2021-03-22media: uapi: Move parsed VP8 pixel format out of stagingEzequiel Garcia1-5/+0
Since we are ready to stabilize the VP8 stateless API, move the parsed VP8 pixel format. Signed-off-by: Ezequiel Garcia <ezequiel@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2021-03-22media: uapi: vp8: Rename v4l2_vp8_loopfilter to v4l2_vp8_loop_filterEzequiel Garcia1-6/+6
Rename to struct v4l2_vp8_loop_filter, which is closer to the VP8 syntax. This change is only cosmetics, but since this API is exposed to userspace, it's worth the trouble to get it consistent.

2021-03-22media: uapi: vp8: Remove "header" from symbol names and macrosEzequiel Garcia2-41/+41
It doesn't seem to add any clarity to have a "header" suffix in controls, struct names and flags. Since this just makes names too long without any benefit, just drop it.

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].

2021-03-11docs: ioctl-number.rst: reserve IIO subsystem ioctl() spaceAlexandru Ardelean1-0/+1
Currently, only the 'i' 0x90 ioctl() actually exists and is defined in 'include/uapi/linux/iio/events.h'. It's the IIO_GET_EVENT_FD_IOCTL, which is used to retrieve and FD for reading events from an IIO device. We will want to add more ioct() numbers, so with this change the 'i' 0x90-0x9F space is reserved for IIO ioctl() calls.

2021-03-11media: buffer.rst: fix a PDF output issueMauro Carvalho Chehab1-4/+4
Sphinx/LaTeX doesn't work well with literal blocks. Due to that, V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF ends being writing outside the table (and even outside the page). We need to not only change the table size and font size, but also to change the message, in order to avoid this bug.

Instead of using "- 1", use "minus one". The reason is that, if the table is split like: V4L2_FWHT_FL_COMPONENTS_NUM_MSK 0x00070000 The number of color components - 1.

While fixing issues with PDF generation, I noticed that bit 8 was missing for WSS 625 format. While here, convert the literal block into a tables, as it becomes more visible. I opted to move the payload into a separate table, as Sphinx has troubles with complex nested tables. This way, it should work fine on both html and LaTeX/PDF formats.

The Cyclades driver was orphaned by commit d459883e6c54 (MAINTAINERS: remove two dead e-mail) 13 years ago. Noone stepped up to take care of them and to fix all the issues the driver has.

2021-02-16cxl/mem: Add basic IOCTL interfaceBen Widawsky1-0/+1
Add a straightforward IOCTL that provides a mechanism for userspace to query the supported memory device commands. CXL commands as they appear to userspace are described as part of the UAPI kerneldoc. The command list returned via this IOCTL will contain the full set of commands that the driver supports, however, some of those commands may not be available for use by userspace. Memory device commands first appear in the CXL 2.0 specification. They are submitted through a mailbox mechanism specified in the CXL 2.0 specification. The send command allows userspace to issue mailbox commands directly to the hardware. The list of available commands to send are the output of the query command. The driver verifies basic properties of the command and possibly inspect the input (or output) payload to determine whether or not the command is allowed (or might taint the kernel).

2021-02-09virt: acrn: Introduce VM management interfacesShuo Liu1-0/+1
The VM management interfaces expose several VM operations to ACRN userspace via ioctls. For example, creating VM, starting VM, destroying VM and so on. The ACRN Hypervisor needs to exchange data with the ACRN userspace during the VM operations. HSM provides VM operation ioctls to the ACRN userspace and communicates with the ACRN Hypervisor for VM operations via hypercalls. HSM maintains a list of User VM. Each User VM will be bound to an existing file descriptor of /dev/acrn_hsm. The User VM will be destroyed when the file descriptor is closed.

2021-01-27bus: fsl-mc: add fsl-mc userspace supportIoana Ciornei1-0/+1
Adding userspace support for the MC (Management Complex) means exporting an ioctl capable device file representing the root resource container. This new functionality in the fsl-mc bus driver intends to provide userspace applications an interface to interact with the MC firmware. Commands that are composed in userspace are sent to the MC firmware through the FSL_MC_SEND_MC_COMMAND ioctl. By default the implicit MC I/O portal is used for this operation, but if the implicit one is busy, a dynamic portal is allocated and then freed upon execution. The command received through the ioctl interface is checked against a known whitelist of accepted MC commands. Commands that attempt a change in hardware configuration will need CAP_NET_ADMIN, while commands used in debugging do not need it.

The gdth driver refers to a SCSI parallel, PCI-only HBA RAID adapter which was manufactured by the now-defunct ICP Vortex company, later acquired by Adaptec and superseded by the aacraid series of controllers. The driver itself would require a major overhaul before any modifications can be attempted, but seeing that it's unlikely to have any users left it should rather be removed completely.

2021-01-07platform/surface: Add Surface Aggregator user-space interfaceMaximilian Luz1-0/+2
Add a misc-device providing user-space access to the Surface Aggregator EC, mainly intended for debugging, testing, and reverse-engineering. This interface gives user-space applications the ability to send requests to the EC and receive the corresponding responses. The device-file is managed by a pseudo platform-device and corresponding driver to avoid dependence on the dedicated bus, allowing it to be loaded in a minimal configuration. A python library and scripts to access this device can be found at [1].

2020-12-30Documentation: Add documentation for new platform_profile sysfs attributeMark Pearson2-0/+43
On modern systems the platform performance, temperature, fan and other hardware related characteristics are often dynamically configurable. The profile is often automatically adjusted to the load by some automatic-mechanism (which may very well live outside the kernel). These auto platform-adjustment mechanisms often can be configured with one of several 'platform-profiles', with either a bias towards low-power consumption or towards performance (and higher power consumption and thermals). Introduce a new platform_profile sysfs API which offers a generic API for selecting the performance-profile of these automatic-mechanisms.
