Re: pm2fb driver

Dear Michael-san.

Hello.

I carry out a test according to your instructions.

====================
NetBSD/alpha

I agree with you.
It may seem strange, nevertheless it is a fact.

====================

It is quite impossible.

XFree86 is the default for NetBSD/alpha.(Support ancient chip)

See:
http://nxr.netbsd.org/xref/src/share/mk/bsd.own.mk#1019

and

Xorg is broken on NetBSD/alpha.
I think that X cannot map /dev/mem.

See:
http://mail-index.netbsd.org/port-alpha/2014/09/27/msg000710.html
http://mail-index.netbsd.org/port-alpha/2012/06/16/msg000545.html
http://mail-index.netbsd.org/port-alpha/2011/04/17/msg000443.html

I tried to fix this problem, but I was give up.
I and tsutsui-san was fixed bus_space_mmap's problem instead of it.

See:
http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=48431

Therefore, I use only wsfb-driver.
====================

I think that all problem are solved!

Please modify /sys/arch/alpha/conf/GENERIC!

I am very happy that I was able to work with you.
