[Xen-devel] Status of my recent PCI pass-through changes
Hi, As of changeset "passthrough: Update acpi_php_readb()''s comment" [ 182efd7df38a23e14294811db56fc45d8654713e ] of the staging tree of qemu-xen-unstable, all of the patches relating to recent changes to PCI pass-through that I have been involved in appear to have been merged. The following changes seem to be out-standing for xen-unstable as of change-set "x86 acpi: Delete unnecessary and broken RSDP-scanning code" [ 19433:d5ddc782bc49 ] . Please consider including them in 3.4. * "[patch] xend: Supply pass-through vslot to qemu-dm" http://lists.xensource.com/archives/html/xen-devel/2009-03/msg01630.html * "[patch] xend: Allow user to specify vslots 0 - 1f for static pass-through" http://lists.xensource.com/archives/html/xen-devel/2009-03/msg01678.html * "[patch v2] hmvloader: Reserve ioport ranges for expanded PHP" http://lists.xensource.com/archives/html/xen-devel/2009-03/msg01939.html * "[patch] hvmloader: Use If and Else instead of Switch" http://lists.xensource.com/archives/html/xen-devel/2009-03/msg01940.html For reference, these patches relate to the following changes: * Allow any unused PCI slot to be used for PCI pass-through, including hot-plug. Previously only slots 6 & 7 could be used, limiting users to two pass-through devices per domU. The new limit is around 28, as there are 32 possible slots on a PCI bus, and at least 4 are used by a domU at boot-time. Fewer devices will be available for pass-through if extra ioemu devices are attached to the domU. * Allow the user to specify slot used for pass-through of devices attached to domU at boot time. This mirrors the ability to select the slot when a device is hot-plugged. Thanks to everyone who has helped with reviewing and merging so far. -- Simon Horman VA Linux Systems Japan K.K., Sydney, Australia Satellite Office H: www.vergenet.net/~horms/ W: www.valinux.co.jp/en _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
