Please patch Mini-OS so that it uses stddef.h to define size_t and NULL. This problem fixes errors that occur when linking Mini-OS with ANSI standard code that uses stddef.h.

Hello, as some might have read in my previous postings, I have a Mini-OS dom0 that constructs a Mini-OS domU on x86 xen-3.0.4-testing. As the memory layout my Dom0 builds does not guarantee, that pages the DomU Mini-OS tries to use as page tables are mapped to existing memory, I changed new_pt_frame in arch/x86/mm.c in the following way: The pt_pfn is mapped R/W, then it is zeroed by a

This patch series contains a set of patches making minios rather easier to use, from an application development point of view. Overview of patches: 1 Command line argument parsing support, from Xen. 2 Weak console handler function. 3 Build system tweaks for application directories. 4 Trailing whitespace cleanup. (because it is very messy) Patch 4 is likely to be more controversial than

2 questions on the code of mini-os (the one in XEN 3.0.3): 1. In xen-3.0.3/extras/mini-os/mm.c:52 is a declaration of stack extern char *stack; but in file xen-3.0.3/extras/mini-os/arch/x86/setup.c:48, there is also a decl of stack: char stack[8192]; If one dereferences the variable stack, which is apparently not the case yet, it gives surely a segfault! 2.

samuel, I have a try with HVM stubdomain on r17062, but failed to make on 32b platform. Attached patch can fix it, but don''t know if okay. After installation, I failed to start stubdom. So I created it manually and got following debug mesg(both HVMdomain and stubdom are created) Can you give some lights on following questions: 1. I use default vnclisten. Does it matter? 2. Seems qemu

Hi, Let me start a new thread for this. I contacted the Grub people, and they seem more interested in creating a native Xen port of Grub than piggybacking the Mini-OS environment usin kexec as I tried. But they need some documentation on the Xen "firmware" to assess the task at least. What could be given to them apart from hvc_xen.c and xen-blkfront.c in the Linux sources?

I sent this patch directly to Gregor, and neglected to CC this list. Sorry about that. I''d like to make it so that there is no need to modify any Mini-OS source files when extending it with an application. All that is required is a change to Makefile, and a small change to kernel.c, printf.c, and string.c. I have enclosed the patch. With this patch, one could write an application in a

From: Ben Cressey <bcressey@amazon.com> The commit "minios: refactor xenbus state machine" caused "/state" to be appended to the local value of nodename. Previously the nodename variable pointed to dev->nodename. The xenbus_rm() calls were not updated to reflect this change, and refer to paths that do not exist. For example, shutdown_blkfront() for vbd 2049 would

For a while I''ve been intending to provide a better environment for PV baremetal guests. The current arrangements, based on newlib, take quite a bit of porting for many programs. My plan is to take the FreeBSD libc, and write a set of functions implementing the "system calls" in terms of facilities provided by the Xen PV environment, frontend drivers, etc. As part of this I

Hi Ian, There have been a lot of interest on gfx passthru recently. This patch enables ATI VBIOS in passthru mode. The guest VM system BIOS (including Windows boot logo) can now show in passthru screen. We have tested with various Windows and Linux guest VMs. Please help review it. We are also looking forward to comments and suggestions from Xen community users. Signed-off-by: Wei Huang

Legacy (non-pvops) gntdev drivers may require this operation to be performed when the number of grants intended to be used simultaneously exceeds a certain driver specific default limit, and qemu''s qdisk driver is an example of needing to do so.
