2015-07-01MGA DDX: make it possible to find EXA supportMatthew Rezny
Newer versions of the xserver stricter requirements on header order which caused the configure tests for EXA support to erroneously fail. Since XAA was already removed from an earlier version of xserver, the configure failure meant no acceleration was possible. Patch configure tests similar to r128.

2014-03-14xf86-video-mga: fix a lockup in the mga driverMikulas Patocka
I've had a Xserver lockup in the mga driver, examining it with gdb showed this obviously broken loop: count = INREG(MGAREG_VCOUNT) + 2; while(INREG(MGAREG_VCOUNT) < count); It reads the line counter and waits until the counter advances by two. The cause of the lockup is this - if the kernel reschedules the Xorg process and lets it run in such a moment when INREG(MGAREG_VCOUNT) returns the maximum (or maximum minus 1) line count, the loop never exits.

2014-03-14xf86-video-mga: set the pan_ctl registerMikulas Patocka
On my Matrox G550 most videomodes in Xorg didn't work. I found out that it works if Xorg pixel clock is similar to the pixel clock set on framebuffer console. Further analysis showed that the Linux framebuffer driver sets the pan_ctl register (the register 0xa2) according to the pixel clock, the Xorg driver doesn't set it. I copied the code to set the pan_ctl register from the Linux kernel to the Xorg driver, and most videomodes in Xorg work. The pan_ctl register is required for both analog and digital output. The pan_ctl register is saved and restored, this is required so that we restore text-mode screen or Linux framebuffer correctly. Signed-off-by: Dave Airlie <airlied@redhat.com>

2013-10-25Disable HW cursor by default on G200 server chipsEgbert Eich
Disable HW cursor by default on G200 server chips as these chips a re often used with a remote graphics link which cannot display the HW cursor. This can be overridden by a config option.

2011-09-20Delete support for MGA's proprietary HAL: unifdef USEMGAHAL.Jamey Sharp
This patch produced with: for f in `git grep -Fwl USEMGAHAL`; do unifdef -B -UUSEMGAHAL $f | sponge $f done Adam Jackson wrote: Hey, so, remember back in the dark ages when dualhead was this insanely wild differentiating feature? Matrox thought it was so special, in fact, that they hid most of the implementation of it (and a bunch of other stuff) in a binary-only blob called the HALlib. As you'd expect it was pretty much a cut-and-paste of the relevant Windows code, and then some open glue to keep it working; clientlx.c is that glue. I guess the theory was that if you don't tell people which registers to duplicate to implement a second pipe in their own hardware, they won't figure it out? A pretty eyeroll-worthy idea even at the time, and definitely not something we should be condoning anymore. Kill it with fire, but while you're at it, untangle the hideous mess of MGA_HAL() macros too. Signed-off-by: Jamey Sharp <jamey@minilop.net> Cc: Adam Jackson <ajax@redhat.com>
