* KVM: kvmtrace: replace get_cycles with ktime_get v3Christian Ehrhardt2008-10-152-12/+13
| | | | | | | | | | | | | The current kvmtrace code uses get_cycles() while the interpretation would be easier using using nanoseconds. ktime_get() should give at least the same accuracy as get_cycles on all architectures (even better on 32bit archs) but at a better unit (e.g. comparable between hosts with different frequencies.

* KVM: kvmtrace: Remove use of bit fields in kvm trace structureChristian Ehrhardt2008-10-152-11/+23
| | | | | | | | | | | This patch fixes kvmtrace use on big endian systems. When using bit fields the compiler will lay data out in the wrong order expected when laid down into a file. This fixes it by using one variable instead of using bit fields.

* KVM: VMX: Reinject real mode exceptionJan Kiszka2008-10-152-2/+43
| | | | | | | | | | | | | | | | | | | | As we execute real mode guests in VM86 mode, exception have to be reinjected appropriately when the guest triggered them. For this purpose the patch adopts the real-mode injection pattern used in vmx_inject_irq to vmx_queue_exception, additionally taking care that the IP is set correctly for #BP exceptions. Furthermore it extends handle_rmode_exception to reinject all those exceptions that can be raised in real mode. This fixes the execution of himem.exe from FreeDOS and also makes its debug.com work properly. Note that guest debugging in real mode is broken now. This has to be fixed by the scheduled debugging infrastructure rework (will be done once base patches for QEMU have been accepted).

* KVM: VMX: Move interrupt post-processing to vmx_complete_interrupts()Avi Kivity2008-10-151-57/+20
| | | | | | | | Instead of looking at failed injections in the vm entry path, move processing to the exit path in vmx_complete_interrupts(). This simplifes the logic and removes any state that is hidden in vmx registers. Signed-off-by: Avi Kivity <avi@qumranet.com>

* KVM: VMX: Fix pending exception processingAvi Kivity2008-10-151-3/+12
| | | | | | | | | | | | | The vmx code assumes that IDT-Vectoring can only be set when an exception is injected due to the exception in question. That's not true, however: if the exception is injected correctly, and later another exception occurs but its delivery is blocked due to a fault, then we will incorrectly assume the first exception was not delivered. Fix by unconditionally dequeuing the pending exception, and requeuing it (or the second exception) if we see it in the IDT-Vectoring field. Signed-off-by: Avi Kivity <avi@qumranet.com>

* KVM: VMX: Move nmi injection failure processing to vm exit pathAvi Kivity2008-10-152-17/+33
| | | | | | | | | | Instead of processing nmi injection failure in the vm entry path, move it to the vm exit path (vm_complete_interrupts()). This separates nmi injection from nmi post-processing, and moves the nmi state from the VT state into vcpu state (new variable nmi_injected specifying an injection in progress).

This specific test just requires that bus_register(&i2c_bus_type) was called.

| * i2c-parport-light: Don't register a platform device resourceJean Delvare2008-10-141-31/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The i2c-parport-light driver isn't a real platform driver, so it should not instantiate platform devices with resources. The resource management system can't cope with colliding resources, and we are likely to create such a colliding resource. So, better just try to grab the I/O ports we need right at module initialization time, and bail out if we can't. It has the added benefit that the module will no longer load if it isn't going to work, which is definitely more user-friendly. Signed-off-by: Jean Delvare <khali@linux-fr.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The dme1737 driver support both LPC (ISA) and SMBus devices. At the moment it's rather i2c-centric, and LPC variants use a fake i2c_client for some operations. In a near future, i2c_client will be allocated by i2c-core rather than by the device drivers, so non-i2c drivers will not have one. As a preparation step, change the driver code to no longer assume that an i2c_client structure is always available. No functional change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Grabbing ISA bus resources without anything or anyone telling us we should can break boot on randconfig/allyesconfig builds by keeping resources that are in fact owned by different hardware busy and does as reported by Ingo Molnar. Generally it's also dangerous to just poke at random I/O ports and especially those in the range where other old easily confused ISA hardware might live. For this specialized I2C bus driver, insist that the user specifies the resources before grabbing them. The^WA user of this driver is a one time echo "options i2c-pca-isa base=0x330 irq=10" >> /etc/modprobe.conf away from the old behaviour.

However, the hid-pidff driver sleeps when handling events as it waits for reports being sent to the device before changing the report contents again. This causes a system lockup when trying to use force feedback with a PID device, a regression introduced in 2.6.24 and 2.6.23.15. Fix it by extracting the raw report data from struct hid_report immediately when hid_submit_report() is called, therefore allowing drivers to change the contents of struct hid_report immediately without affecting the already-queued transfer. In hid-pidff, re-add the removed usbhid_wait_io() to pidff_erase_effect() instead, to prevent a full report queue from causing the submission to fail, thus not freeing up device memory. pidff_erase_effect() is not called while dev->event_lock is held.
