The VGA register dumping code was leaving ARX in data mode rather than index
mode, which could cause problems for later software accessing AR* registers.
Fix it to make sure it's in index mode when we're done.
Fixes#14434.
Use PRIx32 for printing CARD32 types, and PRIx64 for portably printing uint64_t
types. Requires the addition of a new include, inttypes.h, to work. Hope C99
is ok with everybody...
LVDS mode changes how the PLL works in fairly dramatic ways; the debug code
wasn't properly accounting for those differences resulting in fairly bogus
debug output.
Be sure to check G33 chip type in:
- sdvo output
- Y-major tile
- crt detect
- and xaa composite
Sorry for that I should have fixed them very earlier...
- Use the existing single/dual-channel state when available, as changing it
doesn't appear to work out.
- Set the power state of the CLKB and B0-B3 pairs according to whether
choose to go dual-channel or not.
- Restore the LVDS register at the appropriate point (before DPLLs are
re-programmed.
This gets correct clocks detected on most harware. The SSC is always assumed
to be 66Mhz, which may not be true, but we'll fix that when we find example
hardware.
This includes not reporting some fields on hardware where those bits are
reserved, correcting one of the hardware error bit numbers, and reducing
the severity of the debugging output warnings.
Autodetect libdrm version, disable new memory manager on older libraries.
Move new M_T_ defines from i830.h to i830_xf86Crtc.h. Add many system
headers to define functions. Use i830PipeSetBase at end of mode setting
code to set DSP*BASE and flush changes. Don't duplicate PipeSetBase call
from screen init function. Make initial RandR configuration code usable on
older versions of extension so the server doesn't start in a panning mode.
Use xfree instead of free in i830_tv.c.
Add lots of register debugging to track delta from BIOS settings.
Fix various mode settings to mirror BIOS sDVO values.
Disable analog/lvds output on pipe with sDVO.
Borrow Dave Airlie's I830xf86ValidateDDCModes code.
Fix various sDVO I2C messages to mirror Dave's code.
