RE: Update virtio network driver

so works well when we use RTEMS_COMPILER_MEMORY_BARRIER() because the driver almost works well without any barrier, too. -Original Message- From: ged...@gwmail.gwu.edu [mailto:ged...@gwmail.gwu.edu] On Behalf Of Gedare Bloom Sent: Friday, November 11, 2016 3:27 AM To: Jinhyun Cc: devel@

Update virtio network driver

Hi, all! We removed our RTEMS-virtio driver's dependencies on architecture. We used built-in function of gcc, __sync_synchronize(). This function generates proper memory barrier for target architecture on compile time. In addition, we replaced pcib_conf_read/write functions to pci_read/write_conf

A virtio front-end driver for RTEMS

Hi,  I am a graduate student of System Software Lab at Konkuk University (http://sslab.konkuk.ac.kr). We are implementing a virtio front-end network driver for RTEMS and have  published some preliminary results in ACM SIGBED Review (http://sigbed.seas.  upenn.edu/archives/2016-01/EWiLi15_5.pdf).
