2016-11-07drm/nouveau/kms: execute drm_mode_config_reset() after constructing displayBen Skeggs1-0/+2
This will ensure we have some kind of initial atomic state for all objects after initialisation. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-07drm/nouveau/kms: move drm_crtc_force_disable_all() earlierBen Skeggs3-5/+7
nouveau_display_fini() is responsible for quiescing the hardware, so this is where such actions belong. More than that, nouveau_display_fini() switches off the receiving of sink irqs, which MST will require while shutting down an active head. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-07drm/nouveau/kms: drop dpms off/on in response to hotplugBen Skeggs1-8/+0
This primarily existed to ensure the DP link got retrained, and is now unnecessary as that's handled by NVKM already. For anything beyond that, we send an event to userspace and let it decide on an appropriate action to take. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-11-07drm/nouveau/tegra: Fix error handlingChristophe JAILLET1-1/+1
'iommu_domain_alloc()' returns NULL in case of error, not an error pointer. So test it accordingly. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Reviewed-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-07drm/nouveau/fb: add gm20b deviceAlexandre Courbot6-2/+48
gm20b's FB has the same capabilities as gm200, minus the ability to allocate RAM. Create a device that reflects this instead of re-using the gk20a device which may be incorrect.

2016-11-07drm/nouveau/fb/gk20a: use regular gf100's functionsAlexandre Courbot1-12/+5
gk20a's FB is not special compared to other Kepler chips, besides the fact it does not have VRAM. Use the regular gf100 hooks instead of the incomplete versions we rewrote.

2016-11-07drm/nouveau/fb/gk20a: fix constructor callAlexandre Courbot1-1/+2
The gf100 constructor should be called, otherwise we will allocate a smaller object than expected. This was without effect so far because gk20a did not allocate a page, but with gf100's page allocation moved to the oneinit() hook this problem has become apparent.

2016-11-07drm/nouveau/pmu: remove reset() hookAlexandre Courbot2-11/+0
The reset hook of pmu_func is never called, and gt215 was the only chip to implement. Remove this dead code. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-07drm/nouveau: fix notify data leakLucas Stach1-4/+2
There is no reason to not free the notify data if the NTFY_DEL ioctl failed. As nvif_notify_fini() is also called from the cleanup path of nvif_notify_init(), the notifier may not have been successfully created at that point. But it should also be the right thing to just free the data in the regular fini calls, as there is nothing much we can do if the ioctl fails, so better not leak memory.

2016-11-07drm/nouveau: fix nv84 fence context leakLucas Stach1-1/+1
uevent based fences hold a reference to the fence context, just like the legacy ones. So they need to drop this reference in the same way. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-07drm/nouveau: hide gcc-4.9 -Wmaybe-uninitializedArnd Bergmann1-1/+1
gcc-4.9 notices that the validate_init() function returns unintialized data when called with a zero 'nr_buffers' argument, when called with the -Wmaybe-uninitialized flag: drivers/gpu/drm/nouveau/nouveau_gem.c: In function ‘validate_init.isra.6’: drivers/gpu/drm/nouveau/nouveau_gem.c:457:5: error: ‘ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized] However, the only caller of this function always passes a nonzero argument, and gcc-6 is clever enough to take this into account and not warn about it any more. Adding an explicit initialization to -EINVAL here is correct even if the caller changed, and it avoids the warning on gcc-4.9 as well.

2016-11-07drm/nouveau/i2c/aux/g94-: retry transactions after hw reports an errorBen Skeggs2-10/+10
This fixes (works around?) link training failures seen on (at least) the Lenovo P50's internal panel. It's also an important fix on the same system for MST support on the dock. Sometimes, right after receiving an IRQ from the sink, there's an error bit (SINKSTAT_ERR) set in the DPAUX registers before we've even attempted a transaction. v2.
