Subject: [PATCH 0/3] x86: Fixes for not-quite-XSA in pci_conf_write_intercept()
Date: Tue, 8 Sep 2026 22:57:18 +0100 [thread overview]
Message-ID: <20260908215721.3346842-1-andrew.cooper3@citrix.com> (raw)
Plumb pci_sbdf_t up and down the callchain to simplify parameter passing and
make it harder to forget the segment.
Andrew Cooper (3):
x86/pv: Convert struct mmio_ro_emulate_ctxt to use pci_sbdf_t
x86/pci: Convert pci_mmcfg_{read,write}() to use pci_sbdf_t
x86/pci: Update pci_conf_write_intercept() to use pci_sbdf_t
