From c8400c700723936d9333c977e51fa77062d26dd4 Mon Sep 17 00:00:00 2001 From: Thierry MERLE Date: Mon, 4 Dec 2006 08:31:04 -0300 Subject: [PATCH] V4L/DVB (4924): Fix some bugs on usbvision due to the merge into one module Found the bug that prevented the driver from loading : a module param conflict between usbvision-i2c and usbvision-core (debug parameter). - correct the module param "debug" conflics in usbvision-i2c.c and usbvision-core.c - add some debug printouts in usbvision-core.c VDIOC_QBUF/VIDIOC_DQBUF - usbvision-core.c : add vb->field = V4L2_FIELD_NONE in VIDIOC_DQBUF Signed-off-by: Thierry MERLE Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/usbvision/usbvision-core.c | 6 ++++-- drivers/media/video/usbvision/usbvision-i2c.c | 20 ++++++++------------ 2 files changed, 12 insertions(+), 14 deletions(-) diff --git a/drivers/media/video/usbvision/usbvision-core.c b/drivers/media/video/usbvision/usbvision-core.c index a23fcd1..da422e7 100644 --- a/drivers/media/video/usbvision/usbvision-core.c +++ b/drivers/media/video/usbvision/usbvision-core.c @@ -4240,6 +4240,7 @@ static int usbvision_v4l2_do_ioctl(struct inode *inode, struct file *file, /* set v4l2_format index */ frame->v4l2_format = usbvision->palette; + PDEBUG(DBG_IOCTL, "VIDIOC_QBUF frame=%d",vb->index); return usbvision_new_frame(usbvision, vb->index); } @@ -4269,8 +4270,8 @@ static int usbvision_v4l2_do_ioctl(struct inode *inode, struct file *file, if (vb->index == -1) return -EINVAL; - PDEBUG(DBG_IOCTL, "VIDIOC_DQBUF frame=%d, grabstate=%d", - vb->index, usbvision->frame[vb->index].grabstate); + PDEBUG(DBG_IOCTL, "VIDIOC_DQBUF frame=%d, grabstate=%d, curframeNum=%d", + vb->index, usbvision->frame[vb->index].grabstate,usbvision->curFrameNum); switch (usbvision->frame[vb->index].grabstate) { case FrameState_Unused: @@ -4295,6 +4296,7 @@ static int usbvision_v4l2_do_ioctl(struct inode *inode, struct file *file, errCode = (usbvision->frame[vb->index].grabstate == FrameState_Error) ? -EIO : 0; vb->memory = V4L2_MEMORY_MMAP; vb->flags = V4L2_BUF_FLAG_MAPPED | V4L2_BUF_FLAG_QUEUED | V4L2_BUF_FLAG_DONE; + vb->field = V4L2_FIELD_NONE; vb->sequence = usbvision->frame[vb->index].sequence; usbvision->frame[vb->index].grabstate = FrameState_Unused; break; diff --git a/drivers/media/video/usbvision/usbvision-i2c.c b/drivers/media/video/usbvision/usbvision-i2c.c index e050e55..466e11f 100644 --- a/drivers/media/video/usbvision/usbvision-i2c.c +++ b/drivers/media/video/usbvision/usbvision-i2c.c @@ -39,18 +39,14 @@ #include #include "usbvision-i2c.h" -static int debug = 0; +static int debug_i2c_usb = 0; #if defined(module_param) // Showing parameters under SYSFS -module_param (debug, int, 0444); // debug mode of the device driver +module_param (debug_i2c_usb, int, 0444); // debug_i2c_usb mode of the device driver #else -MODULE_PARM(debug, "i"); // debug mode of the device driver +MODULE_PARM(debug_i2c_usb, "i"); // debug_i2c_usb mode of the device driver #endif -MODULE_AUTHOR("Joerg Heckenbach"); -MODULE_DESCRIPTION("I2C algorithm for USB-I2C-bridges"); -MODULE_LICENSE("GPL"); - static inline int try_write_address(struct i2c_adapter *i2c_adap, unsigned char addr, int retries) @@ -71,7 +67,7 @@ static inline int try_write_address(struct i2c_adapter *i2c_adap, break; udelay(adap->udelay); } - if (debug) { + if (debug_i2c_usb) { if (i) { info("%s: Needed %d retries for address %#2x", __FUNCTION__, i, addr); info("%s: Maybe there's no device at this address", __FUNCTION__); @@ -98,7 +94,7 @@ static inline int try_read_address(struct i2c_adapter *i2c_adap, break; udelay(adap->udelay); } - if (debug) { + if (debug_i2c_usb) { if (i) { info("%s: Needed %d retries for address %#2x", __FUNCTION__, i, addr); info("%s: Maybe there's no device at this address", __FUNCTION__); @@ -170,7 +166,7 @@ usb_xfer(struct i2c_adapter *i2c_adap, struct i2c_msg msgs[], int num) pmsg = &msgs[i]; ret = usb_find_address(i2c_adap, pmsg, i2c_adap->retries, &addr); if (ret != 0) { - if (debug) { + if (debug_i2c_usb) { info("%s: got NAK from device, message #%d\n", __FUNCTION__, i); } return (ret < 0) ? ret : -EREMOTEIO; @@ -236,7 +232,7 @@ int usbvision_i2c_usb_add_bus(struct i2c_adapter *adap) i2c_add_adapter(adap); - if (debug) { + if (debug_i2c_usb) { info("i2c bus for %s registered", adap->name); } @@ -249,7 +245,7 @@ int usbvision_i2c_usb_del_bus(struct i2c_adapter *adap) i2c_del_adapter(adap); - if (debug) { + if (debug_i2c_usb) { info("i2c bus for %s unregistered", adap->name); } #ifdef MODULE -- 2.7.4
