Extending SeaBIOS for additional USB-HID devices
by Fox, Ethan 26 Sep '24

26 Sep '24

Hello! I am a university student and I am interested in extending SeaBIOS for a project which involves requiring connecting a USB SoloKey to your computer during the boot process. Implementing this in SeaBIOS seems promising since it looks like SeaBIOS has code written to interface with USB-HID keyboard and mice. I believe that SoloKey also follows this USB-HID spec. Is it feasible to extend the USB-HID code to also interact with SoloKey, or am I going to run into some road blocks? Any advice is welcome. Thanks, Ethan Fox

[PATCH 0/2] pci: skip pci resource allocation if instructed by platform
by Abhimanyu Saini 18 Sep '24

18 Sep '24

A hypervisor may want to perform PCI resource allocation (bus numbers, io and mmio ranges) and program the resulting values into the devices itself rather than delegate this to the firmware. Introduce a new flag in fw_cfg, "etc/pci-noalloc", to instruct the firmware to skip the resource allocation phase and use whatever is already programmed in the devices.

[PATCH] esp-scsi: indicate acceptance of MESSAGE IN phase data
by Mark Cave-Ayland 04 Sep '24

04 Sep '24

When the target has sent its MESSAGE IN phase data to the initiator, it waits for the initiator to release the ACK signal before disconnecting from the bus. Send a MSG_ACC command to the ESP so that the initiator releases the ACK signal to allow the target to disconnect, and also return the ASC back to the disconnected state.
