POSIX-results

Introduction

This page records the POSIX test results of Yocto 1.2. The test suite is from ltp and version 20110915. Six platforms are included: qemu-arm qemu-ppc qemu-mips beagleboard mpc8315rdb routerstation. There are 1794 test cases in total, only failed items are list here.

Results and analysis

The results of groups SIG SEM THR TMR MSG TPS MEM are listed. Conclusion of some test cases have been given.

Value of clumn "status":

Bug: it is a bug and the test case needs to be fixed.

Ignore: the case is not appropriate for the hardware or linux

POSIX: that test case is in development, that causes the test fails

The low-priority thread should not run until the other threads stop running, unless the machine has more than NCPU processors. Redefine NCPU = sysconf(_SC_NPROCESSORS_CONF), testcase should pass	n/a
pthread_create/10-1	POSIX	qemu-arm beagleboard qemu-mips routerstation	Segmentation fault	test case use an uninitialized attributes object to case pthread_create() segmentation fault then catch the signal. But the uninitialized object is NOT invalid to pthread_create() all the time	n/a

timer_getoverrun/3-1	POSIX	qemu-arm beagleboard qemu-mips routerstation qemu-ppc mpc8315e		Just print something and then return UNTESTED	n/a
timer_getoverrun/2-3		qemu-arm beagleboard routerstation		"WR: Change CONFIG_HZ from 100 to 250 can solve this." The root cause is that these platform don't provide HIGH RESOLUTION TIMER. The value on platforms which test case can pass is only 1 nanosecond. But on qemuarm is 10000000 nanoseconds, on routerstation is 4000250 nanoseconds. After set CONFIG_HIGH_RES_TIMER=y for routerstation (CONFIG_HZ=250 has been set), test case passes. These 2 kernel configurations for qemuarm are not permitted.	n/a
clock_getcpuclockid/5-1	Ignore	qemu-arm beagleboard qemu-mips routerstation qemu-ppc mpc8315e	clock_getcpuclockid(1, ..) passed unexpectedly	Permission issue. When call clock_getcpuclockid() as a unpriviledge user to get process 'init' cpu time, it succeeds but expect fails with EPERM. This is not supported by Linux. In man page, it addresses EPERM " does not occur on Linux unless the kernel does not support obtaining the per-process CPU-time clock of another process."	n/a
