[ Upstream commit 7f5f703210109366c1e1b685086c9b0a4897ea54 ] As per a commit from Qualcomm's downstream 6.1 kernel[0], the init sequence is missing setting the CMN_CTRL_OVERRIDE_EN bit back to 0 at the end, as per the 'latest' HPG revision (as of November 2023).

[ Upstream commit b08217a257215ed9130fce93d35feba66b49bf0a ] When enabling runtime PM for clock suppliers that also belong to a power domain, the following crash is thrown: error: synchronous external abort: 0000000096000010 [#1] PREEMPT SMP Workqueue: events_unbound deferred_probe_work_func pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : clk_mux_get_parent+0x60/0x90 lr : clk_core_reparent_orphans_nolock+0x58/0xd8 Call trace: clk_mux_get_parent+0x60/0x90 clk_core_reparent_orphans_nolock+0x58/0xd8 of_clk_add_hw_provider.part.0+0x90/0x100 of_clk_add_hw_provider+0x1c/0x38 imx95_bc_probe+0x2e0/0x3f0 platform_probe+0x70/0xd8 Enabling runtime PM without explicitly resuming the device caused the power domain cut off after clk_register() is called. As a result, a crash happens when the clock hardware provider is added and attempts to access the BLK_CTL register. Fix this by using devm_pm_runtime_enable() instead of pm_runtime_enable() and getting rid of the pm_runtime_disable() in the cleanup path.

2025-08-15PCI: endpoint: pci-epf-vntb: Fix the incorrect usage of __iomem attributeManivannan Sadhasivam1-1/+1
[ Upstream commit 61ae7f8694fb4b57a8c02a1a8d2b601806afc999 ] __iomem attribute is supposed to be used only with variables holding the MMIO pointer. But here, 'mw_addr' variable is just holding a 'void *' returned by pci_epf_alloc_space(). So annotating it with __iomem is clearly wrong. Hence, drop the attribute.

2025-08-15crypto: qat - fix virtual channel configuration for GEN6 devicesSuman Kumar Chakraborty2-6/+6
[ Upstream commit e83cfb8ff1433cc832d31b8cac967a1eb79d5b44 ] The TCVCMAP (Traffic Class to Virtual Channel Mapping) field in the PVC0CTL and PVC1CTL register controls how traffic classes are mapped to virtual channels in QAT GEN6 hardware. The driver previously wrote a default TCVCMAP value to this register, but this configuration was incorrect. Modify the TCVCMAP configuration to explicitly enable both VC0 and VC1, and map Traffic Classes 0 to 7 → VC0 and Traffic Class 8 → VC1. Replace FIELD_PREP() with FIELD_MODIFY() to ensure that only the intended TCVCMAP field is updated, preserving other bits in the register. This prevents unintended overwrites of unrelated configuration fields when modifying TC to VC mappings.

[ Upstream commit 78447d4545b2ea76ee04f4e46d473639483158b2 ] Since it's not currently safe to take device_lock() in the IOMMU probe path, that can race against really_probe() setting dev->driver before attempting to bind. The race itself isn't so bad, since we're only concerned with dereferencing dev->driver itself anyway, but sadly my attempt to implement the check with minimal churn leads to a kind of Time-of-Check to Time-of-Use (TOCTOU) issue, where dev->driver becomes valid after to_pci_driver(NULL) is already computed, and thus the check fails to work as intended. Will and I both hit this with the platform bus, but the pattern here is the same, so fix it for correctness too.

[ Upstream commit 0b075c011032f88d1cfde3b45d6dcf08b44140eb ] commit 5a3e85c3c397 ("pinmux: Use sequential access to access desc->pinmux data") tried to address the issue when two client of the same gpio calls pinctrl_select_state() for the same functionality, was resulting in NULL pointer issue while accessing desc->mux_owner. However, issue was not completely fixed due to the way it was handled and it can still result in the same NULL pointer. The issue occurs due to the following interleaving: cpu0 (process A) cpu1 (process B) pin_request() { pin_free() { mutex_lock() desc->mux_usecount--; //becomes 0 .. mutex_unlock() mutex_lock(desc->mux) desc->mux_usecount++; // becomes 1 desc->mux_owner = owner; mutex_unlock(desc->mux) mutex_lock(desc->mux) desc->mux_owner = NULL; mutex_unlock(desc->mux) This sequence leads to a state where the pin appears to be in use (`mux_usecount == 1`) but has no owner (`mux_owner == NULL`), which can cause NULL pointer on next pin_request on the same pin. Ensure that updates to mux_usecount and mux_owner are performed atomically under the same lock. Only clear mux_owner when mux_usecount reaches zero and no new owner has been assigned.

2025-08-15RDMA/hns: Get message length of ack_req from FWJunxian Huang3-11/+43
[ Upstream commit 2c2ec0106c0f1f12d4eefd11de318ac47557a750 ] ACK_REQ_FREQ indicates the number of packets (after MTU fragmentation) HW sends before setting an ACK request. When MTU is greater than or equal to 1024, the current ACK_REQ_FREQ value causes HW to request an ACK for every MTU fragment. The processing of a large number of ACKs severely impacts HW performance when sending large size payloads. Get message length of ack_req from FW so that we can adjust this parameter according to different situations. There are several constraints for ACK_REQ_FREQ: 1. mtu * (2 ^ ACK_REQ_FREQ) should not be too large, otherwise it may cause some unexpected retries when sending large payload. 2. ACK_REQ_FREQ should be larger than or equal to LP_PKTN_INI. 3. ACK_REQ_FREQ must be equal to LP_PKTN_INI when using LDCP or HC3 congestion control algorithm.

[ Upstream commit b4abeccb8d39db7d9b51cb0098d6458760b30a75 ] The __snp_alloc_firmware_pages() helper allocates pages in the firmware state (alloc + rmpupdate). In case of failed rmpupdate, it tries reclaiming pages with already changed state. This requires calling the PSP firmware and since there is sev_cmd_mutex to guard such calls, the helper takes a "locked" parameter so specify if the lock needs to be held. Most calls happen from snp_alloc_firmware_page() which executes without the lock. However commit 24512afa4336 ("crypto: ccp: Handle the legacy TMR allocation when SNP is enabled") switched sev_fw_alloc() from alloc_pages() (which does not call the PSP) to __snp_alloc_firmware_pages() (which does) but did not account for the fact that sev_fw_alloc() is called from __sev_platform_init_locked() (via __sev_platform_init_handle_tmr()) and executes with the lock held. Add a "locked" parameter to __snp_alloc_firmware_pages(). Make sev_fw_alloc() use the new parameter to prevent potential deadlock in rmp_mark_pages_firmware() if rmpupdate() failed.

[ Upstream commit 7554729de27daf6d54bcf8689d863bbe267828bf ] The pll1_d8 clock is enabled by the boot loader, and is ultimately a parent for numerous clocks, including those used by APB and AXI buses. Guodong Xu discovered that this clock got disabled while responding to getting -EPROBE_DEFER when requesting a reset controller. The needed clock (CLK_DMA, along with its parents) had already been enabled. To respond to the probe deferral return, the CLK_DMA clock was disabled, and this led to parent clocks also reducing their enable count. When the enable count for pll1_d8 was decremented it became 0, which caused it to be disabled. This led to a system hang. Marking that clock critical resolves this by preventing it from being disabled. Define a new macro CCU_FACTOR_GATE_DEFINE() to allow clock flags to be supplied for a CCU_FACTOR_GATE clock.

When a process runs in a non default user namespace, such check fails. Due to this when a process is running using Podman, it fails to create the flow resource. Since the RDMA device is a resource within a network namespace, use the network namespace associated with the RDMA device to determine its owning user namespace.

2025-08-15RDMA/ipoib: Use parent rdma device net namespaceMark Bloch1-0/+2
[ Upstream commit f1208b05574f63c52e88109d8c75afdf4fc6bf42 ] Use the net namespace of the underlying rdma device. After honoring the rdma device's namespace, the ipoib netdev now also runs in the same net namespace of the rdma device. Add an API to read the net namespace of the rdma device so that ULP such as IPoIB can use it to initialize its netdev.

2025-08-15clk: clk-axi-clkgen: fix fpfd_max frequency for zynqNuno Sá1-1/+1
[ Upstream commit ce8a9096699500e2c5bca09dde27b16edda5f636 ] The fpfd_max frequency should be set to 450 MHz instead of 300 MHz. Well, it actually depends on the platform speed grade but we are being conservative for ultrascale so let's be consistent. In a following change we will set these limits at runtime.

2025-08-15phy: qualcomm: phy-qcom-eusb2-repeater: Don't zero-out registersLuca Weiss1-55/+32
[ Upstream commit 31bc94de76026c527f82c238f414539a14f0f3e6 ] Zeroing out registers does not happen in the downstream kernel, and will "tune" the repeater in surely unexpected ways since most registers don't have a reset value of 0x0. Stop doing that and instead just set the registers that are in the init sequence (though long term I don't think there's actually PMIC-specific init sequences, there's board specific tuning, but that's a story for another day).
