[Qemu-devel] [PATCH 0/2] linux-user: fix eventfd()

[Laurent Vivier]

This patch series byte-swap the uint64_t data stream
of a file-descriptor opened with eventfd().

It allows to pass more LTP test cases:

eventfd01    1  TPASS  :  counter value matches required
eventfd01    2  TPASS  :  read failed with EAGAIN as expected
eventfd01    3  TPASS  :  counter value matches required
eventfd01    4  TPASS  :  write failed with EAGAIN as expected
eventfd01    5  TPASS  :  read failed with EINVAL as expected
eventfd01    6  TPASS  :  write failed with EINVAL as expected
eventfd01    7  TPASS  :  write failed with EINVAL as expected
eventfd01    8  TPASS  :  fd is set in readfds
eventfd01    9  TPASS  :  fd is not set in readfds
eventfd01   10  TPASS  :  fd is set in writefds
eventfd01   11  TPASS  :  fd is not set in writefds
eventfd01    1  TPASS  :  counter value matches required
eventfd01    2  TPASS  :  read failed with EAGAIN as expected
eventfd01    3  TPASS  :  counter value matches required
eventfd01    4  TPASS  :  write failed with EAGAIN as expected
eventfd01    5  TPASS  :  read failed with EINVAL as expected
eventfd01    6  TPASS  :  write failed with EINVAL as expected
eventfd01    7  TPASS  :  write failed with EINVAL as expected
eventfd01    8  TPASS  :  fd is set in readfds
eventfd01    9  TPASS  :  fd is not set in readfds
eventfd01   10  TPASS  :  fd is set in writefds
eventfd01   11  TPASS  :  fd is not set in writefds
eventfd01   12  TPASS  :  counter value write from child successful
eventfd01   13  TCONF  :  eventfd01.c:642: eventfd support is not available in 
AIO subsystem
eventfd01   14  TCONF  :  eventfd01.c:647: eventfd support is not available in 
AIO subsystem
eventfd01   15  TCONF  :  eventfd01.c:652: eventfd support is not available in 
AIO subsystem
