fbdev: remove cyblafb driver

2009-04-01T15:59:33+00:00

A tridentfb driver has all the functionality of the cyblafb driver without
the bugs of the latter.

Changes to the tridentfb driver:

- FBINFO_READS_FAST added to the tridentfb.  The cyblafb used a blitter
  for scrolling which is faster than color expansion on Cyberblade
  chipsets.  The blitter is slower on a discrete Blade3D core.  Use the
  blitter for scrolling in the tridentfb only for integrated Blade3D
  cores.  Now, scrolling speed is about equal for the tridentfb and the
  cyblafb.

- a copyright notice addition is done on request of Jani Monoses (the
  first author of the tridentfb).

Tested on AGP Blade3D card and PCChips
M787CLR motherboard: VIA C3 cpu +
VT8601 north  bridge (aka Cyberblade/i1).

[ARM] pxafb: add support for overlay1 and overlay2 as framebuffer devices

2008-12-29T10:00:04+00:00

PXA27x and later processors support overlay1 and overlay2 on-top of the
base framebuffer (although under-neath the base is also possible). They
support palette and no-palette RGB formats, as well as YUV formats (only
available on overlay2). These overlays have dedicated DMA channels and
behave in a similar way as a framebuffer.

This heavily simplified and re-structured work is based on the original
pxafb_overlay.c (which is pending for mainline merge for a long time).

The major problems with this pxafb_overlay.c are (if you are interested
in the history):

  1. heavily redundant (the control logics for overlay1 and overlay2 are
     actually identical except for some small operations,  which are now
     abstracted into a 'pxafb_layer_ops' structure)

  2. a lot of useless and un-tested code (two workarounds which are now
     fixed on mature silicons)

  3. cursorfb is actually useless, hardware cursor should not be used
     this way, and the code was actually un-tested for a long time.

The code in this patch should be self-explanatory, I tried to add minimum
comments. As said, this is basically simplified, there are several things
still on the pending list:

  1. palette mode is un-supported and un-tested (although re-using the
     palette code of the base framebuffer is actually very easy now with
     previous clean-up patches)

  2. fb_pan_display for overlay(s) is un-supported

  3. the base framebuffer can actually be abstracted by 'pxafb_layer' as
     well, which will help further re-use of the code and keep a better
     and consistent structure. (This is the reason I named it 'pxafb_layer'
     instead of 'pxafb_overlay' or something alike)

See Documentation/fb/pxafb.txt for additional usage information.

[ARM] pxafb: allow video memory size to be configurable

2008-12-29T09:59:16+00:00

The amount of video memory size is decided according to the following
order:

1.  x  x  by default, which is the backward
   compatible way

2. size specified in platform data

3. size specified in module parameter 'options' string or specified in
   kernel boot command line (see updated Documentation/fb/pxafb.txt)

And now since the memory is allocated from system memory, the pxafb_mmap
can be removed and the default fb_mmap() should be working all right.

Also, since we now have introduced the 'struct pxafb_dma_buff' for DMA
descriptors and palettes, the allocation can be separated cleanly.

NOTE: the LCD DMA actually supports chained transfer (i.e. page-based
transfers), to simplify the logic and keep the performance (with less
TLB misses when accessing from memory mapped user space), the memory
is allocated by alloc_pages_*() to ensures it's physical contiguous.

intelfb: support 945GME (as used in ASUS Eee 901)

2008-10-16T18:21:42+00:00

Add support for Intel's 945GME graphics chip to the intelfb driver.  I
have assumed that the 945GME is identical to the already-supported 945GM
apart from its PCI IDs; this is based on a quick look at the X driver for
these chips which seems to treat them identically.

The 945GME is used in the ASUS Eee 901, and I coded this in the hope that
I'd be able to use it to get a console at the native 1024x600 resolution
which is not known to the BIOS.  I realised too late that the intelfb
driver does not support mode changing on laptops, so it won't be any
use for me.
