Hello,
now finally, but without time to instruct newcomers. I only post this _early_ to prove I'm not talking about hot air / vapoware. At the moment - when building with gcc - I get an assertiob error and resulting panic _also_ on Sol11.1++ (unlike 2 weeks ago when mostly building with the redistributable osol Studio12.1). However, I attach the old module bins from two weeks ago. I said I won't instruct end-users, this means I won't mention that you first need a worjing agpgart and also not (beyond this short note), that on Illumos kernels it is necessary to manyally correct a symlink in /dev/dri. Because even after the user finally has a working agpgart, Illumos' DDI/DKI for some reason creates a wrong symlink during initialization. Example: GOOD: ls -al /dev/dri total 11 drwxr-xr-x 5 root root 5 Nov 24 10:41 . drwxr-xr-x 282 root root 282 Dec 10 17:32 .. lrwxrwxrwx 1 root root 36 Nov 24 09:55 card0 -> ../../devices/pci@0,0/display@2:drm0 lrwxrwxrwx 1 root root 42 Nov 24 10:02 controlD64 -> ../../devices/pci@0,0/display@2:controlD64 root@opensxce:~# BAD (as on Illumos or any other older Solaris kernels before S11 snv_175) : ls -al /dev/dri total 11 drwxr-xr-x 5 root root 5 Nov 24 10:41 . drwxr-xr-x 282 root root 282 Dec 10 17:32 .. lrwxrwxrwx 1 root root 42 Nov 24 10:41 card0 -> ../../devices/pci@0,0/display@2:controlD64 lrwxrwxrwx 1 root root 36 Nov 24 09:55 card1 -> ../../devices/pci@0,0/display@2:drm0 root@opensxce:~# (can be fixed by simply renaming /dev/dri/card0 to /dev/dri/controlD64 in the boot scripts, for each boot, until the real solution is found in Illumos' DDI/DKI bindings, which so far has a low priority until the rest works) On old CPU's such as my 2700k (finally no longer only a Celeron G530, thanks to your donations!) it is sufficient for getting a working agpgart to wget, uncompress and install http://svr4.opensxce.org/201405/i386/5.11/sunw_agp-OpenSXCE__Illumos20140505%2cREV%3d2014.05.07.03.16-SunOS5.11-i386-SUNW.pkg.gz [or to use pkgutil if you are on OpenSXCE2014.05). Until the real problems are solved, there is no need to upload an updated version with newer pciids. Now - here my proposed diff in 2 versions plus also the binary i915 and drm modules from 2 weeks ago. Again: I won't provide howto instructions, because the audience of this post is very small and those who can use anything from this letter, won't need such instrcutions. The only real question was and is: Why does this work (bypassing all gfxp 11.1++ interfaces) nevertheless only on 11.1++ and panics the host early during X11 initialization on 11.0 and Illumos. Meanwhile I have the suspicion (judging from binutils) that in the more modern gfxp driver the frame buffer gets mmapp'ed. However, unlike Illumos or old OpenSolaris, in S11.0 this code seems to be already inside gfxp: $ nm gfx_private|grep setup BFD: gfx_private: warning: sh_link not set for section `.eh_frame' U ddi_regs_map_setup U devmap_devmem_setup U devmap_umem_setup 00000000000006bc T gfxp_ddi_segmap_setup 0000000000000a00 T gfxp_devmap_umem_setup 00000000000026f4 t gfxp_setup_fbcons U pci_config_setup BUT DESPITE THIS, it panics on 11.0 due to attempted dereferencing of a NULL pointer triggering a TRAP. Normally I would never publish such instable non-functional stuff. Ahh, ps.: On 11.1++ this stuff works if built with Studio. But forget getting back to the Text console after X11 was already up. It is possible to enter commands afterwards, but only blindly without seeing anything (console is completely srapped). However - restarting X11 or rebooting will function (on S11.1++). Only that you won't see what you typed. This happens in this case not because of incomplete cleanup, but has to do with structs not properly initialized and not correctly assigned to the correct objects (especially fb_info). Neverthe less X11 and compize (even with gnome) do work fine on S11.1++, yet not on 11.0 or Illumos). The return2console issue can be addressed after we finally have it working on 11.0 and Illumos. As for" gfxp is "not" a moving target: nm suggests otherwise. And replacing newer or older versions of gfxp (as possible with i915/drm and agpgart [all related submodules]) CANNOT be done with gfxp, neitehr upwards, now downwards. Missing symbols (depends directly on the /platform/i86pc/kernel/amd64/unix itself). Even replacing Grub1 against Grub2 or vide versa (Such as Solaris 11.1 booted from Grub1) : No difference. As for the panic backtrace that I usually got 2 weeks ago (today with gcc a different one, and no matter if on 11.1++ or earlier - never works, I'm a bit confused if that's really a gcc vs. studio issue, or realted to some other change during the diff created today, dammit), here how it would look like, I uload the kernel dumps to opensxce.org/kms_dump in 10 minutes.
