[off-list ref] (04/01/08 1.1406)
   [IMSTT FBDEV] No longer need these special macros.

[off-list ref] (04/01/08 1.1404)
   [NEOMAGIC FBDEV] Fixed the nasty bug causing a oops. I needed to call neofb_check_var at bootup to fix the yres_virtual value. Updated the still not functional cursor code. The hardware imageblit code has a problem.

<jsimmons@debian.(none)> (04/01/07 1.1402)
   [MACH 64] Hardware info from the specs.

<jsimmons@debian.(none)> (04/01/07 1.1400)
   [VT CONSOLE] Pavel patch to fix the trailing cursor bug. The fix is to first hide the cursor _then_ hide the software cursor. A very old bug never discovered until now.

[off-list ref] (04/01/06 1.1398)
   [FBCON] Needed fix for resizing. Cols and rows where reversed.

[off-list ref] (04/01/06 1.1397)
   [ATY FBDEV] More PCI ids for more Mach 64 cards out there.

   [MACH64 FBDEV] Latest LCD support code.

<jsimmons@debian.(none)> (03/10/30 1.1354)

[off-list ref] (03/10/14 1.1337.25.12)
   [FBDEV] Moved kernel header files to be visible only when compiling for the kernel. Userland doesn't need these header files. It also makes shifting from kernel version to kernel version easier.

[off-list ref] (03/09/18 1.1267.1.19)
   Update sisfb driver:

   - port driver to the new framebuffer_{alloc,release} API

[off-list ref] (03/09/17 1.1267.1.18)
   Update sparc framebuffer drivers to the new API.

[off-list ref] (03/09/17 1.1267.40.1)
   Add new API framebuffer_alloc and framebuffer_release.
   
   Framebuffer info structure (ie. struct fb_info) must be obtained from
   framebuffer_alloc. When it is no longer needed (after unregister_framebuffer
   and clean up) it can be released using framebuffer_release.
   
   If the framebuffer is not registered yet (eg. on error path) then fb_info must
   be released via kfree.

Here are the changes.

   [PVR2 FBDEV] Port of the Dreamcast Frambuffer to the new api.

Please drop this from your patch, it re-introduces a number of parse
errors that I already fixed in the 2.6 tree.

On another note, I do have some more pvr2fb updates pending, but I'll send
these to you seperately.

Try it again. I missed a patch for the radeon.

[off-list ref] (03/09/17 1.1267.40.1)
   Add new API framebuffer_alloc and framebuffer_release.
   
   Framebuffer info structure (ie. struct fb_info) must be obtained from
   framebuffer_alloc. When it is no longer needed (after unregister_framebuffer
   and clean up) it can be released using framebuffer_release.
   
   If the framebuffer is not registered yet (eg. on error path) then fb_info must
   be released via kfree. 

Are we sure that we want this for 2.6? Greg KH has a much less intrusive
patch, maybe you should take that instead and keep my work 2.7.

If you decide to go with framebuffer_alloc then I have more patches for
you ;)

I have been using it for awhile on various cards.

Hi, I've tested this patch (after the radeon patch update), and it's working
almost perfect with just one problem: going back from X the framebuffer
screen is completely distorted, but it can be corrected changing the depth
with fbset (-depth 8/16/32 and back to the working depth).
I have a radeon 9600 (or RV350 AP) and of course the -current- 2.6.x
driver doesn't include this PCI_ID in the code, so it "shouldn't work", but
I've added (from 2.4) the PCI_ID and some code to recognize/setup the
rv350 and the current 2.6.x driver -just- worked, I cannot use fbset to
set resolutions/depths, because it screws up the whole framebuffer. But
going back from X and to X works ok if I don't touch the framebuffer with
fbset. This is with my modified verison of the 2.6.x old driver.
IIRC there was a mail about the binary driver from ATI touching something
hidden in the chip and that I think may be the cause of this "distortion" when
switching from and to X (yes, sometimes X screws up when switching from
framebuffer, but running any GL app corrects everything in X, ej: glxgears).
So the strange thing about this is the old driver working "almost" correctly
with the binary X drivers from ATI and the new driver working flawless in 
console but destroying completely the state of the card when switching
to/from X (and of course X using binary ATI drivers).

Salu2.
Javier Villavicencio.

We need to add a callback to the fbdev when restoring the console
from KD_GRAPHICS to KD_TEXT, maybe a special case of "switch".

James, I suggest turning that into a set_par call with a flag for
'forcing' the mode to be re-applied fully even if it already matches
the HW. (Currently, set_par in some drivers like my new radeonfb,
for obvious perfs reasons, will not touch the HW if the var and the
par are matching already).

Ben.
