2026-04-09platform/x86: hp-wmi: use mod_delayed_work to reset keep-alive timerEmre Cecanpunar
Currently, schedule_delayed_work() is used to queue the 90s keep-alive timer. If a user manually changes the fan speed at T=85s, schedule_delayed_work() leaves the existing timer in place as it is a no-op if the work is already pending. This results in the keep-alive timer firing unnecessarily at T=90s, just 5 seconds after the user action. Replace schedule_delayed_work() with mod_delayed_work() to reset the 90s timer whenever fan settings are applied. This guarantees a full 90s delay after every user interaction, preventing redundant keep-alive executions and improving efficiency.

2026-04-09platform/x86: hp-wmi: avoid cancel_delayed_work_sync from work handlerEmre Cecanpunar
hp_wmi_apply_fan_settings() uses cancel_delayed_work_sync() to stop the keep-alive timer in AUTO mode. However, since hp_wmi_apply_fan_settings() is also called from the keep-alive handler, a race condition with a sysfs write can cause the handler to wait on itself, leading to a deadlock. Replace cancel_delayed_work_sync() with cancel_delayed_work() in hp_wmi_apply_fan_settings() to avoid the self-flush deadlock.

hp_wmi_get_fan_count_userdefine_trigger() can fail, but its return value was silently ignored in hp_wmi_apply_fan_settings() for PWM_MODE_MAX/AUTO. Propagate these errors consistently. Additionally, handle the return value of hp_wmi_apply_fan_settings() in its callers by adding appropriate warnings on failure, and remove an unreachable "return 0" at the end of the function.

2026-04-09r8152: Add support for the RTL8157 hardwareBirger Koblitz
The RTL8157 uses a different packet descriptor format compared to the previous generation of chips. Add support for this format by adding a descriptor format structure into the r8152 structure and corresponding desc_ops functions which abstract the vlan-tag, tx/rx len and tx/rx checksum algorithms. Also, add support for the ADV indirect access interface of the RTL8157 and PHY setup. For initialization of the RTL8157, combine the existing RTL8156B and RTL8156 init functions and add RTL8157-specific functinality in order to improve code readability and maintainability. r8156_init() is now called with RTL_VER_10 and RTL_VER_11 for the RTL8156, with RTL_VER_12, RTL_VER_13 and RTL_VER_15 for the RTL8156B and with RTL_VER_16 for the RTL8157 and checks the version for chip-specific code. Also add USB power control functions for the RTL8157. Add support for the USB device ID of Realtek RTL8157-based adapters. Detect the RTL8157 as RTL_VER_16 and set it up.

2026-04-09drm/i915/gem: Drop check for changed VM in EXECBUFJoonas Lahtinen
Since the introduction of d4433c7600f7 ("drm/i915/gem: Use the proto-context to handle create parameters (v5)") it has not been possible for VM to change after context creation so the check will never fail. Sima's analysis: This check was added in f7ce8639f6ff ("drm/i915/gem: Split the context's obj:vma lut into its own mutex") but without any hint in the commit message as to why. In another hunk of that commit there's a hint though in __eb_add_lut: /* user racing with ctx set-vm */ This would mean that this bug was introduced in e0695db7298e ("drm/i915: Create/destroy VM (ppGTT) for use with contexts"), which allowed to change the gem_ctx->vm at runtime, opening up the race that was partially fixed in the earlier referenced commit about a year later. But it cannot be exploited anymore in anything remotely recent because with the introduction of proto-contexts we've made gem_ctx->vm invariant again, exactly to preemptively close all these potential issues. Specifically d4433c7600f7 ("drm/i915/gem: Use the proto-context to handle create parameters (v5)") is the vm specific part of the proto-context work. v3: - Include Sima's analysis and WARN_ON_ONCE v4: - Focus only on latest mainline codebase References: https://lore.kernel.org/all/20260324151741.29338-1-sosohero200@gmail.com/ Reported-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Linus Torvalds <torvalds@linuxfoundation.org> Cc: Simona Vetter <simona.vetter@ffwll.ch> Cc: Tvrtko Ursulin <tursulin@ursulin.net> Cc: Andi Shyti <andi.shyti@kernel.org> Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@igalia.com> Link: https://patch.msgid.link/20260409053111.8914-1-joonas.lahtinen@linux.intel.com (cherry picked from commit f6d4afc9ec6a0bc326151b35a7a3369369180079) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>

2026-04-09net: ipa: fix event ring index not programmed for IPA v5.0+Alexander Koskovich
For IPA v5.0+, the event ring index field moved from CH_C_CNTXT_0 to CH_C_CNTXT_1. The v5.0 register definition intended to define this field in the CH_C_CNTXT_1 fmask array but used the old identifier of ERINDEX instead of CH_ERINDEX. Without a valid event ring, GSI channels could never signal transfer completions. This caused gsi_channel_trans_quiesce() to block forever in wait_for_completion(). At least for IPA v5.2 this resolves an issue seen where runtime suspend, system suspend, and remoteproc stop all hanged forever. It also meant the IPA data path was completely non functional.

2026-04-08scsi: target: Don't validate ignored fields in PROUT PREEMPTStefan Hajnoczi
The PERSISTENT RESERVE OUT command's PREEMPT service action provides two different functions: 1. preempting persistent reservations and 2. removing registrations. In the latter case the spec says: b) ignore the contents of the SCOPE field and the TYPE field; The code currently validates the SCOPE and TYPE fields even when PREEMPT is called to remove registrations. This patch achieves spec compliance by validating the SCOPE and TYPE fields only when they will actually be used. To confirm my interpretation of the specification I tested against HPE 3PAR storage and found the TYPE field is indeed ignored in this case.

2026-04-08scsi: storvsc: Handle PERSISTENT_RESERVE_IN truncation for Hyper-V vFCLi Tian
The storvsc driver has become stricter in handling SRB status codes returned by the Hyper-V host. When using Virtual Fibre Channel (vFC) passthrough, the host may return SRB_STATUS_DATA_OVERRUN for PERSISTENT_RESERVE_IN commands if the allocation length in the CDB does not match the host's expected response size. Currently, this status is treated as a fatal error, propagating Host_status=0x07 [DID_ERROR] to the SCSI mid-layer. This causes userspace storage utilities (such as sg_persist) to fail with transport errors, even when the host has actually returned the requested reservation data in the buffer. Refactor the existing command-specific workarounds into a new helper function, storvsc_host_mishandles_cmd(), and add PERSISTENT_RESERVE_IN to the list of commands where SRB status errors should be suppressed for vFC devices. This ensures that the SCSI mid-layer processes the returned data buffer instead of terminating the command.

2026-04-08PCI: tegra194: Remove IRQF_ONESHOT flag during Endpoint interrupt registrationVidya Sagar
The Tegra PCIe Endpoint controller has a single interrupt line that is shared between multiple interrupt sources: 1. PCIe link state events (link up, hot reset done) 2. Configuration space events (Bus Master Enable changes) 3. DMA completion events The interrupt is currently registered with IRQF_ONESHOT, which keeps the interrupt line masked until the threaded handler completes. That blocks processing of DMA completion events (and other sources) while the threaded handler runs. Removing IRQF_ONESHOT is safe for the following reasons: 1. The hard IRQ handler (tegra_pcie_ep_hard_irq) properly acknowledges and clears all interrupt status bits in hardware before returning. This prevents interrupt storms and ensures the interrupt controller can re-enable the interrupt line immediately. 2. The follow-up commit adds handling in the hard IRQ for DMA completion events. Dropping IRQF_ONESHOT is required so the line is unmasked after the hard IRQ returns and those events can be serviced without being blocked by the threaded handler. 3. The threaded handler (tegra_pcie_ep_irq_thread) only processes link-up notifications and LTR message sending. These operations don't conflict with DMA interrupt processing and don't require the interrupt line to remain masked. This change enables both DMA driver and Endpoint controller driver to share the interrupt line without blocking each other.

2026-04-08PCI: tegra194: Assert CLKREQ# explicitly by defaultVidya Sagar
The Root Port's CLKREQ# signal is shared with a downstream PCIe switch and the endpoints behind it. By default, APPL_PINMUX_CLKREQ_OVERRIDE only overrides the CLKREQ# input to the controller (so REFCLK is enabled internally); it does not drive the CLKREQ# output pin low. Some PCIe switches (e.g. Broadcom PCIe Gen4) forward the Root Port's CLKREQ# to their downstream side and expect it to be driven low for REFCLK, even when the switch does not support CLK-PM or ASPM-L1SS. Without driving the output pin low, link-up can fail between the switch and endpoints. Clear APPL_PINMUX_CLKREQ_DEFAULT_VALUE so the CLKREQ# output pad is explicitly driven low. That makes the shared CLKREQ# line low on the wire and avoids link-up issues with such switches.

2026-04-08PCI: tegra194: Fix CBB timeout caused by DBI access before core power-onManikanta Maddireddy
When PERST# is deasserted twice (assert -> deassert -> assert -> deassert), a CBB (Control Backbone) timeout occurs at DBI register offset 0x8bc (PCIE_MISC_CONTROL_1_OFF). This happens because pci_epc_deinit_notify() and dw_pcie_ep_cleanup() are called before reset_control_deassert() powers on the controller core. The call chain that causes the timeout: pex_ep_event_pex_rst_deassert() pci_epc_deinit_notify() pci_epf_test_epc_deinit() pci_epf_test_clear_bar() pci_epc_clear_bar() dw_pcie_ep_clear_bar() __dw_pcie_ep_reset_bar() dw_pcie_dbi_ro_wr_en() <- Accesses 0x8bc DBI register reset_control_deassert(pcie->core_rst) <- Core powered on HERE The DBI registers, including PCIE_MISC_CONTROL_1_OFF (0x8bc), are only accessible after the controller core is powered on via reset_control_deassert(pcie->core_rst). Accessing them before this point results in a CBB timeout because the hardware is not yet operational. Fix this by moving pci_epc_deinit_notify() and dw_pcie_ep_cleanup() to after reset_control_deassert(pcie->core_rst), ensuring the controller is fully powered on before any DBI register accesses occur.
