similar to: More on GART vertex buffer corruption

It seems that Noveau is assuming that once the FIFO pointer is past a command, that command has finished executing, and all the buffers it used are no longer needed. However, this seems to be false at least on G71. In particular, the card may not have even finished reading the input vertex buffers when the pushbuffer "fence" triggers. While Mesa does not reuse the buffer object itself,

Hi Nouveau folks, I've been encountering some corruption on pixmaps for a while now, and it seems like the problem comes from the DFS/UTS (Download From Screen / Upload To Screen). In fact, I'm pretty sure the problem comes from there as screenshots are garbled and so does a few more things. I may have time to dig this up, where should I start, is there some documentation on the NVS

What does the following EDAC problem means? The machine is a AMD 64bit box running Centos 5. It looks like some problems aroung AMD DRAM Memory controller. But what does it really mean b/c most of my AMD boxes has these messages in /var/log/messages. Please help. ...

This patch enlarges the PCI GART aperture to 512 MB. The current 64MB aperture is too small and should be enlarged. The optimal amound may be card/system-dependent, so a more sophisticated approach may be preferable. In particular, if RAMIN is less than 1MB, a 512MB aperture won't fit.

Changes in v2: - Compute size based on ramin_rsvd_size This patch enlarges the PCI GART aperture to 512 MB, or the space covered by a DMA object filling half RAMIN. The current 64MB aperture is too small and should be enlarged. The optimal amound may be card/system-dependent, so a more sophisticated approach may be preferable. Could anyone with an nv04 test whether this doesn't break there?

If you want to access gart as linear, don't specify a non-zero storage type.

Keeping it in VRAM wastes CPU time, because cursor_set ioctl reads handed BO back to RAM, just to write it to actual cursor BO. Here (nv92/core i7), this patch decreases overall cpu usage of drmmode_load_cursor_argb from 4.6ms to ~90us and lets nv50_crtc_cursor_set disappear from perf traces. --- I considered accelerating kernel-side copying with GPU, but it turns out that: - it's slower

Most graphics cards nowadays have a multiple of this limit as their vram, so limiting GART doesn't seem to make much sense.

I am trying to figure out why the ttm_bo_vm_fault is stitching pages from the GART instead of the pages allocated via DRM_NOUVEAU_GEM_NEW. And also why OUR_RINGp is writing 16, 256 and 512 bytes of zero filled data *1 in the GART? Perhaps I should mention that I know _why_ it is taking the pages from the GART and giving them to the userland - but I don't know if that is correct way of doing

Hey everyone, I realize that people asking about PCI passthrough has been thoroughly beaten to death many a time, however I couldn''t find the answer to these questions anywhere (and I''d really like to know :P) so please just bare with me. I know the GART built into AMD chipsets can act as a "mini IOMMU" and do DMA translation but not protection/isolation. However,

Unfortunately AGP is still to widely used as we could just drop support for using its GART. Not using the AGP GART also doesn't mean a loss in functionality since drivers will just fallback to the driver specific PCI GART. For now just deprecate the code and don't enable the AGP GART in TTM even when general AGP support is available. Please comment, Christian.

Hi, i was the one who had problems with the start_tls function. I applied the patch yesterday. But now the compiling doesn't work anymore.
