it's really more output related.

|
while crtc timing and pll seem to work fine, output setup
and routing don't seem to work too reliably with atom.
AMD claims ATOM was still pretty new with r4xx so
it's probably better to stick with direct programming for
some things.
|
|
This avoids hangs that occur when touching these registers while the card is
busy with some cards.

This reverts commit 0241cac643fa1c08a45ea44f5c670b290e760ad8.
Taking the DRI lock in paths called from the SIGIO handler isn't safe. For
example, the SIGIO handler may be called while the lock is held by an AIGLX
context, resulting in deadlock. See e.g.
https://bugs.freedesktop.org/show_bug.cgi?id=13005 .

- add r3xx/r4xx MC access macros and functions
|
|
|
|
ATOM builds, but it's not hooked up yet.

Bug #12984.
|
|
These bits don't seem to be reliable or routed right
in all cases.
|
|
|
|
- Reduce the number of times we do DDC and don't
skip the magical GPIO dance when doing DDC.
- If no DDC modes are found, add the screen modes
|
|
|
|
when radeon_crtc_mode_set() is called during ScreenInit(),
we don't have pScrn->pScreen yet.
|
|
Shouldn't be needed any longer as I've finally sorted out
the LVDS issues due to the crtc setup.
|
|
For panels, both the mode and crtc values need to be updated based
on the native mode timing. This shoudl fix any remaining problems
with RMX.
|
|
|
|
allow the user to set any tv standard rather than
limiting it to what the bios says is supported.
|
|
RMX should work again with native timings after the previous
patch.
|
|
At some point we changed how hsync_wid and vsync_wid were clipped.
Previously we used the field size as a mask when building the
register. This got changed to setting the value to the field
size if it was greater. this probably explains number stange
mode bugs.

* Detect all PowerBooks with dual link DVI (according to developer.apple.com)
and both Mac Mini G4 models. Other PowerBooks and iBooks should be covered
by the 'detected as' line in /proc/cpuinfo.
* Give specific instructions for overriding and reporting incorrect detection.
* Only perform detection when Option "MacModel" isn't present with a valid
value.
* Close /proc/cpuinfo file handle when done with it.
* Coding style cleanups.

This should at least get something on the screen.
XPRESS chips, I'm looking in your general direction...
|
|
|

|
by toggling the appropriate bios scratch regs you can tell
the bios not the touch the hw while the driver is active.
This should prevent the bios from scrambling the hardware
when users open the lid or toggle bios hotkeys.

I'm not sure how reliable this is. The lid closed
bit only seems to be set if the lid is closed at boot
so LVDS will default to on if you restart X with the
lid closed after boot.
|
|
Seems XPRESS desktop chips with DVI-D list a proprietary
connector type rather than DVI-D. try and do the right thing.
Also, XPRESS chips seem to include connector type 8 and ddc
type 8 which are unknown at this time.

Include the mode restore bugfix from monolithic Xorg, that is derived
from the version in xsrc which in turn was provided by Matthieu Herb
over 3 years ago on the XFree86 lists. Suggested by various
developers, hold-back due to the working state in xorg-server 1.1.1.
Tracing down the exact change showed that the changed default color
depth made this issue a lot more prominent again. Discussed with Eric
Anholt.

fixes bug 12733

|
|
|
Seems some laptops need the native mode from the bios for
LVDS while others seem to prefer a CVT mode. Add an option
to pick the preferred mode. The default it to use the bios
table timing.

thanks to arekm on xorg-devel for testing/feedback

RS482_5975 is actually RS485. see bug 12048

Surprisingly easy, thanks to George's pci-rework changes.
