hyperv/vmbus: avoid crash, panic if vbe fb info is missing

2020-12-10T13:11:52Z

Do not assume that VBE framebuffer metadata can be used. Like with the EFI fb metadata, it may be null, so we should take care not to dereference the null vbefb pointer. This avoids a panic when booting -CURRENT on a gen1 VM in Azure. Approved by: tsoome Sponsored by: Miles AS Differential Revision: https://reviews.freebsd.org/D27533

Add VT driver for VBE framebuffer device

2020-11-30T08:22:40Z

Implement vt_vbefb to support Vesa Bios Extensions (VBE) framebuffer with VT. vt_vbefb is built based on vt_efifb and is assuming similar data for initialization, use MODINFOMD_VBE_FB to identify the structure vbe_fb in kernel metadata. struct vbe_fb, is populated by boot loader, and is passed to kernel via metadata payload.

Prevent framebuffer mmio space from being allocated to other devices on HyperV.

2020-07-30T07:26:11Z

On Gen2 VMs, Hyper-V provides mmio space for framebuffer. This mmio address range is not useable for other PCI devices. Currently only efifb driver is using this range without reserving it from system. Therefore, vmbus driver reserves it before any other PCI device drivers start to request mmio addresses.

Introduce a per-page flag, VPO_KMEM_EXEC, to mark physical pages that are mapped in kmem with execute permissions. Use this flag to determine which arena the kmem virtual addresses are returned to. Eliminate UMA_SLAB_KRWX. The introduction of VPO_KMEM_EXEC makes it redundant. Update the nearby comment for UMA_SLAB_KERNEL.
