CHIPS AND TECH.65550 PCI DRIVER

Also check the BIOS settings. The clock code can be fooled into giving a different and perhaps more stable clock by simply changing the clock value slightly. The xx MMIO mode has been implemented entirely from the manual as I don’t have the hardware to test it on. With this option all of the graphics are rendered into a copy of the framebuffer that is keep in the main memory of the computer, and the screen is updated from this copy. It also reduces the effect of cursor flashing during graphics operations.

This option sets the centering and stretching to the BIOS default values. This is useful for the chipset where the base address of the linear framebuffer must be supplied by the user, or at depths 1 and 4bpp. This can result in a reddish tint to 24bpp mode.

The Xserver assumes that the framebuffer, if used, will be at the top of video ram. This is a debugging option and general users have no need of it.

It also reduces the effect of cursor flashing during graphics operations. Using this option the mode can be centered in the screen.

Note that linear addressing at 1 and 4bpp is not guaranteed to work correctly. This is a driver limitation that might be relaxed in the future. So if you have a virtual screen size set chi;s x using a x at 8bpp, you use kB for the mode. The programmable clock makes this option obsolete and so it’s use isn’t recommended.

Information for Chips and Technologies Users

If this is not true then the screen will appear to have a reddish tint. The Chips and Technologies chipz supported by this driver have one of three basic architectures.

By default linear addressing is used on all chips where it can be set up automatically. When the chios of the mode used is less than the panel size, the default behaviour of the server is to stretch the mode in an attempt to fill the screen.

In pcj way the expensive operation of reading back to contents of the screen is never performed and the performance is improved. Many DSTN screens use the top of video ram to implement a frame accelerator. There has been much confusion about exactly what the clock limitations of the Chips and Technologies chipsets are. Try reducing the clock.

Note that it is overridden by the ” SWcursor ” option. The exception is for depths of 1 or 4bpp where linear addressing is turned off by default. Alternatively the user can use the ” TextClockFreq ” option described above to select a different clock for the text console.

If you see such display corruption, and you have this warning, your choices are to reduce the refresh rate, colour depth or resolution, or increase the speed of the memory tedh.65550 with the the ” SetMClk ” option described above. This sets the physical memory base address of the linear framebuffer. However use caution with these options, because there is no guarantee that driving the video processor beyond it capabilities won’t cause damage.

The chipset has independent display channels, that can be configured to support independent refresh rates on the flat panel and on the CRT. This can be done by using pxi external frame buffer, or incorporating the framebuffer at the top of video ram depending on the particular implementation.

Which results in the x mode only expanded to x This allows the user to select a different clock for the server to use when returning to the text console.

This disables use of the hardware cursor provided by the chip. By default the two display share equally the available memory.

Using this option, when the virtual desktop is scrolled away from the zero position, the snd cache becomes visible. Also check the BIOS settings.

It might affect some other SVR4 operating systems as well. As mentioned before, try disabling this option. However there are many older machines, particularly those with x screen or larger, that need to reprogram the panel timings.
