The Virtualbox SVGA card was derived out of the KVM VGA card, so there are quite a few similarities (I am deliberately being vague here as I am still in the process of discovering the features of both these cards completely). Having said that, the APIs and the data structures themselves have been modified to add new features (like displaying a custom bmp as the VGA bootup logo) and it has a custom vga bios as well. Also, it is better that it be its own separate device model, so that maintenance of the vbox code becomes easier later. Further, I am thinking on the lines of retaining the VIrtualbox SVGA card code as is, and write a small KVM abstraction layer, so that it will be easy to port the bug fixes into the vbox SVGA card later on. Any comments/suggestions welcome here. -Sriram ----- Original Message ----- From: Peter Maydell <peter.maydell@xxxxxxxxxx> To: Sriram Murthy <sriramsm@xxxxxxxxx> Cc: Stefan Hajnoczi <stefanha@xxxxxxxxx>; qemu list <qemu-devel@xxxxxxxxxx>; "kvm@xxxxxxxxxxxxxxx" <kvm@xxxxxxxxxxxxxxx> Sent: Monday, April 8, 2013 8:11 AM Subject: Re: [Qemu-devel] Virtualbox svga card in KVM On 6 April 2013 00:52, Sriram Murthy <sriramsm@xxxxxxxxx> wrote: > (actually, the virtualbox SVGA card is based off of the KVM VGA card) Is it possible to implement it as an extension to the VGA card device, or has it diverged incompatibly such that it has to be its own separate device model? thanks -- PMM -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
