| * | [SCSI] bnx2fc: Map the doorbell register between offload and enable requestsBhanu Prakash Gollapudi2013-01-303-28/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to map doorbell register after FW enable request is complete. This causes a race condition when unsolicited event is received, and FW sends a CQE for it. Since the doorbell is not mapped, driver does not arm CQ, which means FW will not notify the driver for further CQ completions. To resolve this, map the doorbell between offload and enable, so that driver is ready to receive the unsolicited packets and arm the CQ as soon as FW enable is performed.

There is a cut and paste error here and SL_WH_EVENT_TRIGGERS_T is used instead of SL_WH_MPI_TRIGGERS_T.

Events:- 1. Mailbox interrupts are disabled 2. FW generates AEN and at same time driver enables Mailbox Interrupt 3. Driver issues new mailbox to Firmware In above case driver will not get AEN interrupts generated by FW in step #2 as FW generated this AEN when interrupts are disabled. During the same time driver enabled the mailbox interrupt, so driver will not poll for interrupt. Driver will never process AENs generated in step #2 and issues new mailbox to FW, but now FW is not able to post mailbox completion as AENs generated before are not processed by driver. Fix: Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX. This will make sure we process all Mailbox and AENs in interrupt mode.

| * | [SCSI] gdth: Remove buggy ROM handlingBjorn Helgaas2013-01-291-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ROM address handling in gdth_init_pci() is useless and possibly dangerous. This patch removes it. "pci_resource_start(pdev, 8)" is not well-defined. PCI resources 0-5 are standard PCI BARs and 6 is the expansion ROM. Resource 8 is either an SR-IOV BAR (if CONFIG_PCI_IOV=y, resources 7-12 are SR-IOV BARs) or a bridge window (resources 7-10). The GDT device is neither an SR-IOV device nor a bridge, so in either case resource 8 should be zero since struct pci_dev is allocated with kzalloc(). It is illegal for a driver to write an arbitrary address to the ROM BAR because it has no way of knowing whether the ROM will conflict with another device. I think the only effect of the code being removed was to: 1) Enable the ROM at 0xFEFF0000 (possibly causing a conflict with another device) 2) Delay one millisecond 3) Write zero to the ROM BAR, disabling it I doubt the delay is needed, but I left it since it seems innocuous.

Discussion was continuing after patch application, trying to figure out how to best mesh exported data with the installers, boot-time agents and other parties that want this info. 2) Merge Zero-Power Optical Device Driver (ZPODD) support, bringing the wonderfulness of sane power management to your CD/DVD device. Includes one SCSI-subsystem patch (with appropriate ACKs), adding runtime PM support to 'sr' driver. That is the ZPODD interaction bits. Patchset went through some 13 revisions before it got here; kudos to Intel for persistence. 3) pata_samsung_cf: use devm_clk_get() 4) more ata_piix, ahci PCI IDs 5) Add SATA driver for R-Car SoC 6) Convert libata to use devm_ioremap_resource (Note: I think Greg sent this to you, also) 7) Set proper Sense Key (SK) in the SCSI simulator when ATA passthrough indicates check condition. Google and specification hawks everywhere shall rejoice. * tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev: (22 commits) [libata] fix smatch warning for zpodd_wake_dev [libata] Set proper SK when CK_COND is set.

| * | | [libata] scsi: no poll when ODD is powered offAaron Lu2013-01-252-3/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the ODD is powered off, any action the user did to the ODD that would generate a media event will trigger an ACPI interrupt, so the poll for media event is no longer necessary. And the poll will also cause a runtime status change, which will stop the ODD from staying in powered off state, so the poll should better be stopped. But since we don't have access to the gendisk structure in LLDs, here comes the disk_events_disable_depth for scsi device. This field is a hint set by LLDs to convey information to upper layer drivers. A value of 0 means media poll is necessary for the device, while values above 0 means media poll is not needed and should better be skipped. So we can increase its value when we are to power off the ODD in ATA layer and decrease its value when the ODD is powered on, effectively silence the media events poll.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds runtime pm support for sr. It did this by increasing the runtime usage_count of the device when its block device is accessed. And decreasing the runtime usage_count of the device when the access is done. If there is media inside, runtime suspend is not allowed as we don't always know if the ODD is being used or not. The idea is discussed here: http://thread.gmane.org/gmane.linux.acpi.devel/55243/focus=52703 and the restriction to check media inside is discussed here: http://thread.gmane.org/gmane.linux.ide/53665/focus=58836 Signed-off-by: Aaron Lu <aaron.lu@intel.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
