2023-04-12media: Use designated initializers for all subdev pad opsLaurent Pinchart
Structures passed to subdev pad operations are all zero-initialized when declaring variables. In most cases, this is done with designated initializers to initialize some of the fields to specific values, but in a minority of cases the structures are zero-initialized by assigning them to '{ 0 }' or '{ }'. Improve coding style consistency by using designated initializers where possible, always initializing the 'which' field.

2023-04-12media: Prefer designated initializers over memset for subdev pad opsLaurent Pinchart
Structures passed to subdev pad operations are all zero-initialized, but not always with the same kind of code constructs. While most drivers used designated initializers, which zero all the fields that are not specified, when declaring variables, some use memset(). Those two methods lead to the same end result, and, depending on compiler optimizations, may even be completely equivalent, but they're not consistent. Improve coding style consistency by using designated initializers instead of calling memset(). Where applicable, also move the variables to inner scopes of for loops to ensure correct initialization in all iterations.

2023-04-12media: Zero-initialize all structures passed to subdev pad operationsLaurent Pinchart
Several drivers call subdev pad operations, passing structures that are not fully zeroed. While the drivers initialize the fields they care about explicitly, this results in reserved fields having uninitialized values. Future kernel API changes that make use of those fields thus risk breaking proper driver operation in ways that could be hard to detect. To avoid this, make the code more robust by zero-initializing all the structures passed to subdev pad operation. Maintain a consistent coding style by preferring designated initializers (which zero-initialize all the fields that are not specified) over memset() where possible, and make variable declarations local to inner scopes where applicable. One notable exception to this rule is in the ipu3 driver, where a memset() is needed as the structure is not a local variable but a function parameter provided by the caller. Not all fields of those structures can be initialized when declaring the variables, as the values for those fields are computed later in the code. Initialize the 'which' field in all cases, and other fields when the variable declaration is so close to the v4l2_subdev_call() call that it keeps all the context easily visible when reading the code, to avoid hindering readability.

2023-04-12media: venus: dec: Fix capture formats enumeration orderJavier Martinez Canillas
Commit 9593126dae3e ("media: venus: Add a handling of QC08C compressed format") and commit cef92b14e653 ("media: venus: Add a handling of QC10C compressed format") added support for the QC08C and QC10C compressed formats respectively. But these also caused a regression, because the new formats where added at the beginning of the vdec_formats[] array and the vdec_inst_init() function sets the default format output and capture using fixed indexes of that array: static void vdec_inst_init(struct venus_inst *inst) { ... inst->fmt_out = &vdec_formats[8]; inst->fmt_cap = &vdec_formats[0]; ... } Since now V4L2_PIX_FMT_NV12 is not the first entry in the array anymore, the default capture format is not set to that as it was done before. Both commits changed the first index to keep inst->fmt_out default format set to V4L2_PIX_FMT_H264, but did not update the latter to keep .fmt_out default format set to V4L2_PIX_FMT_NV12. Rather than updating the index to the current V4L2_PIX_FMT_NV12 position, let's reorder the entries so that this format is the first entry again. This would also make VIDIOC_ENUM_FMT report the V4L2_PIX_FMT_NV12 format with an index 0 as it did before the QC08C and QC10C formats were added.

2023-04-11media: vsp1: Replace vb2_is_streaming() with vb2_start_streaming_called()Laurent Pinchart
The vsp1 driver uses the vb2_is_streaming() function in its .buf_queue() handler to check if the .start_streaming() operation has been called, and decide whether to just add the buffer to an internal queue, or also trigger a hardware run. vb2_is_streaming() relies on the vb2_queue structure's streaming field, which used to be set only after calling the .start_streaming() operation. Commit a10b21532574 ("media: vb2: add (un)prepare_streaming queue ops") changed this, setting the .streaming field in vb2_core_streamon() before enqueuing buffers to the driver and calling .start_streaming(). This broke the vsp1 driver which now believes that .start_streaming() has been called when it hasn't, leading to a crash: [ 881.058705] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020 [ 881.067495] Mem abort info: [ 881.070290] ESR = 0x0000000096000006 [ 881.074042] EC = 0x25: DABT (current EL), IL = 32 bits [ 881.079358] SET = 0, FnV = 0 [ 881.082414] EA = 0, S1PTW = 0 [ 881.085558] FSC = 0x06: level 2 translation fault [ 881.090439] Data abort info: [ 881.093320] ISV = 0, ISS = 0x00000006 [ 881.097157] CM = 0, WnR = 0 [ 881.100126] user pgtable: 4k pages, 48-bit VAs, pgdp=000000004fa51000 [ 881.106573] [0000000000000020] pgd=080000004f36e003, p4d=080000004f36e003, pud=080000004f7ec003, pmd=0000000000000000 [ 881.117217] Internal error: Oops: 0000000096000006 [#1] PREEMPT SMP [ 881.123494] Modules linked in: rcar_fdp1 v4l2_mem2mem [ 881.128572] CPU: 0 PID: 1271 Comm: yavta Tainted: G B 6.2.0-rc1-00023-g6c94e2e99343 #556 [ 881.138061] Hardware name: Renesas Salvator-X 2nd version board based on r8a77965 (DT) [ 881.145981] pstate: 400000c5 (nZcv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 881.152951] pc : vsp1_dl_list_add_body+0xa8/0xe0 [ 881.157580] lr : vsp1_dl_list_add_body+0x34/0xe0 [ 881.162206] sp : ffff80000c267710 [ 881.165522] x29: ffff80000c267710 x28: ffff000010938ae8 x27: ffff000013a8dd98 [ 881.172683] x26: ffff000010938098 x25: ffff000013a8dc00 x24: ffff000010ed6ba8 [ 881.179841] x23: ffff00000faa4000 x22: 0000000000000000 x21: 0000000000000020 [ 881.186998] x20: ffff00000faa4000 x19: 0000000000000000 x18: 0000000000000000 [ 881.194154] x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000000 [ 881.201309] x14: 0000000000000000 x13: 746e696174206c65 x12: ffff70000157043d [ 881.208465] x11: 1ffff0000157043c x10: ffff70000157043c x9 : dfff800000000000 [ 881.215622] x8 : ffff80000ab821e7 x7 : 00008ffffea8fbc4 x6 : 0000000000000001 [ 881.222779] x5 : ffff80000ab821e0 x4 : ffff70000157043d x3 : 0000000000000020 [ 881.229936] x2 : 0000000000000020 x1 : ffff00000e4f6400 x0 : 0000000000000000 [ 881.237092] Call trace: [ 881.239542] vsp1_dl_list_add_body+0xa8/0xe0 [ 881.243822] vsp1_video_pipeline_run+0x270/0x2a0 [ 881.248449] vsp1_video_buffer_queue+0x1c0/0x1d0 [ 881.253076] __enqueue_in_driver+0xbc/0x260 [ 881.257269] vb2_start_streaming+0x48/0x200 [ 881.261461] vb2_core_streamon+0x13c/0x280 [ 881.265565] vb2_streamon+0x3c/0x90 [ 881.269064] vsp1_video_streamon+0x2fc/0x3e0 [ 881.273344] v4l_streamon+0x50/0x70 [ 881.276844] __video_do_ioctl+0x2bc/0x5d0 [ 881.280861] video_usercopy+0x2a8/0xc80 [ 881.284704] video_ioctl2+0x20/0x40 [ 881.288201] v4l2_ioctl+0xa4/0xc0 [ 881.291525] __arm64_sys_ioctl+0xe8/0x110 [ 881.295543] invoke_syscall+0x68/0x190 [ 881.299303] el0_svc_common.constprop.0+0x88/0x170 [ 881.304105] do_el0_svc+0x4c/0xf0 [ 881.307430] el0_svc+0x4c/0xa0 [ 881.310494] el0t_64_sync_handler+0xbc/0x140 [ 881.314773] el0t_64_sync+0x190/0x194 [ 881.318450] Code: d50323bf d65f03c0 91008263 f9800071 (885f7c60) [ 881.324551] ---[ end trace 0000000000000000 ]--- [ 881.329173] note: yavta[1271] exited with preempt_count 1 A different regression report sent to the linux-media mailing list ([1]) was answered with a claim that the vb2_is_streaming() function has never been meant for this purpose.

2023-04-11media: platform: mtk-mdp3: decompose hardware-related information in shared ↵Moudy Ho
memory The communication between the MDP3 kernel driver and SCP is to pass a shared memory through the cooperation of "mtk-mdp3-vpu.c" and remoteproc driver. The data structure of this shared memory is defined in "mtk-img-ipi.h", as shown below: vpu->work_addr -> +-----------------------------------------+ | | | To SCP : Input frame parameters | | (struct img_ipi_frameparam) | | | vpu->pool -> +-----------------------------------------+ | | | From SCP : Output component config pool | | (struct img_config) | | | | *struct img_config 1 | | | | | | | | v | | *struct img_config N | | (N = MDP_CONFIG_POOL_SIZE) | +-----------------------------------------+ One output component configuration contains the components currently used by the pipeline, and has the register settings that each component needs to set. Since the quantity, type and function of components on each chip will vary, the effect is that the size of the "struct img_config" and its substructures will be different on each chip. In addition, all chips will have to update their SCP firmware for every change if the output component config structure is defined and shared by a common header. Therefore, all functions that operate on "struct img_config" and its substructures must be separated by chips and so are the relevant definations.

2023-04-11media: camss: sm8250: Pipeline starting and stopping for multiple virtual ↵Milen Mitkov
channels Use the multistream series function video_device_pipeline_alloc_start to allows multiple clients of the same pipeline. If the VFE entity is used by another instance of the pipeline, the pipeline won't be stopped. This allows for stopping and starting streams at any point without disrupting the other running streams. To prepare and start multiple virtual channels each CSID source pad corresponding to a virtual channel must be linked to the corresponding IFE entity. CSID pad 1 (1st source pad) corresponds to virtual channel 0, CSID pad 2 corresponds to virtual channel 1 and so on. Each of these must be linked to corresponding IFE RDI port. E.g. to enable vc 0 on CSID0: media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]' To enable vc1 on CSID0: media-ctl -l '"msm_csid0":2->"msm_vfe0_rdi1":0[1]' And so on. Note that on SM8250 each CSID is connected, at the hardware level, to only one IFE. Thus, you must link CSID0 with IFE0, you can't link it with IFE1. Example: the following media controller setup expects multiplexed sensor data on CSIPHY2. Data will be passed on to CSID0, which will demux it to 2 streams - for RDI0 and RD1 ports of IFE0: media-ctl -v -d /dev/media0 -V '"imx577 '22-001a'":0[fmt:SRGGB10/3840x2160 field:none]' media-ctl -V '"msm_csiphy2":0[fmt:SRGGB10/3840x2160]' media-ctl -V '"msm_csid0":0[fmt:SRGGB10/3840x2160]' media-ctl -V '"msm_csid0":1[fmt:SRGGB10/3840x2160]' media-ctl -V '"msm_csid0":2[fmt:SRGGB10/3840x2160]' media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/3840x2160]' media-ctl -V '"msm_vfe0_rdi1":0[fmt:SRGGB10/3840x2160]' media-ctl -l '"msm_csiphy2":1->"msm_csid0":0[1]' media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]' media-ctl -l '"msm_csid0":2->"msm_vfe0_rdi1":0[1]' Note: CSID's entity pad 0 is a sink pad, pads 1..4 are source pads To start streaming a v4l2 client must open the corresponding /dev/videoN node. For example, with yavta: yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 3840x2160 -F /dev/video0 yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 3840x2160 -F /dev/video1 Note that IFEs (vfe0, vfe1) on SM8250 have 3 RDI ports and a single PIX port and IFELites (vfe2, vfe3) have 4 RDI ports and no PIX port.

2023-04-11media: camss: sm8250: Virtual channels for CSIDMilen Mitkov
CSID hardware on SM8250 can demux up to 4 simultaneous streams based on virtual channel (vc) or datatype (dt). The CSID subdevice entity now has 4 source ports that can be enabled/disabled and thus can control which virtual channels are enabled. Datatype demuxing not tested. In order to keep a valid internal state of the subdevice, implicit format propagation from the sink to the source pads has been preserved. However, the format on each source pad can be different and in that case it must be configured explicitly. CSID's s_stream is called when any stream is started or stopped. It will call configure_streams() that will rewrite IRQ settings to HW. When multiple streams are running simultaneously there is an issue when writing IRQ settings for one stream while another is still running, thus avoid re-writing settings if they were not changed in link setup, or by fully powering off the CSID hardware.
