[Fix] For backport-iwlwifi-dkms, in the master branch HEAD it has commit 5a3d01a7ea635 ("[BUGFIX] wifi: iwlwifi: mvm: avoid oversized UATS command copy"), which is incomplete that Intel gives an additional patch titled "wifi: iwlwifi: mvm: don't map the stack to DMA". These two patches combined equal to https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi- next.git/commit/?h=fixes&id=e0c121d545134af886b28c4c26d91abf5dd39c17 ("wifi: iwlwifi: mvm: avoid oversized UATS command copy"). However the later breaks builds against kernel < 7.0 and therefore it takes additional backport related to kmalloc_obj family from commit 4862faa9c3dd ("Merge remote-tracking branch 'auto/master'"). Later, it's found to cause another PHC register failure warning on kernels >= 7.0, and it takes backports related to settime64 from another commit 5076fafb8e33 ("Merge remote-tracking branch 'auto/master'"). For the linux kernel in-tree iwlwifi driver, Intel proposed a fix https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi- next.git/commit/?h=fixes&id=e0c121d545134af886b28c4c26d91abf5dd39c17 ("wifi: iwlwifi: mvm: avoid oversized UATS command copy") that is already in linux-next. While v7.0 has already commit 81d90d93d22ca ("wifi: iwlwifi: Implement settime64 as stub for MVM/MLD PTP") that fixes the PHC register problem, no additional fix is needed. [Test Plan] There are 4 cases: * linux-unstable-7.1/stonking * linux-generic-7.0/resolute * linux-oem-7.0/resolute * backport-iwlwifi-dkms/stoking - tested against linux-unstable-7.1/stonking * backport-iwlwifi-dkms/resolute - tested against linux-generic-7.0/resolute, linux-oem-7.0/resolute and linux-oem-6.17/noble To test kernel packages: 1. Install kernels from corresponding -proposed pocket. 2. Boot from some Intel Wildcat Lake platforms with an Intel AX211 wireless module installed. Here I use Intel WCL-U RVP. 3. The dmesg should gives no error but probe iwlwifi kernel module successfully. To test backport-iwlwifi-dkms packages: 1. Boot the testing kernel from some Intel Wildcat Lake platforms with an Intel AX211 wireless module installed. Here I use Intel WCL-U RVP. 2. Install kernels from corresponding -proposed pocket. 3. The corresponding kernel modules should be built automatically by dpkg triggers. Use `dkms status` to list built kernel versions. 4. Reboot into the same kernel. The dmesg should gives no error but probe iwlwifi kernel module successfully. [Where problems could occur] This changes the way that command object is handled using IWL_HCMD_DFL_NOCOPY to avoid buffer size checking. It doesn't really change runtime behavior or anything else. [Other Info] The patches for backport-iwlwifi-dkms are meant to be superseded by the ones in the master branch, so I did not cherry-pick the one from linux-next instead. Nominate backport-iwlwifi-dkms Resolute and Stonking, because they are versions with WCL support. Nominate linux/{Q,R}, linux-oem-7.0, linux-oem-6.17, because they are either 7.0 kernels or uses backport-iwlwifi-dkms/R. ========== original bug report ========== May 04 13:33:52 ubuntu-202603-38491 kernel: ------------[ cut here ]------------ May 04 13:33:52 ubuntu-202603-38491 kernel: Command UNKNOWN (0xc05) is too large (348 bytes) May 04 13:33:52 ubuntu-202603-38491 kernel: WARNING: CPU: 4 PID: 995 at drivers/net/wireless/intel/iwlwifi/pcie/gen1_2/tx-gen2.c:1278 iwl_pcie_gen2_enqueue_hcmd+0x7ea/0xf10 [iwlwifi] May 04 13:33:52 ubuntu-202603-38491 kernel: Modules linked in: snd_soc_sof_sdw snd_sof_probes snd_soc_intel_hda_dsp_common qrtr snd_soc_rt722_sdca regmap_sdw_mbq snd_hda_codec_intelhdmi snd_soc_dmic bnep snd_hda_intel snd_sof_pci_intel_ptl snd_sof_pci_intel_lnl snd_sof_pci_intel_mtl snd_sof_intel_hda_generic soundwire_intel snd_sof_intel_hda_sdw_bpt snd_sof_intel_hda_common snd_soc_hdac_hda snd_sof_intel_hda_mlink snd_sof_intel_hda snd_hda_codec_hdmi soundwire_cadence snd_sof_pci snd_sof_xtensa_dsp snd_sof snd_sof_utils snd_hda_ext_core snd_hda_codec snd_hda_core snd_intel_dspcfg snd_intel_sdw_acpi snd_soc_acpi_intel_match snd_soc_acpi_intel_sdca_quirks soundwire_generic_allocation snd_soc_sdw_utils snd_soc_acpi snd_hwdep intel_uncore_frequency soundwire_bus intel_uncore_frequency_common snd_soc_sdca x86_pkg_temp_thermal snd_soc_core intel_powerclamp snd_compress coretemp ac97_bus snd_pcm_dmaengine snd_pcm kvm_intel snd_seq_midi dell_pc snd_ctl_led snd_seq_midi_event mei_gsc_proxy intel_rapl_msr binfmt_misc snd_rawmidi kvm xe uvcvideo dell_laptop May 04 13:33:52 ubuntu-202603-38491 kernel: snd_seq irqbypass videobuf2_vmalloc iwlmvm(O) uvc gpu_sched processor_thermal_device_pci videobuf2_memops polyval_clmulni btusb drm_gpuvm ghash_clmulni_intel videobuf2_v4l2 processor_thermal_device btrtl processor_thermal_wt_hint videobuf2_common aesni_intel dell_wmi drm_gpusvm_helper snd_seq_device platform_temperature_control mac80211(O) btintel drm_buddy dell_smbios snd_timer drm_ttm_helper processor_thermal_soc_slider btbcm videodev processor_thermal_rfim ttm btmtk dcdbas nls_iso8859_1 bluetooth libarc4 dell_wmi_ddv dell_wmi_sysman(+) dell_smm_hwmon mc firmware_attributes_class drm_exec iwlwifi(O) processor_thermal_rapl snd intel_rapl_common i2c_i801 processor_thermal_wt_req drm_suballoc_helper dell_wmi_descriptor wmi_bmof i2c_smbus processor_thermal_power_floor soundcore mei_me drm_display_helper processor_thermal_mbox crc8 i2c_mux mei cfg80211(O) cec intel_vpu rc_core iwlwifi_compat(O) intel_pmc_core platform_profile i2c_algo_bit igen6_edac pmt_telemetry int3403_thermal int340x_thermal_zone May 04 13:33:52 ubuntu-202603-38491 kernel: pmt_discovery pmt_class int3400_thermal intel_pmc_ssram_telemetry acpi_thermal_rel intel_vsec acpi_tad intel_hid sparse_keymap acpi_pad joydev input_leds serio_raw mac_hid sch_fq_codel msr parport_pc ppdev lp parport nvme_fabrics efi_pstore nfnetlink dmi_sysfs ip_tables x_tables autofs4 raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq raid1 raid0 linear uas usb_storage ucsi_acpi hid_multitouch typec_ucsi hid_generic typec nvme psmouse video intel_lpss_pci nvme_core e1000e nvme_keyring intel_lpss nvme_auth idma64 thunderbolt i2c_hid_acpi i2c_hid hid wmi pinctrl_intel_platform May 04 13:33:52 ubuntu-202603-38491 kernel: CPU: 4 UID: 0 PID: 995 Comm: NetworkManager Tainted: G O 6.17.0-1020-oem #20-Ubuntu PREEMPT(voluntary) May 04 13:33:52 ubuntu-202603-38491 kernel: Tainted: [O]=OOT_MODULE May 04 13:33:52 ubuntu-202603-38491 kernel: Hardware name: Dell Inc.

The Launchpad report says it happens about 1 in 3 runs. [Fix] Skip the SCANOUT flag and VM_BIND checks for external dma-buf imports in the xe display framebuffer setup and pin paths. For imported sg buffers, CPU caching is controlled by the exporter. The patch keeps the existing checks for local buffers. This patch is from upstream Patchwork, not yet merged: https://patchwork.freedesktop.org/patch/732636/ [Test Plan] Run the fullscreen glxgears test 10 times: $ glxgears -fullscreen Or run the matching checkbox test for the affected GPU: $ checkbox-cli run graphics/2_valid_glxgears_fullscreen_PCI_ID_<affected-gpu> Without patch: screen shows garbage during the fullscreen glxgears test. With patch: fullscreen glxgears completes without screen garbage. [Where problems could occur] Could break external dma-buf framebuffer setup in the xe display driver. If the sg-buffer exception is wrong, imported framebuffers could be accepted when they should be rejected. This could show as display corruption, failed framebuffer creation, or xe framebuffer pinning warnings. [Other Info] SRU target: linux-oem-6.17. The patch is not in an upstream kernel release yet.

Also, since CONFIG_EROFS_FS_ONDEMAND has been removed in Linux 7.2 cycle (https://git.kernel.org/torvalds/c/c37460cd9b2fc). Since CONFIG_EROFS_FS_ONDEMAND conflicts with CONFIG_EROFS_FS_PAGE_CACHE_SHARE due to CONFIG_EROFS_FS_ONDEMAND deprecation at Linux 7.0. I hope CONFIG_EROFS_FS_ONDEMAND can be disabled in Ubuntu 26.10(Stonking Stingray).

Boot to the GDM login screen. 2. Leave the machine idle until the display blanks. 3. The machine subsequently becomes completely unresponsive and requires a hard power-off. Moving the cursor delays both display blanking and the freeze. The issue reproduced repeatedly. The journal ends abruptly without a clean shutdown, OOM, storage, or thermal error. Before one freeze, the kernel repeatedly reported: workqueue: output_poll_execute hogged CPU workqueue: i915_hpd_poll_init_work [i915] hogged CPU Testing: - i915.enable_psr=0 alone did not fix the problem. - i915.enable_psr=0 i915.enable_dc=0 has remained stable during stress testing and display blanking so far. Expected result: The display blanks and wakes normally without affecting the system. Actual result: Display blanking leads to a complete system freeze.
