---|---|
Display (module0) |
Click Enable to display visual patterns.
Three subtests call the SPAM library and display pictures to verify the integrity of a subset of the kernel and the SPAM libraries through the SPARCstation 10 SX video system. These routines are ported from the SPAM demonstration programs. All subtests in this module are skipped if the cg14 frame buffer does not exist, or if the VRAM is disabled.
One of the following subtests displays screens between other subtests. This helps you determine whether the system is hung or if sxtest is running.
rect_test: The screen is filled with random rectangles. The rectangles are drawn in CHUNKY_XBGR mode if 32-bit mode OpenWindows is running. If not, they are drawn in CHUNKY_C8 mode with the SPAM library routine sl_rect_fill_32.
shaa: A picture of shaded lines is drawn in CHUNKY_BGR mode with the SPAM library routines sl_line_shaa_32, sl_span_load_8, and sl_rect_fill_8. NOTE: The shaa test is skipped if the test is running on an 8-bit window.
lines -- The screen is filled with lines of various colors. These lines are drawn in CHUNKY_XBGR mode if 32-bit mode OpenWindows is running; If not, they are drawn in CHUNKY_C8 mode with SPAM library routine sl_line_fill_8. |
