wonkoIf I do decide to try this PCIe passthrough thing is there a known to work usb serial dongle that reliably works as a console port?
-
toastersonwonko: why would you need a phisical serial port then you not even forward the USB?
-
wonkoI need a console for the NUC itself if I'm going to pass the GPU through
-
toastersonah, I see.
-
toastersonTHere are a couple in the OpenIndiana HCL, those will work for smartos as well docs.openindiana.org/community-hcl/components/#serial-controllers
-
jclulowwonko: I'm not sure the USB console stuff works at all to be honest
-
wonkojclulow: it would surprise me greatly if it did to be honest.
-
jclulowI mean it's theoretically possible for it to work for some purposes
-
jclulowI just don't think it does right now haha
-
jclulowYou would not be able to interact with the bootloader for example, or at least early kmdb
-
toastersonConsole ttya?
-
jclulowBut with fixes it would likely work for the actual system ttymon
-
jclulowWith temporary boot environment activation available now though I suspect the cases where you'd need to interact with the boot loader to fix boot are fewer
-
toastersonisn't serial console ttya?
-
toastersonshouldn't it work the same as bhyve
-
toastersonor libvirt?
-
jclulowttya is, on x86 systems, specifically the PC-compatible COM1
-
jclulowIt's a specific kind of UART chip that is attached to specific I/O ports on the CPU (effectively)
-
jclulowa USB serial console is vastly different, and requires a lot more machinery (e.g., a USB stack) to wokr
-
jclulow*work
-
jclulowThey're definitely not equivalent
-
rennjspi uart usb pick something....sparc had nice ttyA ttyB
-
rennjhandshaking, device detection, auto speed negotiation yeah usb going to be more complicated
