Hi Robert, After trying to write a proper patch for Nouveau, we realised we were missing a few pieces of information. ----- Mail original ----- > Hi Robert, > > Thanks a lot for your response! > > ----- Mail original ----- > > On Wed, Oct 22, 2014 at 12:55:23AM +0200, pierre.morrow at free.fr > > wrote: > > [...] > > > After some investigation, I found

Hi, When using acceleration with Nouveau on MacBook Pros with an 9400M (NVAC) card, a PFIFO interrupt 0x00400000 is thrown during the initialisation of that card (sometime after PFIFO and PGRAPH initialisation) and the laptop will lockup [1], forcing users to load Nouveau without acceleration. After some investigation, I found that enabling bit 1 of register 100c14 fixes the issue on that card.

Hi! I am creating a application that does a lot of background processing. For this I am using a queue (starling in my case...) and several pollers that will get a message from the queue and execute some code corresponding do it. The code that these pollers process looks a lot like some code in methods included in some of my rails application controllers. I wanted to DRY this a little bit, so I

Does anybody know, is there any way to use post-script fonts (.pfm for windows or .pfb for *nix) in windows application running throw the Wine (eg. Adobe Photoshop or Macromedia Flash)? I copy fonts to the wine's Windows/Fonts folder but no app see them :((

The 100c08 scratch page is mapped using dma_map_page() before the TTM layer has had a chance to set the DMA mask. This means we are still running with the default of 32 when this code executes, and this causes problems for platforms with no memory below 4 GB (such as AMD Seattle) So move the dma_map_page() to the .init hook, and set the streaming DMA mask based on the MMU subdev parameters before

I just for the first time attempted to install Cacti from the RPMForge repo on CentOS 4.4. And I have to say that it hasn't gone very well at all. I have installed Cacti on Fedora a good 20 times with absolutely no problem. Basically the default rrds/graphs for localhost are generated but no other rrds/graphs are generated. When I look at the poller cache or snmp cache I see all the data.

This v4 is now a 3 piece series, after Alexandre pointed out that both GF 100 and NV50 are affected by the same issue, and that a related issue has been solved already for Tegra in commit 9d0394c6bed5 ("drm/nouveau/instmem/gk20a: set DMA mask early"). The issue that this series addresses is the fact that the Nouveau driver invokes the DMA API before setting the DMA mask. In both cases

The DMA API is the recommended way to map pages no matter what the underlying bus is. Use the DMA functions for page mapping and remove currently existing wrappers.
