2020-09-28KVM: x86: Introduce MSR filteringAlexander Graf1-0/+108
It's not desireable to have all MSRs always handled by KVM kernel space. Some MSRs would be useful to handle in user space to either emulate behavior (like uCode updates) or differentiate whether they are valid based on the CPU model. To allow user space to specify which MSRs it wants to see handled by KVM, this patch introduces a new ioctl to push filter rules with bitmaps into KVM. Based on these bitmaps, KVM can then decide whether to reject MSR access. With the addition of KVM_CAP_X86_USER_SPACE_MSR it can also deflect the denied MSR events to user space to operate on. If no filter is populated, MSR handling stays identical to before.

2020-09-28KVM: x86: Allow deflecting unknown MSR accesses to user spaceAlexander Graf1-8/+77
MSRs are weird. Some of them are normal control registers, such as EFER. Some however are registers that really are model specific, not very interesting to virtualization workloads, and not performance critical. Others again are really just windows into package configuration. Out of these MSRs, only the first category is necessary to implement in kernel space. Rarely accessed MSRs, MSRs that should be fine tunes against certain CPU models and MSRs that contain information on the package level are much better suited for user space to process. However, over time we have accumulated a lot of MSRs that are not the first category, but still handled by in-kernel KVM code. This patch adds a generic interface to handle WRMSR and RDMSR from user space. With this, any future MSR that is part of the latter categories can be handled in user space. Furthermore, it allows us to replace the existing "ignore_msrs" logic with something that applies per-VM rather than on the full system. That way you can run productive VMs in parallel to experimental ones where you don't care about proper MSR handling.

2020-09-28soundwire: sysfs: add slave status and device number before probePierre-Louis Bossart1-0/+18
The MIPI DisCo device properties that are read by the driver from platform firmware, or hard-coded in the driver, should only be provided as sysfs entries when a driver probes successfully. However the device status and device number is updated even when there is no driver present, and hence can be updated when a Slave device is detected on the bus without being described in platform firmware and without any driver registered/probed. As suggested by GregKH, the attribute group for Slave status and device number is is added by default upon device registration. Credits to Vinod Koul for the status_show() function, shared in a separate patch and used as is here. The status table was modified to remove an unnecessary enum and status_show() is handled in a different group attribute than what was suggested by Vinod.

The flags: V4L2_SUBDEV_MBUS_CODE_CSC_COLORSPACE, V4L2_SUBDEV_MBUS_CODE_CSC_XFER_FUNC, V4L2_SUBDEV_MBUS_CODE_CSC_YCBCR_ENC/V4L2_SUBDEV_MBUS_CODE_CSC_HSV_ENC V4L2_SUBDEV_MBUS_CODE_CSC_QUANTIZATION are set by the driver in the VIDIOC_SUBDEV_ENUM_MBUS_CODE ioctl. New 'flags' fields were added to the structs v4l2_subdev_mbus_code_enum, v4l2_mbus_framefmt which are borrowed from the 'reserved' field The patch also replaces the 'ycbcr_enc' field in 'struct v4l2_mbus_framefmt' with a union that includes 'hsv_enc' Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-09-26media: v4l2: add support for colorspace conversion API (CSC) for video captureDafna Hirschfeld4-17/+103
For video capture it is the driver that reports the colorspace, transfer function, Y'CbCr/HSV encoding and quantization range used by the video, and there is no way to request something different, even though many HDTV receivers have some sort of colorspace conversion capabilities. For output video this feature already exists since the application specifies this information for the video format it will send out, and the transmitter will enable any available CSC if a format conversion has to be performed in order to match the capabilities of the sink. For video capture we propose adding new v4l2_pix_format flag: V4L2_PIX_FMT_FLAG_SET_CSC. The flag is set by the application, the driver will interpret the colorspace, xfer_func, ycbcr_enc/hsv_enc and quantization fields as the requested colorspace information and will attempt to do the conversion it supports. Drivers set the flags V4L2_FMT_FLAG_CSC_COLORSPACE, V4L2_FMT_FLAG_CSC_XFER_FUNC, V4L2_FMT_FLAG_CSC_YCBCR_ENC/V4L2_FMT_FLAG_CSC_HSV_ENC, V4L2_FMT_FLAG_CSC_QUANTIZATION, in the flags field of the struct v4l2_fmtdesc during enumeration to indicate that they support colorspace conversion for the respective field. Drivers do not have to actually look at the flags. If the flags are not set, then the fields 'colorspace', 'xfer_func', 'ycbcr_enc/hsv_enc', and 'quantization' are set to the default values by the core, i.e. just pass on the received format without conversion.

2020-09-25devlink: introduce flash update overwrite maskJacob Keller1-0/+28
Sections of device flash may contain settings or device identifying information. When performing a flash update, it is generally expected that these settings and identifiers are not overwritten. However, it may sometimes be useful to allow overwriting these fields when performing a flash update. Some examples include, 1) customizing the initial device config on first programming, such as overwriting default device identifying information, or 2) reverting a device configuration to known good state provided in the new firmware image, or 3) in case it is suspected that current firmware logic for managing the preservation of fields during an update is broken. Although some devices are able to completely separate these types of settings and fields into separate components, this is not true for all hardware. To support controlling this behavior, a new DEVLINK_ATTR_FLASH_UPDATE_OVERWRITE_MASK is defined. This is an nla_bitfield32 which will define what subset of fields in a component should be overwritten during an update. If no bits are specified, or of the overwrite mask is not provided, then an update should not overwrite anything, and should maintain the settings and identifiers as they are in the previous image. If the overwrite mask has the DEVLINK_FLASH_OVERWRITE_SETTINGS bit set, then the device should be configured to overwrite any of the settings in the requested component with settings found in the provided image. Similarly, if the DEVLINK_FLASH_OVERWRITE_IDENTIFIERS bit is set, the device should be configured to overwrite any device identifiers in the requested component with the identifiers from the image. Multiple overwrite modes may be combined to indicate that a combination of the set of fields that should be overwritten. Drivers which support the new overwrite mask must set the DEVLINK_SUPPORT_FLASH_UPDATE_OVERWRITE_MASK in the supported_flash_update_params field of their devlink_ops.
