MAINTAINERS & files: Canonize the e-mails I use at files

2018-05-04T10:21:06Z

From now on, I'll start using my @kernel.org as my development e-mail. As such, let's remove the entries that point to the old mchehab@s-opensource.com at MAINTAINERS file. 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. For bug reports, we can simply point to just kernel.org, as this will reach my mchehab+samsung inbox anyway.

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 ...

media: v4l2-core: fix size of devnode_nums[] bitarray

2018-04-05T10:41:30Z

The size of devnode_nums[] bit array is too short to store information for VFL_TYPE_TOUCH. That causes it to override other memory regions. Thankfully, on recent reports, it is overriding video_device[] array, trigging a WARN_ON(). Yet, it just warns about the problem, but let the code excecuting, with generates an OOPS: [ 43.177394] WARNING: CPU: 1 PID: 711 at drivers/media/v4l2-core/v4l2-dev.c:945 __video_register_device+0xc99/0x1090 [videodev] [ 43.177396] Modules linked in: hid_sensor_custom hid_sensor_als hid_sensor_incl_3d hid_sensor_rotation hid_sensor_magn_3d hid_sensor_accel_3d hid_sensor_gyro_3d hid_sensor_trigger industrialio_triggered_buffer kfifo_buf joydev hid_sensor_iio_common hid_rmi(+) rmi_core industrialio videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_common videodev hid_multitouch media hid_sensor_hub binfmt_misc nls_iso8859_1 snd_hda_codec_hdmi arc4 snd_soc_skl snd_soc_skl_ipc snd_hda_ext_core snd_soc_sst_dsp snd_soc_sst_ipc snd_hda_codec_realtek snd_soc_acpi snd_hda_codec_generic snd_soc_core snd_compress ac97_bus snd_pcm_dmaengine snd_hda_intel snd_hda_codec intel_rapl snd_hda_core x86_pkg_temp_thermal snd_hwdep intel_powerclamp coretemp snd_pcm kvm_intel snd_seq_midi snd_seq_midi_event snd_rawmidi crct10dif_pclmul [ 43.177426] crc32_pclmul ghash_clmulni_intel iwlmvm pcbc mac80211 snd_seq aesni_intel iwlwifi aes_x86_64 snd_seq_device crypto_simd glue_helper cryptd snd_timer intel_cstate intel_rapl_perf input_leds serio_raw intel_wmi_thunderbolt snd wmi_bmof cfg80211 soundcore ideapad_laptop sparse_keymap idma64 virt_dma tpm_crb acpi_pad int3400_thermal acpi_thermal_rel intel_pch_thermal processor_thermal_device mac_hid int340x_thermal_zone mei_me intel_soc_dts_iosf mei intel_lpss_pci shpchp intel_lpss sch_fq_codel vfio_pci nfsd vfio_virqfd parport_pc ppdev auth_rpcgss nfs_acl lockd grace lp parport sunrpc ip_tables x_tables autofs4 hid_logitech_hidpp hid_logitech_dj hid_generic usbhid kvmgt vfio_mdev mdev vfio_iommu_type1 vfio kvm irqbypass i915 i2c_algo_bit drm_kms_helper syscopyarea sdhci_pci sysfillrect [ 43.177466] sysimgblt cqhci fb_sys_fops sdhci drm i2c_hid wmi hid video pinctrl_sunrisepoint pinctrl_intel [ 43.177474] CPU: 1 PID: 711 Comm: systemd-udevd Not tainted 4.16.0 #1 [ 43.177475] Hardware name: LENOVO 80UE/VIUU4, BIOS 2UCN10T 10/14/2016 [ 43.177481] RIP: 0010:__video_register_device+0xc99/0x1090 [videodev] [ 43.177482] RSP: 0000:ffffa5c5c231b420 EFLAGS: 00010202 [ 43.177484] RAX: 0000000000000000 RBX: 0000000000000005 RCX: 0000000000000000 [ 43.177485] RDX: ffffffffc0c44cc0 RSI: ffffffffffffffff RDI: ffffffffc0c44cc0 [ 43.177486] RBP: ffffa5c5c231b478 R08: ffffffffc0c96900 R09: ffff8eda1a51f018 [ 43.177487] R10: 0000000000000600 R11: 00000000000003b6 R12: 0000000000000000 [ 43.177488] R13: 0000000000000005 R14: ffffffffc0c96900 R15: ffff8eda1d6d91c0 [ 43.177489] FS: 00007fd2d8ef2480(0000) GS:ffff8eda33480000(0000) knlGS:0000000000000000 [ 43.177490] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 43.177491] CR2: 00007ffe0a6ad01c CR3: 0000000456ae2004 CR4: 00000000003606e0 [ 43.177492] Call Trace: [ 43.177498] ?

media: v4l: Bring back array_size parameter to v4l2_find_nearest_size

2018-04-04T10:12:53Z

An older version of the driver patches were merged accidentally which resulted in missing the array_size parameter that tells the length of the array that contains the different supported sizes. Bring it back to v4l2_find_nearest size and make the corresponding change for the drivers using it as well. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: cec: improve CEC pin event handling

2018-03-22T12:16:52Z

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. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec: add core error injection support

2018-03-22T11:59:31Z

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.

media: v4l2-common: fix a compilation breakage

Clearly, changeset 95ce9c28601a ("media: v4l: common: Add a function to obtain best size from a list") was never tested, as it broke compilation with: drivers/media/platform/vivid/vivid-vid-cap.c: In function ‘vivid_try_fmt_vid_cap’: drivers/media/platform/vivid/vivid-vid-cap.c:565:34: error: macro "v4l2_find_nearest_size" requer 6 argumentos, mas apenas 5 foram fornecidos mp->width, mp->height); ^ drivers/media/platform/vivid/vivid-vid-cap.c:564:4: error: ‘v4l2_find_nearest_size’ undeclared (first use in this function); did you mean ‘__v4l2_find_nearest_size’? v4l2_find_nearest_size(webcam_sizes, width, height, ^~~~~~~~~~~~~~~~~~~~~~ __v4l2_find_nearest_size drivers/media/platform/vivid/vivid-vid-cap.c:564:4: note: each undeclared identifier is reported only once for each function it appears in drivers/media/i2c/ov5670.c: In function ‘ov5670_set_pad_format’: drivers/media/i2c/ov5670.c:2233:48: error: macro "v4l2_find_nearest_size" requer 6 argumentos, mas apenas 5 foram fornecidos fmt->format.width, fmt->format.height); ^ drivers/media/i2c/ov5670.c:2232:9: error: ‘v4l2_find_nearest_size’ undeclared (first use in this function); did you mean ‘__v4l2_find_nearest_size’? mode = v4l2_find_nearest_size(supported_modes, width, height, ^~~~~~~~~~~~~~~~~~~~~~ __v4l2_find_nearest_size drivers/media/i2c/ov13858.c: In function ‘ov13858_set_pad_format’: drivers/media/i2c/ov13858.c:1379:48: error: macro "v4l2_find_nearest_size" requer 6 argumentos, mas apenas 5 foram fornecidos fmt->format.width, fmt->format.height); ^ drivers/media/i2c/ov13858.c:1378:9: error: ‘v4l2_find_nearest_size’ undeclared (first use in this function); did you mean ‘__v4l2_find_nearest_size’? mode = v4l2_find_nearest_size(supported_modes, width, height, ^~~~~~~~~~~~~~~~~~~~~~ __v4l2_find_nearest_size drivers/media/i2c/ov13858.c:1378:9: note: each undeclared identifier is reported only once for each function it appears in Basically, v4l2_find_nearest_size() callers pass 5 arguments, while its definition require 6 args.
