This is a pair of Xen para-virtual frontend device drivers: drivers/video/xen-fbfront.c provides a framebuffer, and drivers/input/xen-kbdfront provides keyboard and mouse. The backends run in dom0 user space. I started with the Xen version at http://xenbits.xensource.com/linux-2.6.18-xen.hg?rev/ca05cf1a9bdc Differences to that Xen version, for those who care: * Rewritten on top of fb deferred I/O * IRQ handler names visible in /proc and /sys match the driver names. * Use framebuffer helper functions appropriate for framebuffer in system RAM. * write() refreshes the framebuffer properly. * off-by-one height of some screen refreshs fixed. * Crash when register_framebuffer() fails fixed. * Test for empty ring in input_handler() fixed. * Deadlock in xen-kbdfront resume fixed. * General clean up. I have a step-by-step patch series from that Xen version to my version, if anybody is interested. Might be useful for reviewers familiar with the Xen version. The patch consists of two parts: 1. fbdev: Make deferred I/O work as advertized I need fb deferred I/O, but is utterly broken. A fix has been floating around on linux-fbdev-devel as part of a larger patch, which as far as I know has not been merged anywhere, yet. This is just the fix. 2. xen pvfb: Para-virtual framebuffer, keyboard and pointer driver The actual drivers. - To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
