* Merge branch 'linux-3.17' of git://anongit.freedesktop.org/git/nouveau/linux-2.6Linus Torvalds2014-08-09262-5795/+12140
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull nouveau drm updates from Ben Skeggs: "Apologies for not getting this done in time for Dave's drm-next merge window. As he mentioned, a pre-existing bug reared its head a lot more obviously after this lot of changes. It took quite a bit of time to track it down. In any case, Dave suggested I try my luck by sending directly to you this time. Overview: - more code for Tegra GK20A from NVIDIA - probing, reclockig - better fix for Kepler GPUs that have the graphics engine powered off on startup, method courtesy of info provided by NVIDIA - unhardcoding of a bunch of graphics engine setup on Fermi/Kepler/Maxwell, will hopefully solve some issues people have noticed on higher-end models - support for "Zero Bandwidth Clear" on Fermi/Kepler/Maxwell, needs userspace support in general, but some lucky apps will benefit automagically - reviewed/exposed the full object APIs to userspace (finally), gives it access to perfctrs, ZBC controls, various events. More to come in the future. - various other fixes" Acked-by: Dave Airlie <airlied@redhat.com> * 'linux-3.17' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (87 commits) drm/nouveau: expose the full object/event interfaces to userspace drm/nouveau: fix headless mode drm/nouveau: hide sysfs pstate file behind an option again drm/nv50/disp: shhh compiler drm/gf100-/gr: implement the proper SetShaderExceptions method drm/gf100-/gr: remove some broken ltc bashing, for now drm/gf100-/gr: unhardcode attribute cb config drm/gf100-/gr: fetch tpcs-per-ppc info on startup drm/gf100-/gr: unhardcode pagepool config drm/gf100-/gr: unhardcode bundle cb config drm/gf100-/gr: improve initial context patch list helpers drm/gf100-/gr: add support for zero bandwidth clear drm/nouveau/ltc: add zbc drivers drm/nouveau/ltc: s/ltcg/ltc/ + cleanup drm/nouveau: use ram info from nvif_device drm/nouveau/disp: implement nvif event sources for vblank/connector notifiers drm/nouveau/disp: allow user direct access to channel control registers drm/nouveau/disp: audit and version display classes drm/nouveau/disp: audit and version SCANOUTPOS method drm/nv50-/disp: audit and version PIOR_PWR method ...

| | | | | | | | | | | | | | | | No-one has yet had time to move this to debugfs as discussed during the last merge window. Until this happens, hide the option to make it clear it's not going to be here forever. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | ... 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>

| | | | | | | | | | | | | | | | | | 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>
| * drm/gf100-/gr: improve initial context patch list helpersBen Skeggs2014-08-104-20/+51

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | possible The indirect method has been left in-place here as a fallback path, as it may not be possible to map the non-PAGE_SIZE aligned control areas across some chipset+interface combinations. This isn't a problem for the primary use-case where the core and drm are linked together in kernel-land, but across a VM or (in the case where it applies now) between the core in the kernel and a userspace test tool.

In the future this will be extended to handle channels, replacing some long-unloved code we currently use, and allow fifo/display/mpeg (hi Ilia ;)) engines to all be exposed in the same way.
