- On x86 "vga=current" can now be used together with GrUB2's gfxpayload setting. Note that
|
||||
this requires use of "multiboot2" (and "module2") as the GrUB commands loading Xen.
|
||||
|
||||
### Added / support upgraded
|
||||
- IOMMU superpage support on x86, affecting PV guests as well as HVM/PVH ones
|
||||
when they don't share page tables with the CPU (HAP / EPT / NPT).
|
||||
|
||||
### Removed / support downgraded
|
||||
- dropped support for the (x86-only) "vesa-mtrr" and "vesa-remap" command line options
