From 6ee738610f41b59733f63718f0bdbcba7d3a3f12 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 11 Dec 2009 19:24:15 +1000 Subject: drm/nouveau: Add DRM driver for NVIDIA GPUs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.

This should avoid a race condition on nv0x, if we're doing it with actual PGRAPH objects and a there's a fence within the FIFO DMA fetch area when a context switch kicks in. In that case we get an ILLEGAL_MTHD interrupt as expected, but the values in PGRAPH_TRAPPED_ADDR aren't calculated correctly and they're almost useless (e.g. you can see ILLEGAL_MTHDs for the now inactive channel, with a wrong offset/data pair).
