* drm/nouveau/disp/mcp7x: disable dptmds workaroundBen Skeggs2017-04-21
| | | | | | | | | | | | | commit 7dfee6827780d4228148263545af936d0cae8930 upstream. The workaround appears to cause regressions on these boards, and from inspection of RM traces, NVIDIA don't appear to do it on them either.

* drm/nouveau/mmu/nv4a: use nv04 mmu rather than the nv44 oneIlia Mirkin2017-04-21
| | | | | | | | | | | | | | | | | | | | | commit f94773b9f5ecd1df7c88c2e921924dd41d2020cc upstream. The NV4A (aka NV44A) is an oddity in the family. It only comes in AGP and PCI varieties, rather than a core PCIE chip with a bridge for AGP/PCI as necessary. As a result, it appears that the MMU is also non-functional. For AGP cards, the vast majority of the NV4A lineup, this worked out since we force AGP cards to use the nv04 mmu. However for PCI variants, this did not work. Switching to the NV04 MMU makes it work like a charm. Thanks to mwk for the suggestion. This should be a no-op for NV4A AGP boards, as they were using it already.

* drm/nouveau/fifo/gf100-: protect channel preempt with subdev mutexBen Skeggs2017-01-09
| | | | | | | | | | | | | | | commit b27add13f500469127afdf011dbcc9c649e16e54 upstream. This avoids an issue that occurs when we're attempting to preempt multiple channels simultaneously. HW seems to ignore preempt requests while it's still processing a previous one, which, well, makes sense. Fixes random "fifo: SCHED_ERROR 0d []" + GPCCS page faults during parallel piglit runs on (at least) GM107.

| | | | | | | | | | | | | commit 5b3800a6b763874e4a23702fb9628d3bd3315ce9 upstream. DPAUX registers moved on Kepler, these chipsets were still using the Fermi implementation for some reason. This fixes detection of hotplug/sink IRQs on DP connectors. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* drm/nouveau/gr: fallback to legacy paths during firmware lookupAlexandre Courbot2017-01-09
| | | | | | | | | | | | | | | | | | commit e137040e0d0376b404fc5155eba44ea07126e3bd upstream. Look for firmware files using the legacy ("nouveau/nvxx_fucxxxx") path if they cannot be found in the new, "official" path. User setups were broken by the switch, which is bad. There are only 4 firmware files we may want to look up that way, so hardcode them into the lookup function. All new firmware files should use the standard "nvidia/<chip>/gr/" path.

* drm/nouveau: Revert "bus: remove cpu_coherent flag"Karol Herbst2016-09-22
| | | | | | | | | | | | | This reverts commit aff51175cdbf345740ec9203eff88e772af88059. The commit caused fence timeouts within nvc0_screen_destroy and most likely other places as well. The most obvious effect is, that userspace processes take minutes to actually quit. Signed-off-by: Karol Herbst <karolherbst@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* | drm/nouveau/bus: remove cpu_coherent flagAlexandre Courbot2016-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This flag's only remaining function is to ignore the uncached flag for BOs on coherent architectures. However the reason for allocating an object uncache on a non-coherent architecture (namely because the cost of doing explicit flushes/ invalidations is higher than the benefit of caching the data because accesses are few and far between) should also apply on architectures for which coherency is maintained implicitly. Thus allocate coherent objects as uncached on all architectures. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
