Hi, [workaround patch for hang-on-exit on Geode hardware in xc/programs/Xserver/hw/xfree86/drivers/nsc/gfx/vga_gu1.c] > Well, that's fine, but my suggestion is only a workaround. I don't have docs > for this chip, but it would be better to know what CRTC 0x33 is, what this code > is waiting for (0x80 isn't my idea of descriptive), and why the hardware isn't > turning off this bit. [del] After a bit of googling, I've found the offical docs on the AMD website: http://www.amd.com/us-en/ConnectivitySolutions/TechnicalResources/0,,50_2334_2496_9919,00.html You'll need a registration, but that's it. There's an AMD Geode SC1200/1201 Processor Data Book with full description of the video registers. Now, if I'd only would understand why the code is poking around in reserved registers - but probably I just don't understand what's going on there or the video registers are mapped into another region.
