2008-08-22cx18: Convert cx18_queue buffers member to atomic_tAndy Walls
From: Andy Walls <awalls@radix.net> cx18: Convert cx18_queue buffers member to atomic_t. This allows safe concurrent access to check if a queue has data without having to acquire the queue spinlock. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
2008-08-22cx18: Remove redundant struct cx18_queue length member.Andy Walls
From: Andy Walls <awalls@radix.net> cx18: Remove redundant struct cx18_queue length member. It can be trivially computed from queue->buffers * stream->buf_size, if ever really needed. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
2008-08-22cx18: Simplify queue flush logic to prevent oops in cx18_flush_queues()Andy Walls
From: Andy Walls <awalls@radix.net> cx18: Simplify queue flush logic to prevent oops in cx18_flush_queues(). If accounting of a queue is in error, logic borrowed from ivtv will cause an oops when flushing the queues for a stream. This change greatly simplifies the queue flush logic, and sets the queue back to sane defaults on a flush. Priority: high Signed-off-by: Andy Walls <awalls@radix.net>
2008-08-23v4l-dvb: fix a bunch of sparse warningsHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Fixed a lot of sparse warnings: mostly warnings about shadowed variables and signed/unsigned mismatches. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-08-17cx18: Add missing lock for when the irq handler manipulates the queuesAndy Walls
From: Andy Walls <awalls@radix.net> cx18: Add missing lock for when the irq handler manipulates the queues. This was a potential source of stream queue corruption. Also changed the name of cx18_queue_find_buf() to cx18_queue_get_buf_irq(). Priority: high Signed-off-by: Andy Walls <awalls@radix.net>
2008-05-05 cx18/: possible cleanupsMauro Carvalho Chehab
From: Adrian Bunk <bunk@kernel.org> This patch contains the following possible cleanups: - cx18-i2c.c should #include "cx18-i2c.h" for getting the prototypes of it's global functions - make the following needlessly global functions static: - cx18-fileops.c:cx18_claim_stream() - cx18-fileops.c:cx18_release_stream() - cx18-queue.c:cx18_queue_move() - remove the following unused functions: - cx18-driver.c:cx18_waitq() - cx18-queue.c:cx18_buf_copy_from_user() Signed-off-by: Adrian Bunk <bunk@kernel.org> Reviewed-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-05-01cx18/ivtv: improve and fix out-of-memory handlingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - don't show kernel backtrace when the allocation of the buffers fails: the normal ivtv/cx18 messages are clear enough and the backtrace scares users. - fix cleanup after the buffer allocation fails (caused kernel panic).

2008-04-28cx18: new driver for the Conexant CX23418 MPEG encoder chipHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Many thanks to Steve Toth from Hauppauge and Nattu Dakshinamurthy from Conexant for their support. I am in particular thankful to Hauppauge since without their help this driver would not exist. It should also be noted that Steve did the work to get the DVB part up and running. Thank you!
