2014-08-05drm/radeon: Inline r100_mm_rreg, -wreg, v3Lauri Kasanen
This was originally un-inlined by Andi Kleen in 2011 citing size concerns. Indeed, a first attempt at inlining it grew radeon.ko by 7%. However, 2% of cpu is spent in this function. Simply inlining it gave 1% more fps in Urban Terror. v2: We know the minimum MMIO size. Adding it to the if allows the compiler to optimize the branch out, improving both performance and size. The v2 patch decreases radeon.ko size by 2%. I didn't re-benchmark, but common sense says perf is now more than 1% better. v3: Also change _wreg, make the threshold a define. Inlining _wreg increased the size a bit compared to v2, so now radeon.ko is only 1% smaller.

2014-08-05drm/radeon: enable display scaling on all connectors (v2)Alex Deucher
This enables the display scaler on all connectors for r5xx and newer asics. Previously we only enabled the scaler for fixed mode displays (eDP or LVDS) since they have to use the scaler to support non-native modes. Most other displays are multi-sync or have a built in scaler to support non-native modes. The default scaling mode for non-fixed displays is none which will use the scaler in the monitor. Note that we do not populate any fake modes like we do for fixed displays so it will only use the modes in the edid. For other modes, you'll need to populate them manually. bug: https://bugs.freedesktop.org/show_bug.cgi?id=80868 v2: properly handle scaling with no modes defined Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2014-08-05KVM: nVMX: Fix nested vmexit ack intr before load vmcs01Wanpeng Li
An external interrupt will cause a vmexit with reason "external interrupt" when L2 is running. L1 will pick up the interrupt through vmcs12 if L1 set the ack interrupt bit. Commit 77b0f5d (KVM: nVMX: Ack and write vector info to intr_info if L1 asks us to) retrieves the interrupt that belongs to L1 before vmcs01 is loaded. This will lead to problems in the next patch, which would write to SVI of vmcs02 instead of vmcs01 (SVI of vmcs02 doesn't make sense because L2 runs without APICv).

2014-08-05KVM: PPC: Enable IRQFD support for the XICS interrupt controllerPaul Mackerras
This makes it possible to use IRQFDs on platforms that use the XICS interrupt controller. To do this we implement kvm_irq_map_gsi() and kvm_irq_map_chip_pin() in book3s_xics.c, so as to provide a 1-1 mapping between global interrupt numbers and XICS interrupt source numbers. For now, all interrupts are mapped as "IRQCHIP" interrupts, and no MSI support is provided. This means that kvm_set_irq can now get called with level == 0 or 1 as well as the powerpc-specific values KVM_INTERRUPT_SET, KVM_INTERRUPT_UNSET and KVM_INTERRUPT_SET_LEVEL. We change ics_deliver_irq() to accept all those values, and remove its report_status argument, as it is always false, given that we don't support KVM_IRQ_LINE_STATUS. This also adds support for interrupt ack notifiers to the XICS code so that the IRQFD resampler functionality can be supported.

2014-08-05KVM: Give IRQFD its own separate enabling Kconfig optionPaul Mackerras
Currently, the IRQFD code is conditional on CONFIG_HAVE_KVM_IRQ_ROUTING. So that we can have the IRQFD code compiled in without having the IRQ routing code, this creates a new CONFIG_HAVE_KVM_IRQFD, makes the IRQFD code conditional on it instead of CONFIG_HAVE_KVM_IRQ_ROUTING, and makes all the platforms that currently select HAVE_KVM_IRQ_ROUTING also select HAVE_KVM_IRQFD.

2014-08-05KVM: Move irq notifier implementation into eventfd.cPaul Mackerras
This moves the functions kvm_irq_has_notifier(), kvm_notify_acked_irq(), kvm_register_irq_ack_notifier() and kvm_unregister_irq_ack_notifier() from irqchip.c to eventfd.c. The reason for doing this is that those functions are used in connection with IRQFDs, which are implemented in eventfd.c. In future we will want to use IRQFDs on platforms that don't implement the GSI routing implemented in irqchip.c, so we won't be compiling in irqchip.c, but we still need the irq notifiers. The implementation is unchanged.

2014-08-05KVM: Move all accesses to kvm::irq_routing into irqchip.cPaul Mackerras
Now that struct _irqfd does not keep a reference to storage pointed to by the irq_routing field of struct kvm, we can move the statement that updates it out from under the irqfds.lock and put it in kvm_set_irq_routing() instead. That means we then have to take a srcu_read_lock on kvm->irq_srcu around the irqfd_update call in kvm_irqfd_assign(), since holding the kvm->irqfds.lock no longer ensures that that the routing can't change. Combined with changing kvm_irq_map_gsi() and kvm_irq_map_chip_pin() to take a struct kvm * argument instead of the pointer to the routing table, this allows us to to move all references to kvm->irq_routing into irqchip.c. That in turn allows us to move the definition of the kvm_irq_routing_table struct into irqchip.c as well.
