[PATCH] stifb: detect cards in double buffer mode more reliably

2007-08-25T15:24:20+00:00

Visualize-EG, Graffiti and A4450A graphics cards on PARISC can
be configured in double-buffer and standard mode, but the stifb
driver supports standard mode only.
This patch detects double-buffered cards more reliable.

It is a real bugfix for a very nasty problem for all parisc users which have
wrongly configured their graphic card.  The problem: The stifb graphics driver
will not detect that the card is wrongly configured and then nevertheless just
enables the graphics mode, which it shouldn't.  In the end, the user will see
no further updates / boot messages on the screen.

We had documented this problem already on our FAQ
(http://parisc-linux.org/faq/index.html#viseg "Why do I get corrupted graphics
with my Vis-EG/Graffiti/A4450A card?") but people still run into this problem.
 So having this fix in as early as possible can help us.

VIDEO: Fix FFB DAC revision probing

2007-04-06T10:43:13+00:00

[VIDEO] ffb: Fix two DAC handling bugs.

The determination of whether the DAC has inverted cursor logic is
broken, import the version checks the X.org driver uses to fix this.

Next, when we change the timing generator, borrow code from X.org that
does 10 NOP reads of the timing generator register afterwards to make
sure the video-enable transition occurs cleanly.

Finally, use macros for the DAC registers and fields in order to
provide documentation for the next person who reads this code.

video/aty/mach64_ct.c: fix bogus delay loop

2007-03-09T18:50:31+00:00

CT based mach64 cards were reported to hang on sparc64 boxes when
compiled with gcc-4.1.x and later.

Looking at this piece of code, it's no surprise.  A critical
delay was implemented as an empty for() loop, and gcc 4.0.x
and previous did not optimize it away, so we did get a delay.

But gcc-4.1.x and later can optimize it away, and we get crashes.

Use a real udelay() to fix this.  Fix verified on SunBlade100.

[SPARC64]: Fix of_iounmap() region release.

2006-12-31T22:06:05+00:00

We need to pass in the resource otherwise we cannot
release the region properly.  We must know whether it is
an I/O or MEM resource.

[PATCH] gxt4500: Fix colormap and PLL setting, support GXT6000P

2006-12-22T16:55:50+00:00

This fixes some bugs in the gxt4500 framebuffer driver, and adds support
for GXT6000P cards.

First, I had the red and blue channels swapped in the colormap update code,
resulting in penguins' noses and feet turning blue (though the penguins
weren't actually shivering :).

Secondly, the code that calculated the values to put in the PLL that
generates the pixel clock wasn't observing some constraints that I wasn't
originally aware of, but am now that I have some documentation on the chip.

The GXT6000P is essentially identical from software's point of view, except
for a different reference clock for the PLL, and the addition of a geometry
engine (which this driver doesn't use).
