Hi All,
Updating to CentOS 7.3 and using Linux drivers from the website we are seeing MSI Enable-
"
[CentOS7 ~]# lspci -d 10de:1b80 -nn -v | grep “MSI: En”
Capabilities: [68] MSI: Enable- Count=1/1 Maskable- 64bit+
Capabilities: [68] MSI: Enable- Count=1/1 Maskable- 64bit+
"
In CentOS 6+ everything works fine and we see:
[CentOS6 ~]# lspci -d 10de:1b80 -nn -v | grep “MSI: En”
Capabilities: [68] MSI: Enable+ Count=1/1 Maskable- 64bit+
Capabilities: [68] MSI: Enable+ Count=1/1 Maskable- 64bit+
Enabling persistent mode we Enable+ for MSI now works.
Maybe 7.3 compatibility is still too young?
