2025-06-29Rewrite of propagate_umount()Al Viro
The variant currently in the tree has problems; trying to prove correctness has caught at least one class of bugs (reparenting that ends up moving the visible location of reparented mount, due to not excluding some of the counterparts on propagation that should've been included). I tried to prove that it's the only bug there; I'm still not sure whether it is. If anyone can reconstruct and write down an analysis of the mainline implementation, I'll gladly review it; as it is, I ended up doing a different implementation. Candidate collection phase is similar, but trimming the set down until it satisfies the constraints turned out pretty different. I hoped to do transformation as a massage series, but that turns out to be too convoluted. So it's a single patch replacing propagate_umount() and friends in one go, with notes and analysis in D/f/propagate_umount.txt (in addition to inline comments). As far I can tell, it is provably correct and provably linear by the number of mounts we need to look at in order to decide what should be unmounted. It even builds and seems to survive testing... Another nice thing that fell out of that is that ->mnt_umounting is no longer needed. Compared to the first version: * explicit MNT_UMOUNT_CANDIDATE flag for is_candidate() * trim_ancestors() only clears that flag, leaving the suckers on list * trim_one() and handle_locked() take the stuff with flag cleared off the list. That allows to iterate with list_for_each_entry_safe() when calling trim_one() - it removes at most one element from the list now. * no globals - I didn't bother with any kind of context, not worth it. * Notes updated accordingly; I have not touch the terms yet.

2025-06-27dt-bindings: dsa: Rewrite Micrel KS8995 in schemaLinus Walleij
After studying the datasheets for some of the KS8995 variants it becomes pretty obvious that this is a straight-forward and simple MII DSA switch with one port in (CPU) and four outgoing ports, and it even supports custom tags by setting a bit in a special register, and elaborate VLAN handling as all DSA switches do. What is a bit odd with KS8995 is that it uses an extra MII-P5 port to access one of the PHYs separately, on the side of the switch fabric, such as when using a WAN port separately from a LAN switch in a home router. Rewrite the terse bindings to YAML, and move to the proper subdirectory. Include a verbose example to make things clear.

2025-06-27drm/i915/flipq: Provide the nuts and bolts code for flip queueVille Syrjälä
Provide the lower level code for PIPEDMC based flip queue. We'll use the so called semi-full flip queue mode where the PIPEDMC will start the provided DSB on a scanline a little ahead of the vblank. We need to program the triggering scanline early enough so that the DSB has enough time to complete writing all the double buffered registers before they get latched (at start of vblank). The firmware implements several queues: - 3 "plane queues" which execute a single DSB per entry - 1 "general queue" which can apparently execute 2 DSBs per entry - 1 vestigial "fast queue" that replaced the "simple flip queue" on ADL+, but this isn't supposed to be used due to issues. But we only need a single plane queue really, and we won't actually use it as a real queue because we don't allow queueing multiple commits ahead of time. So the whole thing is perhaps useless. I suppose there migth be some power saving benefits if we would get the flip scheduled by userspace early and then could keep some hardware powered off a bit longer until the DMC kicks off the flipq programming. But that is pure speculation at this time and needs to be proven. The code to hook up the flip queue into the actual atomic commit path will follow later. TODO: need to think how to do the "wait for DMC firmware load" nicely need to think about VRR and PSR etc. v2: Don't write DMC_FQ_W2_PTS_CFG_SEL on pre-lnl Don't oops at flipq init if there is no dmc v3: Adapt to PTL+ flipq changes (different queue entry layout, different trigger event, need VRR TG) Use the actual CDCLK frequency Ask the DSB code how long things are expected to take v3: Adjust the cdclk rounding (docs are 100% vague, Windows rounds like this) Initialize some undocumented magic DMC variables on PTL v4: Use PIPEDMC_FQ_STATUS for busy check (the busy bit in PIPEDMC_FQ_CTRL is apparently gone on LNL+) Based the preempt timeout on the max exec time Preempt before disabling the flip queue Order the PIPEDMC_SCANLINECMP* writes a bit more carefully Fix some typos v5: Try to deal with some clang-20 div-by-zero false positive (Nathan) Add some docs (Jani) Cc: Nathan Chancellor <nathan@kernel.org> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> epr Link: https://patchwork.freedesktop.org/patch/msgid/20250624170049.27284-5-ville.syrjala@linux.intel.com

In addition to GPIO synchronization, The AD7768-1 also supports synchronization over SPI, which use is recommended when the GPIO cannot provide a pulse synchronous with the base MCLK signal. It consists of looping back the SYNC_OUT to the SYNC_IN pin and send a command via SPI to trigger the synchronization. Introduce the 'trigger-sources' property to enable SPI-based synchronization via SYNC_OUT pin, along with additional optional entries for GPIO3 and DRDY pins.

2025-06-26drm/gpusvm, drm/pagemap: Move migration functionality to drm_pagemapMatthew Brost
The migration functionality and track-keeping of per-pagemap VRAM mapped to the CPU mm is not per GPU_vm, but rather per pagemap. This is also reflected by the functions not needing the drm_gpusvm structures. So move to drm_pagemap. With this, drm_gpusvm shouldn't really access the page zone-device-data since its meaning is internal to drm_pagemap. Currently it's used to reject mapping ranges backed by multiple drm_pagemap allocations. For now, make the zone-device-data a void pointer. Alter the interface of drm_gpusvm_migrate_to_devmem() to ensure we don't pass a gpusvm pointer. Rename CONFIG_DRM_XE_DEVMEM_MIRROR to CONFIG_DRM_XE_PAGEMAP. Matt is listed as author of this commit since he wrote most of the code, and it makes sense to retain his git authorship. Thomas mostly moved the code around. v3: - Kerneldoc fixes (CI) - Don't update documentation about how the drm_pagemap migration should be interpreted until upcoming patches where the functionality is implemented.

2025-06-26checkpatch: check for comment explaining rgmii(|-rxid|-txid) PHY modesMatthias Schiffer
Historically, the RGMII PHY modes specified in Device Trees have been used inconsistently, often referring to the usage of delays on the PHY side rather than describing the board; many drivers still implement this incorrectly. Require a comment in Devices Trees using these modes (usually mentioning that the delay is realized on the PCB), so we can avoid adding more incorrect uses (or will at least notice which drivers still need to be fixed).

2025-06-26dt-bindings: display: ti: Add schema for AM625 OLDI TransmitterAradhya Bhatia
The OLDI transmitters (TXes) do not have registers of their own, and are dependent on the source video-ports (VPs) from the DSS to provide configuration data. This hardware doesn't directly sit on the internal bus of the SoC, but does so via the DSS. Hence, the OLDI TXes are supposed to be child nodes under the DSS, and not independent devices. Two of the OLDI TXes can function in tandem to output dual-link OLDI output, or cloned single-link outputs. In these cases, one OLDI will be the primary OLDI, and the other one, a companion. The following diagram represents such a configuration. +-----+-----+ +-------+ | | | | | | | VP1 +----+--->+ OLDI0 | (Primary - may need companion) | | | | | | | DSS +-----+ | +-------+ | | | | | | VP2 | | +-------+ | | | | | | +-----+-----+ +--->+ OLDI1 | (Companion OLDI) | | +-------+ The DSS in AM625 SoC has a configuration like the one above. The AM625 DSS VP1 (port@0) can connect and control 2 OLDI TXes, to use them in dual-link or cloned single-link OLDI modes. It is only the VP1 that can connect to either OLDI TXes for the AM625 DSS, and not the VP2. Alternatively, on some future TI SoCs, along with the above configuration, the OLDI TX can _also_ connect to separate video sources, making them work entirely independent of each other. In this case, neither of the OLDIs are "companion" or "secondary" OLDIs, and nor do they require one. They both are independent and primary OLDIs. The following diagram represents such a configuration. +-----+-----+ +-------+ | | | | | | | VP1 +--+----------->+ OLDI0 | (Primary - may need companion) | | | | | | | +-----+ | +-------+ | | | | | | VP2 | | | | | | | DSS +-----+ | +---+ +-------+ | | | +-->+ M | | | | | VP3 +----->+ U +--->+ OLDI1 | (Companion or Primary) | | | | X | | | | +-----+ +---+ +-------+ | | | | | VP4 | | | | +-----+-----+ Note that depending on the mux configuration, the OLDIs can either be working together in tandem - sourced by VP1, OR, they could be working independently sourced by VP1 and VP3 respectively. The idea is to support all the configurations with this OLDI TX schema. The OLDI functionality is further supported by a system-control module, which contains a few registers to control OLDI IO power and other electrical characteristics of the IO lanes. Add devicetree binding schema for the OLDI TXes to support various configurations, and extend their support to the AM625 DSS.
