2014-05-21Use classic-equivalent DPMS codeAdam Jackson1-0/+5
The RANDR port code does... something else. It looks well-intentioned but it breaks display setup on a couple of chips so it's wrong. Probably this is just crtc dpms vs. output dpms confusion. Signed-off-by: Adam Jackson <ajax@redhat.com>

2014-03-14xf86-video-mga: fix a lockup in the mga driverMikulas Patocka1-3/+9
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 Patocka2-0/+40
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 Eich1-1/+21
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>
