From 1b9e94dc69959e963fe57ede46259f792641af4d Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 9 Sep 2012 09:23:31 -0300 Subject: [media] bttv: add VIDIOC_DBG_G_CHIP_IDENT VIDIOC_DBG_G_CHIP_IDENT is a prerequisite for the G/S_REGISTER ioctls. In addition, add support to call G/S_REGISTER for supporting i2c devices.

Also fixes a mute/automute problem where closing the file handle would force mute on. That's not what you want since that would make the mute state out of sync with the mute control. Instead check against the user count.

What you really want is to know if gamma_width fits inside data_size and for that you need to translate each enum into a maximum bit number so you can safely compare the two. So I put in two static inline translation functions instead, keeping the rest of the code the same (except for fixing the 'gama' typo).

Make it possible to specify additional GFP flags for those buffers by adding a gfp_flags field to vb2_queue. Note that this field will be replaced in the future with a different mechanism, but that is still work in progress and we need this feature now so we won't be able to convert drivers with such requirements to vb2.

First of all, it is pretty bogus to change the protocol type of the keymap just because the hardware has been asked to decode a different protocol. Second, dev->rc_map.rc_type is an enum (i.e. a single protocol) as pointed out by James Hogan . Fix both issues by introducing a separate enabled_protocols member to struct rc_dev.

I could have chosen to add const instead, but this is 1) easier to handle in drivers and 2) consistent with the s_std subdev operation.

This happened because all struct v4l2_ctrl_handler.lock mutexes were created as members of the same lock class in v4l2_ctrl_handler_init(), and v4l2_ctrl_add_handler() takes the hdl->lock on two different v4l2_ctrl_handler instances. This change breaks the large lockdep lock class for struct v4l2_ctrl_handler.lock and breaks it into v4l2_ctrl_handler instantiation specific lock classes with meaningful class names. This will validly eliminate lockdep alarms for v4l2_ctrl_handler locking validation, as long as the relationships between drivers adding v4l2 controls to their own handler from other v4l2 drivers' control handlers remains straightforward. struct v4l2_ctrl_handler.lock lock classes are created with names such that the output of cat /proc/lockdep indicates where in the v4l2 driver code v4l2_ctrl_handle_init() is being called on instantiations: ffffffffa045f490 FD: 10 BD: 8 +.+...: cx2341x:1534:(hdl)->lock ffffffffa0497d20 FD: 12 BD: 2 +.+.+.: saa7115:1581:(hdl)->lock ffffffffa04ac660 FD: 14 BD: 2 +.+.+.: msp3400_driver:756:(hdl)->lock ffffffffa0484b90 FD: 12 BD: 1 +.+.+.: ivtv_gpio:366:(&itv->hdl_gpio)->lock ffffffffa04eb530 FD: 11 BD: 2 +.+.+.: cx25840_core:1982:(&state->hdl)->lock ffffffffa04fbc80 FD: 11 BD: 3 +.+.+.: wm8775:246:(&state->hdl)->lock Some lock chains, that were previously causing the recursion alarms, are now visible in the output of cat /proc/lockdep_chains: irq_context: 0 [ffffffffa0497d20] saa7115:1581:(hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa04ac660] msp3400_driver:756:(hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa0484b90] ivtv_gpio:366:(&itv->hdl_gpio)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa04eb530] cx25840_core:1982:(&state->hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa04fbc80] wm8775:246:(&state->hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock Signed-off-by: Andy Walls [hans.verkuil@cisco.com: keep mutex_init in v4l2_ctrl_handler_init_class] Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/v4l2-core/v4l2-ctrls.c | 8 +++++--- include/media/v4l2-ctrls.h | 29 ++++++++++++++++++++++++++--- 2 files changed, 31 insertions(+), 6 deletions(-) (limited to 'include') diff --git a/drivers/media/v4l2-core/v4l2-ctrls.c b/drivers/media/v4l2-core/v4l2-ctrls.c index 6b28b5800500..b36d1ec13ee6 100644 --- a/drivers/media/v4l2-core/v4l2-ctrls.c +++ b/drivers/media/v4l2-core/v4l2-ctrls.c @@ -1362,11 +1362,13 @@ static inline int handler_set_err(struct v4l2_ctrl_handler *hdl, int err) } /* Initialize the handler */ -int v4l2_ctrl_handler_init(struct v4l2_ctrl_handler *hdl, - unsigned nr_of_controls_hint) +int v4l2_ctrl_handler_init_class(struct v4l2_ctrl_handler *hdl, + unsigned nr_of_controls_hint, + struct lock_class_key *key, const char *name) { hdl->lock = &hdl->_lock; mutex_init(hdl->lock); + lockdep_set_class_and_name(hdl->lock, key, name); INIT_LIST_HEAD(&hdl->ctrls); INIT_LIST_HEAD(&hdl->ctrl_refs); hdl->nr_of_buckets = 1 + nr_of_controls_hint / 8; @@ -1375,7 +1377,7 @@ int v4l2_ctrl_handler_init(struct v4l2_ctrl_handler *hdl, hdl->error = hdl->buckets ? 0 : -ENOMEM; return hdl->error; } -EXPORT_SYMBOL(v4l2_ctrl_handler_init); +EXPORT_SYMBOL(v4l2_ctrl_handler_init_class); /* Free all controls and control refs */ void v4l2_ctrl_handler_free(struct v4l2_ctrl_handler *hdl) diff --git a/include/media/v4l2-ctrls.h b/include/media/v4l2-ctrls.h index f00d42bc01a6..7343a27fe819 100644 --- a/include/media/v4l2-ctrls.h +++ b/include/media/v4l2-ctrls.h @@ -259,7 +259,7 @@ void v4l2_ctrl_fill(u32 id, const char **name, enum v4l2_ctrl_type *type, s32 *min, s32 *max, s32 *step, s32 *def, u32 *flags); -/** v4l2_ctrl_handler_init() - Initialize the control handler. +/** v4l2_ctrl_handler_init_class() - Initialize the control handler. * @hdl: The control handler. * @nr_of_controls_hint: A hint of how many controls this handler is * expected to refer to.

This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done by the name or index of subdevices or an index to a bridge chip. Most of this can all be done automatically, so most drivers just need to provide get/set register ops. In particular, it is now possible to get/set subdev registers without requiring assistance of the bridge driver.

This class is intended to all controls pertaining to FM receiver chips. Also, two controls belonging to said class are added as a part of this commit: V4L2_CID_TUNE_DEEMPHASIS and V4L2_CID_RDS_RECEPTION.

Since the I2C client's master clock is often provided by a video bus receiver (host interface) or other than I2C/SPI controller device, the drivers of those client devices are not accessing hardware in their driver's probe() callback. Instead, after enabling clock, the host driver calls back into a sub-device when it wants to activate them. This pattern is used by some in-tree drivers and this patch also uses it for DT case. This patch is intended as a first step for adding device tree support to the S5P/Exynos SoC camera drivers. The second one is adding support for asynchronous sub-devices registration and clock control from sub-device driver level. The bindings shall not change when asynchronous probing support is added.

Thus there is some limited colorspace conversion possible. This patch makes the color format variable be per FIMC-LITE input/output, rather than a global per device. This also fixes incorrect behavior where color format at the FIMC-LITE.N subdev's source pad is modified by VIDIOC_S_FMT ioctl on the related video node.

But with the new configuration options of tda8290 driver (no_i2c_gate and std_map), it's no longer sufficient. Change config to be void * instead, which allows passing tuner-dependent config struct to drivers. Also update saa7134 driver to reflect this change (no other driver uses this).
