x86/vsmp: Remove dependency on pv_irq_ops

2018-11-06T20:35:11Z

vSMP dependency on pv_irq_ops has been removed some years ago, but the code still deals with pv_irq_ops. In short, "cap & ctl & (1 << 4)" is always returning 0, so all PARAVIRT/PARAVIRT_XXL code related to that can be removed. However, the rest of the code depends on CONFIG_PCI, so fix it accordingly. Rename set_vsmp_pv_ops to set_vsmp_ctl as the original name does not make sense anymore.

x86/paravirt: Move the pv_irq_ops under the PARAVIRT_XXL umbrella

2018-09-03T14:50:36Z

All of the paravirt ops defined in pv_irq_ops are for Xen PV guests or VSMP only. Define them only if CONFIG_PARAVIRT_XXL is set.

x86/paravirt: Use a single ops structure

2018-09-03T14:50:35Z

Instead of using six globally visible paravirt ops structures combine them in a single structure, keeping the original structures as sub-structures. This avoids the need to assemble struct paravirt_patch_template at runtime on the stack each time apply_paravirt() is being called (i.e. when loading a module).

x86: replace __init_or_module with __init in non-modular vsmp_64.c

2015-06-16T18:12:41Z

The __init_or_module is from commit 05e12e1c4c09cd35ac9f4e6af1e ("x86: fix 27-rc crash on vsmp due to paravirt during module load"). But as of commit 70511134f61bd6e5eed19f767381f9fb3e762d49 ("Revert "x86: don't compile vsmp_64 for 32bit") this file became obj-y and hence is now only for built-in. That makes any "_or_module" support no longer necessary. We need to distinguish between the two in order to do some header reorganization between init.h and module.h and we don't want to be including module.h in non-modular code.

x86/vsmp: Fix irq routing

2014-04-28T07:27:34Z

Correct IRQ routing in case a vSMP box is detected but the Interrupt Routing Comply (IRC) value is set to "comply", which leads to incorrect IRQ routing. Before the patch: When a vSMP box was detected and IRC was set to "comply", users (and the kernel) couldn't effectively set the destination of the IRQs. This is because the hook inside vsmp_64.c always setup all CPUs as the IRQ destination using cpumask_setall() as the return value for IRQ allocation mask. Later, this "overrided" mask caused the kernel to set the IRQ destination to the lowest online CPU in the mask (CPU0 usually). After the patch: When the IRC is set to "comply", users (and the kernel) can control the destination of the IRQs as we will not be changing the default "apic->vector_allocation_domain".
