2008-11-04cx18: Move DVB buffer transfer handling from irq handler to work_queueAndy Walls
From: Andy Walls <awalls@radix.net> cx18: Move DVB buffer transfer handling from irq handler to work_queue thread. In order to properly lock the epu2cpu mailbox for driver to CX23418 commands, the DVB/TS buffer handling needs to be moved from the IRQ handler and IRQ context to a work queue. This work_queue implmentation is strikingly similar to the ivtv implementation - for better or worse. Priority: high Signed-off-by: Andy Walls <awalls@radix.net>
2008-11-04cx18: Use correct Mailbox IRQ Ack values and misc IRQ handling cleanupAndy Walls
From: Andy Walls <awalls@radix.net> cx18: Use correct Mailbox IRQ Ack values and misc IRQ handling cleanup. The SCB field definitions for Ack IRQ's for mailboxes were inconsistent with the bitmasks being loaded into those SCB fields and the SW2 Ack IRQ handling logic. Renamed fields in SCB to make things consistent and did misc IRQ handling cleanups: removing legacy ivtv dma_reg_lock, HPU IRQ flags, etc. Priority: high Signed-off-by: Andy Walls <awalls@radix.net>
2008-10-31cx18: Fix write retries for registers that always change - part 2.Andy Walls
From: Andy Walls <awalls@radix.net> cx18: Fix write retries for registers that always change - part 2. Some registers, especially interrupt related ones, will never read back the value just written. Modified interrupt register readback checks to make sure the intended effect was achieved. Priority: high Signed-off-by: Andy Walls <awalls@radix.net>
2008-10-25cx18: Disable write retries for registers that always change - part 1.Andy Walls
From: Andy Walls <awalls@radix.net> cx18: Disable write retries for registers that always change - part 1. Interrupt related registers will likely not read back the value we just wrote. Disable retries for these registers for now to avoid accidently discarding interrupts. More intelligent read back verification criteria are needed for these and other registers (e.g. GPIO line registers), which will be addressed in subsequent changes.

2008-10-04cx18: Fix warning message for DMA done notification for inactive stream.Andy Walls
From: Andy Walls <awalls@radix.net> cx18: Fix warning message for DMA done notification for inactive stream. The warning message would always gripe that the radio stream was to blame, which was misleading and wrong (/dev/radioN nodes never transfer data).

2008-08-30cx18: Create cx18_ specific wrappers for all pci mmio accessesors.Andy Walls
From: Andy Walls <awalls@radix.net> cx18: Create cx18_ specific wrappers for all pci mmio accessesors. This is a first step in instrumenting all CX23418 PCI bus IO, to debug problems with accessing the CX23418's PCI memory mapped IO. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
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>

2008-04-28cx18: 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!
