The old async transmit context handling was starting and stopping DMA for every packet transmission. This could cause silently failing packet transmission, if the DMA was reprogrammed too close to being stopped. The general context code keeps DMA running at all times and fixes this problem. It's also a nice cleanup. Signed-off-by:

Drop the event list semaphore and only use the wait queue and the list to synchronize queue access. Break out of a poll or read whenever the device is disconnected. Signed-off-by:

The mod_timer based timing out of orb was a little to agressive and would time out legit, but long-lived scsi cmds. Besides, the scsi stack keeps track of this already. Since we're only timing out management orbs, go back to wait_for_completion_timeout. Signed-off-by:

The old mechanism kept a struct cdev for each fw device, but fops->release would reference this struct after the device got freed in some cases. Signed-off-by:

Repurpose the get_config_rom ioctl to a general get_info ioctl. This ioctl is now used for version negotiation, and optionally returns the config rom, and the current bus info. Signed-off-by:

We need the channel number as we queue up iso packets for transmission so we can fill out the header correctly. Signed-off-by:

When a DMA descriptor is appended to the context we sync it for DMA and the device might potentially read it immediately. So, we can't set the IRQ bits in the descriptor after appending. Signed-off-by:

When the DMA is setup to not strip any headers, we need to use the buffer fill descriptor instead of the dual buffer, since the dual buffer descriptor must strip a non-zero number of header quadlets. Signed-off-by:

This patch splits out the iso buffer so we can initialize it at mmap time with the size provided in the mmap call. Furthermore, allocate the backing pages using alloc_page to avoid setting up kernel side virtual memory mappings for the pages. Signed-off-by:

This prevents superfluous bus traffic as fw-sbp2 logs in only to get kicked off the device by another bus reset as the driver core does bus management. Scheduling it this way lets the driver core finish bus management before higher level drivers get the update callback. Signed-off-by:

Sometimes we reconnect too soon, sometimes too late. Adding a retry mechanism make the reconnect step much more robust. Signed-off-by:
