Thanks for your ideas, Sean ! >The bug is not likely to be corrupted data in the decompressed output (that is just calling into a gzip routine or something). You shouldn't have to dump/printf->trace from memory during boot to see that data since the "real" kernel binary that is being decompressed into that memory region is probably already somewhere > in your build tree

With latest kernel (Linus tree as of 5.6 merge window), I get the following warning in the kernel 'dmesg': [ 5.746588] process '/bin/sh' started with executable stack This comes from commit https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/fs/exec.c?id=47a2ebb7f5053387f5753b524f4920b9b829f922 "execve: warn if process starts with executable

Hi, I hope I''m right here. If not then please point me in the right direction. My problem in short: I have problems using (pinning, mmu_update) physical pages from 0x900000 to 0xB1000 usualy. I''m writing my own little amd64 64bit toy kernel (based on Mini-OS as starting point) for xen and I run into problems with the way the start of day sets up the physical pages. My kernel

I re-wrote the compile script to build klibc (cleaning up how I do it, and how to find the source tarballs). It seems to be compiling fine. I tried several of the commands in usr/utils/static and most one. However, the sleep command fails in a strange way (EINVAL on execve): ================================================================ faraday/phil /home/phil/klibc-project-0 581> strace

Hi Rusty, I had a look over your 011-paravirt-head.S.patch. I'm struggling to come up with a list of any benefits over having separate entrypoints for each hypervisor. Multiple entry pros: * allows maximum startup flexibility for any given hypervisor * for Xen at least, it's pretty simple * the "what hypervisor am I under" question is answered trivially cons:

xc_dom_alloc_page deals with virtual address not physical address. When an ELF is loaded, virtual address and physical address may be different.

[ REPOST: Apologies to anyone who has seen this before. It didn't make it onto any of the lists it should have. -J ] Hi Andrew, This series of patches lays the basic ground work for the paravirtualized kernel patches coming later on. I think this lot is ready for the rough-and-tumble world of the -mm tree. For the most part, these patches do nothing or very little. The patches should
