From 914610e8c508224a6fb9fb501ed4bda25b340ba6 Mon Sep 17 00:00:00 2001 From: Ian Armstrong Date: Sat, 12 Jun 2010 13:33:21 -0300 Subject: V4L/DVB: ivtv: Add firmare monitoring and debug mode to ignore firmware problems >From Ian's e-mail: When a device is opened the firmware state will be checked. If it isn't responding then the open will fail with -EIO. Due to the nature of the hardware, a single failed check will block everything since we don't know exactly what has failed. A side effect of this is the blocking of debug access, so an additional debug level has been created which allows the block to be bypassed. Andy Walls' modifications: I modified Ian's patch to add a separate fw_debug module parameter to change the driver's behavior, as opposed to using the normal debug module parameter. The fw_debug module parameter is only available when CONFIG_VIDEO_ADV_DEBUG is set. I also made some minor whitespace adjustments and changed some warning messages to be a bit more specific. s/happy/glad/g Signed-off-by: Ian Armstrong Signed-off-by: Andy Walls Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/ivtv/ivtv-driver.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'drivers/media/video/ivtv/ivtv-driver.h') diff --git a/drivers/media/video/ivtv/ivtv-driver.h b/drivers/media/video/ivtv/ivtv-driver.h index 5b45fd2b264..c038dc8beb3 100644 --- a/drivers/media/video/ivtv/ivtv-driver.h +++ b/drivers/media/video/ivtv/ivtv-driver.h @@ -122,6 +122,9 @@ /* debugging */ extern int ivtv_debug; +#ifdef CONFIG_VIDEO_ADV_DEBUG +extern int ivtv_fw_debug; +#endif #define IVTV_DBGFLG_WARN (1 << 0) #define IVTV_DBGFLG_INFO (1 << 1) -- cgit v1.2.3-70-g09d2
