Loop in more Nuvoton folks. -----Original Message----- From: Yubin Zou <[email protected]> Sent: Wednesday, September 10, 2025 6:11 AM To: [email protected] Cc: Paolo Bonzini <[email protected]>; CS20 KFTing <[email protected]>; Hao Wu <[email protected]>; [email protected]; Peter Maydell <[email protected]>; Yubin Zou <[email protected]>; Titus Rwantare <[email protected]> Subject: [PATCH 0/7] Introduce PCIE Root Complex on Nuvoton npcm8xx and npcm7xx
CAUTION - External Email: Do not click links or open attachments unless you acknowledge the sender and content. Improvement to QEMU: These changes enhance QEMU by adding emulation support for a new piece of hardware, the Nuvoton PCIe root complex, which is prevalent in both NPCM7xx and NPCM8XX Board SoCs. Impact (Before/After): - Before: QEMU lacked a specific model for the Nuvoton PCIe host. Emulating platforms using this SoC meant PCIe capabilities were either missing or inaccurate. - After: QEMU can now model the fundamental aspects of the PCIe host controller. Virtual PCIe devices can be attached to emulated NPCM7xx and NPCM8xx machines, and the guest OS can interact with them through a more faithful representation of the on-chip PCIe hardware.
