Re: G5 Video issue
Hi all, I tested Scott´s kernel image on my iMac G5 and it did indeed not solve the nouveau issues. Scott± thanks for sharing your newly built image! Regards, Jeroen Admittedly I am a kernel compilation newbie however this may not be the only issue. After changing the page size and recompiling the kernel: scott@debian-10-DG5:~$ uname -a Linux debian-10-DG5 5.6.14 #1 SMP Mon Jun 15 18:21:13 CDT 2020 ppc64 GNU/Linux scott@debian-10-DG5:~$ getconf PAGESIZE 4096 [ 23.626150] u3msi: allocated virq 0x20 (hw 0x8) addr 0xfee0 [ 23.682413] u3msi: allocated virq 0x21 (hw 0x9) addr 0xfee0 [ 25.343462] nouveau :0a:00.0: DRM: 0x14CC: Parsing digital output script table [ 25.413056] nouveau :0a:00.0: DRM: 0x14CC: Parsing digital output script table [ 26.899243] tg3 0001:05:04.1 enP1p5s4f1: Link is up at 1000 Mbps, full duplex [ 26.899248] tg3 0001:05:04.1 enP1p5s4f1: Flow control is on for TX and on for RX [ 26.899273] IPv6: ADDRCONF(NETDEV_CHANGE): enP1p5s4f1: link becomes ready [ 30.638637] fuse: init (API version 7.31) [ 2895.662905] nouveau :0a:00.0: gr: intr 0010 [ERROR] nsource 0002 [DATA_ERROR] nstatus 0200 [BAD_ARGUMENT] ch 1 [000d3000 Xorg[470]] subc 7 class 4097 mthd 0208 data 02000248 [ 2975.214714] nouveau :0a:00.0: gr: intr 0010 [ERROR] nsource 0002 [DATA_ERROR] nstatus 0200 [BAD_ARGUMENT] ch 1 [000d3000 Xorg[470]] subc 7 class 4097 mthd 0208 data 02000248 [ 2979.828455] nouveau :0a:00.0: gr: intr 0010 [ERROR] nsource 0002 [DATA_ERROR] nstatus 0200 [BAD_ARGUMENT] ch 1 [000d3000 Xorg[470]] subc 7 class 4097 mthd 0208 data 02000248 The display is still quite problematic.

Ok, having read through everything, it seems non-trivial. We should revert to 4k pages on ppc64be then. There is no reason to enable 64k pages for us. That may be well the case for ppc64el though.

G5 Video issue
I have a Power Mac G5 dual 2.3GHz with 8GB of ram model PowerMac11,2 with a Nvidia GeForce 6600. The machine is triple booted with OS X Leopard, Ubuntu 16.04.6, and Debian booting via GRUB. Video works fine under Leopard and Ubuntu but is basically unusable under Debian once the desktop is loaded. As one can see in the dmesg file there seems to be nouveau interrupt issues.
