2022-11-22bus: ixp4xx: Don't touch bit 7 on IXP42xLinus Walleij
We face some regressions on a few IXP42x systems when accessing flash, the following unrelated error prints appear from the PCI driver: ixp4xx-pci c0000000.pci: PCI: abort_handler addr = 0xff9ffb5f, isr = 0x0, status = 0x22a0 ixp4xx-pci c0000000.pci: imprecise abort (...) It turns out that while bit 7 is masked "reserved" it is not unused, so masking it off as zero is dangerous, and breaks flash access on some systems such as the NSLU2. Be more careful and avoid masking off any of the reserved bits 7, 8, 9 or 30. Only keep masking EXP_WORD (bit 2) on IXP43x which is necessary in some setups.

2022-11-22fs: do not update freeing inode i_io_listSvyatoslav Feldsherov
After commit cbfecb927f42 ("fs: record I_DIRTY_TIME even if inode already has I_DIRTY_INODE") writeback_single_inode can push inode with I_DIRTY_TIME set to b_dirty_time list. In case of freeing inode with I_DIRTY_TIME set this can happen after deletion of inode from i_io_list at evict. Stack trace is following. evict fat_evict_inode fat_truncate_blocks fat_flush_inodes writeback_inode sync_inode_metadata(inode, sync=0) writeback_single_inode(inode, wbc) <- wbc->sync_mode == WB_SYNC_NONE This will lead to use after free in flusher thread. Similar issue can be triggered if writeback_single_inode in the stack trace update inode->i_io_list. Add explicit check to avoid it.

2022-11-22Documentation: add amd-pstate kernel command line optionsPerry Yuan
Add a new amd pstate driver command line option to enable driver passive working mode via MSR and shared memory interface to request desired performance within abstract scale and the power management firmware (SMU) convert the perf requests into actual hardware pstates. Also the `disable` parameter can disable the pstate driver loading by adding `amd_pstate=disable` to kernel command line. Acked-by: Huang Rui <ray.huang@amd.com> Reviewed-by: Gautham R.

2022-11-22cpufreq: amd-pstate: add amd-pstate driver parameter for mode selectionPerry Yuan
When the amd_pstate driver is built-in users still need a method to be able enable or disable it depending upon their circumstance. Add support for an early parameter to do this. There is some performance degradation on a number of ASICs in the passive mode. This performance issue was originally discovered in shared memory systems but it has been proven that certain workloads on MSR systems also suffer performance issues. Set the amd-pstate driver as disabled by default to temporarily mitigate the performance problem. 1) with `amd_pstate=disable`, pstate driver will be disabled to load at kernel booting. 2) with `amd_pstate=passive`, pstate driver will be enabled and loaded as non-autonomous working mode supported in the low-level power management firmware. 3) If neither parameter is specified, the driver will be disabled by default to avoid triggering performance regressions in certain ASICs Acked-by: Huang Rui <ray.huang@amd.com> Reviewed-by: Gautham R.

2022-11-22cpufreq: amd-pstate: cpufreq: amd-pstate: reset MSR_AMD_PERF_CTL register at ↵Wyes Karny
init MSR_AMD_PERF_CTL is guaranteed to be 0 on a cold boot. However, on a kexec boot, for instance, it may have a non-zero value (if the cpu was in a non-P0 Pstate). In such cases, the cores with non-P0 Pstates at boot will never be pushed to P0, let alone boost frequencies. Kexec is a common workflow for reboot on Linux and this creates a regression in performance. Fix it by explicitly setting the MSR_AMD_PERF_CTL to 0 during amd_pstate driver init.

2022-11-22extcon: usbc-tusb320: Update state on probe even if no IRQ pendingMarek Vasut
Currently this driver triggers extcon and typec state update in its probe function, to read out current state reported by the chip and report the correct state to upper layers. This synchronization is performed correctly, but only in case the chip indicates a pending interrupt in reg09 register. This fails to cover the situation where all interrupts reported by the chip were already handled by Linux before reboot, then the system rebooted, and then Linux starts again. In this case, the TUSB320 no longer reports any interrupts in reg09, and the state update does not perform any update as it depends on that interrupt indication. Fix this by turning tusb320_irq_handler() into a thin wrapper around tusb320_state_update_handler(), where the later now contains the bulk of the code of tusb320_irq_handler(), but adds new function parameter "force_update". The "force_update" parameter can be used by the probe function to assure that the state synchronization is always performed, independent of the interrupt indicated in reg09. The interrupt handler tusb320_irq_handler() callback uses force_update=false to avoid state updates on potential spurious interrupts and retain current behavior.

Probe for omap2430 glue layer is now broken for interrupt resources in all cases. Commit 239071064732 ("partially Revert "usb: musb: Set the DT node on the child device"") broke probing for SoCs using ti-sysc interconnect target module as the dt node is not found. Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core") caused omap3 to fail with error "-ENXIO: IRQ mc not found" as the IRQ resources are no longer automatically populated from devicetree. Let's fix the issues by calling device_set_of_node_from_dev() only if the SoC has been updated to probe with ti-sysc. And for legacy SoCs, let's populate the resources manually as needed. Note that once we have updated the SoCs to probe with proper devicetree data in all cases, this is no longer needed. But doing that requires patching both devicetree and SoC code, so let's fix the probe issues first.

The kernel robot reports a link failure when activating the FOTG210 host subdriver with =y on a system where the USB host core is a module (CONFIG_USB=m). This is a bit of special case, so mimic the Kconfig incantations from DWC3: let the subdrivers for host or peripheral depend on the host or gadget support being =y or the same as the FOTG210 core itself. This should ensure that either: - The host (CONFIG_USB) or gadget (CONFIG_GADGET) is compiled in and then the FOTG210 can be either module or compiled in. - The host or gadget is modular, and then the FOTG210 module must be a module too, or we cannot resolve the symbols at link time.
