Certification Program | Linux Standard Base Conformance Release 1.2 |
Test Suite | lsb-runtime IA32 version 1.2.1-1 |

Specification | Linux Standard Base Specification for PPC32 Architecture 1.2 |
Problem Summary | Assumption of HZ=100 |
Problem Text | The T.execl_L 7 test is written with the assumption that when setting the timer value using the setitimer call that when the value is read back with getitimer that it will be *exactly* the same. For the values chosen this is may not be true when HZ!=100. SuSv2 allows for rounding up when the precision required for the timer value is more than the implementation supports. Although this problem was encountered on IA64 where HZ=1024 it is believed that it non HZ=100 IA32 systems will be out soon. |

Review Recommendation | Test Suite Deficiency (TSD) |
Review Response | Timers are accurate to +1/-1 clock ticks and so the tests should allow for this varience. Where the precision for a timer is more than that supported the specification allows rounding up. On this implementation under test,it is running at 1024khz, so 1 clock tick is 977 microseconds. It is recommended that a TSD be granted. |
