Secondly, the memory bandwidth of the video processor is shared between the two heads. Disabling hidden DRAM refresh may also help. By default it is assumed that there are 6 significant bits in the RGB representation of the colours in 4bpp and above. Legal values for this key are depth dependent. It has the same ID and is identified as a when probed.

Possibly useful if you wish to use an old workstation monitor. This support can be used to give a single display image on pcu screen with different refresh rates, or entirely different images on the two displays. The Chips and Technologies chipsets supported by this driver have one of three basic architectures.

Many LCD displays are incapable of using a 24bpp mode. The HiQV series of chips have three programmable clocks.

This sets the physical memory base address of the linear framebuffer. The x and WinGine chipsets amd capable of colour depths of 16 or 24bpp. These option individually disable the features of the XAA acceleration code that the Chips and Technologies driver uses. This option forces the second display to take a particular amount of memory. Leaving too little memory available for the cache will only have a detrimental effect on the graphics performance.

Options related to drivers can be present ttech.65550 the Screen, Device and Monitor sections and the Display subsections. The and have a 64bit memory bus and thus transfer 8 bytes every clock thus hence the 8while the other HiQV chipsets are 32bit and transfer 4 bytes per clock cycle hence the 4.

Legal values are 2 to inclusive. You can use the ” SetMClk ” option in your xorg.

For LCD modes, it is possible that your LCD panel requires chipz panel timings at the text console than with a graphics mode. In this case the driver divides the video processors dotclock limitation by the number of bytes per pixel, so that the limitations for the various colour depths are. However there is no reliable way of probing the memory clock used in these chipsets, pcii so a conservative limit must be taken for the dotclock limit.

For this reason the default behaviour of the server is to use the panel timings already installed in the chip. However careful use of this option might boost performance. This disables use of the hardware cursor provided by the chip.

It is possible that the chip could be misidentified, particular hcips to interactions with other drivers in the server. 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. For CRT’s you can also try to tweak the mode timings; try increasing twch.65550 second horizontal value somewhat. The current programmable clock will be given as the last clock in the list.

Similar to the but also incorporates “PanelLink” drivers. Cgips chip is specially manufactured for Toshiba, and so documentation is not widely available. Typical values for the size of the framebuffer will be bytes x panelbytes x panel and bytes x panel. Gamma correction at all depths and DirectColor visuals for depths of 15 or greater with the HiQV series of chipsets.

Hence I hope that this section will clear up the misunderstandings. If you exceed the maximum set by the memory clock, you’ll get corruption on the screen during graphics operations, as you will be starving the HW BitBlt engine of clock cycles.

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.

This chip is basically identical to the Therefore to use this option the server must be started in chipw 15 or 16bpp depth. This option allows the user to force the server the reprogram the flat panel clock independently of the modeline with HiQV chipset. Display might be corrupted!!!

This has been reported on some configurations. This has a different effect depending on the hardware on which it is used.
