I suggest you fix ether82598: it is OK to call qlock() and qunlock()

it's to allow the use during reset of a given driver's

of them, with and without the qlock.

in an interrupt function), as it previously was.

then you can get rid of the old definitions in /*/include/u.h
and declare a flag day. having both seems wrong to me.
you might as well just do a local hack for the go stuff at that
point.
the hard part is convincing

It is not a minute, one-off change.
I stand corrected.
I don't know how to fix it to
.../src/cmd/8a/asm.c, around line #900:

sh = newElfShdr(elfstr[ElfStrEmpty]);
My guess is that this needs to be followed by an instruction to write
out the header, which in fact does not take place.

The new build incantation is:
cd $GOROOT/src/pkg
make clean
mkdir -p $GROOT/bin/plan9
GOOS=plan9 GOBIN=$GOROOT/bin/plan9 make -k install
I won't try this until the mmap problem you refer to is resolved, so a
question is in order: are the plan 9 tools essential to the operation
of 8l with
The following executables are installed into $GOROOT/bin as Plan 9
a.out binaries when you run make -k install inside src/pkg:
cgo, ebnflint, gofix, gofmt, gotest, gotype, govet, goyacc, hgpatch.
They should be directed somewhere else by setting GOBIN, there is no
need to include them in your
the way to do this is
cd /sys/src; objtype=arm mk mk clean
Just getting to play with this... had to do some copying of some of
the files first among other setbacks... ok, plain mk asks what to make,
and so I tried 'mk all' which is saying 5c does not exist, but
that's one of the
I have tweaked the Plan 9 native ar.h to allow for manual adjustment
around the different needs of Go and native Plan 9 toolchains, so now:
#ifndef SARNAME
#define SARNAME 16
#endif
SARNAME can be predefined to the 64 that Go prefers. Unfortunately,
it's a short term
PS: I still can't link an executable with the version of 8l from the
Go toolchain that I built under Plan 9, but I'm hoping to get there
soon.
It's of some consolation to me that I see exactly the same results
under Ubuntu, so that particular problem isn't in the 8l executable
created for Plan
