C++ (Cpp) vmm_cpumask_first Examples

Example #1

File: gic.c Project: bandwidthcrunch/xvisor

static int gic_set_affinity(struct vmm_host_irq *irq, 
			    const struct vmm_cpumask *mask_val,
			    bool force)
{
	virtual_addr_t reg;
	u32 shift = (irq->num % 4) * 8;
	u32 cpu = vmm_cpumask_first(mask_val);
	u32 val, mask, bit;

	if (cpu >= 8)
		return VMM_EINVALID;

	reg = gic_dist_base(irq) + GIC_DIST_TARGET + (gic_irq(irq) & ~3);
	mask = 0xff << shift;
	bit = 1 << (cpu + shift);

	val = gic_read(reg) & ~mask;
	gic_write(val | bit, reg);

	return 0;
}

Example #2

File: irq-gic.c Project: IRT-SystemX/xvisor-next

static int gic_set_affinity(struct vmm_host_irq *d,
			    const struct vmm_cpumask *mask_val,
			    bool force)

	u32 shift = (d->hwirq % 4) * 8;
	u32 cpu = vmm_cpumask_first(mask_val);
	u32 val, mask, bit;
	struct gic_chip_data *gic = vmm_host_irq_get_chip_data(d);

	if (cpu >= 8)
		return VMM_EINVALID;

	reg = gic->dist_base + GICD_TARGET + (d->hwirq & ~3);
	mask = 0xff << shift;
	bit = 1 << (cpu + shift);

	val = gic_read(reg) & ~mask;
	gic_write(val | bit, reg);

	return 0;
