hi guyz, first my kudos this driveris geeting great and fast (at least for my needs) but im having a weird pm issue wich i like to report, so i need your help to enlight me about how to debug it.
my specs
phenom II X4 955 BE @ 4ghz
AMD Radeon HD 4850x2
1 32" HDTV connected through DVI-1
1 22" Monitor connected through DVI-0
OS Kubuntu 10.04.1 + ppa motu:xorgedgers
kernel 2.6.36-rc4 from ubuntu kernel team
PM settings dynpm/profile low(aka tested with both)
ok here is the issues i discover in my pc running r600 driver(i know pm is almost KMS exclusive, r600 is just to make it clearer to read) that when i have only 1 monitor output active the driver with almost any flicker anymore keep a decent temperature close to fglrx(this is normal desktop composite + chromium hardware accelerated) but when i activate the second monitor output in clone or extended mode the gpu goes to maximun settings(aka high and 75?) whatever the option i pass to the pm system
when i disable the second monitor output the pm system goes back to normal.
Notes:
1.) 4850x2 card have 4 DVI outputs aka 2 per GPU, im using the DVI0 and DVI1 which are dependant on GPU0
2.) is amazing but KMS recognize my second GPU(GPU1) and apply PM and keep it COOL , btw when i trigger the bug only GPU0 is affected GPU1 keeps low temps no matter what happens with GPU0
3 i heard that pm code in KMS shut down many PCI-e lanes depending the configuration, now since X2 cards are a crossfire system but pasted in a single PCB, is possible that when i set GPU1 to profile:low it kills many pci-e lanes no matter that GPU0 is on dynpm or profile:high, since the pci-e port is the same?
----------is kms aware of this kind of setup?
----------i can help to debug or provide test info, if you send me some instruction of what to look at
4 since KMS recongnize and provide acceleration for both of my GPU's(im impressed btw), it means some work has been done in the multiGPU arena? (mmm in fact xorg logs show me that my second GPU is getting DRI accel too and it works but not in parallel yet)
