2025-05-23platform/x86/intel/pmc: Fix Arrow Lake U/H NPU PCI IDTodd Brandt
The ARL requires that the GMA and NPU devices both be in D3Hot in order for PC10 and S0iX to be achieved in S2idle. The original ARL-H/U addition to the intel_pmc_core driver attempted to do this by switching them to D3 in the init and resume calls of the intel_pmc_core driver. The problem is the ARL-H/U have a different NPU device and thus are not being properly set and thus S0iX does not work properly in ARL-H/U. This patch creates a new ARL-H specific device id that is correct and also adds the D3 fixup to the suspend callback. This way if the PCI devies drop from D3 to D0 after resume they can be corrected for the next suspend. Thus there is no dropout in S0iX.

2025-05-23i2c: designware: Don't warn about missing get_clk_rate_khzHeikki Krogerus
Converting the WARN_ON() to a dev_dbg() message in i2c_dw_clk_rate(). That removes the need to supply a dummy implementation for the callback (or alternatively a dummy clk device) when the fallback path is preferred where the existing values already in the clock registers are used - when a firmware has programmed the clock registers. The fallback path was introduced in commit 4fec76e0985c ("i2c: designware: Fix wrong setting for {ss,fs,hs}_{h,l}cnt registers").

2025-05-23i2c: designware: Invoke runtime suspend on quick slave re-registrationTan En De
Replaced pm_runtime_put() with pm_runtime_put_sync_suspend() to ensure the runtime suspend is invoked immediately when unregistering a slave. This prevents a race condition where suspend was skipped when unregistering and registering slave in quick succession. For example, consider the rapid sequence of `delete_device -> new_device -> delete_device -> new_device`. In this sequence, it is observed that the dw_i2c_plat_runtime_suspend() might not be invoked after `delete_device` operation. This is because after `delete_device` operation, when the pm_runtime_put() is about to trigger suspend, the following `new_device` operation might race and cancel the suspend. If that happens, during the `new_device` operation, dw_i2c_plat_runtime_resume() is skipped (since there was no suspend), which means `i_dev->init()`, i.e. i2c_dw_init_slave(), is skipped. Since i2c_dw_init_slave() is skipped, i2c_dw_configure_fifo_slave() is skipped too, which leaves `DW_IC_INTR_MASK` unconfigured. If we inspect the interrupt mask register using devmem, it will show as zero. Example shell script to reproduce the issue: ``` #!/bin/sh SLAVE_LADDR=0x1010 SLAVE_BUS=13 NEW_DEVICE=/sys/bus/i2c/devices/i2c-$SLAVE_BUS/new_device DELETE_DEVICE=/sys/bus/i2c/devices/i2c-$SLAVE_BUS/delete_device # Create initial device echo slave-24c02 $SLAVE_LADDR > $NEW_DEVICE sleep 2 # Rapid sequence of # delete_device -> new_device -> delete_device -> new_device echo $SLAVE_LADDR > $DELETE_DEVICE echo slave-24c02 $SLAVE_LADDR > $NEW_DEVICE echo $SLAVE_LADDR > $DELETE_DEVICE echo slave-24c02 $SLAVE_LADDR > $NEW_DEVICE # Using devmem to inspect IC_INTR_MASK will show as zero ``` Signed-off-by: Tan En De <ende.tan@starfivetech.com> Acked-by: Jarkko Nikula <jarkko.nikula@linux.intel.com> Link: https://lore.kernel.org/r/20250412023303.378600-1-ende.tan@starfivetech.com Signed-off-by: Andi Shyti <andi.shyti@kernel.org>
2025-05-23i2c-mlxbf: Improve I2C bus timing configurationChris Babroski
Update the I2C bus timing configuration on BlueField to match the configuration recommended and verified by the HW team. I2C block read failures were found on BlueField 3 during communication with a device that requires the use of repeated start conditions. Testing showed that these failures were caused by the I2C transaction getting aborted early due to a short bus "timeout" configuration value. This value determines how long the clock can be held low before the I2C transaction is aborted. Upon further inspection, it was also found that other I2C bus timing configuration values used by the kernel driver do not match the configuration that is recommended by the HW team and used in the BlueField BSP I2C drivers.

Platforms that do not support SLPC are exempted from the GuC PC support. The GuC PC does not get initialized, and neither do its BOs get created. This causes a problem because the GuC PC debugfs file is still being created. Whenever the file is attempted to read, it causes a NULL pointer dereference on the supposed BO of the GuC PC.

2025-05-23xen/arm: call uaccess_ttbr0_enable for dm_op hypercallStefano Stabellini
dm_op hypercalls might come from userspace and pass memory addresses as parameters. The memory addresses typically correspond to buffers allocated in userspace to hold extra hypercall parameters. On ARM, when CONFIG_ARM64_SW_TTBR0_PAN is enabled, they might not be accessible by Xen, as a result ioreq hypercalls might fail. See the existing comment in arch/arm64/xen/hypercall.S regarding privcmd_call for reference. For privcmd_call, Linux calls uaccess_ttbr0_enable before issuing the hypercall thanks to commit 9cf09d68b89a. We need to do the same for dm_op. This resolves the problem.

2025-05-23xen/x86: fix initial memory balloon targetRoger Pau Monne
When adding extra memory regions as ballooned pages also adjust the balloon target, otherwise when the balloon driver is started it will populate memory to match the target value and consume all the extra memory regions added. This made the usage of the Xen `dom0_mem=,max:` command line parameter for dom0 not work as expected, as the target won't be adjusted and when the balloon is started it will populate memory straight to the 'max:' value. It would equally affect domUs that have memory != maxmem. Kernels built with CONFIG_XEN_UNPOPULATED_ALLOC are not affected, because the extra memory regions are consumed by the unpopulated allocation driver, and then balloon_add_regions() becomes a no-op.

2025-05-23xen: swiotlb: Wire up map_resource callbackJohn Ernberg
When running Xen on iMX8QXP, an Arm SoC without IOMMU, DMA performed via its eDMA v3 DMA engine fail with a mapping error. The eDMA performs DMA between RAM and MMIO space, and it's the MMIO side that cannot be mapped. MMIO->RAM DMA access cannot be bounce buffered if it would straddle a page boundary and on Xen the MMIO space is 1:1 mapped for Arm, and x86 PV Dom0. Cases where MMIO space is not 1:1 mapped, such as x86 PVH Dom0, requires an IOMMU present to deal with the mapping. Considering the above the map_resource callback can just be wired to the existing dma_direct_map_resource() function. There is nothing to do for unmap so the unmap callback is not needed.

The sk->sk_socket is not locked or referenced in backlog thread, and during the call to skb_send_sock(), there is a race condition with the release of sk_socket. All types of sockets(tcp/udp/unix/vsock) will be affected. Race conditions: ''' CPU0 CPU1 backlog::skb_send_sock sendmsg_unlocked sock_sendmsg sock_sendmsg_nosec close(fd): ... ops->release() -> sock_map_close() sk_socket->ops = NULL free(socket) sock->ops->sendmsg ^ panic here ''' The ref of psock become 0 after sock_map_close() executed.

With this patch, if the backlog thread is running, sock_map_close() will wait for the backlog thread to complete and cancel all pending work. If no backlog running, any pending work that hasn't started by then will fail when invoked by sk_psock_get(), as the psock reference count have been zeroed, and sk_psock_drop() will cancel all jobs via cancel_delayed_work_sync(). In summary, we require synchronization to coordinate the backlog thread and close() thread.

2025-05-22memcg: objcg stock trylock without irq disablingShakeel Butt
There is no need to disable irqs to use objcg per-cpu stock, so let's just not do that but consume_obj_stock() and refill_obj_stock() will need to use trylock instead to avoid deadlock against irq. One consequence of this change is that the charge request from irq context may take slowpath more often but it should be rare.

2025-05-22memcg: no stock lock for cpu hot-unplugShakeel Butt
Previously on the cpu hot-unplug, the kernel would call drain_obj_stock() with objcg local lock. However local lock was not needed as the stock which was accessed belongs to a dead cpu but we kept it there to disable irqs as drain_obj_stock() may call mod_objcg_mlstate() which required irqs disabled. However there is no need to disable irqs now for mod_objcg_mlstate(), so we can remove the local lock altogether from cpu hot-unplug path.

2025-05-22memcg: memcg_rstat_updated re-entrant safe against irqsShakeel Butt
Patch series "memcg: make memcg stats irq safe", v2. This series converts memcg stats to be irq safe i.e. memcg stats can be updated in any context (task, softirq or hardirq) without disabling the irqs. This is still not nmi-safe on all architectures but after this series converting memcg charging and stats nmi-safe will be easier. This patch (of 7): memcg_rstat_updated() is used to track the memcg stats updates for optimizing the flushes. At the moment, it is not re-entrant safe and the callers disabled irqs before calling. However to achieve the goal of updating memcg stats without irqs, memcg_rstat_updated() needs to be re-entrant safe against irqs. This patch makes memcg_rstat_updated() re-entrant safe using this_cpu_* ops. On archs with CONFIG_ARCH_HAS_NMI_SAFE_THIS_CPU_OPS, this patch is also making memcg_rstat_updated() nmi safe.

2025-05-22mm: khugepaged: decouple SHMEM and file folios' collapseBaolin Wang
Originally, the file pages collapse was intended for tmpfs/shmem to merge into THP in the background. However, now not only tmpfs/shmem can support large folios, but some other file systems (such as XFS, erofs ...) also support large folios. Therefore, it is time to decouple the support of file folios collapse from SHMEM.
