[Xen-devel] [xen-4.4-testing test] 26937: regressions - trouble: broken/fail/pass

flight 26937 xen-4.4-testing real [real]

Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-i386-pair         3 host-install/src_host(3) broken REGR. vs. 26455
 test-amd64-i386-pair         4 host-install/dst_host(4) broken REGR. vs. 26455
 test-amd64-amd64-xl-qemuu-debianhvm-amd64 7 debian-hvm-install fail REGR. vs. 

Regressions which are regarded as allowable (not blocking):
 test-amd64-amd64-xl-qemut-winxpsp3  7 windows-install          fail like 26455

commit fb5f0c280b252597b052894498c9fac2037cedd7

    timers: set the deadline more accurately
    Program the timer to the deadline of the closest timer if it is further
    than 50us ahead, otherwise set it 50us ahead.  This way a single event
    fires on time rather than 50us late (as it would have previously) while
    still preventing too many timer wakeups in the case of having many
    timers scheduled close together.
    (where 50us is the timer_slop)

    x86: don't use VA for cache flush when also flushing TLB
    Doing both flushes at once is a strong indication for the address
    mapping to either having got dropped (in which case the cache flush,
    when done via INVLPG, would fault) or its physical address having
    changed (in which case the cache flush would end up being done on the
    wrong address range). There is no adverse effect (other than the
    obvious performance one) using WBINVD in this case regardless of the
    range's size; only map_pages_to_xen() uses combined flushes at present.
    This problem was observed with the 2nd try backport of d6cb14b3 ("VT-d:
    suppress UR signaling for desktop chipsets") to 4.2 (where ioremap()
    needs to be replaced with set_fixmap_nocache(); the now commented out
    __set_fixmap(, 0, 0) there to undo the mapping resulted in the first of
    the above two scenarios).

    AMD IOMMU: don't free page table prematurely
    iommu_merge_pages() still wants to look at the next level page table,
    the TLB flush necessary before freeing too happens in that function,
    and if it fails no free should happen at all. Hence the freeing must
    be done after that function returned successfully, not before it's
    being called.

    VT-d: fix mask applied to DMIBAR in desktop chipset XSA-59 workaround
    In commit  ("VT-d: suppress UR signaling for desktop chipsets")
    the mask applied to the value read from DMIBAR is to narrow, only the
    comment accompanying it was correct. Fix that and tag the literal
    number as "long" at once to avoid eventual compiler warnings.
    The widest possible value so far is 39 bits; all chipsets covered here
    but having less than this number of bits have the remaining bits marked
    reserved (zero), and hence there's no need for making the mask chipset

    ACPI/ERST: fix table mapping
    acpi_get_table(), when executed before reaching SYS_STATE_active, will
    return a mapping valid only until the next invocation of that funciton.
