2020-02-06gpu: host1x: Set DMA direction only for DMA-mapped buffer objectsThierry Reding1-1/+1
The DMA direction is only used by the DMA API, so there is no use in setting it when a buffer object isn't mapped with the DMA API. Signed-off-by: Thierry Reding <treding@nvidia.com> Tested-by: Dmitry Osipenko <digetx@gmail.com> Reviewed-by: Dmitry Osipenko <digetx@gmail.com>
2020-02-06drm/tegra: Reuse IOVA mapping where possibleThierry Reding3-23/+63
This partially reverts the DMA API support that was recently merged because it was causing performance regressions on older Tegra devices. Unfortunately, the cache maintenance performed by dma_map_sg() and dma_unmap_sg() causes performance to drop by a factor of 10. The right solution for this would be to cache mappings for buffers per consumer device, but that's a bit involved. Instead, we simply revert to the old behaviour of sharing IOVA mappings when we know that devices can do so (i.e. they share the same IOMMU domain).

2020-02-06drm/tegra: Relax IOMMU usage criteria on old TegraThierry Reding1-17/+32
Older Tegra devices only allow addressing 32 bits of memory, so whether or not the host1x is attached to an IOMMU doesn't matter. host1x IOMMU attachment is only needed on devices that can address memory beyond the 32-bit boundary and where the host1x doesn't support the wide GATHER opcode that allows it to access buffers at higher addresses.

2020-01-31drm/tegra: sor: Initialize runtime PM before useThierry Reding1-15/+17
Commit fd67e9c6ed5a ("drm/tegra: Do not implement runtime PM") replaced the generic runtime PM usage by a host1x bus-specific implementation in order to work around some assumptions baked into runtime PM that are in conflict with the requirements in the Tegra DRM driver. Unfortunately the new runtime PM callbacks are not setup yet at the time when the SOR driver first needs to resume the device to register the SOR pad clock, and accesses to register will cause the system to hang. Note that this only happens on Tegra124 and Tegra210 because those are the only SoCs where the SOR pad clock is registered from the SOR driver. Later generations use a SOR pad clock provided by the BPMP. Fix this by moving the registration of the SOR pad clock after the host1x client has been registered. That's somewhat suboptimal because this could potentially, though it's very unlikely, cause the Tegra DRM to be probed if the SOR happens to be the last subdevice to register, only to be immediately removed again if the SOR pad output clock fails to register. That's just a minor annoyance, though, and doesn't justify implementing a workaround. Fixes: fd67e9c6ed5a ("drm/tegra: Do not implement runtime PM") Signed-off-by: Thierry Reding <treding@nvidia.com>

2020-01-29drm/nouveau: Add HD-audio component notifier supportTakashi Iwai3-0/+119
This patch adds the support for the notification of HD-audio hotplug via the already existing drm_audio_component framework. This allows us more reliable hotplug notification and ELD transfer without accessing HD-audio bus; it's more efficient, and more importantly, it works without waking up the runtime PM. The implementation is rather simplistic: nouveau driver provides the get_eld ops for HD-audio, and it notifies the audio hotplug via pin_eld_notify callback upon each nv50_audio_enable() and _disable() call. As the HD-audio pin assignment seems corresponding to the CRTC, the crtc->index number is passed directly as the zero-based port number. The bind and unbind callbacks handle the device-link so that it assures the PM call order.

The low-level Falcon bootstrapping callbacks are expected to return 0 on success or a negative error code on failure. However, the implementation on Tegra returns the ID or mask of the Falcons that were bootstrapped on success, thus breaking the calling code, which treats this as failure. Fix this by making sure we only return 0 or a negative error code, just like the code for discrete GPUs does.
