      drm/nv20: Use the nv30 CRTC bandwidth calculation code. · 4295f188
      Francisco Jerez authored
      
      
      nv2x CRTC FIFOs are as large as in nv3x (4kB it seems), and the FIFO
      control registers have the same layout: we can make them share the
      same implementation.
      
      Previously we were using the nv1x code, but the calculated FIFO
      watermarks are usually too low for nv2x and they cause horrible
      scanout artifacts. They've gone unnoticed until now because we've been
      leaving one of the bandwidth regs uninitialized (CRE 47, which
      contains the most significant bits of FFLWM), so everything seemed to
      work fine except in some cases after a cold boot, depending on the
      memory bandwidth and pixel clocks used.

      drm/nouveau: Add DRM driver for NVIDIA GPUs · 6ee73861
      Ben Skeggs authored
      
      
      This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.
      
      This driver is a KMS-based driver and requires a compatible nouveau
      userspace libdrm and nouveau X.org driver.
      
      This driver requires firmware files not available in this kernel tree,
      interested parties can find them via the nouveau project git archive.
      
      This driver is reverse engineered, and is in no way supported by nVidia.
      
      Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
      is available, and the kms driver should support driving nearly all
      output types (displayport is under development still) along with supporting
      suspend/resume.
      
      This work is all from the upstream nouveau project found at
      nouveau.freedesktop.org.
