2025-02-26bcachefs: Fix truncate sometimes failing and returning 1Kent Overstreet
__bch_truncate_folio() may return 1 to indicate dirtyness of the folio being truncated, needed for fpunch to get the i_size writes correct. But truncate was forgetting to clear ret, and sometimes returning it as an error. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-02-26bcachefs: Fix deadlockAlan Huang
This fixes two deadlocks: 1.pcpu_alloc_mutex involved one as pointed by syzbot[1] 2.recursion deadlock. The root cause is that we hold the bc lock during alloc_percpu, fix it by following the pattern used by __btree_node_mem_alloc().

2025-02-27arm64/mm: Fix Boot panic on Ampere AltraRyan Roberts
When the range of present physical memory is sufficiently small enough and the reserved address space for the linear map is sufficiently large enough, The linear map base address is randomized in arm64_memblock_init(). Prior to commit 62cffa496aac ("arm64/mm: Override PARange for !LPA2 and use it consistently"), we decided if the sizes were suitable with the help of the raw mmfr0.parange. But the commit changed this to use the sanitized version instead. But the function runs before the register has been sanitized so this returns 0, interpreted as a parange of 32 bits. Some fun wrapping occurs and the logic concludes that there is enough room to randomize the linear map base address, when really there isn't. So the top of the linear map ends up outside the reserved address space. Since the PA range cannot be overridden in the first place, restore the mmfr0 reading logic to its state prior to 62cffa496aac, where the raw register value is used.

According to the chip manual, the I2C register access type of Loongson-2K2000/LS7A is "B", so we can only access registers in byte form (readb()/writeb()). Although Loongson-2K0500/Loongson-2K1000 do not have similar constraints, register accesses in byte form also behave correctly. Also, in hardware, the frequency division registers are defined as two separate registers (high 8-bit and low 8-bit), so we just access them directly as bytes.

2025-02-26i2c: npcm: disable interrupt enable bit before devm_request_irqTyrone Ting
The customer reports that there is a soft lockup issue related to the i2c driver. After checking, the i2c module was doing a tx transfer and the bmc machine reboots in the middle of the i2c transaction, the i2c module keeps the status without being reset. Due to such an i2c module status, the i2c irq handler keeps getting triggered since the i2c irq handler is registered in the kernel booting process after the bmc machine is doing a warm rebooting. The continuous triggering is stopped by the soft lockup watchdog timer. Disable the interrupt enable bit in the i2c module before calling devm_request_irq to fix this issue since the i2c relative status bit is read-only. Here is the soft lockup log.

2025-02-26drm/xe: Eliminate usage of TIMESTAMP_OVERRIDEMatt Roper
Recent discussions with the hardware architects have revealed that the TIMESTAMP_OVERRIDE register is never expected to hold a valid/useful value on production hardware. That register would only get used by hardware workarounds (although there are none that use it today) or during early internal hardware testing. Due to lack of documentation it's not clear exactly what the driver should be doing if CTC_MODE[0] is set (or even whether that's a setting that would ever be encountered on real hardware), but it's definitely not what Xe and i915 have been doing. So drop the incorrect code trying to use TIMESTAMP_REGISTER. If the driver does encounter CTC_MODE[0] in the wild, we'll print a warning and just continue trying to use the crystal clock frequency since that's probably less incorrect than what we're doing today.

2025-02-26drm/xe/pxp: Don't kill queues while holding PXP locksDaniele Ceraolo Spurio
xe_exec_queue_kill can sleep, so we can't call it from under a spinlock. We can instead move the queues to a separate list and then kill them all after we release the spinlock. Furthermore, xe_exec_queue_kill can take the VM lock so we can't call it while holding the PXP mutex because the mutex is taken under VM lock at queue creation time. Note that while it is safe to call the kill without holding the mutex, we must call it after the PXP state has been updated, otherwise an app might be able to create a queue between the invalidation and the state update, which would break the state machine. Since being in the list is used to track whether RPM cleanup is needed, we can no longer defer that to queue_destroy, so we perform it immediately instead. v2: also avoid calling kill() under pxp->mutex.

2025-02-26drm/xe/eustall: Add support to handle dropped EU stall dataHarish Chegondi
If the user space doesn't read the EU stall data fast enough, it is possible that the EU stall data buffer can get filled, and if the hardware wants to write more data, it simply drops data due to unavailable buffer space. In that case, hardware sets a bit in a register. If the driver detects data drop, the driver read() returns -EIO error to let the user space know that HW has dropped data. The -EIO error is returned even if there is EU stall data in the buffer. A subsequent read by the user space returns the remaining EU stall data. v12: Move 'goto exit_drop;' to the next 'if (read_data_size == 0)' statement. v11: Clear drop bit even for empty data buffer as the data was read from the buffer in the previous read. v10: Reverted the changes back to v8: Clear the drop bits only after reading the data. v9: Move all data drop handling code to this patch Clear all drop data bits before returning -EIO.

2025-02-26drm/xe/uapi: Introduce API for EU stall samplingHarish Chegondi
A new hardware feature first introduced in PVC gives capability to periodically sample EU stall state and record counts for different stall reasons, on a per IP basis, aggregate across all EUs in a subslice and record the samples in a buffer in each subslice. Eventually, the aggregated data is written out to a buffer in the memory. This feature is also supported in XE2 and later architecture GPUs. Use an existing IOCTL - DRM_IOCTL_XE_OBSERVATION as the interface into the driver from the user space to do initial setup and obtain a file descriptor for the EU stall data stream. Input parameter to the IOCTL is a struct drm_xe_observation_param in which observation_type should be set to DRM_XE_OBSERVATION_TYPE_EU_STALL, observation_op should be DRM_XE_OBSERVATION_OP_STREAM_OPEN and param should point to a chain of drm_xe_ext_set_property structures in which each structure has a pair of property and value. The EU stall sampling input properties are defined in drm_xe_eu_stall_property_id enum. With the file descriptor obtained from DRM_IOCTL_XE_OBSERVATION, user space can enable and disable EU stall sampling with the IOCTLs: DRM_XE_OBSERVATION_IOCTL_ENABLE and DRM_XE_OBSERVATION_IOCTL_DISABLE. User space can also call poll() to check for availability of data in the buffer. The data can be read with read(). Finally, the file descriptor can be closed with close(). v11: Changed a couple of variables in struct eu_stall_open_properties from unsigned int to int. v10: Use extension number while parsing chain of extensions. Remove function description for static functions. Move code around as per review feedback. v9: Changed some u32 to unsigned int. Moved some code around as per review feedback from v8. v8: Used div_u64 instead of / to fix 32-bit build issue. Changed copyright year in xe_eu_stall.c/h to 2025. v7: Renamed input property DRM_XE_EU_STALL_PROP_EVENT_REPORT_COUNT to DRM_XE_EU_STALL_PROP_WAIT_NUM_REPORTS to be consistent with OA. Renamed the corresponding internal variables. Fixed some commit messages based on review feedback. v6: Change the input sampling rate to GPU cycles instead of GPU cycles multiplier.

2025-02-26affs: don't write overlarge OFS data block size fieldsSimon Tatham
If a data sector on an OFS floppy contains a value > 0x1e8 (the largest amount of data that fits in the sector after its header), then an Amiga reading the file can return corrupt data, by taking the overlarge size at its word and reading past the end of the buffer it read the disk sector into! The cause: when affs_write_end_ofs() writes data to an OFS filesystem, the new size field for a data block was computed by adding the amount of data currently being written (into the block) to the existing value of the size field. This is correct if you're extending the file at the end, but if you seek backwards in the file and overwrite _existing_ data, it can lead to the size field being larger than the maximum legal value. This commit changes the calculation so that it sets the size field to the max of its previous size and the position within the block that we just wrote up to.

2025-02-26affs: generate OFS sequence numbers starting at 1Simon Tatham
If I write a file to an OFS floppy image, and try to read it back on an emulated Amiga running Workbench 1.3, the Amiga reports a disk error trying to read the file. (That is, it's unable to read it _at all_, even to copy it to the NIL: device. It isn't a matter of getting the wrong data and being unable to parse the file format.) This is because the 'sequence number' field in the OFS data block header is supposed to be based at 1, but affs writes it based at 0. All three locations changed by this patch were setting the sequence number to a variable 'bidx' which was previously obtained by dividing a file position by bsize, so bidx will naturally use 0 for the first block. Therefore all three should add 1 to that value before writing it into the sequence number field. With this change, the Amiga successfully reads the file.

If there's any vendor-specific element in the subelements then the outer element parsing must not parse any vendor element at all. This isn't implemented correctly now due to parsing into the pointers and then overriding them, so explicitly skip vendor elements if any exist in the sub- elements (non-transmitted profile or per-STA profile).

2025-02-26wifi: mac80211: fix MLE non-inheritance parsingJohannes Berg
The code is erroneously applying the non-inheritance element to the inner elements rather than the outer, which is clearly completely wrong. Fix it by finding the MLE basic element at the beginning, and then applying the non-inheritance for the outer parsing. While at it, do some general cleanups such as not allowing callers to try looking for a specific non-transmitted BSS and link at the same time.

2025-02-26ALSA: hda/realtek: Fix microphone regression on ASUS N705UDAdrien Vergé
This fixes a regression introduced a few weeks ago in stable kernels 6.12.14 and 6.13.3. The internal microphone on ASUS Vivobook N705UD / X705UD laptops is broken: the microphone appears in userspace (e.g. Gnome settings) but no sound is detected. I bisected it to commit 3b4309546b48 ("ALSA: hda: Fix headset detection failure due to unstable sort"). I figured out the cause: 1. The initial pins enabled for the ALC256 driver are: cfg->inputs == { { pin=0x19, type=AUTO_PIN_MIC, is_headset_mic=1, is_headphone_mic=0, has_boost_on_pin=1 }, { pin=0x1a, type=AUTO_PIN_MIC, is_headset_mic=0, is_headphone_mic=0, has_boost_on_pin=1 } } 2. Since 2017 and commits c1732ede5e8 ("ALSA: hda/realtek - Fix headset and mic on several ASUS laptops with ALC256") and 28e8af8a163 ("ALSA: hda/realtek: Fix mic and headset jack sense on ASUS X705UD"), the quirk ALC256_FIXUP_ASUS_MIC is also applied to ASUS X705UD / N705UD laptops. This added another internal microphone on pin 0x13: cfg->inputs == { { pin=0x13, type=AUTO_PIN_MIC, is_headset_mic=0, is_headphone_mic=0, has_boost_on_pin=1 }, { pin=0x19, type=AUTO_PIN_MIC, is_headset_mic=1, is_headphone_mic=0, has_boost_on_pin=1 }, { pin=0x1a, type=AUTO_PIN_MIC, is_headset_mic=0, is_headphone_mic=0, has_boost_on_pin=1 } } I don't know what this pin 0x13 corresponds to. To the best of my knowledge, these laptops have only one internal microphone. 3. Before 2025 and commit 3b4309546b48 ("ALSA: hda: Fix headset detection failure due to unstable sort"), the sort function would let the microphone of pin 0x1a (the working one) *before* the microphone of pin 0x13 (the phantom one). 4. After this commit 3b4309546b48, the fixed sort function puts the working microphone (pin 0x1a) *after* the phantom one (pin 0x13). As a result, no sound is detected anymore. It looks like the quirk ALC256_FIXUP_ASUS_MIC is not needed anymore for ASUS Vivobook X705UD / N705UD laptops. Without it, everything works fine: - the internal microphone is detected and records actual sound, - plugging in a jack headset is detected and can record actual sound with it, - unplugging the jack headset makes the system go back to internal microphone and can record actual sound.
