Hi, Please find attached the patches which I currently use on my desktop machine for dual head with the randr branch to fix the issues which I found. They may help others as well but may e.g. also disable the Xv blitter which might be working for some (but didn't on my card) - more information is found in the text comments in the patches. I have to hurry so this is short, will be back.

I've been doing some testing and it seems that glyphs (typically smaller than a page size on nv50) render slow'ish sometimes, mostly due to the many trips to the kernel (drm_addmap_core is the symbol that shows up). Ofcource this was a benchmark, but it does leave me wondering, do we really need need to call the kernel for every little pixmap? Also from a memory point of view, because a single page can theoretically contain 32 pixmaps. Is it problematic to combine small allocatio...
