Setting it to largest possible value lets DMA-mapping API always create contiguous mappings in DMA address space. This is essential for all devices, which use dma-contig videobuf2 memory allocator and shared buffers. Till now, the only case when vb2-dma-contig really 'worked' was a case where userspace provided USERPTR buffer, which was in fact mmaped contiguous buffer from the other v4l2/drm device. Also DMABUF made of contiguous buffer worked only when its exporter did not split it into several chunks in the scatter-list. Any other buffer failed, regardless of the arch/platform used and the presence of the IOMMU of the device bus. This patch provides interface to fix this issue.

MFC firmware is limited and it cannot use the default configuration. If IOMMU is available, the patch disables the default DMA address space configuration and creates a new address space of size limited to 256M and base address set to 0x20000000. For now the same address space is shared by both 'left' and 'right' memory channels, because the DMA/IOMMU frameworks do not support configuring them separately. This is not optimal, but besides limiting total address space available has no other drawbacks (MFC firmware supports 256M of address space per each channel).

So a set of VIDIOC_REQBUFS ioctl calls will be made with count 0 and then the real VIDIOC_REQBUFS call with count == n. But for count 0, the driver not only frees the buffer but also closes the MFC instance and s5p_mfc_ctx state is set to MFCINST_FREE. The VIDIOC_REQBUFS handler for the output device checks if the s5p_mfc_ctx state is set to MFCINST_INIT (which happens on an VIDIOC_S_FMT) and fails otherwise. So after a VIDIOC_REQBUFS(n), future VIDIOC_REQBUFS(n) calls will fails unless a VIDIOC_S_FMT ioctl calls happens before the reqbufs. But applications may first set the format and then attempt to determine the I/O methods supported by the driver (for example Gstramer does it) so the state won't be set to MFCINST_INIT again and VIDIOC_REQBUFS will fail. To avoid this issue, only free the buffers on VIDIOC_REQBUFS(0) but don't close the MFC instance to allow future VIDIOC_REQBUFS(n) calls to succeed.

for a pointer to struct media_devnode. However, inside media-devnode.[ch], "mdev" is used to represent a pointer to struct media_devnode. This is very confusing and may lead to development errors. So, let's change all occurrences at media-devnode.[ch] to also use "devnode" for such pointers. This patch doesn't make any functional changes.

While this works fine during normal usage, it leads to a race condition during devnode unregister. the problem is that drivers assume that, after calling media_device_unregister(), the struct that contains media_device can be freed. This is not true, as it can't be freed until userspace closes all opened /dev/media devnodes. In other words, if the media devnode is still open, and media_device gets freed, any call to an ioctl will make the core to try to access struct media_device, with will cause an use-after-free and even GPF. Fix this by dynamically allocating the struct media_devnode and only freeing it when it is safe.

Add devnode struct device kobj as the cdev parent kobject. cdev_add() gets a reference to it and releases it in cdev_del() ensuring that the devnode is not deallocated as long as the application has the device file open. media_devnode_register() initializes the struct device kobj before calling cdev_add(). media_devnode_unregister() does cdev_del() and then deletes the device. devnode is released when the last reference to the struct device is gone.

The number of planes is specific to a buffer, not to the queue. This does lead to the situation where multi-plane buffers may be requested and queued with n planes, but VIDIOC_DQBUF IOCTL may be passed an argument struct with fewer planes. __fill_v4l2_buffer() however uses the number of planes from the dequeued videobuf2 buffer, overwriting kernel memory (the m.planes array allocated in video_usercopy() in v4l2-ioctl.c) if the user provided fewer planes than the dequeued buffer had.

It is designed to handle a multiple types of hardware (receivers, +transmitters, USB dongles). The framework also gives the option to decide +what to do in the kernel driver and what should be handled by userspace +applications. In addition it integrates the remote control passthrough +feature into the kernel's remote control framework. + + +The CEC Protocol +---------------- + +The CEC protocol enables consumer electronic devices to communicate with each +other through the HDMI connection. The protocol uses logical addresses in the +communication. The logical address is strictly connected with the functionality +provided by the device. The TV acting as the communication hub is always +assigned address 0. The physical address is determined by the physical +connection between devices. + +The CEC framework described here is up to date with the CEC 2.0 specification. +It is documented in the HDMI 1.4 specification with the new 2.0 bits documented +in the HDMI 2.0 specification. But for most of the features the freely available +HDMI 1.3a specification is sufficient: + +http://www.microprocessor.org/HDMISpecification13a.pdf + + +The Kernel Interface +==================== + +CEC Adapter +----------- + +The struct cec_adapter represents the CEC adapter hardware. It is created by +calling cec_allocate_adapter() and deleted by calling cec_delete_adapter(): + +struct cec_adapter *cec_allocate_adapter(const struct cec_adap_ops *ops, + void *priv, const char *name, u32 caps, u8 available_las, + struct device *parent); +void cec_delete_adapter(struct cec_adapter *adap); + +To create an adapter you need to pass the following information: + +ops: adapter operations which are called by the CEC framework and that you +have to implement. + +priv: will be stored in adap->priv and can be used by the adapter ops. + +name: the name of the CEC adapter. Note: this name will be copied. + +caps: capabilities of the CEC adapter. These capabilities determine the + capabilities of the hardware and which parts are to be handled + by userspace and which parts are handled by kernelspace. The + capabilities are returned by CEC_ADAP_G_CAPS. + +available_las: the number of simultaneous logical addresses that this + adapter can handle. Must be 1 <= available_las <= CEC_MAX_LOG_ADDRS. + +parent: the parent device. + + +To register the /dev/cecX device node and the remote control device (if +CEC_CAP_RC is set) you call: + +int cec_register_adapter(struct cec_adapter *adap); + +To unregister the devices call: + +void cec_unregister_adapter(struct cec_adapter *adap); + +Note: if cec_register_adapter() fails, then call cec_delete_adapter() to +clean up. But if cec_register_adapter() succeeded, then only call +cec_unregister_adapter() to clean up, never cec_delete_adapter(). The +unregister function will delete the adapter automatically once the last user +of that /dev/cecX device has closed its file handle. + + +Implementing the Low-Level CEC Adapter +-------------------------------------- + +The following low-level adapter operations have to be implemented in +your driver: + +struct cec_adap_ops { + /* Low-level callbacks */ + int (*adap_enable)(struct cec_adapter *adap, bool enable); + int (*adap_monitor_all_enable)(struct cec_adapter *adap, bool enable); + int (*adap_log_addr)(struct cec_adapter *adap, u8 logical_addr); + int (*adap_transmit)(struct cec_adapter *adap, u8 attempts, + u32 signal_free_time, struct cec_msg *msg); + void (*adap_log_status)(struct cec_adapter *adap); + + /* High-level callbacks */ + ... +}; + +The three low-level ops deal with various aspects of controlling the CEC adapter +hardware: + + +To enable/disable the hardware: + + int (*adap_enable)(struct cec_adapter *adap, bool enable); + +This callback enables or disables the CEC hardware. Enabling the CEC hardware +means powering it up in a state where no logical addresses are claimed. This +op assumes that the physical address (adap->phys_addr) is valid when enable is +true and will not change while the CEC adapter remains enabled. The initial +state of the CEC adapter after calling cec_allocate_adapter() is disabled. + +Note that adap_enable must return 0 if enable is false. + + +To enable/disable the 'monitor all' mode: + + int (*adap_monitor_all_enable)(struct cec_adapter *adap, bool enable); + +If enabled, then the adapter should be put in a mode to also monitor messages +that not for us. Not all hardware supports this and this function is only +called if the CEC_CAP_MONITOR_ALL capability is set. This callback is optional +(some hardware may always be in 'monitor all' mode). + +Note that adap_monitor_all_enable must return 0 if enable is false. + + +To program a new logical address: + + int (*adap_log_addr)(struct cec_adapter *adap, u8 logical_addr); + +If logical_addr == CEC_LOG_ADDR_INVALID then all programmed logical addresses +are to be erased. Otherwise the given logical address should be programmed. +If the maximum number of available logical addresses is exceeded, then it +should return -ENXIO. Once a logical address is programmed the CEC hardware +can receive directed messages to that address. + +Note that adap_log_addr must return 0 if logical_addr is CEC_LOG_ADDR_INVALID. + + +To transmit a new message: + + int (*adap_transmit)(struct cec_adapter *adap, u8 attempts, + u32 signal_free_time, struct cec_msg *msg); + +This transmits a new message. The attempts argument is the suggested number of +attempts for the transmit. + +The signal_free_time is the number of data bit periods that the adapter should +wait when the line is free before attempting to send a message. This value +depends on whether this transmit is a retry, a message from a new initiator or +a new message for the same initiator. Most hardware will handle this +automatically, but in some cases this information is needed. + +The CEC_FREE_TIME_TO_USEC macro can be used to convert signal_free_time to +microseconds (one data bit period is 2.4 ms). + + +To log the current CEC hardware status: + + void (*adap_status)(struct cec_adapter *adap, struct seq_file *file); + +This optional callback can be used to show the status of the CEC hardware. +The status is available through debugfs: cat /sys/kernel/debug/cec/cecX/status + + +Your adapter driver will also have to react to events (typically interrupt +driven) by calling into the framework in the following situations: + +When a transmit finished (successfully or otherwise): + +void cec_transmit_done(struct cec_adapter *adap, u8 status, u8 arb_lost_cnt, + u8 nack_cnt, u8 low_drive_cnt, u8 error_cnt); + +The status can be one of: + +CEC_TX_STATUS_OK: the transmit was successful. +CEC_TX_STATUS_ARB_LOST: arbitration was lost: another CEC initiator +took control of the CEC line and you lost the arbitration. +CEC_TX_STATUS_NACK: the message was nacked (for a directed message) or +acked (for a broadcast message). A retransmission is needed. +CEC_TX_STATUS_LOW_DRIVE: low drive was detected on the CEC bus. This +indicates that a follower detected an error on the bus and requested a +retransmission. +CEC_TX_STATUS_ERROR: some unspecified error occurred: this can be one of +the previous two if the hardware cannot differentiate or something else +entirely. +CEC_TX_STATUS_MAX_RETRIES: could not transmit the message after +trying multiple times. Should only be set by the driver if it has hardware +support for retrying messages. If set, then the framework assumes that it +doesn't have to make another attempt to transmit the message since the +hardware did that already. + +The *_cnt arguments are the number of error conditions that were seen. +This may be 0 if no information is available. Drivers that do not support +hardware retry can just set the counter corresponding to the transmit error +to 1, if the hardware does support retry then either set these counters to +0 if the hardware provides no feedback of which errors occurred and how many +times, or fill in the correct values as reported by the hardware. + +When a CEC message was received: + +void cec_received_msg(struct cec_adapter *adap, struct cec_msg *msg); + +Speaks for itself. + +Implementing the High-Level CEC Adapter +--------------------------------------- + +The low-level operations drive the hardware, the high-level operations are +CEC protocol driven. The following high-level callbacks are available: + +struct cec_adap_ops { + /* Low-level callbacks */ + ... + + /* High-level CEC message callback */ + int (*received)(struct cec_adapter *adap, struct cec_msg *msg); +}; + +The received() callback allows the driver to optionally handle a newly +received CEC message + + int (*received)(struct cec_adapter *adap, struct cec_msg *msg); + +If the driver wants to process a CEC message, then it can implement this +callback. If it doesn't want to handle this message, then it should return +-ENOMSG, otherwise the CEC framework assumes it processed this message and +it will not no anything with it. + + +CEC framework functions +----------------------- + +CEC Adapter drivers can call the following CEC framework functions: + +int cec_transmit_msg(struct cec_adapter *adap, struct cec_msg *msg, + bool block); + +Transmit a CEC message. If block is true, then wait until the message has been +transmitted, otherwise just queue it and return. + +void cec_s_phys_addr(struct cec_adapter *adap, u16 phys_addr, bool block); + +Change the physical address. This function will set adap->phys_addr and +send an event if it has changed. If cec_s_log_addrs() has been called and +the physical address has become valid, then the CEC framework will start +claiming the logical addresses. If block is true, then this function won't +return until this process has finished. + +When the physical address is set to a valid value the CEC adapter will +be enabled (see the adap_enable op). When it is set to CEC_PHYS_ADDR_INVALID, +then the CEC adapter will be disabled. If you change a valid physical address +to another valid physical address, then this function will first set the +address to CEC_PHYS_ADDR_INVALID before enabling the new physical address. + +int cec_s_log_addrs(struct cec_adapter *adap, + struct cec_log_addrs *log_addrs, bool block); + +Claim the CEC logical addresses. Should never be called if CEC_CAP_LOG_ADDRS +is set. If block is true, then wait until the logical addresses have been +claimed, otherwise just queue it and return. To unconfigure all logical +addresses call this function with log_addrs set to NULL or with +log_addrs->num_log_addrs set to 0. The block argument is ignored when +unconfiguring. This function will just return if the physical address is +invalid. Once the physical address becomes valid, then the framework will +attempt to claim these logical addresses. -- cgit v0.10.2 From d69bb093a79e77955e05616c5158291c9a306e95 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 24 Jun 2016 08:30:15 -0300 Subject: usbvision: remove some unused vars Gcc 6.1 warns about some unused vars.

Date: Sat, 4 Jun 2016 20:47:15 -0300 Subject: [media] tw686x: Introduce an interface to support multiple DMA modes Let's set the corner stone to support all the DMA modes available on this device. For stability reasons, the driver is currently setting DMA frame mode, and using single DMA buffers to get the P and B buffers. Each frame is then memcpy'ed into the user buffer. However, other platforms might be interested in avoiding this memcpy, or in taking advantage of the chip's DMA scatter-gather capabilities. To achieve this, this commit introduces a "dma_mode" module parameter, and a tw686x_dma_ops struct. This will allow to define functions to alloc/free DMA buffers, and to return the frames to userspace. The memcpy-based method described above is named as dma_mode="memcpy". Current alloc/free functions are renamed as tw686x_memcpy_xxx, and are now used through a memcpy_dma_ops.

This switches the operating mode to slave. The s_stream function sets the correct mode. But this caused problems on a board where the camera chip is operated as master. The camera started after a random amount of time streaming an image, I observed between 10 and 300 seconds. The STRFM_OUT and STLN_OUT pins are not connected on this board which may cause some issues in slave mode. I could not find any documentation about this. Keeping the chip in master mode after the reset helped to fix this issue for me.

50f7d5a65e5a31e92a9d46663770cd9509f939a2 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 17 Jun 2016 09:20:52 -0300 Subject: [media] cec-funcs.h: static inlines to pack/unpack CEC messages This public header contains static inlines to pack and unpack CEC messages. It is for use in both the kernel and in userspace. Since the CEC framework will initially be in staging this header is not yet in include/uapi. Once the framework is moved out of staging this header should be moved to uapi at the same time.

Note that the CEC framework is added to staging/media and that the cec.h and cec-funcs.h headers are not exported yet. While the kABI is mature, I would prefer to allow the uABI some more time before it is mainlined in case it needs more tweaks. This adds the cec-core.c, media/cec.h and cec-priv.h sources.

Note that the CEC framework is added to staging/media and that the cec.h and cec-funcs.h headers are not exported yet. While the kABI is mature, I would prefer to allow the uABI some more time before it is mainlined in case it needs more tweaks. This adds the cec-adap.c source that deals with the low-level CEC messaging and logical address handling.

Note that the CEC framework is added to staging/media and that the cec.h and cec-funcs.h headers are not exported yet. While the kABI is mature, I would prefer to allow the uABI some more time before it is mainlined in case it needs more tweaks. This adds the cec-api.c source that deals with the public CEC API and the Kconfig/Makefile plumbing. The MAINTAINERS file is also updated.

+ Introduction + + Note: this documents the proposed CEC API. This API is not yet finalized and + is currently only available as a staging kernel module. + + HDMI connectors provide a single pin for use by the Consumer Electronics + Control protocol. This protocol allows different devices connected by an HDMI cable + to communicate. The protocol for CEC version 1.4 is defined in supplements 1 (CEC) + and 2 (HEAC or HDMI Ethernet and Audio Return Channel) of the HDMI 1.4a + () specification and the extensions added to CEC version 2.0 + are defined in chapter 11 of the HDMI 2.0 () specification. + + + The bitrate is very slow (effectively no more than 36 bytes per second) and + is based on the ancient AV.link protocol used in old SCART connectors. The protocol + closely resembles a crazy Rube Goldberg contraption and is an unholy mix of low and + high level messages. Some messages, especially those part of the HEAC protocol layered + on top of CEC, need to be handled by the kernel, others can be handled either by the + kernel or by userspace. + + In addition, CEC can be implemented in HDMI receivers, transmitters and in USB + devices that have an HDMI input and an HDMI output and that control just the CEC pin. + + Drivers that support CEC will create a CEC device node (/dev/cecX) + to give userspace access to the CEC adapter. The &CEC-ADAP-G-CAPS; ioctl will tell userspace + what it is allowed to do. +

When doing so it assumes both that the pipeline has been correctly configured with an output, and that inputs are are stored in the pipe inputs array at positions 0 to num_inputs-1. Both the assumptions are incorrect. The pipeline might need to be reset after a failed attempts to configure it, without any output specified. Furthermore, inputs are stored in a positiong equal to their RPF index, possibly creating holes in the inputs array if the RPFs are not used in sequence. Fix both issues by looping over the whole inputs array and skipping unused entries, and ignoring the output when not set.

To enable runtime modification of controls we need to call the configure operations for every frame. Doing so is currently not safe, as most parameters shouldn't be modified during streaming. Furthermore the configure operation can sleep, preventing it from being called from the frame completion interrupt handler for the next frame. Fix this by adding an argument to the configure operation to tell entities whether to perform a full configuration (as done now) or a partial runtime configuration. In the latter case the operation will only configure the subset of parameters related to runtime-configurable controls, and won't be allowed to sleep when doing so. Because partial reconfiguration can depend on parameters computed when performing a full configuration, the core guarantees that the configure operation will always be called with full and partial modes in that order at stream start. Entities thus don't have to duplicate configuration steps in the full and partial code paths. This change affects the VSP driver core only, all entities return immediately from the configure operation when called for a partial runtime configuration. Entities will be modified one by one in further commits.

It is able to handle video decoding/encoding of in a range of formats. The driver provides with VPU firmware download, memory management and the communication interface between CPU and VPU. For VPU initialization, it will create virtual memory for CPU access and IOMMU address for vcodec hw device access. When a decode/encode instance opens a device node, vpu driver will download vpu firmware to the device. A decode/encode instant will decode/encode a frame using VPU interface to interrupt vpu to handle decoding/encoding jobs.

Drop the old allocate context code since that is no longer used. Note that the memops functions now get a struct device pointer instead of the struct device ** that was there initially (actually a void pointer to a struct containing only a struct device pointer).

However, this pointer points to memory from the keymap module itself. Since these keymap modules are not refcounted, that means anyone can call rmmod to unload that module. Which is not a big deal because the contents of the map is all copied to rc_map, except for the keymap name. So after a keymap module is unloaded the name pointer has become stale. Unloading the rc-core module will now cause a kernel oops in rc_dev_uevent(). The solution is to kstrdup the name so there are no more references to the keymap module remaining.

It has a single work item(&sd->work) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. Work item has been flushed in sd_stop0() to ensure that there are no pending tasks while disconnecting the driver.

charset=UTF-8 Content-Transfer-Encoding: 8bit Fix RC5 decoding with Fintek CIR chipset Commit e87b540be2dd02552fb9244d50ae8b4e4619a34b tightened up the RC5 decoding by adding a check for trailing silence to ensure a valid RC5 command had been received. Unfortunately the trailer length checked was 10 units and the Fintek CIR device does not want to provide details of a space longer than 6350us. This meant that RC5 remotes working on a Fintek setup on 3.16 failed on 3.17 and later. Fix this by shortening the trailer check to 6 units (allowing for a previous space in the received remote command).

The vulnerability is triggered when more than 64 usb devices register with v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV.A badusb device can emulate 64 of these devices then through continual emulated connect/disconnect of the 65th device, cause the kernel to run out of RAM and crash the kernel. The vulnerability exists in kernel versions from 3.17 to current 4.7. The memory leak is caused by the probe function of the airspy driver mishandeling errors and not freeing the corresponding control structures when an error occours registering the device to v4l2 core.
