[media] tuner-core/v4l2-subdev: document that the type field has to be filled in

2011-07-07T18:04:23Z

The tuner ops g_frequency, g_tuner and s_tuner require that the tuner type field is filled in. Document this. The tuner-core doc is based on a patch from Mauro Carvalho Chehab . Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] lirc_dev: store cdev in irctl, up maxdevs

2011-06-11T12:03:20Z

Store the cdev pointer in struct irctl, allocated dynamically as needed, rather than having a static array. At the same time, recycle some of the saved memory to nudge the maximum number of lirc devices supported up a ways -- its not that uncommon these days, now that we have the rc-core lirc bridge driver, to see a system with at least 4 raw IR receivers. (consider a mythtv backend with several video capture devices and the possible need for IR transmit hardware). Signed-off-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab

[media] v4l: Fix media_entity_to_video_device macro argument name

2011-06-01T12:42:03Z

The name 'entity' is used twice in the macro body, once as the macro argument, and once as a structure field name. This breaks compilation if the macro is called with its argument not named 'entity'. Fix this by renaming the macro argument '__e'. This should avoid namespace clashes. Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] rc: add locking to fix register/show race

2011-05-20T19:21:22Z

When device_add is called in rc_register_device, the rc sysfs nodes show up, and there's a window in which ir-keytable can be launched via udev and trigger a show_protocols call, which runs without various rc_dev fields filled in yet. Add some locking around registration and store/show_protocols to prevent that from happening. The problem manifests thusly: [64692.957872] BUG: unable to handle kernel NULL pointer dereference at 0000000000000090 [64692.957878] IP: [] show_protocols+0x47/0xf1 [rc_core] [64692.957890] PGD 19cfc7067 PUD 19cfc6067 PMD 0 [64692.957894] Oops: 0000 [#1] SMP [64692.957897] last sysfs file: /sys/devices/pci0000:00/0000:00:03.1/usb3/3-1/3-1:1.0/rc/rc2/protocols [64692.957902] CPU 3 [64692.957903] Modules linked in: redrat3(+) ir_lirc_codec lirc_dev ir_sony_decoder ir_jvc_decoder ir_rc6_decoder ir_rc5_decoder rc_hauppauge ir_nec _decoder rc_core ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 ip6table_filter ip6_tables snd_emu10k1_synth snd_emux_synth snd_seq_virmidi snd_seq_mi di_event snd_seq_midi_emul snd_emu10k1 snd_rawmidi snd_ac97_codec ac97_bus snd_seq snd_pcm snd_seq_device snd_timer snd_page_alloc snd_util_mem pcsp kr tg3 snd_hwdep emu10k1_gp snd amd64_edac_mod gameport edac_core soundcore edac_mce_amd k8temp shpchp i2c_piix4 lm63 e100 mii uinput ipv6 raid0 rai d1 ata_generic firewire_ohci pata_acpi firewire_core crc_itu_t sata_svw pata_serverworks floppy radeon ttm drm_kms_helper drm i2c_algo_bit i2c_core [last unloaded: redrat3] [64692.957949] [64692.957952] Pid: 12265, comm: ir-keytable Tainted: G M W 2.6.39-rc6+ #2 empty empty/TYAN Thunder K8HM S3892 [64692.957957] RIP: 0010:[] [] show_protocols+0x47/0xf1 [rc_core] [64692.957962] RSP: 0018:ffff880194509e38 EFLAGS: 00010202 [64692.957964] RAX: 0000000000000000 RBX: ffffffffa036d1e0 RCX: ffffffffa036a47a [64692.957966] RDX: ffff88019a84d000 RSI: ffffffffa036d1e0 RDI: ffff88019cf2f3f0 [64692.957969] RBP: ffff880194509e68 R08: 0000000000000002 R09: 0000000000000000 [64692.957971] R10: 0000000000000002 R11: 0000000000001617 R12: ffff88019a84d000 [64692.957973] R13: 0000000000001000 R14: ffff8801944d2e38 R15: ffff88019ce5f190 [64692.957976] FS: 00007f0a30c9a720(0000) GS:ffff88019fc00000(0000) knlGS:0000000000000000 [64692.957979] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [64692.957981] CR2: 0000000000000090 CR3: 000000019a8e0000 CR4: 00000000000006e0 [64692.957983] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [64692.957986] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [64692.957989] Process ir-keytable (pid: 12265, threadinfo ffff880194508000, task ffff88019a9fc720) [64692.957991] Stack: [64692.957992] 0000000000000002 ffffffffa036d1e0 ffff880194509f58 0000000000001000 [64692.957997] ffff8801944d2e38 ffff88019ce5f190 ffff880194509e98 ffffffff8131484b [64692.958001] ffffffff8118e923 ffffffff810e9b2f ffff880194509e98 ffff8801944d2e18 [64692.958005] Call Trace: [64692.958014] [] dev_attr_show+0x27/0x4e [64692.958014] [] ? sysfs_read_file+0x94/0x172 [64692.958014] [] ? __get_free_pages+0x16/0x52 [64692.958014] [] sysfs_read_file+0xbd/0x172 [64692.958014] [] vfs_read+0xac/0xf3 [64692.958014] [] ? fget_light+0x3a/0xa1 [64692.958014] [] sys_read+0x4d/0x74 [64692.958014] [] system_call_fastpath+0x16/0x1b Its a bit difficult to reproduce, but I'm fairly confident this has fixed the problem.

[media] V4L: soc-camera: add a new packing for YUV 4:2:0 type formats

2011-05-20T15:05:08Z

12-bit formats, similar to YUV 4:2:0 occupy 3 bytes for each two pixels and cannot be described by any of the existing SOC_MBUS_PACKING_* macros. This patch adds a new one SOC_MBUS_PACKING_1_5X8 to describe such formats and extends soc_mbus_samples_per_pixel() to support it.
