After getting warnings in an allyesconfig build[1] from this driver, I decided to remind myself just how old it was, and whether it warranted fixing. In the Kconfig help text, I found: "This driver will eventually be phased out entirely" Going back to the history archive, I see the line was added[2] in Feb 2002, when we moved from v2.4.2.1 ---> v2.4.2.2 So, with over a decade of notification, and multiple major releases since then, I think we can justify removing this. Currently we have people wasting time building it during routine testing, and then wasting more time re-researching the known reported warnings, only to find that nobody really is willing to integrate the fixes[3] for it. A quick search didn't seem to indicate any active user base for it. If someone happens to have a quirky _old_ card that the eleven year old "new" driver doesn't work with, then it is entirely reasonable that they stick with a kernel version that predates this removal.

If we become disconnected from the PCI bus/PCIe fabric, there can be long delays in register reads which can cause erroneous decisions to be made and cause a soft lockup if a lock is held too long. As a preventative measure, check for a disconnection (register reads that return -1) and then disable the board if we find ourselves in this condition. For now, check in our interrupt handlers and the per adapter one second timer. Signed-off-by:

If the execute firmware command fails we do not stop the rest of the initialization process which will continue to fail so if we encounter an error simply short circuit the process. Signed-off-by:

If a fifo full condition is encountered, i/o requests will stack up in the h->reqQ queue. The only thing which empties this queue is start_io, which only gets called when new i/o requests come in. If none are forthcoming, i/o in h->reqQ will be stalled. To fix this, whenever fifo full condition is encountered, this is recorded, and the interrupt handler examines this to see if a fifo full condition was recently encountered when a command completes and will call start_io to prevent i/o's in h->reqQ from getting stuck. I've only ever seen this problem occur when running specialized test programs that pound on the the CCISS_PASSTHRU ioctl. Signed-off-by:

Cap CCISS_BIG_PASSTHRU as well. If an attempt is made to exceed this, ioctl() will return -1 with errno == EAGAIN. This is to prevent a userland program from exhausting all of pci_alloc_consistent memory. I've only seen this problem when running a special test program designed to provoke it. 20 concurrent commands via the passthru ioctls (not counting SG_IO) should be more than enough. Signed-off-by:

The hardware guys tell us that after initiating a software reset via the doorbell register we need to wait 5 seconds before attempting to talk to the board *at all*. This means that we cannot watch the board to verify it transitions from "ready" to to "not ready" then back "ready", since this transition will most likely happen during those 5 seconds (though we can still verify the reset happens by watching the "driver version" field get cleared.)

Migrate sr to make use of block layer runtime PM. Accordingly, the SCSI bus layer runtime PM callback is simplified as all SCSI drivers implementing runtime PM now use the block layer's request-based mechanism. Note that due to the device will be polled by kernel at a constant interval, if the autosuspend delay is set longer than the polling interval then the device will never suspend. Signed-off-by:

Instead of repeatedly calling driver_create_file() to create driver attribute files, This achieves the same thing by constructing an array of driver_attribute and setting it to bus_type->drv_groups. This change simplifies both creation and destruction of the attribute files, and also removes sparse warning caused by driver_attributes which are unnecessarily declared as global. Signed-off-by:

For NUMA systems, initializing the blk-mq layer and using per node hctx. We initialize submit queues to 1, while blk-mq nr_hw_queues is initialized to the number of NUMA nodes. This makes the null_init_hctx function overwrite memory outside of what it allocated. In my case it lead to writing garbage into struct request_queue's mq_map. Signed-off-by:
