CHAPTER 7

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 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 the prompt to disable the Solaris screen saver.

To start SunVTS with vtsui, but without vtsk, add the host name to xhost as: xhost + hostname.

cg6 Subtests

TABLE 7-1 cg6

Subtests	Description
Cursor Test	cg6 visually checks the overlay registers of the RAMDAC. A pointer is drawn on the screen and moved 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, writing different patterns to each. 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 accessible to confirm that further TEC access is performed correctly.
FBC Test	Verifies that the Frame Buffer Controller logic is accessible to confirm that further FBC access is performed correctly.
Frame Buffer Test	Verifies that the frame buffer memory is working. A "walking ones" 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 placed 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.

TABLE 7-1 cg6

Subtests	Description
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 backward and forward. 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 2.1 User's Guide for details about frame buffer locking.

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 Functional test.

cg6 Command Line Syntax

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

TABLE 7-2 cg6

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(isable)	Enables/disables the window system locking option. See the section about Testing Multiple Frame Buffers in the SunVTS 2.1 User's Guide for details. Do not use when device is the window system display.
L	Enables the long TMRB test.
Passes=number	The number of passes to run; the default is 1.
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 MBytes is required.
