We can directly calculate sdma doorbell indexes in the process doorbell pages through the doorbell_index structure in amdgpu_device, so no need to cache them in kgd2kfd_shared_resources any more. This alleviates the adaptation needs when new SDMA configurations are introduced. Signed-off-by:

Given a master fd we can then override the priority of the context in another fd. Using these overrides was recommended by Christian instead of trying to submit from a master fd, and I am adding a way to override a single context instead of the entire process so we can only upgrade a single Vulkan queue and not effectively the entire process. Reused the flags field as it was checked to be 0 anyways, so nothing used it. This is source-incompatible (due to the name change), but ABI compatible. Signed-off-by:

I don't see another way to figure out if a ring is initialized if the hardware block might not be initialized. Entities have been fixed up to handle num_rqs = 0. Signed-off-by:

Bas Nieuwenhuizen authored
Some blocks in amdgpu can have 0 rqs. Job creation already fails with -ENOENT when entity->rq is NULL, so jobs cannot be pushed. Without a rq there is no scheduler to pop jobs, and rq selection already does the right thing with a list of length 0. So the operations we need to fix are: - Creation, do not set rq to rq_list[0] if the list can have length 0. - Do not flush any jobs when there is no rq. - On entity destruction handle the rq = NULL case. - on set_priority, do not try to change the rq if it is NULL.

This prevents us from accessing extended registers in tools like umr. The register access functions already check if the offset is beyond the BAR size and use the indirect accessors with locking so this is safe. Reviewed-by:

CP_RB_DOORBELL_RANGE_LOWER/UPPER and CP_MEC_DOORBELL_RANGE_LOWER/UPPER are used for waking up an idle scheduler and for power gating support. Usually the first few doorbells in pci doorbell bar are used for RB and all leftover for MEC. This patch fixes the incorrect settings. Theoretically, gfx ring doorbells should come before all MEC doorbells to be consistent with the design. However, since the doorbell allocations are agreed by all and we are not free to change them, also considering the kernel MEC ring doorbells which are before gfx ring doorbells are not used often, we compromise by leaving the doorbell allocations unchanged.

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 SoCs the LVDS PLL clock output provides the dot clock to the DU channels, even when the LVDS outputs are not in use.

Laurent Pinchart authored
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.
