[Nouveau] [Bug 27501] MacBook Pro 5, x unable to boot [NV96 + NVAC]
https://bugs.freedesktop.org/show_bug.cgi?id=27501 --- Comment #63 from Pierre Moreau pierre.mor...@free.fr --- For those with a dual card setup (NVAC + NV96), you should follow bug 86537 if you want updates on fixing the NV96. Unfortunately there hasn't been much progress, apart from finding that changing some register's value makes it work (most likely by disabling some things, so it is not a valid fix). -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

Patch is now present in 3.19-rc4, closing this bug report as solved.
For those who have the NV96 along the NVAC, you need to use l3iggs technique
and reset+rescan (echo 1 /sys/bus/pci/devices/:02:00.0/{reset,rescan})
the NV96 **before** loading Nouveau to avoid a hang when starting X and another
hang when trying to power off the NV96.

Thanks very much for your work on this Pierre (and thanks to your Nvidia contacts too). With your previous patch, my NVAC was able to start a fully accelerated gnome session via X, although it was very unstable and was quite unusable (however, weston seemed to work fine for me with that patch). With this latest patch, things seem quite stable. I'm writing this from a google-chrome browser in gnome-shell/X and generally things seem to be working so far. ~l3iggs -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

https://bugs.freedesktop.org/show_bug.cgi?id=27501 --- Comment #56 from l3iggs j...@greyltc.com --- Created attachment 109963 -- https://bugs.freedesktop.org/attachment.cgi?id=109963action=edit 9400M dmesg What follows is my partially working workaround for my 9400M in my MacBook Pro 5,1. For my fully working workaround for my 9600M GT see https://bugs.freedesktop.org/show_bug.cgi?id=86537 The following was tested with a kernel 3.18-rc6 (without applying any of the patches here): (1) Append 'modprobe.blacklist=nouveau' to the kernel boot parameters This allows the system to boot. (2) Once booted, as root, reset the 9400M GPU: 'echo 1 /sys/bus/pci/devices/:03:00.0/reset' (3) 'echo 1 /sys/bus/pci/devices/:03:00.0/rescan' (4) 'echo 1 /sys/bus/pci/devices/:02:00.0/remove' This completely removes the 9600M GT GPU from the system so nouveau does not use in when we load the module in the next step. (5) 'modprobe nouveau' where :03:00.0 is the PCI address of my 9400M and :02:00.0 is the PCI address of my 9600M GT. Nouveau seemingly loads fine for the 9400M, however I find myself unable to actually use my 9400M GPU for anything (while repeating the same above steps for my 9600M GT works fine). For example, starting gdm with the 9400M does nothing. I believe this is because the 9400M GPU is not connected to any display (since it was not selected in OSX). I've attached dmesg logs for loading nouveau for each of the GPUs in my laptop here. Notice that for the working 9600M GT, the log shows: nouveau [ DRM] allocated 1440x900 fb: 0x7, bo 88014750d400 1449x900 is the native resolution of my laptop's display. while for the non-working 9400M, the log shows: nouveau :03:00.0: No connectors reported connected with modes [drm] Cannot find any crtc or sizes - going 1024x768 nouveau [ DRM] allocated 1024x768 fb: 0x5, bo 88014715a400 I think I'm pretty close to having a universal working solution for both GPUs here. Does anyone know how I can connect my 9400M GPU with my display? I've tried fiddling a bit with xrandr after loading nouveau for the 9400M, but it seems to always report no displays found. -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

If so, could you try to modify the patch a bit, like: - removing the write to 0x100c1c; - if removing the write doesn't work, changing the offset applied to priv-r100c08 maybe testing all 4-multiples should do it, from 0 to 28. I've only tested the 9600 about 10 times, but I've always had corruption. I will try your changes and see if it makes a difference. No change, unfortunately. I first removed the write, then tried each of the offsets. After switching to Higher Performances in OS X, I understand what you were explaining to me about having both cards enabled but having corrupted screen only in one case. With that in mind, tweaking the patch can't fix the corruption as we are modifying things on the 9400M but it's the 9600M GT which is responsible for displaying; I suggest opening another bug report for that. I'll continue working on this patch and find how to use 0x100c1c before switching to the 9600M GT. Some side notes about what is wrong with the 9600M GT: - screen corruption when using it to drive the display - interrupt 0x0400 + lockup when starting X with acceleration on for 9400M and 9600M GT, and the 9400M is driving the screen - when powering it down using vgaswitcheroo: * if accel isn't enabled: E[ PDISP][:02:00.0][0xc000887d][880137b94400] fini: 0x490e0008 E[ PDISP][:02:00.0][0xc000887d][880137b94400] failed suspend, -16 * if accel is enabled: flush timeout + (interrupt 0x0400 iirc) + lockup -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

I use the efi stub loader with refind bootloader. Refind doesn't have an option to use outb as in grub. I have set OSX preferences to battery saving, so that the firmware sets up the 9400 initially, but the 9600 is still technically enabled. It shows up in lspci, etc. Whenever I test the 9600, I change the setting in OSX back to performance. So yes, with both cards enabled, the 9400 works without corruption.

https://bugs.freedesktop.org/show_bug.cgi?id=27501 --- Comment #41 from Pierre Moreau pierre.mor...@free.fr --- Hi Thomas, (In reply to comment #39) Pierre, I have tested your patch with the 9400M in my macbookpro 5,2. The card boots correctly with acceleration enabled, and loads GDM. GDM looks completely correct, but hangs on login with a cursor on a grey screen. It's possible that LXDE, KDE, or some other DE might work, but gnome-shell never loads. I will try slim/lxde when I get a chance. Oh... I didn't test with Gnome or KDE, as I'm using Awesome (which works fine). Maybe if you deactivate composing it will be better (as a temporary solution)? I'm working on improving the patch: at the moment, it turns some bits on (enabling some features?), but the blob also writes some things (feature configuration?) before turning each bit on. So maybe finding what those things are and implementing them will fix the errors. At this point I can switch back to VT where I notice some nouveau errors in dmesg. Killing GDM (and x11 with it) produces a kernel panic. Next I booted with the 9600GT with acceleration disabled. The display looks correct with efifb, but loading nouveau scrambles the VT. I have seen it once or twice too, but not at each boot. On a similar note, I sometime get PDISP errors about an unknown method when loading Nouveau, but as it rarely happen, I haven't tried to fix it yet. I'll have a look at both errors later on.

https://bugs.freedesktop.org/show_bug.cgi?id=27501 --- Comment #39 from thomas guruto...@gmail.com --- Pierre, I have tested your patch with the 9400M in my macbookpro 5,2. The card boots correctly with acceleration enabled, and loads GDM. GDM looks completely correct, but hangs on login with a cursor on a grey screen. It's possible that LXDE, KDE, or some other DE might work, but gnome-shell never loads. I will try slim/lxde when I get a chance. At this point I can switch back to VT where I notice some nouveau errors in dmesg. Killing GDM (and x11 with it) produces a kernel panic. Next I booted with the 9600GT with acceleration disabled. The display looks correct with efifb, but loading nouveau scrambles the VT.

https://bugs.freedesktop.org/show_bug.cgi?id=27501 --- Comment #37 from Joanand macgyver...@web.de --- Hi Pierre, Both patches seems to work (tested 1x on 3.17.rc6). Xorg-x11 starts with fluxbox, messages show that 9600 is unacclerated and 9400 is acclerated. There is are two errors in your patch option for disabling accleration for given chipset: * The entries DRM_DEBUG_DRIVER are not available on 3.17.rc6, but it works either way. * In the kernel 3.17 it should be if (nouveau_noaccel || !nouveau_fifo(device) /*XXX*/) not only if (nouveau_noaccel) Terminating xorg-x11 crashed, probably because I switched off discrete graphichs adapter after starting xorg. Someone else should check. Further testing is in queue. The previous patch you have sent: It solved a problem I had in the past: System kernel panics if the lid is closed during startup! Thanks. Do you think that acceleration for 9600M will be possible sometime? BR.

Hi Joanand, I based my patches on the linux-3.18 branch of Nouveau's repo, which is more up-to-date than 3.17-rc6: this explains the if (nouveau_noaccel) at least. Great for the kernel panic! I noticed that using the patches, screen resumes correctly when resuming the computer, rather than staying completely black. Well, I'll work 9600M Gt acceleration, but I can't say if I'll succeed, nor when. ;) Best regards -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

Use nouveau.chipsetnoaccel=0x96 in this case to disable acceleration on the 9600M GT. How about changing noaccel instead to optionally be able to take a list of pci addresses? (Or even just one to start...)

https://bugs.freedesktop.org/show_bug.cgi?id=27501 --- Comment #33 from Joanand macgyver...@web.de --- I confirm that the patch works, screen is NOT scrambled. Unsing my ancient gpupwr-programm to deactivate 9600M, I am able to start xorg-x11 + fluxbox with accleration. Pierre, thank you very much. I have seen that vga-switcheroo does not get started, probably due to the 9600M fallen off the bus. I cannot await your fix for 9600M with acceleration. BR. (In reply to comment #29) Created attachment 106246 [details] [review] Temporary patch for 9400M GT acceleration Could you please test this patch along with Ilia's one? It should fix acceleration on the 9400M GT, allowing you to boot without nouveau.noaccel=1 and to launch X. I'll need to refine the patch a bit as it introduces some errors on the 9600M. Another patch may be mandatory to get both cards to get along: for now, the laptop seems to be hitting an infinite loop when launching X with both cards enabled. -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

https://bugs.freedesktop.org/show_bug.cgi?id=27501 --- Comment #30 from Rolf Offermanns rolf.offerma...@gmx.net --- Pierre, the patch works for me (MacBookPro5,2). I had to modify Ilia's patch to have MacBookPro5 in the DMI_MATCH instead of MacBook5 and now I can boot into a KDE5 session with the nouveau driver. I checked the xorg log file and verified that it is indeed using hardware accelaration. I used a fresh git clone of Linus tree for the test. Let me know if you need further information.

I tested it on my laptop, but as it sometimes behaves in a strange way, I preferred to get confirmation by at least someone else. :) I'll see later today if I can get both cards to get along without locking up the GPU.

https://bugs.freedesktop.org/show_bug.cgi?id=27501 --- Comment #28 from Pierre Moreau pierre.mor...@free.fr --- I've made some progress on this bug, enabling Nouveau to be loaded with acceleration enabled. However, X is **absolutely not** usable: complete garbage screen, lots of Nouveau errors, only action available is power down the computer (or reboot). But for using Nouveau with acceleration in console mode, it works fine. There are (at least) two main problems: * 9400M acceleration is broken (resulting in Nouveau locking up on boot); * it seems there is a lockup when starting a working X with both cards enabled. -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
