[Xen-devel] [PATCH v8 0/4] Fix PCI passthrough for HVM with stubdomain

Posted by Marek Marczykowski-Górecki 4 years, 7 months ago

This version is rebase libxl patches on staging. Changes to "libxl: attach PCI
device to qemu only after setting pciback/pcifront" are significant enough that
I've dropped Wei's ack.
Also, there is a new patch to fix regression introduced during async conversion.

Changes in v2:
 - new "xen/x86: Allow stubdom access to irq created for msi" patch
 - applied review comments from v1
Changes is v3:
 - apply suggestions by Roger
 - add PHYSDEVOP_msi_msix_set_enable
Changes in v4:
 - implement suggestions by Wei, Roger, Jan
 - plug new physdevop into XSM
Changes in v5:
 - rebase on master
 - rename to PHYSDEVOP_msi_control
 - move granting access to IRQ into create_irq
Changes in v6:
 - simplify granting IRQ access, record dm domid for cleanup
 - rename to PHYSDEVOP_interrupt_control
 - include INTx control in the hypercall
Changes in v7:
 - update "xen/x86: Allow stubdom access to irq created for msi"
 - drop "xen/x86: add PHYSDEVOP_interrupt_control"
 - drop "tools/libxc: add wrapper for PHYSDEVOP_interrupt_control"
Chages in v8:
 - drop applied "xen/x86: Allow stubdom access to irq created for msi"
 - new patch "libxl: fix cold plugged PCI device with stubdomain"
 - rebase libxl patches on staging
