2021-03-18iommu/dma: Resurrect the "forcedac" optionRobin Murphy1-7/+8
In converting intel-iommu over to the common IOMMU DMA ops, it quietly lost the functionality of its "forcedac" option. Since this is a handy thing both for testing and for performance optimisation on certain platforms, reimplement it under the common IOMMU parameter namespace. For the sake of fixing the inadvertent breakage of the Intel-specific parameter, remove the dmar_forcedac remnants and hook it up as an alias while documenting the transition to the new common parameter.

Add documentation for the user-space interface of the Surface DTX (detachment system) driver, used on Microsoft Surface Book series devices. Signed-off-by: Maximilian Luz <luzmaximilian@gmail.com> Link: https://lore.kernel.org/r/20210308184819.437438-4-luzmaximilian@gmail.com Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2021-03-17platform/surface: Add DTX driverMaximilian Luz1-0/+2
The Microsoft Surface Book series devices consist of a so-called clipboard part (containing the CPU, touchscreen, and primary battery) and a base part (containing keyboard, secondary battery, and optional discrete GPU). These parts can be separated, i.e. the clipboard can be detached and used as tablet. This detachment process is initiated by pressing a button. On the Surface Book 2 and 3 (targeted with this commit), the Surface Aggregator Module (i.e. the embedded controller on those devices) attempts to send a notification to any listening client driver and waits for further instructions (i.e. whether the detachment process should continue or be aborted). If it does not receive a response in a certain time-frame, the detachment process (by default) continues and the clipboard can be physically separated. In other words, (by default and) without a driver, the detachment process takes about 10 seconds to complete. This commit introduces a driver for this detachment system (called DTX). This driver allows a user-space daemon to control and influence the detachment behavior. Specifically, it forwards any detachment requests to user-space, allows user-space to make such requests itself, and allows handling of those requests. Requests can be handled by either aborting, continuing/allowing, or delaying (i.e. resetting the timeout via a heartbeat commend). The user-space API is implemented via the /dev/surface/dtx miscdevice. In addition, user-space can change the default behavior on timeout from allowing detachment to disallowing it, which is useful if the (optional) discrete GPU is in use. Furthermore, this driver allows user-space to receive notifications about the state of the base, specifically when it is physically removed (as opposed to detachment requested), in what manner it is connected (i.e. in reverse-/tent-/studio- or laptop-mode), and what type of base is connected. Based on this information, the driver also provides a simple tablet-mode switch (aliasing all modes without keyboard access, i.e. tablet-mode and studio-mode to its reported tablet-mode). An implementation of such a user-space daemon, allowing configuration of detachment behavior via scripts (e.g. safely unmounting USB devices connected to the base before continuing) can be found at [1].

2021-03-16kbuild: Enable DT undocumented compatible checksRob Herring1-0/+3
dt-validate has an option to warn on any compatible strings which don't match any schema. The option has recently been improved to fix false positives, so let's enable the option. This is useful for tracking compatibles which are undocumented or not yet converted to DT schema. Previously, the only check of undocumented compatible strings has been an imperfect checkpatch.pl check. The option is enabled by default for 'dtbs_check'. This will add more warnings, but some platforms are down to only a handful of these warnings (good job!). There's about 100 cases in the binding examples, so the option is disabled until these are fixed. In the meantime, they can be checked with: make DT_CHECKER_FLAGS=-m dt_binding_check Cc: Maxime Ripard <mripard@kernel.org> Cc: Masahiro Yamada <masahiroy@kernel.org> Cc: Michal Marek <michal.lkml@markovi.net> Cc: linux-kbuild@vger.kernel.org Signed-off-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/20210311233640.1581526-2-robh@kernel.org

2021-03-15Documentation/features: mark BATCHED_UNMAP_TLB_FLUSH doesn't apply to ARM64Barry Song2-1/+2
BATCHED_UNMAP_TLB_FLUSH is used on x86 to do batched tlb shootdown by sending one IPI to TLB flush all entries after unmapping pages rather than sending an IPI to flush each individual entry. On arm64, tlb shootdown is done by hardware. Flush instructions are innershareable. The local flushes are limited to the boot (1 per CPU) and when a task is getting a new ASID. So marking this feature as "TODO" is not proper. ".." isn't good as well. So this patch adds a "N/A" for this kind of features which are not needed on some architectures.

There's several dependencies in dtschema since v2020.8.1 we need, so let's bump the version required to v2021.2.1. Specifically, the graph.yaml schema and improved undocumented compatible check are needed.
