similar to: [PATCH] drm/nouveau: fix nouveau_mm/nouveau_mm_node leak

Signed-off-by: Marcin Slusarz <marcin.slusarz at gmail.com> --- This patch relies on "drm/nouveau: remove >1 sclass support from nouveau_parent_create_". There are *many* *more* code paths without proper error handling - I counted at least 106 in 41 functions. If someone would like to do a bit of janitorial work I marked those code paths and uploaded "patch" here:

Allocating type=0 marks the memory as free. This allows the ltcg memory to be allocated twice. Add a BUG_ON in core/mm.c to prevent this ever happening again. Additionally some registers were not initialized in init, this causes them to be uninitialized after suspend. Signed-off-by: Maarten Lankhorst <maarten.lankhorst at canonical.com> --- diff --git

We want to be able to guarantee the location of the allocated buffer object if we're going to be able to reliably allocate the existing framebuffer at startup.

- Use the "direct" objects that previously only the kernel fifo had. - This avoids corruption on some buffer moves.

Hi folks ! So I've been trying to figure out what it would take to make nouveau work properly on architectures where PAGE_SIZE isn't 4k such as most ppc64's. An initial patch from Dave fixed a bogon in nv41.c nv41_vm_map_sg() which was trying to handle the case at that low level, but this isn't enough, and after a bit of digging, I also think that's not the right approach:

Hello, I am kernel engineer working on PV-OPS kernel trying to get it work in Dom0 with an NVidia (NV30 right now) card. But there are issues, such as that the pv-ops kernel has a different understanding of memory (for details check out: http://wiki.xensource.com/xenwiki/XenPVOPSDRM). I've fleshed out most of them (like GART had the wrong phys addresses, ouch!), but the one that I am

Twice in a little over a week, nouveau has locked up on my system with an Asus ENGT430 that is "Detected [as] an NVc0 generation card (0x0c1080a1)" at boot time. OS is Mageia 2, kernel 3.4.45-server-1.mga2. At the time of both lockups, I had a couple dozen Firefox windows plus several other miscellaneous windows open. Here are the some snippets from /var/log/messages a few days before

- In the case of nvbo->head it is really important to avoid an OOPS if ttm_buffer_object_init fails.

Hello all, this series includes a wide range of fixes - from a few month's old one-liners from Andreas Heider regarding vga_switcheroo, via a null pointer dereference and double memory allocation, to a buffer overflow.

It's probably impossible to hit it now on mainline kernel. I only noticed it because one of my debugging patches uses it.

Fixes regression introduced in commit 861d2107 "drm/nouveau/fb: merge fb/vram and port to subdev interfaces" nv50_fb_vram_{new,del} functions were changed to use nouveau_subdev->mutex instead of the old nouveau_mm->mutex. nvc0_fb_vram_new still uses the nouveau_mm->mutex, but nvc0 doesn't have its own fb_vram_del function, using nv50_fb_vram_del instead. Because of this, on
