drivers/video: add Hyper-V Synthetic Video Frame Buffer Driver This is the driver for the Hyper-V Synthetic Video, which supports screen resolution up to Full HD 1920x1080 on Windows Server 2012 host, and 1600x1200 on Windows Server 2008 R2 or earlier. It also solves the double mouse cursor issue of the emulated video mode. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Reviewed-by: K. Y.

hyperv-fb: add support for generation 2 virtual machines. UEFI-based generation 2 virtual machines support vmbus devices only. There is no pci bus. Thus they use a different mechanism for the graphics framebuffer: Instead of using the vga pci bar a chunk of memory muct be allocated from the hyperv mmio region declared using APCI.

video: hyperv: hyperv_fb: refresh the VM screen by force on VM panic Currently the VSC has no chance to notify the VSP of the dirty rectangle on VM panic because the notification work is done in a workqueue, and in panic() the kernel typically ends up in an infinite loop, and a typical kernel config has CONFIG_PREEMPT_VOLUNTARY=y and CONFIG_PREEMPT is not set, so a context switch can't happen in panic() and the workqueue won't have a chance to run. As a result, the VM Connection window can't refresh until it's closed and we re-connect to the VM. We can register a handler on panic_notifier_list: the handler can notify the VSC and switch the framebuffer driver to a "synchronous mode", meaning the VSC flushes any future framebuffer change to the VSP immediately. v2: removed the MS-TFS line in the commit message v3: remove some 'unlikely' markings v4: avoid global variables as Tomi Valkeinen suggested Cc: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: Dexuan Cui <decui@microsoft.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

hyperv-fb: add support for generation 2 virtual machines. UEFI-based generation 2 virtual machines support vmbus devices only. There is no pci bus. Thus they use a different mechanism for the graphics framebuffer: Instead of using the vga pci bar a chunk of memory muct be allocated from the hyperv mmio region declared using APCI.

video: hyperv: hyperv_fb: refresh the VM screen by force on VM panic Currently the VSC has no chance to notify the VSP of the dirty rectangle on VM panic because the notification work is done in a workqueue, and in panic() the kernel typically ends up in an infinite loop, and a typical kernel config has CONFIG_PREEMPT_VOLUNTARY=y and CONFIG_PREEMPT is not set, so a context switch can't happen in panic() and the workqueue won't have a chance to run. As a result, the VM Connection window can't refresh until it's closed and we re-connect to the VM. We can register a handler on panic_notifier_list: the handler can notify the VSC and switch the framebuffer driver to a "synchronous mode", meaning the VSC flushes any future framebuffer change to the VSP immediately. v2: removed the MS-TFS line in the commit message v3: remove some 'unlikely' markings v4: avoid global variables as Tomi Valkeinen suggested Cc: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: Dexuan Cui <decui@microsoft.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

hyperv-fb: add pci stub This patch adds a pci stub driver to hyper-fb. The hyperv framebuffer driver will bind to the pci device then, so linux kernel and userspace know there is a proper kernel driver for the device active. lspci shows this for example: [root@dhcp231 ~]# lspci -vs8 00:08.0 VGA compatible controller: Microsoft Corporation Hyper-V virtual VGA (prog-if 00 [VGA controller]) Flags: bus master, fast devsel, latency 0, IRQ 11 Memory at f8000000 (32-bit, non-prefetchable) [size=64M] Expansion ROM at <unassigned> [disabled] Kernel driver in use: hyperv_fb Another effect is that the xorg vesa driver will not attach to the device and thus the Xorg server will automatically use the fbdev driver instead.

drivers/video: add Hyper-V Synthetic Video Frame Buffer Driver This is the driver for the Hyper-V Synthetic Video, which supports screen resolution up to Full HD 1920x1080 on Windows Server 2012 host, and 1600x1200 on Windows Server 2008 R2 or earlier. It also solves the double mouse cursor issue of the emulated video mode. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Reviewed-by: K. Y.
