drm/tegra: Consolidate runtime PM management of older UAPI codepath

2021-12-16T13:07:08+00:00

Move runtime PM management of older UAPI code paths into the common place. This removes boilerplate code from client drivers. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

gpu: host1x: Cleanup and refcounting for syncpoints

2021-03-31T15:42:13+00:00

Add reference counting for allocated syncpoints to allow keeping them allocated while jobs are referencing them. Additionally, clean up various places using syncpoint IDs to use host1x_syncpt pointers instead. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

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
