CHIPS AND TECH.65550 PCI DRIVER

For instance, the line. The xx MMIO mode has been implemented entirely from the manual as I don’t have the hardware to test it on. This option is only useful when acceleration can’t be used and linear addressing can be used. So for unexplained problems not addressed above, please try to alter the clock you are using slightly, say in steps of 0. By default it is assumed that there are 6 significant bits in the RGB representation of the colours in 4bpp and above.

This is a debugging option and general users have no need of it. This might further reduce the available memory. If you are having driver-related problems that are not addressed by this document, or if you have found bugs in accelerated functions, you can try contacting the Xorg team the anv driver maintainer can be reached at eich freedesktop.

The Chips and Technologies chipsets supported by this driver have one of three basic architectures.

When the chipset is capable of linear addressing and it has been turned off by default, this option can be used to turn it back on. For this reason, the maximum colour depth and resolution that can be supported in a dual cyips mode will be reduced compared to a single display channel mode. This chip is similar to the but has a 64bit memory bus as opposed to a 32bit bus.

For this reason a mode that is as close to VESA like as possible should be selected. This sets the physical memory base address of the linear framebuffer. For 24bpp on TFT screens, the server assumes that a xnd bus is being used.

It also includes a fully programmable dot clock and supports all types of flat panels. This can be fixed by using the ” 18BitBus ” option.

Try deleting theses options from cpi. There has been much confusion about exactly what the clock limitations of the Chips and Technologies chipsets are.

This option forces the two display channels to be used, giving independent refresh rates. The total memory requirements in this mode of operation is therefore similar to a 24bpp mode. In its current form, X can not take advantage of this second display channel.

For chipsets that support hardware cursors, this option enforces their use, even for cases that are known to cause problems on some machines. This is the first version of the of the ctxx that was capable of aand Hi-Color and True-Color. For other depths this option has no effect. Because the rendering is all done into a virtual framebuffer acceleration can not be used. Gamma correction at all depths and DirectColor visuals for depths of 15 or greater with the HiQV series of chipsets.

Otherwise it has the the same properties as the Firstly, the memory requirements of both heads must fit in the available memory. Note that this option only has an effect on TFT screens.

The servers solution to this problem is not to do doubling vertically. If this is a problem, a work around is to remove the ” HWcursor ” option.

So using this option on a xx chipset forces them to use MMIO for all communications. It chipw be noted that the dual channel display options of the require the use of additional memory bandwidth, as each display channel independently accesses the video memory.

Note that this option using the multimedia engine to its limit, and some manufacturers have set a default memory clock that will cause pixel errors with this option. This problem has been reported under UnixWare 1. As mentioned before, try disabling this option.

The driver is capable cnips driving both a CRT and a flat panel display.

If it is a standard mode and frequency that your screen should be able to handle, try to find different timings for a similar mode and frequency combination. This may be related to a bug in one of the accelerated functions, or a problem with the BitBLT engine.
