* [SCSI] Reduce error recovery time by reducing use of TURsDavid Jeffery2011-05-241-20/+67
| | | | | | | | | | | | | | | | | | | | | In error recovery, most scsi error recovery stages will send a TUR command for every bad command when a driver's error handler reports success. When several bad commands to the same device, this results in a device being probed multiple times. This becomes very problematic if the device or connection is in a state where the device still doesn't respond to commands even after a recovery function returns success. The error handler must wait for the test commands to time out. The time waiting for the redundant commands can drastically lengthen error recovery. This patch alters the scsi mid-layer's error routines to send test commands once per device instead of once per bad command. This can drastically lower error recovery time.

* [SCSI] Retrieve the Caching mode page (version 2)Luben Tuikov2011-05-241-18/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some kernel transport drivers unconditionally disable retrieval of the Caching mode page. One such for example is the BBB/CBI transport over USB. Such a restraint is too harsh as some devices do support the Caching mode page. Unconditionally enabling the retrieval of this mode page over those transports at their transport code level may result in some devices failing and becoming unusable. This patch implements a method of retrieving the Caching mode page without unconditionally enabling it in the transports which unconditionally disable it. The idea is to ask for all supported pages, page code 0x3F, and then search for the Caching mode page in the mode parameter data returned. The sd driver already asks for all the mode pages supported by the attached device by setting the page code to 0x3F in order to find out if the media is write protected by reading the WP bit in the Device Specific Parameter field. It then attempts to retrieve only the Caching mode page by setting the page code to 8 and actually attempting to retrieve it if and only if the transport allows it. The method implemented here is that if the transport doesn't allow retrieval of the Caching mode page and the device is not RBC, then we ask for all pages supported by setting the page code to 0x3F (similarly to how the WP bit is retrieved above), and then we search for the Caching mode page in the mode parameter data returned. With this patch, devices over SATA, report this (no change): Oct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] 976773168 512-byte logical blocks: (500 GB/465 GiB) Oct 22 18:45:58 localhost kernel: sd 0:0:0:0: Attached scsi generic sg0 type 0 Oct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] Write Protect is off Oct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 Oct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Smart devices report their Caching mode page.

* [SCSI] bnx2i: Optimized the iSCSI offload performanceEddie Wai2011-05-243-19/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modified the event coalescing code for iSCSI offload to combat both corner cases and optimize performance as follows: 1. Added mechanism to loop back a second time to process any leftover CQEs that was generated by the hardware during the time the driver is busy processing previous CQEs in the bh. This not only helps the performance but also fixes the corner case when no more CQEs are being generated in the pipeline; so those leftover CQEs will get a a chance to be processed. 2. Added ARM_CQE_FP to distinguish between fast path arming versus slow path arming. This change will guarantee that the CQEs will always get a chance to be re-armed during fast path completions. 3. Removed the inline event coalescing division for perf optimization. Also fixed a division-by-zero error when the event_coal_div module param was set to 0. 4. Changed the default SQ WQEs size from 256 to 128 to match chip default. 5. Changed the cmd_per_lun from 32 to 24.

* [SCSI] bnx2i: Fixed packet error created when the sq_size is set to 16Eddie Wai2011-05-242-0/+4
| | | | | | | | | | | | | | The number of chip's internal command cell, which is use to generate SCSI cmd packets to the target, was not initialized correctly by the driver when the sq_size is changed from the default 128. This, in turn, will create a problem where the chip's transmit pipe will erroneously reuse an old command cell that is no longer valid. The fix is to correctly initialize the chip's command cell upon setup.

* [SCSI] ipr: fix possible false positive detection of stuck interruptWayne Boyer2011-05-241-6/+6
| | | | | | | | | | | | | | | | If the driver is getting flooded with interrupts, there's a possibility that the interrupt service routine could falsely detect a stuck interrupt condition and reset the adapter. This patch changes the logic such that the routine will loop back into the command processing code one more time after detecting the stuck interrupt signature. If there are no commands to process after that pass, and the interrupt is still not cleared, then the driver will print the "Error clearing HRRQ" message and reset the adapter.

* [SCSI] libfcoe: Remove unnecessary module state checksRobert Love2011-05-241-40/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libfcoe's interface consists of create, destroy, enable, disable and create_vn2vn. These are currently module paramaters added durring the module initialization. A concern arose that the module parameters were being added with write permissions before the module had completed initialization. The following code was added to each sysfs store file. * Make sure the module has been initialized, and is not about to be * removed. Module parameter sysfs files are writable before the * module_init function is called and after module_exit. */ if (THIS_MODULE->state != MODULE_STATE_LIVE) goto out_nodev; This check was called out as unhelpful as the module can go dead at any time and therefore its state isn't a reliable thing to look at as a sign of stability and initialization completion. Also, that functional interfaces like these should be added after module initialization. This patch removes the unnecessary checks and hopes to disprove the concern about initialization ordering. Recent fcoe transport rework changes now require fcoe transports to register with libfcoe before any operation can take place. libfcoe may access some static variables but nothing that could cause a problem. Once a fcoe transport is registered, libfcoe is usable and any interface calls will be functional.

| * | | ethtool: Call ethtool's get/set_settings callbacks with cleaned dataDavid Decotigny2011-04-292-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes sure that when a driver calls the ethtool's get/set_settings() callback of another driver, the data passed to it is clean. This guarantees that speed_hi will be zeroed correctly if the called callback doesn't explicitely set it: we are sure we don't get a corrupted speed from the underlying driver. We also take care of setting the cmd field appropriately (ETHTOOL_GSET/SSET). This applies to dev_ethtool_get_settings(), which now makes sure it sets up that ethtool command parameter correctly before passing it to drivers. This also means that whoever calls dev_ethtool_get_settings() does not have to clean the ethtool command parameter. This function also becomes an exported symbol instead of an inline. All drivers visible to make allyesconfig under x86_64 have been updated. Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
