Subject: [patch][Intel-IOMMU] Fix for IOMMU early crash
pci_dev's->sysdata is highly overloaded and currently
IOMMU is broken due to IOMMU code depending on this field.
This patch introduces new field in pci_dev's struct to
hold IOMMU specific per device IOMMU private data.

Hi,
We observe a problem with MSI since kernel 2.6.21 where interrupts would
randomly stop working. We have tracked it down to the new
msi_set_mask_bit definition in 2.6.21. In the MSI case with a device not
providing a "native" MSI mask, it was a no-op before, and now it
disables MSI in the

I ran your original preemption test of RCU torture, and after several
minutes, my preempt boost patch had one Preemption stall. I then
disabled preemption boosting, and ran the preempt torture again, and it
seemed to never stall. Something seemed strange, so I took a look.
Looks like you
Added module parameter "poll_mode_io" to support for "polling" (reduced
interrupt operation).
In this mode, IO completion interrupts are delayed. At the end of
initiating IOs, the
driver schedules for cmd completion if there are pending cmds. A
