2025-04-11platform/x86: x86-android-tablets: Add Vexia Edu Atla 10 tablet 5V dataHans de Goede
The Vexia EDU ATLA 10 tablet comes in 2 different versions with significantly different mainboards. The only outward difference is that the charging barrel on one is marked 5V and the other is marked 9V. Both are x86 ACPI tablets which ships with Android x86 as factory OS. with a DSDT which contains a bunch of I2C devices which are not actually there, causing various resource conflicts. Enumeration of these is skipped through the acpi_quirk_skip_i2c_client_enumeration(). Extend the existing support for the 9V version by adding support for manually instantiating the I2C devices which are actually present on the 5V version by adding the necessary device info to the x86-android-tablets module.

2025-04-11platform/x86: x86-android-tablets: Add "9v" to Vexia EDU ATLA 10 tablet symbolsHans de Goede
The Vexia EDU ATLA 10 tablet comes in 2 different versions with significantly different mainboards. The only outward difference is that the charging barrel on one is marked 5V and the other is marked 9V. Both need to be handled by the x86-android-tablets code. Add 9v to the symbols for the existing support for the 9V Vexia EDU ATLA 10 tablet symbols to prepare for adding support for the 5V version.

2025-04-11asus-laptop: Fix an uninitialized variableDenis Arefev
The value returned by acpi_evaluate_integer() is not checked, but the result is not always successful, so it is necessary to add a check of the returned value. If the result remains negative during three iterations of the loop, then the uninitialized variable 'val' will be used in the clamp_val() macro, so it must be initialized with the current value of the 'curr' variable. In this case, the algorithm should be less noisy. Found by Linux Verification Center (linuxtesting.org) with SVACE.

2025-04-11accel/ivpu: Flush pending jobs of device's workqueuesMaciej Falkowski
Use flush_work() instead of cancel_work_sync() for driver IRQ workqueues to guarantee that remaining pending work will be handled. This resolves two issues that were encountered where a driver was left in an incorrect state as the bottom-half was canceled: 1. Cancelling context-abort of a job that is still executing and is causing translation faults which is going to cause additional TDRs 2. Cancelling bottom-half of a DCT (duty-cycle throttling) request which will cause a device to not be adjusted to an external frequency request.

2025-04-11x86/xen: Fix __xen_hypercall_setfunc()Jason Andryuk
Hypercall detection is failing with xen_hypercall_intel() chosen even on an AMD processor. Looking at the disassembly, the call to xen_get_vendor() was removed. The check for boot_cpu_has(X86_FEATURE_CPUID) was used as a proxy for the x86_vendor having been set. When CONFIG_X86_REQUIRED_FEATURE_CPUID=y (the default value), DCE eliminates the call to xen_get_vendor(). An uninitialized value 0 means X86_VENDOR_INTEL, so the Intel function is always returned. Remove the if and always call xen_get_vendor() to avoid this issue.

2025-04-11iommu/ipmmu-vmsa: Register in a sensible orderRobin Murphy
IPMMU registers almost-initialised instances, but misses assigning the drvdata to make them fully functional, so initial calls back into ipmmu_probe_device() are likely to fail unnecessarily. Reorder this to work as it should, also pruning the long-out-of-date comment and adding the missing sysfs cleanup on error for good measure.

2025-04-11iommu: Clear iommu-dma ops on cleanupRobin Murphy
If iommu_device_register() encounters an error, it can end up tearing down already-configured groups and default domains, however this currently still leaves devices hooked up to iommu-dma (and even historically the behaviour in this area was at best inconsistent across architectures/drivers...) Although in the case that an IOMMU is present whose driver has failed to probe, users cannot necessarily expect DMA to work anyway, it's still arguable that we should do our best to put things back as if the IOMMU driver was never there at all, and certainly the potential for crashing in iommu-dma itself is undesirable. Make sure we clean up the dev->dma_iommu flag along with everything else.

2025-04-11iommu/vt-d: Wire up irq_ack() to irq_move_irq() for posted MSIsSean Christopherson
Set the posted MSI irq_chip's irq_ack() hook to irq_move_irq() instead of a dummy/empty callback so that posted MSIs process pending changes to the IRQ's SMP affinity. Failure to honor a pending set-affinity results in userspace being unable to change the effective affinity of the IRQ, as IRQD_SETAFFINITY_PENDING is never cleared and so irq_set_affinity_locked() always defers moving the IRQ. The issue is most easily reproducible by setting /proc/irq/xx/smp_affinity multiple times in quick succession, as only the first update is likely to be handled in process context.

Lockdep complains due pit_timer_init() using the lock in an IRQ-unsafe fashion, but it's a false positive, because there is no deadlock possible at that point due to init ordering: at the point where pit_timer_init() is called there is no other possible usage of i8253_lock because the system is still in the very early boot stage with no interrupts. But in any case, pit_timer_init() should disable interrupts before calling clockevent_i8253_disable() out of general principle, and to keep lockdep working even in this scenario.

2025-04-10ipv6: add exception routes to GC list in rt6_insert_exceptionXin Long
Commit 5eb902b8e719 ("net/ipv6: Remove expired routes with a separated list of routes.") introduced a separated list for managing route expiration via the GC timer. However, it missed adding exception routes (created by ip6_rt_update_pmtu() and rt6_do_redirect()) to this GC list. As a result, these exceptions were never considered for expiration and removal, leading to stale entries persisting in the routing table. This patch fixes the issue by calling fib6_add_gc_list() in rt6_insert_exception(), ensuring that exception routes are properly tracked and garbage collected when expired.

2025-04-10drm/msm/dpu: drop rogue intr_tear_rd_ptr valuesDmitry Baryshkov
The commit 5a9d50150c2c ("drm/msm/dpu: shift IRQ indices by 1") shifted IRQ indices by 1, making 'NO_IRQ' to be 0 rather than -1 (and allowing to skip the definition if the IRQ is not present). Several platform files were sketched before that commit, but got applied afterwards. As such, they inherited historical (and currently incorrect) setting of .intr_tear_rd_ptr = -1 for 'NO_IRQ' value. Drop that setting for all the affected platforms.

Replace all usage of raw_spinlock_t in queue_stack_maps.c with rqspinlock. This is a map type with a set of open syzbot reports reproducing possible deadlocks. Prior attempt to fix the issues was at [0], but was dropped in favor of this approach. Make sure we return the -EBUSY error in case of possible deadlocks or timeouts, just to make sure user space or BPF programs relying on the error code to detect problems do not break. With these changes, the map should be safe to access in any context, including NMIs.

This commit is a resubmission of commit 1fe1c66274fb ("drm/v3d: Fix Indirect Dispatch configuration for V3D 7.1.6 and later"), which was accidentally reverted by commit 91dae758bdb8 ("Merge tag 'drm-misc-next-2024-08-01' of https://gitlab.freedesktop.org/drm/misc/kernel into drm-next"), likely due to an unfortunate conflict resolution. From the original commit message: ``` `args->cfg[4]` is configured in Indirect Dispatch using the number of batches. Currently, for all V3D tech versions, `args->cfg[4]` equals the number of batches subtracted by 1. But, for V3D 7.1.6 and later, we must not subtract 1 from the number of batches. Implement the fix by checking the V3D tech version and revision. Fixes several `dEQP-VK.synchronization*` CTS tests related to Indirect Dispatch. ``` Fixes: 91dae758bdb8 ("Merge tag 'drm-misc-next-2024-08-01' of https://gitlab.freedesktop.org/drm/misc/kernel into drm-next") Signed-off-by: Maíra Canal <mcanal@igalia.com> Reviewed-by: Iago Toral Quiroga <itoral@igalia.com> Link: https://lore.kernel.org/r/20250409205051.9639-1-mcanal@igalia.com

[-Werror=attribute-warning] 580 | __read_overflow2_field(q_size_field, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors The fortified memcpy() routine enforces that the source is not overread and the destination is not overwritten if the size of either field and the size of the copy are known at compile time. The memcpy() in syscall_get_arguments() intentionally overreads from a1 to a5 in 'struct pt_regs' but this is bigger than the size of a1. Normally, this could be solved by wrapping a1 through a5 with struct_group() but there was already a struct_group() applied to these members in commit bba547810c66 ("riscv: tracing: Fix __write_overflow_field in ftrace_partial_regs()"). Just avoid memcpy() altogether and write the copying of args from regs manually, which clears up the warning at the expense of three extra lines of code.

2025-04-10Bluetooth: btnxpuart: Revert baudrate change in nxp_shutdownNeeraj Sanjay Kale
This reverts the change baudrate logic in nxp_shutdown. Earlier, when the driver was removed, it restored the controller baudrate to fw_init_baudrate, so that on re-loading the driver, things work fine. However, if the driver was removed while hci0 interface is down, the change baudrate vendor command could not be sent by the driver. When the driver was re-loaded, host and controller baudrate would be mismatched and hci initialization would fail. The only way to recover would be to reboot the system. This issue was fixed by moving the restore baudrate logic from nxp_serdev_remove() to nxp_shutdown(). This fix however caused another issue with the command "hciconfig hci0 reset", which makes hci0 DOWN and UP immediately. Running "bluetoothctl power off" and "bluetoothctl power on" in a tight loop works fine. To maintain support for "hciconfig reset" command, the above mentioned fix is reverted.

2025-04-10Bluetooth: increment TX timestamping tskey always for stream socketsPauli Virtanen
Documentation/networking/timestamping.rst implies TX timestamping OPT_ID tskey increments for each sendmsg. In practice: TCP socket increments it for all sendmsg, timestamping on or off, but UDP only when timestamping is on. The user-visible counter resets when OPT_ID is turned on, so difference can be seen only if timestamping is enabled for some packets only (eg. via SO_TIMESTAMPING CMSG).
