Frame Buffer, GX, GX+ and TGX Options Test (cg6)

The cg6 test verifies the cgsix frame buffer and the graphics options offered with most SPARC^(TM) based workstations and servers. This test stresses the frame buffer with the subtests described below.

---

Note - Disable all screen savers before testing any graphics device. Type xset s off at a UNIX prompt to disable the Solaris screen saver.

To start SunVTS with vtsui, but without vtsk, you must add the hostname to xhost as:

xhost + <hostname>.

---

• Cursor Test visually checks the overlay registers of the RAMDAC. A pointer is drawn on the screen and moved around to predetermined locations. There is a problem if the pointer disappears. This visual test ensures that the overlay is working properly.
• Fast Copy in Double Buffer Test Mode creates two full-size screen raster images in double buffer mode. Different patterns are written to each of them. The hidden buffer is copied to the visible buffer, and the data is compared. An error message is returned if there are inconsistencies. Then the buffer is flipped and the process is repeated.

---

Note - This test only applies to Sun Microsystems GX+ graphic accelerators with double-buffering capacity.

---

• TEC Test verifies that the Transformation Engine and Cursor control logic are being accessed. This confirms that further TEC access is performed correctly.
• FBC Test verifies that the Frame Buffer Controller logic is being accessed. This confirms that further FBC access is performed correctly.
• Frame Buffer Test verifies that the frame buffer memory is working. A walking 1 pattern is written to memory, with a specific color signifying one of eight bits. The screen is divided into eight equally wide vertical stripes. A walking one is written to each stripe, causing eight iterations of these stripes. The value written is read back and checked. If the values do not match, an error is reported.
• Screen Test Using Blits draws blocks of color and performs blit transfers to other portions of the screen. First, the entire screen is drawn with cyan, then a black block is put in the upper left corner. This subtest blits this block on the upper right, lower right, and lower left corners, then or's the whole image.
• Blit Test draws a block of data and blit into a location at the bottom right rectangle.
• Line Test draws lines on the screen in different colors with different data values. The data is read back and compared with the expected values. An error is returned in the case of a mismatch.
• Polygon Test draws hourglass-shaped polygons on the screen, using the four vertices. After all the polygons are rendered in the video memory, they are read back and the data compared with expected values. If there is a mismatch, an error is displayed.
• Colormap Test loads all 256 locations in the color map with a greyscale, both backwards and forwards. This means decreasing values are loaded to all R, G, and B values.

---

Note - If the system being tested has a monochrome or greyscale monitor, visual color problems are undetectable.

FB Locking

See the section about Testing Frame Buffers in the SunVTS 2.0 User's Guide for details about frame buffer locking.

Figure 6-1 cg6

cg6 Test Modes

Due to the nature of graphic tests, reading from or writing to the frame buffer during graphic tests will disturb user operation. This test is only available in offline mode.

Connectivity Mode Not applicable for this test.

Online Mode Not applicable for this test.

Offline Mode The cg6 test verifies the cgsix frame buffer (GX, GX+ or TGX) offered with most SPARC TM based workstations and servers. The subtests are described in the first section of this chapter.

cg6 Command Line Syntax

/opt/SUNWvts/bin/cg14test standard_arguments -o dev=device_name,
lock=E(nable)/D(isable),L,Passes=number,I

Argument	Explanation
dev=device_name	Specifies the path of the cg14 device file to be tested; for example: /dev/fbs/device_name
lock=E(nable)/D(is able)	Enables/disables the window system locking option. See the section about Testing Multiple Frame Buffers in SunVTS 2.0 User's Guide for details. Do not use when device is the window system display.
L	Enables the long TMRB test.
Passes=number	Indicates the number of passes to run; the default is 1 pass.
I	Enables optional driver ioctl tests for cursor. Note: Do not move the mouse during the cg14test when you run this option.

Note - Extra swap space of 5 MB is required.
