Tvia Linux/XFree86-4.3.0 Display Driver Version x4.3.0.3.00



Jan. 11, 2002





General Information

-------------------



1. Driver files: only one object file "tvia_drv.o"



2. Version: x4.3.0.3.00



3. Functions of the driver:



(1) The linear frame buffer support

(2) Hardware cursor support

(3) PAL/NTSC TV display modes

(4) All the color depths support of 8, 16, 24 bits per pixel

(5) Use of 2D hardware acceleration

(6) Functions of DGA and X-video extension

(7) Function of use frame buffer device



4. Supported hardware chips:



(1) Tvia CyberPro 2010 chip

(2) Tvia CyberPro 50xx chips

(3) Tvia CyberPro 52xx chips

(4) Tvia CyberPro 53xx chips



5. Platforms requirement:



(1) Intel X86 CPUs or compatible ones

(2) XFree86 4.3.0

(3) Tvia video BIOS



6. What's new in this version:



(1) New option "xvimg_dubblebuffer" in "Device" of "XF86Config"

(2) New option of "UseFBDev" in "Device" of "XF86Config"





7. Notes:

(1) Standard mode is "640x480" "800x600" "1024x768" "1280x1024" for 8, 16, 24

depth, "640x400" "1600x1200" for 8, 16 depth.

(2) Refresh frequence for standard mode is limited to 60Hz, 72Hz, 75Hz

as Tvia VGA BIOS can set. BIOS should support to set standard PC mode,

otherwise refresh frequence will not higher then 60Hz. Standard mode

"640x400" only have a refresh frequence of 60Hz.

(3) Driver use Tvia BIOS initialized value to indicate following video memory:

CyberPro50xx cards:

. Size -- 2M or 4M

. Style -- "256Kx32" or "512Kx32"

. Bus width -- 64 or 32 bit

CyberPro52xx and CyberPro53xx cards:

. Size -- 4M or 8M

. Style -- "1Mx16"

. Bus width -- 64 or 32 bit

If the Video Ram you used don't match below or driver works incorrectly,

you should use option to adjust it.

(4) The default video memory clock maybe too high for some Set-Top-Box.

In this case,the "MemClock" option can be used to decrease video memory

clock. While at high resolution like "1280x1024", "1600x1200", memory

clock should set to "85MHz" - "90MHz" and make virtual screen size the

same as the resolution. This will get good performance.

(5) Video memory type:

In case some cards have different video memory installed, the "HasSDRAM"

option is use to manual set the video memory type. You can specify the

Video memory type is SDRAM or SGRAM. Default set is CyberPro50xx use

SGRAM(4MB), CyberPro52xx, CyberPro53xx use SDRAM(8MB).





Installation

------------



1. Install XFree86 4.3.0 server environment:



If you don't yet have XFree86 4.3.0 server with your Linux, please

install it first:



(1) Downlaod the XFree86 4.3.0 source and unzip it into

"/usr/X11R6", so the subdirectory "/usr/X11R6/xc" is created.



(2) In "/usr/X11R6/xc", enter command "make World" -- it takes

quite a while to be finished.



(3) In "/usr/X11R6/xc", enter command "make install".



(4) Make a link if no link is already there by entering command

"ln -s /usr/X11R6/bin/XFree86 /usr/X11R6/bin/X".



2. Copy the driver "tvia_drv.o" into

"/usr/X11R6/lib/modules/drivers".

Copy the man page "tvia._man" to file

"/usr/X11R6/man/man4/tvia.4".



3. Generate or modify the configure file "XF86Config":



If you have never had the XFree86 4.3.0 configure file on your

machine, please run "xf86config" to generate one. When asked

about the display chip or card, please skip it. But the questions

about monitor, display modes, and so on should be answered.



(1) Make sure the display modes in section "Screen" is what you

want.



(2) Modify section "Device" as follows:



Section "Device"

Identifier "devname"

Driver "tvia"

EndSection



* Make sure item "Driver" has value "tvia".



* "devname" is the same string as in the item "Device" of section

"Screen".



* Some hardware infomation can be specified by the items below:



VideoRam -- in KBytes. Example:



VideoRam 4096



Membase -- physical address of the linear frame buffer. Example:



Membase xxxxxxxx



"x" stands for a hex digit



IOBase -- physical address of the memory mapped I/O.



* Some standard option lines are available:



Option "Noaccel" -- No hardware acceleration



Option "SWcursor" -- using software cursor, otherwise hardware cursor



(3) For TV display, you should add one of the following optional

mode lines in section "Device":



For CyberPro50xx and CyberPro53xx:

Option "cyberpro_tv_on" "ntsc_640x400"

(Available only for 8/16 bpp)

Option "cyberpro_tv_on" "ntsc_640x440"

(Available only for 8/16 bpp)

Option "cyberpro_tv_on" "ntsc_640x480"

Option "cyberpro_tv_on" "ntsc_640x480_u"

Option "cyberpro_tv_on" "ntsc_720x480"

Option "cyberpro_tv_on" "ntsc_856x480"

Option "cyberpro_tv_on" "pal_640x400"

(Available only for 8/16 bpp)

Option "cyberpro_tv_on" "pal_640x440"

(Available only for 8/16 bpp)

Option "cyberpro_tv_on" "pal_640x480"

Option "cyberpro_tv_on" "pal_720x480"

Option "cyberpro_tv_on" "pal_720x540"

Option "cyberpro_tv_on" "pal_720x576"

Option "cyberpro_tv_on" "pal_768x576"

Option "cyberpro_tv_on" "pal_800x600"

Option "cyberpro_tv_on" "pal_856x480"

Option "cyberpro_tv_on" "pal_976x576"

Option "cyberpro_tv_on" "pal_1024x576"



For CyberPro2010:

Option "cyberpro_tv_on" "ntsc_640x480"

Option "cyberpro_tv_on" "ntsc_640x480_u"

Option "cyberpro_tv_on" "pal_640x480"

Option "cyberpro_tv_on" "pal_720x540"

Option "cyberpro_tv_on" "pal_800x600"





* It's required to keep the mode "640x480" in the curren

subsection "Display" of section "Screen" for any TV display mode.



* It's not supported to change display mode dynamically in X

windows for TV display. If so, TV display mode is gone.



* For the underscan mode "ntsc_640x480_u", virtual screen must be

disabled for a correct display.



(4) To use frame buffer device, you should turn on the option "UseFBDev"

in section "Device":

Option "UseFBDev"

This will enable using frame buffer device driver. Be sure the the

proper fb driver has been load first.



(5) You also have other options in the section "Device":



* Options for memory style



You can specify various video ram styles by setting the following

options:



Option "VideoRamStyle" "256Kx4"

Option "VideoRamStyle" "256Kx16"

Option "VideoRamStyle" "512Kx6"

Option "VideoRamStyle" "1Mx16"

Option "VideoRamStyle" "128Kx16"

Option "VideoRamStyle" "256Kx32"

Option "VideoRamStyle" "512Kx32"



The default value is:



Option "VideoRamStyle" "512Kx32"



* Option for memory bus width



Video ram bus width can be specified by



Option "VideoRamBus32"



The default of memory bus width is 64 bit. This option

will set the video ram bus width to 32 bit. Normaly this

option will reduce the performance.



Note: Video ram style should be spicified according to the

video ram type.



* Option for memory clock



Option "MemClock" "Frequency"



Frequency option values consist of a real number that is

optionally followed by one of the following frequency

units:



Hz, k, kHz, M, MHz



For example:



Option "MemClock" "75MHz"



Default frequency is 75Mhz for 5xxx chip, 80Mhz for 2010 chip.





Note: At high resolution like 1024x768, 1280x1024, 1600x1200, set

virtual screen size same as the physical size, and "MemClock" to

"83-90MHz". This will get good performance.



* Option for improve video play quality



Option "xvimg_doublebuffer" "boolean"



Smooth the playing of media files and improve the video performance.



The default value is "off"
