Bisected guest kernel changes crashing qemu. Landed at "6c1cd97b drm/virtio: fix resource id handling". Looked again, and noticed we where not only leaking *some* ids, but *all* ids. The old code never ever called virtio_gpu_resource_id_put(). So, commit 6c1cd97b effectively makes the linux kernel starting re-using IDs after releasing them, and apparently virglrenderer can't deal with that. Oops. This patch puts a temporary stopgap into place for the 5.0 release. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by: -

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. Signed-off-by: -

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.

The LUTs are single buffered so we should program them after the double buffered pipe updates have been latched by the hardware. We'll also fix up the IPS vs. split gamma w/a to do the IPS disable like everyone else. Note that this is currently dead code as we don't use the split gamma mode on HSW, but that will be fixed up shortly. Signed-off-by:

Split the color management hooks along the single vs. double buffered registers line. Of the currently programmed registers GAMMA_MODE and the ilk+ pipe CSC are double buffered, the LUTS and CHV CGM block are single buffered. The double buffered register will be programmed during the normal pipe update with evasion, and also during pipe enable so that the settings will already be correct when the pipe starts up before the planes are enabled. The single buffered registers are currently programmed before the vblank evade. Which is totally wrong, but we'll correct that later. v2: Add some docs to explain the two vfuncs (Matt,Uma) Rebase Signed-off-by: -

Ville Syrjälä authored
On g4x+ the pipe gamma enable bit for the primary plane affects the pipe bottom color as well. The same for the pipe csc enable bit on ilk+. Thus we must configure those bits correctly even when the primary plane is disabled. To make the feasible let's split those settings from the plane_ctl() function into a seprate funciton that we can call from the ->disable_plane() hook as well. For consistency we'll do that on all the plane types. While that has no real benefits at this time, it'll become useful when we start to control the pipe gamma/csc enable bits dynamically when we overhaul the color management code. On pre-g4x there doesn't appear to be any way to gamma correct the pipe bottom color, but sticking to the same pattern doesn't hurt. And it'll still help us to do crtc state readout correctly for the pipe gamma enable bit for the color management overhaul. An alternative apporach would be to still precompute these bits into plane_state->ctl, but that would require that we run through the plane check even when the plane isn't logically enabled on any crtc. Currently that condition causes us to short circuit the entire thing and not call ->check_plane(). There would also be some chicken and egg problems with ->check_plane() vs. crtc color state check that would requite splitting certain things into multiple steps. So all in all this seems like the easier route. Signed-off-by:

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. Signed-off-by: -

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: -

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. Reviewed-by:

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.

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:

The host1x CDMA push buffer is terminated by a special opcode (RESTART) that tells the CDMA to wrap around to the beginning of the push buffer. To accomodate the RESTART opcode, an extra 4 bytes are allocated on top of the 512 * 8 = 4096 bytes needed for the 512 slots (1 slot = 2 words) that are used for other commands passed to CDMA. This requires that two memory pages are allocated, but most of the second page (4092 bytes) is never used. Decrease the number of slots to 511 so that the RESTART opcode fits within the page. Adjust the push buffer wraparound code to take into account push buffer sizes that are not a power of two. Signed-off-by: -

The HOST1X_CHANNEL_DMAEND is an offset relative to the value written to the HOST1X_CHANNEL_DMASTART register, but it is currently treated as an absolute address. This can cause SMMU faults if the CDMA fetches past a pushbuffer's IOMMU mapping. Properly setting the DMAEND prevents the CDMA from fetching beyond that address and avoid such issues. This is currently not observed because a whole (almost) page of essentially scratch space absorbs any excessive prefetching by CDMA. However, changing the number of slots in the push buffer can trigger these SMMU faults. Signed-off-by: -
