[ltp] Where have those 20 FPS gone?

[Ulrich Kuehn]

Hi,

I am just experimenting with the 2.6.11-rc3 kernel with the radeon
patch. So far it seems to work, so here's my contribution to the list:

+       {
+               .ident = "IBM ThinkPad T41 (2373-2GG)",
+               .matches = {
+                       DMI_MATCH(DMI_SYS_VENDOR, "IBM"),
+                       DMI_MATCH(DMI_PRODUCT_NAME, "23732GG"),
+               },
+       },
+

Interestingly, I noticed two issues with this kernel:

1) Compared to 2.6.10, I am missing about 20 FPS in glxgears
    2.6.10 :                    about 712
    2.6.11-rc3+radeon-patches : about 693

   Except the kernel the setup is identical.

2) When recompiling the kernel, maybe after a small config change,
   the kernel will hang when it is about to switch to the radeon
   fb console. After removing all the .o file in drivers/video and 
   subdirs, it works again. I have vesafb, radeonfb and DDC enabled.
   I guess there might be some issue with linking order in the  
   makefiles...
   If useful, I could provide my config.

Any ideas on how to resolve these issues?

Ulrich
