Hello
I was having some trouble on an old ThinkPad x201i with intel
integrated graphics. So was thinking of trying something as an effort
to fix it.
Not so accustomed in building kernel from source, let alone debugging
it.
I wonder if I'm doing anything wrong or is there any solution to this.
Please help.
Tried this on NetBSD 10.0 x86_64:
# ftp https://cdn.NetBSD.org/pub/NetBSD/NetBSD-$(uname
-r)/source/sets/syssrc.tgz
# tar zxvf syssrc.tgz -C /
# cd /usr/src/sys/arch/$(uname -m)/conf/
# cp GENERIC MYKERNEL
Uncommented and changed the ident line and uncommented the
"i915drm* at drm?" line on MYKERNEL.
Then:
# config MYKERNEL
# cd ../compile/MYKERNEL
# make depend
# make
make ends with (output attached):
# link MYKERNEL/netbsd
ld -Map netbsd.map --cref -T netbsd.ldscript -Ttext 0xffffffff80200000
-e start -z max-page-size=0x200000 -X -o netbsd
