Pull drm updates from Dave Airlie: "This has two exciting community drivers for ARM Mali accelerators. Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging.

2019-04-18drm/tegra: gem: Fix CPU-cache maintenance for BO's allocated using get_pages()Dmitry Osipenko1-2/+2
The allocated pages need to be invalidated in CPU caches. On ARM32 the DMA_BIDIRECTIONAL flag only ensures that data is written-back to DRAM and the data stays in CPU cache lines. While the DMA_FROM_DEVICE flag ensures that the corresponding CPU cache lines are getting invalidated and nothing more, that's exactly what is needed for a newly allocated pages. This fixes randomly failing rendercheck tests on Tegra30 using the Opentegra driver for tests that use small-sized pixmaps (10x10 and less, i.e. 1-2 memory pages) because apparently CPU reads out stale data from caches and/or that data is getting evicted to DRAM at the time of HW job execution.

2019-02-07drm/tegra: vic: Support stream ID register programmingThierry Reding2-0/+30
The version of VIC found in Tegra186 and later incorporates improvements with regards to context isolation. As part of those improvements, stream ID registers were added that allow to specify separate stream IDs for the Falcon microcontroller and the VIC memory interface. While it is possible to also set the stream ID dynamically at runtime to allow userspace contexts to be completely separated, this commit doesn't implement that yet. Instead, the static VIC stream ID is programmed when the Falcon is booted. This ensures that memory accesses by the Falcon or the VIC are properly translated via the SMMU.

2019-02-07drm/tegra: Restrict IOVA space to DMA maskThierry Reding1-2/+3
On Tegra186 and later, the ARM SMMU provides an input address space that is 48 bits wide. However, memory clients can only address up to 40 bits. If the geometry is used as-is, allocations of IOVA space can end up in a region that cannot be addressed by the memory clients. To fix this, restrict the IOVA space to the DMA mask of the host1x device. Note that, technically, the IOVA space needs to be restricted to the intersection of the DMA masks for all clients that are attached to the IOMMU domain. In practice using the DMA mask of the host1x device is sufficient because all host1x clients share the same DMA mask. Signed-off-by: Thierry Reding <[email protected]>
2019-02-07drm/tegra: Setup shared IOMMU domain after initializationThierry Reding1-25/+29
Move initialization of the shared IOMMU domain after the host1x device has been initialized. At this point all the Tegra DRM clients have been attached to the shared IOMMU domain. This is important because Tegra186 and later use an ARM SMMU, for which the driver defers setting up the geometry for a domain until a device is attached to it. This is to ensure that the domain is properly set up for a specific ARM SMMU instance, which is unknown at allocation time.

2019-02-07drm/tegra: vic: Load firmware on demandThierry Reding1-17/+36
Loading the firmware requires an allocation of IOVA space to make sure that the VIC's Falcon microcontroller can read the firmware if address translation via the SMMU is enabled. However, the allocation currently happens at a time where the geometry of an IOMMU domain may not have been initialized yet. This happens for example on Tegra186 and later where an ARM SMMU is used. Domains which are created by the ARM SMMU driver postpone the geometry setup until a device is attached to the domain. This is because IOMMU domains aren't attached to a specific IOMMU instance at allocation time and hence the input address space, which defines the geometry, is not known yet. Work around this by postponing the firmware load until it is needed at the time where a channel is opened to the VIC. At this time the shared IOMMU domain's geometry has been properly initialized. As a byproduct this allows the Tegra DRM to be created in the absence of VIC firmware, since the VIC initialization no longer fails if the firmware can't be found.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter4-3/+4
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2018-12-06drm/tegra: sor: Reset the SOR if possibleThierry Reding1-4/+13
If the SOR is already up and running when the kernel driver is probed, setting a mode will typically fail. This can be seen for example on Jetson TX2. Under certain circumstances the generic power domain code will cause the SOR to be reset. However, if the power domain is never powered off (this can happen if the HDA controller is enabled, which is part of the same power domain as the SOR), then the SOR will end up not getting reset and fail to properly set a mode. To work around this, try to get the reset control and assert/deassert it, irrespective of whether or not a generic power domain is attached to the SOR. On platforms where the kernel implements generic power domains (up to Tegra210) this will fail, because the power domain will already have acquired an exclusive reference to the reset control. But on recent platforms there the BPMP provides an ABI to control power domains, it's possible to acquire the reset control from SOR and use it to put the SOR into a known good state at probe time. The proper solution for this is to make the SOR driver capable of dealing with hardware that's already up and running (by first grace- fully shutting it down, or perhaps by seamlessly transitioning to the kernel driver and taking over the running display configuration). That is fairly involved, though, so we'll go with this quickfix for now. Signed-off-by: Thierry Reding <[email protected]>

If generic PM domains are not implemented, such as on 32-bit Tegra, the resets need to be asserted and deasserted explicitly by the driver.

2018-09-26drm/tegra: Detach devices from IOMMU DMA domain on arm32Dmitry Osipenko1-0/+12
All Tegra DRM devices are getting attached to an implicit IOMMU DMA domain if CONFIG_ARM_DMA_USE_IOMMU=y. Since Tegra DRM driver manages IOMMU by itself, the devices must be detached from the implicit domain using arch-specific IOMMU-API. Note that this works only for arm32 and not for arm64, which will remain broken if CONFIG_IOMMU_DMA is enabled.

2018-09-26drm/tegra: Replace drm_dev_unref with drm_dev_putThomas Zimmermann1-5/+5
This patch unifies the naming of DRM functions for reference counting of struct drm_device. The resulting code is more aligned with the rest of the Linux kernel interfaces.

2018-09-26drm/tegra: sor: Add Tegra194 supportThierry Reding2-0/+111
The SOR implemented in Tegra194 is subtly different from its predecessor found in Tegra186. Most notably some registers have been moved around so it is no longer compatible. Signed-off-by: Thierry Reding <[email protected]>

2018-09-26drm/tegra: hub: Add Tegra194 supportThierry Reding3-4/+17
The display hub integrated into Tegra194 is almost identical to the one found on Tegra186. However, it doesn't support DSC (display stream compression) so it isn't fully compatible. Signed-off-by: Thierry Reding <[email protected]>
2018-09-26drm/tegra: dc: Do not register DC without primary planeThierry Reding1-0/+22
Tegra194 contains a fourth display controller that does not own any windows. Therefore, we cannot currently assign a primary plane to it which causes KMS to eventually crash. Do not register the display controller if it owns no windows to work around this. Note that we still have to enable and probe the display controller because for some reason all display controllers need to be powered (and/or clocked) before any registers can be accessed in any of the display controllers.

2018-09-18drm/tegra: Convert drm_atomic_helper_suspend/resume()Souptick Joarder3-45/+3
convert drm_atomic_helper_suspend/resume() to use drm_mode_config_helper_suspend/resume(). With this conversion, tegra_drm_fb_suspend() and tegra_drm_fb_resume() will not be used anymore. Both of these functions can be removed. Also, in tegra_drm struct's member state will not be used anymore. So this can be removed forever. Fixed one sparse warning.
