Hi, Joe,

 

After change vuart irq from 4 to 6, the SOS kernel config need enable CONFIG_SERIAL_8250_DETECT_IRQ, otherwise, the ttyS0 will work under polling mode and slowly…

Hi Geoffroy & list,

Any news on this?
On my side the issue is related to the uart being very slow. SystemD messages appears very slowly through the uart.
After bisecting a bunch of commit I eventually found it may be related to the commit 1c7d2f653ad380b5447bc50abc5e2cb4e24c32e2 linked to the issue https://github.com/projectacrn/acrn-hypervisor/issues/1476
If I change back COM1_IRQ to 4 in hypervisor/include/debug/vuart.h, boot time is back to normal.

Thanks,
Joe
