2022-01-27interconnect: qcom: rpm: Prevent integer overflow in rateStephan Gerhold1-0/+1
[ Upstream commit a7d9436a6c85fcb8843c910fd323dcd7f839bf63 ] Using icc-rpm on ARM32 currently results in clk_set_rate() errors during boot, e.g. "bus clk_set_rate error: -22". This is very similar to commit 7381e27b1e56 ("interconnect: qcom: msm8974: Prevent integer overflow in rate") where the u64 is converted to a signed long during clock rate rounding, resulting in an overflow on 32-bit platforms. Let's fix it similarly by making sure that the rate does not exceed LONG_MAX. Such high clock rates will surely result in the maximum frequency of the bus anyway.

2021-08-12Revert "interconnect: qcom: icc-rpmh: Add BCMs to commit list in pre_aggregate"Georgi Djakov1-5/+5
This reverts commit f84f5b6f72e68bbaeb850b58ac167e4a3a47532a, which is causing regressions on some platforms, preventing them to boot or do a clean reboot. This is because the above commit is sending also all the zero bandwidth requests to turn off any resources that might be enabled unnecessarily, but currently this may turn off interconnects that are enabled by default, but with no consumer to keep them on. Let's revert this for now as some platforms are not ready for such change yet. In the future we can introduce some _ignore_unused option that could keep also the unused resources on platforms that have only partial interconnect support and also add .shutdown callbacks to deal with disabling the resources in the right order.

2021-08-09interconnect: qcom: osm-l3: Use driver-specific namingBjorn Andersson1-23/+23
In situations were the developer screws up by e.g. not giving the OSM nodes unique identifiers the interconnect framework might mix up nodes between the OSM L3 provider and e.g. the RPMh provider. The resulting callstack contains "qcom_icc_set", which is not unique to the OSM L3 provider driver. Once the faulting qcom_icc_set() is identified it's further confusing that "qcom_icc_node" is different between the different drivers. To avoid this confusion, rename the node struct and the setter in the OSM L3 driver to include "osm_l3" in their names.

2021-07-30interconnect: qcom: icc-rpmh: Add BCMs to commit list in pre_aggregateMike Tipton1-5/+5
We're only adding BCMs to the commit list in aggregate(), but there are cases where pre_aggregate() is called without subsequently calling aggregate(). In particular, in icc_sync_state() when a node with initial BW has zero requests. Since BCMs aren't added to the commit list in these cases, we don't actually send the zero BW request to HW. So the resources remain on unnecessarily. Add BCMs to the commit list in pre_aggregate() instead, which is always called even when there are no requests.

2021-07-30interconnect: qcom: icc-rpmh: Ensure floor BW is enforced for all nodesMike Tipton1-7/+5
We currently only enforce BW floors for a subset of nodes in a path. All BCMs that need updating are queued in the pre_aggregate/aggregate phase. The first set() commits all queued BCMs and subsequent set() calls short-circuit without committing anything. Since the floor BW isn't set in sum_avg/max_peak until set(), then some BCMs are committed before their associated nodes reflect the floor. Set the floor as each node is being aggregated. This ensures that all all relevant floors are set before the BCMs are committed.

list_sort() internally casts the comparison function passed to it to a different type with constant struct list_head pointers, and uses this pointer to call the functions, which trips indirect call Control-Flow Integrity (CFI) checking. Instead of removing the consts, this change defines the list_cmp_func_t type and changes the comparison function types of all list_sort() callers to use const pointers, thus avoiding type mismatches.

This patch series adds the SDM660 interconnect provider driver in order to stop some timeouts and achieve some decent performance by avoiding to be NoC limited. It's also providing some power consumption improvement, but I have only measured that as less heat, which is quite important when working on thermally constrained devices like smartphones. Please note that this driver's yaml binding is referring to a MMCC clock, so this series does depend on the SDM660 MMCC driver that I have sent separately. The multimedia clock is required only for the Multimedia NoC (mnoc).

Using an incorrect indexes will also result error for the consumers when they try to find a valid path between the endpoints. Let's fix this and use the correct ids.

Introduce a driver for the Qualcomm interconnect busses found in the SDM630/SDM636/SDM660 SoCs. The topology consists of several NoCs that are controlled by a remote processor that collects the aggregated bandwidth for each master-slave pairs. On a note, these chips are managing the "bus QoS" in a "hybrid" fashion: some of the paths in the topology are managed through (and by, of course) the RPM uC, while some others are "AP Owned", meaning that the AP shall do direct writes to the appropriate QoS registers for the specific paths and ports, instead of sending an indication to the RPM and leaving the job to that one.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM device tree updates from Arnd Bergmann: "Across all platforms, there is a continued move towards DT schema for validating the dts files. As a result there are bug fixes for mistakes that are found using these schema, in addition to warnings from the dtc compiler. As usual, many changes are for adding support for additional on-chip and on-board components in the machines we already support. The newly supported SoCs for this release are: - MStar Infinity2M, a low-end IP camera chip based on a dual-core Cortex-A7, otherwise similar to the Infinity chip we already support. This is also known as the SigmaStar SSD202D, and we add support for the Honestar ssd201htv2 development kit. - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller (BMC), in the same family as the NPCM750. This gets used in the Ampere Altra based "Fii Kudo" server and the Quanta GSJ, both of which are added as well. - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own Brahma-B53 CPU. Support is also added for the Asus ROG Rapture GT-AC5300 high-end WiFi router based on this chip. - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores, meant for faster Chromebooks and tablets. It gets added along with its reference design. - Mediatek MT6779 (Helio P90) is a high-end phone chip from last year's generation, also added along with its reference board. This one is still based on Cortex-A75/A55. - Mediatek MT8167 is a version of the already supported MT8516 chip, both based on Cortex-A35. It gets added along with the "Pumpkin" single board computer, but is likely to also make its way into low-end tablets in the future. For the already supported chips, there are a number of new boards. Interestingly there are more 32-bit machines added this time than 64-bit. Here is a brief list of the new boards: - Three new Mikrotik router variants based on Marvell Prestera 98DX3236, a close relative of the more common Armada XP - A reference board for the Marvell Armada 382 - Three new servers using ASpeed baseboard management controllers, the actual machines being from Bytedance, Facebook and IBM, and one machine using the Nuvoton NPCM750 BMC. - The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412. - The usual set of 32-bit i.MX industrial/embedded hardware: * Protonic WD3 (tractor e-cockpit) * Kamstrup OMNIA Flex Concentrator (smart grid platform) * Van der Laan LANMCU (food storage) * Altesco I6P (vehicle inspection stations) * PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard - DH electronics STM32MP157C DHCOM, a PicoITX carrier board for the aleady supported DHCOM module - Three new Allwinner SoC based single-board computers: * NanoPi R1 (H3 based) * FriendlyArm ZeroPi (H3 based) * Elimo Initium SBC (S3 based) - Ouya Game Console based on Nvidia Tegra 3 - Version 5 of the already supported Zynq Z-Turn MYIR Board - LX2162AQDS, a reference platform for NXP Layerscape LX2162A, which is a repackaged 16-core LX2160A - A series of Kontron i.MX8M Mini baseboard/SoM versions - Espressobin Ultra, a new variant of the popular Armada 3700 based board, - IEI Puzzle-M801, a rackmount network appliance based on Marvell Armada 8040 - Microsoft Lumia 950 XL, a phone - HDK855 and HDK865 Hardware development kits for Qualcomm sm8250 and sm8150, respectively - Three new board variants of the "Trogdor" Chromebook (sc7180) - New board variants of the Renesas based "Kingfisher" and "HiHope" reference boards - Kobol Helios64, an open source NAS appliance based on Rockchips RK3399 - Engicam PX30.Core, a SoM based on Rockchip PX30, along with a few carrier boards" * tag 'arm-soc-dt-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (679 commits) arm64: dts: sparx5: Add SGPIO devices arm64: dts: sparx5: Add reset support dt-bindings: gpio: Add a binding header for the MSC313 GPIO driver ARM: mstar: SMP support ARM: mstar: Wire up smpctrl for SSD201/SSD202D ARM: mstar: Add smp ctrl registers to infinity2m dtsi ARM: mstar: Add dts for Honestar ssd201htv2 ARM: mstar: Add chip level dtsi for SSD202D ARM: mstar: Add common dtsi for SSD201/SSD202D ARM: mstar: Add infinity2m support dt-bindings: mstar: Add Honestar SSD201_HT_V2 to mstar boards dt-bindings: vendor-prefixes: Add honestar vendor prefix dt-bindings: mstar: Add binding details for mstar,smpctrl ARM: mstar: Fill in GPIO controller properties for infinity ARM: mstar: Add gpio controller to MStar base dtsi ARM: zynq: Fix incorrect reference to XM013 instead of XM011 ARM: zynq: Convert at25 binding to new description on zc770-xm013 ARM: zynq: Fix OCM mapping to be aligned with binding on zc702 ARM: zynq: Fix leds subnode name for zc702/zybo-z7 ARM: zynq: Rename bus to be align with simple-bus yaml ...

Additionally PRNG and RTC is enabled. Similarly for SM8150, the ARM SMMU could be added which allows the secondary USB controller and PHYs, as well as WiFi to be added and support for the SM8150 HDK board to be introduced. Additionally Coresight and support for the last-level cache controller was added. MSM8916 finally has VDDCX and VDDMX removed as regulators and are now handled by the rpmpd driver for the devices controlling them. The Longsheer L8150 gains touchscreen, sensors, vibrator and LED support. MSM8992 gains USB and SDHCI support as well as an I2C controller and the associated RMI4 based touchscreen for the Lumia 950. MSM8994 also gains USB and SDHCI support, as well as VADC and temp-alarm support. Then support for the Lumia 950 XL is added. SDM845 gains interconnect properties for a number of devices and the GENI wrappers gains iommu stream configuration, which means DMA operations on e.g. I2C now works. The Lenovo Yoga C630 finally has the SMMU enabled, a few fixes and the description of the eDP bridge and panel means that the laptop can now boot mainline with working display, GPU, WiFi and audio.

2020-11-30interconnect: Add generic interconnect driver for Exynos SoCsSylwester Nawrocki5-0/+218
This patch adds a generic interconnect driver for Exynos SoCs in order to provide interconnect functionality for each "samsung,exynos-bus" compatible device. The SoC topology is a graph (or more specifically, a tree) and its edges are described by specifying in the 'interconnects' property the interconnect consumer path for each interconnect provider DT node. Each bus is now an interconnect provider and an interconnect node as well (cf. Documentation/interconnect/interconnect.rst), i.e. every bus registers itself as a node. Node IDs are not hard coded but rather assigned dynamically at runtime. This approach allows for using this driver with various Exynos SoCs. Frequencies requested via the interconnect API for a given node are propagated to devfreq using dev_pm_qos_update_request(). Please note that it is not an error when CONFIG_INTERCONNECT is 'n', in which case all interconnect API functions are no-op. The samsung,data-clk-ratio DT property is used to specify the ratio of the interconect bandwidth to the minimum data clock frequency for each bus. Due to unspecified relative probing order, -EPROBE_DEFER may be propagated to ensure that the parent is probed before its children.
