2015-01-22drm/nouveau: remove symlinks, move core/ to nvkm/ (no code changes)Ben Skeggs72-32641/+0
The symlinks were annoying some people, and they're not used anywhere else in the kernel tree. The include directory structure has been changed so that symlinks aren't needed anymore. NVKM has been moved from core/ to nvkm/ to make it more obvious as to what the directory is for, and as some minor prep for when NVKM gets split out into its own module (virt) at a later date.

2014-12-02drm/gf100-/gr: return non-fatal error code when fw not presentBen Skeggs1-1/+1
This allows the module to load without acceleration. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-10-20drm/gt215/gr: fix initialisation on gddr5 boardsBen Skeggs1-2/+8
The binary driver modifies the default context to have this value, rather than 0x3d0040, *after* it's filled the buffer with the usual golden data. We don't really have anything in place to locate the correct offset to do these type of modifications outside of the generation function, so this will have to do.

2014-08-15drm/gf100-/gr: fix -ENOSPC detection when allocating zbc table entriesBen Skeggs1-0/+6
Spotted by Coverity. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-08-10drm/gf100-/gr: implement the proper SetShaderExceptions methodBen Skeggs8-17/+45
We have another version of it implemented in SW, however, that version isn't serialised with normal PGRAPH operation and can possibly clobber the enables for another context. This is the same method that's implemented by the NVIDIA binary driver. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-08-10drm/gf100-/gr: remove some broken ltc bashing, for nowBen Skeggs13-58/+0
... and hope that the defaults are good enough. This was always supposed to be a read/modify/write thing anyway, so we're writing very wrong stuff for some boards already. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-08-10drm/gf100-/gr: unhardcode bundle cb configBen Skeggs13-41/+100
Should be the same values as before, except: GF117 has smaller buffer allocated, as per register setup. GK20A now uses values from Tegra driver, not GK104's. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-08-10drm/gf100-/gr: improve initial context patch list helpersBen Skeggs4-20/+51
Removes need for fixed buffer indices, and allows the functions utilising them to also be run outside of context generation. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-08-10drm/gf100-/gr: add support for zero bandwidth clearBen Skeggs9-11/+257
Default ZBC table is compatible with binary driver defaults. Userspace will need to be updated to take full advantage of this feature, however, some applications will see a performance boost without updated drivers. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-08-10drm/nouveau/disp: audit and version display classesBen Skeggs10-10/+0
The full object interfaces are about to be exposed to userspace, so we need to check for any security-related issues and version the structs to make it easier to handle any changes we may need in the future. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-08-10drm/nve4/graph: do not crash if no power device presentAlexandre Courbot1-1/+2
Detect and workaround the absence of a power device so chips that do not feature one (e.g. GK20A) can still use this driver. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-08-10drm/gk208-/gr: stop touching 0x260 inappropriatelyBen Skeggs5-11/+11
As a side note.. It's a bit hard to figure out how to name this commit.. GK20A is NVEA, which is before NV108 (GK208).. Confusing. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-06-17drm/nv50/gr: remove an unneeded write while initialising PGRAPHPierre Moreau1-1/+0
The blob does not seem to write at that place for my NVAC, though it does for my NV96, agreeing with what is done in the if/else structure below.

2014-06-10drm/nouveau/graph: add GK20A supportAlexandre Courbot6-9/+120
Add a GR device for GK20A based on NVE4, with the correct classes definitions (GK20A's 3D class is 0xa297). Most of the NVE4 code can be used on GK20A, so make relevant bits of NVE4 available to other chips as well.

2014-06-10drm/nouveau/graph: pad firmware code at load timeAlexandre Courbot1-0/+4
Pad the microcode to a multiple of 0x40 words, otherwise firmware will fail to run from non-prepadded firmware files. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Reviewed-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-06-10drm/nouveau/graph: enable when using external fwAlexandre Courbot1-3/+7
nvc0_graph_ctor() would only let the graphics engine be enabled if its oclass has a proper microcode linked to it. This prevents GR from being enabled at all on chips that rely exclusively on external firmware, even though such a use-case is valid. Relax the conditions enabling the GR engine to also include the case where an external firmware has also been loaded. Also switch to external firmware if the graph class has no microcode linked to it. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-03-26support for platform devicesAlexandre Courbot3-4/+4
Upcoming mobile Kepler GPUs (such as GK20A) use the platform bus instead of PCI to which Nouveau is tightly dependent. This patch allows Nouveau to handle platform devices by: - abstracting PCI-dependent functions that were typically used for resource querying and page mapping, - introducing a nv_device_is_pci() function that allows to make PCI-dependent code conditional, - providing a nouveau_drm_platform_probe() function that takes a GPU platform device to be probed. Core code as well as engine/subdev drivers are updated wherever possible to make use of these functions. Some older drivers are too dependent on PCI to be properly updated, but all newer code on which future chips may depend should at least be runnable with platform devices.
