2020-02-24media: v4l2-device.h: Explicitly compare grp{id,mask} to zero in v4l2_device ↵Nathan Chancellor
macros [ Upstream commit afb34781620274236bd9fc9246e22f6963ef5262 ] When building with Clang + -Wtautological-constant-compare, several of the ivtv and cx18 drivers warn along the lines of: drivers/media/pci/cx18/cx18-driver.c:1005:21: warning: converting the result of '<<' to a boolean always evaluates to true [-Wtautological-constant-compare] cx18_call_hw(cx, CX18_HW_GPIO_RESET_CTRL, ^ drivers/media/pci/cx18/cx18-cards.h:18:37: note: expanded from macro 'CX18_HW_GPIO_RESET_CTRL' #define CX18_HW_GPIO_RESET_CTRL (1 << 6) ^ 1 warning generated. This warning happens because the shift operation is implicitly converted to a boolean in v4l2_device_mask_call_all before being negated. This can be solved by just comparing the mask result to 0 explicitly so that there is no boolean conversion. The ultimate goal is to enable -Wtautological-compare globally because there are several subwarnings that would be helpful to have. For visual consistency and avoidance of these warnings in the future, all of the implicitly boolean conversions in the v4l2_device macros are converted to explicit ones as well.

commit f51e50db4c20d46930b33be3f208851265694f3e upstream. boundary->width and boundary->height are sizes relative to boundary->left and boundary->top coordinates, but they were not being taken into consideration to adjust r->left and r->top, leading to the following error: Consider the follow as initial values for boundary and r: struct v4l2_rect boundary = { .left = 100, .top = 100, .width = 800, .height = 600, } struct v4l2_rect r = { .left = 0, .top = 0, .width = 1920, .height = 960, } calling v4l2_rect_map_inside(&r, &boundary) was modifying r to: r = { .left = 0, .top = 0, .width = 800, .height = 600, } Which is wrongly outside the boundary rectangle, because: v4l2_rect_set_max_size(r, boundary); // r->width = 800, r->height = 600 ... if (r->left + r->width > boundary->width) // true r->left = boundary->width - r->width; // r->left = 800 - 800 if (r->top + r->height > boundary->height) // true r->top = boundary->height - r->height; // r->height = 600 - 600 Fix this by considering top/left coordinates from boundary.

2019-09-16media: cec/v4l2: move V4L2 specific CEC functions to V4L2Hans Verkuil
[ Upstream commit 9cfd2753f8f3923f89cbb15f940f3aa0e7202d3e ] Several CEC functions are actually specific for use with receivers, i.e. they should be part of the V4L2 subsystem, not CEC. These functions deal with validating and modifying EDIDs for (HDMI) receivers, and they do not actually have anything to do with the CEC subsystem and whether or not CEC is enabled. The problem was that if the CEC_CORE config option was not set, then these functions would become stubs, but that's not right: they should always be valid. So replace the cec_ prefix by v4l2_ and move them to v4l2-dv-timings.c. Update all drivers that call these accordingly.

2019-05-31media: vb2: add waiting_in_dqbuf flagHans Verkuil
commit d65842f7126aa1a87fb44b7c9980c12630ed4f33 upstream. Calling VIDIOC_DQBUF can release the core serialization lock pointed to by vb2_queue->lock if it has to wait for a new buffer to arrive. However, if userspace dup()ped the video device filehandle, then it is possible to read or call DQBUF from two filehandles at the same time. It is also possible to call REQBUFS from one filehandle while the other is waiting for a buffer. This will remove all the buffers and reallocate new ones. Removing all the buffers isn't the problem here (that's already handled correctly by DQBUF), but the reallocating part is: DQBUF isn't aware that the buffers have changed. This is fixed by setting a flag whenever the lock is released while waiting for a buffer to arrive. And checking the flag where needed so we can return -EBUSY.

2019-01-09media: cec: keep track of outstanding transmitsHans Verkuil
commit 32804fcb612bf867034a093f459415e485cf044b upstream. I noticed that repeatedly running 'cec-ctl --playback' would occasionally select 'Playback Device 2' instead of 'Playback Device 1', even though there were no other Playback devices in the HDMI topology. This happened both with 'real' hardware and with the vivid CEC emulation, suggesting that this was an issue in the core code that claims a logical address. What 'cec-ctl --playback' does is to first clear all existing logical addresses, and immediately after that configure the new desired device type. The core code will poll the logical addresses trying to find a free address. When found it will issue a few standard messages as per the CEC spec and return. Those messages are queued up and will be transmitted asynchronously. What happens is that if you run two 'cec-ctl --playback' commands in quick succession, there is still a message of the first cec-ctl command being transmitted when you reconfigure the adapter again in the second cec-ctl command. When the logical addresses are cleared, then all information about outstanding transmits inside the CEC core is also cleared, and the core is no longer aware that there is still a transmit in flight. When the hardware finishes the transmit it calls transmit_done and the CEC core thinks it is actually in response of a POLL messages that is trying to find a free logical address. The result of all this is that the core thinks that the logical address for Playback Device 1 is in use, when it is really an earlier transmit that ended. The main transmit thread looks at adap->transmitting to check if a transmit is in progress, but that is set to NULL when the adapter is unconfigured. adap->transmitting represents the view of userspace, not that of the hardware. So when unconfiguring the adapter the message is marked aborted from the point of view of userspace, but seen from the PoV of the hardware it is still ongoing. So introduce a new bool transmit_in_progress that represents the hardware state and use that instead of adap->transmitting. Now the CEC core waits until the hardware finishes the transmit before starting a new transmit.

commit 7d867a1b765e2b70815fec4964d7822a976ed349 upstream. The calculation of the Signal Free Time in the framework was not correct. If a message was received, then the next transmit should be considered a New Initiator and use a shorter SFT value. This was not done with the result that if both sides where continually sending messages, they both could use the same SFT value and one side could deny the other side access to the bus. Note that this fix does not take the corner case into account where a receive is in progress when you call adap_transmit.

commit b915bf575d5b7774d0f22d57d6c143e07dcaade2 upstream. This function is needed by both V4L2 and CEC, so move this to cec.h as a static inline since there are no obvious shared modules between the two subsystems. This patch, together with the following ones, fixes a dependency bug: if CEC_CORE is disabled, then building adv7604 (and other HDMI receivers) will fail because an essential function is now stubbed out.

2018-10-03media: v4l: event: Prevent freeing event subscriptions while accessedSakari Ailus
The event subscriptions are added to the subscribed event list while holding a spinlock, but that lock is subsequently released while still accessing the subscription object. This makes it possible to unsubscribe the event --- and freeing the subscription object's memory --- while the subscription object is simultaneously accessed. Prevent this by adding a mutex to serialise the event subscription and unsubscription. This also gives a guarantee to the callback ops that the add op has returned before the del op is called. This change also results in making the elems field less special: subscriptions are only added to the event list once they are fully initialised.

Example for such a crash: general protection fault: 0000 [#1] SMP CPU: 1 PID: 301 Comm: vdr Not tainted 4.8.1-nuc+ #102 [142B blob data] task: ffff8802301f2040 task.stack: ffff880233728000 RIP: 0010:[<ffffffff816c296b>] [<ffffffff816c296b>] dvb_frontend_release+0xcb/0x120 RSP: 0018:ffff88023372bdd8 EFLAGS: 00010202 RAX: 001fd55c000000da RBX: ffff880236bad810 RCX: 0000000000000000 RDX: ffff880235bd81f0 RSI: 0000000000000246 RDI: ffff880235bd81e8 RBP: ffff88023372be00 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: ffff88022f009910 R12: 0000000000000000 R13: ffff880235a21a80 R14: ffff880235bd8000 R15: ffff880235bb8a78 FS: 0000000000000000(0000) GS:ffff88023fd00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f96edd69818 CR3: 0000000002406000 CR4: 00000000001006e0 Stack: ffff88022f009900 0000000000000008 ffff880235bb8a78 ffff8802344fbb20 ffff880236437b40 ffff88023372be48 ffffffff8117a81e ffff880235bb8a78 ffff88022f009910 ffff8802335a7400 ffff8802301f2040 ffff88022f009900 Call Trace: [<ffffffff8117a81e>] __fput+0xde/0x1d0 [<ffffffff8117a949>] ____fput+0x9/0x10 [<ffffffff810a9fce>] task_work_run+0x7e/0xa0 [<ffffffff81094bab>] do_exit+0x27b/0xa50 [<ffffffff810407e3>] ? __do_page_fault+0x1c3/0x430 [<ffffffff81095402>] do_group_exit+0x42/0xb0 [<ffffffff8109547f>] SyS_exit_group+0xf/0x10 [<ffffffff8108bedb>] entry_SYSCALL_64_fastpath+0x13/0x8f Code: 31 c9 49 8d be e8 01 00 00 ba 01 00 00 00 be 03 00 00 00 e8 68 2d a0 ff 48 8b 83 10 03 00 00 48 8b 80 88 00 00 00 48 85 c0 74 12 <48> 8b 80 88 02 00 00 48 85 c0 74 06 49 8b 7d RIP [<ffffffff816c296b>] dvb_frontend_release+0xcb/0x120 [mchehab+samsung@kernel.org: fix a Coding Style issue] Signed-off-by: Max Kellermann <max.kellermann@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

The mdev field is only present if CONFIG_MEDIA_CONTROLLER is set. But since we will need to pass the media_device to vb2 and the control framework it is very convenient to just make this field available all the time. If CONFIG_MEDIA_CONTROLLER is not set, then it will just be NULL.

For the files written with a copyright with mchehab@s-opensource, let's keep Samsung on their names, using mchehab+samsung@kernel.org, in order to keep pointing to my employer, with sponsors the work. For the files written before I join Samsung (on July, 4 2013), let's just use mchehab@kernel.org.

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media fixes from Mauro Carvalho Chehab: "A series of media updates/fixes for 4.17. There are two important core fix patches in this series: - A regression fix on Kernel 4.16 with causes it to not work with some input devices that depend on media core - A fix at compat32 bits with causes it to OOPS on overlay, and affects the Kernels where the CVE-2017-13166 was backported The remaining ones are other random fixes at the documentation and on drivers. The biggest part of this series is a set of 18 patches for the Intel atomisp driver. Currently, it produces hundreds of warnings/errors on sparse/smatch, causing me to sometimes ignore new warnings on other drivers that are not so broken. This driver is on really poor state, even for staging standards: it has several layers of abstraction on it, and it supports two different hardware. Selecting between them require to add a define (there isn't even a Kconfig option for such purpose). Just on this smatch cleanup, I could easily get rid of 8 "do-nothing" files. So, I'm seriously considering its removal from upstream, if I don't see any real work on addressing the problems there along this year" * tag 'media/v4.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (48 commits) media: v4l2-core: fix size of devnode_nums[] bitarray media: v4l2-compat-ioctl32: don't oops on overlay media: i2c: adv748x: afe: fix sparse warning media: extended-controls.rst: transmitter -> receiver media: staging: atomisp: stop duplicating input format types media: staging: atomisp: get rid of an unused var media: staging: atomisp: stop mixing enum types media: staging: atomisp: get rid of some static warnings media: staging: atomisp: use %p to print pointers media: staging: atomisp: remove an useless check media: staging: atomisp: avoid a warning if 32 bits build media: staging: atomisp: don't access a NULL var media: staging: atomisp: Get rid of *default.host.[ch] media: staging: atomisp: get rid of an unused function media: staging: atomisp: remove unused set_pd_base() media: staging: atomisp: fix endianess issues media: staging: atomisp: add a missing include media: staging: atomisp: get rid of stupid statements media: staging: atomisp: declare static vars as such media: staging: atomisp: ia_css_output.host: don't use var before check ...

2018-03-22media: cec: improve CEC pin event handlingHans Verkuil
It turns out that the struct cec_fh event buffer size of 64 events (64 for CEC_EVENT_PIN_CEC_LOW and 64 for _HIGH) is too small. It's about 160 ms worth of events and if the Raspberry Pi is busy, then it might take too long for the application to be scheduled so that it can drain the pending events. Increase these buffers to 800 events which is at least 2 seconds worth of events. There is also a FIFO in between the interrupt and the cec-pin thread. The thread passes the events on to the CEC core. It is important that should this FIFO fill up the cec core will be informed that events have been lost so this can be communicated to the user by setting CEC_EVENT_FL_DROPPED_EVENTS. It is very hard to debug CEC problems if events were lost without informing the user of that fact. If events were dropped due to the FIFO filling up, then the debugfs status file will let you know how many events were dropped.

Add two new ops (error_inj_show and error_inj_parse_line) to support error injection functionality for CEC adapters. If both are present, then the core will add a new error-inj debugfs file that can be used to see the current error injection commands and to set error injection commands.

2018-03-21media: i2c: mt9t112: Remove soc_camera dependenciesJacopo Mondi
Remove soc_camera framework dependencies from mt9t112 sensor driver. - Handle clk, gpios and power routines - Register async subdev - Remove deprecated g/s_mbus_config operations - Remove driver flags - Change driver interface and add kernel doc - Adjust build system - Fix code style issues reported by checkpatch in strict mode This commit does not remove the original soc_camera based driver as long as other platforms depends on soc_camera framework. As I don't have access to a working camera module, this change has only been compile tested.
