[Spice-devel] C version of find_msb()

[Bryan Stillwell]

Recently I tried building the Ubuntu SPICE packages on powerpc and found
that the spicec package fails on some x86 assembly code in
common/gl_utils.h.  This motivated me to create an optimized C version
of the find_msb() function, which I've attached.

This patch allows people to build the spice-client on any 32bit/64bit
architecture, but it doesn't solve the endianess problems in the SPICE
protocol itself.  Has anyone looked into the network byte-ordering
issues?

I can see thin-clients based on ARM processors being pretty popular in
future.  In fact, I bet someone could build one today for under $200
with a plugcomputer and a displaylink usb video card:

Guruplug ($99)

HP USB Graphics Adapter NL571AT ($59)

I haven't tried this combination, but I see xorg packages for the
displaylink card in Ubuntu, however, they don't seem to be built for ARM
yet:

Thanks,
