2011-04-19drm/nouveau: fix allocation of notifier objectMarcin Slusarz
Commit 73412c3854c877e5f37ad944ee8977addde4d35a ("drm/nouveau: allocate kernel's notifier object at end of block") intended to align end of notifier block to page boundary, but start of block was miscalculated to be off by -16 bytes. Fix it. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Cc: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-03-16Merge commit '5359533801e3dd3abca5b7d3d985b0b33fd9fe8b' into drm-core-nextDave Airlie
This commit changed an internal radeon structure, that meant a new driver in -next had to be fixed up, merge in the commit and fix up the driver. Also fixes a trivial nouveau merge. Conflicts: drivers/gpu/drm/nouveau/nouveau_mem.c
2011-03-04drm/nouveau: allocate kernel's notifier object at end of blockBen Skeggs
The nv30/nv40 3d driver is about to start using DMA_FENCE from the 3D object which, it turns out, doesn't like its DMA object to not be aligned to a 4KiB boundary. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-10-04drm/nouveau: Minor refactoring/cleanup of the fence code.Francisco Jerez
Mainly to make room for inter-channel sync. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-10-04drm/nv50: prevent (IB_PUT == IB_GET) for occurring unless idleBen Skeggs
Should fix a DMA race condition I've never seen myself, but could be the culprit in some random hangs that have been reported. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-09-24drm/nouveau: remove nouveau_gpuobj_ref completely, replace with sanityBen Skeggs

2010-09-24drm/nouveau: remove second map of notifier boBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-07-13drm/nouveau: remove left-over !DRIVER_MODESET pathsBen Skeggs
It's far preferable to have the driver do nothing at all for "nomodeset". Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-03-10drm/nv50: add a memory barrier to pushbuf submissionMaarten Maathuis
- This is useful for vram pushbuffers that are write combined. - pre-nv50 has one too (in WRITE_PUT). Signed-off-by: Maarten Maathuis <madman2003@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-02-25drm/nouveau: new gem pushbuf interface, bump to 0.0.16Ben Skeggs
This commit breaks the userspace interface, and requires a new libdrm for nouveau to operate again. The multiple GEM_PUSHBUF ioctls that were present in 0.0.15 for compatibility purposes are now gone, and replaced with the new ioctl which allows for multiple push buffers to be submitted (necessary for hw index buffers in the nv50 3d driver) and relocations to be applied on any buffer. A number of other ioctls (CARD_INIT, GEM_PIN, GEM_UNPIN) that were needed for userspace modesetting have also been removed.

2010-02-25drm/nv50: make pushbuf dma object cover entire vmBen Skeggs
This allows us to submit push buffers from any memtype to the hardware. We'll need this ability for VRAM index buffers at some point. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-02-25drm/nv50: switch to indirect push buffer controlsBen Skeggs
PFIFO on G80 and up has a new mode where the main ring buffer is simply a ring of pointers to indirect buffers containing the actual command/data packets. In order to be able to implement index buffers in the 3D driver we need to be able to submit data-only push buffers right after the cmd packet header, which is only possible using the new command submission method. This commit doesn't make it possible to implement index buffers yet, some userspace interface changes will be required, but it does allow for testing/debugging of the hardware-side support in the meantime.

2010-01-17drm/nouveau: fix a race condition in nouveau_dma_wait()Ben Skeggs
Can be triggered easily on certain cards (NV46 and NV50 of mine) by running "dmesg", the DRM's channel will lockup. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-01-10drm/nouveau: initialise DMA tracking parameters earlierBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-01-10drm/nouveau: use dma.max rather than pushbuf size for checking GET validityBen Skeggs
Some upcoming G80 DMA changes will depend on this, but it's split out for bisectibility just in case it causes some unexpected issues. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-01-10drm/nouveau: Allocate a per-channel instance of NV_SW.Francisco Jerez
It will be useful for various synchronization purposes, mostly stolen from "[PATCH] drm/nv50: synchronize user channel after buffer object move on kernel channel" by Maarten Maathuis. Signed-off-by: Francisco Jerez <currojerez@riseup.net>
2009-12-11drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs
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.
