gxt4500: use display information in info not in var for panning

2011-08-19T08:31:17+00:00

We must not use any information in the passed var besides xoffset,
yoffset and vmode as otherwise applications might abuse it.

pci: use pci_ioremap_bar() in drivers/video

2009-01-06T23:59:26+00:00

Use the newly introduced pci_ioremap_bar() function in drivers/video.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.

fbdev: use DIV_ROUND_UP or roundup

2008-04-28T15:58:35+00:00

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /
(d)) but is perhaps more readable.

An extract of the semantic patch that makes this change is as follows:

[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).

[PATCH] Fbdev driver for IBM GXT4500P videocards

2006-12-10T17:57:20+00:00

This is an fbdev driver for the IBM GXT4500P display card found in some IBM
System P (pSeries) machines.  These cards have hardware 2D and 3D
capabilities, but the driver does not use them; it just exports a dumb
framebuffer.
