Description Vincent Milum Jr 2020-10-12 22:48:58 UTC
Now that there is an ARM64 version of VMware, I've added several of the drivers from AMD64 GENERIC over to ARM64 GENERIC. These drivers all work out of the box, unmodified, under VMware ESXi ARM Fling.

Adding the following drivers for VMware virtual machines

vmx: vmxnet3 virtual network card
pvscsi: paravirtual scsi
uhci: USB 2.0 controller
ums: USB mouse

Comment 1 Conrad Meyer freebsd_committer 2020-10-12 23:47:36 UTC
LGTM except for files.arm64 — those files should be moved into generic conf/files, assuming they're in files.x86 today.
Comment 2 Vincent Milum Jr 2020-10-13 03:03:33 UTC
Right, I copied them from files.amd64 into files.arm64

If these should be in the main files (generic) instead of the arch specific files, I'll leave that up to the experts.

As of right now, VMware only supports i386, amd64, and arm64. There is no support for arm (32-bit), or the other platforms like mips, powerpc, or riscv.

  move vmware pv drivers to sys/conf/files

  VMware now has arm64 support; move these to MI files in advance of
  building them on arm64.

Is there no need for vmci on arm64?

"Is there no need for vmci on arm64?"

Me personally, I've never used an application that uses is on x86. Others might see it as useful? But when I was trying to compile it, I found a bunch of x86 ASM macros that I didn't feel like digging into at the time, so I've not gotten it working at all yet.
