unnecessary eviction of other process data
from L1 which is good for overall system performance.

Higher micro_bench memcpy numbers for < 64byte alignment shows good numbers
but this is at the cost of L1 cache pollution. During memcpy/memset,
unnecessary data is filled in L1 cache, this causes eviction of other
process data from L1.
For example during msmset(0), L1 cache gets filled with 0s which should be
avoided.

Additionally, there is another issue with cortex A7 that impacts performance
for all alignments / all Android Wear versions:
Store Buffer on A7 is 32 byte which limits the 32-byte back to back stores.
In the current implementation back to back 32bytes writes is causing CPU stalls.
This issue can be solved by interleaved Loads and Stores.
This helps in avoiding CPU stalls during memcpy by utilizing efficiently the
A7 internal load and store buffers.

Update timezone data to 2016g.

The 2016g release of the tz code and data is available. It reflects the
following changes, which were either circulated on the tz mailing list
or are relatively minor technical or administrative changes:

  Changes to future time stamps

    Turkey switched from EET/EEST (+02/+03) to permanent +03,
    effective 2016-09-07.  (Thanks to Burak AYDIN.)  Use "+03" rather
    than an invented abbreviation for the new time.

    New leap second 2016-12-31 23:59:60 UTC as per IERS Bulletin C 52.
    (Thanks to Tim Parenti.)

  Changes to past time stamps

    For America/Los_Angeles, spring-forward transition times have been
    corrected from 02:00 to 02:01 in 1948, and from 02:00 to 01:00 in
    1950-1966.

    For zones using Soviet time on 1919-07-01, transitions to UT-based
    time were at 00:00 UT, not at 02:00 local time.  The affected
    zones are Europe/Kirov, Europe/Moscow, Europe/Samara, and
    Europe/Ulyanovsk.  (Thanks to Alexander Belopolsky.)

  Changes to past and future time zone abbreviations

    The Factory zone now uses the time zone abbreviation -00 instead
    of a long English-language string, as -00 is now the normal way to
    represent an undefined time zone.

    Several zones in Antarctica and the former Soviet Union, along
    with zones intended for ships at sea that cannot use POSIX TZ
    strings, now use numeric time zone abbreviations instead of
    invented or obsolete alphanumeric abbreviations.  The affected
    zones are Antarctica/Casey, Antarctica/Davis,
    Antarctica/DumontDUrville, Antarctica/Mawson, Antarctica/Rothera,
    Antarctica/Syowa, Antarctica/Troll, Antarctica/Vostok,
    Asia/Anadyr, Asia/Ashgabat, Asia/Baku, Asia/Bishkek, Asia/Chita,

    Asia/Yerevan, Etc/GMT-14, Etc/GMT-13, Etc/GMT-12, Etc/GMT-11,
    Etc/GMT-10, Etc/GMT-9, Etc/GMT-8, Etc/GMT-7, Etc/GMT-6, Etc/GMT-5,

    Etc/GMT+9, Etc/GMT+10, Etc/GMT+11, Etc/GMT+12, Europe/Kaliningrad,
    Europe/Minsk, Europe/Samara, Europe/Volgograd, and
    Indian/Kerguelen.  For Europe/Moscow the invented abbreviation MSM
    was replaced by +05, whereas MSK and MSD were kept as they are not
    our invention and are widely used.

  Changes to zone names

    Rename Asia/Rangoon to Asia/Yangon, with a backward compatibility link.

Fix tzdata loading.

Android uses one large file of tzdata, so the "read up to the maximum
possible length of a valid tzfile" code in upstream localtime.c is
broken: there is always data after the current tzfile (even the
last tzfile is followed by the zone.tab data). This patch passes the
exact length through to the read(2) call so we don't over-read, rather
than have to rewrite upstream code that measures back from the "end" of
the tzfile.

The old code failed the existing time.strftime_null_tm_zone test after
updating to tzdata2016g.
