2022-07-15media: videodev2.h: add V4L2_CTRL_FLAG_DYNAMIC_ARRAYHans Verkuil1-0/+1
Add a new flag that indicates that this control is a dynamically sized array. Also document this flag. Currently dynamically sized arrays are limited to one dimensional arrays, but that might change in the future if there is a need for it. The initial use-case of dynamic arrays are stateless codecs. A frame can be divided in many slices, so you want to provide an array containing slice information for each slice. Typically the number of slices is small, but the standard allow for hundreds or thousands of slices. Dynamic arrays are a good solution since sizing the array for the worst case would waste substantial amounts of memory.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v5.20 This is a big release thus far and there will probably be more changes to come, it's a combination of a larger than usual crop of new drivers and some subsysetm wide cleanups from Charles rather than anything structural. The SOF and Intel DSP code both also continue to be very actively developed. - Restructing of the set_fmt() callbacks to be specified in terms of the device rather than with semantics depending on if the device is supposed to be a CODEC or SoC, making things clearer in situations like CODEC to CODEC links. - Clean up of the way we flag which DAI naming scheme we use to reflect the progress that's been made modernising things. - Merge of more of the Intel AVS driver stack, including some board integrations. - New version 4 mechanism for communication with SOF DSPs. - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms. - Improvements for CODEC to CODEC support in the generic cards. - Support for AMD Jadeite and various machines, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780.

2022-07-14ublk_drv: support to complete io command via task_work_addMing Lei1-0/+6
Use task_work_add if it is available, since task_work_add can bring up better performance, especially batching signaling ->ubq_daemon can be done. It is observed that task_work_add() can boost iops by +4% on random 4k io test. Also except for completing io command, all other code paths are same with completing io command via io_uring_cmd_complete_in_task. Meantime add one flag of UBLK_F_URING_CMD_COMP_IN_TASK for comparing the mode easily.

2022-07-14ublk_drv: add io_uring based userspace block driverMing Lei1-0/+156
This is the driver part of userspace block driver(ublk driver), the other part is userspace daemon part(ublksrv)[1]. The two parts communicate by io_uring's IORING_OP_URING_CMD with one shared cmd buffer for storing io command, and the buffer is read only for ublksrv, each io command is indexed by io request tag directly, and is written by ublk driver. For example, when one READ io request is submitted to ublk block driver, ublk driver stores the io command into cmd buffer first, then completes one IORING_OP_URING_CMD for notifying ublksrv, and the URING_CMD is issued to ublk driver beforehand by ublksrv for getting notification of any new io request, and each URING_CMD is associated with one io request by tag. After ublksrv gets the io command, it translates and handles the ublk io request, such as, for the ublk-loop target, ublksrv translates the request into same request on another file or disk, like the kernel loop block driver. In ublksrv's implementation, the io is still handled by io_uring, and share same ring with IORING_OP_URING_CMD command. When the target io request is done, the same IORING_OP_URING_CMD is issued to ublk driver for both committing io request result and getting future notification of new io request. Another thing done by ublk driver is to copy data between kernel io request and ublksrv's io buffer: 1) before ubsrv handles WRITE request, copy the request's data into ublksrv's userspace io buffer, so that ublksrv can handle the write request 2) after ubsrv handles READ request, copy ublksrv's userspace io buffer into this READ request, then ublk driver can complete the READ request Zero copy may be switched if mm is ready to support it. ublk driver doesn't handle any logic of the specific user space driver, so it is small/simple enough.

2022-07-14kvm: stats: tell userspace which values are booleanPaolo Bonzini1-0/+1
Some of the statistics values exported by KVM are always only 0 or 1. It can be useful to export this fact to userspace so that it can track them specially (for example by polling the value every now and then to compute a % of time spent in a specific state). Therefore, add "boolean value" as a new "unit". While it is not exactly a unit, it walks and quacks like one. In particular, using the type would be wrong because boolean values could be instantaneous or peak values (e.g. "is the rmap allocated?") or even two-bucket histograms (e.g. "number of posted vs. non-posted interrupt injections").

commit dd374f84baec ("wifi: nl80211: expose link ID for associated BSSes") used a top-level attribute to send link ID of the associated BSS in the nested attribute NL80211_ATTR_BSS. But since NL80211_ATTR_BSS is a nested attribute of the attributes defined in enum nl80211_bss, define a new attribute in enum nl80211_bss and use it for sending the link ID of the BSS.

2022-07-11vfio-pci/zdev: add function handle to clp base capabilityMatthew Rosato1-0/+3
The function handle is a system-wide unique identifier for a zPCI device. With zPCI instruction interpretation, the host will no longer be executing the zPCI instructions on behalf of the guest. As a result, the guest needs to use the real function handle in order for firmware to associate the instruction with the proper PCI function. Let's provide that handle to the guest.

2022-07-09drm/fourcc: Add DRM_FORMAT_D[1248]Geert Uytterhoeven1-0/+12
As Rn covers single-channel formats with a direct relationship between channel value and brightness, and Cn can be any colors, there are currently no fourcc codes to describe single-channel formats with an inverse relationship between channel value and brightness. Introduce fourcc codes for a single-channel frame buffer format with two, four, sixteen, or 256 brightness ("darkness") levels, where there is an inverse relationship between channel value and brightness. As the number of bits per pixel may be less than eight, some of these formats rely on proper block handling for the calculation of bits per pixel and pitch. The fill order (the order in which multiple pixels are packed in a byte) is the same order as used for grayscale (2, 4, and 16 levels) images in the PNG specification, Version 1.2. This order is also the recommended and default order (FillOrder = 1) for bilevel and grayscale (16 levels) images in the TIFF 6.0 Specification, and is also used for monochrome images in the PBM file format, monochrome Linux frame buffer logos, and BDF and PSF (Linux kernel) font files.

2022-07-09Input: document the units for resolution of size axesSiarhei Vishniakou1-4/+7
Today, the resolution of size axes is not documented. As a result, it's not clear what the canonical interpretation of this value should be. On Android, there is a need to calculate the size of the touch ellipse in physical units (millimeters). After reviewing linux source, it turned out that most of the existing usages are already interpreting this value as "units/mm". This documentation will make it explicit. This will help device implementations with correctly following the linux specs, and will ensure that the devices will work on Android without needing further customized parameters for scaling of major/minor values.
