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.

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:

since this card can support the setting, add it to the parameter list. Signed-off-by: -
James Bottomley authored
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: -

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: -

This patch updates the aic79xx driver to take advantage of the scsi_transport_spi infrastructure. Patch is quite a mess as some procedures have been reshuffled to be closer to the aic7xxx driver. Rejections fixed and Signed-off-by: -

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. Signed-off-by:

Close a small window where a device may be not operational again after senseid finished and the "same device" check fails due to dev=0000 by checking for dnv after stsch() by then setting the device to not operational. (No need to check for dnv in ccw_device_handle_oper() again since we don't do stsch() into the subchannel's schib in the meantime and will get a crw anyway if the device becomes not oper again).

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. This patch works around that by making this look like a no-vsyscall system. Signed-off-by:

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.

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.

This patch does the same swap, i.e. use the ISO macro if (isoc). Additionally, it fixes the return value - the usb_calc_bus_time function returns the time in nanoseconds (I didn't notice that before) while the HS_USECS and HS_USECS_ISO are microseconds. This fixes the function to return nanoseconds always, and adjusts ehci-q.c (the only high-speed caller of the function) to wrap the call in NS_TO_US(). Signed-off-by:
