Not needed as the device is in gfxoff state so the CG/PG state is handled just like it would be for gfxoff during runtime gfxoff. This should also prevent delays on resume. Reworked from Pratik's original patch (Alex) Acked-by:

Provide and explanation as to why we skip GFX and PSP for S0ix. GFX goes into gfxoff, same as runtime, so no need to tear down and re-init. PSP is part of the always on state, so no need to touch it. Acked-by:

This really needs to be done to properly tear down the device. SMC, PSP, and GFX are still problematic, need to dig deeper into what aspect of them that is problematic. Acked-by:

Once the device has runtime suspended, we don't need to power it back up again for system suspend. Likewise for resume, we don't to power up the device again on resume only to power it back off again via runtime pm because it's still idle. v2: add DPM_FLAG_SMART_PREPARE as well Reviewed-by:
-
Alex Deucher authored
as per: https://www.kernel.org/doc/html/latest/driver-api/pm/devices.html The prepare callback is required to support the DPM_FLAG_SMART_SUSPEND driver flag. This allows runtime pm to auto complete when the system goes into suspend avoiding a wake up on suspend and on resume. Apply this for hybrid gfx and BOCO systems where d3cold is provided by the ACPI platform. v2: check if device is runtime suspended in prepare. Reviewed-by:

Checkpatch was complaining about this - there's no need for us to print errors when kzalloc() fails, as kzalloc() will already WARN for us. So, let's fix that before converting things to make checkpatch happy. Signed-off-by:

Since we're about to move drm_dp_helper.c over to drm_dbg_*(), we'll want to make sure that we can also add ratelimited versions of these macros in order to retain some of the previous debugging output behavior we had. However, as I was preparing to do this I noticed that the current rate limited macros we have are kind of bogus. It looks like when I wrote these, I didn't notice that we'd always be calling __ratelimit() even if the debugging message we'd be printing would normally be filtered out due to the relevant DRM debugging category being disabled. So, let's fix this by making sure to check drm_debug_enabled() in our ratelimited macros before calling __ratelimit(), and start using drm_dev_printk() in order to print debugging messages since that will save us from doing a redundant drm_debug_enabled() check. And while we're at it, let's move the code for this into another macro that we can reuse for defining new ratelimited DRM debug macros more easily. v2: * Make sure to use tabs where possible in __DRM_DEFINE_DBG_RATELIMITED() Signed-off-by:

As pointed out by the documentation for drm_dp_aux_register(), drm_dp_aux_init() should be used in situations where the AUX channel for a display driver can potentially be registered before it's respective DRM driver. This is the case with Tegra, since the DP aux channel exists as a platform device instead of being a grandchild of the DRM device. Since we're about to add a backpointer to a DP AUX channel's respective DRM device, let's fix this so that we don't potentially allow userspace to use the AUX channel before we've associated it with it's DRM connector.

Allocate a new private stub fence in drm_syncobj_assign_null_handle, instead of using a static stub fence. When userspace creates a fence with DRM_SYNCOBJ_CREATE_SIGNALED or when userspace signals a fence via DRM_IOCTL_SYNCOBJ_SIGNAL, the timestamp obtained when the fence is exported and queried with SYNC_IOC_FILE_INFO should match when the fence's status was changed from the perspective of userspace, which is during the respective ioctl. When a static stub fence started being used in by these ioctls, this behavior changed. Instead, the timestamp returned by SYNC_IOC_FILE_INFO became the first time anything used the static stub fence, which has no meaning to userspace. Signed-off-by:
