From 3e082a910d217b2e7b186077ebf5a1126a68c62f Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Thu, 28 Sep 2006 15:19:20 -0600 Subject: [SCSI] Add ability to scan scsi busses asynchronously Since it often takes around 20-30 seconds to scan a scsi bus, it's highly advantageous to do this in parallel with other things. The bulk of this patch is ensuring that devices don't change numbering, and that all devices are discovered prior to trying to start init. For those who build SCSI as modules, there's a new scsi_wait_scan module that will ensure all bus scans are finished. This patch only handles drivers which call scsi_scan_host. Fibre Channel, SAS, SATA, USB and Firewire all need additional work.

So I decided to detangle the function and document what the valid cases are. While doing that I found that REQ_TYPE_SPECIAL commands aren't used by the SCSI layer anymore and we can get rid of the code handling them. The new structure of scsi_prep_fn is: (1) check if we're allowed to send this command (2) big switch on cmd_type. For the two valid types call into a function to set the command up, else error (3) code to handle error cases Because FS and BLOCK_PC commands are handled entirely separate after the patch this introduces a tiny amount of code duplication. This improves readabiulity though and will help to avoid the bidi command overhead for FS commands so it's a good thing. I've tested this on both sata and mptsas.

Like the earlier REQ_TASK_ABORT patch, this patch defers the device reset to the Scsi_Host's workqueue, which has the added benefit of ensuring that the device reset does not happen at the same time that the abort tmfs are being processed. After the phy reset, the busted drive should go away and be re-detected later, which is indeed what I've seen on both a x260 and a x206m. Signed-off-by: Darrick J.

This code is 'clunky' and does not have any real feedback in that the reset could progress before the user application has gotten it's notification of command completion. We put a schedule() call to delay just the right amount for most cases, because we tried a spin and still managed to find cases where we would spin forever waiting for the management application to acknowledge the impending doom surrounding the cause of the BlinkLED. Will cause an oops in the context of the management application if we proceed too quickly. I view this as the lesser of many evils since currently if there are outstanding management ioctls during a need to reset/recover the adapter, the management application just locks up and waits forever. The best practices fix for this problem not going to be simple or easy (at least the fixes I imagine today); and we found a balance between the needs of the driver to proceed, and the applications that locked or confused that would hold back the driver. I just do not like the idea of a kernel oops in an application to deal with low priority, sluggish or misbehaving applications.

Modify intialization semantics: - perform basic hardware configuration only (as usual) - allocate resources - load and execute firmware - defer link (transport) negotiations to the DPC thread - again the code in qla2x00_initialize_adapter() to stall probe() completion was needed for legacy-style scanning. - DPC thread stalls until probe() complete. - before probe() completes, set DPC flags to perform loop-resync logic (similar to what's done during cable-insertion/removal). Benefits: user does not have to wait 20+ seconds in case the FC cable is unplugged during driver load, code consolidation (removal of redundant link negotiation logic during initialize_adaoter()), and finilly, the driver no longer needs to defer the fc_remote_port_add() calls to hold off lun-scanning prior to returning from the probe() function.

Note, per the last review we moved almost all the fields we added to the scsi_cmnd to our internal data structure which we are going to try and kill off when we can replace it with support from other parts of the kernel. The one field we left on was the offset variable. This is needed to handle the case where the target gets request that is so large that it cannot execute it in one dma operation. So max_secotors or a segment limit may limit the size of the transfer. In this case our tgt core code will break up the command into managable transfers and send them to the LLD one at a time. The offset is then used to tell the LLD where in the command we are at. Is there another field on the scsi_cmd for that?

This patch adds shared memory interface between kernel and user spaces like some other drivers do by using own character device. The user-space daemon and tgt kernel module creates shared memory via mmap and use it like ring buffer. poll (kernel to user) and write (user to kernel) system calls are used for notification.

Also, a CIS override autoloaded using the firmware loader may allow for the use of more or less functions in a multifunction card. Therefore, we may need to schedule a call to add this second function later on, or simply remove the other function (it's always the first -valid- function which reaches this codepath).

The changes include: - Use the I/O memory address passed via the platform_device resources instead of constant global values. - The IRQ should not be used as a random'ness source. - Return errors if ioremap() or request_mem_region() fails.

This throws a warning, but is otherwise OK because the 'unsigned long' is really the result of ioremap(). This setup is also OK because the variable can hold an ioremap cookie /or/ a PCI I/O port (PIO). However, to fix the warning thrown when readl() and writel() are passed an unsigned long cookie, I introduce 'void __iomem *mmio_base', holding the same value as 'base'. This will silence the warnings, and also cause an oops whenever these MMIO-only functions are ever accidentally passed an I/O address.
