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. Manually fix up conflicts in arch/x86_64/kernel/traps.c and drivers/char/ipmi/ipmi_watchdog.c.

2007-05-11Fix assertion failure with MSI on sparc64David Miller1-2/+4
Today's find is a triggered assertion in msi_free_irqs() when the system doesn't support MSI, in which case arch_setup_msi_irqs() always returns an error. The problem is that when this happens we branch into msi_free_irqs(), to which you added the following assertion loop: list_for_each_entry(entry, &dev->msi_list, list) BUG_ON(irq_has_action(entry->irq)); Well, if arch_setup_msi_irqs() fails, entry->irq will be zero and although that's never assigned to any normal devices we use that IRQ number for the timer interrupt on sparc64 so this assertion triggers. Better to test for zero before doing the irq_has_action() assertion thing. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-05-11libata: ignore EH scheduling during initializationTejun Heo2-0/+5
libata enables SCSI host during ATA host activation which happens after IRQ handler is registered and IRQ is enabled. All ATA ports are in frozen state when IRQ is enabled but frozen ports may raise limited number of IRQs after being frozen - IOW, ->freeze() is not responsible for clearing pending IRQs. During normal operation, the IRQ handler is responsible for clearing spurious IRQs on frozen ports and it usually doesn't require any extra code. Unfortunately, during host initialization, the IRQ handler can end up scheduling EH for a port whose SCSI host isn't initialized yet. This results in OOPS in the SCSI midlayer. This is relatively short window and scheduling EH for probing is the first thing libata does after initialization, so ignoring EH scheduling until initialization is complete solves the problem nicely. This problem was spotted by Berck E. Nash in the following thread. http://thread.gmane.org/gmane.linux.kernel/519412 Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Berck E.

2007-05-11libata: clean up SFF init messTejun Heo42-306/+308
The intention of using port_mask in SFF init helpers was to eventually support exoctic configurations such as combination of legacy and native port on the same controller. This never became actually necessary and the related code always has been subtly broken one way or the other. Now that new init model is in place, there is no reason to make common helpers capable of handling all corner cases. Exotic cases can simply dealt within LLDs as necessary. This patch removes port_mask handling in SFF init helpers. SFF init helpers don't take n_ports argument and interpret it into port_mask anymore. All information is carried via port_info. n_ports argument is dropped and always two ports are allocated. LLD can tell SFF to skip certain port by marking it dummy. Note that SFF code has been treating unuvailable ports this way for a long time until recent breakage fix from Linus and is consistent with how other drivers handle with unavailable ports. This fixes 1-port legacy host handling still broken after the recent native mode fix and simplifies SFF init logic. The following changes are made... * ata_pci_init_native_host() and ata_init_legacy_host() both now try to initialized whatever they can and mark failed ports dummy. They return 0 if any port is successfully initialized. * ata_pci_prepare_native_host() and ata_pci_init_one() now doesn't take n_ports argument. All info should be specified via port_info array. Always two ports are allocated. * ata_pci_init_bmdma() exported to be used by LLDs in exotic cases. * port_info handling in all LLDs are standardized - all port_info arrays are const stack variable named ppi. Unless the second port is different from the first, its port_info is specified as NULL (tells libata that it's identical to the last non-NULL port_info). * pata_hpt37x/hpt3x2n: don't modify static variable directly. Make an on-stack copy instead as ata_piix does. * pata_uli: It has 4 ports instead of 2. Don't use ata_pci_prepare_native_host(). Allocate the host explicitly and use init helpers. It's simple enough. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-05-11libata: implement libata.spindown_compatTejun Heo3-1/+34
Now that libata uses sd->manage_start_stop, libata spins down disk on shutdown. In an attempt to compensate libata's previous shortcoming, some distros sync and spin down disks attached via libata in their shutdown(8). Some disks spin back up just to spin down again on STANDBYNOW1 if the command is issued when the disk is spun down, so this double spinning down causes problem. This patch implements module parameter libata.spindown_compat which, when set to one (default value), prevents libata from spinning down disks on shutdown thus avoiding double spinning down. Note that libata spins down disks for suspend to mem and disk, so with libata.spindown_compat set to one, disks should be properly spun down in all cases without modifying shutdown(8). shutdown(8) should be fixed eventually. Some drive do spin up on SYNCHRONZE_CACHE even when their cache is clean. Those disks currently spin up briefly when sd tries to shutdown the device and then the machine powers off immediately, which can't be good for the head. We can't skip SYNCHRONIZE_CACHE during shudown as it can be dangerous data integrity-wise. So, this spindown_compat parameter is already scheduled for removal by the end of the next year and here's what shutdown(8) should do. * Check whether /sys/modules/libata/parameters/spindown_compat exists. If it does, write 0 to it. * For each libata harddisk { * Check whether /sys/class/scsi_disk/h:c:i:l/manage_start_stop exists. Iff it doesn't, synchronize cache and spin the disk down as before. } The above procedure will make shutdown(8) work properly with kernels before this change, ones with this workaround and later ones without it. To accelerate shutdown(8) updates, if the compat mode is in use, this patch prints BIG FAT warning for five seconds during shutdown (the optimal interval to annoy the user just the right amount discovered by hours of tireless usability testing).

Reimplement suspend/resume support using sdev->manage_start_stop. * Device suspend/resume is now SCSI layer's responsibility and the code is simplified a lot. * DPM is dropped. This also simplifies code a lot. Suspend/resume status is port-wide now. * ata_scsi_device_suspend/resume() and ata_dev_ready() removed. * Resume now has to wait for disk to spin up before proceeding. I couldn't find easy way out as libata is in EH waiting for the disk to be ready and sd is waiting for EH to complete to issue START_STOP. * sdev->manage_start_stop is set to 1 in ata_scsi_slave_config().
