Re: [Linux-fbdev-users] Framebuffer - what is it?

From: David Klempner <klempner@im...> - 2008-11-19 22:04:04

fbdev is the primary in-kernel generic video system.

It is an alternative to the driver layer in X; that can only be used by
X, which is very heavyweight -- and then X can use fbdev instead if the
user just wants something that works.

fbdev also provides fbcon, which is an alternative to the simple text
mode console. Yes, this means that we get a console with (potentially)
arbitrary resolutions and fonts. That's actually really useful when you
are debugging a problem on a system causing X to not come up.

More importantly, on some platforms the more basic video consoles do not
work -- this is more common in embedded or esoteric (relative to x86)
platforms.

I don't think there is a single silver bullet -- but X and its clients
are not the only software on the system that want a video display.

I think the main use is so that X or other GUI apps can run on smaller embedded
systems that don't have any hardware accelerated video chip. You just bit-bang
pixels in a memory area (the framebuffer) and it appears on the display.

[Linux-fbdev-users] Framebuffer - what is it?

From: Chris Jones <cga2000@gm...> - 2008-11-19 02:43:58

I'm finding it difficult to "place" the framebuffer project.

What is/are its objective(s)?

Is it meant to be an alternative to X?

Is it just a generic low-level package that complements X in the event
no specific driver for a given video chip is not available?

Most people appear to think in a vague kind of way that the framebuffer
is just a bunch of tricks that let you use a higher resolution on the
linux console.

This seems to make little sense in the light of all the activity on the
fbdev development list where patches (both corrections & enhancements)
are published on a daily basis.

I just cannot imagine a number of high-end programmers spending their
time providing enhancements for the linux console - especially when you
consider how very few applications can actually run in that environment
and usually with some feature loss as compared to running them in an
xterm, for instance.

There seems to be something much more important at stake than the linux
console but after reading the few available docs and being subscribed to
both fbdev lists for a number of years, I still don't get it.

:-(

Apologies if this post makes little sense to some/most.. I'm hitting a
wall and I guess that I am just too ignorant to ask the right questions.

Hopefully someone more knowledgeable will help reformulate and maybe
come up with the question(s) I am incapable of asking.

[Linux-fbdev-users] How to write LCD driver for framebuffer?

From: Duan ZhiQiang <magicduanzq@gm...> - 2008-10-06 10:58:11

Attachments: Message as HTML

Hi,

I have project which will support 11"LCD with 1280x545 screen size in Linux
system,
In this project, we will use framebuffer device for X window system.

So, for support 11"LCD, which modules should I need to modify?
Should I need to write a framebuffer driver to support 11"LCD?
Is there any source code to reference?
Can somebody tell me how to start it?

Many Thanks.

Duan

[Linux-fbdev-users] disableing screen saver

Attachments: Message as HTML

Hello all

When we are in console of linux ( and not in X-Window) the console have screen saver ( that will blank the console after a period of time).

How we can disable this screen saver ( of console frame buffer) ?

Thanks

The minimum is to set the flag FBINFO_HWACCEL_COPYAREA
into fb_info->flags. If you do not announce the accelerated copyarea
function it is not used (the imageblit is preferred).
If you defined both flags FBINFO_HWACCEL_IMAGEBLIT and
FBINFO_HWACCEL_COPYAREA you have to specify the
FBINFO_READS_FAST to prefer the copyarea. As no of this flag is
set in the imxfb driver the imageblit is used.

Simply, the console use them for scrolling. The tridentfb still
uses the copyarea for scrolling on families other then Blade3d.

Yes. I can recheck if you want, but there is a measurable speed difference 
if you define FBINFO_READS_FAST or not on the 3Dfx hardware.

Please check this threads:
http://marc.info/?l=linux-fbdev-devel&m=117852288316471&w=2
http://marc.info/?l=linux-fbdev-devel&m=117852288316471&w=2

and some threads around. Since then the copyarea is much faster.

The imageblit is preferred over copyarea is it is usually faster. The fillrect 
is always used.

Please check the constants mentioned above and try again.

Its not architecture specific.

> I did used the copyarea on some other drivers (tridentfb, pm2fb).

How did you use them?

> The tdfxfb driver uses now copyarea function for console scrolling.

Are you sure, this function will be called? I wrote two drivers for ARM and 
x86 graphics hardware and provide a copyarea function for both of them. The 
console framework ignores both. Only the fillrect and imageblit function is 
used from the frambuffer console code.

In driver/video/console/fbcon.c I always fail in function fbcon_scroll(). 
The "dir" switch/case never reaches one of the "switch (p->scrollmode)" 
statements.

I do not have atmel hardware to test. I did used the copyarea on some other drivers (tridentfb, pm2fb). The tdfxfb driver uses now copyarea function for console scrolling. I will inspect out the atmel driver and give you some hints.

Did you ever get the framework to use the copyarea function the driver 
provides? I tried it several times and this function was never called. 
Independent from any flags I set or clear.

A few more pieces of information:

Xorg reports:

X.org VideoRAM: 4096 kByte

The motherboard is an Intel 440LX, and the kernel is using the Debian 
config options, with 686 architecture and "low latency desktop" selected.

Hi every body!
I use STMicroelectronics product (set top box with STLinux 2.2) and I want
to install the framebuffer driver. I followed instruction in STLinux.com to
build necessary kernel modules cfbXXXX.ko. But I invoke the makefile I get
errors  in the txt file.
Has any one an idea what can I do?

[Linux-fbdev-users] OT: best display controller for ARM9 processor...

From: Gianluca <gianlucarenzi@ep...> - 2008-07-29 15:21:11

Hello list,
I know this question will be a little off-topic, but I think this list can help me in the right way.
Our customer is asking an embedded solution with a LCD display 10.4" up to 640x480-18bits to
play Xvid, DivX, mpeg4/h264 video stream.
Actually we have an embedded system equipped with samsung s3c2442@... (64Mb SDRAM / 128Mb Flash)
and it plays quite good 320x200 divx movies with pcm audio with mplayer using FBDev.
It DOES NOT HAVE an FPU, so all decoding is done in software and it takes about 80% of cpu time!
CPU is running at 300Mhz, Memory Bus at 100Mhz and external bus is running at 50Mhz.

Now, one of our customers is asking a video-player to run a 25fps 640x480 video stream *with* an
overlay option, just to display some characters on top of this display. Is it correct we need
a ~16Mb/sec of cpu to memory bandwith? ((640x480 px times 2 (16bit)) times 25 (fps) )

We would like to re-use our existing hardware knowledge, so it is preferred to be linked against
a samsung SoC processor thru an external bus expansion.

Do you know some hardware manufacturers (linux driver compatible) that deliver such power?

Best regards,

[Linux-fbdev-users] problem about color palettes

From: a a <batic62@ya...> - 2008-06-08 15:27:52

Hello all

I have a problem in programming with frame buffer
device as follows:


i use the following code in my program for setting the
color palettes:
    if ( 0> ioctl( fb, FBIOPUTCMAP, &p_cmap))
        perror( "" ) ;

but it does not work.
What is wrong ? and how can i set the palettes of
color ?

Re: [Linux-fbdev-users] matroxfb: supports gamma on primary VGA out?

Thanks very much for clearing this up.

I guess doing the correction in software is easy enough with 3x 8-bit
look-up tables (if this is what you mean by '8bit only'?)  But of course
it's less than ideal to have to modify applications like this. Luckily
the apps I care about most (fbxine and mplayer) already support
software gamma correction, and the CPU overhead isn't too great, so no
need to install an X server just yet. :-)

Thanks again.
Stephen

These ioctls control only TV output - MATROXFB_S_*TVO*CTRL.  If you want 
VGA gamma correction, do it in software - Matrox G400/450/550 is 8bit 
only, so it is not very interesting to push this task to hardware if you 
are using 24/32bpp mode.

[Linux-fbdev-users] matroxfb: supports gamma on primary VGA out?

From: Stephen Kell <srk31@sr...> - 2008-05-18 20:58:59

I'm trying to set gamma correction on the primary VGA output of my
Matrox G400 dual-head, using matroxfb with kernel 2.6.24. 

Using matroxset, the ioctl completes successfully, but there is no
effect.

stephen@...:~$ strace matroxset -f /dev/fb0 -o 0 -c 0x980910 18 2>&1 | grep ioctl 
ioctl(3, MATROXFB_G_TVOCTRL or VIDIOC_G_CTRL, 0xbfaec7d4) = 0
ioctl(3, MATROXFB_S_TVOCTRL or VIDIOC_S_CTRL, 0xbfaec7d4) = 0

I've tried other controls (contrast, brightness etc.), with a range of
arguments, and none has any visible effect.

Looking in matroxfb_base.c, it looks like the implementation of
VIDIOC_S_CTRL is hardwired to use output 1. However, if I try with
CRTC1 duplicated to output 1 (using matroxset -f /dev/fb0 -o 1 128), it
still shows no effect. 

Is this a bug, or am I missing something? Thanks for any help.

[Linux-fbdev-users] Problem with aty128fb on 2.6.25

From: Witold Filipczyk <witekfl@po...> - 2008-05-03 12:51:24

Hi,
aty18fb doesn't work on 2.6.25. It didn't work on 2.6.24.5, either.
It worked on 2.6.24.3. aty128fb is compiled as a module.
At http://republika.pl/rkd/dump_config.tar.bz2 there are my config
and dump.png. The screen doesn't look exactly like this,
but similar, especially top part of the screen.
How can I make it work?

[Linux-fbdev-users] ezfb-10.00 New Release

From: James Lehman <james@ak...> - 2008-03-21 23:53:43

Look for ezfb-10.00 here:
http://freshmeat.net/

Released 03-21-2008

If you follow their links to my site, I get more manna or chi or something.
I just submitted the new release, so it won't appear until they review it.

Well, here it is! This is the full version of LaserBoy in C++ source code!
It compiles and runs on just about any Linux machine running a frame buffer
enabled kernel. That would include a session of Knoppix running in a
VirtualPC on a Windows Machine!

LaserBoy is a full featured laser vector art workstation application capable
of reading, drawing, generating, animating, manipulating, writing, etc...
ILDA, DXF, Bitmap, palette, C++, and WAVE files.

Most importantly, LaserBoy generates standard multi-channel wave files,
which, when played from an appropriate sound device (in any OS) will produce
the complex signals necessary to directly drive a standard RGB ILDA laser
projection system.

It is a hardware independent, industry standard file format, 24-bit color,
open source software solution for laser projection.

I plan to continue to add to this project, as time permits. The next big
step is to port it to SDL (http://www.libsdl.org/) so that it may run an
just about any OS.

If you are interested in this project, please feel free to contact me
directly. Contact information is on my website.

[Linux-fbdev-users] Basic hw operations

From: Antonio Nevado <anevado@ie...> - 2008-02-16 23:52:09

Hi all,

as a user of a fb driver I would like to write an application which 
scales an image from its original size to the screen size. To do so I'd 
like to make use of the hw acceleration capabilities of my card. At the 
moment I can mmap the hw engine getting access to the registers, but 
unfortunately I don't know the behaviour of the basic hw operations. 
I've been googling a lot but I'm not able to find the appropiate document.

I would appreciate if someone could give a hint in this sense. Does 
anyone know any good ebook or howto? What I need is a general document.

By the way, I'm using viafb from viaarena and the card is a VIA CN700.

Thanks a lot!

Antonio
