similar to: [PATCH] minios: new version netfront driver

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

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

hi, it would be extremely useful for me if someone with knowledge of how the current tools and drivers use Xenstore would be kind enough to update the Wiki with current information. I have been spending quite a lot of time trying to get my domU connected to a block device in dom0 using a home-brewed domain creation tool, and I am still at the ''Timeout connecting to device!''

I am pleased to announce the release of GUK (Project Guest VM Microkernel), which is an enhanced version of Mini-OS that underpins the Guest VM virtual machine.

Although GUK was developed specifically for Guest VM, it can be used stand-alone in a similar way to Mini-OS. The main

I am getting the following error when I try to bring up Mini-OS on x86_64 Xen (unstable: 9994). It is dying in xc_linux_build() causing xend to fault and restart. Any clue why this happening? Has something changed in the builder that Mini-OS needs to be aware of? PS: I tried reverting changeset 9993 (Allow linking of mini-os with application-specific object code), but still got the same error

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

This patch adds a new feature called feature-split-event-channels for netfront, enabling it to handle TX and RX events separately. If netback does not support this feature, it falls back to use single event channel.

hi, it seems I no longer need to pin l1 pages when running with writable page tables in xen-unstable -- e.g. I can now pin a l2 table without having pinned its l1 descendants first, without Xen complaining.
