2009-09-10[SCSI] fcoe: move FIP controller from fcoe_port to fcoe_interfaceChris Leech
There is only one FIP state per net_device, so the FIP controller needs to be moved from the per-SCSI-host fcoe_port to the per-net_device fcoe_interface structure.

2009-09-10[SCSI] fcoe: move packet handlers from fcoe_port to fcoe_interfaceChris Leech
The packet handlers need to be tracked in fcoe_interface so there is only one set per net_device. When NPIV is enabled there will be multiple SCSI hosts and multiple fcoe_port structures on a single net_device. The packet handlers match by ethertype and netdev. If the same handler gets registered on a single netdev multiple times, the receive function will be called multiple times for each frame.

2009-09-10[SCSI] fcoe: move netdev to fcoe_interfaceChris Leech
The network interface needs to be shared between all NPIV VN_Ports, therefor it should be tracked in the fcoe_interface and not for each SCSI host in fcoe_port.

2009-09-10[SCSI] fcoe: Introduce and allocate fcoe_interface structure, 1:1 with ↵Chris Leech
net_device In preparation for NPIV support, I'm splitting the fcoe instance structure into two to remove the assumptions about it being 1:1 with the net_device. There will now be two structures, one which is 1:1 with the underlying net_device and one which is allocated per virtual SCSI/FC host. fcoe_softc is renamed to fcoe_port for the per Scsi_Host FCoE private data. Later patches with start moving shared stuff from fcoe_port to fcoe_interface Signed-off-by: Chris Leech <christopher.leech@intel.com> Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
2009-09-10[SCSI] fcoe: interface changes to fcoe_if_create and fcoe_if_destroyChris Leech
By passing in the parent device instead of assuming the netdev is what should be used, fcoe_if_create becomes usable for NPIV vports as well. You still need a netdev, because that's how FCoE works. Also removed some duplicate checks from fcoe_if_create that are already in fcoe_create. fcoe_if_destroy needs to take an lport as it's only argument, not a netdev. That removes the 1:1 netdev:lport assumption from the destroy path.

2009-09-10[SCSI] libfcoe: fcoe_ctlr_destroy use cancel_work_sync instead of flush_workChris Leech
Use cancel_work_sync() in place of flush_work(), so that fcoe_ctlr_destroy() can be called from a workqueue. Also, purge the receive queue after the recv_work has been cancled because if recv_work isn't run it's not guaranteed to be empty now.

2009-09-10[SCSI] fcoe: Add sysfs parameter to fcoe for minimum DDP read I/O sizeYi Zou
This adds fcoe_ddp_min as a module parameter for fcoe module to: /sys/module/fcoe/parameters/ddp_min It is observed that for some hardware, particularly Intel 82599, there is too much overhead in setting up context for direct data placement (DDP) read when the requested read I/O size is small. This is added as a module parameter for performance tuning and is set as 0 by default and user can change this based on their own hardware.

2009-09-10KVM: correct error-handling codeJulia Lawall
This code is not executed before file has been initialized to the result of calling eventfd_fget. This function returns an ERR_PTR value in an error case instead of NULL. Thus the test that file is not NULL is always true. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @match exists@ expression x, E; statement S1, S2; @@ x = eventfd_fget(...) ... when != x = E ( * if (x == NULL || ...) S1 else S2 | * if (x == NULL && ...) S1 else S2 ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Avi Kivity <avi@redhat.com>

2009-09-10KVM: VMX: Conditionally reload debug register 6Avi Kivity
Only reload debug register 6 if we're running with the guest's debug registers. Saves around 150 cycles from the guest lightweight exit path. dr6 contains a couple of bits that are updated on #DB, so intercept that unconditionally and update those bits then.

2009-09-10KVM: Use thread debug register storage instead of kvm specific dataAvi Kivity
Instead of saving the debug registers from the processor to a kvm data structure, rely in the debug registers stored in the thread structure. This allows us not to save dr6 and dr7. Reduces lightweight vmexit cost by 350 cycles, or 11 percent. Signed-off-by: Avi Kivity <avi@redhat.com>
2009-09-10KVM guest: do not batch pte updates from interrupt contextMarcelo Tosatti
Commit b8bcfe997e4 made paravirt pte updates synchronous in interrupt context. Unfortunately the KVM pv mmu code caches the lazy/nonlazy mode internally, so a pte update from interrupt context during a lazy mmu operation can be batched while it should be performed synchronously. https://bugzilla.redhat.com/show_bug.cgi?id=518022 Drop the internal mode variable and use paravirt_get_lazy_mode(), which returns the correct state.
