2024-09-04x86/sched: Add basic support for CPU capacity scalingRafael J. Wysocki2-2/+100
In order be able to compute the sizes of tasks consistently across all CPUs in a hybrid system, it is necessary to provide CPU capacity scaling information to the scheduler via arch_scale_cpu_capacity(). Moreover, the value returned by arch_scale_freq_capacity() for the given CPU must correspond to the arch_scale_cpu_capacity() return value for it, or utilization computations will be inaccurate. Add support for it through per-CPU variables holding the capacity and maximum-to-base frequency ratio (times SCHED_CAPACITY_SCALE) that will be returned by arch_scale_cpu_capacity() and used by scale_freq_tick() to compute arch_freq_scale for the current CPU, respectively. In order to avoid adding measurable overhead for non-hybrid x86 systems, which are the vast majority in the field, whether or not the new hybrid CPU capacity scaling will be in effect is controlled by a static key. This static key is set by calling arch_enable_hybrid_capacity_scale() which also allocates memory for the per-CPU data and initializes it. Next, arch_set_cpu_capacity() is used to set the per-CPU variables mentioned above for each CPU and arch_rebuild_sched_domains() needs to be called for the scheduler to realize that capacity-aware scheduling can be used going forward.

2024-09-04arm64: dts: imx8m: update spdif sound card node propertiesElinor Montmasson3-11/+43
The merge of imx-spdif driver into fsl-asoc-card brought new DT properties that can be used with the "fsl,imx-audio-spdif" compatible: * The "spdif-controller" property from imx-spdif is named "audio-cpu" in fsl-asoc-card. * fsl-asoc-card uses codecs explicitly declared in DT with "audio-codec". With an S/PDIF, codec drivers spdif_transmitter and spdif_receiver should be used. Driver imx-spdif used instead the dummy codec and a pair of boolean properties, "spdif-in" and "spdif-out". While backward compatibility is kept to support properties "spdif-controller", "spdif-in" and "spdif-out", using new properties has several benefits: * "audio-cpu" and "audio-codec" are more generic names reflecting that the fsl-asoc-card driver supports multiple hardware. They are properties already used by devices using the fsl-asoc-card driver. They are also similar to properties of simple-card: "cpu" and "codec". * "spdif-in" and "spdif-out" imply the use of the dummy codec in the driver. However, there are already two codec drivers for the S/PDIF, spdif_transmitter and spdif_receiver. It is better to declare S/PDIF Tx and Rx devices in a DT, and then reference them with "audio-codec" than using the dummy codec. For those reasons, this commit updates in-tree DTs to use the new properties: * Rename "spdif-controller" property to "audio-cpu". * Declare S/PDIF transmitter and/or receiver devices, and use them with the "audio-codec" property instead of "spdif-out" and/or "spdif-in". These modifications were tested only on an imx8mn-evk board. Note that out-of-tree and old DTs are still supported.

2024-09-04arm64: dts: freescale: imx93-tqma9352: set SION for cmd and data pad of USDHCMarkus Niebel3-29/+34
imx93 pad integrate has one issue, refer to ERR052021: ERR052021 uSDHC: Sometimes uSDHC does not work under VDD_SOC low drive mode and nominal mode Description: uSDHC PADs have one integration issue. When CMD/DATA lines direction change from output to input, uSDHC controller begin sampling, the integration issue will make input enable signal from uSDHC propagated to the PAD with a long delay, thus the new input value on the pad comes to uSDHC lately. The uSDHC sampled the old input value and the sampling result is wrong. Workaround: Set uSDHC CMD/DATA PADs iomux register SION bit to 1, then PADs will propagate input to uSDHC with no delay, so correct value is sampled. This issue will wrongly trigger the start bit when sample the USDHC command response, cause the USDHC trigger command CRC/index/endbit error, which will finally impact the tuning pass window, espically will impact the standard tuning logic, and can't find a correct delay cell to get the best timing.
