Description Pi, Fengming 2008-03-02 18:20:09 UTC 
System Environment:
--------------------------

--Platform: 945gm
--Architecture: 32bit
--2D driver: git commit:ea7c7d088e0a3c3b7ab2bdd0475aa13379764bf4
--3D driver: Mesa master commit:0da03c0aa9ed120fe5ff781a365b503b8ed70e0c
--DRM:   git commit:fd595fa4dc6f788a8a1e1b56178e15f411706cb9
--Xserver:  git commit:4632ea22580c31d44b0786321668d9e78f02900e
--Kernel: 2.6.23
using the latest git code on my 945GM machine, I seperately tested the Xtest under NoAccel(adding Option "NoAccel" "true" in Xorg.conf),VESA,EXA environments and did a compare to show the differentiations.

Could you describe your testing method and environ?

Those x11 core protocol function tests shouldn't have difference in either case.

NoAccel test: adding Option "NoAccel" "true" in xorg.conf
VESA test: using Driver "vesa" in Device Section of xorg.conf
EXA test: using Driver "intel" in Device Section of xorg.conf

running Xtest under xts5 directory and run "tcc -e" to get the journal.

Carl, would you please take this one? thanks.
Comment 5 Carl Worth 2008-07-22 10:57:19 UTC 
I'll be glad to take a look.

I'm quite surprised like Zhenyu that there is any difference here. One
of the huge shortcoming of the xtest test suite is that it doesn't test
anything of the things that really matter for 2D performance today, (such
as Render extension requests).

So basically everything in xtest should hit identical code paths in the
X server whether using NoAccel or EXA.

But at some point soon I'll run the test suite on a 945 machine and see
if I can replicate these results at all.

Close as wontfix, since EXA has been removed from master code, and also none has interest in xtest now.
