similar to: [PATCH 0/2] xen pvfb: Para-virtual framebuffer, keyboard and pointer

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. Differences since last post: * Required patch fixing 32-on-64 xen-blkfront included. * Cleanup when xenkbd_probe() fails fixed. * Don't store event channel in device info. I started

This is an update to the Linux part of the Xen PVFB. Linux Xen PVFB 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. Their backends run in dom0 user space. Parts in this patch series: 1. Enable Xen console by default in domU 2. Pointer z-axis (mouse wheel) support 3. Module

From: Santosh Jodh <santosh.jodh at citrix.com> Add support for multi page ring for block devices. The number of pages is configurable for blkback via module parameter. blkback reports max-ring-page-order to blkfront via xenstore. blkfront reports its supported ring-page-order to blkback via xenstore. blkfront reports multi page ring references via ring-refNN in xenstore. The change allows

Without console= arguments on the kernel command line, the first console to register becomes enabled and the preferred console (the one behind /dev/console). This is tty (assuming CONFIG_VT_CONSOLE is enabled, which it commonly is). This is okay as long tty is a useful console. But unless we have the PV framebuffer, and it is enabled for this domain, tty0 in domU is merely a dummy. In that

Netback and netfront only use one event channel to do tx / rx notification. This may cause unnecessary wake-up of process routines. This patch adds a new feature called feautre-split-event-channel to netback, enabling it to handle Tx and Rx event separately. Netback will use tx_irq to notify guest for tx completion, rx_irq for rx notification. If frontend doesn''t support this feature,

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths
