drm/tegra: gr3d: Assert reset before power-gating

2020-07-17T14:06:15+00:00

Tegra TRM documentation states that hardware should be in a default state when power partition is turned off, i.e. reset should be asserted. This patch adds the missing reset assertions. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

gpu: host1x: Rename "parent" to "host"

2020-01-10T15:37:38+00:00

Rename the host1x clients' parent to "host" because that more closely describes what it is. The parent can be confused with the parent device in terms of the device hierarchy. Subsequent patches will add a new member that refers to the parent in that hierarchy. Signed-off-by: Thierry Reding

drm/tegra: Simplify IOMMU group selection

2019-10-29T14:04:34+00:00

All the devices that make up the DRM device are now part of the same IOMMU group. This simplifies the handling of the IOMMU attachment and also avoids exhausting the number of IOMMUs available on early Tegra SoC generations. Signed-off-by: Thierry Reding

drm/tegra: Move IOMMU group into host1x client

2019-10-28T10:18:37+00:00

Handling of the IOMMU group attachment is common to all clients, so move the group into the client to simplify code. Signed-off-by: Thierry Reding

gpu: host1x: Request channels for clients, not devices

2019-10-28T10:18:33+00:00

A struct device doesn't carry much information that a channel might be interested in, but the client very much does. Request channels for the clients rather than their parent devices and store a pointer to them in order to have that information available when needed. Signed-off-by: Thierry Reding

drm/tegra: gr3d: Track interface version

2018-05-18T20:00:25+00:00

Set the interface version implemented by the gr3d module. This allows userspace to pass the correct command stream when programming the gr3d module. Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: Refactor IOMMU attach/detach

2018-05-17T12:08:40+00:00

Attaching to and detaching from an IOMMU uses the same code sequence in every driver, so factor it out into separate helpers. Reviewed-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: gr3d: Properly clean up resources

2018-05-17T12:03:30+00:00

Failure to register the Tegra DRM client would leak the resources. Move cleanup code to error unwinding gotos to fix that and share the cleanup code with the other error paths. Reviewed-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: gr3d: Add IOMMU support

2018-05-04T12:20:09+00:00

Attach GR3D to the displays IOMMU group in order to provide GR3D access to BO's IOVA. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding
