2022-02-11drm/i915: Remove weird code from intel_atomic_check_bigjoiner()Ville Syrjälä1-22/+11
There's some weird junk in intel_atomic_check_bigjoiner() that's trying to look at the old crtc state's bigjoiner usage for some reason. That code is totally unnecessary, and maybe even actively harmful. Not entirely sure which since it's such a mess that I can't actually wrap my brain around what it ends up doing. Either way, thanks to intel_bigjoiner_add_affected_crtcs() all of the old bigjoiner crtcs are guaranteed to be in the state already if any one of them is in the state. Also if any one of those crtcs got flagged for a modeset, then all of them will have been flagged, and the bigjoiner links will have been detached via kill_bigjoiner_slave(). So there is no need to look examing any old bigjoiner usage in intel_atomic_check_bigjoiner(). All we have to care about is whether bigjoiner is needed for the new state, and whether we can get the slave crtc we need.

2022-02-11drm/i915: Fix bigjoiner state copy failsVille Syrjälä1-1/+13
We seem to be missing a few things from the bigjoiner state copy. Namely hw.mode isn't getting copied (which probably causes PIPESRC to be misconfigured), CTM/LUTs aren't getting copied (which could cause the pipe to produced incorrect output), and we also forgot to copy over the color_mgmt_changed flag so potentially we fail to do the actual CTM/LUT programming (assuming we aren't doing a full modeset or fastset).

2022-02-11drm/i915: Flag crtc scaling_filter changes as modesetVille Syrjälä1-0/+4
The core doesn't flag scaling_filter prop changes as needing a modeset. That doesn't work for us since we only reprogram the pipe scaler during full modesets and fastsets. So we need to flag the prop change as a modeset ourselves. Assuming nothing else has changed the operation will get promoted (demoted?) to a fastset later.

This reverts commit 0e8ae5a6ff5952253cd7cc0260df838ab4c21009. 0e8ae5a6ff59 ("PCI/portdrv: Do not setup up IRQs if there are no users") reduced usage of IRQs when we don't think we need them. But Joey, Sergiu, and David reported choppy GUI rendering, systems that became unresponsive every few seconds, incorrect values reported by cpufreq, and high IRQ 16 CPU usage. Joey bisected the issues to 0e8ae5a6ff59, so revert it until we figure out a better solution.

When using USB charging, the AB8500 charger is periodically checking VBAT for a threshold at 3.8V. This crashes badly, as the class_for_each_device() was passed the wrong argument. I think this has maybe worked by chance in the past because of how the structs were arranged but it is leading to crashes now.

The BATCTRL mode reads the temperature of the battery by enabling a certain probing current (7-20 mA) and then measure the voltage of the NTC mounted inside the battery. None of the AB8500 product or the reference designs use this mode. What we use is the so-called BATTEMP mode which enables an internal 230 kOhm pull-up to 1.8 V to the external NTC on pin BatTemp (N16) and then measures the voltage over the NTC using the ADC: 1.8V (VTVOUT) | [ ] 230 kOhm | BatTemp +---------------- ADC Pin N16 | _ |/ [/] NTC _/| | GND Cut out the BATCTRL code to clear the forest and stop maintaining code we can never test. The current inducing method is still used to probe for the battery type using the internal BTI (battery type indicator) on the BatCtrl (C3) pin in a separate code path.

Add a new battery driver for the uPI uG3105 battery monitor. Note the uG3105 is not a full-featured autonomous fuel-gauge. Instead it is expected to be use in combination with some always on microcontroller reading its coulomb-counter before it can wrap (must be read every 400 seconds!). Since Linux does not monitor coulomb-counter changes while the device is off or suspended, the coulomb counter is not used atm. So far this driver is only used on x86/ACPI (non devicetree) devs (also note there is no of_match table). Therefor there is no devicetree bindings documentation for this driver's "upisemi,rsns-microohm" property since this is not used in actual devicetree files and the dt bindings maintainers have requested properties with no actual dt users to _not_ be added to the dt bindings. The property's name has been chosen so that it should not need to be changed if/when devicetree enumeration support gets added later, as it mirrors "maxim,rsns-microohm" from the "maxim,max17042" bindings.

Add support for the I2C Bus Interface on R-Car Gen4 SoCs (e.g. R-Car S4-8) by matching on a family-specific compatible value. While I2C on R-Car Gen4 does support some extra features (Slave Clock Stretch Select), for now it is treated the same as I2C on R-Car Gen3.

2022-02-11drm/cma-helper: Set VM_DONTEXPAND for mmapRobin Murphy1-0/+1
drm_gem_cma_mmap() cannot assume every implementation of dma_mmap_wc() will end up calling remap_pfn_range() (which happens to set the relevant vma flag, among others), so in order to make sure expectations around VM_DONTEXPAND are met, let it explicitly set the flag like most other GEM mmap implementations do. This avoids repeated warnings on a small minority of systems where the display is behind an IOMMU, and has a simple driver which does not override drm_gem_cma_default_funcs. Arm hdlcd is an in-tree affected driver. Out-of-tree, the Apple DCP driver is affected; this fix is required for DCP to be mainlined.

2022-02-11drm/panfrost: Handle IDVS_GROUP_SIZE featureAlyssa Rosenzweig3-0/+7
The IDVS group size feature was missing. It is used on some Bifrost and Valhall GPUs, and is the last kernel-relevant Bifrost feature we're missing. This feature adds an extra IDVS group size field to the JM_CONFIG register. In kbase, the value is configurable via the device tree; kbase uses 0xF as a default if no value is specified. Until we find a device demanding otherwise, let's always set the 0xF default on devices which support this feature mimicking kbase's behaviour. Tuning this register slightly improves performance of index-driven vertex shading. On Mali-G52 (with Mesa), overall glmark2 score is improved from 1026 to 1037. Geometry-heavy scenes like -bshading are improved from 1068 to 1098.

2022-02-11i2c: designware: Add AMD PSP I2C bus supportJan Dabros7-12/+489
Implement an I2C controller sharing mechanism between the host (kernel) and PSP co-processor on some platforms equipped with AMD Cezanne SoC. On these platforms we need to implement "software" i2c arbitration. Default arbitration owner is PSP and kernel asks for acquire as well as inform about release of the i2c bus via mailbox mechanism. +---------+ <- ACQUIRE | | +---------| CPU |\ | | | \ +----------+ SDA | +---------+ \ | |------- MAILBOX +--> | I2C-DW | SCL | +---------+ | |------- | | | +----------+ +---------| PSP | <- ACK | | +---------+ +---------+ <- RELEASE | | +---------| CPU | | | | +----------+ SDA | +---------+ | |------- MAILBOX +--> | I2C-DW | SCL | +---------+ / | |------- | | | / +----------+ +---------| PSP |/ <- ACK | | +---------+ The solution is similar to i2c-designware-baytrail.c implementation, where we are using a generic i2c-designware-* driver with a small "wrapper". In contrary to baytrail semaphore implementation, beside internal acquire_lock() and release_lock() methods we are also applying quirks to lock_bus() and unlock_bus() global adapter methods. With this in place all i2c clients drivers may lock i2c bus for a desired number of i2c transactions (e.g. write-wait-read) without being aware of that such bus is shared with another entity. Modify i2c_dw_probe_lock_support() to select correct semaphore implementation at runtime, since now we have more than one available. Configure new matching ACPI ID "AMDI0019" and register ARBITRATION_SEMAPHORE flag in order to distinguish setup with PSP arbitration. Add myself as a reviewer for I2C DesignWare in order to help with reviewing and testing possible changes touching new i2c-designware-amdpsp.c module.
