Hi Subrata,
This has been tested on PPC440 and PPC405 PowerPC targets below are the
results :
---------------------------------------------------
<<<test_start>>>
tag=remap_file_pages01 stime=1248547976
cmdline="remap_file_pages01"
contacts=""
analysis=exit
<<<test_output>>>
remap_file_pages01 1 TPASS : Non-Linear shm file OK
remap_file_pages01 2 TPASS : Non-Linear /tmp/ file OK
<<<execution_status>>>
initiation_status="ok"
duration=0 termination_type=exited termination_id=0 corefile=no
cutime=18 cstime=13
<<<test_end>>>
<<<test_start>>>
tag=remap_file_pages02 stime=1248547976
cmdline="remap_file_pages02"
contacts=""
analysis=exit
<<<test_output>>>
remap_file_pages02 1 TPASS : remap_file_pages(2) expected failure; Got
errno - EINVAL : start does not refer to a valid mapping created with the
MAP_SHARED flag
remap_file_pages02 2 TPASS : remap_file_pages(2) expected failure; Got
errno - EINVAL : start is invalid
remap_file_pages02 3 TPASS : remap_file_pages(2) expected failure; Got
errno - EINVAL : size is invalid
remap_file_pages02 4 TPASS : remap_file_pages(2) expected failure; Got
errno - EINVAL : prot is invalid
<<<execution_status>>>
initiation_status="ok"
duration=0 termination_type=exited termination_id=0 corefile=no
cutime=0 cstime=1
<<<test_end>>>
-------------------------------------------------------
Or else other option to make these test cases pass on these target is to
modify the kernel config options :
Change of TASK_SIZE from 0x80000000 to 0xc0000000. A workaround is to
set these config options to
revert back to the old TASK_SIZE:
CONFIG_ADVANCED_OPTIONS=y
CONFIG_TASK_SIZE_BOOL=y
CONFIG_TASK_SIZE=0x80000000
Thanks,
-Srikanth
