This includes * adding error messages where there was none * converting over dev_err/dev_warn * removing the top-level error message after mtk_cpu_dvfs_info_init() is called, since every error path inside that function already logs the error reason.

2024-07-09cpufreq: Add Loongson-3 CPUFreq driver supportHuacai Chen4-0/+409
Some of LoongArch processors (Loongson-3 series) support DVFS, their IOCSR.FEATURES has IOCSRF_FREQSCALE set. And they has a micro-core in the package called SMC (System Management Controller), which can be used to detect temperature, control fans, scale frequency and voltage, etc. The Loongson-3 CPUFreq driver is very simple now, it communicate with SMC, get DVFS info, set target frequency from CPUFreq core, and so on. There is a command list to interact with SMC, widely-used commands in the CPUFreq driver include: CMD_GET_VERSION: Get SMC firmware version. CMD_GET_FEATURE: Get enabled SMC features. CMD_SET_FEATURE: Enable SMC features, such as basic DVFS, BOOST. CMD_GET_FREQ_LEVEL_NUM: Get the number of all frequency levels. CMD_GET_FREQ_BOOST_LEVEL: Get the first boost frequency level. CMD_GET_FREQ_LEVEL_INFO: Get the detail info of a frequency level. CMD_GET_FREQ_INFO: Get the current frequency. CMD_SET_FREQ_INFO: Set the target frequency. In future we will add automatic frequency scaling, which is similar to Intel's HWP (HardWare P-State).

2024-07-08sched_ext: Implement DSQ iteratorTejun Heo3-2/+196
DSQs are very opaque in the consumption path. The BPF scheduler has no way of knowing which tasks are being considered and which is picked. This patch adds BPF DSQ iterator. - Allows iterating tasks queued on a DSQ in the dispatch order or reverse from anywhere using bpf_for_each(scx_dsq) or calling the iterator kfuncs directly. - Has ordering guarantee where only tasks which were already queued when the iteration started are visible and consumable during the iteration. v5: - Add a comment to the naked list_empty(&dsq->list) test in consume_dispatch_q() to explain the reasoning behind the lockless test and by extension why nldsq_next_task() isn't used there. - scx_qmap changes separated into its own patch. v4: - bpf_iter_scx_dsq_new() declaration in common.bpf.h was using the wrong type for the last argument (bool rev instead of u64 flags). Fix it. v3: - Alexei pointed out that the iterator is too big to allocate on stack. Added a prep patch to reduce the size of the cursor. Now bpf_iter_scx_dsq is 48 bytes and bpf_iter_scx_dsq_kern is 40 bytes on 64bit. - u32_before() comparison factored out. v2: - scx_bpf_consume_task() is separated out into a separate patch. - DSQ seq and iter flags don't need to be u64. Use u32. Signed-off-by: Tejun Heo <[email protected]> Reviewed-by: David Vernet <[email protected]> Acked-by: Alexei Starovoitov <[email protected]> Cc: [email protected]
2024-07-08sched_ext: Take out ->priq and ->flags from scx_dsq_nodeTejun Heo3-33/+33
struct scx_dsq_node contains two data structure nodes to link the containing task to a DSQ and a flags field that is protected by the lock of the associated DSQ. One reason why they are grouped into a struct is to use the type independently as a cursor node when iterating tasks on a DSQ. However, when iterating, the cursor only needs to be linked on the FIFO list and the rb_node part ends up inflating the size of the iterator data structure unnecessarily making it potentially too expensive to place it on stack. Take ->priq and ->flags out of scx_dsq_node and put them in sched_ext_entity as ->dsq_priq and ->dsq_flags, respectively. scx_dsq_node is renamed to scx_dsq_list_node and the field names are renamed accordingly. This will help implementing DSQ task iterator that can be allocated on stack. No functional change intended.

2024-07-08PCI: of_property: Add interrupt-controller property in PCI device nodesHerve Codina1-0/+24
PCI devices and bridges DT nodes created during the PCI scan are created with the interrupt-map property set to handle interrupts. In order to set this interrupt-map property at a specific level, a phandle to the parent interrupt controller is needed. On systems that are not fully described by a device-tree, the parent interrupt controller may be unavailable (i.e. not described by the device-tree). As mentioned in the [1], avoiding the use of the interrupt-map property and considering a PCI device as an interrupt controller itself avoid the use of a parent interrupt phandle. In that case, the PCI device itself as an interrupt controller is responsible for routing the interrupts described in the device-tree world (DT overlay) to the PCI interrupts. Add the 'interrupt-controller' property in the PCI device DT node.

The reference i2c-controller.yaml already defines 'address-cells' and 'size-cells', so drop them from list of properties. Drop them as well from required properties, even though i2c-controller.yaml does not require them, because I2C controller could be enabled without any children in DTS for user-space usage.

2024-07-09i2c: omap: wakeup the controller during suspend() callbackThomas Richard1-0/+22
A device may need the controller up during suspend_noirq() or resume_noirq(). But if the controller is autosuspended, there is no way to wakeup it during suspend_noirq() or resume_noirq() because runtime pm is disabled at this time. The suspend() callback wakes up the controller, so it is available until its suspend_noirq() callback (pm_runtime_force_suspend()). During the resume, it's restored by resume_noirq() callback (pm_runtime_force_resume()). Then resume() callback enables autosuspend. So the controller is up during a little time slot in suspend and resume sequences even if it's not used.

2024-07-09i2c: omap: switch to NOIRQ_SYSTEM_SLEEP_PM_OPS() and RUNTIME_PM_OPS()Thomas Richard1-7/+7
Replace SET_NOIRQ_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS() by NOIRQ_SYSTEM_SLEEP_PM_OPS() and RUNTIME_PM_OPS(). The usage of pm_ptr() and these more recent macros allows the compiler to see and drop the dead code. The unnecessary '__maybe_unused' annotations on PM functions can be removed.
