| | | | | | | | | | | | | logging cx18: Adjust outgoing mailbox timeouts and remove statistics logging. This saves some wasted storage in struct cx18 for each card. Cutting the outgoing mailbox timeouts in half from the previous value appears to be safe with MythTV. Got rid of interrupted case code path after a wait uninterruptable returns.

| | | | | | | | | | | | | strategy cx18: Streamline cx18-io[ch] wrappers and enforce MMIO retry strategy so that write retries always occur and read retries never occur (as they never help). Remove MMIO statistics logging to speed up MMIO accesses. Deprecate & ignore retry_mmio and mmio_ndelay module parameters, to essentially force retry_mmio=1 and mmio_ndelay=0.

| | | | | | | | | | | | | work handler cx18: Propagate staleness of mailbox and mdl ack data to work handler to let the work handler know that the data from the encoder may not be coherent. Allows for smarter handling of buffers in future, to deal with MDLs that fall out of rotation due to irq handler being late in collecting mailbox and mdl ack info.

| | | | | | | | | | Convert the per stream queue spinlocks into mutexes. All queue manipulation happens via the work queue or system calls into the driver, and not in an interrupt context.

* V4L/DVB (9720): cx18: Major rewrite of interrupt handling for incoming ↵Andy Walls2008-12-3016-215/+408
| | | | | | | | | | | | | | | | | | mailbox processing A major rewrite of interrupt handling for incoming mailbox processing, to split the timing critical steps from the the deferrable steps as the sending XPU on the CX23418 will time out and overwrite our incoming mailboxes rather quickly. Setup a pool of work "order forms" for the irq handler to send jobs to the new work handler routine which uses the kernel default work queue to do the deferrable work. Started optimizing some of the cx18-io calls as they are now the low hanging fruit for recoving microseconds back from the timeline. Future optimizations will get rid of mmio read retries, mmio stats logging, and combine smaller functions in the irq path into the larger ones to save ~2 us each.

| | | | | | | | | | | | | interrupts to driver When the CX23418 CPU unit sent out an ack interrupt to the linux driver, it also received that interrupt and cleared the flag before the linux driver could see what the interrupt was for. This fix prevents the CPU from receiving an IRQ for it's own outgoing ack's to the linux driver. This fix is critical now that the linux driver doesn't poll but relies on these ack interrupts.

If the mailbox is still busy, force it free.

| | | | | | | | | | | | cx18: Reduce number of mmio read retries to improve performance. Experiments have shown 2 things: read retries never improve the result of a suspect mmio read from the CX23418 (the result stays all 0xff's), and that most of the suspected read failures are actually proper reads of values that should be all 0xff's.

| | | | | | | | | | | | | | | | | The previous patches removed XCLK and I2C magic. Now, we finally know what those registers do. Also, only a very few cards need different setups for those. Instead of keeping the setups for those values inside the per-device hack magic switch, move the uncommon values to the board-specific struct, and have a common setup for all other boards. So, almost 100 lines of hacking magic were removed. A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk were set, without taking any care about not overriding a previous xclk setup.
