Hi all. I am trying to debug a kernel that I built, and I hope I could see some debug info printing out via XENPRINTF. I use it in the source code of kernel like: XENPRINTF("nr_pages: %ld shared_info: 0x%lx flags: 0x%lx pt_base: 0x%lx " "mod_start: 0x%lx mod_len: 0x%lx\n", xen_start_info->nr_pages, xen_start_info->shared_info, xen_start_info->flags, xen_start_info->pt_base, xen_start_info->mod_start, xen_start_info->mod_len); But it doesn''t print anything out when start this kernel as domU.

Hi, I‘m trying to install vTPM based on Xen-4.2.2, linux-kernel 3.9.1 (Dom0) and TPM emulator. However, I cannot find the TPM backed driver in this version of Dom0 linux kernel. There is no CONFIG_XEN_TPMDEV_BACKEND in the kernel config file. The config file for Dom0 is attached. Maybe it provides some useful information. So, how to install a Xen TPM backend driver in the Dom0 linux-kernel.

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
