Status of radeonfb in 2.5?

Status of radeonfb in 2.5?

[Nicholas Wourms]

Hi,

I was curious to know if the maintainer for the radeonfb 
driver was planning to update it wrt James' recent API 
changes.  Considiering it is the latest line available, I'd 
hope that its brokeness will not be permanent ;-).

Cheers,
Nicholas

radeonfb for 2.5 will be updated in the next release (or 2).

Excellent!  Two other questions (not necessarily related):

A) Is it (or will it ever be) possible to run dual head 
using two different cards (like radeon & riva-tnt2)?  I know 
there is still much work to be done, but I was curious if 
this was even remotely possible.  Sorta hate to let a good 
video card go to waste if you know what I mean :-).

B) Does anyone have a painless, yet precise way of 
generating modelines for fb.modes if you are using 
XFree-4.2?  I only ask because the XFree modelines are all 
determined by i2c DDC probing, thus there are none in the 
XF86Config file.  The modeline output captured in the log 
XFree.0.log is not the same output which modeline2fb 
expects.  Anyhow, I've tried using some of the information 
in the log, but I always get funky results.  I may be 
looking in the wrong place, but the documentation for both 
the fbdev kernel drivers and the X drivers are sorely out of 
date, so please excuse me if this is a question that has 
previously been answered.  I just need some formulae to 
convert values between what shows up in XFree.0.log when i2c 
DDC probes for the modelines and what needs to go in 
fb.modes.  Thanks in advance!

Cheers,
Nicholas

I've ported radeonfb 0.1.6 to 2.5.42 (available in the linuxppc-2.5
bk tree) and will port it to James latest changes. Ani (the
maintainer) will probably then just use that port.

I think it should theoretically work, but as always the only way to tell
is to try it. :)

If the X driver supports Option "UseFBDev", you should be able to use
fbset with that.

Well there isn't much on multiheading in the documentation, so I was hoping 
for some hints or key insights into how to set this up.  Is there any 
special magic that the matrox people use to thell the kernel to initialize 
both framebuffers?

Huh?  The problem is that fbset will not work because I need to populate 
fb.modes with proper mode lines.  So at the moment fbset won't work at all.  
What I was asking, since the documention was written when XFree 3.x was 
still in use,  was how do I get (calculate) the modelines for fb.modes 
based on the information the i2c DDC probing XFree-4.2.1 outputs in 
XFree.0.log?  Or is there a better way?  What might be cool is if the fb 
drivers used the lm-sensors(i2c) capabilities to automagically probe the 
information and set up the most optimal settings.  Maybe I'm talking too 
much about something I'm not all that familiar with...  Still, it would be 
nice =).

Cheers,
Nicholas

Something like video=radeonfb video=riva ?

I was thinking of running X with Option "UseFBDev" and getting
information about the modes with fbset.

Hmm...  I guess that setting doesn't do what I thought it did.  I'll give it 
a shot and see if it works.  Thanks!

Not necessarily painless...

Given timings in X modeline format (you can generate with xvidtune):

"XRESxYRES"     MHZ   XACTIVE FP_X HSYNC BP_X    YACTIVE  FP_Y  VSYNC 
BP_Y +hsync +vsync

Then timings in fb.mode:

mode "XRESxYRES MHZ"
    # D: "MHZ, H: HorizSync kHz, V: VertRefresh Hz
    geometry xres yres vxres vyres bpp
    timings pixclock left right upper lower hsync vsync
    hsync high
    vsync high
endmode

where:

pixclock = 1000000/MHZ
left = BP_X - HSYNC
right = FP_X - XACTIVE
upper = BP_Y - VSYNC
lower = FP_Y - YACTIVE
hsync = HSYNC - FP_X
vsync = VSYNC - FP_Y

What you need to concentrate on is the timings field of fb.modes. This
also assumes that the driver actually reads the timings field.  Some
drivers disregard those values (considers only xres and yres) then
configure their own timings.

Tony,

Thank you, this is *exactly* what I was looking for!  I never knew what 
xvidtune was really for, but this sure answers that one.

It is just a matter of reformatting.  Eg, from this box:


(II) Reloading /usr/X11R6/lib/modules/libddc.a
[etc]
(II) RADEON(0): Supported Future Video Modes:
(II) RADEON(0): #0: hsize: 1600  vsize 1200  refresh: 60  vid: 16553
(II) RADEON(0): Supported additional Video Mode:
(II) RADEON(0): clock: 162.0 MHz   Image Size:  305 x 228 mm
(II) RADEON(0): h_active: 1600  h_sync: 1664  h_sync_end 1856 h_blank_end 2160 h_border: 0
(II) RADEON(0): v_active: 1200  v_sync: 1201  v_sync_end 1204 v_blanking: 1250 v_border: 0

Those lines give the data for a modeline.  That translates to:

Modeline "1600x1200x60"  162.0  1600 1664 1856 2160  1200 1201 1204 1250

Well that depends on if it is possible to initialize the card fully 
without using the graphics BIOS. To my current knowledge the Matrox card 
can do this and it is possible for the 3Dfx family of cards. This I have 
seen in the docs. As for NVIDIA cards they don't release that info and ATI 
is also funny about release such info as well :-(

Ah DDC support. I really wanted to add that into the fbdev layer but 
unfortunely I don't have the time to do that :-( Only if I did fbdev for a 
living.
