[Qemu-devel] [PATCH v2] target-i386: move generic memory hotplug methods to DSDTs

[Qemu-devel] [PATCH v2] target-i386: move generic memory hotplug methods to DSDTs

[Paolo Bonzini]

This makes it simpler to keep the SSDT byte-for-byte identical for a
given machine type, which is a goal we want to have for 2.2 and newer
types.

Moving static code to DSDT is resonable, hence

Reviewed-by: Igor Mammedov <imammedo@redhat.com>

tested with xp3/ws2003 wich were happy with this patch.

---
however I'm not sure that SSDT byte-for-byte compatible will make
things better.
Since SSDT includes snippets of AML compiled by IASL, hex-templates
could be different depending on IASL version. Ultimately
that would make us to keep versioned by machine type binary templates
so that we could guaranty byte-to-byte identity.

Perhaps we should reconsider and think one more time about
http://lists.gnu.org/archive/html/qemu-stable/2014-07/msg00205.html

which solves migration size issue and doesn't tie us to maintanance
nightmare with versioned tables. I'd preffer to keep tables
un-versioned as long as possible.

Re: [Qemu-devel] [PATCH v2] target-i386: move generic memory hotplug methods to DSDTs

SSDT is simple enough that there shouldn't be differences.  If this were
a problem, we could unconditionally use .hex.generated files or move the
generation entirely to C, similar to what we do for bridges and what
SeaBIOS used to do.
