Ani and others :-)
I was hoping you could lend me some insight :-) I'm trying to do
some work with DirectFB, and I'm now running into a slight problem
concerning getting output on the VGA port.
I've e-mailed the directfb-dev mailing list about it and had some
interesting conversations, but the end result was basically: "You should
check with Ani Joshi about that, and maybe ask on the linux-fbdev-devel
mailing list".
So now I'm asking here :-) Below this I'm including the
description of the problem I'm seeing that I sent to the directfb-dev
mailing list.
Can anyone help me out? Thanks :-)

It took me a while to figure it out what I know so far, and I'm still not
100% sure what's going on...
If I run *any* DirectFB application, the screen blanks. The system
doesn't lock. I can ssh in and see the application listed in the process
table. For example, running df_fire, the screen blanks and, after a few
seconds, the monitor goes to sleep (as if it's no longer getting a
signal)... Hitting the 'esc' key brings back the vt, just as usual when
runnin the application.
Running dfbsee produces similar results. However, with any video that I
play, I can hear the audio stream :-) I just can't see anything...
Now, when I first experienced this, I posted about it on either
directfb-dev or directfb-user. A short while later, I figured out a
workaround :-)
Instead of booting with my CRT plugged into the VGA port, I used a
DVI-to-VGA adapter (that came with my Radeon 7500), and plugged the
monitor into the DVI-A port. Lo' and behold, DirectFB applications were
now showing up :-)
Since then I've done some video card swapping and now have a "Powered By
ATI" Radeon 8500 LE. This card has both a VGA port and a DVI-D port, but
no adapter. The old adapter doesn't work for this card because it's
designed for DVI-A as compared to DVI-D.
I've encountered similar problems elsewhere, too. For example, a hacked
radeon 7500 driver for BeOS would only display on the DVI port, even if
the computer booted up fine with a monitor on the VGA port.
Of course, I just don't know why this is the case :-)
I've been poking around on-line looking for a DVI-D to VGA adapter, but
very few of the shops that sell them on-line clarify if it's DVI-A or
DVI-D :-)

Hi,
In cfb_copyarea(), `tmp' must be unsigned long because it is used to store
unsigned long values (see patch at the end).
cfb_copyarea() also doesn't clear the bits to modify in the first and last
words of a line, e.g. it does
| last = (FB_READ(src) & start_mask);
|
| if (shift > 0)
| FB_WRITE(FB_READ(dst) | (last >> shift_right), dst);
^^^^^^^^^^^^
After this read, the bits to modify must be cleared first, before the OR!
I'm working on a version of cfb_copyarea() that fixes this and handles _all_
possible values of var.bits_per_pixel (the current code assumes
var.bits_per_pixel is a multiple of 8). Stay tuned!

Oops. This might fix the one bug I see sometimes. When I delete some

WHat do you mean? Functionality from a userland perspective or from inside
the kernel. Which version of the kernel are you looking at?

Well, I mend it like this:
I'm trying to build a framebuffer for an embedded ARM platform (which
doesn't use any kind of a Lunix distr).
I want to use a framebuffer, because some apps need it. For example the
ZEN browser I want to implement on this platform.
So my question is:
What basic functions does a framebuffer normally have, what is need to
initialize for these functions?
Can I see the framebuffer as the API between the video hardware and any
application what uses the video hardware?
Whit kind regards,
Vincent Ivens

You can check the linux-2.5.51 for insights. But if you just want to
implement the API without necessarily conforming to linux's framebuffer
support (don't want to use linux), then:
First you need hardware with linear video memory.
If you want compatibility with standard fb_apps , then you need the
following;
1. accessing the driver as a file (/dev/fbx) - the name is pretty much
hardwired.
2. support standard file operations (open, close, read, write). The
read/write operation accesses the video memory.
3. This is the biggie: support for most fb_specific ioctls (check
drivers/video/fbmem.c).
Required ioctl support:
a. Setting the struct fb_var_screeninfo. This is basically the
structure used to communicate between user apps and the driver, and
contains information that can modify the video/framebuffer state
depending on the capabilities of the hardware. As for the video
/framebuffer state, it encompasses the dimensions of the display, the
pixelformat, the color information, etc, as described in the file
linux/include/linux/fb.h.
You don't have to follow everything in the request. In fact, you don't
even have to do anything at all, but you must return an
fb_var_screeninfo structure that is valid for the driver. It's like the
app saying "this is what I want" and the driver returning with "this is
what you get, take it or leave it".
b. Getting the struct fb_var_screeninfo. This is simple enough, it
returns the structure containing information describing the current
state.
c. Getting struct fb_fix_screeninfo. This structure contains
information that cannot be altered by outside requests, that's why get
is only supported. It does partly depend on fb_var_screeninfo, but is
more or less hardware specific information. This is a one way ioctl,
driver to user.
As for the rest of the ioctls, you can just return success or fail.
4. have video memory mappable to user space (check fb_mmap in fbmem.c).
Although optional, practically all apps use/need this.
5. You may wish to skip console support because that entails a lot of
work. (and you probably don't need this)
> So my question is:
> What basic functions does a framebuffer normally have, what is need to
> initialize for these functions?
At a bare minimum, the driver must set the hardware into a state as
imposed by itself during initialization, or by requests through
fb_var_screeninfo..
For most apps, mmap support must be included.
The simplest driver then would support #1, #2, #4, and set the video
mode at initialization. As for #3, just return success/fail, making
sure the driver channels back the correct information to the userland
app, without actually doing anything at all.
> Can I see the framebuffer as the API between the video hardware and any
> application what uses the video hardware?
>
Yes, that's the goal of the framebuffer, to abstract the underlying
hardware into a well-defined interface. But to keep it as simple and as
cross-platform as possible, the API is at the barest minimum (set the
hardware, set the mode, and offer access to the graphics memory either
through file reads/writes or mmap). The rest are icing on the cake.
If I missed anything, feel free.

Hi,
I have a problem when I change the bpp value, here is the code:
if( ioctl(fbd, FBIOGET_VSCREENINFO, &var_info) == -1){
perror("\nError IOCTL 1");
exit(0);
}
printf("\n bpp: %d", var_info.bits_per_pixel); // output is bpp: 16
var_info.bits_per_pixel = 24;
if( ioctl(fbd, FBIOPUT_VSCREENINFO, &var_info) == -1){
perror("\nError IOCTL 2");
exit(0);
}
The program exit with the following message error:
Error IOCTL 2: Invalid argument
How can I set the bpp value? Should I modify the file /etc/X11/XF86Config?
I have another problem, I try to write a simple program that reads frame from framebuffer and then creates a Divx file of a few seconds.
I map the framebuffer to a buffer, but the program crash with a segmentation fault:
screen_buffer = (char *)malloc(DIM_BUFFER * sizeof(char));
screen_buffer = (void *)mmap(0, DIM_BUFFER, PROT_READ, MAP_SHARED, fbd, 0);
encFrame.image = (void *)screen_buffer; <--- causes seg fault
What's wrong?
Thanks,
Paolo Gilardetti

This will depend on the driver you are using. vesafb does not support
any change to fb_var_screeninfo. Other drivers, may not round off
invalid values: ie bpp == 24 is not supported. Also, increasing bpp
implies that more video memory will be required if var.xres_virtual and
var.yres_virtual remains the same. So try to check xres, yres,
xres_virtual and yres_virtual against fix.smem_len and
var.bits_per_pixel.
fix.smem_len >= (var.bits_per_pixel * var.xres_virtual)/8 *
var.yres_virtual.
/etc/X11/XF86Config has nothing to with fbdev.

you don't need this step.

check if mmap failed, (returns -1).

memcpy(encFrame.image, screen_bufer, DIM_BUFFER) is a more appropriate
step to get the contents.

When I start the system with YWRAP activated I have scrolling problems ,
in fact when I make the screen scrolling for a while (for example during
the examination of a document with "less" or during the compilation of a
software) , on the screen starts appear colored lines on the screen and
these starts scrolling . When the screen is full of this lines these
disappear and the text is back , but after few scroll again these lines
appears. With 2.4.21-ac4 kernel the problem is more evident than the
2.4.21 "vanilla" . If I reboot the system doesn't appears lines
anymore, but instead of the lines appears words of the precedent boot of
the system, seems like that the video memory have not been reset , and
that the FB takes parts of the Video data Junk remained after the reboot
and visualize these on the screen. Seems like an error in addressing the
video memory .
With 2.4.20 and precedent this doesn't happen .
Please help me :cry:

Hello !
I have written a driver for 69030 card and was able to program the BitBLT engine .
Now I want to play MPEG4 video on the card.I will get input as RGB not the YUV data initially.
I need a very high frame rate of around 25-30fps. What part of hardware I need to program additionally other than BitBLT engine and how to achieve this rate? Will the way of using fbmem into pages help inthis regard? Will utilisation of double buffering helpin this regard???
Thanking u in advance

how can i put the boot message onto the framebuffer_lcd? can uclinux 2.4
do this ?
I have write a framebuffer driver base on vfb.c , and it is
ok to use(I wrote a program to test.my lcd is 16 color,320x240, i alloc 37kB
for the screen memory.i use write(fd,buff,count) function ,and the screen's
color is changed.).Now, i want the screen to display english or chinese and
picture, how to do , and have uclinux2.4 done this for me ? the only things
for me is to find it and connect? i am puzzled , please help me.
thans a lot.

1. If you are developing your own driver, you will need the following hooks.
(You may not need all of them if you don't plan on changing video modes after
initialization. Or at least provide a stub).
static struct fb_ops xxxfb_ops = {
owner: THIS_MODULE,
fb_get_fix: xxxfb_get_fix,
fb_get_var: xxxfb_get_var,
fb_set_var: xxxfb_set_var,
fb_get_cmap: xxxfb_get_cmap,
fb_set_cmap: xxxfb_set_cmap,
fb_pan_display: xxxfb_pan_display,
};
Then in your init, something like this:
info->fb_ops = &xxxfb_ops;
2. Add this to fbmem.c, (in static struct fb_drivers[]):
#ifdef CONFIG_FB_PVR2
{ "xxx", xxxfb_init, xxxfb_setup },
#endif
xxxfb_setup can be NULL.
3. If you can use one of the generic drawing functions, (see any of the
fbcon_cfb*.c files). If not, you have to create those too.

hi.
i have this problem.
kernel 2.6.16.2
intelfb: Framebuffer driver for Intel(R)
830M/845G/852GM/855GM/865G/915G/915GM chipsets
intelfb: Version 0.9.2
intelfb: 00:02.0: Intel(R) 855GME, aperture size 128MB, stolen memory 892kB
intelfb: Non-CRT device is enabled ( LVDS port ). Disabling mode switching.
intelfb: Video mode must be programmed at boot time.
the driver (*) is inside kernel.
Thanks

So where is the problem?

Yes - of course, why not? It should be possible to compile a framebuffer
driver into the kernel without problems, and it should be possible to
load it as a module ... even from within xterm ;-)
Why do you believe that this is related to any of the problems?

From: Krzysztof Helt <krzysztof.h1@wp.pl>
This patch fixes over 850 errors and warnings pointed
out by the checkpatch.pl script.
Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl>
---
I run the checkpatch.pl script on the whole drivers/video
directory. The most errors are in drivers which share code
with X11 (sis, nvidia). The cirrus driver had the most errors
as a non-X11 driver.

From: Krzysztof Helt <krzysztof.h1@wp.pl>
This patch fixes over 850 errors and warnings pointed
out by the checkpatch.pl script.
Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl>
---
I run the checkpatch.pl script on the whole drivers/video
directory. The most errors are in drivers which share code
with X11 (sis, nvidia). The cirrus driver had the most errors
as a non-X11 driver.
