[v3] virtio-spi: Sync Linux headers and add vhost-user-spi device support

[PATCH v3 0/2] virtio-spi: Sync Linux headers and add vhost-user-spi device support

Posted by Haixu Cui 1 month, 3 weeks ago

This patch series introduces vhost-user-spi device support to QEMU
and synchronizes relevant standard headers from upstream Linux.

The series consists of the following changes:
1. Synchronize virtio_spi.h from Linux kernel (v6.18-rc3) using
   scripts/update-linux-headers.sh.
2. Implement vhost-user-spi and vhost-user-spi-pci devices in QEMU,
   enabling virtio-based SPI communication via the vhost-user protocol.

The new device implementation follows the virtio-spi specification and
leverages the upstream Linux virtio-spi driver. This enables QEMU to emulate
SPI devices using the vhost-user protocol, facilitating integration with external
SPI daemons and improving virtualization support for SPI peripherals.

Changes between V3 and V2:
- Removed the patch to update virtio_ids.h since it is already updated
Changes between V2 and V1:
- Added vhost-user-spi entry in docs/system/devices/virtio/vhost-user.rst

Hi QEMU developers,

I’m following up on my patch posted on 12/16/2025, and haven’t received 
any review yet.

Could you please take a look when you get a chance? I’m happy to update 
it based on feedback.

Thanks,
Haixu
