The weston runtime test is unreliable, depending on the execution speed
of its runner. Example of failure is [1], and success is [2]. This
commit improves the test in several ways, to make it more robust to
execution speed variations:
- The command started in background (weston, weston-simple-egl) are
now started in a subshell. This suppresses the job control messages
when they are stopped. Those messages could interfere with the parsing
of the output;
- Wait time are moved outside the emulator;
- The kernel argument vt.global_cursor_default=0 is added, to make sure
cursors are globally disabled, since the test use vkms display CRCs;
- The memory of the emulator is increased to 512M. This test uses cpio
initramfs, and the filesystem size increased;
- The vkms driver emulates a "vsync" event, but can generate a warning
when the system is too slow. This warning is printed on the console by
the klogd daemon in its default configuration. This commit adds the
overlay file /etc/default/klogd to limit only kernel emergency
messages to be printed on the console. This change fixes the failure
seen in [1] ;
- Some sleep time values were adjusted to run on a "performant" idle
host. Those values are not suitable in all situations. In the
meantime a generic retry mechanism is added in the test infra, this
commit adds a retry logic inspired from the test_flutter runtime
test.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
