Hello,
First, my system set up
Fedora 14 Before : 2.6.35.6 booted with drm.debug=0x07
I see drm:r600_irq_process, IH: CP int: 0x00000000 and No IH: CP EOP
with the default**fedora 14 install with the above mentioned kernel
After: 3.0.3 booted with drm.debug=0x07 When I recompile my kernel, I don't see any CP int: , but only CP EOP interrupts.
I have seen this behaviour across two machines one with fedora install & another with an ubuntu 10.10 (2.6.35.28 -> 3.0.3)
The code in r600.c specified plain switch based on the received case. Does this mean the case 176-178 are not executed when I recompile the kernel ? which doesn't sound right because its being shown in the previous kernel ?
Am I doing any mistake ? Any missing option in kernel configuration ? but then I shouldn't even see CP EOP.
Firmware exists in /lib/firmware/radeon
Any further pointers are appreciated. Please ask for more information. Vipin Jain
