2007-05-16libata: track spindown status and skip spindown_compat if possibleTejun Heo1-0/+9
Our assumption that most distros issue STANDBYNOW seems wrong. The upstream sysvinit and thus many distros including gentoo and opensuse don't take any action for libata disks on spindown. We can skip compat handling for these distros so that they don't need to update anything to take advantage of kernel-side shutdown.

2007-05-16libata: fix shutdown warning message printingTejun Heo1-8/+27
Unlocking ap->lock and ssleeping don't work because SCSI commands can be issued from completion path without context. Reimplement delayed completion by allowing translation functions to override qc->scsidone(), storing the original completion function to scmd->scsi_done() and overriding qc->scsidone() with a function which schedules delayed invocation of scmd->scsi_done(). This isn't pretty at all but all the ugly parts are thankfully contained in the stop translation path where the compat feature is implemented.

2007-05-16libata-acpi: add ATA_FLAG_ACPI_SATA port flagTejun Heo3-7/+9
Whether a controller needs IDE or SATA ACPI hierarchy is determined by the programming interface of the controller not by whether the controller is SATA or PATA, or it supports slave device or not. This patch adds ATA_FLAG_ACPI_SATA port flags which tells libata-acpi that the port needs SATA ACPI nodes, and sets the flag for ahci and sata_sil24.

2007-05-16libata: during revalidation, check n_sectors after device is configuredTejun Heo1-18/+15
Device might be resized during ata_dev_configure() due to HPA or (later) ACPI _GTF. Currently it's worked around by caching n_sectors before turning off HPA. The cached original size is overwritten if the device is reconfigured without being hardreset - which always happens after configuring trasnfer mode. If the device gets hardreset for some reason after that, revalidation fails with -ENODEV. This patch makes size checking more robust by moving n_sectors check from ata_dev_reread_id() to ata_dev_revalidate() after the device is fully configured. No matter what happens during configuration, a device must have the same n_sectors after fully configured to be treated as the same device.

2007-05-16libata: separate out ata_dev_reread_id()Tejun Heo2-14/+36
Separate out ata_dev_reread_id() from ata_dev_revalidate(). ata_dev_reread_id() reads IDENTIFY page and determines whether the same device is still there. ata_dev_revalidate() reconfigures after reread completes. This will be used by ACPI update. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-05-15[SPARC64]: Add hypervisor API negotiation and fix console bugs.David S. Miller1-71/+205
Hypervisor interfaces need to be negotiated in order to use some API calls reliably. So add a small set of interfaces to request API versions and query current settings. This allows us to fix some bugs in the hypervisor console: 1) If we can negotiate API group CORE of at least major 1 minor 1 we can use con_read and con_write which can improve console performance quite a bit. 2) When we do a console write request, we should hold the spinlock around the whole request, not a byte at a time. What would happen is that it's easy for output from different cpus to get mixed with each other. 3) Use consistent udelay() based polling, udelay(1) each loop with a limit of 1000 polls to handle stuck hypervisor console.

This patch is based on the documentation (I would like to thank Promise for it) and also partially on the older vendor driver. Rewrite mode programming code: * disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled even if both devices on the channel are not DMA capable and after reset * enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset() as they need to be setup correctly also for PIO only devices, plus IORDY wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for ATAPI devices * remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma() (driver sets ->autotune to 1 so PIO modes are always programmed => lower nibble of register A never equals 4 => "chipset_is_set" is always true) * enable PIO mode programming for all ATAPI devices (it was limited to ->media == ide_cdrom devices) * remove extra reads of registers A/B/C, don't read register D et all * do clearing / programming of registers A/B/C in one go (gets rid of extra PCI config space read/write cycle) * set initial values of drive_conf/AP/BP/CP variables to zero (paranoia for the case when PCI reads fail) * remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen (ide_rate_filter() takes care of it) * fix XFER_MW_DMA0 timings (they were overclocked, use the official ones) * fix bitmasks for clearing bits of register B: - when programming DMA mode bit 0x10 of register B was cleared which resulted in overclocked PIO timing setting (iff PIO0 was used) - when programming PIO mode bits 0x18 weren't cleared so suboptimal timings were used for PIO1-4 if PIO0 was previously set (bit 0x10) and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08) * add FIXME comment about missing locking for 66MHz clock register Also while at it: * remove unused defines * do a few cosmetic / CodingStyle fixes * bump driver version v2: * in pdc202xx_tune_chipset() the old content of drive configuration registers is used only by the debugging code so cover "drive_conf" PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO (Noticed by Sergei Shtylyov) Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-05-14Revert "ipmi: add new IPMI nmi watchdog handling"Linus Torvalds1-92/+42
This reverts commit f64da958dfc83335de1d2bef9d3868f30feb4e53. Andi Kleen is unhappy with the changes, and they really do not seem worth it. IPMI could use DIE_NMI_IPI instead of the new callback, even though that ends up having its own set of problems too, mainly because the IPMI code cannot really know the NMI was from IPMI or not.

2007-05-14RDMA/cma: Fix synchronization with device removal in cma_iw_handlerSean Hefty1-2/+3
The cma_iw_handler needs to validate the state of the rdma_cm_id before processing a new connection request to ensure that a device removal is not already being processed for the same rdma_cm_id. Without the state check, the user can receive simultaneous callbacks for the same cm_id, or a callback after they've destroyed the cm_id.

2007-05-14IB/ehca: Beautify sysfs attribute code and fix compiler warningsJoachim Fenkes1-49/+37
eHCA's sysfs attributes are now being created via sysfs_create_group(), making the process neatly table-driven. The return value is checked, thus fixing a few compiler warnings. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
