2019-02-11Merge tag 'drm/tegra/for-5.1-rc1' of ↵Dave Airlie10-235/+285
git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v5.1-rc1 This set of changes starts of with some refactoring of the CEC support to make it reusable on Tegra210 and later. Following are a couple of fixes for HDMI audio support (via HDA). The bulk here is a set of preparatory patches working towards enabling Tegra186 support for host1x and VIC. Additional patches will be needed to fully enable this, but they're not quite ready yet. To round things off, this also adds support for configuring the SOR crossbar using device tree, and fixes a couple of job-related issues in the host1x code.

2019-02-08drm: rcar-du: Turn LVDS clock output on/off for DPAD0 output on D3/E3Laurent Pinchart3-0/+38
On the D3 and E3 SoCs the LVDS PLL clock output provides the dot clock to the DU channels, even when the LVDS outputs are not in use. Enable and disable the LVDS clock output when enabling or disabling a CRTC connected to the DPAD0 output. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2019-02-08drm: rcar-du: lvds: Add API to enable/disable clock outputLaurent Pinchart4-11/+96
On the D3 and E3 platforms, the LVDS internal PLL supplies the pixel clock to the DU. This works automatically for LVDS outputs as the LVDS encoder is enabled through the bridge API, enabling the internal PLL and clock output. However, when using the DU DPAD output with the LVDS outputs turned off, the LVDS PLL needs to be controlled manually. Add an API to do so, to be called by the DU driver. The drivers/gpu/drm/rcar-du/ directory has to be treated as obj-y unconditionally, as the LVDS driver could be built-in while the DU driver is compiled as a module.

2019-02-08drm: rcar-du: lvds: Don't fail probe if output is not connected on D3/E3Laurent Pinchart1-2/+15
On the D3 and E3 SoCs the LVDS encoder has an extended internal PLL and supplies a clock to the DU. That clock is used not only for the LVDS outputs but also for the DPAD output. The LVDS encoder thus needs to be available to the DU even when its output is disabled. Don't fail probe in that case on D3 and E3.

2019-02-08drm: rcar-du: Simplify encoder registrationLaurent Pinchart3-52/+6
Before the driver fully moved to drm_bridge and drm_panel, it was necessary to parse DT and locate encoder and connector nodes. The connector node is now unused and can be removed as a parameter to rcar_du_encoder_init(). As a consequence rcar_du_encoders_init_one() can be greatly simplified, removing most of the DT parsing.

2019-02-07drm/tegra: sor: Support device tree crossbar configurationThierry Reding1-2/+17
The crossbar configuration is usually the same across all designs for a given SoC generation. But sometimes there are designs that require some other configuration. Implement support for parsing the crossbar configuration from a device tree. If the crossbar configuration is not present in the device tree, fall back to the default crossbar configuration.

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: vic: Do not clear driver dataThierry Reding1-1/+0
Upon driver failure, the driver core will take care of clearing the driver data, so there's no need to do so explicitly in the driver. Reviewed-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
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 <treding@nvidia.com>
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.

2019-02-07drm/tegra: Store parent pointer in Tegra DRM clientsThierry Reding2-0/+3
Tegra DRM clients need access to their parent, so store a pointer to it upon registration. It's technically possible to get at this by going via the host1x client's parent and getting the driver data, but that's quite complicated and not very transparent. It's much more straightforward and natural to let the children know about their parent. Signed-off-by: Thierry Reding <treding@nvidia.com> Reviewed-by: Dmitry Osipenko <digetx@gmail.com>

2019-02-01drm/i915: Enable fastboot by default on VLV and CHVHans de Goede1-1/+9
We really want to have fastboot enabled by default to avoid an ugly modeset during boot. Currently we are enabling fastboot by default on gen9+ (Skylake and newer). The intention is to enable it on older generations after it has seen more testing on gen9+. VLV and CHV devices are still being sold in stores today, as such it is desirable to also enable fastboot by default on these now. I've extensively tested fastboot=1 support on over 50 different Bay- and Cherry-Trail devices. Testing DSI and eDP panels as well as HDMI output (and even DP over Type-C on one device). All 50 devices work fine with fastboot=1. On 2 devices their DSI panel turns black as soon as the i915 driver loads when fastboot=0, so having fastboot enabled is required for these 2 to work properly (for lack of a better fix).

We can't safely probe Type C ports, whether they are a legacy or a USB/Thunderbolt DP Alternate Type C port. This would require performing the TypeC connect sequence - as described by the specification - but that may have unwanted side-effects. These side-effects include at least - without completeness - timeouts during AUX power well enabling and subsequent PLL enabling errors. To safely identify these ports we really need VBT, which has the proper flag for this (ddi_vbt_port_info::supports_typec_usb, supports_tbt). Based on the above disable Type C ports if we can't load VBT for some reason. v2: - Notice that we disable TypeC ports completely and simplify accordingly (Jose). - Add code comment explaining why we disabled the ports.

commit 5b0bd14dcc6b ("drm/i915/icl: keep track of unused pll while looping") inadvertently (I presume) changed the code to pick the last unused dpll rather than the first unused one like we did before. While there should most likely be no harm in changing the order let's change back just to avoid a change in the behaviour. At least it might reduce the confusion when staring at logs (took me a while to figure out why DPLL1 being picked over DPLL0 when the latter was most definitely available).

2019-01-30drm/i915: Apply LUT validation checks to platforms more accurately (v3)Matt Roper3-32/+40
Use of the new DRM_COLOR_LUT_NON_DECREASING test was a bit over-zealous; it doesn't actually need to be applied to the degamma on "bdw-style" platforms. Likewise, we overlooked the fact that CHV should have that test applied to the gamma LUT as well as the degamma LUT. Rather than adding more complicated platform checking to intel_color_check(), let's just store the appropriate set of LUT validation flags for each platform in the intel_device_info structure. v2: - Shuffle around LUT size tests so that the hardware-specific tests won't be applied to legacy gamma tables. (Ville) - Add a debug message so that it will be easier to understand why an atomic transaction involving incorrectly-sized LUT's got rejected by the driver. v3: - Switch size_t's to int's. (Ville) Fixes: 85e2d61e4976 ("drm/i915: Validate userspace-provided color management LUT's (v4)") References: https://lists.freedesktop.org/archives/intel-gfx/2019-January/187634.html Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190130181022.4291-1-matthew.d.roper@intel.com
2019-01-30drm/i915: Force background color to black for gen9+ (v2)Matt Roper2-0/+25
We don't yet allow userspace to control the CRTC background color, but we should manually program the color to black to ensure the BIOS didn't leave us with some other color. We should also set the pipe gamma and pipe CSC bits so that the background color goes through the same color management transformations that a plane with black pixels would. v2: Rename register to SKL_BOTTOM_COLOR to more closely follow bspec naming.
