* minios: Fix blkfront driver when sector_size != 512Keir Fraser2009-05-261-4/+4
| | | | | | | | The first and last sector as well as the sector number of the request is expressed in 512 bytes units, independently from the real sector size. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
* minios: Implement some extra lib functions for ocaml xenstored stubdomKeir Fraser2009-05-192-0/+38
| | | | | | | We could stub them out as unsupported, but we may as well implement them as they are very simple. Signed-off-by: Alex Zeffertt <alex.zeffertt@eu.citrix.com>
* minios: Define extra stub functions to allow build of ocaml xenstored stubdomKeir Fraser2009-05-191-1/+58
| | | | | | | These are referenced by the libs that ocamlopt links xenstored to, but ought not actually get called. Signed-off-by: Alex Zeffertt <alex.zeffertt@eu.citrix.com>
* stubdom: drop lwip supportKeir Fraser2009-04-233-11/+18
| | | | | | | | | | | | | | | | | | | | Network support is still provided the same way: using the tap interface, created in qemu using netfront. The lwip stack is still available to avoid additional compilation issues. However the stubdom is not going to have its own vif anymore, this means that the only vnc server supported is the one in dom0. You can still enable the vnc server in a stubdom at compile time, if you want so. Probably the most important change caused by this patch to xen users is that you don't have to specify two vif in the stubdom config file anymore, but just one: -vif = [ '', 'ip=10.0.1.1,mac=aa:00:00:12:23:34'] +vif = ['ip=10.0.1.1,mac=aa:00:00:12:23:34'] Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
* stubdoms: generate stubdom config fileKeir Fraser2009-04-231-4/+0
| | | | | | | | | | | | | | | | | | This patch removes the need for a second configuration file for stubdoms: it is going to be automatically generated by the script stubdom-dm using command line options and xenstore to find any needed information. The configuration script will be placed under /etc/xen/stubdoms and automatically removed when the domain is destroyed. The only change needed in xend is not to write on xenstore sdl, opengl and serial command line options for qemu, because stubdoms do not support them. It is safe to remove those two options from xenstore because qemu does not use xenstore to read commans line options. Finally this patch fixes blkfront disconnections from backends and display and xauthority variables for pv guests. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
* minios: fix a memory corruption in blkfrontKeir Fraser2009-04-141-5/+7
| | | | | | | | | The corruption happens every time we pass a sector aligned buffer (instead of a page aligned buffer) to blkfront_aio. To trigger the COW we have to write at least a byte to each page of the buffer, but we must be careful not to overwrite useful content.

* minios: allow to allocate machine contiguous pagesKeir Fraser2009-03-134-0/+152
| | | | | | | | This is a port of XenLinux xen_alloc_contig_memory() to mini-os. A sufficiently privileged mini-os guest can exchange a small number of its pages with machine contiguous pages. Signed-off-by: Rolf Neugebauer <rolf.neugebauer@netronome.com>
* minios: Fix 18874 memory clippingKeir Fraser2009-03-091-5/+8

* | [IA64] Remove the useless big endian stuff.dietmar.hahn@fujitsu-siemens.com2008-11-1815-410/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes all the useless big endian stuff from the mini-os. Before there was an effort to support big endian for PV-guest. But the big endian support was never gotten into the common parts of the mini-os so it makes no sense to have this only in the ia64 specific sources. And as there is no open source big endian os and porting our BS2000 os to ia64 was stopped, nobody wants that stuff in the common minos. So this looks ugly then and remove the big endian stuff.

* minios: do not expose #define current to applicationsKeir Fraser2008-10-273-6/+10
| | | | | | | | | | | | | | | | | Currently the minios headers do this: #define current get_current() Obviously when porting general code to this environment, this can cause problems ! The attached patch arranges for this only to be done if #define __MINIOS__ is declared, which is set up by the makefile in extras/mini-os. Suppressing the namespace pollution is necessary to get recent upstream qemu's to compile, since they (quite properly) use `current' as an ordinary identifier.
