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.

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. Most desktops today use ARGB cursors anyhow which are not supported by this driver anyhow. Thus the performance penalty should be irrelevant. Signed-off-by: Egbert Eich <eich@freedesktop.org>

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>
