2006-06-20[PATCH] sata_nv: kill not-working hotplug codeTejun Heo1-169/+0
sata_nv contained hotplug code which is mainly for demonstrating how hotplug event is handled. This patch kills the demo code in prepration for real hotplug implementation. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-06-17[PATCH] sky2: netconsole suspend/resume interactionStephen Hemminger1-1/+6
A couple of fixes that should prevent crashes when using netconsole and suspend/resume. First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.

2006-06-17[PATCH] fix cdrom openJens Axboe1-2/+4
Some time ago the cdrom open routine was changed so that we call the driver's open routine before checking to see if it is read only. However, if we discovered that a read write open was not possible and the open flags required a writable open, we just returned -EROFS without calling the driver's release routine. This seems to work for most cdrom drivers, but breaks the Powerpc iSeries virtual cdrom rather badly. This just inserts the release call in the error path to balance the call to "->open()" done by "open_for_data()".

2006-06-12[sky2] Fix sky2 network driver suspend/resumeLinus Torvalds1-0/+4
This fixes two independent problems: it would not save the PCI state on suspend (and thus try to resume a nonexistent state on resume), and while shut off, if an interrupt happened on the same shared irq, the irq handler would react very badly to the interrupt status being an invalid all-ones state.

2006-06-12[PATCH] libata: add host_set->next for legacy two host_sets case, take #3Tejun Heo2-2/+17
For a legacy ATA controller, libata registers two separate host sets. There was no connection between the two hosts making it impossible to traverse all ports related to the controller. This patch adds host_set->next which points to the second host_set and makes ata_pci_remove_one() remove all associated host_sets. * On device removal, all ports hanging off the device are properly detached. Prior to this patch, ports on the first host_set weren't detached casuing oops on driver unloading. * On device removal, both host_sets are properly freed This will also be used by new power management code to suspend and resume all ports of a controller. host_set/port representation will be improved to handle legacy controllers better and this host_set linking will go away with it.

2006-06-12[PATCH] sata_sil: update device hotplug handling, take #2Tejun Heo1-1/+19
SIEN on some 3112 controllers doesn't mask SATA IRQ properly. IRQ stays asserted even after SIEN is masked and IRQ is acked. Also, even while frozen, any SATA PHY event including hardreset raises SATA IRQ. Clearing SError seems to be the only way to deassert SATA IRQ. This patch makes sil_host_intr() clear SError on SATA IRQs and ignore SATA IRQs reported while frozen so that hardreset doesn't trigger hotplug event (which ends up hardresetting again). In such cases, the port still gets re-frozen to minimize the danger of screaming interrupts. This results in one nil EH repeat on controllers with broken SIEN but other than that does no harm.

2006-06-12[PATCH] Fix for the PPTP hangs that have been reportedPaul Mackerras1-1/+3
People have been reporting that PPP connections over ptys, such as used with PPTP, will hang randomly when transferring large amounts of data, for instance in http://bugzilla.kernel.org/show_bug.cgi?id=6530. I have managed to reproduce the problem, and the patch below fixes the actual cause. The problem is not in fact in ppp_async.c but in n_tty.c. What happens is that when pptp reads from the pty, we call read_chan() in drivers/char/n_tty.c on the master side of the pty. That copies all the characters out of its buffer to userspace and then calls check_unthrottle(), which calls the pty unthrottle routine, which calls tty_wakeup on the slave side, which calls ppp_asynctty_wakeup, which calls tasklet_schedule. So far so good. Since we are in process context, the tasklet runs immediately and calls ppp_async_process(), which calls ppp_async_push, which calls the tty->driver->write function to send some more output. However, tty->driver->write() returns zero, because the master tty->receive_room is still zero. We haven't returned from check_unthrottle() yet, and read_chan() only updates tty->receive_room _after_ calling check_unthrottle. That means that the driver->write call in ppp_async_process() returns 0. That would be fine if we were going to get a subsequent wakeup call, but we aren't (we just had it, and the buffer is now empty). The solution is for n_tty.c to update tty->receive_room _before_ calling the driver unthrottle routine. The patch below does this. With this patch I was able to transfer a 900MB file over a PPTP connection (taking about 25 minutes), whereas without the patch the connection would always stall in under a minute.
