2025-05-16arm64: dts: qcom: x1e80100-hp-x14: drop bogus USB retimerJohan Hovold
Jens reported that the sanity checks added to the new ps883x USB retimer driver breaks USB and display on the HP X14. Turns out the X14 only has a retimer on one of the ports, but this initially went unnoticed due to the missing sanity check (and error handling) in the retimer driver. Drop the non-existing retimer from the devicetree to enable the second USB port and the display subsystem. Note that this also matches the ACPI tables.

2025-05-16arm64: mm: Drop redundant check in pmd_trans_huge()Gavin Shan
pmd_val(pmd) is redundant because a positive pmd_present(pmd) ensures a positive pmd_val(pmd) according to their definitions like below. #define pmd_val(x) ((x).pmd) #define pmd_present(pmd) pte_present(pmd_pte(pmd)) #define pte_present(pte) (pte_valid(pte) || pte_present_invalid(pte)) #define pte_valid(pte) (!!(pte_val(pte) & PTE_VALID)) #define pte_present_invalid(pte) \ ((pte_val(pte) & (PTE_VALID | PTE_PRESENT_INVALID)) == PTE_PRESENT_INVALID) pte_present() can't be positive unless either of the flag PTE_VALID or PTE_PRESENT_INVALID is set. In this case, pmd_val(pmd) should be positive either. So lets drop the redundant check pmd_val(pmd) and no functional changes intended.

2025-05-16arm64/mm: Re-organise setting up FEAT_S1PIE registers PIRE0_EL1 and PIR_EL1Anshuman Khandual
mov_q cannot really move PIE_E[0|1] macros into a general purpose register as expected if those macro constants contain some 128 bit layout elements, that are required for D128 page tables. The primary issue is that for D128, PIE_E[0|1] are defined in terms of 128-bit types with shifting and masking, which the assembler can't accommodate. Instead pre-calculate these PIRE0_EL1/PIR_EL1 constants into asm-offsets.h based PIE_E0_ASM/PIE_E1_ASM which can then be used in arch/arm64/mm/proc.S. While here also drop PTE_MAYBE_NG/PTE_MAYBE_SHARED assembly overrides which are not required any longer, as the compiler toolchains are smart enough to compute both the PIE_[E0|E1]_ASM constants in all scenarios.

2025-05-16KVM: arm64: Make MTE_frac masking conditional on MTE capabilityBen Horgan
If MTE_frac is masked out unconditionally then the guest will always see ID_AA64PFR1_EL1_MTE_frac as 0. However, a value of 0 when ID_AA64PFR1_EL1_MTE is 2 indicates that MTE_ASYNC is supported. Hence, for a host with ID_AA64PFR1_EL1_MTE==2 and ID_AA64PFR1_EL1_MTE_frac==0xf (MTE_ASYNC unsupported) the guest would see MTE_ASYNC advertised as supported whilst the host does not support it. Hence, expose the sanitised value of MTE_frac to the guest and user-space. As MTE_frac was previously hidden, always 0, and KVM must accept values from KVM provided by user-space, when ID_AA64PFR1_EL1.MTE is 2 allow user-space to set ID_AA64PFR1_EL1.MTE_frac to 0. However, ignore it to avoid incorrectly claiming hardware support for MTE_ASYNC in the guest. Note that linux does not check the value of ID_AA64PFR1_EL1_MTE_frac and wrongly assumes that MTE async faults can be generated even on hardware that does nto support them. This issue is not addressed here.

2025-05-16arm64/sysreg: Expose MTE_frac so that it is visible to KVMBen Horgan
KVM exposes the sanitised ID registers to guests. Currently these ignore the ID_AA64PFR1_EL1.MTE_frac field, meaning guests always see a value of zero. This is a problem for platforms without the MTE_ASYNC feature where ID_AA64PFR1_EL1.MTE==0x2 and ID_AA64PFR1_EL1.MTE_frac==0xf. KVM forces MTE_frac to zero, meaning the guest believes MTE_ASYNC is supported, when no async fault will ever occur. Before KVM can fix this, the architecture needs to sanitise the ID register field for MTE_frac. Linux itself does not use MTE_frac field and just assumes MTE async faults can be generated if MTE is supported.

2025-05-15arm64: dts: rockchip: Improve LED config for NanoPi R5SDiederik de Haas
The NanoPi R5S has 4 GPIO LEDs, a RED one for SYStem power and 3 green LEDs meant to indicate that a cable is connected to either of the 2.5GbE LAN ports or the 1GbE WAN port. In the NanoPi R5S schematic (2204; page 19) as well as on the PCB and on the case, SYS is used and not POWER. So replace 'power' with 'sys'. But keep the 'power_led' label/phandle even though the kernel doesn't use it, but it may be used outside of it. The SYStem LED already had "heartbeat" as its default-trigger. Set the default-trigger to "netdev" for the NICs so they will show when LAN1/LAN2/WAN is connected and set their default-state to "off". Also assign labels as close as possible to the labels on the case, while still being descriptive enough in their own right.

2025-05-15arm64: dts: rockchip: disable unrouted USB controllers and PHY on RK3399 ↵Quentin Schulz
Puma with Haikou The u2phy0_host port is the part of the USB PHY0 (namely the HOST0_DP/DM lanes) which routes directly to the USB2.0 HOST controller[1]. The other lanes of the PHY are routed to the USB3.0 OTG controller (dwc3), which we do use. The HOST0_DP/DM lanes aren't routed on RK3399 Puma so let's simply disable the USB2.0 controllers. USB3 OTG has been known to be unstable on RK3399 Puma Haikou for a while, one of the recurring issues being that only USB2 is detected and not USB3 in host mode. Reading the justification above and seeing that we are keeping u2phy0_host in the Haikou carrierboard DTS probably may have bothered you since it should be changed to u2phy0_otg. The issue is that if it's switched to that, USB OTG on Haikou is entirely broken. I have checked the routing in the Gerber file, the lanes are going to the expected ball pins (that is, NOT HOST0_DP/DM). u2phy0_host is for sure the wrong part of the PHY to use, but it's the only one that works at the moment for that board so keep it until we figure out what exactly is broken.

2025-05-15arm64: dts: rockchip: fix internal USB hub instability on RK3399 PumaLukasz Czechowski
Currently, the onboard Cypress CYUSB3304 USB hub is not defined in the device tree, and hub reset pin is provided as vcc5v0_host regulator to usb phy. This causes instability issues, as a result of improper reset duration. The fixed regulator device requests the GPIO during probe in its inactive state (except if regulator-boot-on property is set, in which case it is requested in the active state). Considering gpio is GPIO_ACTIVE_LOW for Puma, it means it’s driving it high. Then the regulator gets enabled (because regulator-always-on property), which drives it to its active state, meaning driving it low. The Cypress CYUSB3304 USB hub actually requires the reset to be asserted for at least 5 ms, which we cannot guarantee right now since there's no delay in the current config, meaning the hub may sometimes work or not. We could add delay as offered by fixed-regulator but let's rather fix this by using the proper way to model onboard USB hubs. Define hub_2_0 and hub_3_0 nodes, as the onboard Cypress hub consist of two 'logical' hubs, for USB2.0 and USB3.0. Use the 'reset-gpios' property of hub to assign reset pin instead of using regulator. Rename the vcc5v0_host regulator to cy3304_reset to be more meaningful. Pin is configured to output-high by default, which sets the hub in reset state during pin controller initialization. This allows to avoid double enumeration of devices in case the bootloader has setup the USB hub before the kernel. The vdd-supply and vdd2-supply properties in hub nodes are added to provide correct dt-bindings, although power supplies are always enabled based on HW design.

2025-05-14arm64/mm: Permit lazy_mmu_mode to be nestedRyan Roberts
lazy_mmu_mode is not supposed to permit nesting. But in practice this does happen with CONFIG_DEBUG_PAGEALLOC, where a page allocation inside a lazy_mmu_mode section (such as zap_pte_range()) will change permissions on the linear map with apply_to_page_range(), which re-enters lazy_mmu_mode (see stack trace below). The warning checking that nesting was not happening was previously being triggered due to this. So let's relax by removing the warning and tolerate nesting in the arm64 implementation. The first (inner) call to arch_leave_lazy_mmu_mode() will flush and clear the flag such that the remainder of the work in the outer nest behaves as if outside of lazy mmu mode. This is safe and keeps tracking simple. Code review suggests powerpc deals with this issue in the same way. ------------[ cut here ]------------ WARNING: CPU: 6 PID: 1 at arch/arm64/include/asm/pgtable.h:89 __apply_to_page_range+0x85c/0x9f8 Modules linked in: ip_tables x_tables ipv6 CPU: 6 UID: 0 PID: 1 Comm: systemd Not tainted 6.15.0-rc5-00075-g676795fe9cf6 #1 PREEMPT Hardware name: QEMU KVM Virtual Machine, BIOS 2024.08-4 10/25/2024 pstate: 40400005 (nZcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : __apply_to_page_range+0x85c/0x9f8 lr : __apply_to_page_range+0x2b4/0x9f8 sp : ffff80008009b3c0 x29: ffff80008009b460 x28: ffff0000c43a3000 x27: ffff0001ff62b108 x26: ffff0000c43a4000 x25: 0000000000000001 x24: 0010000000000001 x23: ffffbf24c9c209c0 x22: ffff80008009b4d0 x21: ffffbf24c74a3b20 x20: ffff0000c43a3000 x19: ffff0001ff609d18 x18: 0000000000000001 x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000003 x14: 0000000000000028 x13: ffffbf24c97c1000 x12: ffff0000c43a3fff x11: ffffbf24cacc9a70 x10: ffff0000c43a3fff x9 : ffff0001fffff018 x8 : 0000000000000012 x7 : ffff0000c43a4000 x6 : ffff0000c43a4000 x5 : ffffbf24c9c209c0 x4 : ffff0000c43a3fff x3 : ffff0001ff609000 x2 : 0000000000000d18 x1 : ffff0000c03e8000 x0 : 0000000080000000 Call trace: __apply_to_page_range+0x85c/0x9f8 (P) apply_to_page_range+0x14/0x20 set_memory_valid+0x5c/0xd8 __kernel_map_pages+0x84/0xc0 get_page_from_freelist+0x1110/0x1340 __alloc_frozen_pages_noprof+0x114/0x1178 alloc_pages_mpol+0xb8/0x1d0 alloc_frozen_pages_noprof+0x48/0xc0 alloc_pages_noprof+0x10/0x60 get_free_pages_noprof+0x14/0x90 __tlb_remove_folio_pages_size.isra.0+0xe4/0x140 __tlb_remove_folio_pages+0x10/0x20 unmap_page_range+0xa1c/0x14c0 unmap_single_vma.isra.0+0x48/0x90 unmap_vmas+0xe0/0x200 vms_clear_ptes+0xf4/0x140 vms_complete_munmap_vmas+0x7c/0x208 do_vmi_align_munmap+0x180/0x1a8 do_vmi_munmap+0xac/0x188 __vm_munmap+0xe0/0x1e0 __arm64_sys_munmap+0x20/0x38 invoke_syscall+0x48/0x104 el0_svc_common.constprop.0+0x40/0xe0 do_el0_svc+0x1c/0x28 el0_svc+0x4c/0x16c el0t_64_sync_handler+0x10c/0x140 el0t_64_sync+0x198/0x19c irq event stamp: 281312 hardirqs last enabled at (281311): [<ffffbf24c780fd04>] bad_range+0x164/0x1c0 hardirqs last disabled at (281312): [<ffffbf24c89c4550>] el1_dbg+0x24/0x98 softirqs last enabled at (281054): [<ffffbf24c752d99c>] handle_softirqs+0x4cc/0x518 softirqs last disabled at (281019): [<ffffbf24c7450694>] __do_softirq+0x14/0x20 ---[ end trace 0000000000000000 ]--- Fixes: 5fdd05efa1cd ("arm64/mm: Batch barriers when updating kernel mappings") Reported-by: Catalin Marinas <catalin.marinas@arm.com> Closes: https://lore.kernel.org/linux-arm-kernel/aCH0TLRQslXHin5Q@arm.com/ Signed-off-by: Ryan Roberts <ryan.roberts@arm.com> Reviewed-by: Catalin Marinas <catalin.marinas@arm.com> Link: https://lore.kernel.org/r/20250512150333.5589-1-ryan.roberts@arm.com Signed-off-by: Will Deacon <will@kernel.org>
2025-05-14arm64/mm: Disable barrier batching in interrupt contextsRyan Roberts
Commit 5fdd05efa1cd ("arm64/mm: Batch barriers when updating kernel mappings") enabled arm64 kernels to track "lazy mmu mode" using TIF flags in order to defer barriers until exiting the mode. At the same time, it added warnings to check that pte manipulations were never performed in interrupt context, because the tracking implementation could not deal with nesting. But it turns out that some debug features (e.g. KFENCE, DEBUG_PAGEALLOC) do manipulate ptes in softirq context, which triggered the warnings. So let's take the simplest and safest route and disable the batching optimization in interrupt contexts. This makes these users no worse off than prior to the optimization. Additionally the known offenders are debug features that only manipulate a single PTE, so there is no performance gain anyway. There may be some obscure case of encrypted/decrypted DMA with the dma_free_coherent called from an interrupt context, but again, this is no worse off than prior to the commit. Some options for supporting nesting were considered, but there is a difficult to solve problem if any code manipulates ptes within interrupt context but *outside of* a lazy mmu region. If this case exists, the code would expect the updates to be immediate, but because the task context may have already been in lazy mmu mode, the updates would be deferred, which could cause incorrect behaviour. This problem is avoided by always ensuring updates within interrupt context are immediate.

2025-05-14arm64: dts: marvell: uDPU: define pinctrl state for alarm LEDsGabor Juhos
The two alarm LEDs of on the uDPU board are stopped working since commit 78efa53e715e ("leds: Init leds class earlier"). The LEDs are driven by the GPIO{15,16} pins of the North Bridge GPIO controller. These pins are part of the 'spi_quad' pin group for which the 'spi' function is selected via the default pinctrl state of the 'spi' node. This is wrong however, since in order to allow controlling the LEDs, the pins should use the 'gpio' function. Before the commit mentined above, the 'spi' function is selected first by the pinctrl core before probing the spi driver, but then it gets overridden to 'gpio' implicitly via the devm_gpiod_get_index_optional() call from the 'leds-gpio' driver. After the commit, the LED subsystem gets initialized before the SPI subsystem, so the function of the pin group remains 'spi' which in turn prevents controlling of the LEDs. Despite the change of the initialization order, the root cause is that the pinctrl state definition is wrong since its initial commit 0d45062cfc89 ("arm64: dts: marvell: Add device tree for uDPU board"), To fix the problem, override the function in the 'spi_quad_pins' node to 'gpio' and move the pinctrl state definition from the 'spi' node into the 'leds' node.

2025-05-14KVM: arm64: Don't feed uninitialised data to HCR_EL2Marc Zyngier
When the guest executes an AT S1E{0,1} from EL2, and that its HCR_EL2.{E2H,TGE}=={1,1}, then this is a pure S1 translation that doesn't involve a guest-supplied S2, and the full S1 context is already in place. This allows us to take a shortcut and avoid save/restoring a bunch of registers. However, we set HCR_EL2 to a value suitable for the use of AT in guest context. And we do so by using the value that we saved. Or not. In the case described above, we restore whatever junk was on the stack, and carry on with it until the next entry. Needless to say, this is completely broken. But this also triggers the realisation that saving HCR_EL2 is a bit pointless. We are always in host context at the point where reach this code, and what we program to enter the guest is a known value (vcpu->arch.hcr_el2). Drop the pointless save/restore, and wrap the AT operations with writes that switch between guest and host values for HCR_EL2.

2025-05-14KVM: arm64: Fix PAR_EL1.{PTW,S} reporting on AT S1E*Marc Zyngier
When an AT S1E* operation fails, we need to report whether the translation failed at S2, and whether this was during a S1 PTW. But these two bits are not independent. PAR_EL1.PTW can only be set of PAR_EL1.S is also set, and PAR_EL1.S can only be set on its own when the full S1 PTW has succeeded, but that the access itself is reporting a fault at S2. As a result, it makes no sense to carry both ptw and s2 as parameters to fail_s1_walk(), and they should be unified. This fixes a number of cases where we were reporting PTW=1 *and* S=0, which makes no sense.
