* pv-on-hvm: Signal crash to Xen tools when HVM guest panics.Keir Fraser2008-02-133-0/+59
| | | | | | | | | | | | | | | | | Attached patch adds a function to automatically dump core file when guest linux on HVM domain panics, in the same way as PV domain. I tested this patch with kernel 2.6.9 and 2.6.18 on both of x86 and ia64 (to buid for ia64, some patches in the ia64 tree are needed) by the following steps, and confirmed it works well: 1. Build xen-platform-pci.ko. 2. In /etc/xen/xend-config.sxp, set (enable-dump yes). 3. On guest linux, execute insmod: # insmod xen-platform-pci.ko 4. When guest linux panics, a core file is dumped.

* [BUILD] Disable LOCALVERSION_AUTO in upstream Linux builds.Keir Fraser2008-02-121-0/+1
| | | | | | | | | | If this option is enabled then the Xen mercurial version ID gets tacked onto the kernel version (e.g. 2.6.24-git22-hg2593b69b183b) which is unlikely to be useful or desirable. All the trees which we build using this method already have uniquely identifying versions (e.g. 2.6.24-git22 or 2.6.24-mm1). Signed-off-by: Ian Campbell <ian.campbell@citrix.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Move PAGE_SIZE and STACK_SIZE into __PAGE_SIZE and __STACK_SIZE in arch_limits.h so as to permit getting them from there without pulling all the internal Mini-OS defines. - Setup a xen-elf cross-compilation environment in stubdom/cross-root - Add a POSIX layer on top of Mini-OS by linking against the newlib C library and lwIP, and implementing the Unixish part in mini-os/lib/sys.c - Cross-compile zlib and libpci too. - Add an xs.h-compatible layer on top of Mini-OS' xenbus. - Cross-compile libxc with an additional xc_minios.c and a few things disabled. - Cross-compile ioemu with an additional block-vbd, but without sound, tpm and other details. A few hacks are needed: - Align ide and scsi buffers at least on sector size to permit direct transmission to the block backend. While we are at it, just page-align it to possibly save a segment. Also, limit the scsi buffer size because of limitations of the block paravirtualization protocol. - Allocate big tables dynamically rather that letting them go to bss: when Mini-OS gets installed in memory, bss is not lazily allocated, and doing so during Mini-OS is unnecessarily trick while we can simply use malloc. - Had to change the Mini-OS compilation somehow, so as to export Mini-OS compilation flags to the Makefiles of libxc and ioemu.

* ioemu: Dynamic VNC colour depth.Keir Fraser2008-02-117-80/+207
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The qemu vnc server changes its internal colour depth based on the client request. This way just one colour conversion is done: the one in vga_template.h, from the guest colour depth and the vnc server internal colour depth. This patch is meant to remove this colour conversion to improve performances. It accomplishes the goal making the qemu internal colour depth always the same as the guest colour depth. The basic idea is that the vnc client is the one that should do the colour conversion, if necessary. In general it should accept the pixel format suggested by the server during the initial negotiation. This behaviour can be set in most vnc clients (vncviewer included). If the guest changes colour depth, the qemu vnc server changes colour depth too and notifies the client. The problem is that the vnc protocol doesn't provide a message from the server to the client to ask for a colour depth change. So what I am doing is either: 1) quietly starting to do the conversion on vnc server (not gaining any performance here); 2) closing the vnc connection with the client, so the client can reconnect and choose the new pixel format. By default I am doing 1), however the second choice can be enabled passing the -vnc-switch-bpp command line option. In order to do the colour conversion on the vnc server I had to improve the colour conversion code already in place because it only supported conversions from 32 bpp. The patch adds colour conversion code that support conversions from any resolution to any resolution. A last note: to get most out of this patch it is best to set Windows to 16 bit colour depth, because the 24 bit mode is 24 bit depth and 24 bpp, meaning no alpha channel. The vnc protocol doesn't support 24 bpp, only 32 bpp, so this conversion is unavoidable.

* ioemu: avoid name clashes due to LIST_* macrosKeir Fraser2008-02-075-48/+48
| | | | | | | | | | | | | | | | | | | | | Here is what I wrote in my submission to qemu upstream: qemu's audio subdirectory contains a copy of BSD's sys-queue.h, which defines a bunch of LIST_ macros. This makes it difficult to build a program made partly out of qemu and partly out of the Linux kernel[1], since Linux has a different set of LIST_ macros. It might also cause trouble when mixing with BSD-derived code. Under the circumstances it's probably best to rename the versions in qemu. The attached patch does this. [1] You might well ask why anyone would want to do this. In Xen we are moving our emulation of IO devices from processes which run on the host into a dedicated VM (one per actual VM) which we call a `stub domain'. This dedicated VM runs a very cut-down `operating system' which uses some code from Linux. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
