Bumping the routerstationpro SRCREV for the following fix: mm/msync: tweak tmpfs patch for syscall msync Commit 1c3ae5441 "mm: msync: fix issues of sys_msync on tmpfs" fixes the problem that sys_msync fails with tmpfs on MIPS CPU which has feature "cache alias". But it makes POSIX test cases mlockall/3-6 3-7 fail on MIPS. Case mlockall/3-6 creates a share memory, and maps it to memory. fd = shm_open(SHM_NAME, O_RDWR|O_CREAT, S_IRUSR|S_IWUSR); foo = mmap(NULL, BUF_SIZE, PROT_WRITE, MAP_SHARED, fd, 0); Then calls mlockall to lock all of the virtual address space: if (mlockall(MCL_CURRENT) == -1) { At last tests whether the virtual address spaces are locked: page_ptr = (void*) ((long)foo - ((long)foo % page_size)); result = msync(page_ptr, page_size, MS_SYNC|MS_INVALIDATE); It espects msync returns -1 with EBUSY but returns 0. Case mlockall/3-7 creates a normal file to mmap, and it fails too. Tweak the patch to: 1 Moved the CONFIG_TMPFS block down in the loop so that the normal vma flag checking will perform. 2 There may be other VMAs in the list after this VMA which belongs to tmpfs file, and we should sync them after the tmpfs one. So remove the break loop clauses. Signed-off-by: Kang Kai <kai.kang@windriver.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> |

README
Poky ==== Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration. Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way. As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project. The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/community/documentation OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "") and contains only emulated machine support. For information about OpenEmbedded, see the OpenEmbedded website: http://www.openembedded.org/
