installing on thinkpad x201i

[Johan Danielsson <joda%netbsd.org@localhost>]

Hello,

I've been trying to install NetBSD/amd64 on a Thinkpad X201i (Core
i3). I would say I've come to a point where it's usable.

At first, kernels would crash pretty much immediately. This was true
for both 5.0.x, and current, both i386 and amd64. After some poking
around I figured out that the problem was that iomem extent storage
was too small. This BIOS seem to announce 33 (IIRC) memory segments,
and there is only room for 16 in iomem_ex_storage. With this number
bumped to 40, it made it all the way to single users mode, with most
hardware detected.

Is there a reason (other than historical) for this low number (16), or
can this be increased with out problem (other than the loss of a few
bytes)? Can I commit this change, or should this be solved in some
different way altogether?

 static int ioport_malloc_safe;

Second, the i82577 PHY lacks a proper driver. I don't know if any of
the present intel phy drivers (iophy, igphy, ikphy, have I missed
any?) are close enough, but they don't match as is.

To get ukphy to work, I had to remove the PHY reset; all registers
read as zero after reset. I suppose this PHY needs some special voodoo
after reset.

The "final" big issue is X. Our aging X source doesn't know about the
fancy Intel GMA HD graphics. The VESA driver works, but it just a bit
too slow for comfort. Is anyone actively working on fixing this?
Moving to modern versions seem to be quite a lot of work involving
lots of TLA:s (GEM, KMS and whatnot). Personally I would be ok with
something that's a bit faster than VESA (like moving windows
effortlessly).

Other than this, WLAN (Intel 6200) seems to work (except for 11n), BT
and memory card reader attaches, but I haven't used them, neither have
I tried audio, suspend, or any other features.
