* [IA64] Fix irq migration in multiple vector domainKenji Kaneshige2008-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the problem that the following error message is sometimes displayed at irq migration when vector domain is enabled. "Unexpected interrupt vector %d on CPU %d is not mapped to any IRQ!" The cause of this problem is an interrupt is sent to the previous target CPU after cleaning up vector to irq mapping table. To clean up vector to irq map on the previous target CPU safty, change the irq migration in multiple vector domain as follows. The original idea is from x86 interrupt management code. - Delay vector to irq table cleanup until the interrupts are sent to new target CPUs. By this, it is ensured that target CPU is completely changed on the interrupt controller side. - Even after the interrupts are sent to new target CPUs, there can be pended interrupts remaining on the previous target CPU. So we need to delay clearning up vector to irq table until the pended interrupt is handled. For this, send IPI to the previous target CPU with lower priority vector and clean up vector to irq table in its handler. This patch affects only to irq migration code with multiple vector domain is enabled. Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

So we add this check to ia64_ia32 and improve it a liitle bit in that we need to check for stack overflow only when the signal is on stack.

It also tries to minimize the number of msrs switched according to the guest mode; for example, MSR_LSTAR is needed only by long mode guests. This optimization is done by setup_msrs(). However, we must not change which msrs are switched while we are running with guest msr state: - switch to guest msr state - call setup_msrs(), removing some msrs from the list - switch to host msr state, leaving a few guest msrs loaded An easy way to trigger this is to kexec an x86_64 linux guest. Early during setup, the guest will switch EFER to not include SCE. KVM will stop saving MSR_LSTAR, and on the next msr switch it will leave the guest LSTAR loaded. The next host syscall will end up in a random location in the kernel. Fix by reloading the host msrs before changing the msr list. Signed-off-by: Avi Kivity <avi@qumranet.com>
| * | KVM: MMU: Fix race when instantiating a shadow pteAvi Kivity2008-03-04

This means that we need to revalidate the guest ptes once we have write-protected the guest page tables, at which point they can no longer be modified. The current code attempts to avoid this check if the shadow page table is not new, on the assumption that if it has existed before, the guest could not have modified the pte without the shadow lock. However the assumption is incorrect, as the racing vcpu could have modified the pte, then instantiated the shadow page, before our vcpu regains control: vcpu0 vcpu1 fault walk pte modify pte fault in same pagetable instantiate shadow page lookup shadow page conclude it is old instantiate spte based on stale guest pte We could do something clever with generation counters, but a test run by Marcelo suggests this is unnecessary and we can just do the revalidation unconditionally. The pte will be in the processor cache and the check can be quite fast. Signed-off-by: Avi Kivity <avi@qumranet.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the use cases for the supported cpuid list is to create a "greatest common denominator" of cpu capabilities in a server farm. As such, it is useful to be able to get the list without creating a virtual machine first. Since the code does not depend on the vm in any way, all that is needed is to move it to the device ioctl handler. The capability identifier is also changed so that binaries made against -rc1 will fail gracefully. Signed-off-by: Avi Kivity <avi@qumranet.com>

| * | | cciss: remove READ_AHEAD define and use block layer defaultsMike Miller2008-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the #define READ_AHEAD 1024 from the driver and uses the block layer defaults, instead. We have found that under certain workloads the setting can cause a disk connected to the e200 controller to go offline. If the disk hiccups the link may try to downshift but the controller is never notified that the link successfully completed the renegotiation. We've also found that performance using the block layer default of 32 pages was on par with the 1024 setting. We tried setting it to zero at one time based on info from our firmware guys but that killed performance. Turns out we were talking about 2 different read ahead settings. Please consider this for inclusion. Signed-off-by: Mike Miller <mike.miller@hp.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
