CHIPS F65550 PDF

Can be this chip a sample? I check the codes on the internet and other chips seems to have only B, B2, A Thank you. The DKPCI board (versions A, B, C) includes a number of resistor installation options allowing GPIO pins from the F or B devices to perform. This manual is copyrighted by Chips and Technologies, Inc.

The Chips and Technologies driver release in X11R7. With the release of XFree86 version 4. This t65550 must be considered work in progress, and those users wanting stability are encouraged to use the older XFree86 3. However this version of the Chips and Technologies driver has many new features and bug fixes that might make users prefer to use this version.

Chips and Technologies – Wikipedia

Gamma correction at all depths and DirectColor visuals for depths of 15 or greater with the HiQV series of chipsets. This document attempts to discuss the features of this driver, the options useful in configuring it and the known problems.

Most of the Chips and Technologies chipsets are supported by this driver to some degree. The Chips and 6f5550 chipsets supported by this driver have one of three basic architectures. A basic architecture, the WinGine architecture which is a modification on this basic architecture and a completely new HiQV architecture.

This chip is basically identical to the It has the same ID and is identified as a when probed. See ct for details. This is a very similar chip to the However it additionally has cips ability for mixed 5V and 3. This d65550 the first chip of the ctxx series to support fully programmable clocks. Otherwise it has the the same properties as the This is the first version of the of the ctxx that was capable of supporting Hi-Color and True-Color. It also includes a fully programmable dot clock and supports all types of flat panels.

This chip is specially manufactured for Toshiba, and so documentation is not widely available. It is believed that this is really just a with a chops maximum dot-clock of 80MHz. This chip is similar to chkpsbut it also includes XRAM support and supports the higher dot clocks of the It often uses external DAC’s and programmable clock chips to supply additional functionally. None of these are currently supported within the driver itself, so many cards will only have limited support.

Linear addressing is not supported for this card in the driver. This is a more advanced version of the WinGine chip, with specification very similar to the x series of chips. However there are many differences at a cuips level. A similar level of acceleration to the is included for this driver. This chip is similar to the but has a 64bit memory bus as opposed to a 32bit bus. It also has higher limits on the maximum memory and pixel clocks Max Ram: Similar to the but has chlps higher maximum memory and pixel clocks.

Similar to the but also incorporates “PanelLink” drivers. This serial link allows an LCD screens to be located up to m from the video processor. The following options are of particular interest to the Chips and Technologies driver. Chops are therefore a wide variety of possible forms for all options. The forms given below are the preferred f56550. Options related to drivers can be present in the Screen, Device and Monitor sections and the Display subsections.

The order of precedence is Display, Screen, Monitor, Device. Option “NoAccel” This option will disable the use of any accelerated functions. This chi;s will override the detected amount of video memory, and pretend the given amount of memory is present on the card.

F665550 default linear addressing is used on all chips where it can be set up automatically. The fhips is for depths of 1 or 4bpp where linear addressing is turned off by default. It is possible to turn the linear addressing off with this option. 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. 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.

Note that linear addressing at 1 and 4bpp is not guaranteed to work correctly. This sets the physical memory base address of the linear framebuffer.

Typically this is probed correctly, but if you believe it to be mis-probed, this option might help. Also for non PCI machines specifying this force the linear base address to be this value, reprogramming the video processor to suit.

Note that for the this f6550 required as the base address can’t be correctly v65550. For chipsets that support hardware cursors, this option enforces their use, even for cases that are known to cause problems on some machines.

Note that it is overridden by the ” SWcursor ” option. Hardware vhips effectively speeds all graphics operations as the job of ensuring that the cursor remains on top is now given to the hardware.

It also reduces the effect of cursor flashing during graphics operations. This disables use of the hardware cursor provided by the chip. Try this if the cursor seems to have problems. The flat panel timings are related to the panel size and not the size of the mode specified in xorg. For this reason the default behaviour of the server is to use the panel timings already installed in the chip. The user can force the panel timings to t65550 recalculated from the modeline with this option.

However the panel size will still be probed.

For some machines the LCD panel size is incorrectly probed from the registers. This option forces the LCD panel size to be overridden by the modeline display sizes. This will prevent the use of a mode that is a different size than the panel.

Information for Chips and Technologies Users

Before using this check that the server reports an incorrect panel chils. This option can be used in conjunction with the option “UseModeline” to program all the panel timings using the modeline values.

When the size 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. A ” letterbox ” effect with no stretching can be achieved using this option.

When the size of the mode used is less than the panel size, the default behaviour of the server is to align the left cuips edge of the display with the left hand edge of the chipd. Using this option the mode can be centered in the screen. For the chips either using the WinGine or basic architectures, the chips generates a number of fixed clocks internally. With the chips and later or thethe default is to use the programmable clock for all clocks.

It is possible to use the fixed clocks supported by the chip instead by using this option. Typically this will give you some or all of the clocks The current programmable clock will be given as the last clock in the list. On a cold-booted system this might be the appropriate value to use at the text console see the ” TextClockFreq ” optionas many flat panels will need a dot clock different than the default to synchronise. The programmable clock makes this option obsolete and so it’s use isn’t recommended.

It is completely ignored for HiQV chipsets. Except for the HiQV chipsets, it is impossible for the server to read the value of the currently used frequency for the text console when using programmable clocks. Therefore the server uses a default value of This allows the user to select a different clock for the server to use when returning to the text console. In general the LCD panel clock should be set independently of the f6550 supplied.

This option allows the user to force the server the reprogram the flat panel clock independently of the modeline with HiQV chipset. The four options are for 8bpp or less, 16, 24 or 32bpp LCD panel clocks, where the options above set the clocks to 65MHz. The HiQV series of chips have three programmable clocks. The first two are usually loaded with These options can be used to force a particular clock index to be used.

This has a different effect depending on the hardware on which it is used. It is enabled by default for machines since the blitter can not be used otherwise. The xx chipsets can use MMIO for all communications with the video processor.

So using this option on a xx chipset forces them to use MMIO for all communications. This option sets the centering and stretching to the BIOS default values. It overrides the options “LcdCenter” and “NoStretch”. For 24bpp on TFT screens, the server assumes that a 24bit bus is being used. This can result in a reddish tint to 24bpp mode. This option, selects an 18 bit TFT bus.

For other depths this option has no effect. It is possible that the chip could be misidentified, particular due to interactions with other drivers in the server. It is possible to force the server to identify a particular chip with this option.
