* KVM: PPC: BookE: Load the lower half of MSRScott Wood2010-11-051-1/+1
| | | | | | | | This was preventing the guest from setting any bits in the hardware MSR which aren't forced on, such as MSR[SPE]. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
* KVM: PPC: BookE: fix sleep with interrupts disabledScott Wood2010-11-051-2/+0
| | | | | | | | | | | | It is not legal to call mutex_lock() with interrupts disabled. This will assert with debug checks enabled. If there's a real need to disable interrupts here, it could be done after the mutex is acquired -- but I don't see why it's needed at all.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When system uses 36bit physical address, res.start is 36bit physical address. But the function of in_be32 returns 32bit physical address. Then both of them compared each other is wrong. So by converting the address of res.start into the right format fixes this issue.

However, the device_control() portion of the DMA_SLAVE API is still useful to control device specific parameters, such as externally controlled DMA transfers and maximum burst length. A special dma_ctrl_cmd has been added to enable externally controlled DMA transfers. This is currently specific to the Freescale DMA controller, but can easily be made generic when another user is found. Signed-off-by: Ira W.

The conversion from cputime to the taskstats values uses the cputime_to_msecs primitive which effectively limits the granularity to milliseconds. Add the cputime_to_usecs primitive for architectures that have better, more precise CPU time values. Remove cputime_to_msecs primitive because there are no more users left.

Changes to the enumeration/discovery logic: 1. Use Master Enable bit to signal end of the enumeration - agents may start their discovery process as soon as they see this bit set (Component Tag register was used before for this purpose). 2. Enumerator sets Component Tag (!= 0) immediately during device setup. This allows to identify the device if the redundant route exists in a RIO system.

The problem is that we pop our stack slot before we're completely done resetting its state -- in particular clearing the PTE (sometimes that's CONFIG_DEBUG_HIGHMEM). If an interrupt happens before we actually clear the PTE used for the last slot, that interrupt can reuse the slot in a dirty state, which triggers a BUG in kmap_atomic(). Fix this by introducing kmap_atomic_idx() which reports the current slot index without actually releasing it and use that to find the PTE and delay the _pop() until after we're completely done.

The advantage is that we get rid of crappy code like: #define __KM_PTE \ (in_nmi() ? KM_NMI_PTE : \ in_irq() ? KM_IRQ_PTE : \ KM_PTE0) and in general can stop worrying about what context we're in and what kmap slots might be appropriate for that. The downside is that FRV kmap_atomic() gets more expensive. For now we use a CPP trick suggested by Andrew: #define kmap_atomic(page, args...) __kmap_atomic(page) to avoid having to touch all kmap_atomic() users in a single patch.

It also uses an unsafe shortcut for allocating the platform_device and the resource table at the same time. (which I added in the last rework; sorry). This patch refactors the code to use platform_device_alloc() for allocating new devices. This reduces the amount of custom code implemented by of_platform, eliminates the unsafe alloc trick, and has the side benefit of letting the platform_bus code manage freeing the device data and resources when the device is freed.

We get a notification from user space, telling us that an interrupt is there. But then user space expects us that we just acknowledge an interrupt once we deliver it to the guest. This is not how real hardware works though. On real hardware, the interrupt controller pulls the external interrupt line until it gets notified that the interrupt was received. So in reality we have two events: pulling and letting go of the interrupt line. To maintain backwards compatibility, I added a new request for the pulling part. The letting go part was implemented earlier already. With this in place, we can now finally start guests that do not randomly stall and stop to work at random times. This patch implements above logic for Book3S. Signed-off-by: Alexander Graf <agraf@suse.de>

Now, unfortunately we let that bit slip into the stored MSR value which is not what the real CPU does, so that we ended up executing code like this: r = mfmsr(); /* r containts MSR_POW */ mtmsr(r | MSR_EE); This obviously breaks, as we're going into idle mode in code sections that don't expect to be idling. This patch masks MSR_POW out of the stored MSR value on wakeup, making guests happy again. Signed-off-by: Alexander Graf <agraf@suse.de>
