This causes problem with multipathing when the 'no_path_retry' setting exceeds the dev_loss_tmo setting, as then the system might run into a deadlock when all paths have been removed temporarily for longer than dev_loss_tmo. The principal reasons for the capping has been that we should not allow a remote port to remain in status 'blocked' indefinitely, so the capping is there to ensure that the port status is being reset eventually. However, the fast_io_fail_tmo will also move the remote port out of the 'blocked' state, so for any HBA driver implementing both the capping should really be on the fast_io_fail_tmo, and not on the dev_loss_tmo. This patch implements just that, ie the fast_io_fail_tmo is capped to SCSI_DEVICE_BLOCK_TIMEOUT and the capping is removed from dev_loss_tmo when fast_io_fail_tmo is set. This allows us to synchronize the dev_loss_tmo setting to the 'no_path_retry' setting from multipathing thus avoiding the deadlock.

So here's a better one. Also, force async with esp_set_offset() rather than esp_slave_configure(). One of the SCSI drives I tested still doesn't like the PIO mode and fails with "esp: esp0: Reconnect IRQ2 timeout" (the same drive works fine in PDMA mode). This failure happens when esp_reconnect_with_tag() tries to read in two tag bytes but the chip only provides one (0x20). I don't know what causes this. I decided not to waste any more time trying to fix it because the best solution is to rip out the PIO mode altogether and use the DMA engine.

An enhancement to the LSI Disk Array Controller firmware is being developed to look at the Head Of Queue bit to allow I/Os with the HOQ bit set to be processed before I/Os which do not have the HOQ bit set. In order to set the HOQ bit, the mpt fusion driver needs to look at the 'ioprio' field in the request structure associated with the scsi command.

This patch restores lpfc's ability to support MSI-X/MSI interrupts that the "Addition of SLI4 Interface - Base Support" patch [2] broke. It reestablishes MSI-X as the default interrupt method and in case MSI-X is not supported lpfc_sli{4,}_enable_intr fallbacks to MSI and then to INTx. [1]: http://bugs.gentoo.org/show_bug.cgi?id=296319 [2]: commit da0436e915a5c17ee79e72c1bf978a4ebb1cbf4d [James Smart: Background: Nothing Broke. This was intended. We had originally enabled MSI-X by default, but in qualification within the last 12 months, we encountered a major catch-22: There were at least 4 platforms, from 2 major OEMs, that : - Say they support MSI-X - platform routines work and act as if they do. - We enable it, generate a test interrupt to check they really do deliver it, and it works. - But shortly after attachment, the system hangs or loses interrupts, resulting in a bad system behavior. Given the distro's picking up the 2.6.32 kernel, we had to stick with a default of MSI-X off, with user-enabled MSI-X as these platforms couldn't get fixed. However, we're also now encountering platforms that require MSI-X and never INTx, so we must change. It's desired also for also for performance reasons. So - now (2.6.33) is the right time to re-enable MSI-X by default. ] [jejb: fix up comment on default values] Signed-off-by: George Kadianakis Acked-by: James Smart Signed-off-by: James Bottomley --- drivers/scsi/lpfc/lpfc_attr.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/scsi/lpfc/lpfc_attr.c b/drivers/scsi/lpfc/lpfc_attr.c index 91542f786edf..a8908e7c368a 100644 --- a/drivers/scsi/lpfc/lpfc_attr.c +++ b/drivers/scsi/lpfc/lpfc_attr.c @@ -3114,12 +3114,12 @@ LPFC_ATTR_RW(poll_tmo, 10, 1, 255, /* # lpfc_use_msi: Use MSI (Message Signaled Interrupts) in systems that # support this feature -# 0 = MSI disabled (default) +# 0 = MSI disabled # 1 = MSI enabled -# 2 = MSI-X enabled -# Value range is [0,2].

The driver hangs when doing `rmmod mpt2sas` if there are any IR volumes present.The hang is due the scsi midlayer trying to access the IR volumes after the driver releases controller resources. Perhaps when scsi_remove_host is called,the scsi mid layer is sending some request. This doesn't occur for bare drives becuase the driver is already reporting those drives deleted prior to calling mpt2sas_base_detach. To solve this issue, we need to delete the volumes as well.

Added new callbacks phy_enable and set_phy_speed in the mpt2sas_transport_functions template. This will allow end user to enable/disable phys and change links rates using the SysFS interface. Current implementation only supports direct attached phys, but we could in the future add support for expander based phys. A new subroutine mpt2sas_config_set_sas_iounit_pg1 was added; this wrapper function used to send request to controller firmware to modify the phys and link rates. A new subroutine _transport_find_local_phy was added; a function for easly obtaining the local phy object for direct attached.

If all Nports receive CVLs, then all timers are cancelled and a logical link level discovery will be started after one second. - Flush ELS commands after killing all delayed ELS commands.

Cameron" Date: Thu, 4 Feb 2010 08:43:41 -0600 Subject: [SCSI] hpsa: fix bug in adjust_hpsa_scsi_table fix bug in adjust_hpsa_scsi_table which caused devices which have changed size, etc. to do the wrong thing. The problem was as follows: The driver maintains its current idea of what devices are present in the h->dev[] array. When it updates this array, it scans the hardware, and produces a new list of devices, call it sd[], for scsi devices. Then, it compares each item in h->dev[] vs. sd[], and any items which are not present sd it removes from h->dev[], and any items present in sd[], but different, it modifies in h->dev[]. Then, it looks for items in sd[] which are not present in h->dev[], and adds those items into h->dev[]. All the while, it keeps track of what items were added and removed to/from h->dev[]. Finally, it updates the SCSI mid-layer by removing and adding the same devices it removed and added to/from h->dev[]. (modified devices count as a remove then add.) originally, when a "changed" device was discovered, it was removed then added to h->dev[]. The item was added to the *end* of h->dev[]. And, the item was removed from sd[] as well (nulled out). As it processed h->dev[], these newly added items at the end of the list were encountered, and sd[] was searched, but those items were nulled out. So they ended up getting removed immediately after they were added. The solution is to have a way to replace items in the h->dev[] array instead of doing a remove + add. Then the "changed" items. are not encountered a second time, and removed. Signed-off-by: Stephen M.

During initialization of one function its driver inhibits the ability of the other function's driver to allocate message frames by clearing its "active" flag. Should mid-layer error recovery be initiated for a scsi command during this initialization (which can take up to 40 seconds) error recovery will escalate to the level of host reset. This host reset might fail (as the other function is resetting) resulting in all connected targets being taken offline. This patch holds off mid-layer error recovery for up to 40 seconds to permit initialization of the other function to complete.

The idea is that the cmd probably timed out because we are trying to exeucte too many commands. If it turns out that the device the IO timedout on was bad or the cmd just got screwed up but other IO/devs were ok then we will will figure this out when the cmds ahead of the timed out one complete ok. This also fixes a bug where we were sort of detecting this by setting the last_timeout and last_xfer to the same value when the task was allocated. That caught the case where we never got to send any IO for it. However, if the problem had started right before we started the new task, then we were forced to wait an extra cmd timeout seconds to start the scsi eh.

We shouldn't allow the user to destroy connections by removing the module. We should force the user to destroy each connection and then the module can be removed. This patch makes it so a refrerence count on the module is taken each time a fcoe_interface is created. The reference count is dropped when the fcoe_interface is destroyed. This makes it so that module_exit() doesn't get called unless all fcoe_interfaces have been destroyed. This patch leaves the removal of interfaces in the module_exit routine so that if the user does a 'rmmod -f' we'll clean everything up before removing the module. The module_put line was put before the out_putdev goto line because we should only be decrementing the reference count if a fcoe_interface is actually destroyed. If we can't find the netdev or the fcoe_interface then it's assumed that something else has destroyed the fcoe_interface and it would have decremented the reference count at that time.
