Description Eric Hattemer 2016-02-13 03:00:58 UTC 
Description of problem:

When adding a 3rd or 4th monitor from a second card with xrandr --output ..--right-of..., Xorg.0.log throws:
"Cannot do multiple crtcs without X server dirty tracking 2 interface\n"
and errors about slave pixmap memory.

Version-Release number of selected component (if applicable):

7.6.0-0.4.20150729git5510cd6

How reproducible:

Need 4ish monitors.

Steps to Reproduce:
1. Get 2 Radeon cards with 2 ports each (I have two 5450's with 512MB each).
2. Use a blank device/screen/screenlayout/monitor setup
3. After two monitors activate, try using xrandr to activate a third and fourth

Actual results:

The third monitor activates in a sketchy mode where it doesn't work.  The fourth monitor refuses to activate.


Expected results:

Both extra monitors activate.


Additional info:

The problem is that xorg 1.17 or 1.18 replaced "HAS_DIRTYTRACKING2" with "HAS_DIRTYTRACKING_ROTATION" in pixmap.h and the old version of xf86-video-ati still looks for HAS_DIRTYTRACKING2.  The newest version of xf86-video-ati looks for either:
#if !defined(HAS_DIRTYTRACKING_ROTATION) && !defined(HAS_DIRTYTRACKING2)

I took the spec file from xorg-x11-drv-ati-7.6.0-0.4.20150729git5510cd6.fc23.src.rpm and the source from git://anongit.freedesktop.org/xorg/driver/xf86-video-ati , connected the two, got rid of the comments with %'s in them (not sure why that's a problem), and it seems to work fine now.  I'm not sure where the git5510cd6 string comes from.  The version I'm using ends in:

With 4 monitors and Xinerama off, I get like 5fps, but at least it's consistent (with 2 monitors and vsync off, I can get hundreds).  With Xinerama on and the old 7.6.0-0.4.20150729git5510cd6 driver, compiz-manager would stall out for up to a minute every other time a window was closed.  So I'd call this an improvement, sort of, but you should still do your own testing for the 1/20 version before releasing it.
