Document that it is possible to provide defaults for multiple bus types to v4l2_fwnode_endpoint_parse and v4l2_fwnode_endpoint_alloc_parse. Also underline the fact that detecting the bus type without bus-type property is only for the old drivers. Also correct capitalisation of BT.656.

The bus specific parameters were a union. This made providing bus specific defaults impossible as the memory used to store the defaults for multiple different busses was the same.

2020-09-10media: v4l2-async: Document asd allocation requirementsLaurent Pinchart1-2/+3
The v4l2_async_notifier_add_subdev() function requires the asd pointer it receives to be allocated dynamically, but doesn't explicitly say so. Only one driver out of 13 get its right (atmel-sama5d2-isc.c, but with memory leaks in the error paths), clearly showing we have an issue. Update the v4l2_async_notifier_add_subdev() documentation to clearly state the allocation requirement. Whether this will be enough to avoid new offending code isn't certain, but it's a good first step nonetheless.

Merge emailed patches from Peter Xu: "This is a small series that I picked up from Linus's suggestion to simplify cow handling (and also make it more strict) by checking against page refcounts rather than mapcounts. This makes uffd-wp work again (verified by running upmapsort)" Note: this is horrendously bad timing, and making this kind of fundamental vm change after -rc3 is not at all how things should work. The saving grace is that it really is a a nice simplification: 8 files changed, 29 insertions(+), 120 deletions(-) The reason for the bad timing is that it turns out that commit 17839856fd58 ("gup: document and work around 'COW can break either way' issue" broke not just UFFD functionality (as Peter noticed), but Mikulas Patocka also reports that it caused issues for strace when running in a DAX environment with ext4 on a persistent memory setup. And we can't just revert that commit without re-introducing the original issue that is a potential security hole, so making COW stricter (and in the process much simpler) is a step to then undoing the forced COW that broke other uses.

2020-09-04xen: add helpers to allocate unpopulated memoryRoger Pau Monne1-0/+9
To be used in order to create foreign mappings. This is based on the ZONE_DEVICE facility which is used by persistent memory devices in order to create struct pages and kernel virtual mappings for the IOMEM areas of such devices. Note that on kernels without support for ZONE_DEVICE Xen will fallback to use ballooned pages in order to create foreign mappings. The newly added helpers use the same parameters as the existing {alloc/free}_xenballooned_pages functions, which allows for in-place replacement of the callers. Once a memory region has been added to be used as scratch mapping space it will no longer be released, and pages returned are kept in a linked list. This allows to have a buffer of pages and prevents resorting to frequent additions and removals of regions. If enabled (because ZONE_DEVICE is supported) the usage of the new functionality untangles Xen balloon and RAM hotplug from the usage of unpopulated physical memory ranges to map foreign pages, which is the correct thing to do in order to avoid mappings of foreign pages depend on memory hotplug. Note the driver is currently not enabled on Arm platforms because it would interfere with the identity mapping required on some platforms.

2020-09-03media: rc: harmonize infrared durations to microsecondsSean Young1-6/+5
rc-core kapi uses nanoseconds for infrared durations for receiving, and microseconds for sending. The uapi already uses microseconds for both, so this patch does not change the uapi. Infrared durations do not need nanosecond resolution. IR protocols do not have durations shorter than about 100 microseconds. Some IR hardware offers 250 microseconds resolution, which is sufficient for most protocols. Better hardware has 50 microsecond resolution and is enough for every protocol I am aware off. Unify on microseconds everywhere. This simplifies the code since less conversion between microseconds and nanoseconds needs to be done.

2020-09-02libata: implement ATA_HORKAGE_MAX_TRIM_128M and apply to SandisksTejun Heo1-0/+1
All three generations of Sandisk SSDs lock up hard intermittently. Experiments showed that disabling NCQ lowered the failure rate significantly and the kernel has been disabling NCQ for some models of SD7's and 8's, which is obviously undesirable. Karthik worked with Sandisk to root cause the hard lockups to trim commands larger than 128M. This patch implements ATA_HORKAGE_MAX_TRIM_128M which limits max trim size to 128M and applies it to all three generations of Sandisk SSDs.

2020-09-02drm/i915: Fix sha_text population codeSean Paul1-0/+3
This patch fixes a few bugs: 1- We weren't taking into account sha_leftovers when adding multiple ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with the beginning of ksv[j] 2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was being placed on the wrong half of sha_text, overlapping the leftover ksv value 3- In the sha_leftovers == 2 case, we need to manually terminate the byte stream with 0x80 since the hardware doesn't have enough room to add it after writing M0 The upside is that all of the HDCP supported HDMI repeaters I could find on Amazon just strip HDCP anyways, so it turns out to be _really_ hard to hit any of these cases without an MST hub, which is not (yet) supported. Oh, and the sha_leftovers == 1 case works perfectly!

Applications are expected to fill V4L2_CID_MPEG_VIDEO_H264_SCALING_MATRIX if a non-flat scaling matrix applies to the picture. This is the case if SPS scaling_matrix_present_flag or PPS pic_scaling_matrix_present_flag are set, and should be handled by applications. On one hand, the PPS bitstream syntax element signals the presence of a Picture scaling matrix modifying the Sequence (SPS) scaling matrix. On the other hand, our flag should indicate if the scaling matrix V4L2 control is applicable to this request. Rename the flag from PPS_FLAG_PIC_SCALING_MATRIX_PRESENT to PPS_FLAG_SCALING_MATRIX_PRESENT, to avoid mixing this flag with bitstream syntax element pic_scaling_matrix_present_flag, and clarify the meaning of our flag.

2020-09-01media: uapi: h264: Clean slice invariants syntax elementsEzequiel Garcia2-20/+20
The H.264 specification requires in section 7.4.3 "Slice header semantics", that the following values shall be the same in all slice headers: pic_parameter_set_id frame_num field_pic_flag bottom_field_flag idr_pic_id pic_order_cnt_lsb delta_pic_order_cnt_bottom delta_pic_order_cnt[ 0 ] delta_pic_order_cnt[ 1 ] sp_for_switch_flag slice_group_change_cycle These bitstream fields are part of the slice header, and therefore passed redundantly on each slice. The purpose of the redundancy is to make the codec fault-tolerant in network scenarios. This is of course not needed to be reflected in the V4L2 controls, given the bitstream has already been parsed by applications. Therefore, move the redundant fields to the per-frame decode parameters control (DECODE_PARAMS). Field 'pic_parameter_set_id' is simply removed in this case, because the PPS control must currently contain the active PPS. Syntax elements dec_ref_pic_marking() and those related to pic order count, remain invariant as well, and therefore, the fields dec_ref_pic_marking_bit_size and pic_order_cnt_bit_size are also common to all slices.

2020-09-01media: uapi: h264: Clarify SLICE_BASED modeEzequiel Garcia1-4/+0
Currently, the SLICE_BASED and FRAME_BASED modes documentation is misleading and not matching the intended use-cases. Drop non-required fields SLICE_PARAMS 'start_byte_offset' and DECODE_PARAMS 'num_slices' and clarify the decoding modes in the documentation. On SLICE_BASED mode, a single slice is expected per OUTPUT buffer, and therefore 'start_byte_offset' is not needed (since the offset to the slice is the start of the buffer). This mode requires the use of CAPTURE buffer holding, and so the number of slices shall not be required. On FRAME_BASED mode, the devices are expected to take care of slice parsing. Neither SLICE_PARAMS are required (and shouldn't be exposed by frame-based drivers), nor the number of slices.

Although unlikely, a 8192x4320 video (where macroblocks are 16x16), would contain 138240 macroblocks on a frame. As per the H264 specification, 'first_mb_in_slice' can be up to PicSizeInMbs - 1, so increase the size of the field to 32-bits. Note that v4l2_ctrl_h264_slice_params struct will be modified in a follow-up commit, and so we defer its 64-bit padding.

As specified in section 7.3.3 Slice header syntax, the prediction weight table is present if: ((weighted_pred_flag && (slice_type == P || slice_type == SP)) || \ (weighted_bipred_idc == 1 && slice_type == B)) Given its size, it makes sense to move this table to its control, so applications can avoid passing it if the slice doesn't specify it. Before this change struct v4l2_ctrl_h264_slice_params was 960 bytes. With this change, it's 188 bytes and struct v4l2_ctrl_h264_pred_weight is 772 bytes.

When calling into hid_map_usage(), the passed event code is blindly stored as is, even if it doesn't fit in the associated bitmap. This event code can come from a variety of sources, including devices masquerading as input devices, only a bit more "programmable". Instead of taking the event code at face value, check that it actually fits the corresponding bitmap, and if it doesn't: - spit out a warning so that we know which device is acting up - NULLify the bitmap pointer so that we catch unexpected uses Code paths that can make use of untrusted inputs can now check that the mapping was indeed correct and bail out if not.
