2026-01-20mmc: rtsx_pci_sdmmc: implement sdmmc_card_busy functionMatthew Schwartz1-0/+41
rtsx_pci_sdmmc does not have an sdmmc_card_busy function, so any voltage switches cause a kernel warning, "mmc0: cannot verify signal voltage switch." Copy the sdmmc_card_busy function from rtsx_pci_usb to rtsx_pci_sdmmc to fix this.

2026-01-20drm/atmel-hlcdc: destroy properly the plane state in the reset callbackLudovic Desroches1-26/+26
If there is a plane state to destroy when doing a plane reset, destroy it using the atmel_hlcdc_plane_destroy_state() function. So we call __drm_atomic_helper_plane_destroy_state() and avoid code duplication.

2026-01-20drm/rockchip: dw_hdmi_qp: Fix RK3576 HPD interrupt handlingCristian Ciocaltea1-6/+1
The threaded interrupt handler on RK3576 checks HPD IRQ status before deciding to continue with interrupt clearing and unmasking. This is not only redundant, since a similar verification has been already performed by the hard IRQ handler before masking the interrupt, but is also error prone, because it might happen that hardware clears the status register right after the masking operation completes, and before the threaded handler reads its value. The consequence is that HPD IRQ gets never unmasked, which breaks hotplug detection until reloading the driver or rebooting the system. Drop the unnecessary verification of the HPD interrupt status from the threaded interrupt handler.

2026-01-20irqchip/gic-v3-its: Avoid truncating memory addressesArnd Bergmann1-4/+4
On 32-bit machines with CONFIG_ARM_LPAE, it is possible for lowmem allocations to be backed by addresses physical memory above the 32-bit address limit, as found while experimenting with larger VMSPLIT configurations. This caused the qemu virt model to crash in the GICv3 driver, which allocates the 'itt' object using GFP_KERNEL. Since all memory below the 4GB physical address limit is in ZONE_DMA in this configuration, kmalloc() defaults to higher addresses for ZONE_NORMAL, and the ITS driver stores the physical address in a 32-bit 'unsigned long' variable. Change the itt_addr variable to the correct phys_addr_t type instead, along with all other variables in this driver that hold a physical address. The gicv5 driver correctly uses u64 variables, while all other irqchip drivers don't call virt_to_phys or similar interfaces. It's expected that other device drivers have similar issues, but fixing this one is sufficient for booting a virtio based guest.

2026-01-20pinctrl: spacemit: support I/O power domain configurationTroy Mitchell1-3/+126
Dual-voltage GPIO banks default to 3.3V operation. Even when a bank is externally supplied with 1.8V, the internal logic remains in the 3.3V domain, leading to functional failures. Add support for programming the IO domain power control registers to allow explicit configuration for 1.8V operation. These registers are secure due to hardware safety constraints. Specifically, configuring the domain for 1.8V while externally supplying 3.3V causes back-powering and potential pin damage. Consequently, access requires unlocking the AIB Secure Access Register (ASAR) in the APBC block before any read or write operation.

In preparation for changing the static mm_struct definitions to cover for the additional space required, change the cpu_bitmap type from "unsigned long" to "char", require an unsigned long alignment of the flexible array, and rename the field from "cpu_bitmap" to "flexible_array". Introduce the MM_STRUCT_FLEXIBLE_ARRAY_INIT macro to statically initialize the flexible array. This covers the init_mm and efi_mm static definitions. This is a preparation step for fixing the missing mm_cid size for static mm_struct definitions.

2026-01-19net/mlx5e: Conditionally create async ICOSQWilliam Tu4-29/+50
The async ICOSQ is only required by TLS RX (for re-sync flow) and XSK TX. Create it only when these features are enabled instead of always allocating it. This reduces per-channel memory usage, saves hardware resources, improves latency, and decreases the default number of SQs (from 3 to 2) and CQs (from 4 to 3). It also speeds up channel open/close operations for a netdev when async ICOSQ is not needed. Currently when TLS RX is enabled, there is no channel reset triggered. As a result, async ICOSQ allocation is not triggered, causing a NULL pointer crash. One solution is to do channel reset every time when toggling TLS RX. However, it's not straightforward as the offload state matters only on connection creation, and can go on beyond the channels reset. Instead, introduce a new field 'ktls_rx_was_enabled': if TLS RX is enabled for the first time: reset channels, create async ICOSQ, set the field. From that point on, no need to reset channels for any TLS RX enable/disable. Async ICOSQ will always be needed. For XSK TX, async ICOSQ is used in wakeup control and is guaranteed to have async ICOSQ allocated. This improves the latency of interface up/down operations when it applies. Perf numbers: NIC: Connect-X7. Test: Latency of interface up + down operations. Measured 20% speedup. Saving ~0.36 sec for 248 channels (~1.45 msec per channel).

Dynamically allocate async ICOSQ. ICO (Internal Communication Operations) is for driver to communicate with the HW, and it's not used for traffic. Currently mlx5 driver has sync and async ICO send queues. The async ICOSQ means that it's not necessarily under NAPI context protection. The patch is in preparation for the later patch to detect its usage and enable it when necessary.

2026-01-19net/mlx5e: Use regular ICOSQ for triggering NAPIWilliam Tu5-5/+37
Before the cited commit, ICOSQ is used to post NOP WQE to trigger hardware interrupt and start NAPI, but this mechanism suffers from a race condition: mlx5e_alloc_rx_mpwqe may post UMR WQEs to ICOSQ _before_ NOP WQE is posted. The cited commit fixes the issue by replacing ICOSQ with async ICOSQ, as a new way to post the NOP WQE to trigger the hardware interrupt and NAPI. The patch changes it back by replacing async ICOSQ with regular ICOSQ, for the purpose of saving memory in later patches, and solves the issue by adding a new SQ state, MLX5E_SQ_STATE_LOCK_NEEDED for syncing the start of NAPI. What it does: - Switch trigger path from async ICOSQ to regular ICOSQ to reduce need for async SQ. - Introduce MLX5E_SQ_STATE_LOCK_NEEDED and mlx5e_icosq_sync_lock(), unlock() to prevent the race where UMR WQEs could be posted before the NOP WQE used to trigger NAPI. - Use synchronize_net() once per trigger cycle to quiesce in-flight softirqs before serializing the NOP WQE and any UMR postings via the ICOSQ lock. - Wrap ICOSQ UMR posting in en_rx.c and xsk/rx.c with the new conditional lock. The conditional locking approach is critical for performance: always locking would impose unnecessary overhead. Synchronization is not needed between regular NAPI cycles once the channel is activated and running. The lock is only required to protect against the race during channel activation—specifically, when the very first NOP WQE is posted to trigger NAPI. After that initial trigger, normal NAPI polling handles subsequent work without contention. The MLX5E_SQ_STATE_LOCK_NEEDED flag ensures we pay the synchronization cost only when necessary.
