2017-11-03drm/nouveau/bios: make const arrays hwsq_signature and edid_sig staticColin Ian King
Don't populate arrays hwsq_signature and edid_sig on the stack but instead make them static.

2017-06-16drm/nouveau/disp: introduce acquire/release display path methodsBen Skeggs
These exist to give NVKM information on the set of display paths that the DD needs to be active at any given time. Previously, the supervisor attempted to determine this solely from OR state, but there's a few configurations where this information on its own isn't enough to determine the specific display paths in question: - ANX9805, where the PIOR protocol for both DP and TMDS is TMDS. - On a device using DCB Switched Outputs. - On GM20x and newer, with a crossbar between the SOR and macro links. After this commit, the DD tells NVKM *exactly* which display path it's attempting a modeset on. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2015-08-28drm/nouveau/nvif: simplify and tidy library interfacesBen Skeggs
A variety of tweaks to the NVIF library interfaces, mostly ripping out things that turned out to be not so useful. - Removed refcounting from nvif_object, callers are expected to not be stupid instead. - nvif_client is directly reachable from anything derived from nvif_object, removing the need for heuristics to locate it - _new() versions of interfaces, that allocate memory for the object they construct, have been removed. The vast majority of callers used the embedded _init() interfaces. - No longer storing constructor arguments (and the data returned from nvkm) inside nvif_object, it's more or less unused and just wastes memory.

2015-01-22drm/nouveau: finalise nvkm namespace switch (no binary change)Ben Skeggs
The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-01-22drm/nouveau/nvif: namespace of nvkm accessors (no binary change)Ben Skeggs
NVKM is having it's namespace switched to nvkm_, which will conflict with these functions (which are workarounds for the fact that as of yet, we still aren't able to split DRM and NVKM completely).

2014-03-26support for platform devicesAlexandre Courbot
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.

2013-04-26drm/nv04/disp: hide all the cruft away in its own little holeBen Skeggs
It'd be pretty awesome if someone would care enough to port this all properly to a class interface, perhaps submitting a command stream to the core via a sw object on PFIFO (emulating how EVO works basically, and also what nvidia have done forever..).. But, this seems unlikely given how old this hardware is now, so, lets just hide it away. There's a heap of other bits and pieces laying around that are still tangled. I'll (re)move them in pieces.

2012-10-03Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linuxLinus Torvalds
Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked." Tons of conflicts mostly due to silly include line changes, but mostly mindless.

This reverts commit d06221c0617ab6d0bc41c4980cefdd9c8cc9a1c1. It turns out to trigger the "BUG_ON(!PageCompound(page))" in kfree(), apparently because the code ends up trying to free somethng that was never kmalloced in the first place. BenH points out that the patch was untested and wasn't meant to go into the upstream kernel that quickly in the first place.

2012-04-02nouveau/bios: Fix tracking of BIOS image dataBenjamin Herrenschmidt
The code tries various methods for retreiving the BIOS data. However it doesn't clear the bios->data pointer between the iterations. In some cases, the shadow() method will fail and not update bios->data at all, which will cause us to "score" the old data and incorrectly attribute that score to the new method. This can cause double frees later when disposing of the unused data. Additionally, we were not freeing the data for methods that fail the score test (we only freed when a "best" is superseeded, not when the new method has a lower score than the exising "best"). Fix that as well. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
