[Dri-devel] DRI + Radeon + LCD has framerate cap

[Paul Z. <pe...@tr...>]

Hello,
   I have a Radeon 8500 LE with an LCD attached to the CRT output.
I've been compiling the DRI to test against NwN, glxgears, and bzflag.
So first of all, great work!

However, as of last week when I downloaded and compiled the DRI it appears 
that my glxgears framerate is capping at the vSync rate (70fps) and the 
hardware NwN fps is a little over half what it used to be, lighting/texture 
glitches and all.  I suspect that it's idling the CPU waiting for vSync in 
both.

I re-tested by using the latest trunk as of this morning and it's still 
capped.

It also appears that R200_NO_TCL no longer functions.  It was the only thing 
that allowed me to play NwN at all with the DRI since I prefer not to use the 
ATI binary drivers.  I haven't learned how to use what appears to be the DRI 
config file yet, but that's on my list of things to do this weekend.  In the 
source it looks like I can set TCL_mode to 0 in the config file to achieve 
the same effect that R200_NO_TCL used to give me.
Is my deduction correct about the config file?

If you want, when I get the time (read: tomorrow) I will use cvs update -D to 
binary search through the tree of the last 45 days and find when it changed.

I'm willing to dig into the code and find out what's wrong.  I design and 
implement software for a living and as my second favorite hobby.  So, while 
I'm not familiar with the code I believe I can be of more use than the usual 
"it's broken, help?" statements.

Just in case they may be useful I have logs available at:
http://treeofice.net/~pez/logs/
	XFree86.0.log (50K)
	glxinfo.log (4.1K)
I figure I'll sacrifice some outgoing bandwidth to keep from spamming the list 
with files unnecessarily.

System info;
Athlon 1800+, 512MB RAM, Radeon 8500LE, gentoo linux (ACCEPT_KEYWORDS="~x86"), 
2.4.20-gentoo-r7 with kernel module not built in kernel.  Using the DRI CVS 
kernel module.  The LCD monitor has a CRT connector and is connect to the CRT 
output.  I have a DVI to CRT convertor somewhere if testing through the DVI 
port is desired.

Note:
I used to get ~1450 out of glxgears, 36 fps out of NwN with the ugly hardware 
acceleration.  Now it's 70/19.  The cap happens with or without page flipping 
(makes sense).  The logs are without page flipping.

Thanks,
   Paul
