Introduction
This page records the POSIX test results of Yocto 1.2. You can get more informations from POSIX test overall on Yocto. 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.
All POSIX test cases can be get at POSIX git repository.
The online POSIX specification could be viewed at IEEE Std 1003.1, 2004 Edition.
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

pa: 0x400fb000 pa_2: 0x40115000 Modification of the partial page at the end of an object is written out |
Test case map a file with size of 1/2 * page_size, then write char 'b' to next byte of 1/2 * page_size. Then try to re-mmap() the file and expect the byte next to of 1/2 * page_size should not be character 'b'. Test on all platforms are failed. The reason is after first mmap(), the mapped page for the file is cached in page cache. When do the 2nd or 3rd mmap() still get the same mapped page.
mmap() is a system call and implemented by mmap2(). Then the call sequence is mmap2() ==> sys_mmap_pgoff() ==> do_mmap_pgoff() ==> mmap_region() ==> file->f_op->mmap(). In ext3 file system, file->f_op->mmap() point to generic_file_mmap(). In generic_file_mmap(), assign the Page Fault Exception Handler to filemap_fault(). When access the Virtual Memory Area, page fault will occur and the run filemap_fault(). In filemap_fault(), kernel run find_get_page() to search the physical page in the page cache. |
