[PATCH 2/2] hw/usb-hid: Don't abort if setting key repeat rate fails
by Matt DeVillier 06 Mar '20

Since the USB stack doesn't handle stalled pipes, don't abort keyboard setup if the set_idle command fails, since it's a non-critical feature. Instead, log a warning.

[PATCH v3] hw/usb-hid: handle devices with illegal max packet size
by Matt DeVillier 06 Mar '20

06 Mar '20

Some USB keyboards report 9 or 10-byte max packet sizes, instead of the 8-byte max specified by the USB HID spec. Handle this by increasing the size of the keyevent struct to 10 bytes, and using the key array size of the usbkeyinfo struct as loop bounds rather than that of the keyevent struct (since the former will always be smaller, and within spec).

onboard NIC eno1
by Gisbert Haas 27 Jan '20

27 Jan '20

Hallo All, I have a proprietary application running on Debian9 with hardcoded NIC "eno1". If I would like to use virtualization I need to have the NIC show up as onboard NIC so systemd will name it eno1. I dont have access to the OS Debian9 to change anything. is there a way to have the Bios report the NIC as onboad eno1? Thanks a lot

[PATCH 0/1] build: increase .version priority over git
by Alexey Kirillov 22 Jan '20

22 Jan '20

Now there is no convenient way to set the version number in the required format if we build SeaBIOS from the repository. It is proposed first of all to get the version number from the .version file if it exists, if it is absent, from git. This approach will allow you to safely specify the version manually and will not affect existing builds.

[PATCH v3 0/2] Initialize only bootable virtio-blk/virtio-blk
by Alexey Kirillov 14 Jan '20

14 Jan '20

This patch aimed to avoid problem with uninitialized virtio-blk and virtio-scsi boot devices. Currently, 12 KiB of memory is allocated for each virtio-blk/scsi, so no more than about 10 devices can be initialized. If the device is not initialized, we cannot boot from it. So, if we have more than 10 devices, we can't boot from any of the following (11, 12, etc.). We can initialize only bootable devices, i.e. listed in boot order list, that this patch does.
