2009-06-16intelfb: fix a bug when changing video timingPaul Menzel
When changing video timing dynamically via fbset the screen sporadically is rendered black. With the attached fix which disables VCO prior to timing register change the problem disappears. I had a look at the Xserver register setup code. Here the VCO is disabled in the same way [1]. This patch is taken from vga-sync-field version 0.0.11 [2][3].

2008-10-16intelfb: support 945GME (as used in ASUS Eee 901)Phil Endecott
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.

2008-04-28fbdev: intelfb: add support for the Intel Integrated Graphics Controller ↵Maik Broemme
965G/965GM Add support for the 965G and 965GM graphic chipsets to the intelfb driver. I have a notebook with an Intel Mobile GM965/GL960 Integrated Graphics Controller and with the attached patch the framebuffer comes up. I have tested it a bit with DirectFB to make sure it is working stable. I also have an Intel Mobile GM945 and I compared the results, the programming interface of the 9xx series from Intel is mostly the same, so I think the patch should add all the functionality which the 945GM has.

A generalized vsync accounting struct is defined, with the intent that it can encapsulate per-pipe vsync related info in the future. Currently a single instance is hard-coded. The interrupt service routine currently only looks for vsync interrupts on pipe A, and increments a counter and wakes up anyone waiting on it.

2005-11-07[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

2005-05-28[PATCH] intelfb section fixPatrick McManus
On Nov 16 2004 a change to intelfbdrv.c was commited (as part of 0.9.2 it looks like) that added __initdata to all of the module param variables that seems to create the opportunity for an oops. I've recently been chasing an OOPS (http://marc.theaimsgroup.com/?l=linux-kernel&m=111552250920370&w=2) I created by reading every file on the /sys file system and I've traced it back to this code in the intelfbdrv. Though I had root privs in my initial problem report, it turns out they are un-necessary to generate the oops - all you've got to do is "cat /sys/module/intelfb/parameters/mode" enough times and eventually it will oops. This is because sysfs automatically exports all module_param declarations to the sysfs file system.. which means those variables can be dynamically evaluated at any later time, which of course means marking them __initdata is a bad idea ;).. when they happen to be char *'s it is an especially bad idea ;). Applying the patch below clears up the OOPS for me.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
