--- Comment #10 from Connor Behan <[email protected]> --- I managed to get r128-support working with the current X server (RAC removal, pciTag removal, new vgahw API and new screen API). In this driver, the line http://cgit.freedesktop.org/~agd5f/xf86-video-ati/tree/src/radeon_output.c?h=r128-support#n272 succeeds. I have checked the bits and it is OUTREG(0x0060, INREG(0x0060) & ~0x3). However, if I try this in the r128 driver (my failed attempt patch), the exact same call causes a crash. I need to figure out this part first: how can a call to OUTREG() crash the X server? I have checked and info->PciInfo, info->MMIOAddr and info->MMIOSize are the same in both cases. Even if I figure this out, it will not be enough for a DDC detection. When I run r128-support, there is no crash, but xf86DoEDID_DDC2() tells me that the VGA monitor is not plugged in even when it is. -- You are receiving this mail because: You are on the CC list for the bug.
