2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen1-539/+0
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.

2009-12-16matroxfb: fix problems with display stabilityAlan Cox1-1/+2
Regression caused in 2.6.23 and then despite repeated requests never fixed or dealt with (Petr promised to sort it in 2008 but seems to have forgotten). Enough is enough - remove the problem line that was added. If it upsets someone they've had two years to deal with it and at the very least it'll rattle their cage and wake them up.

With multihead support always enabled, these macros are no longer needed and make the code harder to read.

2007-08-11matroxfb: rectify jitter (G450/G550)Paul A. Clarke1-10/+13
This builds upon my previous attempts to resolve some jitter problems seen with the Matrox G450 and G550 -based cards, including odd disparities observed between x86 and Power -based machines in a somewhat less hackish way (removing the hacked ifdefs). Apparently, preference should be given to use the DVI PLL when frequencies permit, the Standard PLL otherwise. The max pixel clock for the panellink interface is extracted from the PInS information on the card and used as a limit to determine which PLL to use. Signed-off-by: Paul A.

2006-08-27[PATCH] matroxfb: fix jittery display on non-ppc systemsPaul A. Clarke1-0/+8
I wish I was happier about this patch. It'll serve as a placeholder for the moment. I'm still trying to get a G550 working in order to even reproduce the problem this patch introduces. I find that the G450 has jitter even without this patch, so it won't show me what the patch changed. At this point, I'll continue trying to get the G550 to work, and in parallel work with the G450 to work out the kinks. The patch is below. Set XDVICLKCTRL only on PPC, as doing this apparently introduces jitter on the G550, at least on x86 architectures. Signed-off-by: Paul A.

2006-05-21[PATCH] matroxfb: fix DVI setup to be more compatiblePaul A. Clarke1-2/+21
There has been a longstanding problem with the Matrox G450 and perhaps other similar cards, with modes "above" 1280x1024-60 on ppc/ppc64 boxes running Linux. Higher resolutions and/or higher refresh rates resulted in a very noticably "jittery" display, and sometimes no display, depending on the physical monitor. This patch fixes that problem on the systems I have easy access to... I've tested with SLES9SP3 (2.6.5+ kernel) and 2.6.16-rc6 custom kernels on an IBM eServer p5 520 w/G450 (a.k.a GXT135P on IBM's ppc64 systems), and a colleague of mine (Ian Romanick) tested it successfully on an Apple ppc32 box (w/GXT135P). I also tested it on IA32 box I have with a GXT135P to verify that it didn't obviously break anything. In my testing, I covered single-card, single and dual-head setups using both HD15 and DVI-D signals, on both the IA32 and ppc64 boxes. While everything appeared fine on both boxes, I did encounter one problem: I can't get any signal on the DVI-D output on the ppc64 box. However, this is also the case without my patch. I just noticed that screen-blanking only occurs on the primary display as well. Signed-off-by: Paul A.

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!
