Hi folks, I'm working on an issue of HyperV synthetic frame buffer driver, which seems to have a conflict with the generic vga driver (not the vesa driver). I hope to read and trace into the source code for the generic vga driver... Can anyone point me to the source code file for the generic vga driver in the kernel tree? Thanks, - Haiyang

Everything lives in ./drivers/video/. The drivers you're probably interested in are "vesafb.c" or "vga16fb.c". There is also the "vgacon" driver in ./drivers/video/console/vgacon.c. I am not sure which one you are talking about. You might also want to have a look at the x86 sysfb infrastructure which isn't merged, yet: http://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/log/?h=x86/fb It provides proper platform-devices so drivers no longer conflict on the vga/vesa/efi.. framebuffer resources. It's x86 only as all the relevant drivers only work on x86. If you give some more information on what you are trying to do, I can point you to the relevant resources. My guess is that you want to have a look at remove_conflicting_framebuffers() in ./drivers/video/fbmem.c. Regards David
