Just a curiosity, i've only two powerpc machines[1] equipped with PCIE videocards and both them are not able to boot with radeonkms. Modern PCI-E videocards are not recognized by the old linux framebuffer subsystem and they solely can be managed by the new KMS frame buffer that doesn't work properly on Power Architecture.
That's too broad a statement, it works fine on other PowerPC machines (PowerMacs, some embedded boards).
hi Michel, thanks a lot for your help, i really appreciate it.
If you say they were tested on real Power Architecture boards with PCIE videocards thus it is reassuring... and i'm happy that you understand my previus assertion wasn't affected by malevolence or sarcasm. Indeed i'm also a bit troubled 'n frustrated thinking that next release of mesa 'll do extend use of llvm (that doesn't work properly on linuxppc and totally untested on linuxppc64)
I don't see any reason to worry yet. LLVM is still completely optional in Mesa 8.0, and if you're worrying about the upcoming use of LLVM in the drivers for newer Radeons, I don't think the current problems in the LLVM usage of llvmpipe/draw on PPC will necessarily translate to that, as I suspect at least some of the issues are specific to the LLVM PPC backend, which won't be used in that case.
Btw, to sum up the list of Power Architecture machines with PCIE that aim to be a desktop/workstation: Apple iMac G5 (iSight), Apple PowerMac Quad G5, YDL Powerstation 2x970MP and Acube Sam460ex . And the last two, on present evidence (my attempts), aren't able to boot up if bootkernel has kms enabled.
Which radeon card, kernel log please ?
