Hello,
I am using Seabios for qemu startup, and interested in the debugging by
GDB to see how the bios works.
Currently, I do it as https://www.seabios.org/Debugging said but met
some problems so that couldn't move on. :(
Could someone give some pointers on what I missed or have to do to

Hi all,
I re-send the serial because of wrong numbering last time.
Sorry for troubling.
Thanks!

I copy your comments of this patch several days ago here,

Hi,
I think PCI_DEVICE_ID_REDHAT_PCIE_BRIDGE shoud be added too, in case we put

Yes, please.
Thanks for comments. Sure, can be added simply. While this bridge
doesn't have resource reserve capability

Hi,
Recently, we tried some hotplug issues. The case is: when hotplug a
device (e.g. iGPU) onto pci-bridge after guest booting up, guest reports
"BAR 2: no space for [mem size 0x4000 64bit pref]" etc.
Seabios checks all the devices under the pci-bridge when qemu launching
the guest, and
Yep, thanks for the advice.
But hotplugging on pci-bridge is the actual use case
request so we would better solve and fix this.
