Re: [RFC/RFT,v7] cpuidle: New timer events oriented governor for tickless systems

From: Chen Hu Hi Rafael, I run several popular Android performance benchmarks on teov7, using kernel 4.19.0 as my baseline because I happen to work on it. To backport teov7 to kernel 4.19.0, I also backport patch 5f26bdc: "cpuidle: menu: Fix wakeup statistics updates for polling

[PATCH] serial: 8250_dw: always set baud rate in dw8250_set_termios

esume_port ... So the baud rate is not restored after S3 and breaks the apps who use UART, for example, console and bluetooth etc. We address this issue by setting the baud rate irrespective of arg "old", just like the drivers for other 8250 IPs. This is tested with Intel Broxton platform. Si

Re: [PATCH] serial: core: stop passing NULL in uart_resume_port

Hi Andy, Thanks the feedback. Is it better to modify the DesignWare 8250 driver directly? Or do you think is this really an issue? Thanks Chen Hu
