Limiting to 4096, assuming this is used for virtual io block device. The
default maximum (256kB) would result in overflowing of bounce buffers
and stalling of IO (max_segments of 254 for block device and max
bounce size of 256kB could result in block layer submitting a huge IO
request that can never be finished successfully). With 4096, we have
the max size of request set to 254*4096, which is a reasonable space
to set aside per block device.

In some cases, its possible that most of a VM's memory is not
accessible to virtual io backend drivers that run in the context of a
separate VM. A hypervisor could pre-share some limited memory between
both the VMs. Use such pre-arranged shared memory to allow data
exchange between front-end and back-end drivers. DMA ops are added to
virtual io (mmio) devices, which bounces buffers to and from the
pre-shared region.

If LMH (Limits Management Hardware) is available, when a policy is
disabled by unplugging the last online CPU of policy->cpus, the LMH
irq is left enabled.
When the policy is re-enabled with any of the CPU in policy->cpus
being plugged in, qcom_cpufreq_ready() re-enables the irq. This
triggers the following warning:
[ 379.160106] Unbalanced enable for IRQ 154

When cpu is hotplugged out, cpu stack is torn down and lmh mitigation
also stops. Hence on lmh exit remove thermal pressure.
This will ensure that scheduler requests higher frequency when
cpu is back online again, since it's likely the CPU has cooled down
in the meantime. And if it hasn't, then lmh IRQ will fire again and
we'll reapply pressure.

If LMH (Limits Management Hardware) is available, when a policy is

qcom_cpufreq_hw_cpu_offline() sets cancel_throttle=true.
cancel_throttle is not reset when the policy is re-enabled with any
of the CPU in policy->cpus being plugged in. So reset it.
This patch also adds an early exit check.

If cpu is hotplugged then policy->cpus is cleared in cpufreq_offline
which will results in device being NULL on last CPU hotplugged out.
Also since cpu is hotplugged out, polling callback can safely be

Currently, when lmh interrupt fires we notify the scheduler about
thermal pressure. The scheduler reduces the capacity of the cpu(s)
for which the interrupt fired, while we requeue our deferrable work.
This leads to an interesting deadlock, since the cpu is running with
reduced capacity, the scheduler does not put any task on it,
extending the idle time and causing it to remain at reduced capacity -
leading to severe underutilization of the cpu(s).
Switch to using delayed work instead of deferrable work. This will cause
us to exit idle until the thermal condition is recovered.
