Hi all,
Changes since 20200706:
on i386:
when CONFIG_ACPI is not set/enabled:
../drivers/scsi/lpfc/lpfc_init.c:1265:15: error: implicit declaration of
function 'get_cpu_idle_time'; did you mean 'get_cpu_device'?
[-Werror=implicit-function-declaration]
The cpufreq people want justification for using
get_cpu_idle_time(). Please see
https://lore.kernel.org/linux-scsi/20200707030943.xkocccy6qy2c3hrx@vireshk-i7/
The driver is using cpu utilization in order to choose between softirq
or work queues in handling an interrupt. Less-utilized, softirq is used.
higher utilized, work queue is used. The utilization is checked
periodically via a heartbeat.
