[SeaBIOS] [PATCH v2 0/2] Fix reset issue with QEMU -machine q35

Posted by Volker Rümelin 2 years, 1 month ago

This reset issue was reported on the QEMU issue tracker at
https://gitlab.com/qemu-project/qemu/-/issues/766

A reset with QEMU -machine q35 -accel tcg leads to a reset loop
and with -machine q35 -accel kvm the reset only works because
KVM ignores the read-only semantics of the C-F segments.

Details about the issue are in "reset: force standard PCI
configuration access".

v2:
The commit message of patch "reset: force standard PCI config-
uration access" now uses the correct PCI configuration register
name PCIEXBAR.

Volker Rümelin (2):
   pci: refactor the pci_config_*() functions
   reset: force standard PCI configuration access
