2025-09-08dt-bindings: ipmi: aspeed,ast2400-kcs-bmc: Add missing "clocks" propertyRob Herring (Arm)
The ASpeed kcs-bmc nodes have a "clocks" property which isn't documented. It looks like all the LPC child devices have the same clock source and some of the drivers manage their clock. Perhaps it is the parent device that should have the clock, but it's too late for that.

2025-09-08ipmi: Rework user message limit handlingCorey Minyard
The limit on the number of user messages had a number of issues, improper counting in some cases and a use after free. Restructure how this is all done to handle more in the receive message allocation routine, so all refcouting and user message limit counts are done in that routine. It's a lot cleaner and safer.

2025-09-08Revert "ipmi: fix msg stack when IPMI is disconnected"Corey Minyard
This reverts commit c608966f3f9c2dca596967501d00753282b395fc. This patch has a subtle bug that can cause the IPMI driver to go into an infinite loop if the BMC misbehaves in a certain way.

2025-09-08ipmi:msghandler:Change seq_lock to a mutexCorey Minyard
Dan Carpenter got a Smatch warning: drivers/char/ipmi/ipmi_msghandler.c:5265 ipmi_free_recv_msg() warn: sleeping in atomic context due to the recent rework of the IPMI driver's locking. I didn't realize vfree could block. But there is an easy solution to this, now that almost everything in the message handler runs in thread context. I wanted to spend the time earlier to see if seq_lock could be converted from a spinlock to a mutex, but I wanted the previous changes to go in and soak before I did that. So I went ahead and did the analysis and converting should work. And solve this problem.

2025-09-08drm/amdgpu: Wait for bootloader after PSPv11 resetLijo Lazar
Some PSPv11 SOCs take a longer time for PSP based mode-1 reset. Instead of checking for C2PMSG_33 status, add the callback wait_for_bootloader. Wait for bootloader to be back to steady state is already part of the generic mode-1 reset flow. Increase the retry count for bootloader wait and also fix the mask to prevent fake pass.

By default i_blkbits is set to PAGE_SIZE which causes iomap to mark the whole folio as uptodate even on a partial write. But fuseblk filesystems support choosing a blocksize smaller than PAGE_SIZE risking data corruption. Simply enforce PAGE_SIZE as blocksize for fuseblk's internal inode for now. - Prevent out-of-bounds acces in fuse_dev_write() when the number of bytes to be retrieved is truncated to the fc->max_pages limit. virtiofs: - Fix page faults for DAX page addresses.

2025-09-08fs: hpfs: Avoid multiple -Wflex-array-member-not-at-end warningsGustavo A. R. Silva
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. So, in order to avoid ending up with a flexible-array member in the middle of other structs, we use the `struct_group_tagged()` helper to create a new tagged `struct bplus_header_fixed`. This structure groups together all the members of the flexible `struct bplus_header` except the flexible array. As a result, the array is effectively separated from the rest of the members without modifying the memory layout of the flexible structure. We then change the type of the middle struct member currently causing trouble from `struct bplus_header` to `struct bplus_header_fixed`. We also want to ensure that when new members need to be added to the flexible structure, they are always included within the newly created tagged struct. For this, we use `static_assert()`. This ensures that the memory layout for both the flexible structure and the new tagged struct is the same after any changes. This approach avoids having to implement `struct bplus_header_fixed` as a completely separate structure, thus preventing having to maintain two independent but basically identical structures, closing the door to potential bugs in the future. We also use `container_of()` (via a wrapper) whenever we need to retrieve a pointer to the flexible structure, through which we can access the flexible-array member, if necessary. So, with these changes, fix 26 of the following type of warnings: fs/hpfs/hpfs.h:456:23: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] fs/hpfs/hpfs.h:498:23: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

2025-09-08drm/msm/a6xx: Make crashstate capture IFPC safeAkhil P Oommen
Now with IFPC, GX domain can collapse as soon as GPU becomes IDLE. So add gx_is_on check before accessing any GX registers during crashstate capture and recovery.

2025-09-08drm/msm/adreno: Disable IFPC when sysprof is activeAkhil P Oommen
Moving to IFPC state clears the 'Perfcounter Select' register setup by the userspace. So, lets block the IFPC when sysprof is active by using the perfcounter oob signal to the GMU.

2025-09-08drm/msm/a6xx: Fix hangcheck for IFPCAkhil P Oommen
From the hangcheck handler, KMD checks a few registers in GX domain to see if the GPU made any progress. But it cannot access those registers when IFPC is enabled. Since HW based hang detection is pretty decent, lets rely on it instead of these registers when IFPC is enabled.

2025-09-08drm/msm/a6xx: Poll AHB fence status in GPU IRQ handlerAkhil P Oommen
Even though the GX power domain is kept ON when there is a pending GPU interrupt, there is a small window of potential race with GMU where it may move the AHB fence to 'Drop' mode. Once the GMU sees the pending IRQ, it will move back the fence state to ALLOW mode. Close this race window by polling for AHB fence to ensure that it is in 'Allow' mode.

2025-09-08drm/msm/a6xx: Switch to GMU AO counterAkhil P Oommen
CP_ALWAYS_ON counter falls under GX domain which is collapsed during IFPC. So switch to GMU_ALWAYS_ON counter for any CPU reads since it is not impacted by IFPC. Both counters are clocked by same xo clock source.

2025-09-08drm/msm/adreno: Add fenced regwrite supportAkhil P Oommen
There are some special registers which are accessible even when GX power domain is collapsed during an IFPC sleep. Accessing these registers wakes up GPU from power collapse and allow programming these registers without additional handshake with GMU. This patch adds support for this special register write sequence.

2025-09-08drm/msm: Add an ftrace for gpu register accessAkhil P Oommen
With IFPC, there is a probability of accessing a GX domain register when it is collapsed, which leads to gmu fence errors. To debug this, we need to trace every gpu register accesses and identify the one just before a gmu fence error. So, add an ftrace to track all gpu register accesses.

A minor refactor to combine the subroutines for legacy a6xx GMUs under a single check. This helps to avoid an unnecessary check and return early from the subroutine for majority of a6xx gpus.

2025-09-08drm/msm/a6xx: Fix PDC sleep sequenceAkhil P Oommen
Since the PDC resides out of the GPU subsystem and cannot be reset in case it enters bad state, utmost care must be taken to trigger the PDC wake/sleep routines in the correct order. The PDC wake sequence can be exercised only after a PDC sleep sequence. Additionally, GMU firmware should initialize a few registers before the KMD can trigger a PDC sleep sequence. So PDC sleep can't be done if the GMU firmware has not initialized. Track these dependencies using a new status variable and trigger PDC sleep/wake sequences appropriately.
