2005-08-08[SCSI] drivers/scsi/st.c: add reference count and related fixesKai Makisara
I have rediffed the patch against 2.6.13-rc5, done a couple of cosmetic cleanups, and run some tests. Brian King has acknowledged that it fixes the problems he has seen. Seems mature enough for inclusion into 2.6.14 (or later)? Nate's explanation of the changes: I've attached patches against 2.6.13rc2. These are basically identical to my earlier patches, as I found that all issues I'd seen in earlier kernels still existed in this kernel. To summarize, the changes are: (more details in my original email) - add a kref to the scsi_tape structure, and associate reference counting stuff - set sr_request->end_io = blk_end_sync_rq so we get notified when an IO is rejected when the device goes away - check rq_status when IOs complete, else we don't know that IOs rejected for a dead device in fact did not complete - change last_SRpnt so it's set before an async IO is issued (in case st_sleep_done is bypassed) - fix a bogus use of last_SRpnt in st_chk_result Signed-off-by: Nate Dailey <nate.dailey@stratus.com> Signed-off-by: Kai Makisara <kai.makisara@kolumbus.fi> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-08[SCSI] aacraid: correct use of cmd->timeout fieldJames Bottomley
The cmd->timeout field has been obsolete for a while now. While looking to remove it, I came across this use in the aacraid driver. It looks like you want to initialise the firmware with the current timeout of the command (in seconds), so the value I think you should be using is cmd->timeout_per_command.

Received from Mark Salyzyn from Adaptec: This patch adds support for the new raw io command.

2005-08-05[SCSI] aacraid: aif registration timeout fixMark Haverkamp
Received from Mark Salyzyn from Adaptec: If the Adapter is quiet and does not produce an AIF event packets to be picked up by the management applications for longer than the timeout interval of two minutes, the cleanup code that deals with aging out registrants could erroneously drop the registration. The timeout is there to clean up should the management application die and fail to poll for updated AIF event packets. Moving the timer update from the ioctl code that delivers an AIF to the polling registrant to the bottom of the ioctl means the timeout is reset with any management application polling activity regardless if an AIF is delivered or not removing the erroneous timeout cleanups.

2005-08-05[SCSI] aacraid: interupt mitigationMark Haverkamp
Received from Mark Salyzyn from Adaptec: If more than two commands are outstanding to the controller, there is no need to notify the adapter via a PCI bus transaction of additional commands added into the queue; it will get to them when it works through the produce/consumer indexes. This reduced the PCI traffic in the driver to submit a command to the queue to near zero allowing a significant number of commands to be turned around with no need to block for the PCI bridge to flush the notify request to the adapter. Interrupt mitigation has always been present in the driver; it was turned off because of a bug that prevented one from realizing the usefulness of the feature. This bug is fixed in this patch.

2005-08-04[SCSI] aic79xx: fixup DT settingHannes Reinecke
this patch is just a cross-port of the fixup for aic7xxx DT settings. As the same restrictions apply for aic79xx also (DT requires wide transfers) the dt setting routine should be modified equivalently. And an invalid period setting will be caught by ahd_find_syncrate() anyway. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2005-08-03[SCSI] add missing hold_mcs parameter to the spi transport classJames Bottomley
This parameter is important only to people who take the time to tune the margin control settings, otherwise it's completely irrelevant. However, just in case anyone should want to do this, it's appropriate to include the parameter. I don't do anything with it in DV by design, so the parameter will come up as off by default, so if anyone actually wants to play with the margin control settings they'll have to enable it under the spi_transport class first. I also updated the transfer settings display to report all of the PPR settings instead of only DT, IU and QAS Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-03[SCSI] aic79xx: fix up transport settingsJames Bottomley
There's a slight problem in the way you've done the transport parameters; reading from the variables actually produces the current settings, not the ones you just set (and there's usually a lag because devices don't renegotiate until the next command goes over the bus). If you set the bit immediately, you get into the situation where the transport parameters report something as being set even if the drive cannot support it. I patched the driver to do it this way and also corrected a panic in the proc routines. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2005-07-29[PATCH] agp: restore APBASE after setting APSIZEMatthew Garrett
When leaving S3 state, the AGP bridge may not have all PCI configuration registers set in the same way as they were at boot. This should be fixed by pci_restore_state - however, the APBASE register cannot be set to conflict with the APSIZE register. If APSIZE is larger than it was before suspend, pci_restore_state will not restore APBASE correctly. The attached patch adds an extra item to the agp_bridge_data structure and uses it to store the value of APBASE. On resume, this is then written after APSIZE has been set. This patch only touches the path used for Intel chipsets without integrated graphics, and may need to be extended to work with the others. Without this patch, I get the symptoms described in bug 4921 - APBASE ends up overlapping various PCI devices, and as a result they fail to work after resume.

2005-07-29[PATCH] uml: fix vsyscall brokennessJeff Dike
The #if/#ifdef cleanup exposed a bug in UML's ELF header processing. With this bug fixed, UML recognizes the vsyscall info coming from the host. On FC4, there is a vsyscall page low in the address space, which UML doesn't provide. This causes an infinite page fault loop and a hang on boot.

2005-07-29[PATCH] x86: avoid wasting IRQs patch updateNatalie.Protasevich@unisys.com
The patch addresses a problem with ACPI SCI interrupt entry, which gets re-used, and the IRQ is assigned to another unrelated device. The patch corrects the code such that SCI IRQ is skipped and duplicate entry is avoided. Second issue came up with VIA chipset, the problem was caused by original patch assigning IRQs starting 16 and up. The VIA chipset uses 4-bit IRQ register for internal interrupt routing, and therefore cannot handle IRQ numbers assigned to its devices. The patch corrects this problem by allowing PCI IRQs below 16.

2005-07-29[PATCH] Fix sync_tsc hangEric W. Biederman
sync_tsc was using smp_call_function to ask the boot processor to report it's tsc value. smp_call_function performs an IPI_send_allbutself which is a broadcast ipi. There is a window during processor startup during which the target cpu has started and before it has initialized it's interrupt vectors so it can properly process an interrupt. Receveing an interrupt during that window will triple fault the cpu and do other nasty things. Why cli does not protect us from that is beyond me. The simple fix is to match ia64 and provide a smp_call_function_single. Which avoids the broadcast and is more efficient. This certainly fixes the problem of getting stuck on boot which was very easy to trigger on my SMP Hyperthreaded Xeon, and I think it fixes it for the right reasons.
