This series adds a shortcut for network boot, similar to what is present on bare-metal machines. F11 will prioritize BCV/BEV entries for network devices over all the other items of the boot list.
After testing with a more recent QEMU I found that it deploys a BCV ROM that breaks network boot. So this series has two extra patches that track the PCI class for boot entries; this is then used to filter boot entries for network boot. A better choice of priorities for BCV and BEV is also implemented (patch 3).
After Peter Stuge's prod, I reorganized interactive_bootmenu to use a switch statement, and split the reindentation away in a separate patch.
Hi Paolo,
Can you give a high-level overview of why this functionality is needed? For QEMU users, wouldn't they just add "-boot net" to their command line?
Good question. :) This came in as a feature request from a RH customer, and it took a while to understand that this was the feature they wanted. My only guess is the user is someone else than the administrator, so they cannot control the QEMU command-line.
Okay. I guess hitting F12 and then selecting the network card was too complex. :-)
I'm not sure how much of this code is used by Coreboot, but I figured this would be somewhat useful on bare-metal systems too.
It's the same menu on coreboot. Indeed, having the ability to select a boot device is critical when working on real hardware.
Thanks. -Kevin
