2025-03-07iommufd: Fail replace if device has not been attachedYi Liu
The current implementation of iommufd_device_do_replace() implicitly assumes that the input device has already been attached. However, there is no explicit check to verify this assumption. If another device within the same group has been attached, the replace operation might succeed, but the input device itself may not have been attached yet. As a result, the input device might not be tracked in the igroup->device_list, and its reserved IOVA might not be added. Despite this, the caller might incorrectly assume that the device has been successfully replaced, which could lead to unexpected behavior or errors. To address this issue, add a check to ensure that the input device has been attached before proceeding with the replace operation. This check will help maintain the integrity of the device tracking system and prevent potential issues arising from incorrect assumptions about the device's attachment status.

2025-03-07drm/amd: Keep display off while going into S4Mario Limonciello
When userspace invokes S4 the flow is: 1) amdgpu_pmops_prepare() 2) amdgpu_pmops_freeze() 3) Create hibernation image 4) amdgpu_pmops_thaw() 5) Write out image to disk 6) Turn off system Then on resume amdgpu_pmops_restore() is called. This flow has a problem that because amdgpu_pmops_thaw() is called it will call amdgpu_device_resume() which will resume all of the GPU. This includes turning the display hardware back on and discovering connectors again. This is an unexpected experience for the display to turn back on. Adjust the flow so that during the S4 sequence display hardware is not turned back on.

2025-03-07Bluetooth: btusb: Configure altsetting for HCI_USER_CHANNELHsin-chen Chuang
Automatically configure the altsetting for HCI_USER_CHANNEL when a SCO is connected. The motivation is to enable the HCI_USER_CHANNEL user to send out SCO data through USB Bluetooth chips, which is mainly used for bidirectional audio transfer (voice call). This was not capable because: - Per Bluetooth Core Spec v5, Vol 4, Part B, 2.1, the corresponding alternate setting should be set based on the air mode in order to transfer SCO data, but - The Linux Bluetooth HCI_USER_CHANNEL exposes the Bluetooth Host Controller Interface to the user space, which is something above the USB layer. The user space is not able to configure the USB alt while keeping the channel open. This patch intercepts the HCI_EV_SYNC_CONN_COMPLETE packets in btusb, extracts the air mode, and configures the alt setting in btusb. This patch is tested on ChromeOS devices. The USB Bluetooth models (CVSD, TRANS alt3 and alt6) could work without a customized kernel.

Add skl_wm_plane_disable_noatomic() which will clear out all the ddb and wm state for the plane. And let's do this _before_ we call plane->disable_arm() so that it'll actually clear out the state in the hardware as well. Currently this won't do anything new for most of the intel_plane_disable_noatomic() calls since those are done before wm readout, and thus everything wm/ddb related in the state will still be zeroed anyway. The only difference will be for skl_dbuf_sanitize() is happens after wm readout. But I'll be reordering thigns so that wm readout happens earlier and at that point this will guarantee that we still clear out the old wm/ddb junk from the state.

2025-03-07drm/i915: clean up pipe's ddb usage in intel_crtc_disable_noatomic()Ville Syrjälä
Update the ddb tracking information when we disable a pipe during sanitization. Avoids leaving stale junk in the states. Currently this doesn't do anything as we haven't read out this state yet when we do the sanitization, but that will change soon.

2025-03-07drm/i915: Extract skl_wm_crtc_disable_noatomic()Ville Syrjälä
Hoist the dbuf stuff into a separate function from intel_crtc_disable_noatomic_complete() so that the details are better hidden inside skl_watermark.c. We can also skip the whole thing on pre-skl since the dbuf state isn't actually used on those platforms. The readout path does still fill dbuf_state->active_pipes but we'll remedy that later.

2025-03-07drm/i915: Don't clobber crtc_state->cpu_transcoder for inactive crtcsVille Syrjälä
Inactive crtcs are supposed to have their crtc_state completely cleared. Currently we are clobbering crtc_state->cpu_transcoder before determining whether it's actually enabled or not. Don't do that. I want to rework the inherited flag handling for inactive crtcs a bit, and having a bogus cpu_transcoder in the crtc state can then cause confusing fastset mismatches even when the crtc never changes state during the commit.
