[PATCH 1/8] arm64: dts: qcom: ipq6018: Disable SS instance in Parkmode for USB

by Krishna Kurapati

For Gen-1 targets like IPQ6018, it is seen that stressing out the controller in host mode results in HC died error: xhci-hcd.12.auto: xHCI host not responding to stop endpoint command xhci-hcd.12.auto: xHCI host controller not responding, assume dead xhci-hcd.12.auto: HC died; cleaning up And at this instant only restarting the host mode fixes it. Disable SuperSpeed instance in park mode for IPQ6018 to mitigate this issue.

[PATCH 20/21] xhci: Apply XHCI_RESET_TO_DEFAULT quirk to TGL

by Mathias Nyman

From: Reka Norman <rekanorman(a)chromium.org> TGL systems have the same issue as ADL, where a large boot firmware delay is seen if USB ports are left in U3 at shutdown. So apply the XHCI_RESET_TO_DEFAULT quirk to TGL as well. The issue it fixes is a ~20s boot time delay when booting from S5. It affects TGL devices, and TGL support was added starting from v5.3.

[PATCH bpf v2 2/2] bpf: Harden __bpf_kfunc tag against linker kfunc removal

by Tony Ambardar

BPF kfuncs are often not directly referenced and may be inadvertently removed by optimization steps during kernel builds, thus the __bpf_kfunc tag mitigates against this removal by including the __used macro. However, this macro alone does not prevent removal during linking, and may still yield build warnings (e.g. on mips64el): LD vmlinux BTFIDS vmlinux WARN: resolve_btfids: unresolved symbol bpf_verify_pkcs7_signature WARN: resolve_btfids: unresolved symbol bpf_lookup_user_key WARN: resolve_btfids: unresolved symbol bpf_lookup_system_key WARN: resolve_btfids: unresolved symbol bpf_key_put WARN: resolve_btfids: unresolved symbol bpf_iter_task_next WARN: resolve_btfids: unresolved symbol bpf_iter_css_task_new WARN: resolve_btfids: unresolved symbol bpf_get_file_xattr WARN: resolve_btfids: unresolved symbol bpf_ct_insert_entry WARN: resolve_btfids: unresolved symbol bpf_cgroup_release WARN: resolve_btfids: unresolved symbol bpf_cgroup_from_id WARN: resolve_btfids: unresolved symbol bpf_cgroup_acquire WARN: resolve_btfids: unresolved symbol bpf_arena_free_pages NM System.map SORTTAB vmlinux OBJCOPY vmlinux.32 Update the __bpf_kfunc tag to better guard against linker optimization by including the new __retain compiler macro, which fixes the warnings above.

[PATCH 3/3] serial: qcom-geni: fix garbage output after buffer flush

The Qualcomm GENI serial driver does not handle buffer flushing and outputs garbage (or NUL) characters for the remainder of any active TX command after the write buffer has been cleared.

[PATCH v2 1/6] ata: libata-scsi: Do not overwrite valid sense data when CK_COND=1

by Igor Pylypiv

Current ata_gen_passthru_sense() code performs two actions: 1. Generates sense data based on the ATA 'status' and ATA 'error' fields. 2. Populates "ATA Status Return sense data descriptor" / "Fixed format sense data" with ATA taskfile fields. The problem is that #1 generates sense data even when a valid sense data is already present (ATA_QCFLAG_SENSE_VALID is set). Factoring out #2 into a separate function allows us to generate sense data only when there is no valid sense data (ATA_QCFLAG_SENSE_VALID is not set). As a bonus, we can now delete a FIXME comment in atapi_qc_complete() which states that we don't want to translate taskfile registers into sense descriptors for ATAPI.
