flowtop: Fix hanging while waiting for collector
Fixed issue when flowtop hangs be cause of wrong using pthread cond lockiing, so the lock should be locked first by calling thread before call to pthread_cond_wait. Fixes: 451275470106 ("flowtop: Don't init screen until collector is ready") Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

th Windows, because the BIOS also neglects to provide the ACPI/CPPC table, that Windows requires to enable HWP, and so Windows runs in legacy P-state mode, where this setting has no effect. Linux' intel_pstate driver does not require ACPI/CPPC to enable HWP, and so it runs in HWP mode, exposing this incorrect BIOS configuration. There are several ways to address this problem. First, Linux can also run in legacy P-state mode on this system. As intel_pstate is how Linux enables HWP, booting with "intel_pstate=disable" will run in acpi-cpufreq/ondemand legacy p-state mode. Or second, the "performance" governor can be used with intel_pstate, which will modify HWP.EPP to 0. Or third, starting in 4.10, the /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference attribute in can be updated from "balance_power" to "performance". Or fourth, apply this patch, which fixes the erroneous setting of MSR_IA32_POWER_CTL BIT_EE on this model, allowing the default configuration to function as designed.
