◆ getPhysicalPage()

physical_uintptr_t VirtioGpu::GpuFramebuffer::getPhysicalPage ( size_t offset ) const

overridevirtual

Gets the physical page backing an offset in the framebuffer. This is used by direct framebuffer mappings such as /dev/fb. Providers backed only by a virtual buffer should retain the default failure.

Reimplemented from Framebuffer.
